Dear friends, In the posting serial numbers were not in order. One spelling mistake dog's front legs (instead of friend legs) by space check. I request members to read the corrected one pasted below:-Gopala krishnan GATE(PURAVATHIL)
Dear friends, I am attracted to a recent SURF POWDER advertisement.The small dog went out of the home, but entrance gate was locked. The dog triesto enter making a pit below the nearby vertical grill and a small boy helps tomake an oval shape removing the soil. His dress becomes dirty while making thepit, dog enters through the oval hole inside home. No worry, surf would remove in single wash the dirtfrom soil in the cloths . The small dog uses its brain and tries to enter bymaking a pit below the grill. The onlytool it has are its front legs. During earlier days on the outer compound wall there mightbe a rest room and shelterin the entrance(Patippura). Recent homes are also built withPatippura in Kerala, going back to the old style of construction with newmaterials. All wooden works of yesteryears are done in concrete, giving finishand appearance of wood. This posting is about different types of gates nowcommonly available and some others earlier used. Some information are compiledfrom Wikipedia. Sincerely, Gopala Krishnan. 5-6-2021 1 Grill Collapsiblegate All banking institutions are now providedwith collapsible gate in the entrance and kept opened to such an extent onlyone can enter at a time. If people are bulky, they have to turn and enter. 2 Rotating gate Many banks have a rotating gate next to collapsiblegate. This rotating gate ensure only one can enter or go out at a time. Earlier days many homes had such rotating gate whichwould be pushed and people of the home used to enter. This also was locked inthe night. Large animals cannot push andenter through the gate. But dogs, cats etc. can enter. 3. Small gateand large gate Buildings constructed about 15 years back gaveprovision to two gates. One small entrance for people and big entrance forvehicles to portico. These gates opened either forward or back ward. Callingbell provision is given in the fixing wall. Gates erected nowadays are allgrill works. If covering is required it is done over grill work with steel/ironplates and fitted on frame work. 4 sliding gate. Where space to open backward was a criteria, and movingside way was more flexible, gate was provided as sliding to sides. Both largeand small gated can be provided in the manner. Compound walls should be built first in the south-westdirection. Avoid placing a gate in the south side or extreme corners. Use soft colours for the front gatesuch as white, silver or wood colours 5 Some gateinformation Which gate isbetter iron or steel? If strength is a big requirement for your gate thensteel will probably be the better suited material for you. Stronger than iron,steel is highly dependent on the skill of the welder / metal fabricator youchoose. What is an entrancegate? An entrance gate is a fence that provides a practical,safe, and secure entryway. An entrance gate is sometimes called an entry gateand is often used for searches at concerts, festivals, and (sports) events. Which directionshould a gate open? A gate should always swing inward toward privatespace, not outward toward public space. The hinges can be placed on either sideof a single gate. 6. Jail gate Jail gate is a big gate strong and has a small openingdoor permitting prisoners to go out after punishment period is over. It is aguarded gate and kept locked always. Only for permitting prisoners to go out,the gate is used. 7 Both way gate In the entrance of flats, big institutions gates areprovided separately for entranceand exit. Normallyentrance gate check all particulars before getting in the institutions. Some gate information compiled from Wikipediaare given below. Some of these are used in different names by us. 8 Front gateand back gate Some railway stations can be entered through front andback gates. Though the word gate is used, actually it is an entrance.Bangalore, Tambaram, Trivandrum etc. stations have front and back gates 9 Baby gate A baby gate or child safety gate is a protectivebarrier designed to prevent babies and toddlers from accessing areas of a homewhere they might be unsafe, such as stairways and kitchens and outside. Babygates are typically constructed of metal, plastic and/or wood, and can beexpanded to fit in a range of doorway widths. They may be designed for useindoors or out, and may be either hardware or pressure-mounted. Pressure-mounted gates are typically held in place byfriction with the walls on either side, while hardware-mounted gates arescrewed into the wall studs and swing fully open like a door. There arehardware-mounted gates that can be customized to fit wide and irregularlyshaped openings, as well as mesh retractable gates that roll out of the way. Baby gates are also frequently used to contain smallpets, especially ones that are not housebroken. A pet gate may not meet thevoluntary standard for baby gates. Baby gates are typically removed once a child iscapable of opening or climbing over the gate. Most of us haveprovided a small wooden gate fitted to one side and hinged other side in themain door when our children were 2-3 years. Sometimes it would be two or three removable battensacross door frame as baby gate. 10 Defensive wall A defensive wall is a fortification usually used toprotect a city, town or other settlement from potential aggressors. The wallscan range from simple palisades or earthworks to extensive militaryfortifications with towers, bastions and gates for access to the city. From ancient tomodern times, they were used to enclose settlements. Generally, these arereferred to as city walls or town walls, although there were also walls, suchas the Great Wall of China, Walls of Benin, Hadrian's Wall, Anastasia Wall, andthe Atlantic Wall, which extended far beyond the borders of a city and wereused to enclose regions or mark territorial boundaries. In mountainous terrain,defensive walls such as letzis were used in combination with castles to sealvalleys from potential attack. Beyond their defensive utility, many walls alsohad important symbolic functions – representing the status and independence ofthe communities they embraced. Existing ancient walls are almost always masonrystructures, although brick and timber-built variants are also known. Dependingon the topography of the area surrounding the city or the settlement the wallis intended to protect, elements of the terrain such as rivers or coastlinesmay be incorporated in order to make the wall more effective. Walls may only be crossed by entering the appropriatecity gate and are often supplemented with towers. The practice of buildingthese massive walls, though having its origins in prehistory, was refinedduring the rise of city-states, and energetic wall-building continued into themedieval period and beyond in certain parts of Europe. Simpler defensive walls of earth or stone, thrown uparound hillforts, ringworks, early castles and the like, tend to be referred toas ramparts or banks. My note- Pondicherystate has entrance arch- not a gate from all the sides 11 Hampshiregate, Hampshire gate, New Zealand gate or wire gate is atype of agricultural gate formed from a section of wire fence which can beremoved temporarily. This type of gate has many different local namesthroughout the world, sometimes hinting at its rough-and-ready nature and cheapconstruction. The term "Hampshire gate" is widely used in Britain(including Hampshire) – the names of other counties are occasionallysubstituted, or more often that of New Zealand. The common barbedwire version was originally used in the United States. This type of gate is used where access is only neededoccasionally, or when the cost of a conventional rigid gate cannot be justified.It does not require the heavy gateposts needed to support the weight of a rigidgate, it can be adapted to a variety of terrains, it is cheap and simple tomake, and if necessary it can easily be made much wider than a conventionalgate. A Hampshire gate occupies a gateway in a fence similarto that used for a conventional gate. However, instead of a rigid gate, a shortsection of loose wire fence fits into the gap – this may consist of wirenetting or barbed wire, and it usually matches the adjacent fence. One end of the wire is attached permanently to themain fence, and two or more short posts or battens keep it upright and flat –one of these is at the loose end. When the "gate" is closed, this end post fits into a loop ofwire at the base of the fixed fence, and the top is then pulled tight totension it. The top of the post may be held by another loop of wire,or additional tension may be provided by a length of chain looped around thepost and hooked onto a nail. Typical uses for a Hampshire gate include givingoccasional access between adjacent landowners, giving access to small woods forforestry operations, rotational grazing, or allowing unusually large traffic tobypass a normal route. In the AmericanWest, it is extremely common in rural areas, particularly on ranches, where itis the most frequently used type of gate used between pastures, and in fence linesseparating rangeland of different owners, or separating public and privateland. 12 Kissing gate A Kissing gateis a type of gate that allows people, but not livestock, to pass through. The normal construction is a half-round, rectangular,trapezoidal or V-shaped part-enclosure with the free end of a hinged gatetrapped between its arms. When the gate is touching an arm it must be pulled orpushed to pass through. The gate may need to be pushed to give access to thesmall enclosure, and when in the enclosure the person pulls the gate past thebulk of the enclosure to exit. Some examples have latches. Most are installedself-closing, to the side away from the pasture (livestock field), by hingegeometry, a spring or weight. The gate may bemade large enough to fit wheelchairs and the like. Alternatively, to allow pushchairs, wheelchairs,bicycles, and other things too large to pass through, a conventional gate witha less consistent swing-back or default animal-proof mechanism may be nearby,or an additional latch may allow it to open more fully. The name comesfrom the gate merely "kissing" (touching) the inside of theenclosure. It reliably forms a barrier rather than needing to be securely latched on each use. 13 lych gate A lych gate, is a gateway covered with a roof found atthe entrance to a traditional English or English-style churchyard. The nameresurrection gate is also used. SwedenMon (門, gate) is ageneric Japanese term for gate often used, either alone or as a suffix, in referring to themany gates used by Buddhist temples, Shinto shrines and traditional-stylebuildings and castles.

All the chip circuits would have thousands of logic circuits 19a what typesof gates are there? The basic logic gates are classified into seven types:AND gate, OR gate, XOR gate, NAND gate, NOR gate, XNOR gate, and NOT gate. The truth table is used to show the logic gatefunction. All the logic gates have two inputs except the NOT gate, which hasonly one input. -- You received this message because you are subscribed to the Google Groups "Thatha_Patty" group.
