Title: A fluid control gate valve
IPC: F16K3/36
Filed: 1957-07-22
Abstract: 861,969. Valves. BUTLER, G. A. July 22, 1957 [Nov. 23, 1956], No. 23180/57. Class 135. The valve 10, Fig. 1, has aligned and opposed bores 11, 12 that open into a chamber 13 in which latter are disposed two identical annular valve-seats 21, 22 each having a neck 24 that is located in an enlargement of the associated bore 11 or 12. A pair of gate valve closures 28, 29 positioned between the seats is connected to a nut 31 movable axially by a threaded shaft 32 that passes through the bonnet 19 and is fixed to a hand wheel 33 ; the closures have openings 35 therethrough which when aligned with the bores 11, 12 form the fluid passage through the valve. Each seat extends upwardly to provide valveguiding surfaces 40 and reservoirs 42 for sealing materiel, which reservoirs are connected to grooves 46 and 49 via passages 44, 45, 50 and 48 ; the passages 50 are disposed in the valve closure. Each seat projects laterally beyond the closures, the projections being vertically grooved to house the ends of curved wedges 55, each of which resiliently urges the two seats apart as well as acting as closure guides. Since there is a considerable clearance between the seat necks and the co-operating bore enlargements a packing ring 60 is provided on the inner side of each groove 49 to prevent fluid in chamber 13 entering therein. If, when the valve is closed, one closure is forced by pressure differential away from its seat then no sealant flows from the associated reservoir since the latter is directly open at the top, and indirectly at the bottom through groove 46, with the pressure fluid that has leaked into chamber 13 ; however, the other reservoir is under pressure at the top only so that sealing material flows therefrom to the grooves of the other closure.

Filed: 1929-07-29
Abstract: 331,716. Walt, J. van der, and Du Plessis, H. P. July 29, 1929. Animal traps. - A trap has a passage having entrance 2, 3, Fig. 2, at its ends, and vertical spindles 7, 8 arranged at one side of the passage; said spindles carry horizontal parallel rods 9, 10 and are adapted to be rotated, in opposite directions by means of either a spring 23 or a weight 78 through the agency of bevel pinions 13, 14, 18, 19 and gearing 21, 22. The animal entering at 2 or 3 and encountering either of the barriers 40, 41 jumps over it and alights on a plate 32, thus releasing the catch 33 and causing the rotation of the spindles 7. 8 and the rods 9, 10. The animal is thus driven, into the compartment 42, and steps on and depresses the plate 47, thus opening the swing self-closing door 49. The door 59 is operated in similar fashion by the animal, which thus enters a detachable cage fastened in position by means 65. Pointed wires 38, 39 prevent withdrawal from the passage, and a bait receptacle 73 is provided.

Filed: 1975-05-30
Abstract: 1495435 Pulse width modulated amplifiers; sawtooth generators SONY CORP 30 May 1975 [6 June 1974] 23667/75 Heading H3T In an amplifier, the input signal at 1, Fig. 2 is pulse width modulated on to a carrier signal at 4 and phase split at 4 to provide antiphase signals which are demodulated by low pass filters and used to drive a load in push-pull. The amplitudes of the antiphase signals are balanced by a differential amplifier feeding back to the input amplifier 1. The modulator, comprises a sawtooth generator 16, 17, Fig. 3, whose output is compared with the input signal in a differential amplifier 25a, 25b to produce pulses at the output 29 which are width modulated in dependence upon the amplitude of the input signal. The sawtooth waveform is produced by applying a square wave from oscillator 3 to set a flip-flop 10. The resulting high output from Q turns on transistor 14 to discharge capacitor 21 and reset the flip-flop. Capacitor 21 is then charged by a constant current source 19, 20, 21 until discharged in response to the next pulse from oscillator 3.

Title: Process for drying and/or calcining powdered, granular or similar materials
IPC: B01J6/00
Filed: 1956-08-02
Abstract: The rotary drum drier shown, which comprises pre-mixing, calcining and finishing zones A, B, C respectively, is heated by steam pipes 2 and may be fitted with paddles throughout the whole or part of its length.  Moist sodium bicarbonate is fed to the drum 1 at 6 and partly finished material is extracted at the entry 9 of the zone C and passed, by means of a recycling conveyer 4, comprising a tube fitted with an internal screw 3, to an upstream point 5 thus ensuring that moist material is always fed on to partially dried material. The point 9 is so chosen that the partially dried material mixing <PICT:0799251/III/1> with the moist material is sufficiently dry to absorb the water in the bicarbonate and fix virtually all of it as a hydrate.  The steam and gases given off by the decomposition reaction are removed at 8 and the ratio of the quantity of recycled product to that of the sodium carbonate produced is between 1 and 3.  The conveyer 4, which is integral with the drum 1, may be replaced by a conveyer outside the drum the extraction of material therefrom being through holes in its wall.  The drum may be heated by an external solid, liquid or gas fuel heater the flue gas passes of which totally or partially envelop the drum, the heat transfer taking place through the drum wall.  Dense sodium carbonate may be made in the drum by the dehydration of moist sodium carbonate monohydrate.

Abstract: 795,725. Wrapping and unwrapping pipes. UNITED STATES RUBBER CO. Aug. 17, 1954 [Oct. 15, 1953], No. 23862/54. Class 99(2). A cloth strip for temporarily wrapping during curing a length of uncured rubber hose H, Fig. 1, on a mandrel is helically wound on to or off the hose H as pneumatically-operated gripping means 20, 48 together feed the hose from the left or right respectively through a rotating head 94 carrying strip feed and take-up spindles 101, Fig. 4, and 119 and a hose support 133<SP>1</SP>, Fig. 6. The hose feeds 20, 48 are driven through gearing from a main shaft 13 powered by an electric motor 103 via gears 104, 105, a variablespeed gear R, a pneumatically-actuated friction clutch 107 and gears 108, 109. The feed 20 comprises coacting rollers on toothed quadrants which are operable by a rack 38 under the control of a pneumatic cylinder 37 to bring the rollers to bear on the hose from opposite sides. The feed 48 comprises co-acting caterpillar tracks having central V-grooves locating on the hose from above and below, the tracks being movable towards and away from each other by mounting each complete track assembly slidably on two shafts 68 and interconnecting them by racks 74, 75 meshing a pinion 78, the assemblies being slid by a pneumatic cylinder 81 whose piston 80 is fast with one assembly. The input shaft 100 of the gear R passes therethrough to carry a gear 99 meshing via an idler 97 a gear 96 fast with the rotating head 94 to drive it and fast with a gear 131 meshing a gear 132 driving, via a friction slip clutch 130, a shaft 128 having a gear 127 meshing one set of teeth 124 of a member mounted on rollers 125 on the head 94 and whose other set of teeth 123 mesh a gear 122 on the strip take-up spindle 119, the gearing ratios being such that the clutch 130 is always overdriven and the spindle 119 therefore always maintains tension in the strip as it takes it up from the hose on unwrapping. To ensure that the strip forms a cylindrical package on the spindle 119, it passes thereto in a path over a projecting leg 133 of the channel-shaped hose support 133<SP>1</SP> and over pins 134, 135, 136 on the head 94. During wrapping, this path is used in the reverse direction in conjunction with the strip feed spindle 101 which is freely revoluble on the head 94 but retarded by a brake 102 to maintain strip tension. At the beginning and end of wrapping, spiral finishing turns may be put on by operation with the clutch 107 disengaged.
