Patent GB-127012-A (GB)
Title: Improvements in or relating to Electrical Driving Gear, particularly for Motor Cars.
Inventor: CROCHAT HENRY
IPC: H02P9/00
Filed: 1917-02-21
Abstract: 127,012. Grochat, H. Dec. 15, 1916, [Convention date]. Systems for continuout - current motors only.-In electric-vehicle driving arrangements of the kind described in Specification 102,864, particularly for vehicles having endless tracks which are steered by driving the tracks at different speeds, and in which series motors having their armatures in parallel drive independent shafts, the fields of each of t'he motors are divided into two parts a<1>, a<2>, b<1>, b<2>, the parts a<1> b<1> being arranged in series, and the parts a<2>, b<2> in parallel. Steering is effected as follows. The part field a<2> or b<2> of the motor, which is to run faster, may be adjusted by a variable resistance. Resistance may be inserted in the circuit of the armature on the shaft, which is to rotate slower, or the circuit may be opened; or this armature may be short-circuited either alone through an adjustable resistance, or with its part-field a<2> or b<2>. Braking of the vehicle is effected by running the two motors as generators to supply the dynamo c, which will then act as a motor working the attached explosion engine as an air-compressor, the armature circuits being connected by a balance wire. Regulation of the braking is effected by a variable shunt resistance to the dynamo field c<1>, by acting on the admission valves of, or by varying the timing of the ignition of, the engine. The above-described alterations in the circuit arrangements for steering may be effected by switches closed or opened by cams mounted cn a single shaft.

Patent GB-1370417-A (GB)
Title: Fluidic circuit devices
IPC: F15C3/04
Filed: 1973-01-18
Abstract: 1370417 Valves BEKAERT SA NV 18 Jan 1973 2641/73 Heading F2V [Also in Division G4] A fluidic OR gate has a flexible valve member extending across all the inlet ports. Fluid appearing at any input port displaces the member away from that port, sealing any unpressurized ports while allowing fluid to pass from the pressurized port or ports to an outlet chamber. The mechanical characteristics of the member are such that, in the absence of inlets, pressure in the outlet chamber cannot cause the member to seal all of the inlets, and consequently the pressure is relieved via one of the inlets. In one embodiment the valve member is a ring 21, Figs. 1 and 4, surrounding a cylindrical part 1 having inlet ports 10-12. The outlet chamber is annular, being defined by ring 21 and annular wall 22. Part 1 and wall 22 are sandwiched between flat plates, the height of ring 21 being slightly less than the distance between the plates. Fluid issuing from any one or more of the inlets, e.g. inlet 11 as in Fig. 4, displaces ring 21 so that it seals the remaining ports against ingress of fluid from the outlet chamber. Fluid from the pressurized ports flows between the end faces of the ring and the plates, passing to outlet port (24), Fig. 3 (not shown), via the annular chamber. When no inlet is pressurized reverse flow can occur since the ring can not seal all the inlet ports, so relieving pressure in the outlet chamber. In a second embodiment, Fig. 6b, the inlet ports A-D are disposed in a line, with valve member 37 extending across them. Fluid passing over member 37 enters chamber 31 and exits at outlet 32. In another embodiment, Figs. 7a, 7b (not shown), the wall having the inlet ports is curved.

Title: Improvements in or relating to the treatment of material to render it gas tight
IPC: D06M15/05
Filed: 1928-01-30
Abstract: 284,584. B. G. Textilwerk Ges., and Strobl, H. Jan. 29, 1927, [Convention date]. Proofing against air and gases; waterproofing; proofing compositions: single coatings; multiple superposed coatings.-Gastight fabric for use in balloons &c. is made by applying a mixture of viscose, a substance such as gelatine, and a hygroscopic softening agent such as glycerine, to the fabric. Preferably a number of coatings are applied, the individual coatings containing varying percentages of viscose. The first coating preferably contains a higher proportion of gelatine, the intermediate coatings higher proportions of viscose, while the outer coatings contain less viscose. The fabric may be waterproofed before treatment, and several layers of fabric previously waterproofed may be united by a layer containing viscose. Creosote may be added to the gelatine as a preservative, and a substance such as formaldehyde may be added to render the gelatine water resistant. The viscose may be rendered neutral by adding acids to the composition before or after application to the fabric. A protective coating of oil, varnish, &c., or aluminium powder may be applied to the material.
Patent GB-608643-A (GB)
Title: Food dispensing apparatus
IPC: F25D25/00
Filed: 1946-01-30
Abstract: 608,643. Food-dispensing apparatus. CEASE, W. W. Jan. 30, 1946, No. 2947. Convention date, Sept. 17, 1945. [Classes 27 and 116] A food-dispensing apparatus, which may be coin-controlled, comprises a container 10, Fig. 2, channel members 26 for supporting plates 18, means for moving the plates, in a row, successively through an opening 67, and means for raising the vertically adjacent row of plates to the level of the opening 67, when all the plates in the row at the opening have been dispensed. Alternatively the plate may move downwardly to a lower dispensing opening. The container may be either heated or cooled; and the correct humidity is maintained therein by water in a pan 35. Circular or rectangular plates are loaded into the container through a door 29. To dispense the plates through the opening 67-normally closed by a spring-flap 68-a rod 46 is moved outwardly which movement causes spring-urged fingers 52, 53, Fig. 3, engaged behind the plates, to move them outwardly. The fingers are fixed to a panel 40 mounted on rods 43, 44 by guide blocks 41, 42. At the end of a dispensing operation the panel 40 is automatically returned by a counterweight. Springs are provided at the ends of the rods 43, 44 to cushion the impact of the blocks, on their return. To prevent the return of the rod 46, until all the plates in a row have been dispensed, a spring- urged pawl 71 co-operates with a rack 70 on the panel 40. The rack is of such a length that the pawl is freed, when the rod 46 and the panel 40 have been moved to the end of their stroke. The means for automatically raising the next row of plates when a row has been completely dispensed comprises a longitudinal rail 75, pivotally mounted at 77, which is kept in a raised position by any plate in the row being dspensed. When all the plates in the row have been dispensed the rail drops, causing a push rod 80 to move down and move an arm 105, Fig. 8, to the right. This movement withdraws a clutch pin 98 allowing a pawl 95 mounted on a disc 94 to engage a driven ratchet wheel 89. The disc 94 and wheel 89 then rotate together. Rotation of the disc, rotates a shaft 90 causing oscillation of a link 112, Fig. 3, which oscillation causes a pawl 117 to move a ratchet wheel 118. One rotation of the shaft 90 corresponds to a quarter of a revolution of the wheel 118. Return movement of the wheel 118 is prevented by pawl 119. The quarter of a revolution of the wheel 118 causes, through suitable chains and sprockets, an upward movement of the plates corresponding to the distance between adjacent rows. The plates on the raised row lift the rail 75 causing disengagement of the disc 94 and wheel 89. If a row does not contain any plates, the disc and wheel will remain in engagement, causing a further upward movement.
