Title: Improvements in or relating to pressure medium brakes and steering devices for aircraft
IPC: B64C25/48
Filed: 1930-07-15
Abstract: 346,630. Aircraft wheel braking systems. KNORR-BREMSE AKT.-GES., 9, Neue Bahnhofstrasse, Lichtenberg, and KOLLINEK, K., 16A, Hentigstrasse, Karlshorst, both in Berlin. July 15, 1930, No. 21435. [Class 4.] A fluid pressure wheel brake and steering device for aircraft operated by a differential gear, has a member controlled by the gear adapted to place the pipes leading from the brake valves to the respective brake cylinders in communication with each other through branch pipes for uniform brake application and to interrupt such communication when the brake valves are operated differentially for steering the aircraft. Two brake valves a are operated equally or differentially by a differential gear e, g, h and levers l, k so as to admit pressure fluid to pipes b leading to the brake cylinders. The lower ends of the levers l have toothed sectors m gearing with sectors n on the spindles of rotary valves p bearing on opposite sides of a partition t in a housing v pivoted in the side walls w of the gear. The housing v is geared to the housing f of the differential gear by teeth t<1> so that when both valves a are operated equally the valves p and partition r are rotated by equal amounts and passages s, s<1> remain in alignment so as to keep branch pipes u from the pipes b in communication with one another to equalize the braking pressure. Differential operation of the valves a results in opposite rotations of the valves p and communication through the passages s, s<1> is interrupted. Flexible sections x connect the pipes u to the housing v.

Abstract: 576,733. Cooling liquids. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Dec. 23, 1943, Nos. 21514 and 21515. Convention dates, Dec. 31, 1942 and June 1, 1943. [Class 29] [Also in Groups VI and XVIII] A self-contained apparatus for cooling, carbonating, syruping and dispensing beverages comprises concentric cooling and carbonating chambers with a refrigerant expansion chamber between them, the liquid to be treated being arranged to flow in both chambers over extended cooling surfaces which are in thermal contact with the refrigerant chamber. As shown, a heat-insulated tank 11 encloses concentric tanks 12, 13. The tank 11 is fitted with baffles 34 provided with staggered holes 33 and secured to the tank 12, and is divided by suitable partitions into a water reservoir 21 and three syrup reservoirs 23, 24. The tank 13 is provided with dished, perforated baffles 65 and encloses a carbon dioxide supply pipe 14 and a water supply pipe 15 which opens above a spreader 16. The tanks are enclosed in an outer casing 10 which houses also a carbon dioxide cylinder 71 and a refrigerating machine indicated at 59. The latter circulates refrigerant through the space 20 between the tanks 12, 13. Water is supplied to the reservoir 21 by a pump 32a controlled automatically to maintain a pressure in the reservoir 21 greater than that in the carbonating tank 13. The water is cooled by passage over the baffles 34 and passes to the top of the tank 13 by pipes 35, 15 under control of a float valve 36. Here it meets carbon dioxide supplied by pipes 70, 14 and is further cooled by passage over the baffles 65. The cooled carbonated water collects in the lower end of the tank 13 and is forced by the gas pressure in the tank through a pipe 40 with manual valve 42 to the dispensing nozzle 41. The syrup tanks are under pressure from the cylinder 71 through pipes 74, and communicate with the nozzle 41 by pipes 47, 51, 53 and valves 48, 52, 64. The valves and the nozzle 41 are carried in a heavy metal body 55 connected to the tanks 12 so that it is cooled by the refrigerant in the space 20. A vessel 81 to receive the beverage is supported on a shelf 80 with a drain pipe 82.

IPC: F16P3/04
Filed: 1920-07-19
Abstract: 170,638. Day, E. July 19, 1920. Guards, controlling .-A guard f, for stamping- presses &c., which may also act as a work-stripper for the top tool, is carried by a lever e linked to a slide d, and falls by its unaided weight into the protective position when so permitted by the raising of a blocking- lever c out of the path of the slide d. When a treadlerod a, in its first movement, has lifted the lever c far enough to allow full descent of the guard f, a pin a<1> on the rod a reaches the end of a slot in a lever b, on which the lever c is pivoted. The lever b is connected by linkage i to the starting-clutch, and also to a slide h, engaging by inclined surfaces h', g<1> a bolt g, which can move to release the starting-gear only when aligned with a notch d<1> in the slide d, that is, when the complete descent of the guard is unobstructed. The guard is locked by the bolt g, and is raised, when released, by the superior weight of the treadle &c., the bolt g being withdrawn by a spring or other automatic means. As the guard is not positively moved downwards, the operator's fingers are not liable to injury thereby.

Title: Improvements relating to electromagnetically operated brakes for motor road and other vehicles
IPC: B60T13/74
Filed: 1930-07-17
Abstract: 359,033. Electromagnetic brakes; hand or foot actuation. LUVAX, Ltd. and PITT, H. W., Larden Road, Acton, London. July 17, 1930, No. 21643. [Class 103 (i).] Upon failure of the current in an electromagnetically operated brake, the operating lever is coupled to an alternative brake such as a mechanically operated brake. As shown in Fig. 1, the pedal a which actuates the controller b of an electromagnetically operated brake has connected to it a slotted link in which is disposed a pin g on the lever d of a mechanically operated brake. The link c carries a pawl f which engages the pin g so that the pedal operates the lever d if a magnet h in the electric brake circuit is not energized when the pedal is moved. In another construction, the pedal a carries the pin g and the slotted part is carried by a lever which is co-axial with the pedal. Fig. 3 shows a further form in which the pedal a freely mounted on the shaft j of the mechanical brake, has projections k between which are projections m on a collar secured to the shaft. A pawl f on the pedal fills the gap between the projections m, k if the magnet h is de-energized and so couples the pedal to the shaft. The mechanical operating mechanism may actuate the same brake shoes as the electric control or it may actuate other shoes acting on the same or different brake drums.
