Filed: 1937-08-30
Abstract: 501,533. Vehicle spring - suspensions. WEDELSTAEDT, W. VON. Aug. 30, 1937, No. 23738. Convention date, Aug. 29, 1936. [Class 108 (ii)] In a suspension for road vehicles in which the body is carried by means of levers pivoted to the axle or undercarriage the pivots on the axle &c. are displaceable in a transverse direction against the action of a spring to absorb the oscillations of the body and to enable it to cant on curves. The body A is carried by elbow levers g, h, and e,f having end rollers c, d and a, b respectively adapted to roll along the sides and bottom of the body in guides q, rand o, p as shown. The pivots k, i on the axle are arranged to be displaceable transversely in guides m, l against the action of a spring n. Shock absorbers t, s are also provided. When the body is unduly loaded the pivots k, i are forced to the other extreme ends of the guides m, l while the rollers c, a, are forced to the top ends of the guides q, o and the rollers d, b to the outer ends of the guides r, p. Fig. '3 shows the positions of the levers with their pivots and rollers when the car is traversing a curve.. Fig. 4 shows the positions when one wheel passes over an obstruction the pivot i at that end being forced to the outer side of the guide l and the rollers a, b tending, towards the positions shown.

Title: Data Processing System with Controls to Deal with Requests from Subsystem for Prohibited Operations
IPC: G06F13/26
Filed: 1967-05-23
Abstract: 1,164,000. Data processing. GENERAL ELECTRIC CO. 23 May, 1967 [25 May, 1966], No. 23874/67. Heading G4A. In a data processing system, an attempted prohibited action by one of a plurality of subsystems at the controller causes supply of a code to all the sub-systems and a pulse to the one sub-system. Memories have associated memory controllers which can receive commands from various subsystems, viz. processors and input/output controllers, on a priority basis. The command code from the selected sub-system to a given memory controller may be accompanied by a memory address and a data word. The command code is decoded in the memory controller and may cause one of the usual types of memory access or may load the data word into either an upper or a lower file protect register. In the case of a memory access, a portion of the address is decoded to select one of a matrix of AND gates which also receives a corresponding bit from one of the file protect registers to produce a signal indicating whether the address is protected or not. An access involving alteration of stored data (or any access) to a protected address is a prohibited action. Other prohibited actions arise on (a) detection of parity error in data accessed from memory, (b) attempted access to a non-existent address, (c) a command only allowable from a particular (variable) processor coming from another processor, or coming from the right processor but when the latter is in the wrong mode. Any prohibited action causes a code identifying it to be sent to all sub-systems and a pulse to be sent to the selected sub-system, the pulse causing the latter to respond to the code by repeating the request, stopping and registering the prohibited action, or signalling the prohibited action and continuing with other processing.

A reagent for use in removing organic sulphur compounds from gases is prepared by washing the "red mud" obtained by melting bauxite with soda in the manufacture of aluminium hydroxide with water to remove soluble salts from the "red mud" to increase the acting surface of the remaining mass. The washing may be continued until the water from the washing is free of dissolved salts. Ammonia or ammonium bi-carbonate may be added to the water, which is preferably distilled water or water which has been treated with an ion exchanger. The washed "red mud" may be used alone or in admixture with sodium carbonate, and at a temperature of 250-300‹ C., and is particularly effective in removing thiopene. It may be used in conjunction with a reagent comprising unwashed "red mud", which is used to remove most of the organic sulphur compounds from the gases to be treated before the gases contact the washed "red mud" reagent. The reagent may be made in granulated form. When inactive after use, it may be reactivated by further washing with water.

The acid may be carboxylic or sulphonic with acrylic acid, methacrylic acid, 2-sulphoethyl methacrylate and 2-acrylamino-2- methyl-propane sulphonic acid being preferred. The poly(vinylidene fluoride) preferably has a melt flow index (the amount of polymer extruded at 250 C. in 1 minute through a 2 mm. nozzle at 10 kg./sq. cm.) of at least 10 at 250 C. The fibres and yarns are prepared by extruding the polymer composition from a solution in an aprotic polar organic solvent as filaments and setting the filaments by a wet, dry or semi-melt method. Films are obtained by forming the same solution into a film and setting by the same methods. The yarns, fibres or films may then be stretched in one or more stages, before or after washing and subsequently heat-treated. The products have good affinity for plastosoluble and cationic dyes. In the Examples, poly(vinylidene fluoride) and copolymers of methylmethacrylate with (1) and (5) 2-acrylamido-2-methyl propane sulphonic acid, (2) and (4) 2-sulphoethyl methacrylate; (3) methacrylic acid, were dissolved in dimethylformaldehyde, extruded into filaments and dyed.

Abstract: 679,026. Turbine plant. PAUKER, F. Sept. 26, 1949 [Aug. 11, 1943; Nov. 17, 1943; May 5, 1944], Nos. 24705/49, 24706/49 and 247 07/49. Class 110(iii) [Also in Group XII] A plant comprising a combination of gas and steam turbines is provided with extra air to cool the combustion gases before the resultant mixture enters the gas turbine, and the exhaust gases from the latter are used to generate steam in a boiler surrounding the steam turbine for the latter. Cooling air and fuel may be fed from a hollow shaft 57, Fig. 5, by way of ducts 59 in a rotor 58 and hollow blades 60 to an annular combustion chamber 61. The gases pass through nozzle 70 and mix with air from passages 69 and pass through guide and moving blades 67, 60 to the steam generator. The firing means 66 may be used only for starting up or continuously. In a second arrangement, Fig. 4, a compressor 1a supplies combustion air and cooling air to a central combustion chamber 5a which feeds gas turbines 2a, 3a, and the exhaust gases plus the warmed cooling air are then led to the steam generator for the steam turbine (not shown). The compressor and turbines are arranged on a common shaft. The burner 6a for the combustion chamber is annular and supplied with compressed air through nozzles 7a arranged peripherally on both sides of the burner. Additional air is supplied to the combustion chamber, after cooling various parts, through inlets 8a. Part of this air flows through a duct 10a to cool parts of the turbine 3a. One air cooling stream is branched off at 17 to pass through a duct 19 around the exhaust gas collecting chamber 12a. The air stream then flows to the hub of the impeller 22 upwards through a chamber 21 on the impeller, through the hollow blades 23 to join the exhaust gas stream. A further air current 24 is led through a channel 26 and is divided into streams 25, 27, the former feeding the inlets 8a. Part of the stream 27 flows radially inwards through hollow guide blades 30. Some warmed air passes down ducts 31 to supply nozzle 7a. In Fig. 7 automatic control means are supplied to maintain constant the gas temperature (through the fuel inlet) and to maintain constant the steam temperature by varying the feed-water admission to the steam boiler. A gas turbine 71 is supplied with fuel by a tank 72 and drives an air compressor 73. The steam turbine 76 is jacketed by a boiler 75 and is connected to a condenser 77. A temperature control device 78 is heated by exhaust gases from the turbine 71 to control a fuel pump 86 which feeds the fuel tank 72. A similar device 79 controls the boiler feed pump 81 which conveys water from the condenser 77 to the boiler 75. The device 79 may vary the pump speed or adjust a valve position. For starting purposes, an auxiliary blower may supply hot air through the stationary gas turbine to generate steam in the boiler to start up the steam turbine.
