Title: Improvements in and relating to electric brakes
IPC: H02K49/04
Filed: 1948-02-25
Abstract: 646,853. Eddy current brake. SOC. ELECTRO-MECANIQUE DE L'AVEYRON. Feb. 25, 1948, No. 5614. Convention date, Feb. 28, 1947. [Class 103 (i)] An eddy current brake of the type having a rotor with groups of electromagnets located on either side is provided with a cooling system that comprises two separate cooling fluid streams, one of which cools the rotor and the other the bearings. As shown in Fig. 3, air supplied from a single fan 21 enters the manifolds 23 and then divides into two streams. One stream passes through axial passages in the electromagnets 25, on to either side of the rotor 1 and out at ports 13a in the cylindrical casing of the brake. The other stream passes through ports 26 in the end-plates and is deflected by a partition 28 on to the ends of the shaft 2 and bearings 3 and escapes through ports 29. Modifications are described in which (a) the cooling stream enters the casing near the periphery of disc 1 dividing into two streams within the casing, and (b) the cooling stream for the bearings is entirely separate from that for the coils and rotor and passes through the brake axially. Relays may be used to connect the circuits to the motor for the cooling fan and the inductor windings to ensure safe operation of the brake.

Title: Improvements relating to internal combustion engines using pulverized solid fuel
IPC: F02B45/02
Filed: 1938-02-23
Abstract: 512,936. Pulverized-fuel engines. BUELL COMBUSTION CO., Ltd., and FRASER, R. P. Feb. 23, 1938, No. 5746. [Class 7 (ii)] In a compression-ignition engine, using pulverized solid fuel, a heat-resistant element is arranged between the combustion chamber and the cylinder space and is insulated from their walls by being supported.by thin flutings which provide passages between the combustion chamber and the cylinder space. The interior of the combustion chamber. is so shaped that an inwardly rotating toroidal vortex of air is produced at the end of the compression stroke and the fuel which is injected centrally is subjected to thermal radiation from the heat-resistant element. In the four-stroke engine shown in Fig. 1, the combustion chamber 4 contains an air inlet valve 5 and an exhaust valve 6 and communicates with the cylinder space through passages 8 between flutings on a heat-insulated block 7 of refractory or heat-resistant material. The upper part of the chamber is shaped to form part of a torus in which the air rotates at the end of the compression stroke. Coal particles, the average diameter of which does not exceed 10 microns, are injected through an inlet 11 controlled by a valve 9. The block may be made of heat-resisting steel which may be coated with zircon or alumina or may be made of steel aluminised by spraying at a high temperature. At starting light fuel may be injected into the chamber or the block may be heated electrically. In the two-stroke engine shown in Fig. 3 the block 18 is connected by webs to a plug 19 which is separated by air spaces from the combustion chamber 27 and the cylinder. The lower part of the block is concave and fits into a recess 30 in the piston 17 at the end of the compression stroke. The pulverized fuel is blown by compressed air from a chamber 31 into the chamber 27 past a valve 33. A liquid-fuel injector 34 is used at starting.

Abstract: 217,279. Lefebure, V. March 5, 1923. Coneretes etc.; plastic compositions containing india-rubber and cement, plaster, etc.; later, treating.-India-rubber is added to cement, plaster, concrete &c. in such quantities and in such a condition as to fill or partly fill the interstices of the cement &c., and not interfere with the setting properties thereof. The rubber must be in a finely-divided state and may be produced by coagulating latex, for example, with alum, or by precipitating rubber from latex on an inert filler such as silica gel or kieselguhr. The latex containing finely divided coagulum may be added to dry cement, or cement paste, or it (or untreated latex) may be made into a paste with a filler which is added to the cement &c. Vulcanizing agents may be added and the rubber vulcanized at any stage, preferably between the initial and final sets of the cement. According to an example, 480 parts of latex are diluted with 150 parts of water, and 160 parts of " colloidal sulphur " (containing 80 parts by weight of sulphur) are added. 400 parts of a 10 per cent solution of alum are added, and sufficient of the mixture to contain 1-5 per cent of rubber of the weight of cement is diluted with water to give about 20 per cent water on the weight of cement. This is added to the cement, and additional water is added as required. The mass is allowed to set and vulcanized, preferably after several weeks. Specification 191,474 is referred to.

Abstract: 116,883. Benjamin Electric Ltd., (Assignees of Benjamin, R. B.). June 18, 1917, [Convention date]. Road traffic signals on vehicles.- A signalling device for motor-vehicles comprises a lamp on each rear mudguard visible from both front and back, and adapted to be lit, one or the other according to the direction in which the vehicle is to turn. The lamps are electric, and the mechanism for operating them consists of the switch shown in Fig. 5, by means of which the desired lamp may be manually lit prior to making the turn, and on making the turn the steering gear operates to maintain the lamp lit and simultaneously releases the manual operating means to allow it to return to neutral position, the lamp eventually being extinguished when the steering gear comes back to the straight course position. The manually operable means consists of a handle 19 fixed on a shaft 39 which carries an arm 41 by which contact is made, through a U-spring 42, with one of two projections 36 connected to terminals 33. The handle 19 and arm 41 are held in their " make " positions by a spring-pressed bolt 45 engaging one of two depressions 44 in an extension 43 of the arm 41, but when the bolt 45 is retracted are brought to the " break " position by a coiled spring 49. The means for retracting the bolt 45 consist of an arm 20 pivoted on the shaft 39 and actuated by a flexible wire connexion from the steering gear to make contact through a U-spring 61 with one or other of the projections 36, at the same time withdrawing the bolt 45 by means of a cam 63 on an extension 62 of the arm 20. Neglect to operate the handle 19 will not prevent lighting of the lamps by the steering gear on making the turn. The rear of each lamp may show an indicating arrow, and the front is so arranged as to illuminate the running boards and door latches. Each lamp comprises an outside casing with a reflector mounted within, both casing and reflector having an opening in the rear. A glass plate carrying the indicating arrow is fixed across the openings.

Class 142(2). As a fresh shuttle 81 is being carried from a magazine 22 by feeder arms 21 to meet the advancing slay, the front and rear walls 62, 64 of the shuttle box are raised to permit the fresh shuttle to enter the box and push out the spent shuttle 82. Movement of the feeder arms about their pivot 25 causes an arm 28, link 30 and arm 32 to lower a roller 42 into the path of a cam lever 74 pivoted on the slay and coupled to the shuttle box walls by an arm 68 and link 66. The cam lever has a surface 76 by which the walls are raised, a surface 78 which keeps them raised, and a surface 80 which allows them to descend to embrace the fresh shuttle 81 so that the feeder arms 21 ride off the points of the shuttle as the slay recedes; the roller 42 is carried by a arm 40 which swings away from a stop 46 so that the roller 42 rides idly over the surface 78 in this direction.
