Title: A porous electrode for galvanic accumulator elements and a method of producing such electrode
IPC: H01M4/80
Filed: 1948-12-06
Abstract: 653,235. Accumulators. VOGT, H. Dec. 6, 1948, No. 31513. Convention date, Dec. 15, 1947. Drawings to Specification. [Class 53] An accumulator electrode consists of a porous mass forming a supporting skeleton and made by a sintering process, the pores being filled with a second sintered porous material which is impregnated with the active material such as the hydroxide of iron, nickel or cadmium. The supporting skeleton may be made of metal, carbon or ceramic material, the porous filling material being obtained by impregnating the supporting skeleton with metal salts or an emulsion of metal powder or oxide which on heating are converted into the form of a metal sponge. Instead of a metal filling finely divided carbon may be used. If the supporting skeleton is made of glass, silica or ceramic material such as aluminium oxide it is provided with a surface coating of thin metal by impregnating it with a metal salt and heating. In an example, the supporting skeleton is made by mixing iron powder with particles of charcoal or cellulose fibres, compressing the mixture and sintering it for several hours at 1000 C. When cooled it is impregnated with a metal salt and the whole heated in a reducing atmosphere to form a metal sponge within the pores of the iron skeleton. Hydroxide of nickel or cadmium is then precipitated in the porous mass in known manner. In a modified process the supporting skeleton is made from sintered nickel or steel wool and the pores filled with a thick emulsion of metal or metal oxide with water or acid and the whole dried and sintered. The active material is subsequently introduced into the cooled porous mass. In another example, a porous carbon body is filled with a mixture of soot and tar or pitch and a hydrocarbon such as petrol, benzene or acetone. The liquid is driven off by heat and the carbon particles in the pores lightly sintered at 800-1000 C. in an atmosphere free from oxygen. After cooling, the body is impregnated in the usual way with a metal hydroxide forming the active material. To improve the conductivity of the carbon body its pore surface may be provided with a metal coating by a galvanic or other process. In another example, a porous skeleton of glass or stone is impregnated under vacuum with a nickel salt solution and heated in a reducing atmosphere to form a nickel coating over its whole surface. It is then repeatedly dipped in a solution of nickel nitrate and heated till the pores are filled with nickel oxide. The body is then heated in a reducing atmosphere to covert the oxide into nickel sponge and is then impregnated with cadmium or iron hydroxide to complete the electrode.

Filed: 1939-12-07
Abstract: 534,096. Door latches; seal fastenings. NEWMAN & SONS, Ltd., W., and SHEAD, H. C. Dec. 7, 1939, No. 31666. [Class 44] To prevent operation of the knob of a door latch, except in emergency, a cylindrical casing 21 secured to or integral with the latch casing 1, 2 surrounds the knob 17 with sufficient clearance to allow insertion of the hand, the outer end of the casing being closed by a plate 23 of glass, celluloid, paper or other disruptable material. The device is particularly for use to prevent or discourage the use of public air-raid shelters by unauthorized persons other than when an air-raid warning has been given, but allowing access in emergency by breaking the plate 23. The plate, if of glass, may carry a disc 24 bearing instructions for operation. Plate 23 is retained by the rim 25 of a frame 22 with pins 26 which slide into slots 27 in the casing 21 and are retained between extensions 30 and shoulders 31 of pivoted gravity catches 28. Alternatively, blade spring catches within casing 21 may project through apertures therein into engagement with recesses in frame 22. In either case the catches can only be released when the plate 23 has been broken, the arrangement allowing replacement with a new plate. The knob has a bearing portion 18 and externally square part 16 the end of which is riveted to a retaining plate 20. Part 16 fits into a two-armed follower 15 engaging projections 14 on the bifurcated bolt tail, and has a square aperture receiving the spindle 19 of an inside handle, not shown. The bolt is shot by a spring 4 bearing against one of two projections 5. The bolt may be retracted by an authorized person by means of a key inserted through a keyhole 9, the end of the stem passing through a slot 12 in the bolt into engagement with a bearing aperture 11, the bit of the key, when rotated, engaging one or other of two pins 10 carried by the bolt. The application to a mortise latch is described, the sealing chamber being separate from the latch casing, but screwing thereon when the latter has been fixed in place. The knob casing may contain a low-voltage lamp.

Title: Improvements relating to clutches, particularly for motor vehicles
IPC: F16D23/06
Filed: 1960-09-14
Abstract: 900,436. Friction clutches. DAIMLERBENZ A.G. Sept. 14, 1960 [Sept. 17, 1959], No. 31721/60. Class 80 (2). To balk full engagement of friction surfaces, e.g. frusto-conical surfaces 17, 19, in a clutch until synchronism has been achieved, engagement being produced by sliding a clutch-sleeve 12 axially so that interdigitating studs 13, 14 on the sleeve and a supporting-shaft 10 contact along inclined cam surfaces 16, whereby a torque-responsive clutch-engaging force is produced, a synchronizing ring 18 biased by springs (not shown) towards the clutch sleeve is provided with claws 21 interengaging with claws 20 on an associated gear-wheel 11 or the like and the tips 22, 23 of the claws are inclined, so that on initial engagement of the friction surfaces prior to synchronism relative rotation between the two sets of claws wedges the inclined surfaces on to each other and prevents the clutch-sleeve, 12 from being slidden fully into the engaged position. On synchronism, the claws 20, 21 slide between each other and flats at their ends abut the bottoms of the recesses between the opposing claws. The clutch-sleeve 12 completes its axial sliding movement and the cams 16 on the studs 13, 14 then contact along more steeply-inclined areas of their surfaces, thus giving an increased torque-responsve clutch-engaging force. As shown, the frustoconical surfaces 17, 19 serve both for synchronizing and for establishing clutch engagement, but alternatively separate friction surfaces may be provided. For a clutch used as a main clutch in a motor vehicle, the frusto-conical surfaces 17, 19 may be replaced by plates &c. -Reference has been directed by the Comptroller to Specifications 827,114 and 829,052.

Title: Improved multiple steering systems for vehicles
IPC: B62D7/02
Filed: 1955-11-07
Abstract: 804,836. Motor vehicles. BOBARD, E. Nov. 7, 1955 [Nov. 6, 1954; March 9, 1955; July 4, 1955], No. 31751/55. Classes 79(2), 79(5) and 136(1) In a vehicle the rear wheel assembly can be connected to the steerable front assembly whereby the rear assembly can be steerably rotated in the same or opposite direction to the front assembly. As shown in Fig. 8 single wheels 71 are mounted at the front and rear of the vehicle 1 and are supported by stub axles 70 on brackets 68 which carry sleeves 72 containing shafts 73 connected by gearing within casings 69 with the wheels. The shafts 73 are driven from the motor (not shown) by a shaft 77 connected by bevel gearing 75, 76 to the shafts. The sleeve 72 of the front wheel carries a bevel gear 81 and the sleeve 72 of the rear wheel rotatably carries bevel gears 86, 87, the gears 81, 86, 87 meshing with bevel pinions 82, 85 on a shaft 83 rotated through chain gearing 89 from a steering mechanism (not shown). The gears 86, 87 have apertures 96 to receive a pin 34d carried by a sleeve 90 keyed to the sleeve 72, the pin being vertically displaceable by a handle 93 whereby the sleeve 72 can be locked to either gear 85 or 87. In the position shown in Fig. 8 the pin 34d is disengaged from both gears 86, 87 and hence the rear wheel is not steered but held in a centred position by a finger 92 on the handle 93 engaging a cut-out in a ring 102 on the sleeve 90. The pin 34d is held in its selected position by a spring loaded ball 98 engaging notches 100 in the pin. In a modification, Figs. 3, 4, and 7 (not shown), the wheel pivots are interconnected by a diagonal strut, the connection of the strut to one pivot being releasable and the pivot locked to the frame by a vertically slidable pin. In Fig. 7 the drive to the wheels includes a differential gear which can be locked when the rear wheel is in its centred position. In another embodiment, Figs. 1 and 2 (not shown)., the pivots are interengaged by a crossed chain. The wheel assemblies may each have one or two wheels. In a further embodiment, Figs. 5 and 6 (not shown), the front wheel assembly is positively steered and is connected at a single point to two rods, the other ends of which are releasably connected to diametrically spaced points on the pivot of the rear wheel assembly, the releasabLe connections comprising pins controlled for vertical displacement by a single hand lever.

Inventor: EPSTEIN PETER
IPC: F16K31/40
Filed: 1955-11-07
Abstract: 825,363. Valves. S.E. LABORATORIES Ltd., [formerly MECHANICAL & ELECTRONIC PRODUCTS (LONDON) Ltd.]. Nov. 7, 1956 [Nov. 7, 1955], No. 31802/55. Class 135. A valve has an axially slidable non-magnetic main valve member 50 with a nylon sealing member 52 co-operating with an outlet valve seat 53 and a pilot valve 56 co-operating with a valve seat in the sealing member, the pilot valve being attached to a ferro-magnetic armature 57 which can be moved in the line of action of the main valve under the control of a solenoid 27 towards a magnetic core 40, rigidly secured to the main valve member, to operate the pilot valve, and the magnetic core and main valve member being slidably mounted in a fixed member 16 of a magnetic valve casing so that the core can move together with the movable armature in the line of action of the main valve without appreciably altering the total length of the air gaps in the magnetic circuit of the armature, which circuit is completed by a flanged magnetic member 31 carrying the main valve seat and having four radially spaced axially extending polepieces 36 and soft iron ring 60 mounted circumferentially on the main valve member 50 to concentrate the flux towards the armature 57. The main valve is normally closed by the action of spring 44 and upstream fluid pressure acting in chambers 43, 46 and 47, fluid entering these chambers via the restricted circumferential clearance between the core 40 and the cup-shaped member 16, and radial bores 42 in the core. A spring 48 acts on the pilot valve to keep it closed so as to maintain the fluid pressure in the chambers. When the solenoid is energized the armature 57 is attracted to the core 40, which opens the pilot valve, and allows fluid pressure to escape more freely through the bore 55 in the valve sealing member to the downstream side of the main valve seat than it enters the chambers 43, 46, 47 as described above, the upstream pressure then acting substantially only on the outer parts of the valve member 50 is sufficient to overcome the force of spring 44 to open the main valve. In a modification the pilot valve is arranged to be open when the solenoid is not energized and because of the pressure differences described above the main valve is also open, and when the solenoid is energized the pilot valve is caused to close and consequently the main valve also closes.
