Title: Improvements in or relating to steering gear more especially to steering gear for motor road vehicles
IPC: B62D3/02
Filed: 1928-05-14
Abstract: 317,383. Hague, F. H. May 14, 1928. Steering-gear for motor vehicles and motor boats comprises a steering handwheel cam, a fixed disc and a steering- shaft disc, tracks in the said cam and discs and a member slidably and simultaneously engaging the said tracks. The steering hand-wheel shaft 7<1> carries a disc 11 having a spiral slot 12 extending over about 360. A pin 13 provided with coned rollers 14 passes through the slot and also through (a) cam siots 10 in discs 6 fixed to the steering shaft 7, and (b) oppositely-inclined cam slots 5 in fixed discs 2 carried bv the steering column 1, or other fixed part. Thus, when the disc 11 is rotated by the hand-wheel the pin 13 travels along the fixed slots 5 and the movable slots 10 and causes the disc 6 to rotate from A to B. The discs 2 are connected together by bolts 4, and the discs 6 by castellations 9. The cam slots may be so designed that any desirable reduction ratio is given, and the ratio may be larger in the central position of the gear than at the ends, so that when the steering wheels are straight ahead a large movement of the hand-wheel causes a relatively small movement of the steering shaft.

Filed: 1919-06-04
Abstract: 153,345. White, A. E., (Servidor Co.). June 4, 1919. ' Engaged ' and like indicators.-A receiving and delivery cabinet for use on doors, walls, &c. comprises one or more compartments 7, Fig. 2, each having doors 19 giving access to the compartment from both sides of the door &c., and each door being provided with locks 27, 27', Figs. 4 and 6, interlocking with a longitudinally movable detent 50, which, when operated to release a lock of one of the doors. maintains the opposite door in the locked condition while the door last locked cannot be reopened until the other door has been opened and locked. The interlocking-detent is adapted to operate at each door a pivoted target 66, which bears a suitable legend and is adapted to move to and from a position in front of a fixed sign plate 65' bearing a different legend and disposed behind a window 64 vertically arranged in the corner member 14 or 14' of the cabinet. The legend on the fixed sign plate at one side of the compartment is the same as that on the pivoted target at the opposite side, and when the detent is moved' by the advancing bolt, the end of the slide bar at that side of the compartment engages a finger 72 on the target 66 and moves the target, against the action of a spring 71, in front of the plate 65<1> to exhibit the sign " taken," while the opposite receding end of the slide bar allows the spring 71 to throw the pivoted target back and expose the fixed sign " taken." On opening the door at the unlocked side and re-locking the same, both signals will show the sign " vacant " and the doorfirst locked can then be unlocked. In a modification in which one or more of the compartments are used as outgoing compartments only and the others as ingoing compartments, the interlocking-mechanism for the outgoing compartments permits the door last locked to be reopened any number of times without the opposite door being unlocked; in this case, the detent projects into the slot of each lock bolt simultaneously and the slide bar is provided with a lost motion so that the signal targets are not altered by successive openings of one door.

Abstract: 1,014,990. Semi-conductor devices. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. April 8, 1964 [April 11, 1963], No. 14486/64. Heading H1K. A semi-conductor device is made by locating a wire in a groove in a holder and removing any wire extending beyond the ends of the groove, alloying the wire in the groove to a semiconductor body by heating it in contact therewith and finally removing the holder. For instance a plurality of transistors are simultaneously made by first winding lead antimony wires 21 (Fig. 4) about a holder 16 and forcing a rubber block against the top face of the holder to break off the wire between the various sets of grooves and press the remaining wire firmly into the grooves. A jig member 5 (Fig. 7) with a plurality of bores each overlying a set 20 of grooves and extending into one of several slots mating with ridges 15 on the holder is mounted over the holder with a germanium disc in each bore and the discs pressed down by weights 17. The jig parts are aligned by engagement of projections 25 with bores 26. Each disc consists of a P-type core with an antimony diffused N-type skin. After briefly heating to alloy on the wires the jig is dismantled, the middle alloyed strip on each disc coated with aluminium paint and after overcoating the strips with a suspension of alumina in ethanol the wafers are reheated briefly to form diffused extensions of the N-type skin below all three strips and an alloyed PN emitter junction under the middle strip. After alloying indium through the skin on the back of the wafer to form a collector contact the device is mounted on a header and after connection to the terminal pins thereof is shaped by electrolytic etching while the area around the three strips is masked with lacquer.

Title: Method of carrying out exothermic reactions
IPC: C01B21/26
Filed: 1962-04-18
Abstract: 955,417. Exothermic gas reactions. HOUILLERES DU BASSIN DU NORD ET DU PAS-DE-CALAIS. April 18, 1962 [April. 28, 1961], No. 15043/62. Headings B1F and B1X. Exothermic gas reactions are carried out adiabatically by supplying the reaction-mixture to the reaction zone at a temperature at which the reaction-rate is too slow for the reaction to be self-supporting, and maintaining the massvelocity sufficiently low (values from 0À0025- 0.02 gm./cm.<SP>2</SP>/second are specified) to ensure that, before entry into the reaction zone, the reaction-mixture is preheated by convection and radiation of heat from the reaction zone to a temperature at which the reaction is selfsupporting. In Fig. 1, the reaction zones R 1  and R 2  comprise two thin layers of granular material, which may be catalytic or not. The ratio of thickness to surface area of these layers is preferably from 1À5-15 cm./cm.<SP>2</SP>. The reactants, entering at E at the temperature T 0 , flow into the space between the two zones where, because of the relatively large crosssection, they remain sufficiently long to acquire, by thermal retrodiffusion, the temperature Ti at which the reaction becomes self-supporting. The reactants then pass through the zones R 1  and R 2  where the reaction takes place. Since some of the reaction-heat is transferred out of R 1  and R 2  in order to heat the reactants from T 0  to T 1 , the exit temperature T 2  of the products leaving at S is below the permissible maximum temperature, i.e. the temperature at which thermal decomposition of the products or the granular material occurs. Fig. 2 shows an apparatus wherein the reactants are distributed into four admission chambers C 1 , C 2 , Cs, C 4 , each bounded by a reaction zone R ; and there are four withdrawal chambers Si, S 2 , Ss, S 4 , leading to a common exit S. The oxidation of ammonia to nitric oxide on platinum gauze, and the dehydrogenation of methanol to formaldehyde on silver, are mentioned.
