Title: Improvements in steering arrangements for power-driven vehicles
IPC: B62D7/00
Filed: 1934-01-18
Abstract: 426,828. Motor-vehicle steering-gear. PORSCHE GES., DR. ING. H.C.F., 24, Kronenstrasse, Stuttgart, Germany. Jan. 18, 1934, No. 1864. Convention date, Jan. 18, 1933. [Class 79 (v)] In a vehicle having independentlysprung steering-wheels 1 which swing parallel or approximately parallel to the longitudinal axis of the vehicle and are guided by jointed parallelograms or quadrilaterals and divided track rods 11, 11<1>, the length (a) of the projection of each track rod on the plane in which the wheel normally swings is equal or approximately equal to the length of the projections of the wheel-mounting levers 4, 4<a> on the same plane. In the construction shown in Figs. 1 and 2, the stub axles 2 and steering pivots 3 are connected to the chassis frame by parallel arms 4, 4a pivoted at 7, 8 on the frame. The stub axles are steered by arms 9, 9<1> fixed to the steering pivots and connected by track rods 11, 11<1> to a steering lever 13 rotatable on an axis 14 on the frame and driven from the usual steering shaft 17 through gearing 16. The lever 13 is equal to the arms 9, 9<1>, and the projection (a) of each track-rod on the normal plane of its wheel is equal to the length of each arm 4, 4<a>, so that movements of the arms 4, 4<a> due to the yielding of the suspension springs, (not shown), do not affect the steering angles of the wheels. In this construction the steering wheels always remain parallel to each other so that some slipping of the wheels takes place during steering. In the construction shown in Fig. 3 the arms 9, 9<1> are inwardly directed and are connected by track rods 11, 11<1> to levers 13, 13<1> connected together by a link 18. The lever 13 is rotated by the usual steering shaft 17. Each lever 13, 13<1> is equal and parallel to its arm 9, 9<1>, and the central quadrilateral 13, 13<1>, 18 is arranged to steer the wheels correctly. As in the first construction, the projections of the track rods 11, 11<1>, and the arms 4, 4<a> on the plane in which the wheel swings are each equal to a. Modifications are described in which (1) the steering pivots 3 and the line joining the pivots 7, 8 of the arms 4, 4<a> are inclined to the vertical ; (2) the quadrilateral 13, 13<1>, 18 shown in Fig. 3 is replaced by a single lever 13 pivoted away from the centre line of the vehicle and having two spaced pivots at its outer end by which it is connected to two unequal track rods ; and (3) two equal track rods are connected at their inner ends to a rack sliding transversely of the vehicle and actuated by a pinion on the steering shaft, the projection of one track rod on its wheel plane being increased when the wheels are steered while the projection of the other track rod is diminished.

Title: Driving Mechanism for Producing Intermittent Rotational Movement
IPC: G03B1/38
Filed: 1967-01-13
Abstract: 1,177,123. Variable drive mechanism for a cinematograph. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Jan. 13, 1967, No. 1881/67. Heading G2E. A driving mechanism for intermittently rotating movements in e.g. a film projector, comprises a disc having an axially projecting eccentric pin fixedly mounted thereon, which pin drives a Geneva wheel, the disc being mounted on a constantly rotating shaft, and being axially slidable thereon to interrupt the pin and Geneva wheel connection under the action of a cam and cam follower, dependant on the position of a locking element, operated by a magnet and an armature controlled by electric pulses. As shown in Fig. 1 the cam follower 8 is mounted on an axially slidable shaft 7 to engage with a cam 9 in the disc 1, biased to the right (as shown) to engage the pin 3 and Geneva wheel 5 on each revolution of the disc 1. In the inactive state of the magnet 14 an armature 11 thereon engages a slot in the shaft 7 to prevent axial movement thereof, thereby causing the disc 1 to move against its bias 6, under the action of the cam 9 so that the pin 3 and Geneva wheel do not engage. On activating the electromagnet 14, the armature 11 is withdrawn and the shaft 7, rather than the disc 1, slides so that the pin 3 and wheel 5 may engage. The disc carries a cam (16) arranged to push the armature towards the electromagnet, thereby minimizing the current which must be applied to the latter. In an alternative embodiment Fig. 3 (not shown), a cam pin (31) on a sleeve arranged to move laterally with the hub of the disc (1) acts on a cam path (32) to move the pin (3) into engagement with the Geneva wheel (5) and the locking member acts on a shoulder of the sleeve.

Abstract: 1,139,897. Making dispersion hardened alloys. JOHNSON, MATTHEY & CO. Ltd. Jan. 14, 1966 [Jan. 15, 1965], No. 1882/65. Heading C7D. Dispersion hardened alloys are made by alloying Pd with a minor amount (e. g. 0À2%) of Cr or Rh or Pt, optionally containing at least one other platinum group metal with a minor amount (e. g. up to 1%) of Be, Mg, Al, Si, Th, U, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Sr, Y, Zr, Nb, Mo, Ba, Hf, Ta or a rare earth metal, and heating the alloy in the presence of a gas which forms a stable refractory compound with the additional metal. The gas may be air or oxygen (when the alloy is heated to 900-1400‹ C.) to form dispersed oxide, nitrogen to form a nitride or a carburizing gas such as ethane or ethylene to form a carbide. The refractory compound may also be silicide, boride or sulphide when a suitable gas is used. In the case of Pt containing alloys the gas treatment may preferably be carried out on the powdered alloy, and the massive alloy is reconstituted by powder metallurgical techniques.

Title: Method of and apparatus for progressively heating metal strip by the direct passage of an electric current therethrough
IPC: H05B3/00
Filed: 1958-01-21
Abstract: 833,388. Heating metal strip by passage of current. DEUTSCHE EDELSTAHLWERKE A. G., and ALLGEMEINE ELEKTRICITATS-G.m.b.H. Jan. 21, 1958 [Jan. 22, 1957], No. 2089/58. Class 39(3) [Also in Group XXXV] In heating metal strip especially tinned strip by passage therethrough of current, the strip travels in a zig-zag path over rollers, one group u comprising four juxtaposed rollers, of which S, T are connected each to a separate phase of a seconddary 8 of a high current three-phase transformer, the two outer rollers T being electrically interconnected for connection to the third phase. The supply conductor 3 to the outer rollers T encloses the conductors 4 to the inner rollers. The group of rollers 2 to which current is not supplied and over which the strip also passes, are arranged so that the paths of travelling strip are parallel and are in closely adjacent pairs 5. Supplementary rubber rollers 6 increase the area of contact of the strip with the rollers R, S, T. Boxes 7 of heat insulating material enclose the strip where the paths 5 are closely adjacent, the boxes having metal linings electrically interconnected and connected by a conductor 9 to the star point of the secondary of the transformer. The rollers 2 have a temperature resistant rubber casing with a coating of silicone to reduce slippage of the strip when these rollers are used as driving rollers and are rotated by one roller. The strip may however be driven through the rollers R, S, T to which current is supplied by brushes 17 to sliprings 10 on the roller shaft 11. Each roller may be driven by a separate motor 13 through a flexible coupling 14, the driving member of which carries an arm 15, and the driven member a co-operating arm 16. A wiper on the arm 16 slides on a resistor on the arm 15 so that the relative angles of the arms 15, 16 ensure through the resistance control of the motor maintenance of constant torque. Instead of a resistor, a capacitive or inductive control may be used. The flexible coupling may however be replaced by constructing a roller with an elastic filling 19 between the shaft 11 and an outer metal part 18. Current is supplied by flexible feeding strips to the shaft 11 and to the outer part 18, and the angular position between arms mounted on parts 11, 18 is again used to control the transmitted torque. The rubber filling 19 minimizes loss of heat from the strip to the roller. The metal part 19 of the roller may partly heat the strip and the hollow shaft 4 may be water-cooled.

Abstract: 1,000,179. Circuits employing light sensitive elements. INSTITUTE MATEMATIKI SIBIRSKOGO OTDELINIJA AN U. S. S. R. Jan. 17, 1964, No. 2131/64. Heading G1A. A multistable circuit comprises a Kerr cell 3 between a crossed polariser 2 and analyser 4 the transmitted light through which from a source 1 falls on a photo-resistor 5 to control the voltage across the plates of the Kerr cell. For an increasing voltage applied to the Kerr cell the intensity of light transmitted by the analyser 4 cycles between zero and a maximum value as shown in Fig. 1. In the circuit of Fig. 2 with no light on photoresistor 5 the voltage across the cell is negligible and transmitted light from analyser 4 is zero. If a light pulse is applied to the photoresistor, or a voltage pulse is applied to the Kerr cell, the transmitted light produces voltage across the cell by varying the resistance of the photoresistor. The transmitted light therefore increases beyond a maximum and decreases until a position of stability is reached. A further pulse causes the transmitted light to decrease but carries it into its second region of increasing brightness from which a further stable state is reached. The Kerr cell preferably employs a colloidal solution of bentonite.

Title: Improvements in and relating to systems for the automatic collection of payment for services supplied
IPC: G07F15/00
Filed: 1941-02-18
Abstract: 546,211. Coin-freed meters. SCHILLER, P. Feb. 18, 1941, Nos. 2197 and 7016. [Class 27] Commodities such as electricity, gas, steam, water, &c. are supplied by coin freed meters having means allowing of payment at predetermined times, say, once a week. A dial indicates the outstanding charge for commodity consumed during the time interval on hand, and unless this is eliminated by insertion of more coins the supply is automatically cut off at the termination of the interval, or at the end of a period of grace, if such is allowed, this being effected either by electric remote control or by clock mechanism. Periodically and automatically during the interval an impulse may be sent through the device whereby the supply is stopped should the payment become in arrear, but prepayment may be made at any time. Further, payment for other charges, such as meter rent, may be combined with the commodity payment. Fig. 1 shows an electric two-part tariff prepayment meter 1 and an electric remote control resonance relay 2. The prepayment mechanism operates a switch 7 which controls a bye-pass to the operating coil 8 of an electricallyoperated circuit breaker the break member 9 of which serves to cut off the supply. A contact 10 in a second bye-pass to the coil 8 leads to a normally closed thermostatic contact 12 operated by a bimetallic strip 13 having a heater coil 14 which is energised through a tuned reed 15 co-operating with a contact 16 and magnetised by a coil 17 in series with a condenser 18. On insertion of prepayment coins the switch 7 is closed, and on exhaustion is opened. The supply will not be stopped, however, unless contact 12 is also open. At the predetermined time a ripple signal is sent to vibrate the reed 15 to make contact with 16 and energise the heater 14. Fig. 2 shows means for periodic collection of instalments of a fixed charge in addition to consumption charge. The coin-mechanism actuates a sun wheel 22 of a differential the other sun wheel 24 of which is driven from a spindle 27 carrying a sun wheel 30 of a second differential driven by a meter pinion 33. The sun wheel 30 is driven at constant speed by gearing 32, 34 from a clock 40 furnished with a pointer 91 revolving say, once a week, and a setting pointer 92 determining the time of operation. The sun wheel 24 is on a shaft 36 geared through an idler pinion 41 to a shaft 43 carrying a screw thread 53 and two cylindrical surfaces 51d, 61c joined by a step-up surface 52 and forming an accounting cam. On the surfaces 51d, 51c bear the ends of spring- biased levers 60, 75 pivoted at 61 and controlled by a cam 86 rotated by the clock 40. The accounting lever 60 co-operates with a superposed trip lever governing the supply. A spring-pressed nut 54 rides on the screw 53 to move the surfaces 51d, 51c axially. The outstanding charge pointer is shown at 49.
