Title: Improvements in and relating to the control device of the engine of an automobile
Filed: 1938-01-27
Abstract: 505,860. Controlling motor vehicles. VAU, J.-B., P. Jan, 27, 1938, No. 2581. Convention date, Jan. 27, 1937. [Class 79 (v)] The slow-running or idling control of the throttle or other engine-speed controlling means is set in either of two positions by 'the handbrake lever, so that (1) when the brake is on and the vehicle stationary the engine idles at a low speed, and (2) when the vehicle is moving and the brake is off the idling speed of the engine is higher, thus making gear-changing easier and lessening the risk of stalling the engine. In the construction shown in Fig. 1 the engine throttle 8 is controlled by the accelerator pedal 1 through a link 5 and an arm 6 fixed on the throttle shaft 7. When the accelerator pedal is released a spring 18 moves the throttle in the closing direction until either a lug 17 on the arm 6 abuts an adjustable stop 19, or a lug 16 on the arm 6 abuts against an arm 9 which is loose on the shaft 7 and is controlled by a spring 12 and a Bowden cable 10 connected to the hand-brake lever 11. When the lever 11 is pulled to apply the brake the arm 9 is pulled away from an adjustable stop 14 and the lug 17 is allowed to abut the stop 19 which determines the slowest running speed of the engine. When the hand-brake lever 11 is released the spring 12 pulls the arm 9 against the stop 14, and the arm 9 then forms an abutment for the lug 16 of the arm 6, so that the throttle cannot close to the position determined by the lug 17 and stop 14, and the engine idles at a higher speed. In a modification the accelerator pedal controls the throttle through a variable ratio device which may be of the kind described in Specification 502,726, and the throttle arms abut against a lever which has two set positions determined by two adjustable stops and is held against one stop or the other by the hand-brake lever and a spring.

Title: Improvements in or relating to vacuum-tight seals for current leads into quartz or refractory glass vessels
IPC: C03C27/02
Filed: 1932-01-30
Abstract: 396,103. Sealing leading-in wires into vitreous envelopes. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Jan. 30, 1932, No. 2889. Convention date, March 13, 1931. [Class 39 (ii).] A vacuum-tight seal for securing electric current conductors into quartz or other refractory glass vessels is effected by using as the conductors refractory metal strips of a maximum thickness of about 20 Á. The metal strips may consist of tantalum, niobium, molybdenum, tungsten, tungsten-molybdenum alloys, &c., and the sealing is effected as far as is. possible, in the absence of hydrogen, for example by a carbon-flame arc, an electric furnace, or by embedding a carbon core in the quartz body and circulating eddy currents therethrough. The metals are also subjected to a preliminary treatment to expel occluded gases by heating them to a high temperature in a vacuum. When the conductor consists of tantalum it is first anodically polarized in normal sulphuric acid with a potential of about 90 volts. In order to protect the foil at the points where it is not sealed into the quartz, its ends may be attached to thicker sheets, for example of molybdenum, by spot welding or clamping. A thermal and mechanical protection for the ends of the strips may also be obtained by sealing them with metals such as lead or bismuth introduced into recesses in the vessel.

Title: Improvements in or relating to electric pulse code transmission devices
Inventor: BLANDE ROBERT GASTON
IPC: H03M1/00
Filed: 1954-02-03
Abstract: 745,979. Pulse code modulation circuits. SOC. ALSACIENNE DE CONSTRUCTIONS MECANIQUES. Feb. 3, 1954 [Feb. 6, 1953], No. 3239/54. Class 40 (5). Relates to the reduction of timing deviations in the code pulse groups produced by a cathoderay tube coder of the type described in Specifications 661,808 and 701,347. The output from the signal source 9, Fig. 1, is converted in circuit 8 to a 'step-wave signal, representing quantized samples of the input wave, under the control of master pulses A, Fig. 2, from a generator 10, occurring during time intervals O. The deflector plates 3 of the coder tube 1 are supplied with the step wave upon which are superposed the sloping portions of a saw-tooth wave from generator 7. The beam is suppiessed during the flyback period by A pulses applied, over lead 10', to the control electrode 2<SP>1</SP> of the tube. The apertured coding electrode 5 modulates the beam to produce on anode 4, groups of five # On-Off " code pulses B occurring during the intervals 1 ... 5. Simultaneously, an apertured electrode 6 produces groups of five reference pulses C whose timing is the same as that of the code pulses. The reference pulses, after removal of the D.C. component in condenser 13<SP>1</SP>, and delay in network 15, are applied to two oppositely-directed diodes 18, 18<SP>1</SP>. The output from diode 18 is phase-reversed, and at points 20, 19, two sets of interlacing reference pulses D, E, respectively, are produced. These are converted into rectangular pulses F, G, in circuits 22, 25 and 21, 23 respectively. Upon these pulses are superposed a pulse H, derived from the A pulses from generator 10 after delay in network 26 and passage through individual buffer stages 30, 29. The combined waves J, K are clipped by stages 34, 31, respectively, at such a level that the H pulse passes only when superposed on a F or G pulse. These pulses are used to set a two-condition trigger circuit 35 to one or other of its stable states depending upon which clipper circuit produces an output pulse, so that only one of the gate valves 51, 51<SP>1</SP> is unblocked to pass code pulses to the pulse shaper 55 and output circuit 56. The gate valves are fed with two versions L, M, of the code pulse groups through cathode followers 49, 50 respectively. These versions have a time displacement of half a pulse period introduced by delay networks 47, 48 to which are fed the code pulse groups from the output electrode 4 of the tube 1. The circuits are so set up that the selected version of the code group is the one which has the lesser deviation from the desired position.
