Title: Improvements relating to fluid pressure brakes for automobiles and the like
IPC: B60T13/46
Filed: 1922-06-08
Abstract: 203,071. Tomlinson, A. V., (Soc. d'Applications Westinghouse aux Automobiles). June 8, 1922. Fluid-pressure. - In a combined straight and automatic system for automobiles, the main reservoir is directly and permanently connected to the automatic pipe and the automatic pipe is connected to the straight air pipe for effecting a straight air application of the brakes; an automatic application being thus effected in the event of leakage of the main reservoir, or, when a straight air application is attempted, of the straight air pipe. The system comprises an automatic pipe 18 connected to the driver's valve 6, to the main reservoir 3 and by way of passages 17, 22, 16 of valves 10, to the auxiliary reservoirs 8. Brake cylinders 5 are normally connected by passage 11, slide valve 20 and passage 13 of the valves 10, with a straight air pipe 15. This pipe can be connected by the driver's valve 6 actuated by a pedal 7, either to atmosphere to exhaust the brake cylinders or to the automatic pipe 18 and thence to the main reservoir 3 to effect a straight air application of the brakes. If, however, the pipe 15 should be injured as by the breakage of the coupling 25 and a straight air application be attempted, the escape of air from the main reservoir and pipe 18 causes the piston 19 of each valve 10 to move to the left to connect the auxiliary reservoirs 8 with the brake cylinders and thus to effect an automatic application of the brakes. Leakage from the main reservoir 3 or from the automatic pipe 18 effects an immediate automatic application of the brakes. Pressure gauges 28 are connected to the main reservoir and to the pipe 15.

Title: Improvements in or relating to electric discharge tubes
IPC: H01J29/28
Filed: 1946-05-28
Abstract: 612,581. Cathode-ray tubes. PHILIPS LAMPS, Ltd. May 28, 1946, No. 16235. Convention date, Jan. 16, 1940. [Class 39 (i)] In a tube having a luminescent screen and also a coating of carbon applied together with an organic material acting as a provisional adhesive, the carbon coating contains one or more inorganic oxides difficultly soluble in water, such as magnesium, calcium, strontium, barium or iron. The oxide acts as a permanent adhesive, preventing carbon particles from leaving the coating and depositing on the luminescent screen, especially where the screen used phosphoric acid as a binder. In one example, graphite is mixed with agar-agar, a small quantity of ammonia, and magnesium or ferrous oxide; or with methyl glycol acetate, nitro-cellulose and magnesium oxide. The oxide may be applied as carbonate and converted by subsequent heating. The subjectmatter is identical with that of Specification 546,584.
Patent GB-409911-A (GB)
Title: Process for the deoxidation and purification of copper
IPC: C22B15/14
Filed: 1933-06-06
Abstract: Copper oxide and other oxidized impurities are removed from copper by violently intermixing the molten metal and a previously molten very fluid slag having a high dissolving power for the oxidized impurities, the reaction being completed in such a short time that no external heating is necessary.  The slag may comprise silica, titanium oxide, alumina, lime, magnesia, alkali or alkaline earth salts, oxides of iron or other metals not reducible by copper, and may be melted down in a water jacketed furnace so as to produce an autolining.  After exhaustion, the slag may be regenerated for further use by reduction, for example by carbon. Violent intermixing is produced by pouring the copper in a thick jet onto the slag in a ladle, by mechanical agitation as by rocking a ladle containing the metal and slag, or by means of a gas.  The Specification as open to inspection under Sect. 91 comprises also agitating the slag and metal by means of an electric field. This subject-matter does not appear in the Specification as accepted.

Filed: 1973-04-05
Abstract: 1417236 Analogue-to-digital conversion SOC ANON FRANCAISE DU FERODO 5 April 1973 [5 April 1972] 16344/73 Heading H3H In a dual ramp analogue-to-digital converter, integrating capacitor 12 becomes charged during a preliminary correction phase A with the integrated drift of the amplifiers 13, 14, which is then subtracted from the integration of the input  Vx during phase B (e.g. by reversing the connections to the capacitor 12) so as to correct the duration Tx of the final discharge of capacitor 12 for said drift. In Figs. 1 and 2 the durations T of phases A and B are each equal to 10<SP>3</SP> clock pulses from oscillator 21, counted in decades 22. At the end of phase B, switch I 3  shorts amplifier 14 and switches I 4  are closed to allow reference current 18 to discharge capacitor 12, comparator 20 triggering read-out of counter 23 at the end of phase C.  Modifications.-A rest period (R 2 ) may be interposed between phases A and B in which amplifier 14 is shorted and capacitor 12 is isolated. An inverting amplifier (30) may replace reversing switches I 5 -I 8 , Fig. 5 (not shown). The reference current may be applied via amplifier 14, a drift correction voltage being applied to the comparator, Figs. 6 and 7 (not shown). Phases A and B need not be of equal duration if appropriate weighting resistors are used. Input Vx may come from a Wheatstone bridge, supplied with D.C. pulses of width equal to the combined duration of phases B and C, switches I 1 , I 2  then being unnecessary. Said D.C. pulses may be derived from the same source (V R ) as the reference current 18, Fig. 8 (not shown).

IPC: H04Q3/00
Filed: 1969-03-28
Abstract: 1,218,902. Automatic exchange systems. SIEMENS A.G. 28 March, 1969 [29 March, 1968], No. 16355/69. Addition to 1,176,514. Heading H4K. In a multi-exchange system in which the number of the called party is transmitted throughout the system until the exchange to which he is connected is found whereafter a path back to the originating exchange is set-up using route identification data supplied by each transit exchange, certain subscribers are allocated to a local exchange, whereby for such subscribers it may be sufficient to transmit initially through the system only the three digits of the local exchange code. When the main exchange, e.g. A, having the wanted local exchange, e.g. ZV1, connected thereto is found, a path back to the calling exchange is set up and the remainder of the wanted number is sent to the local exchange directly. If, however, the wanted number is sent with the local exchange code during initial route finding it can be immediately used, once the correct main exchange is found with the aid of the local code, to determine the free/busy state of the wanted party, whereby undue holding of the backward path is prevented. Certain privileged subscribers, e.g. 111, 112, may have three digit codes so as to allow them to be found more readily. A local exchange, e.g. ZV2, may be subdivided and each subportion ZV2a, ZV2b allotted to a different main exchange D, F. In this case if a call for subscriber ZV2b 999 should reach D before it reaches F, it is immediately rerouted to F with the aid of a routing instruction supplied by ZV2a.

Title: Synchronisation of machines for recording sounds and movements and for reproducing such sounds and movements by phonograph and kinematograph
IPC: G03B31/00
Filed: 1928-06-05
Abstract: 318,847. Verity, C. H. June 5, 1928. Combined working of f gramophones with kinematographs.-To facilitate the regulation of the speed of the electric motor driving a gramophone geared with a kinematograph so that reproduction can be effected in various cinemas at the same pitch as that recorded, a centrifugalball mechanism 29 similar to a governor mechanism is driven by gearing 30 from the sbaft driving the turntable spindle 3 at an increased speed, and its disc acts to move a pivoted pointer 27 over a scale provided with an adjustable indicator 41. A tuning note produced by a standard tuning fork is recorded on the record when it is produced, and a duplicated tuning fork is supplied to the kinema whereby the tuning note reproduced by the record can be caused to correspond with the fork by adjustment of a resistance in the circuit of the driving motor. The indicator 41 is then moved opposite to the finger 27 and marks the position at which the finger must be maintained by adjustment of the resistance in order to maintain reproduction at the correct pitch. The gramophone is connected with the kinematograph 35 by a universal jointed shaft 7 and a clutch 10, 11, the part 10 which is apertured to engage rubber-covered projections on the part 11 being withdrawable against a spring 12 and capable of being locked in disengaged position by a pin 14. The turntable spindle 3 is mounted in a bracket 20 which, together with the bearings 5 for the driving and speed-indicating gear, is supported on a layer of rubber or compressed cork 17 on the top 19 of a pedestal stand 18. The projector and indicator mechanism may be enclosed in a sound-proof cabinet with windows for projection of the picture and for observation of the indicator, and the motor resistance may be mounted on the cabinet. A sighting-tube may permit the operator to see the projected picture on the screen in case the pedestal obstructs this view.

Patent GB-459658-A (GB)
Title: Improvements in tuning systems for radio apparatus
IPC: H03J7/16
Filed: 1935-06-07
Abstract: 459,658. Valve circuits for wireless reception. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. June 7, 1935, No. 16605. Convention date, June 7, 1934. [Class 40 (v)] A manually-tuned wireless receiver is provided with a supplementary automatic tuning device, actuated by the fall in anode current when resonance is approached, to give final accuracy of tuning. Fig. 4 shows a superheterodyne receiver in which the tuning circuits L1A, L2B, L3C, of the high frequency valve V1 and the hexode frequency changer V2 are shunted by auxiliary trimmer condensers a, b, c, constituted by three pairs of vanes a, a<1>, b b<1>, c cl arranged as shown in Fig. 3, for simultaneous adjustment by the moving coil of a galvanometer connected in the anode circuit of any of the valves V1, V2, V3 which are all controlled by the A.V.C. system of the receiver. The arrangement is such that as the anode current begins to fall when resonance is approached by manual tuning, the trimmers are operated by the galvanometer to adjust the receiver to exact resonance. This only occurs on the fall of anode current; on the other side of the exact resonance frequency the effect is to detune rapidly. An alternative arrangement is shown in Fig. 5, in which the tuning inductance L1 of the local oscillator of a superheterodyne receiver is wound on a magnetic core N, which also carries a coil L2 connected in the anode circuit of a valve controlled by the A.V.C. system. A third coil L3 carries a constant direct current equal to the average anode current at resonance of the valve supplying L2. The arrangement is such that the magnetization of the core is zero at exact resonance, the inductance L1 varying as a function of the current in L2 so that as soon as the latter begins to fall the inductance of L1 begins to rise and the effect is cumulative until exact resonance is obtained. Alternatively the current in L2 may vary the coupling between two halves of the coil L1. The anode current of the signal detector may be used to effect the automatic adjustment. As the effective range of automatic control is restricted to a frequency band on one side of the resonant frequency, the receiver may be provided with a special form of dial having indices of a certain length corresponding to that band, Fig. 8 (not shown). Specification 433,298 is referred to. Reference has been directed by the Comptroller to Specifications 181,799, [Class 40 (v)], 360,891, 407,057, 425,626, 437,442, and 452,585.

Abstract: 896,076. Clutch control. DAIMLER-BENZ A.G. May 11, 1960, No. 16624/60. Class 80 (2). In a vehicle transmission including an hydraulic clutch 2 and mechanical disc clutch 3 the operating lever 4 of the latter is under the conjoint control of an electric motor 13 operated by the gear change lever 23, and a suction servomotor motor 30 controlled by the accelerator pedal 44 and an inertia pendulum mass 49. Motor 13 operates lever 4 through a crank 10 and rod 7 incorporating a resilient section 8, while servomotor 30 operates through a rod 28 with a resilient section 32. The motor control switches 16a, 16b are operated by a contact-arm 20 bearing against a motor-driven cam 15 comprising low and high semicircular contour portions. The arrangement is shown in the neutral position and upon putting pressure on the lever 23 contacts 20, 21 are closed, and upon moving the lever a switch 24 is opened and a further switch 52 closed. A relay 18 is opened and a second relay 17 closed to supply current to motor 13 through contact 16a, the motor and crank 10 rotating clockwise and rod 7 moving to the left to operate lever 4 for clutch disengagement. After a half-revolution the clutch is fully disengaged, arm 20 contacting the raised surface of cam 15 so that contacts 16a, 16b are closed and opened respectively, and the motor stopped. Upon release of lever 23 when a gear change is completed, contacts 20, 21 open, relay 18 closes and relay 17 opens and motor 13 makes a second half-revolution, the return movement of rod 7 re-engaging the clutch. The resilient member 8 in rod 7 enables disengagement of the clutch to be effected more slowly than engagement. Servomotor 30 conprises a diaphragm 29 connected to rod 28 and forming a working chamber 33 communicating with a control valve 36 actuated by the accelerator pedal 44 or inertia weight 49. A switch 26 incorporated in the speedometer 27 operates so that current is supplied to gear lever switch 24 only when the vehicle is in motion.
