Filed: 1931-05-02
Abstract: 361,809. Lubricating kinematograph apparatus. OEHMICHEN, E. E., 16, Rue de Villers, Valentigney, Doubs, France. May 2, 1931, No. 13002. Convention date, July 25, 1930. [Class 12 (iii).] In kinematographic apparatus wherein the film I is fed through a gate 2, provided with a movable plate 7, by grips 3 operated by a cam 5, oil is supplied to the mechanism through a pipe 14 from a reservoir 8 by means of a feeding member which is operated by the opening or closing movements of the plate 7. As shown in Fig. 1, the oil feeding member comprises a plunger 10 slidable through the wall of the reservoir and provided with a groove 11. When the plate 7 is closed, a spring abutment 13 thereon maintains the plunger in position with the groove 11 within the reservoir, but when the plate is opened a spring 12 moves the plunger to bring the groove outside the reservoir, and the oil in the groove falls into the pipe 14. Packing rings may be fitted on the plunger to prevent leakage..The plunger may be rendered inoperative by means of a pivoted stop 19 or by removing the abutment 13 so as to uncover an aperture 18 in the plate 7. As shown in Fig. 4, a spring-pressed double valve 23, 24 is operated by a cam 29 on a spring-pressed rod 25 co-operating with the plate 7 so as to deliver a measured quantity of oil to the pipe 14 each time the plate 7 is opened. As shown in Fig. 5, a spoon 30 pivoted on the reservoir has an arm 32 contacting with a spring- pressed rod 33 co-operating with the plate 7 whereby when the latter is closed the spoon is lifted to deliver oil into the pipe 14.

Abstract: 289,837. British Thomson-Houston Co., Ltd., (Assignees of Shaw, G. R., and Tellkamp, B. F.). May 3, 1927, [Convention date]. Vacuum tubes.-In the treatment of metal filaments by exposure while incandescent to a gas containing carbon or other non-metal, the duration of the exposure is controlled by the increase in resistance of the filaments, and means are provided to prevent the filaments from being heated outside the gas chamber. The filament mounts are supported by their exhaust tubes in holders 26, shown in plan in Fig. 3, adapted to be raised and lowered on vertical posts 12 by pedal action to bring the filaments into and out of gas chambers 35, the parts being duplicated to enable one filament mount to be inserted while another is being treated. The leading-in wires of the mounts are inserted in clips 27, 28 connected to the current supply. Current is switched on to the filaments by a lever 52 pivoted at 56, and the sliding brackets 49 of the mount holders 26 are provided with interlocks coacting with an interlock bar 55. carried by the lever 52 to permit current to be switched on only when a filament is in a chamber 35. The main switches 57, 62 are closed by the lever 52 through springs 59 which retract it when it is released, during which action a controlling circuit is closed and again broken by fingers 65 on the lever bridging and leaving contacts 63, 64. Current is supplied to the filaments 19, Fig. 5, by a constant-current transformer 86 controlled by an induction regulator 81. When the fingers 65 close the controlling circuit, a magnetic relay 84 closes the primary circuit of the transformer 86, and when the controlling circuit is again broken a. resistor 90 allows sufficient current to pass to keep the relay switch 84 closed, although this current is insufficient to close it initially. Constant current being maintained through the filaments 19 the voltage across them increases as their resistance rises. This voltage is impressed on the grid 97 of a three electrode thermionic valve. A predetermined negative bias is applied to this grid by a battery C and a potentiometer 102. When the potential on the grid becomes positive owing to a filament 19 having absorbed a predetermined amount of the non-metal, grid current flows and operates a relay 96 which closes a circuit through a relay 100 from a point 101 of the potentiometer. This reduces the grid bias applied to the valve and thus increases the grid current operating the relay 96. The relay 100 breaks the circuit of the transformer 86, thus terminating the treatment of the filament. A mixture of benzol and hydrogen may be supplied to the chambers 35 by the apparatus shown in Fig. 4. Benzol is forced to a desired height in a mixing chamber 68 by the pressure of hydrogen acting through a pipe 71 and controlling valve 72. Hydrogen passing by a pipe 74 and controlled by a valve 76 carries benzol vapour into the chamber 35.

Title: Improvements relating to the production of volatilisable products from coal and oil and to the production of gas by heat treatment of carbonaceous materials
IPC: C10B55/02
Filed: 1930-04-29
Abstract: A petroleum hydrocarbon heavier than gasolene, for example gas oil, together with powdered coal is passed through a long (500 feet) pipe of small diameter (2 inches) heated to a temperature not exceeding 1100 DEG  F., this temperature being controlled to give either low temperature distillates, light hydrocarbons, and benzol, or gas. Steam or inert gases may be introduced, or the liquid hydrocarbon may serve as a carrier.  The coal is ground so that at least 85 per cent passes a 200 mesh sieve, but finer grinding is preferable. Atmospheric pressure may be used, but p  75-100 pounds per square inch hastens the operation.  The powdered coal and hydrocarbons may be emulsified with water, preheated, and injected into the coil. Catalysts to assist the reaction are used to line the tube, copper, cobalt, nickel, chromium, tin, or ferrosilicon being suitable; or colloidal metals may be introduced into the coal-oil mixture.

IPC: G05F1/34
Filed: 1952-05-23
Abstract: 743,524. Automatic voltage control systems. PHILIPS ELECTRICAL INDUSTRIES, Ltd. May 15, 1953 [May 23,1952], No. 13201/52. Class 38 (4). [Also in Group XXXVI] The output voltage of a transformer of the type having a primary winding connected to the A.C. supply, a core part which is saturable, and a core part which is unsaturated under operating conditions, the saturable part carrying a winding across which is connected a condenser; is further regulated by a saturable reactor controlled in accordance with the output voltage and connected in series with the output or in series with the condenser, or in series with both. In one embodiment, Fig. 12, the transformer 3 supplies load terminals 6, 7, the saturable reactor 5 being connected between the winding on the saturable part of the transformer core and the condenser 4. The reactor 5 is controlled by a winding 23 energized by a phase-sensitive amplifier 43, in accordance with the output of a bridge consisting of an indirectly heated thermistor 30, and resistors 31, 32, 33. The bridge is connected across the output 6, 7 via a transformer 70 which also provides heater and bias voltages for the amplifier 43. The heater of the thermistor 30 is supplied from a further winding on transformer 70 from a potential divider consisting of a resistor 36 and a thermistor 35, in order to compensate for changes in the thermistor 30 due to ambient temperature. The bridge output is coupled to the amplifier 43 by a transformer 41, the secondary of which is shunted by a phase-correcting condenser 86, and is in series with a bias voltage tapped off potentiometer 83. The anode is supplied with unsmoothed, half-wave rectified voltage by the rectifier 45, hence the conduction of the valve is determined by the relative phase angle between the anode voltage and the A.C. signal derived from the thermistor bridge, and the reactor 23 is controlled accordingly. Transient negative feedback is provided via condenser 89 from anode to control grid. The rectifier 87 prevents the bridge from being effectively shortcircuited by the grid current of the valve if driven too far positive. The relay R operates on failure of the anode current of valve 43 to reduce the output voltage and at starting increases .the heating current of thermistor 30. In a modification, Fig. 13 (not shown), the input transformer is replaced by a valve amplifier. It is stated that in either system the regulating transformer may have the unsaturated secondary auto-connected with the primary, Fig. 3 (not shown), that the saturable reactor may have an additional D.C. bias winding, Fig. 5 (not shown) which opposes the control field; that the voltage detector may consist of a simple thermistor bridge, Fig. 6 (not shown), and that the phase-sensitive amplifier may consist of a cathode-coupled trigger pair of valves, Fig. 9 (not shown).
