IPC: F15B21/08
Filed: 1959-05-05
Abstract: 885,534. Regulating. SCHWERMASCHINENBAU K. LIEBKNECHT MAGDEBURG VEB. May 5, 1959, No. 15444/59. Class 7(6). An engine remote control installation comprises a manual control shaft 1 which is hydraulically-movable in either direction by a piston-actuated rack and pinion 4, 5, under the control of solenoid-operated valves 7, 7<SP>1</SP>, which direct air pressure to the surface of fluid in containers 15, 15<SP>1</SP>, of separate hydraulic systems, which are connected to the separate cylinder ends through throttle passages 9, 9<SP>1</SP>, a contact arm 11 being fixed to the control shaft 1 co-operating with fixed contact rails 12, 13, 13<SP>1</SP>, which are connected to a function selecting switch 8 which controls the solenoids 7, 7<SP>1</SP> according to the direction of movement desired; a switch 14 for selective energizing of either solenoid and a power supply switch 16. To start the engine, switch 8 is set as shown in Fig. 1 to energize the solenoid 7, via sliding contact 11, rail 12, to cause compressed air from P to be directed by the valve 6 to the surface of hydraulic fluid in container 15. Fluid pressure, regulated by throttle 9, causes a piston 3 to rotate the control shaft 1, with its attached sliding contact, by means of the rack and pinion 4, 5. During starting, the contact 11 slides along rails 12, 13, until it leaves rail 12 at a predetermined engine speed, to de-energize the solenoid 7, thus causing the valve 6 to block the passage of compressed air from pipe P  and to vent air from tank 15 through aperture 18. Further regulation of engine speed is effected by a two-position switch 14 which in one position energizes solenoid 7 to rotate shaft 1 to increase speed and in another position energizes solenoid 7<SP>1</SP> which in a similar manner decreases speed. Setting of switch 8 into a reverse position (see Fig. 3 not shown) causes the contact 11 to energize solenoid 7<SP>1</SP> to start the engine in a reverse direction in a similar manner to that described for forward direction. Lamps 17, 17<SP>1</SP> are illuminated to indicate operational readiness. A hand wheel 2 manually controls shaft 1, fluid by-passing through conduits 10, 10<SP>1</SP> to containers 15, 15<SP>1</SP>.

Title: Improved means for use in connection with the coating of electrodes of electric discharge devices
IPC: H01J9/06
Filed: 1941-12-01
Abstract: 552,468. Coating electrodes. BRITISH THOMSON-HOUSTON CO., Ltd., RUFF, H. R., and CLARKE. M. G. Dec. 1, 1941, No. 15447. [Class 95] A device for use in the coating of electrodes, by dipping, comprises a container 7, for the coating material, mounted upon a turn-table 8, rotated at about 400 r.p.m., and a pipette 1, cranked at 2, and having an elongated mouth 3. The coating material, e.g. a suspension of barium or strontium carbonate in amyl acetate or in an amyl acetate-nitrocellulose mixture, rises in the tube 1, overflows at 3, and returns to the container through holes 5. A constant liquid level is thus maintained in the mouth 3, and the electrodes can be readily dipped therein. The continuous rotation of the container maintains the coating substance in suspension in the liquid, thereby maintaining constant proportions in the coating material. Specification 533,451, [Group XL], is referred to.

Title: Process of refining mineral oils
IPC: C10G73/06
Filed: 1936-06-05
Abstract: In treating hydrocarbon mixtures with selective solvents to obtain fractions of differing types or gravities or to separate out wax, the solvent consists wholly or principally of one or more methyl amines and the process is carried out in a closed system, maybe under pressure and/or at lowered temperatures.  As auxiliary liquids there may be used liquids which are wholly miscible with methylamine or selectively dissolve components of petroleum; examples are ammonia, methanol, ethanol, isopropanol, or other alcohol, water, monoethyl-ether of glycol, ethyl acetate, aniline, and aromatic hydrocarbons, e.g. benzol.  The substances treated include gasolene, kerosene, lubricating distillates, and petroleum.  The amines may be removed from the separated fractions by distillation or by washing, e.g. with water or methanol; in the treatment of gasolene a little may be left in to serve as an anti-detonant.  The treatment of lubricating oils reduces the proportion of clay required for decolorizing.

Title: Improvements in or relating to the production of silicon
Inventor: BUSH ERIC LANGLEY
IPC: C01B33/02
Filed: 1958-05-16
Abstract: Silane containing diborane is converted into pure silicon having a P-type resistivity of 3000-6000 ohm cms. by storage in the presence of water vapour for at least 24 hrs., to hydrolyze most of the diborane, and passage through a charcoal trap at -80 DEG  C. to remove water vapour, followed by introduction into the water-free gas of a controlled amount of water vapour in excess of that necessary to hydrolyze the remainder of the diborane and thermal decomposition of the water-containing gas.  The amount of water vapour may be up to 10,000 times, preferably 500 times, the amount of diborane.  The preferred amount may correspond to 0,5 p.p.m. of silane, which proportion may be produced by bubbling through water and then passing through a cold trap at -80 DEG  C.  The proportion of water vapour may be varied by varying the temperature of the cold trap.  The desired amount of water vapour may alternatively be produced by the introduction of a controlled volume of silane saturated with water vapour.  Specifications 745,698, 831,216 and 832,570 are referred to.

Title: Improvements in apparatus for measuring speed
IPC: G01P11/00
Filed: 1927-06-16
Abstract: 297,146. Midwinter, E. C. June 16, 1927. Indicating and registering time of working of machines.-An apparatus for measuring the average speed of a motor vehicle, or the number of revolutions of a machine running intermittently or variably during a desired running period comprises a spindle C driven from the mileage indicator of the motor vehicle or from the revolution counter of the machine, a disc D secured to the spindle, a second disc E in frictional engagement with the disc D, a spindle F driving a clock or time indicator, a screw thread on the spindle F carrying loosely the disc E and a spring S to maintain the disc E in contact with the disc D. If the friction between the discs becomes excessive the disc E tends to screw back on its spindle to reduce the pressure, thus automatically controlling the torque applied to the time indicator. By reading the indicators coupled to the shafts C, F, the time of running taken for the distance run may be ascertained in the case of a motor vehicle, or in the case of a machine the number of revolutions made in any desired running period may be obtained.

Title: Improvements relating to indicating or control devices for steam generators
IPC: G01F23/292
Filed: 1944-08-23
Abstract: 597,639. Photo - electric control of liquid-level indicating or alarm apparatus. BRADLEY, W. E., DRIVER, F. A., and TINLEY, E. L. Aug. 23, 1944, No. 16050. [Classes 40 (iii) and 40 (v)] In apparatus comprising a beam of light passed through a vessel containing a liquid, the level of which rises and falls with the level of liquid in an associated vessel, and in which a light-sensitive element is so located that the refractive properties of the liquid are used to control the illumination of the light-sensitive element which is included in an electric circuit operating an alarm or control device, a metal tube 10 connected to a high-pressure steam generator has openings 16; 17 opposite each other at a position slightly below the normal liquid level, a ring or frame in each opening carrying a transparent or translucent window 18, and the axes of the casing 28 carrying the light source 30 and of the housing 33 for the light-sensitive cell 34 are inclined to the axis passing through the centres of the windows 18. The arrangement may be such that the beam is incident over the cell 34 when passing through liquid in the tube 10, but is deflected clear of the cell, due to the changed refractive index when the liquid level falls and the beam passes through air or steam above the liquid. Alternatively, the beam may be refracted to impinge on the photo-electric cell 34 when the liquid in the tube falls below the predetermined level. A circuit for the former arrangement is shown in Fig. 3. When the beam falls on the cell 34, its resistance is low compared with a resistance 41 so that the grid of a valve 38 is negative with respect to its filament. When the beam is deflected off the cell its resistance becomes high relative to resistance 41, the potentials of the grid and filament become substantially equal and current flows through the relay coil 39 actuating contacts 43 to operate a control or alarm circuit. A time lag device 44 may be included to prevent the operation of the control circuit in response to liquid-level variations of short duration, and if an alternating voltage supply is utilized for the valve 38, a resistance 40 in the plate circuit is short-circuited to increase the average current through the coil 38. A circuit arrangement for operation of the alarm or control circuit by the deflection of the beam on the cell 34 is described in connection with Fig. 4 (not shown). In a modification of Fig. 2, (Fig. 1, not shown), the axes of the openings in the tube are inclined to each other and to the axes of the casings in which the light source and the light sensitive cell are mounted.

Abstract: 557,907. Variable-pitch propellers. HOOVER, W. S. Dec. 12, 1941, No. 16073. [Class 114] In a variable pitch propeller mechanism in which differential gearing for adjusting the blades is actuated by a fluid pressure motor driven by a fluid pressure pump under the control of an engine driven governor, means independent of the pump are provided for supplying pressure fluid to the motor to drive it in either direction for feathering and unfeathering while the engine is at rest. The blades 11, 12, Fig. 1, are connected by bevel gears 14, 15 to a bevel gear 16 having a spur gear 20 meshing with planet gears 19 which are carried by the hub 10 and mesh with a gear 21 driven by gears 22, 23, 24 from a gear 25 driven by the fluid pressure motor 36, Fig. 2. This motor is normally driven by a pump 28, which may be driven by the propeller engine or by a separate electric motor 29, and the speed of the motor 36 is such that no relative movement of the gears occurs. The return flow from the motor is controlled by a valve 46 operated by governor weights 49 so that variation of the speed of the engine results in change of speed of the motor 36 and consequent change of the pitch to restore the speed. As manual control 50 for the valve 46 is provided. To enable the motor 36 to be driven in either direction when the propeller engine is at rest, a pump 39 driven by an electric motor is provided and a valve 40 directs the flow to one side or other of the motor 36 as desired.

Abstract: 515,528. Switching systems for resistance welding. BRITISH THOMSON-HOUSTON CO., Ltd. May 31, 1938, No. 16300. Convention date, June 2, 1937. [Class 38 (iv)] A welding circuit 2 is supplied through discharge devices 7, 8 so controlled that current flows for a determinable number of half cycles of the supply 1 in periods the beginning of each of which are a determinable even or odd number of half cycles apart, further the power delivered to the circuit 2 is variable and if required the circuit can be supplied for one cycle only. Valves 24, 26 supply pulsations to a transformer 32, the periodicity being determined by condenser 31 and reactors 25, 27, and the start at either an ever or odd number of half cycles apart by the reversing switch 43 and transformer 45 supplying alternating potentials to their negatively biassed grids. The output pulsations from transformer 32 are rectified and applied to a valve 72 which discharges a condenser 68 which is charged through a resistor 70. Adjustment of the resistor determines the duration of the output pulsations from the valve 72 and condenser 68. The pulsations are applied to a valve 88 so associated with a phase shifter 99 and transformer 100 that peaked pulsations occur in the secondaries of the transformer, a peak occurring each half cycle only whilst the condenser 68 is being discharged and being displaced from the beginning of the half cycle according to the setting of the phase shifter 99. The output from the secondaries of the transformer 100 control valves 106, which in turn control the discharge devices 7, 8. Movement of switch 53 to the right puts the valves 24, 26 under the control of glow discharge device 57 and its associated condenser 56. Whereupon opening of switch 60 causes valves 24, 26 to generate one pulsation only, it being necessary to close and reopen switch 60 to obtain another pulsation, this action is described in Specification 515,537. Rectifiers 14 and 113 provide requisite D.C. supplies.
