Title: Coupling device for pipes or conduits
IPC: F16L29/04
Filed: 1936-05-12
Abstract: 476,801. Pipe couplings. AVERY, W. L., and AVERY EQUIPMENT, Ltd. May 12, 1936, No. 13410. [Class 99 (i)] [Also in Group XXIX] A coupling, more particularly for pipes conveying pressure fluid to brakes, comprises coupling parts 1, 8, each locating a spring-pressed valve 4, 12 which seat upon one another when the parts are brought together so as to preclude the trapping of air therebetween, and a union nut 32, which is located against abutments 55 on the part 1 for screwthreaded engagement with the part 8. The part 8 includes a spring- pressed piston 10 which is provided with a spigot portion 13 for engagement with a recess 14 in the socket 1, the piston 10 carrying packing-rings 16, 18, 20 as shown and being formed with a seating 11 for the valve 12, movement of the valve 12 in one direction being prevented by an abutment 22 in the coupling part 8. The arrangement is such that, upon insertion of the spigot 13 into the recess 14, the valves 4, 12 will abut, and the packing- ring 16 will be compressed between the part 1 and the piston 10 to prevent loss of fluid in the coupling when the valves are opened, opening of the valves being effected by relative axial movement of the part 1 and piston 10 with respect to the part 8 upon engagement of the latter by the nut 32. The Provisional Specification describes also a similar coupling having slightly modified coupling parts.

Abstract: 815,577. Hydraulic pit props. DOWTY MINING EQUIPMENT Ltd. April 23, 1957 [May 1, 1956], No. 13417/56. Class 20(2) An hydraulic telescopic pit prop comprises a plunger 19 adapted to be oscillated angularly about its axis to operate the pump 12 for extending the prop or moved along its axis to operate the release valve. The pump 12 is operated by a crank pin 26 on a plate 21 on the plunger 19 and the plate 21 is also adapted, by means of a bell-crank to operate the rod 17, Fig. 5, to open the release 46 by means of a spring plunger 48, a smaller valve 45 being initially opened by the rod 17 to give an initial reduction of pressure. A breather valve 36 is also opened by the plate 21. Both movements of the plunger 19 are produced by a handle 31 hooked on to a pin 29 on the plunger by means of a hook 52 or 53.

IPC: F01M5/02
Abstract: 134,605. Hooper, W. F., and Campling, G. Nov. 4, 1918. Force-feed lubricators; heating lubricant.-Large engines are prepared for starting by forcing heated lubricant into the bearings, cylinders, and valve casings. In the form shown, a small auxiliary internal-combustion engine D drives a rotary lubricating pump F through friction clutch E. The lubricant is conveyed by a pipe F<2>, passing through a chamber K heated by the exhaust from the engine D, to pipes N, N<2> leading to the cylinders and bearings of the main engine. The cylinder jackets of the two engines are interconnected by circulating-pipes 0, P, so that water or oil from the jackets of the auxiliary engine warm those of the main engine. In a modification, the lubricating oil passes through the jackets of the auxiliary engine, and may also pass through the heater K to the main engine.

Title: The manufacture of new compounds of the pyrazolanthrone series and of vat dyestuffs derived therefrom
IPC: C09B5/04
Filed: 1929-05-01
Abstract: 332,316. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). May 1, 1929. Pyrazolanthrone derivatives.-A 1-halogenanthraquinone-2-carboxylic acid is treated with hydrazine, preferably in the presence of a diluent such as pyridine, and the pyrazolanthrone-2-carboxylic acid thus obtained is converted to the acid chloride and condensed with an aromatic hydrocarbon or halogen derivative thereof to yield 2-aroylpyrazolanthrones. Alkylation or aralkylation on the nitrogen atoms of the pyrazole ring may be effected before, or after the condensation with the aromatic hydrocarbon. Those 2-aroylpyrazolanthrones which contain a free imino group in the pyrazole ring and a halogen atom in the aryl residue, oto the keto group may be, converted into vat dyestuffs by treatment with an acid-binding condensation agent such as potassium acetate or sodium carbonate. Advantageously a diluent such as nitrobenzene, and/or a catalyst, such as copper powder, may be present. Further ring closure appears to take place with elimination of hydrogen chloride to give 2N- aroylenepyrazolanthrones. In examples, 1-chloranthraquinone-2-carboxylic acid is converted to pyrazolanthrone-2-carboxylic acid halide, and condensed with toluene, p-dichlorbenzene, m-dichlorbenzene, and 2 : 4-dichlortoluene in presence, of aluminium chloride; 2-toluyl-N-methylpyrazolanthrone is obtained by methylation with dimethylsulphate before or after the condensation of pyrazolanthrone-2-carboxylic acid halide with toluene; 2 : 5-dichlorbenzoylpyrazolanthrone is heated in nitrobenzene with potassium and copper acetates and a little copper powder to give 2 : N-(3<1>-chloraroylene)-pyrazolanthrone (dyeing yellowish-red shades), and by these means 2 : 4-dichloro-5- methylbenzoylpyrazolanthrone is condensed to 2 : N-(3<1>-methyl-4<1>-chloraroylene)-pyrazolanthrone.

Patent GB-741387-A (GB)
Title: Improvements in or relating to automatic frequency control circuit arrangements
IPC: H03L7/081
Filed: 1953-05-15
Abstract: 741,387. Automatic frequency and phase control systems. STANDARD TELEPHONES & CABLES, Ltd. May 15,1953 [July 25, 1952], No. 13662/53. Class 38 (4). The frequency of an oscillation generation Wg is automatically synchronized with a reference oscillation Wo, Fig. 5, by feeding both oscillations to a phase-comparing device Q2 which through a smoothing circuit S provides a control voltage both for the generator Wg and for a phase-adjuster Q1 for regulating the phase of one of the inputs to the phase-comparer Q2, Q1 consisting of a coupling tube whose plate circuit is detuned by a reactance tube. In the circuit diagram, Fig. 7, the controlled generator comprises a back-coupled tube R1 feeding its output through a phase-adjusting amplifier R3 to the grid of a phase-comparing tube R5, the anode of which is supplied from the reference source Wo. The control voltage developed across the condenser-shunted resistor S is fed to a reactance tube R2 for controlling the frequency of the source R1, and to a second reactance tube R4 for adjusting the phase of the output from the amplifier R3 to the phasecomparer R5. Other types of mixers, for instance ring modulators, may be used for the phase comparison. Fig. 9 shows a modified circuit for use in synchronizing a sawtooth voltage with repetitive pulses, as in television technique. The sync pulses Wo and the sawtooth waveform Wg are mixed on the grid of a phase-comparing tube R2, the pulses riding on the steep slope of the sawtooth and providing a pulse output when the combined voltage exceeds a threshold value. A control voltage is thus derived across the cathode impedance K and is applied to the grid of the sawtooth source R1 to control its frequency. The control voltage is also amplified in a D.C. amplifier R3 and is applied as a bias voltage to the grid of the phase-comparer R2, thereby producing the same effect as if the phase of the sawtooth Wg had been adjusted.

Title: Improved process for the preparation of translucent rod-shaped bodies from powdered material
IPC: H01K3/02
Filed: 1925-05-27
Abstract: 243,251. General Electric Co., Ltd., (Assignees of Patent Treuhand Ges. f³r Elektrische Gl³hlampen). Dec. 16, 1924, [Convention date]. Gems, artificial.- Translucent rodshaped bodies are produced from powdered material, by feeding the material, in particular oxides and fluorides, upwardly into an oxyhydrogen flame and fusing it therein. By this means a rod-shaped crystalline body is built up from below, being projected on to the end of a graphite rod which is gradually withdrawn upwardly from the flame. The upwardly movable graphite rod a has secured in its lower end a rod b of refractory ceramic material, against which the flame of a blowpipe is directed. The oxygencontaining gas enters the chamber h through the pipe g and passing through the tube i becomes loaded with the material to be fused, which is fed from the hopper k. The material is carried by the oxygen-containing gas up the tube m into the combustion zone n of the hot pointed flame, forming a globule o on the lower end of the rod b. By slowly drawing the molten mass upwards the growth of large crystals of rod shape is facilitated. The blowpipe, is preferably enclosed in a chamber p. The process may be utilized for the preparation of amtificial stones.
