IPC: F04B23/06
Filed: 1962-12-17
Abstract: 1,027,463. Hydraulic or pneumatic reciprocating motors; valve gear. GARBE, LAHMEYER & CO. A.G. Dec. 17, 1962 [Dec. 16, 1961; Sept. 7, 1962], No. 47422/62. Headings F1A and F1M. An hydraulic or pneumatic motor comprises a double-acting piston 35 with its supply and exhaust controlled by an electromagneticallyactuated valve 58 energised by piston 35 bridging contacts 39 at the end of each stroke. The stroke is adjusted by axial movement of abutment 45, by rotating threaded shaft 28. In another embodiment, Fig. 2 (not shown), electrical contacts control the reversing movements of a constant stroke piston (6) which is slidable relative to an output shaft (5) and has a collar (6a) engageable with abutments (5a), (9b) on the shaft, abutment (9b) being axially movable to vary the stroke of the shaft. An hydraulic stroke absorber is incorporated in the shaft which may be coupled to drive a pump through a clutch. An overload valve and flow-control valves are incorporated in the pressure fluid supply line. A plurality of motors may be operated with their circuits in series, and controlled by common valve means. Pressure-relief valves, acting in opposite senses, are provided in the motor pistons so that, if one piston reaches the end of its stroke before the others, the excess actuating fluid will pass through the valve and into the next cylinder in the series, until all the pistons have reached their end positions.

Abstract: 1,210,352. Testing circuit breakers. A. REYROLLE & CO. Ltd. Nov. 17, 1967 [Oct. 21, 1966], No.47443/66. Heading G1U. In a "parallel-type" circuit for the synthetic testing of a circuit breaker T, a spark gap SG2 or other surge diverter is included in the low voltage part of the circuit to protect against any accidental surges from the high voltage side, and a second auxiliary circuit breaker A2 is included between the spark gap and the power-frequency current source S. The spark gap SG2 is arranged to withstand the combined arc voltages of the first auxiliary circuit breaker A1 and the test circuit breaker T but to break down at a voltage less than the peak of the current source S recovery voltage. In use, spark gap SG1 is broken down at a time t a , Fig. 2 (not shown), shortly before the time (t o ) of a zero in the low voltage circuit current and at a short time thereafter (t o ) the spark gap SG2 breaks down. At the time (t b ) of the next zero in the high voltage circuit current the test circuit breaker T is opened and the recovery voltage (P) is developed across it. Capacitors Cr 1  and Cr 2  control the rates of rise of the recovery voltages in the low voltage and high voltage circuits respectively. A resistor R is included to provide a holding current for the spark gap SG2, but where SG2 is a device which remains conductive even after current therethrough has ceased, R is omitted.

Title: Method for fabrication of manganese oxide solid electrolyte capacitor
IPC: H01G9/032
Filed: 1975-11-19
Abstract: 1495200 Electrolytic capacitors MATSUSHITA ELECTRIC INDUSTRIAL CO 19 Nov 1975 [19 Nov 1974] 47594/75 Heading H1M In the manufacture of a solid electrolytic capacitor, formation of a manganese dioxide layer by pyrolysis of manganese nitrate is effected in a heating chamber of a radiant furnace which is not completely closed, in that the chamber communicates with the atmosphere through at least one vent, heat for the pyrolytic decomposition being transferred to the anode body from the chamber wall predominantly by radiation, the vent dimensions being such that the decomposition proceeds under a positive pressure due to temporary retention of gaseous decomposition products in the chamber. The manganese dioxide layer resulting is stated to have a more uniform particle size, in the range 0À1 to 50 Ám., more uniform density and porosity, better adhesion to the underlying layer and a more uniform surface than known pyrolytically formed layers. Further, fewer repetitions of impregnating with manganese nitrate and pyrolysis are required. However for a more stress-resistant layer, some of the pyrolysis steps may be effected in known manner using a circulating hot air furnace, so long as at least the final step is according to the invention. The manganese nitrate concentration may be as high as 83% by weight. The positive pressure is suitably 5 to 100 mm. H 2 O gauge, and appropriate relative values of chamber volume, evolved gas volume, vent area, substrate mass and surface area are given, as well as distance of the substrate from the chamber wall. Where a plurality of substrates are being treated simultaneously a heat conducting baffle in the chamber may ensure uniform heating thereof.

Filed: 1974-11-08
Abstract: 1442871 Massager L J KOVACH 8 Nov 1974 48407/74 Heading A5R A massager for removing wrinkles in skin comprises a positive displacement pump which produces a pulsating liquid flow at a nozzle 81 directed axially along a shield 77 intended to be applied to the skin with elastomer ring 89 forming a liquid seal, the liquid then flowing back to a reservoir 20 via a drain hole 88 from the bottom of which reservoir the pump obtains its liquid. The liquid is pulsed at 2200-3300 times per minute at a velocity of 13 feet/sec-18 feet/sec, the velocity being adjusted by a finger piece 29 which moves a stem 27 relative to a bore 26 of a by-pass valve communicating with the reservoir. The nozzle communicates with the pump via an elbow 63 releasably attached to a handle portion 11 of the massager and also via a bore 22 in the handle wall in which the by-pass valve is situated. The pump has a reciprocable piston 56 operated by a rechargeable battery operated electric motor via a transmission which includes an eccentric cam follower slidably engaged in a tracked cross head on the piston. The piston on a down stroke draws liquid from the reservoir via passages 40 and a suction-opened oneway valve 52 normally closed by a spring 54 supported on valve stem 53 slidable in a spider 51. The piston on the up stroke causes the valve 52 to close and forces the liquid to the nozzle.

Title: Compressor Control Valve.
IPC: F16K17/04
Filed: 1966-10-31
Abstract: 1,159,600. Fluid pressure control valve &c. BENDIX-WESTINGHOUSE AUTOMOTIVE AIR BRAKE CO. 31 Oct., 1966 [5 Nov., 1965], No. 48742/66. Heading F2V. In a valve, for controlling the delivery discharge of a compressor, fluid under pressure supplied to an inlet 16 passes through a chamber 18, ducts 30 and then raises a check valve 32 before entering, through duct 14, a fluid pressure reservoir, (not shown). As pressure within the reservoir, and consequently chamber 18, builds up, it is transmitted via ducts 52 and 56 to an annular groove 54 disposed within a member 25 closing an exhaust aperture 22. This pressure acts, through a resilient annular O-ring 58, on a split expanding metal ring 60 which, as a result, expands outwardly and into abutment with the upstanding flanges 48 of a U-shaped container 46, the exhaust closure member 25 being disposed within this container. Upon the pressures within the reservoir and chamber 18 becoming substantially equal, the forces acting on the opposed faces of a pistonlike member 28 cancel out and those acting on member 25 then become sufficient to overcome the closing bias of a spring 41 and so raise member 25 from its seat 24. Thereafter these forces act on the whole surface area of member 25 and that of the projecting ring 60 to ensure a rapid opening. Once the pressure within chamber 18 drops, the same happens within groove 54 and so members 58 and 60 retract and hence do not inhibit the return of member 25 to its seating, this return commencing when the reservoir pressure falls below a certain predetermined value. The metal ring 60 may be replaced by an annular garter spring (72, Fig. 4, not shown) which is coated and filled with rubber.

Abstract: 1328217 Photoelectrophoretic particles XEROX CORP 14 Oct 1970 [16 Oct 1969] 48781/70 Heading H1K A photoelectrophoretic imaging suspension comprises electrically photosensitive particles in a liquid carrier, the particles each comprising a resin core having electrically photosensitive pigment particles attached thereto. In an embodiment, particles of copolystyrene-n-butyl methacrylate containing carbon pigment are suspended in mineral oil, metal-free phthalocyanine particles added and then methylene chloride. The suspension is vigorously agitated and then the methylene chloride removed by a stream of air. The methylene chloride acts as a solvent for the resin particles and thus the photosensitive particles stick to the resin particles. In another embodiment yellow resin particles having yellow photosensitive carboxamide particles thereon, cyan resin particles having cyan photosensitive phthalocyanine particles thereon and magenta resin particles having magenta photosensitive Wachtung Red B particles thereon are suspended in mineral oil and used for full-colour copying. The resin particles may be thermoplastic or thermosetting and suitable resins are exemplified together with solvents for the resin. The photosensitive particles may be attached to the resin particles by (a) heating a suspension of the particles to soften the resin, (b) agitating the resin particles in the presence of very fine photosensitive particles, (c) adding the photosensitive particles towards the end of an emulsion polymerization process for forming the resin particles or (d) mixing the particles dry and then suspending them in a stream of hot air or solvent-laden air.

Abstract: 1356521 Reciprocating pump DONETSKY GOSUDARSTVENNY PROEKTNOKONSTRUKTORSKY I EXPERIMENTALNY INSTITUT KOMPLEXNOI MEKHANIZATSII SHAKHT 26 Oct 1972 49438/72 Heading F1A An apparatus for producing jets of liquid, e. g. for breaking rocks, comprises a pump cylinder 11 with a plunger 3 connected to an actuating piston 2 in a cylinder 1, compressed air in chamber 4 of cylinder 1 effecting the discharge stroke and hydraulic pressure supplied to chamber 5 effecting the return stroke, piston 2 being held at the end of its return stroke by a detent mechanism 37 in chamber 4 engaging in a piston recess 47, so that the hydraulic fluid in chamber 5 is drained before the piston commences its discharge stroke. In operation, from the position shown, pressurized liquid is supplied by pipe 8 to chamber 5 via throttle valve 9 to retract piston 2, and to pump chamber 16, a free piston 12 being provided in front of plunger 3. At the end of the return stroke, during which air from chamber 4 is compressed into receiver 7, piston 2 depresses detent plunger 42 causing it to move detents 40 outwardly to engage piston recess 47. Plunger 42 also acts via piston 53 to move slide valve 56 to connect the delivery from low-pressure pump 69 to control piston 59a, which moves upwardly to move valve 62a after a pre-set time interval to discharge liquid from chambers 30b of actuating cylinders 30 of sleeve valve 29. Opening of valve 29 by airpressure in chambers 30a releases the liquid from chamber 5 via ports 28. At the same time valve 62a connects delivery from pump 69 to control piston 59b which moves upwardly to move valve 62b after a pre-set interval to discharge pressurized liquid from the operating cylinder 23 of valve 19. This permits the compressed air acting in cylinder 26 to move valve 19 into its discharge position shown. At the same time, valve 62b connects delivery from pump 69 to control piston 59c to move valve 62c after a pre-set interval to connect delivery from pump 64 to cylinder 73 to move piston 53 to release the detent mechanism. Piston 2 then performs its discharge stroke. Piston 53 also moves valve 56 to connect pressure to pistons 59a, b and c to return them, and hence valves 62a, b and c, to their lowermost positions. The cycle is then repeated, with valve 62a connecting hydraulic pressure to cylinder 23 to move valve 19, and valve 62b connecting hydraulic pressure to chambers 30b to close valve 29. The time intervals of pistons 59a to c are set by adjusting rods 60a to c. Valves 75 and 76 control the rate of operation of the apparatus and are also used for testing purposes.
