IPC: F02B71/06
Filed: 1955-06-16
Abstract: 772,703. Piston-operated gas generators. SOC. D'ETUDES ET DE PARTICIPATIONS, EAU, GAZ, ELECTRICITE, ENERGIE SOC. ANON. June 16, 1955 [June 16, 1955; Dec. 28, 1954], No. 17461/55. Class 7 (1). [Also in Groups XXVI and XXIX] In a piston-operated gas generator in which air from a compressor cylinder is supplied to an engine cylinder and power gas is delivered from the engine cylinder and comprising an auxiliary gas turbine adapted to drive one or more auxiliary devices of the gas generator, the auxiliary turbine is arranged to be driven by air derived from a scavenge air receiver located between the compressor and engine cylinders. The invention is applicable to locomotives, marine installations or electricity producing plants. As shown a turbine 13 is employed for driving one or more auxiliaries of a gas generator 1 through a reduction gear 33a, 33b. The turbine may drive a cooling water pump and/or a fan for cooling the cooling water or other auxiliaries. The turbine is driven by compressed air from the reservoir 10. The number of valves 17a, 17b open is regulated by means of a centrifugal governor 20 which operates a rack 23 by means of a pneumatic or hydraulic servomotor piston 29. The air may be heated or cooled before reaching the entry to the turbine. Heating may be effected by an exchanger 34 or by burning some fuel in the piping 19. When the air is cooled the turbine exhaust air can be used for cooling the drivers compartment of a locomotive. The gas generator could have two opposed pistons with synchronising means. The tension of the spring 36 of the governor can be made to vary in dependence on the pressure in the casing 10 or in the chamber 18. A stop may be provided inside the cylinder 41 to arrest movement of the piston 40 when the pressure in chamber 18 reaches a value corresponding to the maximum pressure of the range of pressures.

Abstract: 628,325. Corrugated sheet metal structures; reinforced concrete; girders; slabs. PERRY, A. R. June 11, 1946, No. 17462. [Classes 20(i), 20(ii), 20(iv) and 87(i)] [Also in Group XXIII] A composite structural unit is formed of corrugated metal sheets 1, 2, Fig. 1, in facing or laminated relationship with the corrugations angularly or parallely disposed and welded together at their crossings or adjacent parts 3, the unit being filled with or embedded in concrete &c. The unit may be of plate or slab form for use in floors, walls, roofs &c. or it may be formed as a girder, arch, stanchion or column. As shown in Figs. 3, 4 a composite floor slab is formed by a series of upper and lower sheets 4, 5 with their corrugations at right-angles and connected by spot welds 6. The upper sheets 4 are apertured at 7 and concrete 8 laid upon the sheets 4 penetrates the space between the upper and lower sheets. The sheets are contained within an angle iron frame 9 slotted at 11 to receive and secure the ends of strip metal members 9a, 10 disposed between the corrugations of the sheets. A layer of bitumastic composition 15 covers the concrete layer 8 and the underside of the slab is covered with ceiling board 16 secured to the strips 10 or to the lower sheets 5. The lower sheets 5 may also be perforated to allow the concrete to penetrate to the ceiling board 16. When the sheets are not contained within a frame the metal strips 9a, 10 or rods &c. may be welded to the corrugations and may extend beyond the edges of the sheets to act as bearers. Plain metal sheets, strips or rods may be welded at one or both faces of the unit or between pairs of the corrugated sheets. The ridges of the corrugations, which may be of flattened form, may be laid in longitudinal coincidence and the unit bent into the form of a cylinder for use as a column or stanchion. Some of the corrugations may be packed with sound or heat insulating material. According to the Provisional Specification, the sheets may be of different size to form projecting margins for interlocking or support purposes, while the edges of one sheet may be slit to form tongues which are folded over the edges of the other sheet. Beam or girder units are built up in laminated form by disposing sheet upon sheet bent to the required section with the corrugations running alternately longitudinally and transversely.

Title: Improvements in brake mechanism
IPC: F16D55/39
Filed: 1931-06-17
Abstract: 374,286. Vehicle wheels ; brakes. ECLIPSE MACHINE CO., Elmira, New York, U.S.A. June 17, 1931, No. 17578. Convention date, June 19, 1930. [Classes 103 (i), 144 (i), and 144 (ii).] A brake particularly for aeroplane or other vehicle wheels of the type in which the tyre rim 32 is mounted directly on the hub, comprises a sleeve 14 on the axle 11 and anchored to the frame member 10 and brake discs 25, 26 alternately splined to the sleeve 14 and to a sleeve 27 rotating with the hub. The discs are forced together by screw- and nutmechanism comprising a shaft 59 passing through the axle. This mechanism gives a quick initial movement and a subsequent high mechanical advantage for applying pressure to the discs. On the axle 11 secured to the frame member 10 is sleeved the tubular anchor member 14 provided with splines 16 and screwed into a plate 12 bolted to the member 10. The member 14 is anchored to the plate 12 by a collar 17 splined on the member and by a sleeve 20 splined on the collar and on the plate 12. The sleeve 20 is positioned by a spring ring 24. End hub members 42, 46 mounted in antifraction bearings 43, 47 support the tyre rim 32 provided with an integral flange 36 and a detachable flange 37 splined on the rim and positioned by a spring ring 40. The members 42, 46 are shouldered to support a sleeve 27 which is splined to the rim 32 and spaced therefrom as at 35 to provide heat insulation. A spacing ring 54 is disposed between the end member 46 and the rim and is held by nut 55. The bearing 47 is maintained in adjusted position by a member 50 and locknut 51 screwed on to the end of anchor member 14. The valve stem 74 extends through the rim 32. The sleeve 27 has internal splines for one set of brake discs 26, the other set 25 being splined on the member 14. Friction rings are disposed between the discs. A plate 29 for taking the end pressure of the discs abuts on stops 31 on the member 14. The means for applying braking pressure to the discs comprises a pressure plate 30 engaged by a nut member 70, both splined on the member 14. The nut member 70 has a quick pitch threaded engagement with a further member 64 which forms a nut having slow pitch threaded engagement with a shaft 59 extending through the axle 11 and carrying an operating arm 58. A torsion spring 66 connects the shaft 59 to the nut 64. Thus when the shaft 59 is turned, the nut 64 first turns therewith and the nut 70 and pressure plate 30 are given rapid axial movement to take up the clearance in the brake, the spring then yielding so that the nut 64 traverses the shaft to apply pressure to the discs at the higher mechanical advantage determined by the slow pitch thread 63.

Filed: 1976-04-30
Abstract: 1520192 Converters HITACHI Ltd 30 April 1976 [12 May 1975] 17779/76 Heading H2F  A gate control circuit for a chopper circuit 6 having a main thyristor and an auxiliary thyristor for turning off the main thyristor, comprises a square wave oscillator 1 and a magnetic phase shifter 2 for producing a variable pulse width square wave signal, an integrator 11, a circuit 12 for providing an output pulse signal the pulse width of which is determined by the instants at which the integrator output falls below a first level and rises above a second level, and means 5, 9, 13 for turning on the main thyristor in response to each output pulse from the circuit 12 and for turning on the auxiliary thyristor in response to the termination of each output pulse from the circuit 12. The width of the output pulses from the phase shifter 2 depends on the magnitude of a control signal supplied to the phase shifter. The pulses from the phase shifter charge a capacitor in the Miller integrator 11, the capacitor being discharged at the termination of each pulse. Each time the integrator output signal falls below the first level, the Schmitt circuit 12 produces an output pulse which is terminated when the integrator output signal rises above the second level. The output pulses from the circuit 12 are fed via an amplifier 9 to the main thyristor in the chopper 6. At each trailing edge of the output pulses from the circuit 12, a differentiator 13 produces a spike pulse which is fed via an amplifier 5 to the auxiliary thyristor in the chopper 6, thereby turning off the main thyristor. By varying the width of the phase shifter output pulses, the width of the output pulses from the circuit 12 is controlled to vary the conduction period of the main thyristor.

Filed: 1947-07-07
Abstract: 4-Aryl-4-aminomethylpiperidine derivatives of the general formula <FORM:0640168/IV (b)/1> wherein Ar represents an aromatic radical (carbocyclic or heterocyclic, preferably monocarboxylic, such as phenyl, naphthyl, thienyl, pyridyl or quinolyl, optionally carrying substituents, e.g. alkyl, aralkyl or aryl groups, halogen atoms such as chlorine, bromine or iodine, tertiary amino groups such as dimethylamino, piperidino or morpholino, or alkoxy or aryloxy groups), X represents one of the following carboxylic acyl radicals: carbamyl (-CONH2), N-substituted carbamyl (e.g. N-ethyl- or N : N-dimethyl-carbamyl), carbalkoxy (e.g. carbomethoxy, carbethoxy, carboisobutoxy or carbo-n-hexoxy), alkanoyl (e.g. acetyl, isobutyryl, valeryl or cyclopentanecarboyl) or aroyl (e.g. benzoyl, p-toluyl, a -naphthoyl or 2-thenoyl), and Y represents hydrogen, or X as defined above, or a monovalent hydrocarbon radical (e.g. methyl, ethyl, n-butyl, n-hexyl, cyclohexyl, benzyl, phenethyl, phenyl or naphthyl), are manufactured by treating the corresponding free amino compounds (X=H) with a carboxylic acylating agent on nitrourea.  Suitable acylating agents are acid chlorides (carbamyl and N - substituted carbamyl chlorides, alkyl chlorocarbonates, and alkanoyl and aroyl chlorides) or acid anhydrides.  When the 1-position in the starting materials is unsubstituted (i.e. Y=H), acylation will occur at this position as well as in the aminomethyl group, but products in which Y represents hydrogen are obtainable if the 1-position is originally occupied by a benzyl group which is removed, after the acylation, by hydrogenation in the presence of a palladium catalyst.  Examples describe the preparation of compounds containing certain of the groups specified for X and Y above.  The products, in the form of free bases or salts (e.g. with sulphuric, hydrochloric, hydrobromic, phosphoric, sulphamic, acetic, citric, benzoic or cinnamic acid) are useful as analgesic, antispasmodic or sedative agents.  4 - Aryl - 4 - aminomethylpiperidines, of the general formula above in which X represents hydrogen, are obtainable by catalytic hydrogenation of the corresponding 4-cyanopiperidines using Raney nickel in the presence of excess of ammonia.  The Specification as open to inspection under Sect. 91 comprises also the manufacture of compounds of the general formula above in which X or Y or both may represent a guanyl radical or a hydrocarbon-substituted guanyl radical (e.g. N-methylguanyl, N : N-diethylguanyl or N : N1-dimethylguanyl, also aralkyl-or cycloalkyl-substituted guanyl radicals), these groups being introduced by the action of guanylating agents such as cyanamide or an S-methylthiouronium salt, including N-mono-, -di- or -tri-hydrocarbon-substituted-S-methyl-thiouronium salts.  Examples of this process are included.  This subject-matter does not appear in the Specification as accepted.
