Title: Improvements in or relating to electric starting devices for internal combustion engines
IPC: F02N99/00
Filed: 1937-04-15
Abstract: 488,388. Turning - gear. SPERRY GYROSCOPE CO., Inc. April 15, 1937, No. 10823. Convention date, April 15, 1936. [Class 7 (v)] An engine starter comprises a starter clutch member 2 brought into engagement with an engine clutch member 1 by an auxiliary electric motor 38 and then driven for cranking the engine from an electric starting motor 3 through reduction gearing. As shown, the motors 3, 38 are coaxial with the clutch member 2. The hollow armature shaft 5 of the motor 3 is connected by a shear pin 7 to an inner shaft 6 squared at 8 to drive a sleeve 9, which has pinion teeth 16 for driving planet gears 17 .. 19. Each of these has an eccentric hub 20 rotatable in bearings 21 in a plate 23 having gear teeth for engagement with a fixed internal gear 28 having a larger number of teeth ; the hub 20 also rotates on a long roller bearing 25 secured in a two-part rotatable frame 10. The frame 10, which is thus driven comparatively slowly, is connected to the clutch member 2 through a sleeve 31 enclosing the motor 38, and through a one-way clutch 35 and a member 33 splined at 34 within the part 32 of the sleeve 31. The clutch member 2 is connected by a shaft 37 to a head 43 having cam surfaces engaged by teeth 41 on a collar 54 on the armature shaft of the motor 38, the field coils of which are mounted in the sleeve 31. The rotation of the motor 38 thus effects the axial engagement of the clutch member 2. A switch 58 is arranged to switch on the motor 38 slightly before the starting motor 3. The planetary gearing is operative only from the driving end and does not transmit any back kick from the engine, the strain of which is taken by the eccentrics and the gear teeth 24. The Specification as open to inspection under Sect. 91 states also that the invention is applicable generally to driving mechanisms other than engine turning-gear. This subjectmatter does not appear in the Specification as accepted.

Abstract: 1,124,182. Frequency discriminators; transistor mono-stable circuits. E. H. MASON & SONS Ltd. 14 Nov., 1966 [11 March, 1966], No. 10885/66. Headings H3A and H3T. [Also in Division G1] A circuit for measuring pulse rates of the order of 20 per minute comprises a monostable circuit T1, T2 triggered by the input pulses (e.g. from the transducer shown) and feeding the heater H of a thermistor ThA, the resistance of which is measured in a Wheatstone bridge and displayed on a meter M. Thermistor ThB reduces the effect of ambient temperature on the bridge. The transducer may respond to the drip of a liquid, and the meter then displays the rate of drip. A modified circuit, Fig. 2 (not shown), uses a slightly different mono-stable circuit with the heater of the compensating thyristor forming the common emitter load of the two transistors and with the base of the second transistor decoupled by a capacitor (C3) to reduce sensitivity to interference. A neon tube (N) is arranged in series with the transducer to give a visual indication.

Abstract: 940,327. Unscrewing closures. GEORGE S. CLAYTON Ltd. June 25, 1962 [March 24, 1961], Not 10897/61. Heading B8T. A rotary head 10 has an opening 11 to receive a bottle top whereby the screw stopper or cap thereof is received by a chuck or gripper comprising resilient rollers 16 freely rotatable on pins 17 carried by devices 13 hinged to the head by pivot pins 14. The rollers are urged towards one another by springs 15, and on receiving the closure are urged outwardly and grip the closure tangentially whereby it is unscrewed. Upward movement of the bottle is limited by a plunger 18 with a shoulder which abuts a stop; when depressed by a tappet 25, the plunger ejects the unscrewed closure from between the rollers. Rotation of the bottle is prevented by a fork-shaped clamp. The head is carried by a sleeve 20 slidable axially of a tube 21 which is driven by a belt pulley 23, and a spring 24 urges the head downwardly. A number of such heads may be mounted on a rotary disc located above a series of bottle platforms associated with fork-shaped bottle clamps; the platforms or heads may be vertically reciprocated to bring the closures into engagement with the grippers.

Abstract: 597,388. Electrolysis of alkali metal chloride solutions. HIRSH, B. W., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Aug. 27,1941, No. 10912. [Class 41] In electrolysing an aqueous alkali metal chloride solution employing a cell having a flowing liquid metal cathode beneath a carbon anode formed with vents at intervals along the path of the electrolyte through which chlorine can escape, the solution iscaused to flow through the inter-electrode space at a high velocity such that large stationary bubbles of gas no longer collect on the undersurface of the anode. The critical velocity, which is of the order of 7.5 cms. per sec. is signalized by a drop in the operating voltage. Preferably the speed of the chloride solution is so adjusted in relation to the current density and the distance between successive gaps in the anode, that at no place in the inter-electrode space does the time average ratio of the volume of gas (measured at cell temperature) to the. volume of solution exceed 1 to 4 and preferably lies between 1 to 10 and 1 to 20. Suitable cells for carrying out the process are constructed so that the anode fills substantially the whole of the cell above the inter-electrode space. Specifications 597,389 and 597,440 are referred to.

Title: Monomer soluble x-ray opaque polymethacrylate particles
IPC: A61K6/083
Filed: 1971-04-23
Abstract: 1330407 X-ray opaque polymethacrylate particles COE LABORATORIES Inc 23 April 1971 [1 May 1970] 11043/71 Heading C3P An X-ray opaque granular polymethacrylate composition comprises finely divided, solid, clear and colourless beads obtained from a suspension polymerization of an alkyl methacrylate, the beads being soluble in liquid methacrylate monomer to form a dough, and at least one organic halide compound comprising at least 50% by weight of bromine or iodine within the beads to impart detectable X-ray opacity thereto, the amount of the organic halide(s) being from 10-40% by weight of the beads. The composition is prepared by dissolving the organic halide(s) in monomeric alkyl methacrylate and polymerizing the monomer in suspension in a non-solvent vehicle in the presence of a macromolecular lyophilic suspending agent present in an amount up to 1% by weight of the vehicle and in the presence of a polymerization catalyst, e.g. benzoyl peroxide. The methacrylate monomer is preferably methyl methacrylate and may be used in conjunction with a comonomer, e.g. styrene, vinyl acetate, vinyl chloride, vinylidene chloride or ethylene glycol dimethacrylate. The suspension vehicle may be, for example, water, and the suspending agent may be a mixture of starch and carboxymethyl cellulose. Useful organic halides include tetrabromoethane, dibromopropanol, tetrabromobisphenol A, bromoform, p-dibromobenzene, dibromoethane, ethyl iodide, p-iodotoluene, 2,4,6-triiodophenol, iodobenzene, 1,3- diiodopropane, dibromoneopentyl glycol, dibromotoluene, bromopyridine, iodopropane and bromo vanillin. There may also be incorporated in the methacrylate monomer used ultra-violet absorbers, dyestuffs and brominated polyisobutylene (to improve impact strength &c.). The polymer beads obtained by the above procedure may be milled with non-toxic, naturally coloured, X-ray opaque pigments to enhance the X-ray opacity and to impart colour characteristic to the beads. Articles formed from the polymer beads can be detected by X-rays when present within the living body. The polymer beads can be admixed with methyl methacrylate monomer to form a dough which is then polymerized with an accelerator and shaped to form a dental prosthetic article; a blend of heavy metal pigment compounds may optionally be included in the admixture.

Title: Improvements in arrangements for obtaining substantially uniform electric currents from pulsating currents
IPC: H02M1/14
Filed: 1920-04-21
Abstract: 142,116. Siemens - Schuckertwerke. Nov. 15, 1915, [Convention date]. Converting alternating and direct currents.-In a work circuit carrying a pulsating direct current and containing one or more devices which generate voltages varying independently of the supply circuit, the alternating component of the pulsating current is caused by a transformer to pass through a circuit connected in parallel with the work circuit, this shunt circuit containing the secondary winding of the transformer in series with a voltage generator, the E.M.F. of which varies independently in the same manner as that of the devices in the work circuit. In the arrangement shown in Fig. 1, the work circuit contains a direct-current shunt motor 6 and is fed with pulsating current through a vapour rectifier 1. The branch circuit includes the secondary winding 9 of a transformer 12 and an E.M.F. produced by a generator 13 driven by an auxiliary motor 14 in parallel with the motor 6. The variations in size and direction of this E.M.F. corre. spond with the variations in the counter-E.M.F. of the motor 6. The E.M.F. of the generator 13 approximately balances the direct-current voltage across the branching points 10, 11, so that the direct current component of the pulsating current passes through the motor 6, while the alternating- current component is diverted through the branch circuit. In a modified arrangement, Fig. 2, the E.M.F. in the branch circuit is represented by the counter-E.M.F. of a shunt motor 13, whose exciting winding 17 is fed from the work circuit. The transformer in this arrangement is provided with a direct-current auxiliary winding 20 fed from a direct-current machine 21 on the shaft of the motor 13; this winding serves to neutralize wholly or partially the direct-current field of the transformer. Choking-coils 19, 24. are included in the circuits of the machines 13, 21 and the machine 21 is provided with a compensating winding 23 in the work circuit.
