Title: Improvements in engine starter drives
IPC: F02N15/06
Filed: 1961-11-20
Abstract: 994,887. Starter drives. FABRICA ESPANOLA MAGNETOS S.A. Nov. 20, 1961 [May 12, 1961; Sept. 29, 1961], No. 41440/61. Heading F1K. A starting motor drive for an internalcombustion engine comprises a first driven member to be driven by the electric motor and drivably connected to the first driven member through a reduction gear and a free wheel clutch a second driven member providing a pinion to mesh with the ring gear of the engine, the free wheel of the clutch acting to transmit drive to the second driven member from the first driven member but not from the second driven member to the first driven member so that no drive from the ring gear can be imparted to the electric motor. In Fig. 1 the reference 1 designates an electromagnet which while it is causing the pinion 2 to advance by means of a fork 3, also operates a member which connects the battery to the starter motor. Flow of current to the motor is prevented until the pinion 2 is in mesh with the gear of the engine. An epicyclic gear shaft 10 carries three planetary gears 17. A stationary gear ring 12 for the epicyclic gear meshes with the planetary gears 17 and on an armature 13 of the motor is provided a sun pinion of the epicyclic gear. In Fig. 2 when current is supplied to the electromagnet a magnetic field is created which impels the core 22 forward consequently pushing the rod 24 which acts in turn on the pinion shaft 29 and shifts the pinion into engagement with the engine gear. The disc 25 connects the battery terminal 26 to the contacts 27 connected to the brush yokes 28. The drive includes an epicyclic gear and the free wheel clutch 18.

Abstract: 1497106 Feeding and delivering sheets XEROX CORP 9 Oct 1975 [22 Nov 1974] 41443/75 Heading B8R Sheets are separated in turn from the top of a pile 102, Fig. 2 and 4, by suction cups 133b which first raise each sheet and then feed it forwards to rollers 110, 110a, whence it is fed to rollers 203a, 203b and to a belt 202. The action of the separators and the drive of the rollers and belt are controlled by photoelectric detectors 174, 175 in such a way that a predetermined number of sheets are fed on to the belt with a predetermined spacing, the belt then being stopped and the feed stopped while the sheets are photographed. The spacing is controlled by adjusting the position of the detector 175. The sheets are then delivered over an inverting roller 404 upside down on to a slower belt 402 to form an overlapping stream and to be stacked against a fixed plate 402a. After the set of sheets has been forwarded to the belt 202, a solenoid causes the top of the pile to be sensed, and if it is too low a motor rotates threaded rods 104 to raise the pile support 103. After each sheet is separated, a further photoelectric detector senses a darkened part of a wheel 122 and stops the separator. Before each sheet is separated, a solenoid 180 causes a spring member 162 to straighten the pile by pushing it against a back plate 184, while air is blown into the upper part of the pile by nozzles 186, 187.

Abstract: 1,141,569. Coated wire. SIEMENS A.G. 12 Sept., 1967 [13 Sept., 1966], No. 41548/67. Addition to 1063899. Heading B2K. A process for coating an electrically conductive member with a thermoplastic synthetic resin comprises (a) drawing the member through a thixotropic dispersion of the thermoplastic synthetic resin in a liquid containing a forming agent, the viscosity of the dispersion in the region where the member emerges from the dispersion being reduced mechanically, to deposit on the member a covering of the thermoplastic synthetic resin, (b) heating the covered member to drive off said liquid and to sinter and fuse the thermoplastic synthetic resin into a homogeneous foamed coating, and (c) forming a coating of an unfoamed thermoplastic synthetic resin on said homogenous foamed coating. The coating of unfoamed thermoplastic synthetic resin may also be formed by drying the member through a dispersion of a thermoplastic synthetic resin in a liquid not containing a foaming agent in the same way as the formed coating is applied. The thickness of the final coating may be from 1/3 to 1/5 of the total wall thickness of the insulation. The coatings may be applied as a continuous operation. The electricallyconductive member may be a wire and the thermoplastic synthetic resin may be polyethylene.

Abstract: 909,193. Nuclear power plant. ROLLS-ROYCE Ltd. Oct. 19, 1960 [Dec. 7, 1959], No. 41583/59. Class 39 (4). The nuclear reactor 18 and steam generator 21 in compartment 11 produces superheated steam to drive turbine 25 in compartment 12 which is coupled to the propeller 34. The bulkhead separating 11, 12, to prevent excessive pressure rises in 11, 12 due to steam leaks, is constructed as a vertical steam condenser through which water may flow from tank 39. Diaphragms 44a, 44b are rupturable by a pressure applied at one side, but not by a pressure at the other side. Hence, with a rise in pressure at 11, due to a steam leak, 44a is ruptured, but not 44b, and steam flows upwards through the condenser. Uncondensed steam will burst disc 45b and pass into 12.

IPC: G11B3/70
Filed: 1964-10-13
Abstract: 1,118,381. Electric analogue calculating; gramophone records. ELECTRIC & MUSICAL INDUSTRIES Ltd. 1 Oct., 1965 [13 Oct., 1964], No. 41668/64. Headings G4G and G5R. [Also in Division H4] The waveform of the groove of a gramophone record is formed during the recording process to allow for the subsequent elastic deformation of the groove by the stylus of a pick-up during playback. Compensation for tracing distortion arising from the fact that the record is cut by a chisel and is played back with a stylus having a spherical end may also be provided. A circuit is provided which develops a voltage representative of the elastic deformation and corresponding to equation where S is Poisson's ratio and E is Young's modulus for the record material, R is the radius of curvature of the stylus point, u is the groove velocity relative to the stylus, W is the stylus pressure, c is the stylus compliance , b is the frictional damping factor of the stylus, m is the effective mass of the stylus, y is the distance in a direction normal to an unmodulated groove wall and y and y are the first and second derivatives with respect to time. The circuit (Fig. 3, not shown) includes differentiating networks, integrating networks, addition, subtraction and multiplication networks, a squaring circuit and function generators which raise various voltages to powers such as the two-thirds power and the one-third power. The factor Á<SP>-5/3</SP> is developed by a potentiometer wound to this power law or one wound to a convenient law working in conjunction with a diode function generator. The various function generators each comprise a plurality of networks (A, B, C) &c., (Fig. 4a, not shown), each of which consists of three resistors connected to a diode (Da, Db, Dc) &c., one diode for each network. A keep-alive current ensures that current flows through one diode. Each multiplier comprises two Zener diodes (37, 38), Fig. 5 (not shown) connected to opposite ends of the secondary winding of a transformer (36). The multiplier includes a transistor (31) to the base of which is applied a signal representing the multiplicand. The multiplier input is applied to a common connection of the Zener diodes (37, 38) and as this input varies the impedances of the Zener diodes (37, 38) vary in exponential manner. Alternatively the multipliers may employ Hall effect devices or diode function generators connected as a quarter squares multiplier. Compensation for geometric distortion is provided in a block (26) comprising eight delay elements and nine summing circuits. The outputs of these summing circuits are connected by respective diodes to the output of the block (26), the diodes being so arranged that the output is the most negative of the outputs of the summing circuits. The output, after differentiation in a block (27), is applied to a disc cutter.

Title: Battery testing method and apparatus
IPC: G01R17/10
Filed: 1972-09-13
Abstract: 1396359 Measuring the state of charge of a battery K S CHAMPLIN 13 Sept 1972 [14 Sept 1971] 42536/72 Heading G1U [Also in Division H2] The state of charge of a battery is determined by measuring a quantity inversely proportional to its open circuit A.C. impedance, this being effected either by making the battery one arm of a bridge and causing a small oscillatory current with zero mean to pass through it, or by applying a known oscillatory voltage across the battery and arranging that the open circuit battery impedance controls the gain of a feedback amplifier, suitable D.C. blocking capacitors being used in both arrangements. In the first arrangement Fig. 5, the battery under test, which is shown in dotted lines as comprising a perfect battery Vo in series with an open circuit A.C. impedance R' s , forms with resistors R 1 , R 2  and R 3  a bridge having an oscillatory supply (about 100 c/s) V 1  across the horizontal diagonal and an error voltage V 2  across the vertical diagonal, this voltage being scaled by resistors R 6 , R 7  to provide an output error voltage V 3 . The scaling resistor R 7  is coupled to the adjustable part R 5  of resistor R 2  in such a way that the sensitivity of the bridge is maintained constant. Capacitors C 1 , C 2 , C 3  as shown block any D.C. In use the bridge is connected to each lug of the battery by a connector Fig. 7, which is arranged to connect two leads 14, 16 independently to the lug, this being effected by insulating a member 62 of the connector by a fibre washer 54, and the resistor T 2  is adjusted to zeroise the error voltage V 3 . Resistor R 2  is then inversely proportional to the value of the open circuit A.C. impedance R' s . In a practical realisation of this arrangement Fig. 8 (not shown), the source of A.C. (80, 82, 88) is powered by the battery under test and an error voltage amplifier (112, 130) is arranged to drive a meter (32) in such a way that full scale deflection corresponds to zero error. In the second arrangement, Fig. 9, the battery under test is connected as shown and a known A.C. voltage V 1  is applied across it. It can then be shown that the output voltage V e , which can be displayed on a suitable meter, is inversely proportional to the open circuit A.C. impedance R' s  independently of the open loop gain of the amplifier. A practical implementation of this arrangement Fig. 11 (not shown) is also described.

Filed: 1961-11-28
Abstract: In a method of bonding a cermet to a metal cladding (Division B3) and more particularly of a cermet nuclear fuel pellet to a can (Division G6), there is described a method of successively electroplating a cermet, of uranium and plutonium dioxide in a stainless steel matrix, with nickel and copper.  The cermet body is prepared for electroplating by an anodic etching in an aqueous solution of 20% sulphuric acid for 1/2 -1 minute using a current density of at least 100 amp./sq.ft., and then washed in cold water. The cermet is then placed in a plating bath containing nickel as the sulphate at a concentration of 225 gm. per litre in aqueous 3% sulphuric acid. A current density of 150-200 amp./sq.ft. is applied for about 1 minute, using the cermet as the anode in conjunction with a nickel or lead cathode.  The current is then reversed and cathodic plating with nickel proceeds for about 5 minutes, using the same current density. After a further cold water rinse, the cermet is transferred to a second plating bath containing copper as the sulphate at a concentration of 250 gm. per litre in an aqueous 5% sulphuric acid with an addition of 1 gm. per litre of C6H5OH.  Plating proceeds for about 5 minutes using a copper anode and a current density of 50-200 amp./sq.ft. to form a copper deposit of approximately 0.001 inch.
