Title: Power supply circuit
IPC: H04N5/63
Filed: 1974-07-23
Abstract: 1468451 Automatic voltage regulation SONY CORP 23 July 1974 [24 July 1973] 32555/74 Heading G3X [Also in Division H4]  A power supply circuit includes first and second loads connected in series across a D.C. source. Variations in the voltage across the first load are sensed and used to produce an additional voltage which is supplied to the second load to compensate for variations in its voltage consequent on the variations at the first load. As shown, a rectified mains supply 11, 12 is connected across horizontal and vertical deflection circuits 15, 16 in a television receiver. Variations in beam current cause effective changes in the impedance of circuit 15 which would be reflected in voltage variations in the supply to the vertical deflection circuit 16. To compensate for these variations, a voltage is tapped from a flyback transformer 13 and fed through a diode 49 to supplement the voltage applied to the circuit 16. In a similar manner, changes in the impedance of circuit 16 produce changes in the voltage tapped from the transformer 13 which tend to maintain the voltage supplied to the circuits 15, 16 at the required level.

Title: Hydraulic brake systems
IPC: B60T13/14
Filed: 1963-08-16
Abstract: 973,792. Fluid pressure control of brakes. J.G. KNOWLES. Aug. 16, 1963, No. 32557/63. Heading F2F. A vehicle brake control system comprises a pump P driven by a transmission shaft, a reservoir 33 for fluid under pressure and a control valve BV movable by the driver into three positions to respectively apply, hold or, as shown, release the brakes. In the latter position fluid from the wheel cylinders 12 is returned through ports 38, 29 and pipe 24 to the cylinder of the floating piston pump P which is driven by the eccentric 19 to charge the reservoir 33 through line 25 and ports 36, 31 until the fluid return to the pump ceases. When the valve rod 46 is moved to the brake application position (Fig. 3, not shown), the reservoir is connected through ports 31, 28 to the pump cylinder, the latter then supplying fluid at a higher pressure to the brake cylinders through ports 36, 38. In an intermediate position of the valve port 38 is isolated to hold on the brakes and ports 31, 36 are connected as in the first position of the valve, to allow the pump to recharge the reservoir if required. The reservoir pressure is sufficient to apply the brakes when the pump eccentric shaft 20 is not rotating.

Title: Improvements in wire drawing machine
IPC: B21C1/12
Filed: 1923-12-31
Abstract: 225,404. Dehn, F. B., (0. & J. Machine Co.). Dec. 31, 1923. Drawing wire. - A drum for a wire-drawing machine is accelerated gradually to reduce the starting strain by braking a handwheel carried by a member of an epicyclic gear train through which the drum is driven, the epicyclic gear being converted into a solid drive when the drum has reached normal speed. The drive shaft 12, Fig. 2, is rigidly connected to a gear 15 engaging with a pinion 20 keyed on a shaft 27 mounted in an arm 16 which is secured to the drawing-drum 10 but is loosely mounted on the gear 15. A pinion 21 keyed on the upper end of the pinion shaft is geared to a pinion 32 rigidly secured to a handwheel 45. The drum is provided with ratchet teeth 40 which may be engaged by a spring- pressed pawl carried by the handwheel and under the control of a handle 46. The wire having been passed through the hole 36 for attachment, the shaft 12 is started and initially drives the handwheel without rotating the drum. On braking the handwheel by hand-pressure, the drum commences to rotate and when speeded up to the speed of the gear 15, the pawl is engaged, thus rendering the drive solid. In a modification, particularly adapted for stringing the dies, the intermediate gear 22, Fig. 4, is formed with ratchet teeth which may be engaged by a pawl 26 fitting over the pinion shaft and having a tail engaged by a vertically slidable handwheel 35. The dies are strung by lowering the handwheel and rotating it by hand before starting the power shaft 12. The dies having been strung, the drum is run up to speed by the handwheel, the shaft 12 is then started and the handwheel raised or entirely removed, thereby allowing the pawl 26 to make a solid drive.

Title: Starter arrangement for split phase motors
IPC: H02K17/30
Filed: 1946-11-05
Abstract: 618,572. Induction machines. YUHAS, M. Nov. 5, 1946, No. 32868. [Class 35] [Also in Group XXXVII] A switch for connecting and disconnecting the starting winding of a split-phase motor during the starting period is operated by means of magnetic rods extending from the winding slots and carrying part of the stator flux to operate an armature carrying switch contacts. As shown for a 4-pole motor, a pair of stator slots which only contain main windings (i.e. no starting windings) carry a pair of soft iron bars 27, 28, which project axially from the slots and conduct some of the stator flux to operate a contact carrying armature 47. Both soft iron bars are covered by a fibre sleeve 33 and are wedged in the slots by insulating wedges 30 as shown in Fig. 4. Chattering is prevented by a copper slug 37 surrounding the bar 27 and fixed beneath its magnetic head 36. When the main winding is first energized at starting, the stator flux is high enough to overcome the spring 44 carrying the armature and close the contacts 49, 51, so completing. the starting winding circuit. As the motor speeds up, the stator flux falls and thus releases the armature which is restrained in the open circuit position by a guide yoke 54.

Title: Safety securing means for skis
IPC: A63C9/08
Filed: 1961-09-13
Abstract: 921,403. Ski bindings. R. RAMILLON. Sept. 13, 1961 [April 10, 1961], No. 32916/61. Class 132 (1). A safety securing device for skies of the type wherein an abutment pivots on a stationary pivot perpendicular to the surface of the ski 3 and a resilient force holds it normally in a position longitudinally of the ski while allowing it to pivot when a lateral stress exerted by the skier's boot exceeds a predetermined value, is characterized by two vertical spindles 19 at its rear end, on each of which pivots a jaw 21, defining together an arcuate surface against which the front of the skier's boot bears while means controlled by an eccentric member, a stud 7 rigid with the pivot are provided for securing the two jaws when the abutment is in its normal position of use and for releasing the jaws, whenever the abutment is pivoted in either direction. The safety securing means comprises a plate 2 screwed to the upper surface of the ski and having the pivot 5 on which a platform 12 and the body 13 of the abutment rotate. A sleeve 6 on the plate houses a ball 8, spring-urged to engage a notch in the platform. The body 13 houses a plate 17 with a slot 16 in which the stud 7 extending from the pivot 5 engages, the plate being spring-urged rearwardly by a spring 18. The wedge-shaped end 17 of the plate engages two studs 23 in the two jaws. The jaws have interengaging teeth so that when pressure is applied by the toe of the ski boot to the jaws, the jaws pivot and rotate the body 13, the stud moves in the slot and frees the plate from the studs, the jaws then being free to pivot in opposite directions.

Title: Improvements in or relating to optico-mechanical scanning devices
IPC: H04N3/08
Filed: 1958-10-15
Abstract: 890,379. Television. LABORATOIRES D'ELECTRONIQUE ET DE PHYSIQUE APPLIQUEES. Oct. 15, 1958 [Oct. 18, 1957], No. 32919/58. Class 40(3). A device for scanning a field in two directions comprises a plurality of plane mirrors 2 which are mounted parallel to each other and are each pivotable about an axis, the angle of rotation of the mirrors having, as a function of time, a sawtooth nature for scanning the field in one direction, and a rotatable element 4 provided with reflective, preferably concave, surfaces M for effecting a scan in the other direction, the pivot axes of said mirrors being located in a plane which is at an angle of about 45 degrees to the axis of a parabolic mirror C, which projects radiation from mirrors 2 through an opening between the mirrors on to the reflective surfaces M from which it is reflected back to a radiation sensitive element 5 arranged on the axis of the parabolic mirror. Element 5 is also preferably located on or near the axis of rotation of element 4. To prevent the formation of multiple images by reflective surfaces M a field limiting diaphragm is provided in focal plane of mirror 3. The diaphragm may take the form of two half plates located on either side of the plane of symmetry of the system, Fig. 2 (not shown), or two similarly positioned plates having a transverse dimension equal to that of the image portion scanned by surfaces M, Fig. 2a (not shown). A further construction of diaphragm is described for use with a system for scanning an infra-red field. Here the diaphragm elements are flat reflective surfaces which are approximately at right angles to the plane of symmetry of the system and approximately at right angles to the plane in which are located the pivot axes of the mirrors 2. Rotation of mirrors 2 is effected by the arrangement shown in Fig. 3 where the mirrors are pivoted at O and coupled at opposite ends to connecting rods B and B<SP>1</SP> respectively by rods T and T<SP>1</SP>. The connecting rods are supported by cranks M and P and carry rollers D and D<SP>1</SP> which engage cams C and C<SP>1</SP> on a common rotating shaft.' A spring system (not shown) urges the rollers against their respective cams. The cam profiles are shaped to produce the desired sawtooth rotation of the mirrors. The cam shaft is coupled by suitable gearing to the shaft for rotatable element 4 and driven by a common motor. Signals produced by radiation sensitive element 5 may be displayed on a cathode-ray tube, Fig. 5 (not shown), subjected to horizontal and vertical scans synchronized respectively with the scanning movement of mirrors 2 and rotatable element 4. Details and typical dimensions are given of a device for scanning an infra-red field.

Title: Method of controlling an industrial manufacturing process
Inventor: BOYD DAVID MILTON
IPC: F02B3/06
Filed: 1961-09-14
Abstract: <PICT:0973651/C4-C5/1> A method of controlling an industrial process performed in at least three separate consecutive processing zones, for example reforming gasoline, cracking heavy hydrocarbon oils to motor fuel, and production of ethylene from heavier hydrocarbons and of diesel or jet fuels by the catalytic hydrocracking of heavier oils, is characterized by producing a reference signal corresponding to the desired magnitude of a property of the product stream, producing a first control signal responsive both to said reference signal and to the actual magnitude of said product stream property, producing an intermediate control signal or signals each responsive to the immediately preceding signal and to the magnitude of a property or properties of an output stream or streams from an intermediate zone or zones, producing a final control signal responsive both to the immediately preceding control signal and to the magnitude of a first zone fluid output property, and adjusting a significant processing condition of a fluid input stream to said first zone in response to said final control signal.  Fig. 2 illustrates the application of the method to the reforming of gasoline. Gasoline charge stock passes through line 30 and heater 31, is mixed with hydrogen through line 40 and enters reactor 37.  The reaction temperature is sensed through means 34, for example a thermocouple, and is controlled by a controller 35 and line 36 by regulation using valve 33 of the fuel entering heater 31.  In reactor 37 there is a net temperature drop sensed in controller 47 via sensing means 45 and 46.  The effluent passes to receiver 39 wherein it is cooled and separated into a gaseous phase, which is substantially hydrogen and is recycled, and a liquid phase which passes through line 41 into fractionator 42 wherein the normally gaseous hydrocarbons are separated from the desired gasoline fraction, the gas discharging through line 43 and the liquid through line 44.  The ratio of hydrogen produced to normally gaseous hydrocarbons is sensed by controller 53 through flow rate measuring devices 49 and 51.  Controller 56 samples the final product through line 55 and known analytical means (not shown). The controllers are interconnected so that any variation from a desired process or product condition is relayed to controller 35 with consequential alteration of temperature in heater 31. The control means may be hydraulic, pneumatic, electronic or mechanical in nature.  Other stream properties may be measured, e.g. pressure, flow velocity, differential pressure, or colour.
