IPC: F15B13/04
Abstract: 1,053,199. Power-assisted steering mechanism. BENDIX CORPORATION. Sept. 17, 1965 [Sept. 21, 1964], No. 39712/65. Heading B7H. In a power steering control valve comprising a valve spool 20 slidable in a body 10 formed with fluid pressure supply grooves 26, 28, a return groove 30 and power cylinder ports 32, 34, hydraulic reaction chambers 82, 84 at each end of the spool communicate with the cylinder parts 32, 34 through a slide valve 24 which limits the pressure differential in the chambers 82, 84 and hence the steering effort required. The valve 24 is displaced against spring-loading when the pressure differential at opposite ends thereof reaches a predetermined value so that a groove 50 or 58 moves out of communication with the low-pressure cylinder port 32 or 34 and into communication with a passage 36 or 38 from the supply grooves 26, 28 thereby increasing pressure in the appropriate chamber 82, 84. Restrictions in the passageways to the chambers 82, 84 damp actuation of the spool 20. The valve body 10 is secured to a drag link 12, and the spool to a bolt 112 actuated from a ball stud 100 connected to a pitman arm.

Abstract: 1,143,649. Homopolar generators. COMMISSARIAT A L'ENERGIE ATOMIQUE. 1 Nov., 1966 [26 Nov., 1965], No. 48881/66. Heading H2A. In a homopolar generator which is used for the generation of high-energy D.C. pulses of short duration, the voltage of this pulse is increased by a transformer employing part of the stator core as its magnetic circuit. Working flux generated by field coils 6, 7, passes along the paths shown from rotor 3 to circumferentially laminated stator core 11, through radial flanges 27, 28, 29, 30. The rotor is faced with conducting material 5, e.g. copper, which is connected by liquid brushes 8, 9, e.g. using mercury, to a toroidal single-turn, strip-wound primary winding 16 round the stator core 11. This winding may be closed, when it is desired to produce a pulse, by an electromagnetic switch 23-26. The secondary winding 12 consists of several strip-wound turns connected to outlet terminals 14. The core 11 is polarized by a fine wire winding, not shown. In operation, the machine is run up to speed and the brushes 8, 9 are filled with mercury simultaneously with the closing of switch 23-26.

Abstract: 1,145,742. Totalizator system. BELL PUNCH CO. Ltd. 17 June, 1966 [17 June, 1965], No. 25619/65. Heading G4A. Each keyboard, in a totalizator system, has a plurality of groups of keys, each group corresponding to a different system of betting (e.g. straight betting, forecast betting and quinella betting) and the keys are so arranged that each group uses the same set of common transmission leads to the central station. The mode of betting is determined by switches at the central station and indicated by lamps on each keyboard. The local keyboard circuitry includes a two-winding check relay, one winding being energized locally and one via a circuit including the central station. If both windings are not energized simultaneously the balanced armature of the check relay rocks and prevents the issue of a ticket.

Abstract: 1,231,433. Automatic voltage control. HOFFMAN ELECTRONICS CORP. June 26, 1968 [July 3, 1967], No.30536/68. Heading G3X. A direct voltage at output terminals 28, 30 is derived from an A. C. supply source 10, 12 by way of a transformer 16, rectifying diodes 20, 22, a resistor 24 and a series regulating transistor 26, the RMS value of the output voltage being maintained constant by the corrective control of transistor 26 in dependence upon input voltage variations. As shown, a control potential for the transistor 26 is derived from a D. C. source by way of a resistor 34 and a further transistor 32, and this control potential is modified, to take account of input voltage variations, by a circuit including a Zener diode 38 which is biased by a voltage inverse to that produced by the diodes 20, 22, this inverse voltage being derived from further diodes 44, 46 and a voltage divider 42, 40. Because of this biasing arrangement the Zener diode 38 conducts at a particular point in the half cycle when the applied voltage is at its normal value thus rendering the transistor 26 non-conductive with consequential clipping of the rectified half cycle of output voltage; if the input voltage increases the voltage at which clipping occurs is reduced, so that the area of each half cycle of rectified output voltage is maintained constant, i.e. the RMS output voltage is maintained constant. The circuit may include a diode 36 to compensate for temperature variation and a capacitor 48 to maintain the voltage at the junction 39 between the resistor 40 and Zener diode 38 constant between half cycles.

Abstract: 1,233,151. Lap forming machines. R. G. JENKINS (Owens-Coming Fiberglas Corp). 20 May, 1969, No. 25727/69. Headings DIN and D1R. [Also in Divisions B8 and H2] Filaments are formed into a mat by delivering them onto a collecting surface 50 from a plurality of delivery stations 26, moving the surface 50 past the delivery stations so that the fibres are collected as a uniform layer, continuously monitoring the operation of each station 26 to detect faults, and upon the detection of a fault automatically obstructing the delivery from the faulty station and reducing the speed of the collecting surface sufficiently to maintain or quickly resume the uniformity of the collected layer.  As shown, filaments are deposited from a plurality of delivery stations 26 onto moving conveyor 50. The filaments 16 are withdrawn from spinnerets, bundled into a strand 20, passed over idler wheels and driven pull wheel 30I and are projected downwardly. The pull wheels 30 are reciprocated by rods 72 (see also Figure 10) to project the filaments across the width of the web. When a strand disturbance or break occurs, the change in mechanical load on the pull wheel 30 results in a phase change of the induction motor 42 driving the pull wheel. This phase change is detected and amplified (Figure 9) and applied to a relay and timer circuit (Figure 8) to (a) move deflector 146 and filament receptacle 112 adjacent the pull wheel 30 to receive the faulty station filaments, and (b) reduce the speed of conveyor 50. The pull wheel 30 is also braked to rest and a knife (Figure 6 and 7) severs the strands from the pull wheel. Filaments fed into the receptacle 112 -can be chopped up by device 160. The rate of reciprocation of the pull wheel 30 can be varied with the changes in conveyor speed by detecting the latter with a selsyns which are used to control the speed of the motor which reciprocates the wheels 30, (Figure 10). The mat formed can have phenol-formaldehyde resin powder applied to it and be passed through a curing oven.
