Title: Improvements in disc brakes
Inventor: HAMBLING STEWART KEVERN
IPC: F16D66/00
Filed: 1962-07-12
Abstract: 1,061,142. Disc brakes. GIRLING Ltd. July 11, 1963 [July 12, 1962; Aug. 23, 1962; April 20, 1963], Nos. 26792/62, 32382/62. and 15678/63. Addition to 934,172. Heading F2E. In a disc having one pad urged into engagement with the disc by actuation means carried or incorporated in a caliper. Fig. 2, or clamping member, the other pad being urged into engagement with the disc by the reaction on the caliper or clamping means which slides or swings relative to the disc, two outwardly extending lugs 53 are provided at opposite ends of the backing plate 48 of at least the directly actuated pad and engage torque taking guiding surfaces on plates 54 detachably secured to the caliper or clamping member or surfaces on the caliper or clamping member itself. The circumferential component of drag is taken by the radial surface of the plate 54 with which any given point of the disc first comes into alignment in either direction of rotation while the radial component of drag is taken by the surface 56 of the other plate 54. On removal of one of the plates 54 the backing plate 48 can be moved radially inwards to disengage it from the other torque plate 54 which may be fixed or also detachably screwed to the caliper so that the pad can be removed in a circumferential direction. If the lugs engage the caliper, direct pins passing through the lugs and detachably fixed in the caliper may prevent radial movement of the backing plate. Alternatively plates detachably secured to the caliper and projecting into recesses in the lugs on the backing plate may take the radial component of drag. In another embodiment the torque is taken by a plate detachably secured at one end to the caliper, the other end having a recess which co-operates with a peg fixed to the caliper. In a further embodiment the torque-taking guide plate is provided with resilient fingers which bear on the backing plate and the caliper to prevent rattle. Automatic adjusters may be provided for both the pads, one for the pad applied to the disc by the caliper reaction comprises a nut (95), Fig. 8 (not shown), having ratchet teeth (96) in screw-threaded engagement with a non-rotatable stem (91) of a pad backing member (90). A pawl (97) carried by a rod (98) moved at right-angles to the axis of the disc and moving with a hand-actuating lever causes the nut (95) to rotate when adjustment is required. In another embodiment of adjuster, Fig. 10 (not shown), the backing plate (49) is engaged by a stem (102), screw-threaded in a hole (103) in the caliper and carrying a ratchetwheel (105), the latter being rotated when adjustment is required by a spring-loaded pawl (106) which is rocked about pivot (108) by a stationary abutment (111) on movement of the caliper.

Filed: 1971-04-19
Abstract: 1292577 Automatic control of speed REGGIANI SpA 19 April 1971 [22 June 1970] 26877/71 Heading G3R [Also in Division B6] In a machine wherein material such as fabric is temporarily attached to a belt 1 as by glueing and is fed past at least one rotatable printing screen 6, the belt is driven by a motor-driven driving-pulley 2 and the screens 6 are rotated by a motor 18 through transmission gear 7, the speed of the motor 18 being regulated by transducer means producing output signals representative of the speed of the belt 1 so that the screens 6 rotate with a surface speed equal to that of the belt 1. As shown, a wheel 8 engaging and driven by the belt 1 is coupled by a shaft 27 to an electromechanical transducer 9 which produces a series of pulses with a frequency proportional to the belt speed. These pulses pass to an amplifier converter 10 controlling a step-by-step motor 11 which rotates through a constant angle for each pulse. The motor 11 through gears 12, 13 rotates a screw 14 causing axial displacement of a nut 15 which operates a hydraulic distributer 16 to connect a pump 17 to the hydraulic motor 18 which drives the screens 6. The motor 18 is coupled to the nut 15 by a transmission 19 so that during rotation of the motor, the nut tends to move towards its initial position until a stable position is reached wherein the motor 18 rotates at the required speed. The axis of the wheel 8 is adjustable in a horizontal plane, Figs. 2, 3 (not shown) so that the speed of the wheel can be regulated in relation to that of the belt 1 to compensate for errors due to slippage. An optical displacement sensor may be used instead of the wheel 8. When printing is interrupted by stopping the belt 1 and lifting the screens 6, the screens continue to be driven to prevent dripping of ink, etc., this being effected by a variable frequency squarewave generator 20 connected to the amplifier 10 and which automatically starts to operate when printing stops.

Title: Improvements in thermal power plants
IPC: G21C1/04
Filed: 1947-10-09
Abstract: 631,069. Fluid-pressure servomotor-control systems. AKT.-GES. FUR TECHNISCHE STUDIEN. Oct. 9, 1947, No. 27155. Convention date, Nov. 2, 1946. - [Class 135] [Also in Group XXVI] A gas-turbine plant in which a gaseous working medium describes a closed circuit including at least one compressor and at least one turbine and receives heat in a heater from an intermediate heat convector fluid circulating in an auxiliary circuit containing a nuclear reaction pile, has means for regulating the velocity of circulation of the heat convector fluid so that it is substantially proportional to the quantity of heat to be transmitted to the gaseous working medium. In the gas-turbine plant shown the gaseous working medium flows through a closed circuit including a compressor 1, a heat exchanger 2, a heater 3 in which heat is supplied to the working medium from an external source, a turbine 4 which drives the compressor 1 and a generator 5 and a cooler 71. The heat supplied to the heater 3 is obtained from a nuclear reaction pile 50 through which and the heat exchanger 3, a heat convector fluid is circulated by a blower 52. A decrease in load on the generator 5 causes the governor weights to fly out and turn the lever 9 counterclockwise thus lowering the valve 11. This allows servo fluid to pass into the space above the piston 13 which then moves downwards and through the collar 17 opens the valve 19. At the same time the lever 24 is moved in a counterclockwise direction which causes the collar 26 to open the valve 27 and the lever 49 to switch on the driving motor 45 of the charging compressor 44. Working medium is then extracted from the circuit at the point 38 and flows through pipe 37, valve 27 and pipe 41 into the suction 43 of the compressor 44 from which it is discharged through the pipe 46, valve 19 and pipe 34 into the storage vessel 35. The pressure at the point 59 then falls and the piston 56 is moved to the right by the spring 57. This causes the contact arm 59<SP>1</SP> to move over the variable resistance 60 and thus slow down the motor 61 of the blower 52 which circulates the heat convector fluid. When the load on the generator 5 is increased the valves are so operated that working medium is pumped from the storage vessel 35 into the circuit and the speed of the motor 61 increased. If the output power plant is controlled by means of a byepass pipe around the turbine or by throttling the current of working medium in the main circuit, the velocity at which the heat convector fluid is circulated may be regulated by the difference of inlet and exhaust pressures of the turbine.

Title: Clutch and brake control on road vehicles
IPC: B60T13/24
Filed: 1919-11-05
Abstract: 162,013. Thomas, J. G. P. Nov 5, 1919. Pneumatic transmission. -In means for actuating brakes and clutches on motor road vehicles by a power cylinder connected to the induction pipe of the engine, a valve connecting the cylinder to the atmosphere is controlled by the cylinder piston as well as by the control handle or pedal ' so that the degree of application of the brake or clutch depends upon the movement of the handle or pedal. The tubular valve rod 2 provided with a pedal 1 slides in the piston rod 3 and is urged upwardly by the spring 4 so that normally the cylinder is open to atmosphere through the apertures 15, 16 in the rod and a valve 17 controlling the communication of the cylinder with the in. duction pipe of the engine through the port 20 is held closed by the rod 14 provided with an enlargement 13 for engagement with the rod 12. The valve 17 is constantly urged downwardly by a spring or as shown by connecting the chamber 18 to the induction pipe through a port 19. When the pedal is depressed the valve 17 is first opened and then when the aperture 15 has been closed the piston 6 is moved downwardly and actuates the brake or clutch through the collar 8 and lever 7. The movement of the piston rod 3 with respect to the rod 2 partly uncovers the aperture 15 so that the movement of the piston is stopped. If the pedal is further depressed the aperture 15 is again closed and the piston is further moved. If the power fails, the brake can be applied by the direct movement of the piston by the pedal when the spring 4 is compressed.

Filed: 1971-06-11
Abstract: 1395491 Colour television EMI Ltd 30 May 1972 [11 June 1971] 27399/71 Heading H4F In a PAL colour television receiver which includes a switch 2, Fig. 1, which selects only alternate lines of chrominance information (or routes alternate lines through different channels), the phase of the demodulating oscillations from oscillator 12 applied to the demodulator 11 for the R-Y component which alternates in phase from line to line is controlled 21, 19 in dependence upon the phase of operation of switch 2. Switch 2 and burst gates 15 and 20 are operated in response to line flyback pulses at terminal 16, and the colour bursts from gate 15 (which alternate in phase Œ45 degrees about the -(B-Y) modulation axis at line frequency), control oscillator 12 which is connected in a phase-locked loop with discriminator 13 and reactance stage 14. The output of oscillator 12 which is in phase with the + (R-Y) modulation axis is compared with the separated bursts from gate 20 in phase discriminator 21, the output of which is used to control the state of switch 19 which passes the oscillations from oscillator 12 either directly (for selected even lines), or via a 180 degree phase shifter 18 (for selected odd lines), to the R-Y demodulator 11. In addition the output of discriminator 21 may be used to control a true adjustment circuit 9 in dependence upon whether the odd or even lines of chrominance information are selected (delay line 7 repeats each selected line for the subsequent line period). If the switch 2 selects even lines then switches 19 and 26 are held in the positions shown, but if switch 2 trips and selects instead the odd lines then the waveform from discriminator 21 changes and throws both switches 19 and 26 to their other positions. Phase locked loop 12-14 may be replaced by a passive oscillating circuit. A fixed phase shift is preferably included in one of the input lines to discriminator 21 so that the compared signals are in phase or in phase quadrature. Burst gate 20 may be connected to the other end 8 of the delay line 7, or to the other terminal 3 of switch 2, and it may be controlled to pass only every nth burst. In a second embodiment, Fig. 2, the demodulating oscillations from oscillator 33 (i.e. oscillator 12 in Fig. 1), are fed via phase shifting circuits 35 ( -45 degrees) and 36 (+45 degrees) to demodulators 32 and 31 respectively or vice versa in dependence upon the phase of operation of switch 28, i.e. the phase discriminator 44 holds open AND gates 40 and 42 or does not inhibit gates 41 and 43. A hue adjustment circuit of the type shown in Fig. 1, may be included in this embodiment.

Title: Method of production of articles having relief or recessed surfaces, bearing inscriptions or other representations, from sheet material
IPC: B29C61/02
Filed: 1950-11-10
Abstract: A pattern for use in the production of a series of articles of moulded or pressed sheet material having similar relief or recessed surfaces is formed by making a master sample by shaping a sheet of thermoplastic material, applying the required inscriptions or lines &c. to the surface and subjecting the sample to heat while resting it on a smooth surface whereby the sample is caused to collapse to substantially its original sheet condition. Copies of the collapsed sample may be produced by printing &c. upon sheets of the same or similar thermoplastic or a thermo-setting material, and the printed sheets pressed singly between dies of a shape and dimension corresponding to those of the master sample.  The master sample may be formed of polyvinyl chloride and shaped by pressing while hot between the dies to be used to form the final articles, or the sample may be produced by hand and used as a mould to form the dies.  A printing block is usually prepared from the collapsed master sample and used to produce the copies.  The master sample after resuming the flat condition may be subjected to light pressure with a sheet of glass or the like.  The starting sheets for the samples are usually flat, but may have other shapes, e.g. conforming to sections of a spherical surface so that the finished articles may be assembled to form a globe.  Suitable inks for use on the sample comprise or include as a component polyvinyl acetate having a solvent penetrating action on the surface of the sheet.  If the master sample is made of transparent material the copying of the distorted pattern may be effected by photographic projection.
