Title: Improvements in flash-light apparatus for indicating the magnitude of the torque or turning effort in rotating shafting
Filed: 1919-09-04
Abstract: 166,250. Gibson, J. H., and Bovis, R. R. Sept. 4, 1919. Indicating, optical devices for - Relates to flash-light apparatus of the type described in Specification 13096/07 for indicating the magnitude of the torque in a rotating shaft, such apparatus comprising two cylindrical screens provided with slots fixed to the shaft at points some distance apart, together with a fixed lamp and slotted mask located within the inner screen, and, according to the present invention, the arrangement is such that the slot in the lamp mask is located much nearer to the axis of the shaft than the slot in the inner screen, while the radial distance between the slots in the screens is relatively small. A shaft A has clamped to it two cylindrical and concentric sleeves or screens B, C each formed in halves bolted together, the outer screen having a conical projection as shown, and both screens being clamped to the shaft at a fixed axial distance apart by set screws in the same plane as sharp locating flanges b<2>, c<2>. Slots b<1>, c<1> parallel to the axis of the shaft are formed in the screens, and a third slot d' in the mask d<2> of a fixed lamp D located inside the sleeve B. The finder F comprises a tube having a diaphragm with small central opening, and moves over a quadrant guide E about the slot d<1> in the lamp mask as centre, carrying also a vernier f<1> moving over a scale f<2>. The overhanging end of the screen C is provided with rollers which bear on a turned portion of the inner sleeve. When the shaft is not transmitting torque, two readings are taken at the finder F, when the light is just visible and again when it just disappears. 'The mean of these two gives the zero reading. Similar readings are taken when under torque and the mean taken. The difference between the two mean readings obtained in this manner is a measure of the angis of torque, the sine of the angle moved through by the tinder being proportional to the angle of torque when the angles are small. The slits may be in thin metal sheets adjustably mounted and one may be displaced through a, known angle relatively to the other by means of a micrometer screw for purposes of verification. To fix the parts in correct relative position, the bracket G carrying the lamp, mask, finder-guide and scale is provided with a facing, and a sheave or strap fitting over the shaft is provided with a similar facing to which the facing on the bracket is belted. After the bracket is set in this manner, it is bolted to a second bracket J fixed to the bed-plate, and the strap is removed, but may be used occasionally to check the setting.

Title: Power brake system
IPC: B60T8/58
Filed: 1964-05-29
Abstract: 1,027,088. Fluid-pressure brakes. BENDIX CORPORATION. May 29, 1964 [June 12, 1963], No. 22339/64. Heading F2F. In a fluid-pressure brake system for a road vehicle or aircraft, including a power and brake actuator, e.g. a servo-operated master cylinder, the operation of the actuator is adapted to be made intermittent, i.e. to provide intermittent braking pulses, upon operation of an electrical device by inertia means responsive to rotation of a wheel or wheels of the vehicle, so as to prevent wheel locking, there being also a holding circuit energized by depression of the driver's pedal whereby the intermittent braking is maintained until the pedal is released. As shown, front and rear wheel brakes of a road vehicle are operated by respective master cylinders 26, 28 each having a vacuum servo 10, 12, respectively, of the vacuum-suspended type. Vacuum is supplied to the vacuum chamber of servo 10 directly by a pipe 18, and to that of servo 12 by a pipe 34 via a solenoid valve 36 adapted when operated to shut off the vacuum and admit air from an inlet 38. The power chambers of the two servos are connected together by a pipe 24 and are controlled by a common valve of conventional type associated with the servo 10 and operated by a pedal 14. The solenoid valve 36 is intermittently operated, for pulsing the output of master cylinder 28' by an electric circuit comprising a solenoid operated relay whose coil 90 is energized initially by an inertia switch 40, on the occurrence of excessive deceleration of the rear wheels, and is held energized via hold contacts 92, 106 and a switch 112 which is closed so long as the pedal 14 is depressed, to close contacts 100, 108 which complete a circuit via a thermal cut-out switch 110 to the solenoid valve 36. When this happens, the bimetallic strip of the switch 110 opens and closes the circuit periodically to provide the desired intermittent operation of the rear wheel brakes. The inertia switch 40 comprises a flywheel 44 rotated via a pin 48 engaging ratchet teeth 50 rotated by a driving cable 42, the pin 48 riding up the teeth 50 on excessive deceleration to cause pivoting of a switch arm 58 against the resistance of springs 64, 70 to close contacts 84, 86. The compression of spring 70 is adjustable by the driver moving a lever 82 connected by a cable to a lever 74 acting on the spring, so that the switch is adjustable according to road conditions.
