Title: Automatic Control System
IPC: F01D17/26
Filed: 1967-06-16
Abstract: 1,154,947. Fluid-pressure servomotor systems. TEXACO DEVELOPMENT CORP. June 16, 1967 [June 30, 1966], No.27839/67. Heading G3P. A system for controlling flow, pressure, temperature &c. comprises a measuring unit 14 which transmits a signal proportional to the measured variable to a bias relay 17 where the signal level is reduced and transmitted via amplifier 21 to a comparator 31. The latter compares the signal with a set point signal from control unit 27 and provides an output signal only when the input is less than the set point signal. This output signal is transmitted to the control unit via a restriction 37, booster relay 41 and manual-automatic station 47. To provide bumpless transfer between manual and automatic modes, the output line communicates with line 39 through restriction 55. When the input to comparator 31 is greater than the set point, the signal in line 39 leaks away through restrictor 37. A capacitor 43 determines the RC time constant governing the build-up and decay of the signal in line 39. The system can be pneumatic, hydraulic or electrical. A typical bias relay or booster relay Fig. 2 (not shown) has a diaphragm (61) responsive on one side to signal pressure in line 15 and to the tension of spring (91) and on the other side to the output signal pressure in chamber (80). The latter is less than the pressure in line 15 by an amount dependent on the tension in spring (91). Valve (89) on diaphragm (61) controls the supply to chamber (80), the latter communicating with outlet chamber (79) which is supplied and exhausted respectively by valves (82, 86) on stem (83) controlled by double diaphragm (65, 67). The amplifier Fig. 3 (not shown) has a disc positioned by input signal bellows (101) to control the leak-off from nozzle (98). Bellows (103) provides a feedback signal to the disc. The comparator Fig. 4 (not shown) has a stack of four inter-connected diaphragms with a supplyexhaust valve (158) located between the two inner diaphragms to connect outlet (163) to supply (164) or exhaust (35a) according to whether the set point signal in chamber (143) exceeds or is less than the input in chamber (131).

Title: Improvements in or relating to the formation of mosaic screens as are utilised in television pick-up tubes
Inventor: WARDLEY JOHN
IPC: H01J9/233
Filed: 1954-09-28
Abstract: 800,251. Television pick-up tubes. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Sept. 13, 1955 [Sept. 28, 1954], No. 27930/54. Class 39(1). In a method of forming a mosaic screen on an insulating support and a stabilizing mesh grid close thereto, the grid is mounted to be movable in position towards the screen and a stencil is placed between the grid and the screen for metal to be evaporated through it to form the mosaic, the stencil being afterwards removed and the grid moved closely adjacent the mosaic screen. The optical window 2 of the tube carries a signal plate 3 and a di-electric layer 4. A stencil 14 is supported close to the layer 4 from a hook 15. Two rods 5 extend from the outer parts of the window 2 and support a double frame 8, 9 across which is stretched a mesh electrode 7. The rods 5 pass through circular apertures 12 in the frame 9 and leaf springs 13 welded to the frame grip the rods and lock the frame against movement away from the target after evacuating the tube and depositing bismuth-silver alloy through the stencil held close to the target by the electrostatic force of a high potential on the signal plate, the potential is removed and the stencil unhooked by external magnetic means and allowed to drop away under the grid frame 9 and be manipulated into a side tube which is sealed off and removed. Oxygen and caesium are then introduced and sensitize the mosaic, and the tube is tilted and tapped to bring the grid 7, 8, 9 close to the target from which it is held spaced by distance pieces 11 and locked by the springs 13. Instead of a single mesh, a double mesh may be used comprising a stabilizing grid and an ion trap grid with a ring electrode 17 between for decelerating and directing the beam, Fig. 4. Ceramic rods 16 space the grids and support the tubular electrode, and the latter is connected by a spring 19 to an electrical contact on the window 2 when the double mesh is in position ; one aperture in each frame 9 is just large enough to pass the rods and is provided with leaf springs and the other aperture gives ample clearance, the corresponding apertures of each frame being on opposite sides. The large aperture in the ion trap mesh frame is provided with a metal cup 21 to prevent distortion of the field by the rod, and a strip 22 at the bottom of the ion trap frame projects to prevent deposition of metal on the window 2 during evaporation of the bismuthsilver. Specification 657,666 is referred to.

Title: Self-propelled vehicles having two or more driving axles
IPC: B60T7/08
Filed: 1928-09-29
Abstract: 323,471. Morris Commercial Cars, Ltd., Hamill, W. W., and Jenkins, W. H. Sept. 29, 1928. Force-transmitting mechanism.-In vehicles. with three or more axles, two of which are driving axles having elastic torque reaction gear, the hand-brake mechanism is so arranged that when this brake is operative the return movement of the torque reaction gear as the vehicle comes to a standstill tends to reduce the load on the brake connections and thus avoid locking the hand-brake in the " on " position. In the construction shown applied to a vehicle having two rear driving axles a, b the brake cams are situated rearwardlv of the rear axle band forwardlv of the foward axle a, and' are operated by arms c', c respectively connected by a push-rod e<1> and a tension rod e to a common operating means comprising a lever j actuated by the hand lever n. The lever j is pivoted' at u to a clip or bracket r clamped on a frame cross-member i receiving the reaction from the torque members which may incorporate coil compression springs and are connected to the axle casings. When the hand brake is applied the brake cams are rotated in the opposite direction to that in which the wheels are rotating, with the result that the rotary movement of the axle casings due to the brakes and to the yielding of the torque gear tends to increase the braking pressure, while when the vehicle stops the return movement of the casings, due to the reaction of the torque gear, releases the undue pressure on the brake connections so that the brake can readily be released by hand.
