Title: Hydraulic follow-up for vehicle steering systems
IPC: B62D12/00
Filed: 1967-05-12
Abstract: 1,141,117. Steering articulated vehicles. CATERPILLAR TRACTOR CO. 12 May, 1967 [1 Feb., 1967], No. 22130/67. Heading B7H. Steering of a vehicle having articulated portions 12, 13 pivoted at 11 is by double-acting cylinders 14, 16 and a follow-up device comprises a master cylinder 48, connected between portions 13 and pivoting linkage 19 to detect the articulation, and a slave cylinder 47 having its ends hydraulically coupled with the respective ends of the master cylinder through lines 53, 56 containing throttles 54, 57, the pressure fluid being supplied to the cylinders 14, 16, 47 from a pump 22 via a valve 23 controlled by a steering mechanism 25. The mechanism 25 comprises a steering wheel 29 connected by splines 34 to a shaft 33 mechanically connected to the valve 23. The shaft 33 is threaded at 37 and has a sleeve 38 mounted thereon which engages a gear sector 39. Rotation of wheel 29 from a neutral position causes axial movement of shaft 33, since sector 39 is held in position, and actuation of valve 23 through linkage 43, 24 allows pressure fluid into cylinders 14, 16 for steering. Detection of the articulation causes piston 49 to move in cylinder 48 and hence movement of piston 67 in cylinder 47. Pistonrod 64 via link 41 therefore tends to rotate sector 39 so that when the wheel 29 ceases to be rotated shaft 33 is re-centralized and valve 23 returns to its closed position. In the event of rupture of an hydraulic line a band brake 66 prevents movement of piston 67 in the slave cylinder. In a modification, Fig. 2 (not shown), spring means are provided to centralize the slave piston in event of a fluid leakage. In a further modification, Fig. 3 (not shown), a blocker valve is provided between the master and slave cylinders which isolates these cylinders from each other except during actuation of the master cylinder.

Title: Improvements in or relating to television, telecinematographic and like systems
IPC: H04N7/00
Filed: 1934-07-31
Abstract: 436,108. Television. WEST, A. G. D., and BAIRD TELEVISION, Ltd., 58, Victoria Street, Westminster. July 31, 1934, No. 22289. [Classes 40 (iii) and 40 (v)] Separately generated synchronizing and picture signals 9, 11, Fig. 2, alternately modulate a carrier wave in such a way that they lie on opposite sides of a line of demarcation 12, while "picture white" corresponds to lower carrier wave amplitudes than "picture black." The synchronizing signals may be in the "whiter than white" or " blacker than black " direction. Picture signals generated in a cell 19, Fig. 7, are amplified at 24 and applied across resistances 27, 32 in the grid circuit of valve 25. Simultaneously, the picture signals are fed over condenser 28 to a rectifier 29 to vary the current through resistance 32, thus replacing direct current components lost in the amplifier 24. A commutator 34 shortcircuits the resistances 27, 32 at the end of each line so that synchronizing signals, separately generated in a cell 38, may be applied to the grid of valve 25. A second commutator may produce a longer interruption at the end of each picture. In a modification, Fig. 8, the picture signals are not corrected for loss of direct current components and the commutator is replaced by a valve. The picture signals from the amplifier 24 are applied to the grid of valve 46 over a condenser 26 to produce variations across the resistance 27. Synchronizing signals are also applied over line 45 to the grid of valve 46 and make it highly positive to produce a large potential across resistance 27 and make the bias on valve 25 more negative. At the same moment the synchronizing impulses are applied to valve 25 over the valve 44. The synchronizing impulses may be of the form shown in Figs. 3, 4, 5. Specifications 269,834, 275,318, and 320,639, [all in Class 40 (iii)], are referred to.

Title: Improvements in devices for cutting off the current of electric lifts or hoists whenthe gates or doors are open
IPC: B66B13/22
Filed: 1919-09-11
Abstract: 153,146. English Sewing Cotton Co., and Bennett, A. Sept. 11, 1919. Lift doors, locking and operating.-Relates to locking and operating devices for electric lift and hoist gates provided with switches forming part of the motor circuit. Two similar bars A, U having a cranked end are centrally pivoted on brackets B on the lift well and cage, respectively, and are engaged by runners f on the respective gates. When the landing gate G is closed the runners raise the cranked end of the bar A so that a projection K on the bar tilts a pivoted cam-shaped lever k<2> out of the way of a stop e on the cage gate E. The cage gate can then be closed and the corresponding raising of the cranked end of the bar C brings together the contacts e on the bar and the switch contacts l<1> on the cage and completes the circuit. The cam-shaped lever k<2> prevents the closing of the cage gate and circuit until the well gate has been closed. If a landing- gate is opened after the cage has moved away, a projection b<1> on a slide b carrying the contacts l is struck by the lever k<2> when the cage next passes the landing, thus breaking the circuit and stopping the cage. The cam-shaped lever may be replaced by a pair of pivoted projecting levers. When a landing gate only is employed, the switch contact is mounted on the bar A. Specification 137,611 is referred to.
