Title: Improvements in and relating to power assisted steering, particularly for motor vehicles
IPC: G01P15/18
Filed: 1969-12-18
Abstract: 1281185 Power assisted steering mechanism ZAHNRADFABRIK FRIEDRICHSHAFEN AG 18 Dec 1969 [21 Dec 1968] 61804/69 Heading B7H A power assisted steering system is of the kind having a servo pump for delivering a pressure medium, a valve for controlling the pressure medium, a steering gear casing subdivided by an hydraulic piston into two pressure chambers, a rocker shaft mounted in the casing, and a recirculatory ball nut mounted for rotation in the piston and co-operating with a worm by balls engaging the nut. The ball-nut 13, Fig. 1, has a driving member 14 with an end 15 engaging a bore 16 of a control valve 17 disposed transversely of piston 7. The valve 17 has a member 22, Fig. 6, guided in a bush 27 and a radial bore 25 engaging the end 15 of the member 22. Reaction pistons 30, 31 are disposed in discs (32), (33), Fig. 5 (not shown), secured to piston 7 by screws 32, 33, Fig. 6. A centring device 45, Fig. 5, fixes the position of the nut 13 and control valve 17 in the central steering position which may be adjusted by grub screws (51), (52), Fig. 8 (not shown). Pressure medium is fed to the valve 17 through grooves, 55, 56, Fig. 6, communicating through bores (57) (58), Fig. 4 (not shown), in the piston. Inlet and outlets 60, 61, Fig. 6, are provided in the casing 3 to connect with the grooves 55, 56. Pressure medium flows in one direction to pressure chamber 8 through the valve 17, Fig. 5, through a groove 23 in member 22, a channel 68, a chamber 69 and bores 21 in a ring 20 and in the other direction through a groove 24, channel 71 to pressure chamber 9. When a steering wheel on a splined shaft 1 is stationary pressure medium flows through the valve 17 between inlet 60 and outlet 61. However, when a steering movement is effected worm 2 rotates and by means of the balls 18 moves the ball nut 13, and piston 7, e.g. downwards, Fig. 1, the pressure medium flows into chamber 9 and from chamber 8. The pistons 30, 31, Fig. 5, are differentially loaded to produce differential pressure on valve member 22 so that the driver experiences "feel" associated with a mechanical steering system.  In another embodiment, Fig. 2 (not shown), a piston (107) has a blind base and the ball nut (113) is above rocker shaft (111). In a further embodiment, a short rocker shaft (11<SP>1</SP>), Fig. 9 (not shown), has a sector (10<SP>1</SP>) projecting into a pressure chamber 9<SP>1</SP>. A modified control valve (124), Fig. 11 (not shown), has reaction pistons (136), (137) adjustable for centring by set screws (140), (141) having eccentric portions (142), (143).

Title: Switching regulator for a television apparatus
IPC: H04N3/16
Filed: 1979-09-05
Abstract: A controllable switch 14 is coupled to a source 10 of unregulated direct voltage and in a closed loop with a filter inductor 16 and a storage capacitor 18 and has its on-off state controlled at the horizontal deflection rate, e.g. by deflection circuit 22, to control the voltage across the capacitor. A diode 24 is coupled with the filter inductor and storage capacitor to form a second series circuit through which current can continue to (ow in the inductor 16 when the controllable switch is opened. The controllable switch is used to regulate the voltage applied to the horizontal deflection circuit 22. A turn-off winding couples a retrace pulse to the switch 14 during each horizontal retrace interval in preparation for the following regulation interval. The current variations in the filter inductor cause the diode to become nonconductive at times, thereby changing the average time during which the filter inductor parallels the deflection winding and varying the retrace pulse duration in such a manner as to improve the regulation. <IMAGE>

Title: An improved device for measuring the deflection of a concrete slab of a road
IPC: G01D5/04
Filed: 1980-01-08
Abstract: A device for measuring the deflection of a concrete road slab 10 when a load passes over it comprises two rigid rods 1, 2 so secured together that they are constrained to move relative to one another only in the direction of their lengths. A spindle 6 is so gripped between the rods 1, 2 that, when such relative movement occurs, the spindle is caused to rotate. A part of the spindle 6 protruding from between the rods 1, 2 carries a pointer 7 which indicates on a fixed scale 8 the angle of rotational movement of the spindle and/or a direct reading of the deflection. In operation a peg 12 is hammered into the ground through a hole 11 in the slab 10, and the rod 1 is fixed to it, a plug 15 making frictional contact between the rod 2 and the slab. Movement of the slab downwardly under test load then causes relative movement between rods 1, 2 and movement of the pointer. <IMAGE>

Title: Build-up Welding on Rotating Workpieces
IPC: B23Q15/08
Filed: 1981-02-10
Abstract: Apparatus for controlling the progress of build-up welding on rotating workpieces, in particular large diameter shafts, makes use of one or more welding heads 16 arranged to deposit one or more continuous weld beads on a rotatable workpiece 11. A drive motor M1 is used to produce rotation of the workpiece and a feed motor M2 to produce axial feed movement of the welding heads 16 relative to the workpiece 11. A sensor 15 measures a value corresponding to the prevailing diameter of the workpiece. The rotational speed of the drive motor M1 and thus of the workpiece 11, is controlled in accordance with the sensed diameter of the workpiece so as to hold the peripheral speed of the workpiece and thus the length of bead deposited per unit time, substantially constant. The rate of axial feed of the welding heads 16 relative to the workpiece 11 is controlled in dependence on the rotational speed of the workpiece so as to produce a continuous weld build-up over the length of the workpiece. Methods of controlling the progress of build-up welding are also disclosed. <IMAGE>
