Title: Improvements in the steering mechanism of power propelled road vehicles
IPC: B62D7/22
Filed: 1925-10-03
Abstract: 263,555. Lanchester, F. W., and Lanchester's Laboratories, Ltd. Oct. 3, 1925. Non-reactive steering- mechanism. - Relates to hydraulic steering damping-mechanism of the kind in which a dashpot is provided with valves released by the steering-shaft, and comprises mechanism embodying a pair of primary and secondary valves, the primary valves being operated by the steering-shaft and admitting liquid to cylinders controlling the secondary valves, the passage for the liquid taking place by way of the secondary valves. The road wheels are steered by means of an arm 7 secured to a piston or vane a which works in a segmental chamber 15 and is loosely mounted on the operating shaft c connected to the steering hand-wheel (not shown). An arm d is fixed on the shaft c and works with a small amount of lost motion in a recess in the piston a.. A small amount of leakage past the piston is permitted, either through an adjustable passage or by making the piston a loose fit, but apart from this the piston is normally locked against movement in either direction. When, however, the shaft c is operated, the arm d thereon is moved (say) to the right (Fig. 2) and bears against a double primary valve e, f, closing the valve e and opening the valve f. Liquid can now flow from the right-hand side of the piston through the valve f to the under-side of a piston m which is pressed upwards and lifts a spring-pressed secondary valve n from its seat. As the arm d presses against the side of its recess the piston can move freely. liquid now passing from the right-hand side through the valve n, passage g, and the lefthand secondary valve n (not shown) which it lifts against its spring. The left-hand primary and secondary valves (not shown) are similar to the right-hand valves. An intermediate valve may be provided between each primary and secondary valve.

Abstract: 829,837. Boring-heads. BRINEY MANUFACTURING CO. Aug. 6, 1957 [Aug. 6, 1956], No. 24719/57. Class 83 (3). A boring-bar comprises a cutter-slide 30 adjustable in a transverse slot 12 by a shaft 40 intersecting the slot and having an eccentric control-part 52 bearing in the slide. The eccentricity of part 52 in relation to the ends 48, 50 of the shaft, located in bearings 22, 24 in the walls 14, 16 of the slot, is of the order of a few thousandths-of-an-inch, permitting the use of a single pre-loaded ball-bearing surrounding the ,three parts 48, 50, 52 of the shaft 40. The bearings 22, 24 are press-fits in the walls 14, 16, and the bore of bearing 22 is greater than that of the opening 38 in the slide, which is greater than that of bearing 24, permitting the insertion of the shaft 40, the sections of which have different diameters corresponding with those of the bearings 22, 24 and the opening 38, bearing- cage 63 and ball-bearings 64, through the larger bearing 22. A cup-spring 60, engaging the bearing 24 and clamped to the shaft 40 by a screw 54, presses the head 42 of the shaft against bearing 22. Key-holes 69 and a socket 68 in the head 42 provide for adjustment of the shaft against a scale 44 on the head 42 and an indexmark 46 on the bar. Springs 36 press the slide against the wall 16, and a spring-loaded plunger 74 in a passage 70 in the bar pivots the slide about the eccentric 52, to engage an adjustable screw-threaded stop 76 on the slide against an end-wall 81 of the slot 12.

Title: Improvements in devices for the automatic control of jigs for washing coal, ore, or any other products
IPC: B03B5/24
Filed: 1947-09-10
Abstract: 675,467. Jigs. PREPARATION INDUSTRIELLE DES COMBUSTIBLES. Sept. 10, 1947 [March 23, 1946], No. 24859/47. Class 82(ii) [Also in Group XXIX] In an automatic control device for the discharge of the larger pieces separated in coal &c. washing jigs 1, Fig. 1, e.g. a filter bed jig, one or more air cocks 34 and/or traps, follow the movement of a float 9 connected to a distributing plug valve 17, Fig. 2, which supplies pressure liquid to a servo-piston 28 actuating the cock. A piston 2, Fig. 1, causes water to oscillate through a foraminous plate 3 inducing the larger pieces forming the layer 5 to pass through the plate. When the layer reaches a predetermined minimum thickness, the float 9 opens the cock 34, thus permitting the water to oscillate in a chamber 7 which offers little or no resistance thereto, so that oscillation through the plate and therefore discharge of the coal is reduced to a minimum. Movement of the piston 28 effects rotation of the distributing value body 25, resetting the valve, so that for each position of the float, there is a corresponding position of the cock 34, and hence, a corresponding discharge of coal. In a coarse grain jig, the float 44, Fig. 5, is disposed in an open tube 45, and is subject to the oscillations of the water. As the float rises, due to an increase in the thickness of the layer 36, it opens the air cock 40, and the water oscillates freely in a chamber 39 withdrawing the pieces forming the layer 36, between lips 42, 43. When the layer reaches a minimum thickness, the float falls and closes the cock. Flaps 47, 48 may be moved to open or close the passage between the lips by the servomotor opening the air cock, or by a separate servomotor. In a modification, servo-pressure liquid is supplied continuously to both sides of the piston 28, and the float rod carries a cam which controls two exhaust valves, so that the space beneath the piston is exhausted when the float falls and vice versa. In a further modification, an abutment on the float rod actuates a cam to control the exhaust valves.

Abstract: 266,014. Simpson, C. H. Oct. 7, 1925. Feed motions.-A feeding mechanism for use in machines (e.g. slicing, stamping, punching, sawing, and other repetition machines) in which a variable intermittent feed motion is required, is of the type in which a slidably mounted bar, reciprocated longitudinally by a cam and returning-spring, is coupled to the intermittently moving feed member by ratchet mechanism.

Title: Improvements in or relating to electromagnetic apparatus of the kind which includes a thermionic valve control circuit

Abstract: 690,441. Automatic frequency control systems. GENERAL ELECTRIC CO., Ltd., and WATKINS, T. B. Oct. 10, 1951 [Oct. 13, 1950], No. 25029/50. Class 38 (iv). [Also in Group XL (c)] The Figure shows a frequency control system for a V.H.F. oscillator of the type described in Specification 690,442, in which a control voltage is derived from a phase-sensitive device 3 to control two differential relays 1, 2 which respectively control the operation of a motor in a forward or reverse direction, the motor being used to tune a resonant cavity which determines the oscillator's frequency. The variable control voltage from device 3 is applied in series with a stabilized voltage from across resistor 14 to the grid of a cathode follower stage 13 so that it is effectively applied to the grid of valve 22. Diode 33 conducts only when the voltage across resistor 21 falls below that at the tapping-point of potentiometer 29 which occurs at all negative values of the control voltage. The differential relays 1, 2 have twice the number of turns on windings 4 and 7 than on windings 5, 6 and when the control voltage from device 3 is at zero, potentiometer 29 is set so that equal currents pass through windings 4 and 7 and both relays remain unoperated. When the control voltage increases positively the voltage across the cathode resistor 21 and thus at the grid of valve 10 increases and there is an increase in current in winding 4 of relay 1. The presence of the common cathode resistor 23 causes a consequent increase in current in windings 5, 6 and 7. When the control voltage reaches a value approaching that at which valves 8, 9 and 11 would be rendered non-conductive, relay 1 operates; if now the control voltage is reduced the current in winding 4 is reduced and that in winding 5 is increased so that relay 1 rapidly releases. When the control voltage becomes negative diode 33 conducts so that the voltages of the grids of valves 8, 9 and 10 are reduced whilst that of valve 11 remains constant so that at a predetermined negative control voltage relay 2 operates and rapidly releases when the control voltages increase slightly in a positive direction.
