Abstract: 426,146. Converting. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Allgemeine Elektricitõts-Ges. ; 2, Friedrich Karl-Ufer, Berlin) Dec. 4, 1933, No. 34062. Convention date, Dec. 2, 1932. [Class 38 (ii)] In converting A.C. to D.C. or vice versa by means of grid-controlled discharge devices 10, 20, 30 associated with rotary switches 41, 4<11> whereby the discharge paths are relieved of voltage during the non-conducting periods, the grid potentials are distributed by rotary switches 40v, 40n operating in fixed phase relationship with the switches 4<1>, 4<11> in the discharge circuits. The grid potentials are derived from delta-connected resistances 5<1>, 5<11>, 5<111> fed from the secondary windings 1, 2, 3, of the main supply transformer. The two groups of switches are driven from a common synchronous motor the stator of which may be angularly adjusted to effect voltage regulation of the converter by adjusting the moment at which the discharge is initiated at each cycle. Phase shift of the grid voltages derived from the resistances 5<1>, 5<11>, 5<111> may be effected by providing phase-shifting transformers to determine the phase of the potentials at the terminals 11, 2<1>, 3<1>, or by shifting the tappings on the resistances.

[Also in Division G3] In a plain bearing, a journal 2 in a sleeve 1 is subjected to a force applied at right-angles to the direction of action of the load carried by the bearing. In an embodiment the force is pressurized lubricant and is applied at A or B, Fig. 2, according to the direction of rotation of the journal. The force is varied by an electric inductive sensing device 107 which is connected through an amplifier 106 to a lubricant distribution valve 103 controlled by an electromagnetic mechanism 105. The lubricant is pressurized by a pump 108. In another embodiment the force is applied by means of pressure developed hydrodynamically. Lubricant is supplied to the clearance between the sleeve and the journal by a pump 101, Fig. 3, and a wedge of lubricant is formed between the rotating journal 2 and a member 10 which is pivoted about the sleeve at 11 and is held against an adjustable stop 12 by a spring 16. The wedge of lubricant becomes pressurized and provides the required force. The stop 12, having an integral piston housed in a cylinder 14 formed in the sleeve 1, is adjustable by means of a sensing device &c. as previously described. Pressurized lubricant supplied at the regulated pressure through a pipe 15 to displace the piston 13 and thus adjust the capacity of the wedge of lubricant so as to vary the hydrostatic pressure generated. In an alternative construction an extension 30, Fig. 4, of the sleeve has a flexible portion 31 and forms a fluid-tight engagement with a wall of a cavity 32 formed in said sleeve. Lubricant is supplied at the regulated pressure to the cavity 32 to displace the extension 30 of the sleeve and so adjust the hydrostatic pressure. Specification 877,233 is referred to.

[Class 69 (ii)] [Also in Groups XXXIV and XXVI] A hydraulic receiver, e.g., for actuating brakes, comprises small and large pistons 14 and 4 adapted to operate in succession, the small piston 14 being connected with the part to be actuated and mounted in a bore 13 in the large piston 4 which works in a cylinder 2 and is subject to the return action of resilient means such of a spring 7. Communication between the cylinder 2 and bore 13 is controlled by a check valve 9 initially unseated by engagement with the end of cylinder 2. Fluid is forced into the cylinder 2 and exerts a pressure on both pistons, but initially the pressure is insufficient to overcome the spring 7 so that at first 'the small piston 14 only is displaced. When the resistance to movement of piston 14 increases, as when the slack in the brake mechanism is taken up, the fluid pressure increases until it is sufficent to overcome spring 7. The large piston 4 then commences to move outwards, the check valve 9 immediately closing so that the two pistons move in unison to apply an increased force. In a modification a rubber or other elastic liner interconnects the large piston and cylinder 2. The return spring 7 is then omitted.
