Abstract: 388,418. Hydraulic transmission of power. BURGESS, A. F., 10, New Court, Lincoln's Inn, London.-(Barnes Corporation, J. S. ; Rockford, Illinois, U.S.A.) Aug. 18, 1931, No. 23244. [Classes 69 (ii) and 135.] A hydraulic actuator system comprising a number of actuators has means for supplying pressure liquid to one actuator, the movement of this actuator supplying liquid to another actuator to effect its movement. The invention is described in connection with the automatic lathes described in Specifications 366,928 and 368,792, comprising a piston 60, Fig. 1, for oscillating a front tool carriage 46, a piston 72 for reciprocating the front tool carriage, and a piston 90 for reciprocating a rear tool carriage. Control valves 160, 162 are shown in Fig. 1 in their neutral positions, liquid supplied from a pump 150 returning through ports 194, 196 to a reservoir 146. When the valves are moved into the positions shown in Fig. 2 for obtaining a rapid forward traverse, liquid passes through a port 226 and line 228 to the cylinder 58, and the liquid forced from the other end of this cylinder by the piston 60 passes through a check valve 232, cylinder 236 and line 240 to a cylinder 88, where it actuates the piston 90. Liquid expelled by the piston 90 returns to the reservoir through a line 242, port 244, a passage not shown, and a line 206. During this action, a piston 250 is operated to engage clutching means for driving pumps 94, 94a. The valves 160, 162 are returned to neutral, and the pumps 94, 94a supply liquid for moving the pistons 60, 72, 90 at a feed rate. At the end of the stroke of the carriages, the valves 160, 162 are moved into the position shown in Fig. 3, for effecting a rapid return traverse. The piston 250 is operated to put the pumps 94, 94a out of action, liquid passes through lines 242, 270 to return the pistons 90, 72 ; the piston 60 is returned by gravity aided by liquid passing through the valve 262 and line 266. Operating means for the valves 160, 162 comprises cranks 174, 176 which may be secured to a shaft 178, Fig. 4, by set-screws 180, and the shaft 178 may be actuated manually by a handle 158, or automatically by dogs on a slide 276 connected to the rear tool carriage; further at the end of the forward motion, a dog may act through a lever 308 to move a valve 312 to place a chamber 316 into communication with the reservoir through a port 318 and line 322, so that the valves are moved into the position shown in Fig. 3 by the pressure on their opposite ends. The valve 232 comprises a spring-pressed plunger 346, Fig. 5, preferably arranged in a liner 342, provided with a central passage 352, and radial ports 354, the latter being adapted to co-operate with an annular passage 358.

Abstract: 429,170. Moderating rolling and pitching. VINOGRADOFF, M., 3, Rue Marie, Paris. Aug. 22, 1933, No. 23389. [Class 113 (i)] Fins or balancing planes for moderating rolling or pitching have arms of unequal length and are pivoted on shafts housed in recesses in the hull below the water-line. The fins are free to oscillate within units fixed by stops fixed on the hull except as regards fluid brakes. The fin C balanced about the pivot D but having its centre of pressure forward of the pivot is mounted in the recess shown free to oscillate within the limits of the stops S. When the ship rolls, the fin assumes an extreme position and the increased resistance damps the rolling motion. At the extreme position, the stops open pivoted slats t<1>-t<4> and the reduced pressure initiates the return to horizontal. Arrangements are described for protruding the fins from the recesses when required, the recess when the fin is out of action being closed by the cover b<2>. As shown in Fig. 8 the oscillating movement of the fin C is damped by the dashpots H or M, N arranged as shown and connected to the arm E fast on the fin shaft D by the arms F or the rods of the cylinders J, K.

Abstract: 693,925. Exciting dynamo-electric machines for battery charging. METROPOLITANVICKERS ELECTRICAL CO., Ltd. Aug. 20, 1951 [Oct. 4, 1950], No. 24267/50. Classes 35 and 38 (iv). [Also in Group XXXVII] The exciter of a battery charging generator for vehicles has a field leakage path, the flux through which is varied by windings to control the output of the exciter, and so regulate the generator output so that it is not overloaded and the battery is not overcharged. The field winding 4 of the generator 1 is fed by the exciter 5 which is preferably of the construction described in Specification 681,403, and in the arrangement shown in Fig. 1, carries a pair of current responsive control windings 6, 7 selectively brought into operation by a battery voltage responsive relay 8. During charging, the battery voltage being low, the relay short-circuits winding 7 so that the excitation is controlled in dependence on the generator current in winding 6, thus limiting the generator output to its rated value. When the battery reaches gassing voltage, winding 6 is shortcircuited and the excitation is controlled by the battery current flowing in winding 7 so that the generator current is limited to the load current plus a trickle charge for the battery. In a modified form, the current responsive winding 7 is replaced by a voltage responsive winding connected in series with a resistor across the battery. This winding is shunted by a carbon-pile regulator responsive to the battery voltage. At low battery voltages this winding is virtually short-circuited by the regulator and is inoperative, the winding 6 limiting the generator current as before. At higher voltages the voltage responsive winding becomes operative to limit the battery current. Fig. 2 shows a construction of electromagnet for the relay 8. A permanent magnet armature 13 rotates between a pair of poles 11, 12 whose strength depends on the battery voltage exciting windings 9<SP>1</SP>. At a predetermined voltage the magnetic effect of the windings overcomes that of the armature and causes it to swing round through 180 degrees and so operate the contacts.

A method of forming a tyre band comprises the steps of preparing a belt-like assembly including a number of parallel cord layers bonded longitudinally stepwise so that no end edges thereof cross each other, and winding the assembly around a former drum 5 to provide an annular band. To provide a four-ply band, four rolls of ply material are fed under pinch rollers 21 on to conveyer belts 16 while separator sheets are wound on to rollers 15. Each roll of ply material is cut by a device 17 when the material has moved a certain distance along an adjoining conveyer 18. When the four layers 1-4 have been cut they are transferred by means of conveyers 18A on to another conveyer 20, so that the forward end b of the layer 2 lies a prescribed distance behind the forward end a of the layer 1, and the forward ends b, c, d of the layers 2, 3, 4 are similarly spaced. The four layers are bonded together by pressure rollers 25 as the conveyer 20 moves in the direction of arrow 26 in Fig. 5, and so delivers the four-ply assembly to the drum 5.
