Abstract: 885,945. Two-part couplings. NEIDECKER, R. May 26, 1959 [June 28, 1958], No. 17837/59. Class 38 (1). A double-ended socket contact A, B, Fig. 1, comprises a tubular casing 2, which may be of insulating material and the ends of which are turned over at 3 to slidably retain the ends of a number of circularlyarranged spring wires 1, said wires being clamped at the centre of the casing by a double conical ring 4 which imparts a bowed shape to the wires to form the sockets. One socket may be longer than the other and in the modification shown in Fig. 3 the casing 2 is dispensed with, the wires 1 being gripped at their centres between concentric rings 4a, 4b and retained at their outer ends by caps 5. Fig. 4 shows a double-ended plug C, D consisting of a rod surrounded by the wires 1 which are clamped in a groove at the centre of the rod by a ring 4 and secured to the outer ends of the rod by caps 3a. The ring 4 may serve to mount the contact in a plastic moulding as shown. Alternatively the double-ended plug C, D may be combined with a double-ended socket A, B, as shown in Fig. 5, the ring 4 serving to mount the contacts concentrically. The ring may be formed in two concentric parts which are insulated from each other thereby forming pairs of concentric contacts A, C and B, D, or the ring may connect the contacts together. The plugs and sockets may be of different lengths. Figs. 8 and 9 show another embodiment wherein groups of co-planar wires are arranged on opposite sides of recesses in an H-shaped insulating body 8 with their ends engaging notches 8b and centrally clamped at 8a. The body 8 may be elongated and have a number of contacts mounted therein to form multiple sockets.

Title: Improvements in or relating to the starting of direct current motors
IPC: H02P1/54
Filed: 1937-06-26
Abstract: 495,893. Control of D.C. motors. CANTIERI RIUNITI DELL ADRIATICO, CANTIERE MONFALCONE. June 26, 1937, No. 17848. Convention date, June 27, 1936. [Class 38 (iii)] Varying E.M.F.-To facilitate the starting of a D.C. motor M and its supply finally from a main D.C. generator Dp, an auxiliary generator Da also supplies current in opposition to the main generator and is gradually cut out as the motor speeds up, the auxiliary generator being then available for starting another motor. The two generators may be mounted on the same driving shaft and they are arranged during starting in series opposition so as to supply current to the motor through the upper contacts of switch Co. The arm of the rheostat Ra is then in its lowest or inoperative position, so that the field e of the auxiliary generator Da is fully excited. As the motor speeds up, the arm of the rheostat is raised slowly, thus gradually reducing the voltage of generator Da, the arm being then held in its raised position by electromagnet F. When the speed of motor M is high enough switch Co is operated to open its upper and close its lower contacts, thus cutting generator Da out, when electromagnet F is de-energized and rheostat arm Ra falls, cutting out the rheostat ready for starting another motor connected to the mains. The rheostat may be dispensed with and an opposed field winding for the generator Da may be connected across the motor M so that the generator Da is automatically cut out as the motor speeds up.

Title: Improvements relating to the filling of ampoules
Inventor: BLICK FRANK
IPC: B65B3/00
Filed: 1952-07-15
Abstract: 738,005. Ampoule filling machine. BOOTS PURE DRUG CO., Ltd. Sept. 30, 1953 [July 15, 1952], No. 17879/52. Class 81 (1). A machine for filling ampoules with a predetermined quantity of liquid is such that the ampoules are moved along a straight path at a substantially constant speed and a filler head comprising one or more filler nozzles is moved at a corresponding speed above the ampoules so as to permit the nozzles to descend into the necks of the ampoules to deliver a measured quantity of liquid, and after the filling is completed to be retracted, after which the filler head returns to the beginning of its travel ready for the next cycle. The speed of return of the filler head is preferably greater than the speed of advance. As shown, a filler nozzle 36 is raised by means of a roller 35 running in a horizontal track 28, moved in a vertical direction by cam controlled rocker arms (not shown), and is lowered under spring control. The roller 35 raises a push rod 37 connected to the filler nozzle 36, the rod 37 also serving to compress a spring 58 for operating a pump 52 for carrying out the filling operation, the member 54 of the spring mechanism thereafter remaining latched at 66 in the compressed position of the spring 58 until released by movement of the filler nozzle as the needle thereof enters the neck of the ampoule. A stop member 50 is provided to prevent the downward movement of the nozzle 36 and thus the subsequent filling operation when no ampoule is present. The stop 50 is actuated by a gripping device 80 having a pair of fingers 81 and 82 pivoted at 83 and 84 and provided with rollers 99 and 100 which engage the lower end of the nozzle 36, which is so shaped that when the nozzle 36 is in the raised position (as shown, Fig. 3), the rollers are close together and the grippers are open. As the nozzle 36 descends, the rollers 99 and 100 are forced apart and the grippers close. When an ampoule 3 is present, the projection 89 on the gripper finger 82 pivots about the neck of the ampoule causing the finger to move laterally in the slot 105 so as to release the stop 50, thus allowing the nozzle to complete its downward path and the filling operation to take place. After filling, droplet formation on the end of the needle is prevented by the suction produced in the flexible filling tube 109 by the release of the compression in the flexible tube brought about by means of a plate 115 secured to the top of the push rod 37.

Title: Improvements in or relating to shock absorbers
IPC: F16F9/28
Filed: 1929-06-13
Abstract: 332,364. Stevens, A. H., (Delco Products Corporation). June 13, 1919. Fluid-friction vibration-dampers. - In a vehicle shock-absorber a twoarmed rocking lever operates two pistons movable in cylinders enclosed in a casing each piston being operated positively in one direction and resiliently in the opposite direction. The two cylinders are inclined slightly to one another and form part of a casing adapted to be secured to the vehicle frame. The. shaft 38, which is oscillated bv means of a connection to the axle, carries a two-armed lever 45 the ends of which force the pistons 51, 52 downwardly by means of hardened steel ends 48 engaging corresponding parts on the pistons. Each of the pistons is pulled upwardly by means of U-shaped connecting rods 61, the lower ends of which work over pins 57 fixed in the piston, helical springs being interposed between the ends of the connecting rods and the upper part of the piston. Upward movement of each piston is comparatively free, while down. ward movement is resisted. Each piston is provided towards one side with openings parallel to the axis through which pass metering rods 69, 79 whose end movement is controlled by springs 72 at the lower ends. and by the cover 33. Each piston is provided with one-way offset valve 58, connecting the underside of a piston with an intermediate recess. The metering rod 69 is formed with a slot 70 and the metering rod 79 with a shallower groove 80. Movement of the pistons 51, 52 upwards or downwards at or near the central position shown is practically free owing to the facilities for leakage provided by the slot 70 and the recess 80 in the metering pins. Upward movement of both pistons is also unrestrained over the greater part of the range in view of the facilities for downward flow of the liquid through the slots or recesses in the metering pin and the one way valves 58. As soon as either piston is moved downwardly until the slot or recess in its metering pin is covered, further leakage of liquid can only take place past the heavily spring-loaded valves 90 shown in Fig. 5. Liquid then passes through the opening 87, 96 past the valves and upwards through passages, not shown, into the body of the casing. Springs 91 of different strength may be used in the relief valves so as to obtain differential action of the apparatus.
