Title: Improvements in or relating to chassis for rail vehicles and springs therefor
IPC: B61F5/08
Filed: 1948-06-25
Abstract: 657,316. Springs; railway vehicle undercarriages. CROMPTON PARKINSON, Ltd. June 25, 1948, No. 17177. Convention date, July 3, 1947. [Classes 103(vi) and 108(iii)] A composite spring for a bolster for a rail vehicle, comprises a plurality of concentric springs, one of which is supported on a base and supports the remainder of the springs and means adapted to transmit vertical loading from a bolster to the springs which in operation act in series and resist vertical loading by compression, each of the springs being composed of a stack of rubber rings with at least one metal ring between each adjacent pair of rubber rings. In the arrangement shown, as applied to a rail chassis of the type described in Specification 642,843, a bolster 14 is supported on a platform 13, at each side of a chassis frame, by three concentrically disposed rubber springs 15, 16, 17. The springs 15 and 16 each comprise a stack of rubber rings 18 bonded in pairs on each side of metal rings 19 and between outer metal rings 20, the adjacent rings 20 being dowelled or otherwise secured together. The spring 17 comprises a stack of substantially wider rubber rings 21 separated by metal rings 22, assembled on a base plate 23 and capped by a top-piece 24 which under light load, carries the weight of the bolster 14. The spring 17 is carried in a cup 29 which is supported at its rim 30 by the spring 16, which in turn is carried by a cup 28 supported at its rim 27 by the spring 15. Deflection of the springs under increasing load on the bolster 14 is progressively limited by stop-rings 31, 32, until, for maximum deflection of the spring 15. the cups 28 and 29 bear on the platform 13. Swinging movements of the bolster are damped bv rubber blocks 35, carried by brackets 33 and 34 at either side of the bolster spring and which are in rubbing engagement with skirts 37 integral with the bolster. Excessive swinging movements are limited by flanges, which control the brackets 33 and 34 when the bolster tends to swing excessively in either direction.

Title: Hydraulic jack
IPC: B66F5/04
Filed: 1945-07-05
Abstract: 595,522. Hydraulic jacks. PAGE, H. E. July 5, 1945, No. 17209. Convention date, July 5, 1944. [Class 78(iii)] A hydraulic lifting jack comprises a body forming a horizontally disposed cylinder containing a piston operatively connected with a lifting arm which is pivotally mounted on the body, said piston forming with the cylinder a main pressure chamber to which a large area of the piston is exposed for slow high-pressure actuation of the lifting arm and an auxiliary pressure chamber to which a relatively smaller area of the piston is exposed for rapid low pressure actuation of the lifting arm, both chambers being connected by check valve controlled passages with a fluid pressure generating means whereby said check valves are normally urged by springs into seated position toward said pressure generating means, the spring urging the check valve in the passage leading to the auxiliary chamber being yieldable to less pressure than that required to unseat the valve controlling the passage leading to the main pressure chamber. In the embodiment shown, the jack comprises a body 5 forming a cylinder 6, a pump cylinder 7 and a reservoir R, and a lifting arm 11 pivotally mounted on the body at 10 and connected by a pin 39 to the connecting rod 38 of a piston 30. The cylinder 6 has a reduced diameter portion 6a and the piston a corresponding reduced portion 30a so as to form an annular space 35 constituting an auxiliary pressure chamber, the main pressure chamber 36 being formed by the inner face of the piston and the inner part of the cylinder 6. A pump piston 45 is reciprocated in the cylinder 7 by a pinion 48 on an operating lever 49 engaging its rack portion 46. A valve bore 55 in the body 5 forms chambers. 56, 57, 58 which are provided with check valves 59, 60, 61. Spring- controlled actuating members 65, 70 are provided between valves 59, 60 and 60, 61 respectively, whilst the valve 61 is urged seated by a relatively strong spring. 75 bearing against a threaded plug 76. When the piston 45 is reciprocated, on each suction stroke fluid is drawn into a pressure chamber 82 from the reservoir R through a port 80, past valve 59 and through a port 81, and on each pressure stroke this fluid is forced through the port 81, past valve 60 and through a port 84 into the-chamber 35 whereby the arm 11 is raised quickly into contact with the load. Thereafter the spring 75 is overcome by the resistance of the load and fluid is forced past the valves 60, 61 through ports 84, 85 into both chambers 35, 36 to lift the load. Pressure is released from these chambers to lower the jack by screwing inwardly by means of a handle 97, a valve operating member 95 provided with a stem 96 adapted to push the valve 59 off its seat and through the members 65, 70 unseat the valves 60, 61. The loadengaging saddle 12 is maintained horizontal by a bar 17 pivotally connected to the saddle at 18 and to a pin 14 on the body 5.

Title: Improvements in electric supply systems for loads capable of regenerative operation
IPC: H02M7/00
Filed: 1938-06-10
Abstract: 514,927. Converting. BRITISH THOMSONHOUSTON CO., Ltd., and WHITELEY, A. L. June 10, 1938, No. 17301. [Class 38 (ii)] Relates to a system in which a load capable of regeneration is supplied from a rectifier and means are provided for inserting a resistance 2 across the load during regeneration, and consists in using a discharge device T as the means for detecting when regeneration occurs and for operating the contactor 1a which inserts the resistance. To the grid of the valve is applied a bias proportional to the line voltage, opposed to a constant negative bias so that the valve becomes conductive when the line voltage rises above a predetermined value. A maintaining circuit for the coil 1 is completed through the contacts 1b, 6a and this is opened to open the contactor when the contacts 6a are opened by a time delay relay 6 under the control of a directional relay 5. The directional relay also controls the insertion of a resistance 4 by means of contactor 3a when the load drops below a given value to maintain the rectifier operating above the'transition point. In a modification a number of resistances 2 each with a control discharge device T and operating in succession may be used. Specification 502,568 is referred to.

Title: Improvements in method for tufting pile fabrics
Inventor: BALLARD HYDE WHITCOMB
IPC: D05C15/22
Filed: 1963-05-03
Abstract: 1,011,371. Tufting machines. JAMES LEES AND SONS CO. May 3, 1963, No. 17599/63. Heading D1G. In making tufted fabrics, the tension in the pile yarns is varied in accordance with a predetermined pattern, and the pile loops are released in accordance with said varying tension without removing yarn from previously formed pile loops. In Fig. 1 needles 21 carried by a needle bar 20 are supplied with yarns Y. Groups of yarns are passed over friction-faced rollers 27, 30 the speeds of which are varied to produce variations of tension in the respective groups. Individual yarns pass through aligned apertures 36, 38 in respective receptacles 35, and through respective apertures 37 in plungers 32 vertically slidable in the receptacles. A plunger normally rests on a stop screw 34, when aperture 37 is aligned with apertures 36, 38. On energization of a solenoid 40, plunger 32 is raised to engage a stop screw 33, thereby tensioning the yarn. The looper hooks 55, which co-operate with a loop-stripping comb 62, are vertically-slidable in the looper bar 58, and are biased to their lowered positions by respective springs 59. Increase of yarn tension thereby strives to shorten the pile loops produced. A presser foot 50, having an elastic face 51, is carried by a bar 52 slidable relatively to the needle bar and biased downwardly by a spring 53 to engage face 51 with the base of the previously formed loop to prevent withdrawal of yarn therefrom, the presser foot rising with the needle bar to permit work feeding. In Fig. 11 the looper hook is in the form of a resilient wire 65 which is bent upon itself to form a loop-taking beak 69, and is rigid with a blade 66 which is clamped to the looper bar. In a modification the return hand of the resilient wire is omitted. In a further modification a resilient wire 13 has a rigid loop-taking beak 72.

Filed: 1975-04-29
Abstract: 1507705 Multicoloured soaps HENKEL & CIE GmbH 29 April 1975 [28 June 1974] 17672/75 Heading C5D [Also in Division B5] A soap bar comprising a pattern of different coloured soaps is made by screw extruding a soap column having veins of a different colour extending parallel to the longitudinal axis of the column, cutting the column into sections between parallel cut surfaces 5, 6, Fig. 2, which are at an angle α, of 75 degrees to 15 degrees to the column axis, and then stamping each section into tablets between moulds 8, 9, at a direction of stamping which is at an angle #, of 90 degrees to 30 degrees to the cut surfaces 5, 6. The process minimises cracking of the tablet, in use, which would otherwise come from the greater distortion of the veins e.g. by cutting at 90 degrees and stamping along the column axis. The extruded column comprises veins branching out generally radially from the column axis, and the process produces a pattern in the tablet 10, Fig. 3, in which the axis 12 of the pattern extends through the tablet at an angle to the axis 11 of the tablet. Stripes 17, Fig. 7, may be produced at one edge of the tablet.
