Title: Improvements in or relating to fluid pressure remote control systems
Inventor: CLENCH EDWARD CLAUDE SHAKESPEA
IPC: F15B15/26
Filed: 1960-06-01
Abstract: 898,260. Pneumatic single-stroke apparatus. AUTOMATIC PRODUCTS CO. Ltd. March 23, 1961 [June 1, 1960], No. 19417/60. Class 8(2). [Also in Group XXIX] The piston 12 of the motor unit of a fluid pressure remote control system is locked in the cylinder 11 against movement under an external load by means of rolling members such as balls 38, which provide a locking pressure when forced between axially convergent surfaces 21, 37 on the piston and on an axially split sleeve 34 which surrounds the piston and frictionally engages the cylinder wall. The rolling members during fluid operation of the unit are displaced by sealing and rigid rings 26, 30 which are acted on by the fluid pressure moving the piston. The members are maintained by a spring 39 into light engagement with the surfaces 21, 37 when the piston is not subjected to external loading and to fluid pressure. As shown, the locking mechanism is duplicated in order to lock the piston against movement in both directions. The piston consists of sleeves 19, 22 and rings 20, 23 clamped together on a rod 14 by a nut 17. The ring 20 is formed with an external frusto-conical surface. The sleeve 34 is split at one end to form fingers 36 and is -provided at its other end with a flange 35 against which the spring 39 bears. If, for example, an external load is applied to move the piston to the right, the left hand sleeve 34 due to its frictional engagement with the cylinder wall will be left behind as the piston moves and will cause the balls 38 on the left to move radially outward on the frusto-conical surface of the ring 20 and wedge the fingers 36 of the sleeve 34 against the cylinder wall to lock the piston. If the unit is then to be operated with the piston moving to the right, fluid pressure acting on the piston will also act on the left hand rings 26, 30 and cause them to move the balls 38 out of engagement with the surfaces 21, 37 so as to unlock the piston.

Title: Improvements in or relating to wallboard joints
IPC: E04F13/04
Filed: 1934-07-02
Abstract: 439,304. Walls; wallboard joints. JACKSON, L. MELLERSH-, 28, Southampton Buildings, Chancery Lane, London.-(Gypsum, Lime, & Alabastine, Canada, Ltd.; Paris, Ontario, Canada) July 2, 1934, No. 19475. [Class 20 (iv)] A joint for the end or side marginal edges of wallboards comprises means whereby the marginal edges of adjacent boards are depressed when nailed to a stud 5, so as to form a space 2 for the reception of a joint filler which is arranged to merge evenly with the surface of the boards. The invention also consists of a joint comprising the marginal edges of two adjoining boards 1, as shown in Fig. 2, a stud 5 to which the said edges are nailed, a block 8 on each side of the stud 5, and means on each of the blocks 8 to provide a bearing surface for a board, such bearing surface being spaced from the stud. The bearing surface on the block 8 may be formed by a fibrous or other shim 6<a> so as to provide a depression 2 at a vertical joint. At horizontal joints, the space 2 may be provided by means of shims 6, Fig. 3, secured to the studs 5 and terminating a short distance from the side edges of the boards. The space 2 may also be provided by cutting a slot 7, Fig. 4, in the ends of the boards to permit the upper part of the margin of each board to be depressed when nailed to the stud. Boards, the end edges of which are jointed as described above, may have the side joints formed by the use of wallboards having bevelled edges, either face of such wallboards being secured to the studs. The marginal edges of the boards are treated with a waterproofing agent. The joint filler, which may consist of a fine-grained motor, is preferably applied so as to provide a slightly depressed central portion at the joint. Where the boards are applied to both faces of studding so as to form a hollow wall, the inturned edges of the boards may be effective in supporting a loose dry insulating material in the wall. The wallboards are of the type comprising a gypsum core and paper covering sheets.

Title: Improvements in or relating to automatic flash-butt welding
IPC: B23K11/04
Filed: 1958-06-19
Abstract: 884,674. Welding by pressure. ALLMANNA SVENSKA ELEKTRISKA A.B. June 19, 1958 [June 20, 1957], No. 19593/58. Class 83 (4). In flash-butt welding in which one workpiece is moved into and out of contact with the other workpiece during preheating, the rate of movement of the workpiece during flashing is initially reduced. Simultaneously with the reduction of speed, which occurs after a predetermined preheating period, the welding voltage may be increased to facilitate flashing. After a predetermined length of the workpieces has been flashed away the speed is increased to produce the weld. Tubes welded in this way may have a stream of gas such as argon passed through them during welding. A motor 16, driving the movable work-holder, is supplied by a generator 19. When preheating is started contacts 3<SP>1</SP>, 3<SP>11</SP> connect the field-winding 2 of the generator across a D.C. supply in series with a valve 4. When the workpieces contact, 11<SP>1</SP>, 11<SP>11</SP> close and 3<SP>1</SP>, 3<SP>11</SP> open to reverse the connection of the field 2 so that the workpieces part. The speed of reciprocation is determined by resistances 10, 12. After a predetermined time contact 13 closes and when next 3<SP>1</SP>, 3<SP>11</SP>, 3<SP>111</SP> close, the biasing voltage from a source 9 is short-circuited and a condenser 7 in the circuit of the control grid 6 of the valve 4 is charged so that the speed of the motor 16 is reduced and then gradually increased as flashing takes place. When the predetermined length of the workpiece has been flashed, 15<SP>1</SP>, 15<SP>11</SP> close to accelerate the motor 16 for the final upsetting action. In a modification, Fig. 2, the reduction in speed followed by the acceleration is obtained after the preheating time has elapsed by increasing the resistance in the generator field circuit and then via contact 31 connecting the armature circuit to the field circuit 24 of the generator 22. The final increased upsetting speed is derived by shorting the resistance 32. In a further modification a three-phase asynchronous motor having two sets of windings with different numbers of poles is used.
