Patent GB-2033507-A (GB)
Title: A friction drive assembly
IPC: F16H61/662
Filed: 1978-10-17
Abstract: An input shaft (1) drives an output shaft (18) through a roller (7) which is displaceable along its rotational axis (8) while maintaining driving engagement with drive faces (6 and 14) of the shafts (1 and 18) respectively to vary the transmission ratio. The roller (7) is controlled in its displacement by a piston and cylinder device (10) to which fluid pressure is directed under control of a spool valve (22) actuated by a centrifugal governor (34) so as to maintain a substantially constant speed of the output shaft 18. In alternative embodiments the piston and cylinder device (10) is single acting and with such a device the spool valve (22) can be omitted and fluid pressure directed to the piston chamber of the single acting device from a pump driven by the output shaft (18). <IMAGE>

Patent GB-2056721-A (GB)
Title: Stylus position sensing apparatus for a disc record player
IPC: G11B21/04
Filed: 1980-07-07
Abstract: In a video disc player, a stylus arm (24), carrying a track following stylus (20) at one end thereof, has its other end secured to a carriage by a compliant member (30). The carriage is translated along a path disposed radially of the disc record during playback. Pickup circuits (52) are employed for sensing the variations in a signal representative capacitance formed between an electrode incorporated in the pickup stylus and conductive material disposed in the record to recover pre- recorded information from a spiral track disposed on the record. A stylus position indicative capacitance (94, 98) established between a first electrode secured to the stylus arm and coupled to the pickup circuits and a second electrode mounted to the carriage in the vicinity of the first electrode, is provided. In an embodiment, the stylus position representative capacitance is formed between a signal coupling flylead (38) of the stylus and the second electrode which is mounted on a cartridge (32) housing the stylus in the carriage. Circuitry (108-112) is provided for sensing signals appearing at the output of the pickup circuits to generate a signal indicative of the position of the pickup stylus relative to the arm cage. The rate of translation of the carriage is varied (46) in response to the stylus position indicative signal to maintain a desired relationship between the pickup stylus and the arm cage. <IMAGE>

Patent GB-2109624-A (GB)
Title: Channel plate electron multipliers
Inventor: BUHLMANN FREDERICK THEODORE
IPC: H01J43/22
Filed: 1981-09-30
Abstract: The dynode plates of a discrete dynode channel electron multiplier should be bonded together in a rigid stack, electrically insulated from one another, at a controlled spacing. To provide barrel-shaped holes in the dynodes for correct electron-optical operation, half dynode pairs 2, 3 are bonded together by the insulating spacer to form a sub-assembly in which one half dynode 3 is coated with the secondary emitter 10 and forms half of one barrel-shaped hole and the other half dynode 2 provides the field controlling part of the following barrel-shaped hole. Glass can be used as the bonding and insulating spacer. In the invention a high melting point glass is fused to the field half-dynode in a layer 13 of controlled thickness and a low melting point glass layer 12 of smaller thickness (as shown) is fused to the emitting half-dynode. The sub- assembly is then formed by heating both half-dynodes to the lower temperature and pressing the glass layers together. Bonding is achieved at a separator thickness largely controlled by the high melting point glass layer, but at a bonding temperature which is low enough to avoid cosmetic disfigurement of the emitting surface 11 and consequent non-uniformity of emission from all channels. In a modification the glass layers on opposed half-dynodes are not in register, in which case the two glass layers may be of equal thickness. <IMAGE>

Title: Cavity wall tie for existing walls
Inventor: ADAM IAN ROSS
IPC: E04G23/02
Filed: 1982-03-23
Abstract: Leaves 2,3 of a cavity wall are tied by stainless steel tie rod 1 inserted into bores 5,4 in the leaves. Tie rod 1 is secured in the innermost (blind) bore 4 by sleeve 11, which radially expands upon axial compression, on a threaded end of the tie rod between a stop member 8 fast with the rod and a threaded nut 15. Friction rings 12,14 provide that there is a higher frictional connection between the sleeve and the nut 15 than the sleeve and the stop member 8 at least during installation of the tie rod. To secure the rod (1) in the bore (4), the sleeve is pre-expanded, before insertion, so that frictional engagement of the sleeve with the bore is provided by screwing the nut towards the stop member. After insertion, further expansion of the sleeve 11 is obtained by rotating the rod, e.g. by tool 22,23, since nut 15 is frictionally connected to sleeve 11, which is itself prevented from rotation by frictional engagement with the bore. <IMAGE>

Title: Winding partially cut strip with cutting line aligned in wound coil
Inventor: LAWSON KENNETH THOMAS
IPC: B23D19/06
Filed: 1983-02-08
Abstract: Strip with partially severed scrap edge portions (16) still frangibly attached thereto, is wound on to a coil (22) so that the cut edges of the strip are aligned. The strip (10) passes past trimming knives (11) which partially sever the edge portion (16) and sensors (14 and 15) measure the lateral position (T) of the knife and the lateral position (E) of the uncut edge of the edge portion (16) adjacent to the knife position (A). The scrap width (T-E) is then recorded. As the strip (10) is about to be wound on to the coil (22) at position (B) the lateral position (R) of uncut edge of scrap portion (16) is sensed by a sensor (20). The scrap width is then determined by reference to the recorded scrap width and the strip travel between points (A) and (B) which is determined from a tachometer (17) attached to a roll (18) over which the strip passes. The actual position of the cut edge of the strip at position (B) is determined and the axial position of the coil (22) adjusted so that the cut edge of the strip on the coil is aligned. The frangible edge is subsequently removed to leave a straight-sided coil. <IMAGE>
