Patent GB-2023221-A (GB)
Title: Spring door closers
IPC: E05F1/10
Filed: 1979-06-28
Abstract: A door closer comprising an arm which in use engages a door to urge it into its closed position. The arm is rotatable about an axis parallel to that of the door and urges it closed by spring means capable of exerting a greater torque on the arm when the door is at or near its closed position than when it is in an open position, the torque exerted being a function of the rotational position of the arm. In the embodiment shown the door closer comprises a bevel gear 1 secured to the arm which engages a rack 4 movable against the bias of the spring means. One end region 6 of the rack has teeth engageable with a portion of the bevel gear of a first, greater diameter so that the spring exerts the greater torque. The other end regions 5 of the rack has teeth engageable with a portion of the bevel gear of a second smaller diameter. In another embodiment a spiral cam and a cam follower is used, the cam follower being movable against the bias of the spring means to a position where a wider portion of the spiral cam engages the cam follower. <IMAGE>

Title: Electronic keyboard musical instruments
IPC: G10H1/20
Filed: 1980-05-01
Abstract: The selective retuning of one or more white notes of the keyboard of an instrument in order to allow glissando or similar effects to be achieved in any key by stroking across the white notes. One of three outputs from a master oscillator (M) representing the fundamental note, a semitone sharp, and a semitone flat is routed to a bus output line (L) via one of the NAND gates (G6, G7, G8). A three way switch (SW1), AND gates (G1, G2, G3), and inverters (G4, G5), selects which of the three NAND gates is enabled according to its position. There are six additional similar systems so that by setting seven switches in their appropriate positions glissando can be achieved in any desired key or mode.

Filed: 1981-07-08
Abstract: In conventional cold working of a fastener hole in materials to be joined (15, 16) by drawing an oversized mandrel (19) through the hole, the unworked hole edge can act later as a centre for fatigue damage in loaded structures. Therefore, a die (12) having a raised coining annulus (14) is provided to deformably contact the hole edge when it is urged into the hole, as for example in reaction to drawing the mandrel (19). Non- deforming contact between a material surface (11) and a die surface (18) limits the extent of deformation. <IMAGE>

Title: Producing filler material, particularly for cigarette filters
IPC: A24C5/39
Filed: 1981-07-30
Abstract: Filler material, particularly for cigarette filters, is produced by feeding a stream (10) of substantially continuous fibres of filter material onto a pin roller (16) which is driven at a speed such that the fibres are broken by the pins (15) into irregular lengths and are projected from the roller in random orientations. The broken fibres may be collected as a stream for delivery to a rod-making unit (21) by showering onto a conveyor band (20), by continuously rolling the fibres between cooperating rollers, or pneumatically. More than one stream (10) could be supplied to the pin roller (16), so that the broken fibres can comprise a mixture of fibres of different filter materials. The broken fibres may be received on a substantially continuous carrier stream, comprising similar or different filtering material, before the fibres and carrier streams are formed into filter rod. <IMAGE>
