Patent GB-2342533-A (GB)
Title: Pulsed interference canceller
Inventor: SUMMERS ALLAN STEPHEN
IPC: H04B1/12
Filed: 1986-06-19
Abstract: An interference canceller of the kind which serves to suppress a dominant interfering signal in the presence of smaller wanted signals is disabled in the absence of the dominant interfering signal because wanted signals tend to become dominant in these circumstances and to be themselves suppressed. Main and auxiliary receiver channels are fed from separate receiving aerials 1, 2 and a feedback signal comprising interference and wanted signals is fed from the auxiliary channel to the main channel via a vector modulator 34 responsive to control signals derived from respective channels via a correlator 16 for controlling the phase and amplitude of the feedback signals so that the dominant interfering signal is thereby suppressed. The invention provides switch means 30, 31 for inhibiting operation of the canceller when an interfering signal is absent.

Title: Knitting machine roller with card clothing
Inventor: LEINS EBERHARD
IPC: D04B9/14
Filed: 1987-12-17
Abstract: The roller 15 has a card clothing including a substrate 23 for the attachment of card wires 32 and an intermediate layer 24 to resiliently support the wires 32. Outer end sections 38 of the wires 32 are inclined in the direction of travel V relative to central sections 39 at a bend 36. Whereas in a conventional card clothing wires 25 have a central section 29 which extends in a straight line through the layer 24 to the pivot point 26 formed by the attachment of the wire to the substrate 23, the improved card clothing has the wires 32 shaped by a bend at 37 so that the pivot point 33 is displaced from an imaginary extension, of the central section 39 towards an inward direction of the roller 15. This has the effect of reducing the change in effective diameter as the card wires swing about the pivot points and of reducing the turning moment of the forces acting on the outer ends of the card wires. An additional layer between surface 22 and layer 23 may be provided. <IMAGE>

Patent GB-2218968-A (GB)
Title: Pencilbox
Inventor: WARWICKER CLIVE WALTER
IPC: A63J21/00
Filed: 1988-05-27
Abstract: A pencil box 1 has an outer casing 2, 3 and an inner drawer 6 which can be pulled out of the casing. Inner tray 7 moves with the drawer by its general frictional contact therewith. A "magic" trick can be performed by holding back the tray 7 so that drawer 6 is movable relative thereto while being pulled out of casing 2, 3. Pencils and the like can remain stored away in the casing on inner tray 7, as drawer 6 is pulled out of the casing, giving the illusion of disappearance of the pencils. The tray 7 is held back by squeezing on the lid 3 of casing 2, 3 adjacent to end wall 5 to flex a free edge of the lid downwardly relative to the upper edge of said end wall, thus projection p vertically overlaps the upper end of wall 7b of the tray 7 to prevent the tray from being slid out of the casing during said flexing. <IMAGE>
