Title: Trim strip
Inventor: BRUCE AIDAN SIMON
IPC: E04F19/06
Filed: 1990-04-19
Abstract: A tile edging trim strip comprises a body (1) having an anchorage portion (2) and an integral edge portion (3) which projects from the anchorage portion and has an abutment part (4) remote from the anchorage portion to abut against the edge of a tile, and a platform (6) removably attached to the anchorage portion (2) which projects towards the abutment part (4).

Title: An apparatus for, and a method of, cutting a blank
Inventor: PORUCZNIK PAUL
IPC: B26F1/44
Filed: 1990-06-20
Abstract: When a blank is cut from metal sheet which suffers from crystallographic anisotropy, there is a tendency for ears to be formed during subsequent forming operations, such as drawing or pressing. In order to compensate for this tendency, there may be used a metal blank which is not completely round, but has lobes at positions to cancel at least some of the valleys between the ears. There is described a punch (110) and die (111) which may be used to form such a lobed blank (112). The punch (110) has four circumferentially extending lobe-forming sections (124). Each lobe-forming section is constructed by forming a stepped recess in the cutting edge of the punch (110). In each lobe-forming section, the depth of the recess varies from a maximum at the middle of the section to zero at the ends. The die (111) is conventional.

Title: Circuit for generating a signal coupled to a reference signal
Inventor: WISCHERMANN GERHARD
IPC: H04N5/12
Filed: 1991-02-05
Abstract: A circuit for generating a signal S coupled to a reference signal H1 (eg a video line sync-signal) includes a controllable digital oscillator 1' to which are supplied a clock signal T and a digital control signal, the control signal defining the frequency ratio between the generated signal S and the clock signal T, and a counter 4 which is interrogated to obtain the control signal. A digital signal is derived which during each period of the signal S successively assumes a plurality of different values. The digital signal is supplied to the control inputs of a controllable delay means 16, 18, which delays the reference signal H1 by a number of fractions of the period of the reference signal determined by the digital signal. The digital signal and the counter 4 value are interrogated by the delayed reference signal, with the interrogated value of the digital signal forming at least one additional binary place for the count value. The circuit provides improved phase control; it may be used in digital video technology. <IMAGE>
