Patent GB-2114466-A (GB)
Title: Manufacture of articles of reinforced acrylic sheet material
Inventor: GRIFFITHS RONALD
IPC: C08J5/12
Filed: 1981-12-12
Abstract: In a process for manufacturing an article such as a bathtub fabricated from moulded acrylic sheet a shaped shell of the acrylic sheet is reinforced by a layer of glass fibre reinforcement applied using a polyester resin composition incorporating a blowing agent and hollow glass microspheres dispersed therein. The hollow microspheres promote and enhance bonding to the acrylic sheet substrate in the presence of the blowing agent which in turn promotes encapsulation of the reinforcing glass fibres so that no separate "rolling out" operation is needed after application. The hollow microspheres also reduce the density of the reinforced resin material.

Patent GB-2139039-A (GB)
Title: Electronically detecting the presence of film dirt
Inventor: STOREY RICHARD
IPC: H04N5/253
Filed: 1984-03-09
Abstract: Dirt on a film frame is detected from a video signal obtained from the film by a telecine by comparison of the video signal derived from successive film frames. Signals A, B and C from three frames are applied to subtractors (12,14) to generate the differences A - B and C - B which are rectified (16,18) and applied to threshold circuits (20,22). A sign comparator (26) detects whether B lies between A and C. If B is not between A and C and differs from both of them by more than an amount d, then the presence of a dirt blemish is indicated. The value of d may be adaptively dependent upon signal content. Two motion detectors 52,54 each detect in a different manner the presence of movement in the scene content, and their outputs are combined in a mixer 70. The mix itself can be dependent upon the outputs of the motion detectors. Also, an unsteadiness detector 110 detects unsteadiness between film frames and modulates a signal representing the high frequency detail content of the signal to vary the value of d. <IMAGE>
