Title: Information recording system
IPC: G01D5/245
Filed: 1981-07-21
Abstract: In Figure 2, the position of a reading head 13 relative to an information track 10 is obtained using counting (at 19) of sections of the track, each section being a light zone and a dark zone. Absolute-position groups of bits (starting and ending with sync signals) are recorded on the track also, one bit per section, the bit value being given by whether the light or the dark zone is the longer, these bits being received in a shift register 23. The proportions of the zones could be selectively 1:4, 1:2 or 1:1. A separate track can be used for the bits. <IMAGE>

Title: Dubbing translating of soundtracks on films
Inventor: ROCK KENNETH EDWARD
IPC: G11B27/028
Filed: 1982-07-07
Abstract: A portion of a speech soundtrack 11 to be translated is displayed on a video screen of a playback unit 1 in synchronisation with lip movements of actors speaking the words with reference to a graphical sound representation histogram 9 produced by a sound conversion section 5 of a computing unit 2.

Title: Method of hot-forming metals prone to crack during rolling
Inventor: CHIA E HENRY
IPC: B21B1/46
Filed: 1983-02-04
Abstract: A method of continuously casting a molten ferrous alloy in a casting means (12) to obtain a solidified cast bar (20) at a hot-forming temperature, passing the cast bar (20) at a hot-forming temperature from the casting means (12) to a hot-forming means (10), and hot forming the cast bar into a wrought product by a two-stagereduction of its cross-sectional area while it is still at a hot-forming temperature, including, in the first stage, the step of forming a substantially uniform fine grained, equiaxed or cell structure in the outer surface layers of the cast bar by a selected small amount of deformation of the cast bar in its as-cast condition prior to the second stage in which substantial reduction of its cross-sectional area forms the wrought product. The substantially uniform subgrain structure formed on the cast bar during the first stage of deformation produces a bar that has increased ductility compared to bar produced by the prior art processes and permits substantial reduction of the cross-sectional area of the cast bar during the second stage of deformation without the cast bar cracking, even when the cast bar has a relatively high percentage of alloying elements present.

Patent GB-2141529-A (GB)
Title: Control system
Inventor: SEXTON RONALD DAVID
IPC: F42C15/40
Filed: 1984-06-15
Abstract: A 'safety interlock' type of control system, for example a missile arming chain, in which a series chain of switches 1-4 makes available a system output response when each of a series of input conditions sensed at 8-11 are met, includes also a bypass element 7 responsive to some further input condition sensed at 12 to bypass one or some of the switches and sensors. The further input condition (e.g. passage of a predetermined saft time period) indicates certain achievement of the conditions whose associated sensors are bypassed, so that if one of the switches remains off it is due to a fault rather than actual non- achievement of the sensed condition. The use of the bypass feature may render the overall system more reliable. <IMAGE>

Title: Improvements to thin film mirrors
Inventor: WILLIAMSON DAVID THEODORE NELS
IPC: G02B26/06
Filed: 1985-10-23
Abstract: Thin film mirrors formed by stretching a diaphragm of reflecting material over a usually circular frame and adjusting the curvature by lowering the air pressure on one side of the diaphragm suffer from defects caused by changes in barometric pressure, wind forces and lack of uniformity of the membrane material. This invention enables correction of these defects by subjecting a diaphragm to localised electrostatic forces which in the limit can replace air pressure and/or provide a dynamically changeable surface curvature. The electrostatic forces may be applied by a series of concentric ring electrodes. The segments and/or the diaphragm may be divided into segments such that independent potential feeds may be applied to different areas of the diaphragm. <IMAGE>
