Patent GB-2008267-A (GB)
Title: Method of Image Reproduction and Materials Therefor
IPC: G03F7/12
Filed: 1978-10-30
Abstract: A high resolution image is accurately but readily reproduced by placement of a master, such as a positive photographic film, in direct contact with a wet, high solids content, light curable material distributed on a screen or solid substrate. The light curable material includes a sensitizer, may include a reactive diluent, has only a minor proportion of evaporable solvent, if any, is preferably free of acrylates and of low toxicity, and has a viscosity sufficient to maintain a fixed spatial relationship between the master and substrate. The light material may further advantageously incorporate a dimensional stabilizer such as a distributed particulate, an opacifier, or both. This combined system is then exposed through the master with a suitable light source and is rapidly cured in a pattern corresponding to the image of the master. The master is then stripped off without damage and the uncured material washed away, and the reproduced image may be post cured if desired. The result is a high resolution, durable image that can be used for printing purposes, printed circuits, and other quality reproductions, but nonetheless is obtained within a few minutes and without the use of complex procedures and equipment. The presence of a dimensional stabilizer in the light curable material is shown to have beneficial effects on the physical characteristics of the reproduced image, the fidelity of the reproduction to the original, and on the tolerance of the light curable material to light exposure variations.

Title: Detecting knocking in an engine
IPC: G01L23/22
Filed: 1978-11-22
Abstract: Vibration produced in an internal combustion engine during normal operation is detected at 1, and a corresponding electrical signal is produced and stored at 9, 10 and 11. Meanwhile, the engine is continuously monitored, and the onset of, and vibration of the engine during, knocking are detected and a corresponding electrical signal is produced. Then the signal corresponding to normal operation of the engine is instantaneously substracted at 12 from the signal corresponding to knocking in the engine to produce a resultant signal in which contributions due to background engine noise during knocking are suppressed. The signal stored is produced from the output signal of the detector 1 by utilizing a voltage controlled oscillator 9 which produces an output signal having a frequency at the detector output frequency and a storage device 10 which detects the peak of the detector output signal during normal operation, the outputs of the oscillator 9 and the device 10 being combined at 11 to provide a signal which is applied to the subtractor 12. <IMAGE>
Patent GB-2011277-A (GB)
Title: Method of strengthening the shells of echinoderms
IPC: B44C5/06
Filed: 1979-01-19
Abstract: The method comprises applying to the cleaned shells (for example, sea urchin shells) at an ambient temperature of not less than 60 DEG F, a colourless vinyl polymer-based aqueous emulsion coating composition having a specific gravity of from 1.05 to 1.20 at the application temperature, and allowing the composition to dry. The vinyl polymer is preferably a polyvinyl ester, such as polyvinyl acetate. The method enables the shells to be adequately strengthened using a relatively inexpensive coating composition which is easy to apply without causing pollution, whereby the entire surface of the shell can be coated without blocking holes in the shells. The coating does not detract from the appearance of the shells and sometimes enhances it.

Title: Radiographic apparatus
IPC: A61B6/00
Filed: 1979-02-13
Abstract: A combined X-ray fluoroscopy and radiography device includes an X-ray image-intensifier 4, video apparatus 24, 26, means for disposing a photographic film 27, dispensed from feed-spool chamber 28 to take-up chamber 29, in the optical path directly adjacent the intensifier output screen 14, and a ring 30 urging the film against the intensifier exit window during an exposure. The exit window comprises a fibre optic plate 6. To prevent damage, a replaceable fibre optic plate 15 is applied thereto. Exposure is sensed optically via the film, and exposure or video input intensity is adjusted by controlling intensifier gain, e.g. by varying the intensifier accelerating voltage in conjunction with a metal film covering the fluorescent screen 14, whose electron permeability varies by 1:10 for a 1:2 accelerating voltage change. Auxiliary optical means project identification symbols onto the film 27 and/or camera 24. The film image can be secured in a window in an indexed card of an addressable indexed-card information storage and retrieval system for addressable retrieval and automatic projection. <IMAGE>

Title: Sampled or digitized color moviola in a record and replay system
IPC: H04N9/808
Filed: 1981-02-27
Abstract: Moviola color picture quality is improved for a record and/or replay system wherein video information sampled at a predetermined multiple of the color subcarrier frequency is recorded with each frame or field being disposed on a set of multiple tracks and with only a portion of the recorded information being intended for replay to reconstruct the color moviola signal. Only pixel groups (1-4, 5-8, 9-12, etc) relating to entire color subcarrier cycles are recorded on the tracks (1, 2 or 3) so that a video signal having proper color information can be readily reconstructed therefrom during the moviola mode. In one embodiment, sequential color subcarrier cycle pixel groups (1-4, 5-8, 9-12) are recorded on separate tracks (1, 2, 3) and those (1-4, 13-16, etc) on a single track (1) are replayed during the moviola mode with the pixel groups on the single track repeated in sequence when reconstructing the moviola picture, thereby supplying instantaneously coherent information. <IMAGE>
