Abstract: 1367497 Colour television MAGNAVOX CO 11 Nov 1971 [13 Nov 1970] 52482/71 Heading H4F For use in a colour television system of the type described in Specification 1,322,041 a black and white photographic film has recorded thereon superimposed separably distinguishable images of three different colour components of a scene, each image being spatially modulated by a pattern of parallel lines inclined to a predetermined direction (e.g. the horizontal scanning direction of a television pick-up tube), the three patterns differing from each other by their direction of inclination, but the line spacings of all three patterns in the predetermined direction being the same (i.e. the resulting colour carrier signals have the same frequency but different phases). Specifically striped red, blue and green filters are used sequentially or simultaneously for recording a colour image in monochrome on the film, the red and blue striped filters being inclined at equal and opposite angles to the horizontal scanning direction so that the phase of the resulting carriers effectively rotate through 120 degrees in opposite directions on successive scan lines, and the green striped filter being orthogonal or inclined to the horizontal scanning dirction so that the resulting carrier is in phase or out of phase by 180 degrees in successive horizontal scan lines.

Title: Heat-treating method
IPC: C22F1/00
Filed: 1972-11-17
Abstract: 1490181 Heat recoverable alloys: heat treatment RAYCHEM Ltd 15 Feb 1974 [17 Nov 1972] 53243/72 Heading C7A An article is formed from a heat-recoverable alloy which has been treated to expand its M s -A s  hysteresis loop so that the As temperature is raised above its initial value. The treatment may consist of slowly heating the alloy e.g. at < 1‹C/ min. from temperature below Mf to a temperature above the initial As and to which it is desired to raise A s ; the alloy is then transformed to the martensitic state and deformed after which it has heat recoverability. The austenitic state is defined as the high-temperature-stable form which is capable of undergoing a shear transformation to martensite on cooling. Before carrying out the martensite transformation it may be necessary to heat the alloy to a temperature at which it is completely austenitic (e.g. in the case of copper alloys 700- 950 degrees to ensure formation of a completely beta structure) followed by quenching (e.g. to 20 C). Alloys particularly disclosed include Cu - (1À5- 3% Si) - (29-345% Zn), Cu - (0À5-4À5% Al) - (25À7-37À3% Zn), and Cu-10À5% Al-9% Mn. As exemplified alloys in the austenitic state are cooled to -40‹C to -79‹C, slowly heated to 40-75‹C, cooled to sub-zero temperature and deformed to produce heat recoverability.

The demountable unit may be in the form of a welded high wall container as shown in Fig. 1, or a flat stillage framework, Fig. 7. In either case the base thereof has a mounting piece 46 at its front end and a pair of pivot stubs 29 at the rear. In order to mount the unit on the vehicle the latter is reversed so that the rear edge of the vehicle platform abuts retractable legs (not shown) on the unit which pivot upwardly. Wheels 59, 60, 61, 62 mounted on the unit roll on the surface and sides 24 of the platform 12 and the reversing movement is terminated when mounting piece 46 enters between box section mountings 42, 43 of the tipping arrangement. Pins 45 Fig. 5, are inserted through the mountings for securing the front end of the unit to the jack 50. In this position pivot stubs 29 at the rear of the unit drop into slots 25 provided in plates 24 of the platform 12 and are secured by hooks 30. In order to pivot the unit, screws 48 are slackened and swung away from solid bar 47 and hydraulic jack 50 operated via feed pipe 52.

Aluminium or magnesium powder may be included as an additional fuel. Agents to control the emulsion droplet size, emulsion stabilizers, thickening agents for the aqueous or aliphatic nitrate phase, and cross-linking agents may also be added; many specific examples of these additives are given.

Preferably the coated metal core is passed through an oven before being engaged by the tensioning device. After drying the core is preferably passed through a further nip to consolidate the coatings. The dough-like composition may contain a solvent system including a volatile solvent for the elastomer and an non- solvent liquid. Suitable liquids are toluene and water respectively and preferably the ratio of toluene to water is greater than 4 to 1 and less than 10 to 1 by volume. The metal core may be a wire gauze or a perforated sheet or a plain or embossed sheet metal. Preferably the core is coated with an adhesive before the composition is applied. The adhesive may contain a curable adhesive material in solution in a solvent and is applied as a film of thickness 5 microns. The adhesive is preferably partly soluble in the solvent system of the dough-like composition. A suitable adhesive is nitrile rubber and a phenolic resin in the solution of a polar solvent such as ethyl acetate. The fibrereinforced coating may be of unequal thicknesses on the two sides of the metal core.

Abstract: 1.174,415. Loud speakers. A. RIZO-PATRON, REMY. 20 Dec., 1966 [3 Jan., 1966], No. 56898/66. Heading H4J. A speaker system has two spaced, coaxially mounted cone-type low-frequency speakers of the type producing front and rear waves of acoustic energy connected such that their diaphragms move in the same direction at any given instant. An open baffle of sound opaque material is joined, acoustically tight, to each of the speakers. The speakers are enclosed in cloth. A speaker 42 (Fig. 1) has its magnet structure secured by thumb screws 43 in a socket 44 at the top of a pedestal 45. A lead shell 46 with an aperture 47 for the speaker 42 is lined with sound-absorbing material 48. A similar lead shell 49, lined with sound-absorbing material 55 and having a central aperture 56, is secured between a spider 50 and the mounting flange of a smaller speaker 51. Acoustic cloth 59 is supported by a wire frame 60 which rests on the magnet of speaker 51 and the upper edge of the shell 49. The shells 46, 49 are substantially cylindrical. Alternatively, the shells may be polygonal (Figs. 4 to 6, not shown), e.g. rectangular, and have corrugations and irregularities. The side walls may curve gently and the corners follow an exponential path. In order to supplement the upper frequency range, two smaller speakers (73, 74) are mounted coaxially in much the same way as the larger speakers except that they are not supplied with baffles. The smaller speakers (73, 74) are supported between wire frames (76, 77) above the larger speakers, and acoustic cloth (78) surrounds the frame (77). The smaller speakers (73, 74) are energized in phase with one of the larger speakers, filter or cross-over networks being incorporated where required. Alternatively, (Fig. 7, not shown), baffles (80, 81) are given a different profile so as to be accommodated in a tapering frame (82) and acoustic cloth enclosure (83). For ceiling mounting (Fig. 8), the structure of Fig. 7 is used, inverted and truncated. A frame (90) supports high frequency speakers (79) below the larger speakers. In a further arrangement, identical speakers (92, 93), Fig. 9 (not shown), with bowl-like baffles (94, 95) are joined by studs (12). The baffles (94, 95) are identical, being formed from sheet lead lined with sound-absorbing material (98). A cylindrical acoustic cloth (96) and a pedestal provide a construction similar to a table lamp. Instead of lead, the baffles may be of glass wool, felt, cork acoustic " Celotex" (Trade Mark) expanded polystyrene or foam rubber.
