Title: Improvements in or relating to colour television receivers
Inventor: BRABHAM HUGH BASIL SCHOFIELD
IPC: H04N9/64
Filed: 1956-02-10
Abstract: 813,482. Television. GENERAL ELECTRIC CO. Ltd. Feb. 6, 1957 [Feb. 10, 1956], No. 4308/56. Class 40 (3). In a colour television receiver for signals of the N.T.S.C. type a (visible) beat pattern which, it is stated, is due to the vision carrier beating with the sound carrier at the vision carrier detector 7 (Fig. 1) and producing a beat which, although outside the monochrome and chrominance bands, produces a visible beat pattern by beating with one chrominance sub-carrier in the chrominance detector 11 (and not, as previously thought, due to the chrominance sub-carrier involulated on the vision I.F. carrier beating with the sound carrier), is substantially eliminated by providing a rejector circuit at the input of the chrominance band-pass amplifier 10 which attenuates (30dB) signals having a frequency equal to the difference between the vision and sound carriers, this frequency being 3.5 mc/s. in the case of the British version of the N.T.S.C. system. With such an arrangement the sound rejection ratio produced by the vision I.F. amplifier 6 need only have a value between 20 and 60 instead of about 300 which would be required in the absence of the rejector circuit and the design problem of the amplifier is consequently eased. Fig. 2 shows essential circuit details of blocks 6, 7 and 10 of Fig. 1, V1 being the last stage of amplifier 6, V2 the vision detector 7 and V3 the first stage of the B.P: chrominance amplifier 10, the cathode circuit of which includes a rejector circuit LC tuned to the frequency to be attenuated, viz. 3.5 mc/s.

Abstract: 1378380 Making buttons J R GAUNT & SON Ltd 10 Feb 1972 [16 Feb 1971] 4775/71 Heading B3A [Also in Division C7] A method of making metal buttons 10, Fig. 1, of the kind which include a metal shell or front 12, a metal backing 14 and a metal shank 16 secured to the backing comprises making an aluminium shell or front, aluminium backing and shank, assembling the shell, backing and shank together, securing them together to form a button, and subjecting the buttons to an anodizing or an electro-plating operation. The metal shank 16 is formed from wire using a wire bending machine to provide a loop 18, Fig. 2. The backing 14 is pressed from a flat metal strip to the required configuration and the shell is made using conventional press tools and may be plain or suitably embossed. The button is assembled by manually inserting shank ends 22 and stem 20 into aperture 32 of the backing and then spraying and clinching the ends using suitable tools. The backing is then inserted into the shell, Fig. 3 (not shown), and placed in a lower die (44) while an upper rolling tool (46) mounted on a press ram rolls over the peripheral portion 40, the complete overlapping of portion 40 and rebate 26 being made in a lower die (50), Fig. 4 (not shown), with a rolling and clinching tool (52). The assembled button is then anodized or electro-plated during which time they are supported by means of electrically conducting wires, or alternatively, supported in jigs (62), Fig. 5 (not shown), comprising spring-urged fingers (64). Although it is preferred to electroplate chromium, other metals may be plated and when chromium plating the current density may be doubled compared with that normally employed and then, after a few seconds, the current density is reduced to that normally used for chromium electro-plating. After the plating or anodizing operations any liquids which have penetrated into the buttons can be removed through drainage apertures 36 in the backing.

Inventor: POOLE ANTHONY GERALD
IPC: D06M13/207
Filed: 1967-02-01
Abstract: 1,205,251. Viscose rayon fibres. COURTAULDS Ltd. 31 Jan., 1968 [1 Feb., 1967], No. 4905/67. Heading B5B. Viscose rayon fibres are rendered less liable to discolour during sterilization by impregnating them in the never-dried state with a solution of sodium borohydride or an α-hydroxy carboxylic acid, e.g. lactic or citric acid and then drying them. The process is preferably applied to never-dried fibres in the course of the spinning process and may be applied simultaneously with a finishing agent e.g. a sorbiton ester-ethylene oxide condensate, immediately before the fibres are dried. If the spinning process includes a bleaching step the treatment is applied later. The fibres may then be sterilized either by heating them in steam at 120‹ C. for 30 minutes or by washing them in distilled water at 20‹ C. with mild agitation for 30 minutes, washing them with fresh water for 2 minutes, centrifuging and then heating at 120‹ C. in steam for 30 minutes.

Abstract: 608,177. Training aviators. MARTIN, J., and MARTIN-BAKER AIRCRAFT CO., Ltd. Feb. 18, 1946, No. 4961. [Class 4] Testing apparatus for use in connection with the launching of personnel from aircraft comprises upwardly directed inclined guides 1 mounted on a supporting frame as described in Specification 583,258. It is used with launching gear such as that described in Specification 583,257. The guides 1 are provided with facing strips overhanging their inner edges to form channels for the rollers 21 on the seat 20. A series of stops 22 are formed on one strip, to be engaged by sprags 23 on the seat to prevent its downward movement, and retain it at the highest point to which it is propelled. A sliding bogie 30 is located above the seat and is suspended by a cable 28 passing over a pulley at 26 and thence down to the winding gear 27. The bogie carries a pivoted suspension hook 34 engaging a shackle 40 on the seat. The shackle has limited sliding movement in an extension 41 of the seat back, and is interconnected by lever 45, telescopic spring link 46 and lever 47 to the sprags 23 which are loaded by springs 53. Initial movement of the shackle 40 only shortens the link 46 and releases the sprags 23 so that the weight of the seat is taken by the winding gear. In operation, the bogie 30 is normally at the top of the guides so that when the launching gear is operated the seat is retained at the top of its upward movement, by engagement of the sprags 23 with the ratchet teeth. The winding gear is then operated from the ground to lower the bogie until the suspension hook is engaged, after which the bogie is slightly raised to release the sprags. The seat may then be lowered by the winding gear.
