Title: Color picture information recording and reproducing system
IPC: H04N5/76
Filed: 1965-06-10
Abstract: 1,061,604. Video recording. COLUMBIA BROADCASTING SYSTEM Inc. June 10, 1965 [June 10, 1964; June 16, 1964], No. 24641/65. Heading G5R. Information is recorded on a record medium sensitive to radiant energy by scanning with a radiant energy beam at a given line scan rate to record contiguous transverse lines and modulating the beam intensity with a modulated carrier signal whose carrier frequency is an integral multiple of the line scan rate and whose modulation represents the information to be recorded. In recording a colour picture colour information is conveyed by phase and amplitude of modulation, and brightness information is conveyed by the intensity of the modulated signal. The appearance of the record member is shown in Fig. 4. The groups of closely spaced lines 19, 20 represent colour information and the background of the frames (of which three, 11, 12, 13, are shown) represents brightness information. Any conventional sound tracks may be added at 14 and 15. In recording, the film or spot is oscillated to merge adjacent lines of scan so that in playback it is not necessary to track the original lines of scan.

Abstract: 605,273. Radio receiving sets. AKTIESELSKABET AMERICAN APPARATE CO. Sept. 24, 1945, No. 24672. Convention date, Jan. 30, 1943. [Class 40 (v)] A push-button selector for radio receivers of the type in which a number of contact slides are operated by push-buttons to connect an impedance corresponding to a push-buttun to the other circuits of the receiver, each button being locked in the depressed position until another button is pressed, is arranged so that the contact slides are radially slidable towards and away from a central common contact member. A push-button 2 is mounted on the end of a slidable rod 10, the other end of which is fastened to a connecting plate 28. A member 34, slidably mounted in a slot 36, is connected to plate 28 by a pin and slot. A pillar 43, preferably moulded in one piece with the slide 34, carries contacts 44, which engage with sector-shaped contact members 48 common to all the contact slides and mounted on an insulating column 38. The slots 36 radiate from the column 38, near which the components connected to the common contacts 48 are mounted. The coils corresponding to each push-button may be mounted on the contact slide. The push-rod 10 has a flange 12 cooperating with a coil spring which bears against a fixed bar 16 through which the rod extends, and a detent 20, which raises a locking bar 22 to release any other push-button as the pushbutton 2 is depressed. The locking bar 22 is then depressed by a spring and co-operates with detent 20 to hold the bush-button 2 depressed against the spring 14.

Patent GB-248113-A (GB)
Abstract: 248,113. Plinatus, V. Dec. 8, 1924. Celluloid, treatrnent of; plastic compositions containing cellulose derivatives. - Ornamental effects are produced in celluloid-, leather,- or rubber-like compositions, comprising cellulose derivatives and a plastifier, other than camphor, by working masses of at least two colours into each other in a dry state, with the application of mechanical energy and heat. The masses may be of the same or of different hardness, a soft mass producing blurred veins &c. on being rolled into a harder base material. The nature of the colouring material also affects the sharpness of the veins; earth colours give sharply defined markings, while aniline colours produce more indefinite tones. Bronzes and haloid salts and sulphides may also be employed as colours. Regular or irregular patterns may be produced by the use of regular or irregular shaped pieces of coloured composition. Sheets of the coloured composition may be pressed on to a support, such as wood, fabric, or the sheets may be pressed into blocks, slabs, &c. As plastifying agents are specified esters of alcohols such as ethyl alcohol, glycol, glycerine, sugars as glucose, lactose, saccharose, phenols, &c., and acids as phosphoric, formic, acetic, butyric, oxalic, succinic, lactic, malic, tartaric, benzoic, phthalic, phenol acids, salicylic, tannic, camphor acids, colophenic acids, naphthenic acid. Fillers, oils, rubber, bitumens, resins, &c., may also be employed in the making of the compositions.
