Abstract: 834,606. Automatic television control systems. FERNSEH G.m.b.H. Sept. 17, 1957 [Sept. 19, 1956], No. 29236/57. Class 38 (4). In a system for automatically controlling colour television signals, a signal corresponding to the sum of the excess amplitudes of any colour component signals which exceed a predetermined amplitude, controls the intensity of light producing the television signals. In Fig. 1, a white dot pattern produced on the screen of the cathode-ray tube 1 of a flying spot scanner is projected on to a transparent colour picture 3, light from which is resolved into red green and blue colour components by mirrors 4 and 5 and transmitted to photo-cells 11, 12, 13 which, in conjunction with amplifiers 14, 15, 16, produce three colour component electrical signals r, g, b. These signals are applied to a thermionic valve circuit 17 in which biased rectifiers are so arranged that if any colour component signal exceeds a predetermined, the excess signal, or the sum of the excess signals, if there is more than one, is rectified and applied to vary the light projected on to picture 3 either by controlling the grid of the cathode-ray tube as shown, or by controlling the aperture of a light stop or the transmission of a light filter between the cathode-ray tube and the picture. Details of circuit 17 which includes black level clamps are described with respect to Fig. 2 (not shown).

Abstract: 319,782. Loewe - Radio Ges., and Emersleben, O. Sept. 28, 1928, [Convention date]. Drawings to Specification. Thermionic amplifiers.-In a resistancecoupled amplifier, maximum voltage amplification per stage is secured by choosing a valve with an amplification factor of 100 or more determined by a formula involving the product of the coupling-resistance, the plate battery voltage, and the cathode emission. Preferably, a valve having an equipotential cathode is employed, and the grid bias may be zero, or a small negative value derived from a potentiometer across a 1 ¢ volt cell. A mathematical analysis of the problem and the resulting formulµ for the amplification factor are given in the Specification. Specification 129,313 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) refers to the use of valves having extra grids for giving high amplification factors.

Abstract: 537,423. Blood food preparations. WEIZMANN, C. Nov. 20, 1939, No. 30441. [Class 49] A food preparation is made by subjecting animal blood or serum thereof to a predigestion or presolution treatment with proteolytic enzymes, such as papain, bromelin or pepsin, and afterwards to the action of yeast enzymes, e.g. by treatment with an active yeast autolysate, to effect further proberlytic degradation. The enzymes used in the presolution stage may be activated, e.g. papain activated by yeast autolysate, and the blood, diluted with water, may be sterilized or pasteurized before treatment with the enzymes. As blood contains proteolytic enzymes pretreatment with papain &c. may be replaced by a period of incubation during which action of the blood enzymes occurs. The process may be carried out in the presence of antiseptics such as toluene, chloroform, ether &c. Specifications 450,529, 478,570, 509,495, [Group IV], and 529,775 are referred to.
