Abstract: 994,545. Forms of wood; laminates. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Dec. 12, 1963 [Dec. 15, 1962], No. 49146/63. Headings B5L and B5N. A three-dimensional object in moulded laminae, such as -wood veneer, including a corner portion comprises a number of first layers L which are continuous around the corner, and a number of second layers which are discontinuous around the corner, each second layer being formed by two distinct pieces T, T<SP>1</SP> each having a tapered overlapping end section at the corner. The length of overlap of any second layer is a function of the distance of that layer from the innermost layer of the corner. The object may comprise a piece of furniture, such as a radio or television cabinet, each wall having a number of glued layers of wood veneer T, T<SP>1</SP>, L. The layers L are continuous around the corner and have the lengths of their grain fibre extending longitudinally around the corner. The discontinuous layers T, T<SP>1</SP> have their grain extending parallel to the length of the corner and each piece T, T<SP>1</SP> has its end portions tapered and overlapping the other piece forming its layer. The thickness of the overlapping portions is chosen so that the whole corner is filled with the material of the layers and the innermost and outermost surfaces of the corner have sharp angles as shown or have the same radius. The overlapping portions may be smaller than shown so that the outermost surface has a rounder portion. The layers may be moulded in a press.

Abstract: 1,157,947. Streptococcus hemolyticus of high anti-tumour activity. CHUGAI SEIYAKU K.K. Oct. 30, 1967 [Oct. 31, 1966], No.49275/67. Heading C6F. A process for obtaining cells of hemolytic Streptococci having high anti-tumour activity involves cultivating hemolytic Streptococci having anti-tumour activity, particularly Streptococcus hemolyticus ATCC No. 21060, in a culture medium containing a yeast extract, and separating bacterial cells from the cultivated broth. The yeast extracted may be obtained by dissolving a commerically available yeast extract or auto-lysate in water, neutralizing and heating the solution, and then taking away the insoluble fraction by filtering. The culture medium of pH 7À0-7À4 typically contains between 3 and 6 grams per decilitre of yeast extract and such other constituents as peptone, fish meat extract, beef extract, horse or whale flesh extract, ribonucleic acid and/or its ribonuclease core, sodium chloride, sodium hydrogen phosphate and sodium hydrogen carbonate. The hemolytic Streptococci may be preliminarily cultivated in a yeast extract medium or beef infusion medium at 37‹ C. for 24 hours. The main cultivation is then carried out at 37‹ C. for periods ranging from 10 to 30 hours (according to circumstances). The separated cells are suspended in a medium containing penicillin and heated at 30-38‹ C. for 10-30 minutes and then at 40-50‹ C. for 20-40 minutes to eliminate their virulence and hemolysin-producing activity. A suitable suspension medium (Bernheimer's Basal Medium) is composed of (a) 6 ml. of a solution consisting of 675 mg. of maltose and an aqueous solution containing 20 grams 1 decilitre of potassium dihydrogen phosphate, adjusted to pH 6À9-7À0 with sodium hydroxide, (b) 12 ml. of an aqueous solution containing 2 grams 1 decilitre of magnesium sulphate heptahydrate and (c) 66 ml. of distilled water.

Abstract: 1528936 FET circuits INTERNATIONAL BUSINESS MACHINES CORP 8 Dec 1975 [20 Dec 1974 (2) 50203/75 Heading H3T [Also in Division H1] The output node of a FET circuit having substantial capacitance is connected to a negative feedback amplifier to provide a current path in parallel with and of less impedance than said output capacitance. This limits the voltage swing at the output node and thereby speeds switching. According to the invention, the amplifier is a CMOS inverter 20, 22, Fig. 3a with negative feedback between input and output which, as described, may be provided by a resistor or resistor connected FETs 16,18. The channel ratios of FETs 16, 18 may be chosen independently to obtain a desired characteristic between i in  and V o . In another embodiment, FETs 16 and 18 are replaced by a linear or nonlinear resistor, Fig. 2 (not shown). The feedback amplifiers are described connected to the output node between a pull up FET and various FET networks for providing simple and complex logic functions, Figs. 4-9 (not shown). They may also be applied to various logic functions in the accessing reading and writing in a random access memory matrix comprising cross-coupled FET storage cells. Figs. 10-14 (not shown).
