Title: Texturizing process for single cell protein products
IPC: A23J3/26
Filed: 1971-04-27
Abstract: 1322125 Proteinaceous foods STANDARD OIL CO 27 April 1971 [27 April 1970 19 June 1970] 11579/71 Heading A2B [Also in Division C6] A process for imparting texture to proteincontaining microbial cells broadly involves preparing an aqueous cell paste, extruding the cell paste and conditioning the extruded paste as by cooling, heating and/or drying (also oxygenation or alkali/acid baths) to induce the formation of a texturized product. Where no broken cells are initially present, the paste should at some stage be subjected to shearing either as a concomitant of the extrusion or in other conventional equipment. The aqueous cell paste may typically be heat-treated at a temperature of from 150‹ to 400‹F for from 10 to 300 seconds whilst applying to the cells a shearing force corresponding to a shear rate of from 10 to 60 rpm and a torque of from 200 to 2,000 meter-grams. Heat treatment of the extruded cell paste (where practised) may involve up to 30 minutes at 180‹-300‹F. Preferred species of yeasts and bacteria are mentioned. Examples I, II and III describe the shearing extrusion of Torula yeast pastes into threads. The threads were conditioned by cooling and drying in an oven to a crisp texture. Upon immersion in water, the textured product did not revert into single, individual cell form. Soybean protein, and wheat flour and salts, where included in the original cell paste according to Examples II and III, respectively. In Example VIII a Torula yeast paste containing a substantial preparation of broken cells was extruded at temperatures of 80‹ or 212‹F and the extruded pastes were subjected to specified heating treatments and then cooled. It is stated that the pastes may also include oils, fats, emulsifiers, and flavouring and colouring agents which enhance the properties of the final product. The textured extrudate may be bleached, cooked or deep-fat fried to prepare a food product.

Abstract: 1,142,478. Combined sound and picture apparatus. EASTMAN KODAK CO. 17 March, 1966 [19 March, 1965], No. 11668/66. Heading G5R. A sound recording and/or reproducing apparatus comprises a sound transducer head 46, means such as a roller 45 adjacent the head for applying a motion resisting force to a web, e.g. a film strip F, carrying a sound track and means, e.g. teeth 36, for pushing the web past the head against the motion resisting force. As shown film strip F for a motion picture camera or projector has a sound track along one edge and regularly spaced perforations along the other edge for engagement by teeth 36 on a sprocket 21. A record/playback head 46 is spring urged against the sound track portion of the film to press this edge of the film into contact with a peripheral surface 38 of sprocket 21. The film strip F is advanced intermittently through a film gate by a claw 30 on a reciprocating member 26 which engages successive perforations in film strip F. A pressure roller 45 which has its axis canted relative to the rotational axis of sprocket 21 urges the film strip into contact with surfaces 38, 42, Fig. 6, of the sprocket at angularly spaced locations. The force exerted by spring urged head 46 causes film strip F to rise away from surface 38 immediately in front of and behind head 46, so that if sprocket 21 is formed with peripheral surfaces 38, 42 of smaller diameter than the root diameter of teeth 36 only the sprocket teeth between pressure roller 45 and record/play head 46 serve to advance the film strip in this region.

Title: Improvements in or relating to electric amplifying systems
IPC: H03F1/54
Filed: 1940-07-16
Abstract: 540,193. Public address systems. STANDARD TELEPHONES & CABLES, Ltd. July 16, 1940, No. 11759. Convention date, July 18, 1939. [Class 40 (iv)] Two groups of loudspeakers constituting loads L1, L2 are fed by two amplifiers 12, 13 through a bridge network 30 having the loads as one pair of opposite arms and resisances R1, R2 as the other pair of opposite arms, the outputs of the amplifiers being applied across the two diagonals. The impedances of the four arms are all substantially equal, and the internal impedance of each amplifier has preferably the same value. Under normal working conditions, each load receives equal amounts of current from the two amplifiers and no current flows through the resistances R1, R2. It is shown that if either load is disabled, either by a short-circuit or by an open-circuit, the other load receives the same input as under normal conditions, while the impedance match is not seriously affected. If either amplifier is disabled, either by a short-circuit or by an open-circuit, the remaining amplifier works into the normal load impedance and the input of each load suffers a loss of 6 decibels. This may however be reduced by 3 decibels by short-circuiting the resistances R1, R2. The amplifiers are fed in parallel from a number of transmitters 9 through a volume control 11. Further amplifiers 31-34 connected as shown in Fig. 1A may be inserted between the amplifiers 12, 13 and the bridge network 30. U.S.A. Specification 1,900,106 is referred to.
