Title: Process for preparing texturized flaked protein material
IPC: A23L7/10
Filed: 1975-01-16
Abstract: 1487618 Texturized protein flakes GENERAL MILLS Inc 16 Jan 1975 [16 Jan 1974] 1950/75 Heading C3H [Also in Division A2] A method for preparing a texturized, flaked protein material comprises expanding a protein material to form texturized expanded particles of the protein material and then forming the texturized, expanded protein material thus obtained into flakes whilst in a pliable condition. Preferably the flaking is carried out immediately after texturizing but previously texturized protein material may be conditioned prior to forming into flakes by maintaining the protein material in a steam chamber until it becomes pliable.

Title: Improvements in or relating to measuring devices
IPC: G01R1/30
Filed: 1946-01-21
Abstract: 629,246. Electric counters. STANDARD TELEPHONES & CABLES, Ltd., DUNN, R. H., and McWHIRTER, E. M. S. Jan. 21, 1946, No. 1986. [Class 106 (i)] An electrical quantity-measuring device is adapted to integrate received quantities which vary in magnitude and to measure by automatically subtracting a predetermined quantity at intervals from the integrated total and counting the number of subtractions so made. The invention is applied to measuring the amount of fuel supplied to a furnace by a number of automatic stokers varying in capacity. The operation of any stoker connects terminals A, B, C to a corresponding set of terminals to tap off an amount of a potentiometer corresponding to the capacity of the stoker. A contact 1RL makes and breaks to charge a condenser CC1 negatively from the potentiometer and to discharge it to a point IT connected to the control grid of a pentode PV, the anode of which is connected to a continuously-discharging neon cold cathode tube NT, so that as the potential of the point IT is decreased by the discharging of the condenser CC1, the potential of a point OT rises. When the potential at OT rises sufficiently due to successive operations of the automatic stokers, a cold cathode tube CCT fires to energize a relay A which operates a counter M and energizes a slow-release relay B which releases the relay A and discharges a positivelycharged condenser CC2 to the point IT to reduce the potential at OT by an amount corresponding to the adding of one unit to the counter M, the tube CCT then snuffing out. The cold cathode tube CCT may be replaced by a triode or pentode trigger circuit. Specification 629,244, [Group XXXVI], is referred to.

Title: Improvements in or relating to recording instruments
Filed: 1939-01-20
Abstract: 524,047. Recording-apparatus. FOSTER INSTRUMENT CO., Ltd., and FOSTER, C. E. Jan. 20, 1939, No. 2028: [Class 106 (iv)] In recording instruments of the kind in which the recording arm is periodically depressed to mark the record chart means are provided for automatically impressing upon the moving system of the instrument a mechanical force for the purpose of bringing the moving system to its true position of deflection to eliminate the error due to pivot roll or " stiction," i.e. static friction. In the form shown the moving coil 3 of the instrument has conically pointed pivots 5 mounted in conical recesses of jewel bearings 7. The coil 3 carries a counterweighted recording arm 8 with a flat spring portion 11 and a stylus 9 that co-operates with a translucent chart 4 arranged in front of a carbon paper 18 and support plate 19. The stylus 9 is depressed against the chart periodically by a pivoted spring controlled presser bar 12 under the action of a cam 14. To avoid the error due to pivot roll the cam 14 is provided with a depression 20 which moves the presser bar and stylus up to the chart smoothly so as to settle the pivots in the bearing recesses. If the instrument is of the multiple record type for association with two or more sensitive devices the change-over of connections takes place at a suitable point in the cam cycle, conveniently before the gradual or non-marking depression is effected.

Abstract: 746,596. Axial flow compressors; gas turbine plant. ROLLS-ROYCE, Ltd. April 23, 1954 [Jan. 26, 1953], No. 2275/53. Classes 110(1) and 110(3) [Also in Group XXIX] In a gas turbine plant with a multi-stage compressor provided with means for introducing hot gas into the compressor inlet duct or in the region of the low pressure blading stages or both and at least one ring of adjustable pitch stator blades in the inlet duct or in the low pressure stages, the pitch of the stator blades is adjusted to increase the swirl velocity of air passing through them when hot gas is introduced for anti-icing purposes. The invention is described with reference to a gas turbine plant having a multi-stage axial-flow compressor as described and claimed in Specification 704,849 in which provision is made for adjusting the pitch of the stator blades so that for each rotational speed of the compressor, the stator blades have a corresponding pitch. The arrangement shown in Figs. 1 and 2 of Specification 704,849 is provided with the following additions. An annular manifold 100 encircling the compressor inlet is fed with hot air from the compressor delivery through a conduit 101 under control of a valve 102. The air flows from the manifold into hollow struts 108 having outlets 109 in their leading edges. The valve 102 is operated by a solenoid 103 the coil of which is connected in parallel with the coil of a solenoid 1.04 operating a valve 105. The valve 105 is located in a pipe 106 containing a restriction 107 connecting the suction and discharge pipes 18, 47 of the pump 14. The arrangement is such that when the valves 102, 105 are opened hot air is supplied to the manifold 100 and ram device 30 causes the guide vanes 24a to take up a position giving an increase swirl to the incoming air. Modifications in which the control arrangements shown in Figs. 3, 4 and 5 of Specification 704,849 are employed are also described. In a further modification in which a two-position control for the adjustable stator blades is used; a solenoid-operated valve controlling the air supply to a pneumatic ram effecting the pitch adjustment of the blades is wired in parallel with a solenoid-operated valve controlling the supply of hot gas to the compressor.
