Patent GB-699692-A (GB)
Title: Improvements in and relating to protein food products
IPC: A23J3/28
Filed: 1950-09-26
Abstract: Food products resembling meat are obtained by preparing filaments of protein, exemplified by oil seed protein such as soya bean or groundnut protein, casein, gluten, protein from maize, fish protein, and applying to the filaments an edible substance such as a starch, flour or dextrin, a protein, a gum, an alginate, or carboxymethyl cellulose which holds the filaments in place.  Appropriate "chewiness" of the product is imparted by stretching as the filaments are being formed.  The filaments may be tenderized by partial hydrolysis with a proteolytic enzyme, hydrochloric acid, sodium sulphide, or alkali hydroxide.  Meat flavourings, colourings, and additional nutrients such as vitamin concentrates, dried milk and amino acids may be incorporated. Fat may be applied to the filaments. The filaments may be assembled to bundles, e.g. to tows of 3-4 in. diameter. According to one example, a product which simulates white meat of chicken is obtained by forcing a solution of casein through spinnerets into a solution of acetic acid and sodium chloride to form three bundles of filaments, uniting the bundles and stretching 150 per cent, immersing in 12 per cent sodium chloride solution, squeezing excess solution from the filaments, immersing in a bath of water, skimmed milk powder, egg albumen, sugar, sodium chloride, monosodium glutamate, chicken flavour, and yellow food dye, draining, placing in a mould with the filaments parallel, and compacting at 170 DEG  F.  According to another example, a product simulating roast beef is obtained from stretched filaments spun from a solution of protein from oil-free peanut meal, by immersing the filaments in a bath of beef broth, skimmed milk powder, egg albumen, wheat flour, sugar, sodium chloride, beef dripping, monosodium glutamate, and brown food dye, drying, passing the filaments so treated through a molten mixture of hydrogenated vegetable oil and beef fat previously browned, and, after chilling and making holes along the direction of the filaments, again immersing the product in the molten fat.

Title: Improvements in sensitive photographic materials
IPC: G03C1/035
Filed: 1947-08-26
Abstract: 635,849. Sensitive photographic material. KODAK, Ltd., and KNOTT, E. B. Aug. 26, 1947, No. 23616. [Class 98 (ii)] The tendency for a visible image to develop in a " Type I " emulsion (i.e. one which forms latent image mostly inside the grains) on development in a surface developer is reduced or eliminated by mixing with such enulsion before coating and exposure, up to 15 per cent, a less sensitive emulsion of any type (calculated as the silver contents of the two emulsions), the relative speeds of the two emulsions being such that when both emulsions are exposed to the amount of light necessary to produce substantially maximum density in the more sensitive emulsion in a specified internal developer which includes metal, hydroquinone, and hypo for 4 minutes at 20‹ C.., the less sensitive emulsion gives no measurable density when treated for 4 minutes at 20‹ C. in the same developer without the hypo (i.e. a surface developer). The material may contain more than one " Type I emulsion, and these emulsions may have different colour sensitivities. In example 1, to 3500 ccs. of a fast " Type I emulsion made as described in example 1 of Specification 635,841 is added 500 ccs. of a " Type II " fine-grained slow silver chloride emulsion (i.e. one which forms latent image'mostly on the surface of the grains). In example 2, the procedure is similar, using a fine-grained slow silver bromide emulsion which forms both internal and surface latent image. Specifications 581,772 and 581,773 also are referred to.

Title: Fuel control system
IPC: F02D1/04
Filed: 1974-05-28
Abstract: 1476363 Fuel control NIPPONDENSO CO Ltd and KOMATSU SEISAKUSHO KK 28 May 1974 [30 May 1973] 23661/74 Heading G3B A fuel control system for controlling a fuel control rod 2 in a fuel injection pump 1 comprises a link 12 for moving a lower fulcrum 17 of a floating lever 16 connected to rod 2, a return spring 14 adapted to move the fulcrum in a direction to reduce the fuel injected, a start spring 20 adapted to move lever 16 so as to increase the fuel, and a damper spring 26 adapted to bias lever 16 in the same direction as spring 20. In operation, with the engine idling, a lever 8 connected to the accelerator lever of the engine is turned clockwise, thus reducing the tension in a spring 9, but allowing a spring 25 to urge a lever 5, a spring 24 and a block 21 against the thrust of centrifugal weights 23. When the engine is accelerated, lever 8 is turned anti-clockwise, the tension in spring 9 is increased so that lever 5 is pivoted clockwise about a point 6 until it abuts a full load stop 7. This movement of lever 5 causes leftward movement of block 21 so as to pivot a lever 19 clockwise about point 6, which pivots lever 16 anti-clock wise about the fulcrum 17 by engagement of a pin 18. The biasing force of compression spring 26 is removed and the biasing force of tension spring 20 is reduced so that link 12 pivots about a fixed fulcrum 15 in the clockwise direction and the fulcrum 17 of floating lever 16 is also moved in the clockwise direction into the Fig. 2 position (not shown). However, since the force of spring 20 is larger than the force of spring 14, link 12 is gradually pivoted in the anti-clockwise direction, so that the leading end of an elongated groove 12a in the link engages the body 4 of the governor Fig. 3 (not shown), and lever 16 is simultaneously pivoted about pin 18 in the anti-clockwise direction so as to move rod 2 in the high speed direction a. When the engine is in full load condition lever 16 is stable in the (Fig. 3) position. When the engine is decelerated, lever 8 is turned clockwise, the tension of spring 9 is reduced, lever 5 is pivoted by the thrust of weights 23 in the anti-clockwise direction , and simultaneously lever 19 pivots in the anti-clockwise direction. The upper end of lever 16 is therefore moved in the clockwise direction and the fulcrum 17 is slightly moved in the clockwise direction. Damper spring 26 engages lever 16 thus restricting the clockwise movement of fulcrum 17 on the lever so that when the engine is decelerated, the position of the fulcrum is substantially fixed and the amount of injected fuel is quickly reduced.

Title: Improvements relating to filters
Inventor: WILKINSON DEREK ANTHONY CUNLIF
IPC: B01D35/02
Filed: 1961-07-07
Abstract: 993,849. Filters. LEDWARD & BECKETT Ltd. June 27, 1962 [July 7, 1961], No. 24714/61. Heading BID. A filter includes a pair of screens arranged in the form of a V and mounted in a casing having inlet and outlet ports, so that the pair of screens can move between two positions in which the inlet port is on opposite sides of the apex of the V, while the outlet port communicates with the space between the limbs of the V in both positions. The screens may be arranged to move linearly in a casing of uniform cross-section, or preferably, arranged to turn about a pivot in a cylindrical casing. Thus, in one position, one screen is between outlet and inlet ports, while the other is between outlet port and a stagnant pocket. In the other position, the role of the screens is reversed. Preferably a flushing valve is provided in each of the stagnant pockets of the casing so that momentary opening of the appropriate valve to a low pressure region, e.g. a drain, causes a reverse flow through the inoperative screen and washes dirt therefrom. In one embodiment, Fig. 1, the screens and casing form a selfcleaning strainer box for use in e.g. a cooling water circulating system. The box comprises a casing 10 having inlet and outlet ports 14 and 15, provided with pipe connecting flanges 16 and 17. Within the casing, a frame comprising screens 18 and 19 is mounted on a pivot 22 so that the screens can be rocked between the two operative positions shown in Figs. 1 and 5. In one end plate of the casing, are mounted flushing valves comprising ports 26 and 27 covered by arcuate plates 28 and 29 connected to the frame that carries the screens. The extent of the plates is such that the ports are covered in both operative positions of the screens, but if the pair of screens is moved beyond one operative position, the flushing valve of the inoperative screen is opened, Fig. 6. Thus, with the screens in one operative position, Fig. 1, liquid flows through screen 19, which collects dirt on its outer surface. When the screen becomes clogged, the screens may be moved to and momentarily beyond the other operative position, Figs. 5 and 6, so that the screen 18 becomes operative and, due to the opening of the flushing valve, dirt is washed from screen 19 by reverse flow. The movement may be effected manually or automatically. In a preferred arrangement, a pressure drop across the strainer caused by clogging of a screen causes a pressure differential switch to actuate a motor connected via a cam and connecting rods to the central shaft 22 so that a change-over to the clean screen, and a momentary reverse flow through the dirty screen, are effected, leaving the latter screen in readiness for the next change-over.
