Title: Process for the production of foaming agents from cereal proteins
Inventor: EVANS CYRIL HARRY
IPC: A23J1/12
Filed: 1958-02-18
Abstract: A foaming agent is prepared by digesting a cereal protein in the cold with water containing lime for up to 24 hours, the amount of lime being in excess of and preferably at least ten times that required to form a saturated solution, whereby a soluble portion constituting the foaming agent and an insoluble portion are formed, and thereafter separating the two portions. The foaming agent present in the soluble portion may be precipitated by acid and then redissolved in water containing lime; the solution of the foaming agent may then be concentrated under reduced pressure and spray-dried.  Whole wheat, rye, barley, oats, rice or maize ground to a meal or cereal bran, flour or gluten are mentioned as sources of cereal protein.  An example is directed to the digesting of wheat gluten for from 3 to 24 hours in the cold under vacuum or other conditions preventing the formation of foam; the soluble portion obtained was separated by centrifuging and spray-dried to yield a reconstitutable powder. Other examples are concerned with the treatment of ground wheat bran and cereal flour.ALSO:A foaming agent, e.g. for meringues, is prepared by digesting a cereal protein in the cold with water containing lime for up to 24 hours, the amount of lime being in excess of and preferably at least ten times that required to form a saturated solution, whereby a soluble portion constituting the foaming agent and an insoluble portion are formed, and thereafter separating the two portions.

Title: Control means for moving a movable member from any one into any other of a first, second and third consecutive positions, for example in a reverse gear operating system for marine engines
IPC: B63H21/22
Filed: 1954-02-22
Abstract: 755,250. Electric selective signalling. PARSONS, J. B. Feb. 22, 1954, No. 5185/54. Class 40(1) [Also in Groups XXIV and XXXVII] The operating lever R of a reversing gear is moved between its forward, neutral and reverse positions by mechanism including a reversible electric motor 10 controlled by a three-way manual switch 25 in series with selector switch gear 17 operated by a rod 16 connected to lever R. The motor 10 may actuate lever R directly through toothed gearing or through a screw-and-nut connection, but as shown in Fig. 3, the motor drives a pump discharging, according to its directions of rotation, to one or other end of a double-acting fluid servomotor 13, the piston rod 14 of which is connected to lever R. The switch gear 17 comprises a casing with four pairs of contacts 21-22, 21a-22a, 29-29a and 30-30a, contacts 29 and 30 being connected respectively to the forward and reverse contacts 32 and 31 of switch 25, contacts 21, 21a being connected to the neutral contact 24 of switch 25, contacts 22, 29a being connected to the forward relay 10a of motor 10 and contacts 22a, 30a being connected to the reverse relay 10b of motor 10. Rod 16 carries four slidable contact discs 27, 28, 33, 37 has an enlargement 20 between discs 27, 28, and carries two adjustable abutments 18, springs 35 and 36 being arranged between discs 27, 37 and 28. 33, Fig. 4 shows the parts in neutral position, with discs 33 and 37 bridging across the contacts 29-29a and 30-30a while discs 27, 28 are held away from the other contacts by the enlargement 20. If switch 25 is now moved, for example, to forward position, relay 10a is energized and motor 10 turns forwardly to cause lever R to turn anticlockwise engaging forward gear. During the consequent rightward movement of rod 16 disc 37 remains in contact with contacts 30, 30a, disc 27 is moved further away from contacts 21, 22 disc 28 moves into contact with contacts 21a, 22a, and, at the end of the movement, the left-hand abutment 18 moves disc 33 away from contacts 29, 29a, so de-energizing the motor. the parts now occupying the positions shown in Fig. 5. If now switch 25 is moved back to neutral position, reverse relay 10b is energized via discs 28, and the motor turns reversely until the enlargement 20 moves disc 28 away from contacts 21a, 22a, to de-energize the motor. In a modified form of selected switch, rod 16 has secured thereto a carrier for three spring-loaded longitudinally-arranged contact strips co-operating with the four pairs of contacts.

Patent GB-806625-A (GB)
Title: Improvements in automatic means for controlling the braking of rail vehicles
IPC: B60T7/18
Filed: 1957-02-15
Abstract: 806,625. Railway braking systems. SOC. INDUSTRIELLE DE LIAISONS ELECTRIQUES, and HOURS, G. E. Feb. 15, 1957 [Feb. 16, 1956], No. 5251/57. Class 103 (1). An automatic braking system for railway vehicles, the basic principles of which are shown in Fig. 1, comprises pairs of inductors 1 and 2, of which the inductors 1 is of permanent magnet type and the inductors 2 of coilexcited type arranged at distances D1, D2, D3, and D4, along a track in approach to a signal S, the coil inductors being arranged to neutralize the effect of the inductors 1 if the signal is " down " or is in a position to pass a train. The system works on the principle that a train may be allowed to pass at certain pre-determined maximum speeds up to the distance D2, D3 and D4 from a signal S without braking, such speeds being represented by the height of the shaded areas in the diagram. Assuming, however, that the speed-distance plot of a train is represented by the dotted line curve, braking must be carried out at any time this curve crosses a shaded area and the braking and circuit control means for carrying this out are shown in Figs. 3 and 4. In Fig. 3, the passage of a detector magnet 35 on the train past a permanent magnet inductor 1 releases the armature 31a so that under the effect of spring 30, it closes contacts 24, 25 for a short period. This is, however, sufficient to energize solenoid coil 22a so that holding contacts 23 are closed and contacts 8, 12 opened. Current supply to solenoid 14, which controls a mechanism 17, whereby the brakes are applied, is therefore passed from a source B only through contacts 9, 13. These contacts are opened to produce a brake application, if at any time, the speed of the train is such that the E.M.F. produced by generator 33 acting in the coil 32 of solenoid 32a is sufficient to overcome the force of spring 11. When a train initially passes its detector 4 over the first inductor 1, contact 26 is switched over from b to c and also, if the coil inductor 2 is energized, it closes a contact a which operates a general cancelling relay A having a movable contact 27. Pairs of relays DIX1, D2X2, D3X3, are associated with each section of the track between successive pairs of inductors, the last zone being controlled by a single relay D4, the relays affecting operation of contacts C1, C2, C3. The contacts C3, in co-operation with. contacts V1, V2, V3, operative by relay V100, V65 and V30, responsive to particular speeds of the generator G driven by the vehicle wheels, act to energize a solenoid F1 controlling a high-speed braking electrovalve in a manner appropriate to the speed of the train and its position on the track. A further solenoid F2, provided for braking at speeds lower than 30 km.hr. has a single energizing circuit through the contact C3 of the last relay D4. Rearming relay Re and relay Rg exercise overall control of the pairs of relays DiX and the operation of the generator G. Specification 804,427, [Group XXX], is referred to.

Title: Improvements relating to the production of basic zinc chromate
IPC: C01G37/14
Filed: 1941-04-24
Abstract: 547,859. Basic zinc chromate. NON-FERROUS METAL PRODUCTS, Ltd. April 24, 1941, No. 5313. Convention date, April 29, 1940. [Class 1 (iii)] A basic zinc chromate which is a chemical individual and has the formula 5ZnO.CrO 3 .4H 2 O is made by stirring 500 kg. zinc oxide into 5000 litres of water and adding rapidly 125 kg. chromium trioxide, CrO 3 , dissolved in 150 litres of water.

Title: Improvements in or relating to stabilization of floating bodies
Inventor: BELL JOHN
IPC: B63B39/03
Filed: 1962-02-13
Abstract: 1,020,451. Stabilizing ships. MUIRHEAD & CO. Ltd. Jan. 25, 1963 [Feb. 13, 1962; Feb. 13, 1962], Nos. 5454/62 and 5455/62. Heading B7M. A floating body comprises a stabilizer tank the bottom of which is open for communication with the sea, and means for controlling the displacement of water in the tank for opposing rolling or pitching, characterized by means mounted on the body for displacing the water in the tank by gas under pressure greater than atmospheric. A valve 8 controlling the flow of gas between stabilizer tanks 2, 3, is controlled by a velocity or rate gyroscope 9 such that when the latter 9 is in a central position, the roll velocity is zero, i.e. the body is at the extremity of a roll either to port or starboard. An arm 10 will then be central and opposing contacts 15, 21; 15<SP>1</SP>, 211 will be open and a solenoid coil 25 will be de-energized and the valve 8 will remain open. When the ship returns to the vertical, the arm 10 is deflected, e.g. to the left, the upper portion 14 will be deflected to the right and the contacts 15<SP>1</SP>, 21<SP>1</SP> will meet, energizing the coil 25 and closing the valve 8. As rolling continues, the portion 14 will engage a stop 23<SP>1</SP> and with further movement a plate 20 will be forced to move to the right. As the end of the roll is approached the portion 14 moves to the left breaking contact between 15<SP>1</SP> and 21<SP>1</SP>. Because plate 20 has been moved to the right, contacts 151 and 21<SP>1</SP> separate before arm 10 has regained the central position and thus the opening of valve 8 has been advanced in phase. The contact gaps, the distances between stops 23 and 23<SP>1</SP> and the amount of travel of plate 20 can be adjusted for optimum sensitivity and advance. In Figs. 9 and 11 (not shown) fins are shown in the region adjacent the opening in the stabilizer tanks. These fins are coupled together and operated by power means so that when it is desired to fill a tank, the forward edges of the fins are tilted downwards while at the same time fins attached to the corresponding tank on the opposite side of the body are tilted in the opposite direction to drain water from the tank. Fig. 8 shows an embodiment of an anti-pitching tank. Air chamber 46 is located above tank 39 in the bow of a ship 40 and is kept under pressure from air pump 47. Openings 41 allowing access to the sea are provided and stop valve 42 is located in the top of the tank 39, the stop valve being operated by a control system as indicated in Fig. 7 but in which the sensing means is sensitive to motion about the pitching axis of the ship.

Abstract: 230,090. Tagliabue Manufacturing Co., C. J., (Assignees of Bast, F. J.). March 1, 1924, [Convention date]. Void [Published under Sect. 91 of the Act]. Fluid-actuated valves. - Valve apparatu,s for controlling a series of operations in a plurality of tanks consists of a number of air-pressureoperated valves and lever-cam devices actuated by clock-mechanism. The application to the pasteurization of milk is illustrated, the operation being such that when a cycle is completed in one tank, an intermediate point is reached in another, and the first step is occurring in another. The cycle with regard to the tank 10 is as follows :-The cam 27 is rotated by a clock 41, the lever 25, Fig. 4, is rocked about its pivot 26, a ball valve 19 is moved and air in a chamber of the inlet valve 13 is released. The tank 10 is thereupon filled with milk. Similarly a valve 15 is operated by a compound lever 31, 33, Fig. 3, to admit hot water to heating coils in the tank. The temperature is regulated by a thermostatic bulb 39 connected by a capillary tube 38 to a capsular spring 37 or like device, the lever 33 moving the air valve 22 according as more or less heat is required by the milk in the tank. The arrangement is such that both the filling of the tank and the heating to pasteurizing temperature require the same time, say 30 minutes. At the end of this time the cams allow the valves 13 and 15 to close. The outlet valve 17 is then opened by the action of a cam 30. The mechanism controlling the operations in the tanks 10<a> and 10<b> is similar.
