Title: Improvements in the manufacture of a cream substitute
IPC: A23L9/20
Filed: 1942-04-15
Abstract: 555,361. Emulsions. MASON, R. D., and JUSTESEN, A. C. April 15, 1942, No. 4957. [Class 1 (i)] [Also in Group VI] A cream substitute is prepared by dispersing a basic fat blend consisting of processed butter fat and hardened vegetable oils of the leguminosae and palmae groups, e.g. arachis and coconut oils, in an aqueous gum base formed by mixing an aqueous suspension of an emulsifying agent A consisting of a harmless chloride, e.g. common salt, a. harmless salt of a tribasic acid, e.g. a phosphate or citrate such as trisodium orthophosphate. disodium hydrogen phosphate. or trisodium citrate, and a vegetable gum, preferably the sodium alginate known under the Registered Trade Mark "Manucol," with an aqueous suspension of an emulsifying agent B comprising a cellulose derivative formed by replacing a hydrogen atom of cellulose by a hydrocarbon radicle, e.g. the methyl cellulose known under the Registered Trade Mark " Tylose." or a mixed alkyl ether of cellulose, e.g. the product known under the Registered Trade Mark " Cellofas." The fats are melted and mixed in a steam-jacketed pan and glyceryl monostearate and lecithin may be included. The dry ingredients of agent A are separately sieved and mixed in the dry and the mixture heated with stirring in water at about 40‹C. The cellulose derivative is disintegrated in boiling water and, after addition of water at room temperature with stirring allowed to stand at about 50‹ C. up to 4 days. The two suspensions are mixed and then heated to about 35- 45‹C. in a pasteurizer; glycerine and water may also be included. The fat blend may be injected into the gum base, preferably through nozzles of about 0.5 mm. diam., at about 45‹ C. and a pressure of 180-200 kilograms per sq. c. The emulsion produced is passed to a storage tank, heated to about 30‹-45‹ C., or to about 70‹ C. for pasteurization, homogenized twice preferably at relatively high and low pressures, cooled to about 15‹-20‹ C. and, preferably, after an interval to 5‹-10‹ C. and finally passed to a cold storage room and allowed to mature at about 5‹ C. Colouring and flavouring, preferably mixed together, may be incorporated in the fat blend, and substances rich in vitamins, particularly vitamins A and D, may be added during the final cooling stages. The colouring may consist of a fat-soluble yellow dyestuff dissolved in melted hardened vegetable fat and filtered through muslin, and the flavouring of a mixture of ethyl esters of pelargonic and butyric acids and butyl esters of acetic and butyric acids with triacetin and diacetyl. Examples of whippable cream substitutes are given.

Title: Electrical circuit breaker having extinguishing chambers
IPC: H01H33/12
Filed: 1938-02-17
Abstract: 493,489. Arc-rupturing in switches. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET, and RONNBERG, D. Feb. 17, 1938, No. 4970. [Class 38 (v)] In a liquid-immersed switch having main contact pairs acting in extinguishing chambers and auxiliary circuit-making contacts in series therewith, the movable contact of the main contact pairs and the contacts of the auxiliary contact pairs connected with them are arranged on an insulating bridge, whereas the other contacts of the auxiliary contact pairs are on a conducting bridge, which contacts are brought into engagement with the former by the bridges being moved against one another by a stop in the switch which limits the upward motion of the conducting bridge. The extinguishing chambers 1 may be of the differential-piston type and contain contacts which co-operate with movable conducts 2 which are mounted on the insulating bridge 3 and connected to contacts 5. The co-operating contacts 7 are mounted on a conducting bridge 6 which is guided by pins 9 on the bridge 3 and spaced therefrom by springs 8. The bridge 3 is operated by a rod 4 carrying a piston 11, working in a cylinder 10 on the bridge 6. In closing, bridge 3 is raised to bring contacts 2 into engagement while springs 8 maintain the bridges at a distance until 6 engages stops 12, whereupon bridge 3 continues its upward movement to close 5, 7 and also raises piston 11 in the cylinder 10. The electrodynamic forces on bridge 6 assist the springiness of the contacts 5, 7 to reinforce the contact between them. In opening, the bridges 3, 6 move together due to the action of a non-return valve in the piston 11 and cylinder 10, thus ensuring that the arc is set up in the chambers 1. In Fig. 2, the conducting bridge 6 is spaced from the insulating bridge 3 by springs 18 around rods 19 which pass through the bridge 3 and carry a member 16 serving with valve 17 to close the hollow piston 15. The cylinder 14 is secured to bridge 3 and the stop is provided by an insulating guide 20 for the rod 4.

Title: Pantothenic acid and similar growth-promoting substances
IPC: C07C233/46
Filed: 1940-03-27
Abstract: 535,988. Peptides of # - alanine ; lactones. MERCK & CO., Inc. March 27,1940, No. 5484. Convention date, April 3, 1939. [Class 2 (iii)] Pantothenic acid and similar peptides of #-alanine, which are growth promoting-substances, are made by reacting #-alanine or a salt or ester thereof with an α-keto-or α-hydroxyacid or with the corresponding lactone ; the product being hydrolyzed, if necessary, to produce the free acid. In examples (1) α-hydroxy- γ-n-valerolactone is reacted at 30‹C. with #-alanine ethyl ester and the product hydrolyzed with sodium carbonate solution, a compound of the formula is obtained, (2) α-hydroxy-#-methyl-γ-n-butyrolactone is similarly reacted with #-alanine ethyl ester, (3) the lactone obtained by hydrolysis with hydrochloric acid of the crude calcium salt of the pantotheric acid derived from sheep's liver by the process described by Williams and others (J. Am. C. S., vol 60, p. 2719) is similarly reacted with #-alanine ethyl ester. Other esters or salts of #-alanine may be used instead of the ethyl ester, and other lactones, e.g. α-keto-γ-valerolactone. Lactones :-α-Hydroxy-γ-n-valerolactone is made by treating aldol with hydrogen cyanide and hydrolyzing the nitrile obtained. α- hydroxy-#-methyl-γ-n-butyrolactone is made by condensing propionaldehyde with formaldehyde, converting into the nitrile and hydrolyzing. Other lactones of α-hydroxy acids may be obtained by a similar method, or they may be made from lactones containing one less carbon atom by reduction, addition of HCN and hydrolysis ; thus butyrolactone may be converted into α-hydroxy-#-hydroxy-valeric acid or the corresponding lactone. α-keto-lactones may be made from si mple lactones wi th one less carbon atom by treating with phosphorus pentachloride, and converting the acid chloride thereby formed into the nitrile of an α-keto chlorine-substituted acid by treating with cuprous cyanide ; the nitrile is then hydrolyzed and converted to the lactone by treatment with moist silver oxide. The α:-keto-lactones may also be made by condensing the simple lactones with di-ethyloxalate and de-carboxylating the product.

Abstract: 1,070,673. Valves. PARKER HANNIFIN CORPORATION. Feb. 8, 1965, No. 5484/65. Heading F2V. [Also in Division G1] In a liquid level control device fluid under pressure is supplied to a passage 3, Fig. 1, and some of fluid passes through openings 10 to a chamber 11 and through a pipe 24, Fig. 2 to a nozzle 20, Fig. 3 (not shown), from which a jet stream impinges on the opened end of a receiver 23 to transform the velocity head of the jet into a pressure head which is transmitted to a chamber 25 between diaphragms 16, 17. The pressure in chamber 25 deflects diaphragm 17 against pressure transmitted to a chamber 27 from chamber 11 through a pipe 28 whereupon the pressure on the valve 6 forces the valve 6 to leave its sealing to permit fluid flow through passage 3. The device is located in the tank to which the fluid is supplied and when the liquid reaches a level to cover the end of a pipe 31 and a bell 21 liquid is drawn up the pipe 31 to fill the bell 21 and hence stop the fluid flow from nozzle 20 thus decreasing pressure in chamber 25 and enabling valve 6 to close.

Title: Improvements relating to steam driven locomotives
IPC: F01K15/02
Filed: 1926-02-26
Abstract: 250,545. Boltshauser, H. April 8, 1925, [Convention date]. Railway locomotives, steam-turbine. - Comprises a locomotive of the kind having a reciprocating engine on the boiler vehicle and a turbine on the tender driven by the exhaust steam of the reciprocating engine, and in which a device in the conduit between the engine and the turbine automatically closes the conduit when the pressure therein falls below a certain value. According to the present invention the turbine comprises separate forward and reversing turbines VT, RT, and the automatic device. 32 is combined with and controls a reversing, valve 15, 16 admitting steam to one or other of the turbines according to the setting of a hand-controlled valve 35. The conduit 13 leading from the reciprocating engine (not shown) admits steam to one of the turbines when one of the valves 15, 16 is open. A pipe 17 leads from the conduit 13 to the valve 35 and when this is operated steam is admitted to one side of spring-controlled piston 32. The piston is connected by a lever 25 to a valve 27 controlling the admission of pressure fluid from a pipe 30 to a cylinder 22 having ,a piston 21 which raises and lowers the valves 15, 16, so that these are operated in accordance with the movement of the valve 35. When the piston 21 is raised both valves are lifted by means of stops 40, 18 on the rod 20 but the ports 18 on the valve 15 do not open the passage, to the turbine VT; when the piston is lowered, valve 16 is unaffected and valve 15 only is moved to an open position. When the pressure in the conduit 13 falls below a predetermined value the piston 32 is moved to its central position by its springs thus causing the valve 15, 16 to be closed and preventing the cylinders of the reciprocating engine from being subjected to a vacuum. The turbines exhaust into a condenser 11 the cooling water for which is cooled in an air cooler (not shown). The valve 35 may be operated by the reversing lever of the reciprocating engine.

Abstract: 814,043. Batteries. UNION CARBIDE CORPORATION. Feb. 19, 1957 [Feb. 20, 1956], No. 5539/57. Class 53. In order to interrupt the current from a dry cell if electrolyte exudes from the cell a part of the circuit is made of a conducting material which is attacked and destroyed chemically or electrochemically by the exuded electrolyte whereby the circuit is broken. Fig. 2 shows diagrammatically a cell in which a thin strip 30 of zinc or aluminium is placed in series with the load and in such a position that it is brought in. to contact with any electrolyte that escapes from the cell. The strip 30 is then destroyed by chemical action. If the strip is inserted between the load and the positive electrode 24 the strip is destroyed by electrochemical action. The positions of the positive and negative electrodes may be interchanged, the positive electrode forming the outer cup of the cell and having a terminal at its lower end. Fig. 5 shows the upper end of a dry cell having a metal member 66 which connects the carbon electrode 68 to the terminal cap 70 and which is surrounded by an insulating cylinder 77 supported on a waxed paper washer 75. Any electrolyte that exudes from the cell passes through openings in a second washer 76 and in the washer 75 and into the cylinder 77 where it attacks the member 66 and interrupts the circuit. Mercuric chloride and salts of aluminium 80 that are soluble in the exuded electrolyte may be enclosed in the cylinder 77 to hasten the disruption of the member 66. Fig. 6 shows a modification in which the attackable member 86 in the form of a strip connecting the carbon electrode to the terminal of the cell is pressed by a spring 85 which assists the breaking of member 86 when attacked by electrolyte exuding through opening 91b. Fig. 8 shows a further modification in which the attackable member 96 connects the bottom of the negative electrode 95 with the metal closure member 97. An insulating disc 98 separates the arms of the member 96 which may be made of magnesium. In a cell in which the zinc electrode is within the carbon electrode which forms the outer cylindrical jacket a spring-pressed attackable strip may be used to connect the carbon electrode to the top metal terminal closure.
