IPC: A23L15/00
Filed: 1926-07-19
Abstract: 279,159. Epstein, A. K. July 19, 1926. Condiments; preserving liquid egg.-To enable liquid egg material, more especially egg yolk, to be frozen without impairing its emulsifying properties, an edible water-soluble organic hydroxyl compound capable of preventing denaturing of egg protein during freezing and an edible acid capable of increasing the waterimbibing capacity of the protein are added. The hydroxyl compounds used include glycerine, ethyl alcohol, ethylene glycol, sucrose, lactose, and dextrose. The acid employed may be acetic, tartaric, citric, lactic, malic, succinic or phosphoric. In an example, glycerine and citric acid are mixed with yolk and the product frozen solid in cans. a suitable temperature being -10‹ to - 12‹ F., and kept solid until required. When the egg material is to be used in salad dressings nr mayonnaise products as an emulsifying agent with vegetable oils, vinegar, spices, condiments &c., a small amount of natural or synthetic mustard oil, oil of capsicum, or other essential oil having preservative and condimental properties may be added to prevent decomposition during thawing. The mustard oil may first be dissolved in a larger quantity of melted glacial acetic acid, monoacetin or other edible ester, ethylene glycol or other suitable solvent, which is then mixed with the other ingredients, e.g. glycerine or ethylene glycol, to secure uniform dispersion of the oil in the egg product. In an example, powdered paprika (Capsicum Annum) is added to glacial acetic acid which is preferably heated. After filtering, a small amount of mustard oil is added to the filtrate. which contains the condimental ingredients and red colouring matter from the paprika, and it is then mixed with glycerine before addition to the egg yolk.

Title: Improvements in compression rolling polyolefin film
IPC: C08J7/043
Filed: 1961-05-19
Abstract: 982,912. Producing poly-alpha-olefine film. KODAK Ltd. May 19, 1961 [May 19, 1960], No. 18353/61. Drawings to Specification. Heading B5B. A poly-alpha-olefine film is produced by heating the poly-alpha-olefine to form a clear melt, forming a sheet therefrom 2 to 10 times the desired thickness of the final film, and obtaining the final film from the sheet by passing the sheet between rollers under sufficient pressure to reduce the thickness of the sheet to the desired final thickness, the surface of the film at the line of pressure being covered by a lubricant containing an additive. The additive may be a stabilizer such as an antioxidant, an inhibitor, a slip agent, an antiblocking agent, or a moisture-proofing agent. The preferred polyalpha-olefines are polyethylene and polypropylene. The term " lubricant " is defined as water or any conventional lubricating oil, lubricating grease or a solid lubricant, such as sodium stearate or graphite, or any other normally liquid or greaslike organic substance or solid organic or inorganic substance which has no deleterious effect on the polyolefines or the processing equipment at the rolling temperatures employed and which has the ability at the rolling temperature of reducing the friction between the roll and the polyolefine sheet, as indicated by a marked increase in percentage elongation of the sheet at a given roll pressure and rolling temperature as compared with rolling under the same conditions without a lubricant. If water is employed, it is desirable to add a wetting agent thereto. In the examples, methanol is used as the lubricant for polyethylene sheet and ethylene glycol as the lubricant for polypropylene sheet. The polyolefine may first be melt-extruded to form a sheet having a thickness 4 to 60 times that desired in the final film, and the sheet then stretched in a direction perpendicular to the direction of extrusion to reduce the thickness of the sheet by 100 to 500% at 65 to 240 F. The sheet is then passed to the pressure rollers. The temperature of the pressure rollers is preferably within the range of 40 to 240 F. for polyethylene sheets and 40 to 285 F., preferably 100 to 270 F., for polypropylene sheets. The additive is incorporated in the lubricant, preferably in the form of a solution but may be incorporated in the form of an emulsion, or, when the additive is a finelydivided inorganic solid such as silica, aluminium hydroxide, talcum powder, ground glass, diatomaceous earth, or titanium dioxide, as a suspension. A long list of various types of additives which may be used is given. Specifications 964,321, 964,780, 980,260 and U.S.A. Specifications 2,861,053, 2,947,721, 2,972,596, 2,972,597, 2,976,260, 2,983,709, 3,000,856, and 3,003,996 are referred to.

Title: Improvements in and relating to pulse generating systems
IPC: H03K3/86
Filed: 1943-11-08
Abstract: 582,850. Impulse generators; sparkgaps. BRITISH THOMSON-HOUSTON CO., Ltd. (General Electric Co.). Nov. 8, 1943, No. 18561. [Classes 39 (i) and 40 (v)] In a pulse generating apparatus in which a capacitive device is charged and subsequently discharged through a load, two spark-gaps are provided and connected in series with the capacitive device and load, and means are provided for producing the discharge by suddenly changing the apportionment of the voltage between the gaps. Fig. 1 shows a system in which the capacitive device 1 is constituted by a section of transmission line such that the discharge produces a rectangular wave form. The voltage impressed on the spark-gaps 14 and 15 is apportioned by the resisters 16 and 17, a condenser 18 being provided, if necessary, to balance the distributed capacity. The spark-gap is triggered by the application of a positive pulse to a valve 19 in shunt to the gap 15 to energize the load 6, as shown, feeding magnetron 7. Triggering is initiated by a gas-filled tube 29 synchronized from the A.C. source and arranged to operate a sweep circuit which supplies a negative pulse to a multi-vibrator 31. The phase is adjustable by regulating the cathode bias applied to the tube 29 and the output of the multivibrator is applied to render the valve 26 conductive and so in conjunction with the inductance 24 to produce positive pulses at the grid 23 on the termination of the pulse. As shown, charging is effected from an A.C. supply through a rectifier 3 and inductance 4. Alternatively, a D.C. supply may be used, Fig. 4 (not shown), a condenser may be arranged in series in the charging circuit which includes an inductance and a switch interconnected with the switch in the supply to the valve fed from the multivibrator. The circuit constants may be such that the charging time representing a half period of oscillation is less than the pulse interval. In this case, the capacitive device is charged to twice the voltage of the source. Alternatively, the charging period may be greater than the pulse interval. In this case the rectifier is unnecessary and the larger the value of the series inductance the more nearer linear is the rise in voltage. In a further modification, Fig. 5 (not shown), instead of reducing the potential on the intermediate spark-gap member, a pulse of high voltage is applied to that member to -effect triggering. Fig. 2 shows the spark-gap construction. The electrodes 49 and 50 are hollow and connect with air ducts 38 and 39 so that an air blast is provided in the gaps which consist of the electrode 49 and a boss or plate 51 or 52 of tungsten. As shown, the gaps are of solid material, but, alternatively, may be hollow and of spun or pressed sheet material. In order to prevent undesired sparking due to rust, the surfaces may be plated with gold or silver. The reliability of firing may be increased by irradiating the gaps from a source of ultraviolet light such as a quartz mercury lamp.
