Title: Composition and method for coating foodstuffs and articles thereby obtained
IPC: A23L1/00
Filed: 1958-04-24
Abstract: Articles of food, e.g. cuts of meat, liver, poultry, fish, bacon and luncheon meats, are provided with tough, transparent, tightly-adherent but readily strippable coatings by applying to the article a molten composition containing 19-70% of an ethyl cellulose which has an ethoxyl content of 47.5-50% and is, in a 5% solution in an 80 vol. toluene-20 vol. ethanol mixture, of viscosity 6-200 cp., 15-65% of a refined mineral oil of Saybolt viscosity 80-400 units at 100 DEG  F., and 5-30% of a colourless, odourless, non-toxic plasticizer which is a solvent for the ethyl cellulose, and cooling the applied composition to harden it. Cooling of the applied composition may be effected by coating a frozen food article.  The plasticizer is exemplified by an alkyl phthalyl alkyl glycolate, e.g. butyl phthalyl butyl glycolate, a trialkyl ester of acyl citric acid, e.g. acetyl tributyl citrate, a dialkyl adipate, an acetylated mono-or di-fatty acid glyceride, a dialkyl phthalate, e.g. di-2-ethylhexyl phthalate, glyceryl monostearate or monoleate, n-butyl stearate, an alkyl-aryl phosphate, and a refined, deodourized castor oil.  The composition may contain up to 20% of an epoxidized glyceride of an unsaturated fatty acid of 12-22 carbon atoms to inhibit hydrolytic degradation of the ethyl cellulose, an antioxidant such as butylated hydroxyanisole, nordihydroguaiaretic acid or 2,6-ditertiary butyl 4-methyl phenol to inhibit oxidative deterioration of the ethyl cellulose, and citric acid, tartaric acid, tricresyl phosphite or a mixture of organic phosphite-epoxy compounds to maintain clarity in the coating.

Abstract: 864,120. Semi-conductor devices. SIEMENSSCHUCKERTWERKE A.G. April 25, 1957 [April 26, 1956], No. 13293/57. Class 37. In a semi-conductor device comprising a monocrystalline semi-conductor wafer with a first electrode and an associated PN junction extending over one face, and an electrode arrangement on the opposite face, the shortest distance of the edge of the first electrode from the outermost edge of said electrode arrangement being more than ten times larger than the wafer thickness. In one embodiment a PN junction device is made by assembling in superposed relationship a molybdenum or tungsten base-plate 5, a foil 4 of gold doped with 1% antimony, a wafer 2 of monocrystalline P-type silicon, and an aluminium foil 3, embedding the assembly in an inert material such as powdered graphite or magnesium and heating to fuse the parts together to form the device illustrated in the left-hand half of Fig. 1. On account of the geometry of the arrangement any short-circuit across the exposed edge of the PN junction (shown as a dotted line) is in series with a highresistance path to the edge of the ohmic electrode 3. This resistance may be further increased by reducing the thickness of the wafer beyond electrode 3 by grinding or corrosion and by making the wafer of high resistivity material. In a modification the gold electrode extends over the edges of the wafer to form a thin peripheral ring on the upper surface thereof. The device may be cooled by forming plate 5 with cooling fins or with ducts for fluid coolants, or by fixing the plate to a copper block of high heat capacity. A further embodiment consists of a transistor (Fig. 3) in which the junctionforming electrode 4 serves as collector. The emitter electrode 6 is in the form of an annulus which is disposed between and concentric with a circular electrode 3a and annular electrode 3b which are connected together to form the base electrode. Specification 864,121 is referred to.

Title: Improvements in egg boilers
IPC: A47J29/04
Filed: 1928-05-09
Abstract: 296,773. Cavilla, R. J. Sept. 8, 1927. [Convention date]. Controlling travel for a fixed distance. - In an egg boiler, the eggs are contained in a. basket, or baskets, 27 connected by flexible means, e.g. a chain, to a connterweight 31 which is lowered in a controlled manner, e.g. by a motor, chain and screw gearing; causing the basket to be lifted from the water, and means are provided for releasing the apparatus controlling the weight, whereby the basket may be lifted from the water at any time before the previously set time. The water is contained in a tank 13, and, as shown, two baskets 27 are used. Each basket is connected by a bail handle 26, rod 23 and crossbar 22 to two chains 21 trained over pulleys 20, 28 and secured to the weight 31 which moves vertically in a casing 17. Half-nut sections 34, Fig 7, are slidable in a groove on the under-side of the weight, and are normally pressed towards one another by springs 35 which abut against the side portions 32 of the weight. The nut sections 34 engage the threaded upper part of a shaft 38, rotated by the motor through chain and sprocket reduction gearing and worm-gearing 39, 58. The threads are formed with horizontal upper faces and sloping under faces, so that, when the basket 27 is pulled down, the weight rises on the shaft 38, this being permitted by the nut sections riding over the threads. The upward movement of the weight is limited, and the cooking time is consequently varied, by a notched member 70 slidable in the cap 18 of the casing 17 and pressed by a leaf spring into engagement with a retaining lug 73. The bottom of the member 70 carries a set screw 75 with which the top of the weight contacts when it is moved upwards. The weight is released from the screw shaft 38, if it is desired to curtail the cooking period, by a rack bar 54, slidable in the walls of the casing 17, and engaging a pinion 53 on a shaft 48 which carries a cam 52 disposed between pins 36 projecting from the nut sections. When the knob 56 is pressed against the action of the spring 55, the shaft 48 is rotated and the cam 52 thereon separates the half nuts and allows the weight to fall and lift the basket 27 from the water. A buffer spring 47 for the weight is provided. The weight during its descent breaks the electric circuit, this being effected by a projection 92 on the weight contacting with an arm 86 on a member pivoted at 84, the knife portion 87 thereby being withdrawn from the spring contacts 88, 89. A stop 90 limits the angular movement. When the weight is raised, the knife 87 is re-engaged with the contacts 88, 89 by the projection 92 engaging an arm 85. The electrical arrangements are such that the motor works as long as one basket 27 is in the cooking position.
