Title: Method of treating milk to obtain a product of reduced curd tension
IPC: A23C9/15
Filed: 1937-11-20
Abstract: 509,924. Milk preparations. SUBMARINE SIGNAL CO (LONDON), Ltd. (Submarine Signal Co.). Nov. 20, 1937, No. 31994. [Class 49] Milk is treated to give a product of reduced curd tension by separating all but a small quantity of the butter fat from the milk, e.g. by allowing to stand at 38-42‹ F. for 3 or 4 hours, passing the greater portion of the separated milk containing only a small amount of the cream through a pressure homogenizer a.t a high pressure, e.g. about 2000 1bs. per sq. in., passing the separated cream and the remainder of the separated milk through a pressure homogenizer at a low pressure, e.g. about 500 lbs. per sq. in., and mixing the two homogenized portions. The cream may be separated completely from the milk, cream to the amount of about one half per cent by weight of the whole milk being then mixed with the greater part of the skimmed milk and the mixture homogenized at high pressure, the remaining cream with the remaining skim milk may then be passed through the homogenizer at low pressure and the two portions subsequently mixed.

Abstract: 228,312. Saunders, A. G. Dec. 21, 1923. Die-rolling; tapering by rolling. - Metal strips or articles of irregular or non-continuous section are rolled from a bar by a process wherein the corners or edges of the bar over the lengths which will form the parts of smaller section are flattened or chamfered before passing through the rolls, thus avoiding the formation of the fins which are usually caused by the increased rolling pressure when the smaller section of the article is being rolled. In a mill for rolling wheel spokes, the lower roll b is provided with side flanges to guide the work and the upper roll has a projection c of the same length as the spoke to be produced. The upper roll is further provided with a cam surface d engaging a roller on a bell-crank lever f whose other arm is arranged to operate through adjustable studs k, a spring-pressed slide l carrying a roller n having chamfering surfaces n<2>. The bar is guided to the mill by rollers r, s and is sup ported while passing the chamfering roll by an idle roll q. For commencing the operation the bar may be chamfered by hand or mechanically.

Abstract: 864,837. Transistors. WESTINGHOUSE ELECTRIC CORPORATION. Oct. 23, 1957, No. 33081/57. Class 37. In a junction transistor comprising a semiconductor wafer 0.2 to 0.63 mm. thick provided with a flat-bottomed depression uniformly spaced 0.005 to 0.15 mm. from the opposite surface of the wafer and surrounded by a thicker portion, the emitter comprises an evaporated doping layer fused to the bottom of the depression to form a PN junction and overlain by an outer evaporated layer of a readily solderable metal and an intermediate evaporated layer consisting of said metal and the doping material, the base electrode comprises contact metal fused to the surround of the depression, and the collector electrode, forming a PN junction extending over a greater area than the emitter, is formed by alloying a doping member to the opposite surface. Such a transistor may be made in the jig shown in Fig. 4 comprising refractory members 438, 430 e.g. of graphite or molybdenum. A perforated acceptor foil 436 is located in a shallow recess 434 beneath grooved N-type germanium wafer 410 and the assembly placed in an evaporation chamber similar to that described in Specification 864,838. After raising the assembly above the germaniumaluminium eutectic temperature aluminium is evaporated through the aperture in member 438, and is subsequently alloyed to the bottom of the groove to form the emitter PN junction by raising the temperature further for a short time. During this heating perforated foil 436 also alloys with the wafer to form the collector PN junction, though as an alternative this may be formed in a preliminary step. After replacing jig member 438 by a member with a slightly smaller aperture further aluminium is evaporated on while the temperature is lowered from above to below the eutectic temperature. A transition layer of silver and aluminium and an outer layer of silver are subsequently evaporated on the aluminium layer. A base electrode in the form of a solder layer or a molybdenum or tungsten plate coated with nickel or silver is then applied to the groove surround, and emitter and collector contacts soldered to their responsive electrodes to complete the device shown in Fig. 5. Alternatively the collector is soldered to a nickel or silver-coated tungsten or molybdenum heat sink. If a wafer with a plurality of grooves is used separate individually or commonly connected PN emitter junctions may be provided in each groove associated with a common or individual collector PN junctions. A plurality of individually or commonly connected base contacts are provided in this arrangement. In the above devices acceptor activators other than aluminium may be used with wafers of N-type silicon, germanium, silicon-germanium alloys, aluminium phosphide, aluminium antimonide, gallium phosphide, gallium arsenide, indium phosphide, and indium antimonide. Alternatively donor activators may be used with P-type wafers. Suitable readily solderable metals are silver, lead, tin, zinc and alloys of two or more thereof.
