Title: Manufacture and Packaging of Cooking Fats
IPC: A21D2/16
Filed: 1967-03-03
Abstract: Cooking fat used in confectionery processes where it is usual to cut portions from a block, is formed into a rod which is coated with a material preventing adhesion e.g. hard fat, edible protein or carbohydrate, the rod being cut to ready use portions and packed in a bag &c. Methods of preparing and extruding various fats are described the adhesion preventing material being showered on the rod as it leaves the extruder and is cut by a reciprocating wire. The cut lengths fall on a screen conveyer where excess coating falls away. Alternatively an air blast removes the excess. In one method of preparation of a pastry margarine, the emulsified fat at a temperature of 40 -50 C., is chilled by passing through an annular space between an outer chilled scraped metal surface and an inner surface, passed through a region where further crystallisation occurs and then is worked by passing it through fine orifices e.g. through screens. Alternatively chilling may be effected by feeding warm emulsion to a chilled rotary surface and scraping it off. The final outlet is a die plate through which the rods are extruded. The rods may be composite and have a matrix of flexible cooking fat with one or more cores of soft cooking fat, e.g. shortening, formed by extending the matrix through a main aperture surrounding die apertures for the cores.

Title: Oxidation of Soluble Sulfide Compounds
IPC: C01B17/64
Filed: 1967-11-09
Abstract: Solutions of soluble sulphide compounds are oxidized by contact with molecular oxygen in the presence of a solid catalyst comprising a sulphide of nickel, iron, or cobalt supported on a carrier. The solution may be an aqueous alkaline solution, in particular, an ammoniacal solution of hydrogen sulphide, and the carrier may be alumina or activated charcoal, or other porous material. (A list is given). The catalyst/carrier composite may contain up to 63 wt. per cent of catalyst, calculated as the sulphide. The process is carried out at 0 to 100 C. using 0À25 to 1 moles of oxygen per mole of sulphide if elemental sulphur is the desired porduct, and at 100 to 200 C. using more than 2 moles oxygen per mole of sulphide if the desired product is a highly oxidized solution consisting mainly of sulphate, but possibly containing thiosulphite, sulphite, or dithionate, which solution has a low biological oxygen demand so that it may be discharged into rivers. In each case the reaction is performed at a pressure such that the solution is maintained in the liquid phase, and in the former case the sulphur is recovered by filtration, centrifugation, or settling.

Title: Transistorized vertical deflection circuit
IPC: H04N3/16
Filed: 1971-05-14
Abstract: Transistorized vertical deflection circuit employs output stage of class B, push-pull, complementary symmetry configuration. Miller integration approach is used for sawtooth wave generation, with feedback waveform derived from yoke current sampling resistor. Diode, coupled between ground and base of the (NPN) output transistor which conducts during retrace and first half of scan, operates in Zener region during retrace to hold voltage at joined emitters of output pair at s substantially constant voltage during retrace output waveform is thereby stabilized against effects of B+ changes due to line voltage variations or loading extremes, and remaining (PNP) output transistor dissipation is held substantially constant in the face of such changes. Diode in feedback path, forward biased when retrace ends, ensures rapid turn-on of driver stage when discharge transistor cuts off oppositely poled diode in shunt with first feedback diode completes low impedance capacitor discharge path during retrace. One winding half of vertical deflection yoke is shunted by a capacitor of a value selected to introduce cancellation of horizontal frequency components across yoke/pincushion circuitry, in order to minimize feedback of interlace-disturbing horizontal components in deflection circuit.
