Title: Process for the preparation and preservation of vitamin-containing foods
IPC: A23L19/00
Filed: 1936-02-21
Abstract: A powdered food is prepared by reducing ripe bananas to a paste which is mixed with cooked chestnut and, if desired, fresh milk, flours of cereals or cereal biscuits or mashed leguminous plants or fruits, and desiccated under vacuum at not above 40-45 DEG  C., reduced to powder and packed in tins or other receptacles which are subjected to high vacuum to remove air, filled with nitrogen or other inert gas under pressure and hermetically sealed.  The powder before packing may be treated with ultra-violet rays to increase its vitamin content.  The receptables after filling are closed with the exception of a small aperture and are subjected to the vacuum treatment in an enclosure to which inert gas is subsequently supplied until a pressure slightly above atmospheric is reached.  The receptacles are then withdrawn and sealed, by soldering &c. as quickly as possible.  The Specification as open to inspection under Sect. 91 comprises also the preservation of any vitamin-containing alimentary substances which may be mixed with other substances, and which are prepared cold and introduced into receptables which are subjected to high vacuum to eliminate air, and then filled with inert gas and sealed.  This subject-matter does not appear in the Specification as accepted.

Filed: 1942-04-22
Abstract: 567,877. Electric heating. STEVENS, A. H. (Hoey, W. B., and McCurdy, E. D. [Representatives of Shaw, C. D.]). April 22, 1942, No. 54:11. [Class 39 (iii)] [Also in Group V] Thermosetting or thermoplastic material is injected at great speed from the cylinder into the mould through a nozzle which is heated while the material is passing therethrough, but is cooled when the mould has been filled. The nozzle is heated at a rate which is greater than the rate of heating of the mass in the cylinder and which, if applied to thermosetting material for a substantial length of time, would result in irreversible hardening of the material. Figs. 1 and 5 show an arrangement in which the nozzle 12 is electrically heated by two electrode elements 50 clamped thereon, each electrode element comprising a copper block connected by cables 51 to a, transformer 52. Each block is continuously cooled by water passing through a, passage 60. Just after the (water-cooled) plunger 5 begins its ejecting stroke, switch mechanism 70 cuts in the transformer, and during the stroke the nozzle is heated. As the stroke ends, the switch cuts out the transformer, which is not cut in again as the plunger recedes. Fig. 8 shows an arrangement in which a water-cooling jacket 64 surrounds the nozzle and an induction coil 66 surrounds the jacket. As the movable platen 24, carrying the moulded article or articles recedes to the right, springs 36 are compressed against the end of the platenmoving cylinder 25, and the moulded articles, carried on an undercut rod, are ejected. Material is continuously fed into the cylinder, from a hopper 2 and continuously ejected therefrom.

Title: Improvements in or relating to the refining of fatty oils and fats
IPC: C11B3/06
Filed: 1953-03-02
Abstract: In the refining of fatty oils with alkali lye and separation of the resulting soapstock from the refined oil, phosphoric acid is added to the crude oil and reacted therewith to form addition compounds prior to the mixture of the alkali lye with the oil. The phosphoric acid reacts with the phosphatides to form addition compounds which then react with the lye to form deemulsifying agents and thus prevent the entrainment of neutral oil in the soapstock.  The phosphoric acid is added to the oil in an amount, on a full-strength basis, of about 0.1 per cent to 0.4 per cent by weight of the crude oil.  The alkali lye is added in an amount approximating the theoretical amount required to neutralize the free fatty acids and preferably in an amount 0.1 to 0.5 per cent in excess of the theoretical amount.  The mixture of oil and soapstock is heated to an emulsion-breaking temperature, usually 60 DEG  to 80 DEG  C., and fed to a centrifugal separator.  Detailed examples are given of the treatment of cocoanut oil, peanut oil and cottonseed oil.  Specification 661,703 is referred to.

Title: Improvements in or relating to electrical circuit arrangements for the generation ofoscillations
IPC: H03K4/43
Filed: 1947-02-28
Abstract: 633,366. Sawtooth generating circuits. NEWMAN, E. A. Feb. 28, 1947, No. 5777. [Class 40 (vi)] A sawtooth generator comprises an amplifier which has its gain reduced during the forward stroke of the sawtooth waveform and increased during the flyback period, so that the flyback time is considerably reduced. In the Figure, capacitor 1 is charged from a negative supply source via resistors 2 and 23 and discharged via diode 3 to generate a sawtooth voltage across capacitor 1, the repetition frequency being controlled by impulses at 4 which periodically render diode 3 conducting. The sawtooth voltage is amplified in the D.C. coupled amplifier stages 5, 7, 12 to feed the deflecting coils 16 via output transformer 17, 19, the linearity of the forward stroke being improved by negative feedback via resistor 23. During the forward stroke of the sawtooth waveform the voltage at the control grid of valve 12 is falling, diode 20 conducts and reduces the stage gain by negative feedback via capacitor 21. At the end of the forward stroke diode 20 is cut-off and the amplifier gain rises to such an extent that the amplifier becomes unstable and " rings " at its natural frequency during the flyback period. At the end of a half cycle of " ringing," capacitor 1 commences to re-charge, diode 20 conducts and the oscillator becomes stable again.
