Patent GB-708160-A (GB)
Title: Improvements in or relating to vitamin-containing products
IPC: A61K31/59
Filed: 1952-05-08
Abstract: A vitamin A preparation in the form of beadlets is prepared by dispersing a crystalline form of vitamin A, preferably the acetate or other ester, in a solution containing gelatin, gum acacia, pectin; tragacanth &c., and a sugar-like material, e.g. molasses or honey, suspending the dispersion in an oil in the form of small beadlets, and chilling the oil suspension, say, to 10 DEG C, to gel the beadlets.  Suitable oils are corn oil, soyabean oil, cotton oil, sesame oil and mineral oil.  The aqueous suspension may be heated above the melting point of the vitamin, which crystallizes on cooling the oil suspension.  Particularly during the heating stage, the suspension should be blanketed with an inert gas, e.g. carbon dioxide or nitrogen.  Boiled (air-free) water should be used for preparing the suspension.  The separated beadlets are partially dehydrated by treatment with acetone, ethanol, dioxane, or isopropanol, which liquids may in addition be added to the cooled oil, and thereafter dried on trays at room temperature in a low humidity atmosphere. They are thereafter washed with acetone and air-dried.  In one example, the ingredients are mixed in a turbine-type homogenizer, and thereafter introduced into the oil in fine droplet form by being fed into a cylinder formed at its bottom with fine holes and rotating in the oil.  Specifications 490,001, 491,212 and 541,663 are referred to.

Title: Data processing device
IPC: G06F7/00
Filed: 1966-03-21
Abstract: 1,081,665. Data processors. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 21, 1966 [April 5, 1965], No. 12255/66. Heading G4A. In a data-processing device, a logical function of corresponding portions of two operands is formed and passed through first or second means to an output register, the first means providing the result of an arithmetic operation on the operands and the second performing an operation. Two operands are fed to a bit function generator which produces the AND, OR and OR-E (meaning exclusive-or) of each pair of corresponding bits. For addition, the output of a final sum adder is gated to an output register, the final sum adder being fed with half sums (being the OR-E signals), and carries from a carry look-ahead generator fed by the AND and OR signals. Subtraction is by one's or two's complement addition, involving the inversion of one of the operands before input to the bit function generator, and control of the carry look-ahead generator either to permit end-around carry or to add 1 to the lowest order bit position respectively. For shift, the set of bits to be shifted and a set of all zeroes are supplied as the two operands and the OR-E signals (equalling the bits to be shifted) are gated to the shifter from which (after shifting) they are gated to the output register. The results of the logical operations AND, OR, OR-E are passed to the output register via the shifter (without shifting) by passing to the shifter the AND, AND and OR-E, OR-E signals from the bit function generator respectively. It is mentioned that the shift function may be used in multiplication or division (but no details are given.

Abstract: 792,765. Delivering measured quantities of liquids. LEWIS, E. C., and ALUMASC, Ltd. Feb. 13, 1956, No. 12359/55. Class 106(5) A liquid dispenser comprises a measuring chamber 6 movable by means of a handle 11, a supply valve 20 fitted by means of a head 7 to a container 2 or other source of supply and an outlet valve 20<SP>1</SP> fitted at the bottom of the measuring chamber above an outlet orifice 41. When the handle is moved one way to raise the chamber, the supply valve 20 is opened by the abutment of a seating 50 with the hollow stem 23 of the valve and the outlet valve 20<SP>1</SP> is closed by a spring 27<SP>1</SP> as its hollow stem 23<SP>1</SP> moves away from, a seating 55 on the outlet orifice .41. On moving the handle the other way to lower the chamber and deliver its contents, the supply valve 20 is closed by its spring 27 and the pressure of the liquid and the outlet valve 20<SP>1</SP> is opened by abutment of its stem on the seating 55. In the intermediate position of the handle, the chamber assumes a position in which both valves are closed. The insulated container 2 is cooled bv a refrigerating coil 4 and the liquid is drawn from it through a stand pipe 14 in order to maintain a reserve of cooled liquid. The chamber 6 may be transparent and be filled to a level either indicated by graduations or determined by a float valve 12. The float may be guided by projections 56 or the bolts 36 that clamp end covers 34, 35 on the chamber may be provided inside the chamber for this purpose. The outlet orifice is provided on a cross-piece 60 removably fitted to pivoted links 59. Since the liquid is drawn from the bottom of the chamber and a vent 62 to atmosphere is provided, frothing is reduced but, particularly where the supply valve head 7 is connected to a source of supply 3 without the interposition of a container 2, frothing may be minimized by arranging the chamber 6 to connect through a valve similar to valve 9 with a vent to atmosnhere which preferably incorporates a pressure relief valve. The liquid pressure is thus reduced in two stages, firstly to that of the relief valve as the chamber fills and secondly to atmospheric pressure as the chamber is lowered and opened to atmosphere through the filling aperture 51.
