Patent GB-272274-A (GB)
Title: Improvements in and relating to processes of making starch products and dry starch products
IPC: C08B31/00
Filed: 1926-03-08
Abstract: 272,274. Stern, E. March 8, 1926. Starch.-Starch products are made by treating a starch compound such as alkaline starch with one or more metal compounds such as alkaline earth compounds, so that a metal-starch compound is precipitated, the precipitate being then treated with at least one, water soluble agent consisting of amionic and cathionic components, such as a salt, such that. by adding water, at least one of the components will form with the precipitated metal starch compound a water-soluble starch compound. In the preferred form, the remaining component of the agent forms a precipitate with the metal which formed part of the metal-starch compound. The metal-starch compounds are preferably compounds of barium, calcium, strontium, beryllium, magnesium, zinc, aluminium, iron and copper and may be double compounds such as barium-aluminium-starch. Suitable agents for converting the metal-starch into a water soluble compound are salts such as sodium sulphite, phosphate or carbonate, or potassium sulphate. An example of a reaction according to the invention may be indicated thus:- Alkaline starch + BaCl2 = Ba-starch + Alkaline chloride Ba-starch + Alkaline sulphate = Alkaline starch and BaSO4. The metal-starch compounds are preferably dried to deprive them of at least 25 per cent of their moisture, before adding the agent, and may be dried in an atmosphere of carbonic acid to produce a certain amount of insoluble carbonate in the mass. The agent may be added as a dry powder which will only react on addition of water, or in solution, when the reaction, occurs at once. Soap may be added to the reaction mixture. The precipitation of the metal-starch compound may be promoted by the addition of alcohol. When reaction with the agent occurs, a certain portion of the metal or metals' which were combined with the starch is precipitated as hydroxide &c., and the products may retain characteristics such as colour, disinfecting properties, e.g. copper starch, of the metal or its cations. An example describes the addition of alizarine or azo-dyes to a barium-aluminium-starch precipitate. On the addition of sodium sulphate, alkaline-starch, barium sulphate, aluminium hydroxide and precipitated dyestuff form a coloured product. Other examples of the process are given.

Title: Vending machine units
IPC: G07F5/22
Filed: 1971-04-09
Abstract: 1402541 Vending machine control unit NATIONAL REJECTORS (UNITED KING- DOM) Ltd and EMIHUS MICROCOMPONENTS Ltd 10 July 1972 [9 April 1971] 6404/71 Heading G4V A vending machine control unit comprises an integrated circuit totalizer 8 which receives outputs from a coin and/or banknote acceptor 5 to add the monetary value thus represented and compare the immediate total with a preset value. When the total reaches the present value the totalizer activates a vend output signal to permit a vend operation to occur. As shown, the totalizer 8 has 3 vend outputs 9 each corresponding to a commodity on sale, selection of which is made by closing a switch 1-3 which operates a vend unit 10. Change giving is controlled by a circuit 11 which is set by an adjustable diode matrix 13 so that particular money denominations are issued. Another adjustable diode matrix 12 is manually set to control the values at which the totalizer sends an output on lines 9 and a diode matrix 12a is set to select vending operation with or without change giving. Totalizer circuit.-The integrated circuit totalizer includes a parallel input to serial converter which gates output pulses from a clock generator to represent values of coins inserted (Fig. 2, not shown). These serial pulses are applied to three counters, representing different prices, each of five stages. The counters are thus counted down from their pre-set values and when a counter reaches zero an output is sent along one of the lines 9 and a vend operation may then be completed by closing a selection switch 1-3. The counters are then reset to their pre-set values. Change-giving circuit.-A vend output signal from the totalizer applies an input to the changegiving circuit 11, which is also an integrated circuit. Subsequent money unit pulses enter an over-value counter (45-47) (Fig. 4, not shown). When a vend switch 1-3 is closed a signal is gated so as to allow the count registered in the over-value counter to be transferred to a store (52), the counter then being reset. A change calculator (63) receives inputs from the store (52) and is conditioned to control change-giving in particular denominations from solenoid operated storage shoots. The store (52) is then reset by the calculator.
