Patent GB-614720-A (GB)
Title: Improvements in and relating to electric filter circuits
IPC: H03H7/01
Filed: 1946-07-22
Abstract: 614,720. Impedance networks. GENERAL ELECTRIC CO., Ltd., and LEVY, M. M. July 22, 1946, No. 21825. [Class 40 (viii)] A filter network has a bridging network connected between points thereon, the difference between the time delay along the filter network between the points and that along the bridging network being substantially equal to the periodic time or an integral multiple of the damped oscillation generated at the output terminals of the network in response to a short pulse applied to the input terminals of the network. The result of this is to superimpose an advanced and delayed train of oscillations on the parent oscillation and permits, among other things, of making the output oscillation, from a short pulse, symmetrical. This is a condition that renders the phase frequency characteristic of the filter linear. Another use of the method of the invention is in producing a distortion correcting network. More than one bridging network can be used involving various multiples of the periodic time. In the example shown, the terminals of the filter are T1 and T2 and two bridging arrangements, consisting simply of condensers C3 and C4, are used. In this case, the filter sections are prolonged beyond the output terminal so as to delay both of the components introduced by each bridge. The lumped impedance circuits shown may be replaced by coaxial lines.

Title: Improvements in or relating to the production of articles for the preparation of beverages and foods
IPC: A23L27/00
Filed: 1951-09-19
Abstract: Open-sided containers of fondant, e.g. a mixture of 4 1/2 -8 parts of cane or beet sugar and 1 part of the liquid glucose known as corn syrup, are made by depositing the fondant in an open mould, placing in position, while the fondant is corporating a mandrel of the shape of the hollow to be formed, holding the mandrel in position, by passing the mould and mandrel under a series of rollers, until the fondant has been set, and then withdrawing the mandrel.  A plurality of containers may be made from a block of partly solidified fondant by forming a plurality of depressions in the block, the block being subsequently cut into sections.  Alternatively, a mass of melted fondant may be deposited in a flexible mould of box form incorporating a mandrel of the shape of the hollow to be formed, and, after solidification of the fondant, the sides of the mould may be flexed to allow removal of the container, which is then inverted to present the hollow uppermost.ALSO:In making articles for the preparation of sugar-containing foods, exemplified by table jellies, fruit squashes and sweetened coffee, open-sided containers are made from a composition containing fondant, flavouring matter is placed within these containers, and the open sides are closed by a composition containing fondant.  The fondant is a mixture of cane or beet sugar and glucose, e.g. a mixture of 4 1/2 -8 parts of sugar with 1 part of the liquid, acid-hydrolyzed starch product known as corn syrup or commercial glucose; it has properties which permit melting and moulding, retention of moulded shape and hard setting after cooling, easy uniting with further fondant, and impermeability to air.  When articles for the preparation of table jellies are to be made, the hollows in the containers are filled with powdered gelatine and a gelatine capsule of flavouring matter is located within the powdered gelatine; the jelly is made by stirring the article with boiling water until dissolved.  In making an article for the preparation of a fruit squash, the filling comprises a concentrate of fruit juice, e.g. is a filling of orange juice concentrate with citric acid, other flavouring material, colouring material, an alginate and an aqueous solution of sulphur dioxide or sodium metabisulphite.  Alcoholic beverages, coffee, cocoa and soup concentrates, tomato juice, mint sauce or jelly and horseradish sauce or cream are also referred to as fillings.
Patent GB-653798-A (GB)
Title: Improvements in mixed allyl ethers of starch
IPC: C08B31/08
Filed: 1947-08-08
Abstract: Solutions of mixed allyl starch ethers (for preparation see Group IV (b)), in organic solvents such as aliphatic hydrocarbons, e.g. gasoline, petroleum ether and kerosene leave a film which polymerizes after setting at room or elevated temperatures particularly in the presence of catalysts, e.g. cobalt naphthenate, and is then insoluble in organic solvents.ALSO:Mixed allyl starch ethers containing substantially no free hydroxyl groups and which are soluble in organic solvents such as aliphatic hydrocarbons, e.g. gasoline, pet. ether and kerosene, are made by partially etherifying starch by heating in the presence of aqueous caustic alkali with an alkyl, aralkyl or alkenyl halide other than allyl halide, and substantially etherifying the product by heating in the presence of aqueous caustic alkali with an allyl halide.  Ether groups specified other than allyloxy are methoxy, ethoxy, propoxy, butoxy, pentoxy, hexoxy, lauroxy, vinyloxy, crotyloxy, isocrotyloxy, oxybenzyl and oxycinnamyl.  The following starch ethers may be prepared: butyl-allyl containing 1.5 butyl and 1.5 allyl groups per glucose p unit, hexyl-allyl containing 1.0 hexyl and 2.0 allyl groups per glucose unit and lauryl-allyl containing 0.8 lauryl and 2.2 allyl groups per glucose unit.  Heptyl allyl starch ether is made by heating starch in aqueous caustic soda for half-an-hour at 65 DEG C., reacting with heptyl iodide in the presence of additional caustic soda at 95 DEG  C. for 1 hour, 105 DEG  C. for 2 hours and 118 DEG C. for 3 hours when the mixture is cooled and neutralized with 50 per cent acetic acid, the precipitate containing 1.7 heptyl units collected and dried at 40 DEG  C. is reacted with allyl bromide in M.E.K. and aqueous caustic soda and the resultant mixed ether isolated. Alternatively the partly alkylated starch need not be isolated before allylation a butyl allyl ether containing 1.4 allyl groups and 1.6 butyl groups per glucose unit being made in this manner.

Title: Improvements in code translators for automatic telephone systems
IPC: H04Q3/00
Filed: 1960-06-24
Abstract: 881,618. Automatic-exchange systems. TESLA, NARODNI PODNIK. June 24, 1960 [June 30, 1959], No. 22211/60. Class 40 (4). In a code translator in which relays such as A . . . E each correspond to one code, the sets of terminals 1 . . . 10 marked by the three code digits are connected to provide energizing and holding circuits for the relays so that when all the digits are received only one relay remains energized. The terminals may be marked as shown, by switch wipers dx, dy, dz stepped by the successive digits or by contacts of counting relays. Assuming, for example, that the code 235 is received, relays A, B, C energize in position 2 of the digit distributer. In position 3, A, B hold over hl while C holds over h2 in series with RX which releases the seizing relay F. In position 4, A holds over hl while B holds over h2 in series with RY which releases C and RX. In position 5, A holds over h2 in series with RZ which releases B and RY. Finally, terminal ur is earthed to determine further operations. Relays MY, MZ (not shown) provide for the use of 1-digit and 2-digit codes. If the translator is seized after only two digits are stored in the register, MZ is operative, and if after only one digit, both MY and MZ are operative, and the control circuits are modified accordingly. The receipt of one or two digits of a 3-digit code then results in the operation of relay N which earths terminal ni to indicate an insufficient number of digits. If relay F fails to release, terminal nk is eventually earthed to indicate that the code received is not one that is provided for. A modified arrangement is described, Fig. 4 (not shown). Instead of additional holding windings, relays A . . . E may be provided with holding circuits including rectifiers.
