Title: Improvements in the manufacture and production of condensation products
IPC: C09D167/00
Filed: 1928-12-10
Abstract: 327,722. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Dec. 10, 1928. Band.-Synthetic resins are prepared by reacting ether or thio-ether dicarboxylic acids or their anhydrides with polyhydric alcohols (including ether-alcohols such as polyglycols and polyglycerols containing at least two hydroxy groups) or esters of polyhydric alcohols with fatty acids, such as oleic, elaeostearic, or the acids of linseed or China-wood oil, or the hydroxy alkyl esters of higher fatty acids which may be obtained by the reaction of olefine oxides or halogen hydrins on the corresponding acids, the esters in all cases containing at least one free hydroxy group. The dicarboxylic acids mentioned are diglycollic, methyl-diglycollic, dihydracrylic, salicyl-acetic, thiodiglycollic, thiodilactylic, and 2-carboxyphenyl thioglycollic acids. A part of the dicarboxylic acid may be replaced by phthalic, succinic, adipic or like dicarboxylic acid. The reaction mixture may contain higher fatty acids such as oleic or elaeostearic acids or the acids of linseed or China wood oil. The reaction may be effected with exclusion of oxygen, for instance in a current of inert gas or in vacuo or under pressure and with or without condensing agents such as metals, metal oxides, acids, acid or alkaline substances, sodium acetate, and zinc chloride, and with or without diluents or solvents such as phthalic esters, butyl diglycollates, glycol diacetate natural or artificial resins such as colophony or phenolformaldehyde condensation products. The products are suitable for the production of lacquers, films, insulating materials and many other articles, and various additions, such as ketones, alcohols, acetic esters, softening agents such as phthalic or phosphoric aesters, oils such as linseed and China-wood oil, waxes, fillers, and colouring matters may be added, at any stage before the final hardening for stance during the condensation process. Asbestos, slate-meal, talc, mica, alumina, slag-powder, lime and gypsum are mentioned as suitable fillers. The products may be used as substitutes for marble, slate, and ceramic products, for brake bands, grinding tools, &c. Specification 328,190, [Class 2 (iii), Dyes, &c.], is referred to.
Patent GB-648001-A (GB)
Title: Improvements in or relating to a process for the production of emulsions, dispersions and solutions of methacrylic ester co-polymers
IPC: C08F220/12
Filed: 1946-12-10
Abstract: Dispersions, emulsions and solutions of methacrylic ester copolymers are prepared by copolymerizing monomeric methyl methacrylate with a monomeric alkali metal salt of methacrylic acid, the latter in an amount of from 8-98 per cent mol. proportion of the mixture, in an aqueous medium.  The salt is preferably prepared in situ by saponification of methyl methacrylate in aqueous emulsion containing, e.g. sodium lauryl sulphate, under conditions such that no polymerization occurs. The greater the amount of alkali metal methacrylate in the copolymer, the less the amount of emulsifying agent required. Polymerization is preferably effected with the aid of a catalyst, e.g. sodium persulphate and heat, e.g. temperatures of about 90 DEG  C., with stirring.  The copolymer emulsions may be plasticized by mixing while hot with emulsions of plasticizers such as dibutyl phthalate, methyl glycol phthalate, glyceryl monolactate triacetate and triethylene glycol dihexoate.  Glycerine may be used where the initial saponification is 50 per cent or more.  The products with about 10 per cent saponification of the monomeric ester are useful leather dressings.  Copolymers of sodium and methyl methacrylates in equal proportions and where the salt is in greater proportion are powerful emulsifying agents, e.g. for pearl polymerization of methacrylates and styrene, particularly in combination with a small proportion of an ionized agent, capable of producing polymeric emulsions of up to 60 per cent concentration. Examples are given of the preparation of such emulsions of polymethyl methacrylate containing additional emulsifiers and plasticizers such as wool wax alcohols, sodium lauryl sulphate, sodium palmitate, palm oil and dibutyl phthalate. Solutions or finely-divided emulsions of the copolymers may be treated with a solution of a metal salt, e.g. aluminium acetate or calcium chloride, to form a water-insoluble polymeric soap which is resistant to all solvents and reagents and which may be deposited as coatings on various surfaces. Specifications 437,446, 444,257, 532,308, 569,434, 570,326 and 607,704 are referred to.

Title: Improvements in or relating to Telephone Exchange Circuits
Inventor: EKBERGH EVERT OSKAR
IPC: H04Q3/00
Filed: 1968-08-01
Abstract: 1,191,200. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. 1 Aug., 1968, No. 36736/68. Heading H4K. A telephone exchange which may be of the type described in Specification 1,101,567, employs a bidirectional translator incorporating a distribution frame the wiring of which determines directory number to equipment number and vice versa translations. The marker can thus on receipt of a directory or equipment number rapidly obtain the other number. The directory number may be needed for metering purposes. In the cross-bar exchange described the translator employs a number distribution frame with terminals on one side characterizing equipment numbers selectively jumpered to terminals on the other side and characterizing directory numbers. An excess of directory number terminals provide freedom for reallocation. For a P.B.X. a plurality of equipment number terminals are strapped to a single directory number terminal. Coupled to the terminals are relays arranged to code the corresponding numbers. On the equipment number side the relays are arranged in sequentially operative groups of 5, 5, 3 and 11 relays respectively. One relay in each group operates. The first two groups have lockout networks which ensure that in the event of two simultaneous calls only one relay in each group receives holding potential. The first two groups identify the rack and the crossbar switch number within a rack respectively while the other two groups identify a single line or trunk connected to that crossbar switch. On the directory number side, groups of 200 terminals are connected to separate sub-units. Each sub-unit has two " hundreds " relays and twenty " tens " relays (ten for each " hundreds " relay). These relays are further connected to three further groups of five relays. The further groups of relays each register a digit of the directory number in " 2 out of 5 " code. The manner in which individual relays within their groups are selected for operation is not given. A relay, whose circuit is not detailed, fails to operate unless the further groups register a directory number in proper " 2 out of 5 " form. In an alternative arrangement and particularly if sealed contact reed relays are to be used in the speech path electronic equipment instead of relays could be used in the translator.

Title: Improvements in coin gauging and selecting mechanism such as used in coin-freed apparatus
Inventor: ROUNSIVELL WILFRED HOWARD
Filed: 1957-10-02
Abstract: 894,581. Coin testing. FISHER & LUDLOW Ltd. Sept. 8, 1958 [Oct. 2, 1957], No. 37033/59. Divided out of 894,579. Class 27. Coin-testing mechanism including a clearing wall 5 and devices for testing the weight, diameter and annulus thickness and the magnetic and rebound properties of a coin, as described in Specifications 894,579 and 894,580, has the means for pivoting the clearing wall connected to devices for clearing coins trapped by the coin balance' lever and the annulus test mechanism. The coin balance lever 27 carries a pair of feelers 36, 37, one pivoted and one fixed, and as the balance lever lowers under the weight of a coin, the pivoted feeler 37 engages the conical head of an adjustable stud 42 and, if the coin is too thick, is unable to close sufficiently to allow the balance lever to pass the stud. If the coin is not underweight and is passed by the annulus test, the coin balance descends to a lowermost position in which the coin falls out to coin-freeing mechanism but, if the coin is underweight, the balance descends to an intermediate position where the coin is released to a reject shoot 23 or may descend only to a position short of the intermediate position and trap the coin. When a button 8 is pressed to cause a roller 11 to engage a cam surface on the clearing wall 5 to pivot it away from the base-plate 1, a lever 49 is also pivoted and engages a pin 51 on a lever 50 carrying the stud 42 so that the stud is moved to a position in which it can no longer impede movement of the coin balance. A lever 45 is also pivoted and the edge of a slot 47 pressing on a spindle 48 on the coin balance lowers the balance to reject the trapped coin to the shoot 23, this movement being limited by the spindle 48 engaging the end of the slot 47.

Title: Improvements in or relating to the regulation of gas producer plants
IPC: C10J3/24
Filed: 1928-12-17
Abstract: 302,607. Motorenfabrik Deutz Akt.- Ges. Dec. 16, 1927, [Convention date]. Producers.-The temperature in the fire zones of gas producer plants having two zones in one producer, or more than one fire zone in separate producers, is regulated automatically by means dependent on the temperature in these zones or on the pressures in the air inlet pipes to these zones. A double-fire gas producer a has air inlet, pipes b, c, in the latter of which is a fixed damper l. A thermo-electric element d acting through a meter e and relay f sets a resistance g connected in series with a battery h and electromagnet i which controls a damper k in the upper air supply pipe b. If the temperature in the upper fire rises the resistance g in circuit is reduced and the magnet i tends to close the damper k and reduce the temperature of the fire. In a modification differentially connected thermo-electric elements are arranged in each fire for controlling the air supply to the upper fire. In Fig. 3 is shown a differentially arranged piston n connected to the two air supply pipes, so that on increase of air pressure in one pipe, the damper q or r in that pipe is closed by a system of levers p connected to the piston. Other modifications show arrangements for controlling the air supply to more than one producer, and when a falling gas demand takes place.
