Title: Coin inlet mechanism for prepayment apparatus
IPC: G07F15/02
Filed: 1940-04-29
Abstract: 537,939. Coin-action. LANDIS & GYR SOC. ANON. April 29, 1940, No. 7628. Convention date, Feb. 29, 1940. [Class 27] To economize space the rotary coin-receiving and quantity mechanism operating drum 5 is arranged verticaly or substantially so. The coin is inserted through a slot 3 in the outer casing 2 into a shoot 8 in the drum 5, and the latter is then rotated by bevel-gearing from an outside knob 6, till the coin aligns with a shoot 15 and drops down into the container 16. The top of the coin engages a slot in a projecting cylinder 10 which is geared to the quantity mechanism. A false base may be inserted in the slot to enable smaller sized coins to be used. Fig. 3 shows a drum 5 slightly inclined to the vertical, the shoot 8 being closed at the inner end, and a halfturn being necessary to be imparted to the drum by the knob 6 to allow the coin to fall by way of its entry slot down into the shoot 15.

Title: Method of Producing Elastic Woven Fabrics and Knitted Goods
IPC: D06M15/333
Filed: 1968-02-16
Abstract: 1,168,574. Producing elastic woven and knitted fabric. KURASHIKI RAYON K.K. 16 Feb., 1968 [16 Feb., 1967], No. 7808/68. Heading DIP. Elastic woven or knitted fabrics are produced by applying to the surface of polyurethane continuous elastic filaments an aqueous solution of polyvinyl alcohol having a degree of saponification of 50-100%, heating and drying them while stretched to at least 150% of their original length to produce polyurethane filaments whose elongation is not greater than 100% and whose Young's modulus, expressed in terms of tenacity at 50% elongation, is at least 0.4 gram per denier, making woven or knitted fabric from these filaments with a non-elastic yarn and treating the resulting fabric with water at 60‹-100‹C to remove the polyvinyl alcohol and cause shrinkage of the fabric. The polyvinyl alcohol which may have a degree of polymerization of 300-4,000 may be applied to the filaments as a 1-30% by weight aqueous solution by dipping, spraying or by means of rollers, 5-200% by weight of the polyvinyl alcohol preferably being applied to the filaments. Stretching may be effected prior to, during or after application of the polyvinyl alcohol to the filaments, the filaments being maintained in the stretched condition during drying, e.g. at between room temperature and 100‹C. The filaments are preferably given a heat treatment at a temperature of from 60‹C to a temperature just below the decomposition temperature of the filaments during at least a certain period before the completion of the' step of drying in a stretched state. As a result of the treatment with hot water the woven or knitted fabric may shrink by 20-80%. The polyurethane continuous elastic filaments may be produced by dry-spinning, melt-spinning or wetspinning a polyurethane polymer obtained by the reaction of a polymer glycol having a melting point of not more than 80‹C, e.g. a polyether glycol, polyester glycol or polyether ester glycol, with an organic disocyanate, e.g. ethylene or hexamethylene diisocyanate, cyclohexane 1, 4-diisocyanate, tolylene diisocyanate, biphenylene 4, 4'-diisocyanate, diphenyl methane 4, 4'-diisocyanate and 1, 5-naphthylene diisocyanate, and a chain extender, e.g. hydrazine, ethylene diamine, tetramethylene diamine, hexamethylene diamine, 1, 5-naphthylene diamine, p-phenylene diamine, ethanol, aminoethylethanolamine, ethylene glycol, propylene glycol, 1, 4-butanediol, 1, 5-pentanediol and water. Suitable non-elastic fibres yarns which may have been subjected to a bulking treatment are polyester, polyamide, polyacrylonitrile, polyethylene, viscose rayon, and cotton fibre yarns. The polyurethane filaments and non-elastic fibre yarns may be in the form of blended yarns, core yarns or plied yarns when made up into woven knitted fabrics.

Abstract: 773,501. Automatic speed control systems. JONES & CO. (ENGINEERS), Ltd., W. March 16, 1955 [March 17, 1954], No. 7810/54. Class 38 (4). [Also in Group XXXVII] In order to prevent wear in the centrifugallyoperated field-controlling contacts of a speedregulating system for a dynamo-electric machine, the contacts control an A.C. generated by the machine which is rectified before being applied to the field. The invention is described as applied to a motor-alternator invertor, in which a D.C. compound motor 1 energized from a battery 2 is mounted on the same shaft 3 as a salient-pole polyphase alternator 4. The contacts 8, 9 of a centrifugal governor 10 mounted on shaft 3 open and close once per revolution of the shaft, thereby controlling the A.C. supplied from the alternator output phases to rectifiers 7 supplying auxiliary shunt fields 5 of the motor to vary the average value of auxiliary excitation. Alternatively, a single auxiliary field may be supplied from a single phase of the alternator. A D.C. motor only may be controlled by deriving an A.C. from its armature for application to the motor field as already described.

IPC: D06N3/02
Filed: 1929-03-13
Abstract: 332,257. Scholz, V., and Atlas Ago Chemische Fabrik Akt.-Ges. March 13,1929. Adhesives.-Linoxyns or linoxyn-like substances are made from drying or non-drying oils containing unsaturated groups or from their fatty acids by blowing with air or other oxygen-containing gas until no further oxidation or polymerization can take place and then kneading the product with air, whereby the oxidation and polymerization are carried to a further stage and a light-coloured, granular material having a relatively high melting point is produced. Linseed oil, with or without ¢ to 2 per cent of a catalyst such as litharge or lead linoleate is blown with air at a constant temperature of 60‹-150‹ until the passage of air is practically stopped by the viscous mass, which is then kneaded with access of air at a temperature of 100‹ C. for 3-4 hours. Half per cent to 2 per cent of organic bases such as aniline oil, naphthylamine and urea may be added during the blowing or kneading. Other suitable oils include wood-oil, Para rubber seed oil, perilla oil, sunflower oil, nut, hemp and castor oils alone or mixed. Five parts of resin and 3 parts of kauri-copal may be added to 25 parts of the kneaded product to form linoleum cement which with the addition of pigments and fillers may be made into linoleum base. Nitrocellulose may be incorporated with the linoxyns to form materials suitable among other purposes as adhesives. By dissolving linoxyns in alcohol at a temperature of 100 to 150 C. and at a pressure of 2 to 10 atmospheres, evaporating the alcohol, and mixing the " solution linoxyn oil " formed with gun-cotton or celluloid solutions, with or without the addition of aniline oil, castor oil or old caoutchouc. The viscous solutions formed by evaporation of the nitro-cellulose solvents may be thinned without decomposition by heating to a temperature of 80 to 120 C. Alternatively homogeneous, transparent materials (" linoloids ") which may be elastic, tough or hard, according to their nitrocellulose content are prepared by kneading the linoxyns with nitro-cellulose or celluloid swellings, evaporating the solvent unifying the resulting mass by rolling.

Abstract: 956,626. Gain control. FERGUSON RADIO CORPORATION Ltd. April 11, 1963 [March 6, 1962], No. 8616/62. Heading H3Q. In an amplifier using a pentode valve, in which gain is controlled by variation of the suppressor grid potential, distortion is prevented by feeding part of the signal to the suppressor grid. Signal is applied to the grid of a pentode video amplifier from terminal T1, Fig. 2, and the gain controlled by means of a variable negative suppressor grid-bias derived from potentiometer R3. Distortion arises when the gain is reduced to small values, but is obviated by connecting a resistor R4 in the suppressor grid lead and feeding part of the signal to this grid by way of potentiometer R1 and coupling capacitor C2. At high frequencies a part of the signal can reach the following stage over the suppressor grid to anode capacity C3, Fig. 3. To compensate for this, the cathode bias resistor R5 is not by-passed and a part of the signal fed from this to the cathode of the succeeding stage via capacitor V5. The cathode circuit of this succeeding stage comprises a bias resistor R6 and shunting capacitor C6, which is so chosen that the signal fed over the network C5, C6, R6 is equal to that reaching the grid of the valve over the suppressor grid to anode capacitance C3, the grid resistor R2 and the input capacity C7 of the succeeding stage. The values of the cathode resistor R6 and capacitor C6 may be so chosen as to improve the high frequency response of the arrangement. The arrangement may be used for remote control of gain.
