Title: Improvements in and relating to prepayment mechanisms, for electricity and other meters
IPC: G07F15/04
Filed: 1935-05-20
Abstract: 448,738. Prepayment mechanism for meters. SIEMENS-SCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. May 20, 1935, No. 14735. Convention date, March 23. [Class 27] Coin action, mechanical - connection with delivery proportionate to value of coin; coin - discharging mechanism.-In meter prepayment mechanism giving delivery proportionate to the value of any one of a number (two in the example shown) of coins inserted into a rotary coin pocket 5, the coin engages, according to its size, one or more of a series of driving elements (e.g. the pins 10 and 13), arranged in the same angular position, and adapted to be rotated the same amount but connected by gearing of different ratios appropriate to the different coins with the quantity mechanism 26. The coin pocket 5 is rotated from an external handle 1 by engagement of a crank pin 4 with the inserted coin, and is secured to a central shaft 6 carrying a switch-actuating member 7. The driving pin 10 is carried on a disc connected by a sleeve 9 with a gear-wheel 11, whilst the driving pin 13 is similarly connected with a gear-wheel 14, the gear-wheels 11 and 14 being connected respectively with sun-wheels 20 and 19 of a differential gear. When the smaller and higher value coin is used, the sun-wheel 20 only is operated, but with the larger coin, both sunwheels are operated and rotate in opposite directions, the gear ratios being such that the planet element 22, which is connected with the quantity mechanism 26, is set forward, in each case, by an amount appropriate to the coin. Spring - actuated elements 16 engaging diametrically opposed pins on the gear-wheels 11 and 14, and on the switch actuating member 7, ensure movement of these members through 180‹ at each actuation of the apparatus and cause the coin to be disengaged from between the pins 4, 10, and 13, and discharged, towards the end of the setting action. When the larger coin has the larger value, the gear-wheels 11 and 14 are arranged to drive the sun-wheels 19 and 20 in the same direction. Registering.-A register 24 of the cash inserted is operated from the planet element 22 of the differential gear 19, 20.

Abstract: 1,178,487. Foundry moulds. NATIONAL RESEARCH DEVELOPMENT CORP. 26 March, 1968 [31 March, 1967], No. 14841/67. Heading C3N. [Also in Division C1] Foundry moulds are made by shaping a mixture of mineral fibres and resin, curing, heating in non-oxidizing atmosphere to carbonize the resin, and heating in a hydrocarbonatmosphere to deposit C by pyrolysis in the interstices of the mould. The fibres may be refractory silicates, aluminates, aluminium silicate, oxides, SiC, asbestos, zirconia, alumina, or slagwool. The resin may be an epoxy, phenolic, Friedel-Crafts type, or furane resin curable by heating or catalyst; it may be dissolved in a solvent carrier, e.g. methylated spirit containing hexamine as hardener. The resin may be cured by heating the shaped article to 150-180‹ C. and 400 p.s.i. The carbonization may be performed in N 2  by heating to 820‹ C., followed by pyrolysis at 800-850‹ C., e.g. in N 2 /benzene atmosphere.

Filed: 1918-09-17
Abstract: 119,243. Lindblad, A. R. June 8, 1917, [Convention date]. Cyanides; nitrides. --In the production of cyanides and nitrides in an electric furnace, the nitrogen or nitrogenous gas such as air is drawn into the charge from above by applying suction at a lower level. In an example. a furnace 1 having electrodes 2, 3 is provided with a suction device connected with a gas outlet 5, air being sucked downwards through the charge. Slag formed in the process is withdrawn by an opening 4. In the production of alkali cyanides, the cyanide is carried off by the gas current. When nitrides are being made, the slag outlet 4 is replaced by a larger opening through which the product is raked. The furnace may be partly closed at the top. Specification 22852/14 is referred to.
Patent GB-580508-A (GB)
Title: Improvements in or relating to the production of insolubilised filaments, threads, films or the like shaped products by the wet-spinning of protein solutions
IPC: D01F4/00
Filed: 1944-08-09
Abstract: Artificial filaments, threads, films and the like are prepared by spinning an alkaline solution of vegetable globulin or casein into an acid saline coagulating bath, stretching the coagulated product in an aqueous swelling medium having a pH value approximating to the isoelectric point of the protein, washing in an aqueous non-solvent, non-hardening shrinking bath whilst maintaining the tension, and then treating the product without tension in an aqueous saline insolubilizing bath.  The aqueous bath in which the filaments are stretched may be brought to the appropriate pH value by the addition of a weak base such as aniline or o-toluidine, the alkaline salt of a strong base with a weak acid such as sodium acetate, sodium citrate, or di-sodium hydrogen phosphate, and feebly acidic salts or weak acids such as citric acid, acetic acid, phosphoric acid, boric acid or mono-sodium hydrogen phosphate.  Suitable aqueous non-solvent, non-hardening baths consist of solutions of neutral salts, or dehydrating agents such as alcohol in water.  If desired, the filaments or the like may be given a preliminary stretch, e.g. in the coagulating bath or in an intermediate neutral saline bath. In an example, a solution of pea nut protein in aqueous caustic soda is extruded into a coagulating bath containing sodium sulphate and sulphuric acid, and the filaments passed through a bath containing sodium sulphate in which they are extended about one-third of their length.  They are then introduced into saturated brine from which they are withdrawn, and stretched to twice their length in a bath containing 0.4 per cent of aniline. Thereafter, the filaments are held under tension for one minute in a saturated sodium chloride bath at 40 DEG  C., and finally insolubilized in a bath containing formaldehyde and hydrochloric acid in saturated brine.  In a second example, the filaments which have been spun and given a preliminary stretch in a sodium sulphate bath as in the first example, are introduced into a bath containing 0.4 per cent of aniline in which they are further stretched to twice their length.  The filaments are then passed over successive pairs of skew rollers immersed in saturated sodium chloride solution, whilst the tension is maintained. They are then cut into staple fibre and insolubilized as before. Specifications 513,910 and 543,586 are referred to.
