Title: An improved process for preparing carbon black and hydrogen
IPC: C09C1/54
Filed: 1938-02-23
Abstract: 509,166. Carbon black; hydrogen. TRIGGS, W. W. (Bayerische Stickstoff-Werke Akt.-Ges.). Feb. 23, 1938, No. 5699. [Class 90] In the production of carbon black and hydrogen from hydrocarbons, or mixtures, which are split with the evolution of heat, e.g. acetylene, the quantity of gas supplied to the reaction chamber exceeds by at least 10 times, preferably 50 or 100 times, the quantity necessary to maintain a continuous splitting flame under the reaction conditions. The gas stream may, if desired, be split into several portions, the total quantity of gas fulfilling the above conditions, and it may be turbulent or in the form of uniform laminar streams, as desired. Suitable hydrocarbons include acetylene, vinyl derivatives, olefines, cyclic and other endothermic hydrocarbons and mixtures thereof with other hydrocarbons, e.g. methane, ethylene, benzene, cyclohexane, naphthalene, &c., and also mixtures with nitrogen or nitrogencontaining gases. Such admixtures influence the properties of the final products, e.g. the addition of methane and illuminating gas increases the production of hydrogen and forms a less active black, which yields soft and elastic vulcanisates when incorporated in rubbers or synthetic rubbers. The addition of naphthalene increases the yield of black and its activity. The addition of nitrogen gives a pure nitrogen-hydrogen mixture which may be used for the synthesis of ammonia. The process may be initiated in known manner, e.g. by electric sparks, heated surfaces or partial combustion of gases, and may be carried out in the presence of small quantities of additional substances which yield heat, but insufficient to seriously contaminate the reaction products, e.g. oxygen may be added in an amount less than one-fifth of that necessary to burn the hydrogen which could be formed. Likewise gaseous catalysts may be added, e.g. metal carbonyls, in such quantities that the ash content of the carbon black is less than 1 per cent, and preferably less than 0.1 per cent. The process maybe carried out at ordinary or increased pressure, e.g. up to 2 atmospheres and the carbon and hydrogen, directly after formation, may be rapidly cooled, to avoid or check undersirable changes. The cooling may be carried out by liquids, e.g. a steam boiler ; or by adding gaseous or vaporizable substances of good thermal conductivity and/or high thermal capacity, e.g. hydrogen, nitrogen, polyatomic gases, water or other readily vaporizable compounds, or by recirculating the hydrogen obtained in the process ; or the process may be coupled with other processes requiring heat e.g. the decomposition of methane. According to an example, 150 cubic metres of acetylene per hour were split in a water-cooled nozzle of 50 mm. internal diameter leading into a tubular chamber about 1 m. in length. The amount of grit in the product was 3-5 per cent, and no methane was formed. The minimum quantity of acetylene required to maintain the flame was 5 cubic metres per hour.

Title: Clothes wringer
IPC: D06F45/00
Filed: 1936-02-26
Abstract: 465,424. Wringers. SCHROEDER, S. E. Feb. 26, 1936, No. 5819. [Class 138 (ii)] The lower roller of a wringer is raised into operative engagement with the upper roller, which is subjected to the usual yielding pressure, by means operated by the rotation of the roller shaft and is retained in that position by the pressure existing between the rollers until such is released either normally or by the wrapping of an article around the upper roller. The upper roller shaft 29, Fig. 6, is journalled in a casing 21 pivotally supported on, and normally latched to, a stationary frame 20, carrying the lower roller shaft 53. The pressure - applying, latching and releasing mechanisms are those described in Specification 466,230. The lower roller shaft is journalled in stirrup members 52 slidably mounted in guides 51 within the stationary frame 20 and provided with integral depending fingers 53 which engage cams 76 secured to a shaft 50 extending beneath and parallel with the lower roller. An arm 68 also is secured to one end of the cam-shaft 50 and carries a block 69, Fig. 3, slidably mounted thereon. Upward movement of the block is limited by a pin, and a spring 73 anchored at its upper end to a fixed point on the stationary frame and at its lower end to an arm 70 on the block 69 normally keeps the arm 68 vertical so that the fingers 53 engage in recesses 79 in the low portions 77 of the cams 76 and the lower roller is retained out of contact with the upper. An arm 65 is secured to the lower roller shaft and is provided with a shaped head 66 to engage the block 69 whereby, according to the directions of rotation of the lower roller, the arm 68 is swung to the left or right to raise one of the high portions 78 of the cams 76 into engagement with the fingers 53 to raise the lower roller and stress the spring 73. The fingers rest in notches 79a in the cams until, on release of the pressure between the rollers, the spring 73 restores the cam-shaft 50 to normal position permitting the lower roller to descend to inoperative position.

Title: Control valves for vehicles
IPC: B60T13/12
Filed: 1971-03-05
Abstract: 1376192 Brake control valves GIRLING Ltd 18 Feb 1972 [5 March 1971 25 June 1971] 6146/71 and 29826/71 Heading F2F In an hydraulic brake control valve, a manually actuated piston 8 opens a first spring- controlled needle valve member 26, controlling communication between a first passage connected to a high pressure source and an outlet port connected to a wheel brake hydraulic actuator, and closes a second, oppositely acting spring-controlled needle valve member 27, controlling communication between a second passage connected to a reservoir and the outlet port 44, each valve member communicating its respective passage with a respective chamber 5, 36, the chambers being axially spaced but in free communication with each other, the first valve member being controlled directly by the piston and the second valve member being controlled indirectly by at least one longitudinally extending push-rod, both members being guided in longitudinally extending bores in opposite ends of a body portion 7 which separates the chambers. The piston 8 integral with a pedal input rod 9, actuates the first member in a plug 18, and via push-rods 41 the second member 27 in a plug 19. Movement of the piston 8 cuts-off fluid flow from the outlet 44 to a reservoir via bores containing the push-rods 41 and other bores through the portion 7, and opens the second valve member 27 to communicate fluid from an accumulator, through a passage 35 to the outlet 44. To equalize pressures at the piston 8, a bleed passage 12 and a plate valve 13 are provided. Two such control valves are positioned side-by-side and are operated by a balance-beam from a pedal, Fig. 1 (not shown); these valves actuate the same or different brakes on the same wheel, or on different wheels. As shown, a floating piston 50, when the brakes are not actuated, allows fluid communication between a second outlet 61 and a reservoir through passage 59. Upon piston movement due to pressure build-up at the outlet 44, a valve 58 closes such communication, and contraction of the volume in a chamber 60 increases fluid pressure at the second outlet 61, thus providing tandem operation. Therefore the tandem valve in Fig. 3, operates brakes in a similar manner to the dual valves in Fig. 1. In the event of pressure failure in the chamber 36 push-rods 54 operate the floating piston 50 mechanically.
