Title: Improvements in or relating to the manufacture of mixed water gas and distillation gas from fuels of volatile content
IPC: C10J3/00
Filed: 1927-09-27
Abstract: 279,060. Humphreys & Glasgow, Ltd., (Assignees of Chrisman, C. S.). Oct. 13, 1926, [Convention date]. Producers.-A mixture of distillation- and water-gas is obtained from fuels of volatile content by the use of two gas producers 1, 3, the lower part of each producer being blasted with air and the heat of the blast gases being stored in stoves 4, 2, and by up-steaming one producer, say 1, to liberate coal gas and down-steaming the lower part of the other producer 3 to give water gas which is heated in a stove 2 and passed through the upper part of the up-steamed producer from which the mixed gases are led off. During the " blow " air is admitted through pipes 7 to the gasified zones of both producers and the gases pass from producers 1 and 3 by pipes 9, 10 through stoves 2, 4 and pipes 21, 22 to a heater 5 and stack 28. Air for combustion in stoves 2, 4 is preheated in the air heater 5 and passes by pipes 25, 26 to the top of the stoves, the various valves being suitably adjusted. During the " run " the air supply is cut off, steam is admitted to the top of the gasification zone of producer 1 and the water gas passes through pipe 11 to the base of stove 4 in which it is heated before passing through pipe 10 to the producer 3, and up through the carbonization zone together with the water gas simultaneously made by up-steaming. The resultant mixed water gas and coal gas pass by pipe 16 to a wash box 6 and to storage. The steaming may now be reversed so that an up-run is made in the producer 1 and a down-run in producer 3, the mixed gases being obtained in a similar manner, on operation of the valves necessary. The supply of down-run water gas may be supplemented by gas from storage. In a modified process air blasting may take place between each change over of steaming. Steam may be generated in the stoves by spraying in water through pipes 37.

Title: A method of producing bonded fibre fleeces
IPC: B01J20/28
Filed: 1964-06-22
Abstract: 1,067,775. Laminates. G. SCHICKEDANZ, [trading as VEREINIGTE PAPIERWERKE SCHICKEDANZ & CO.]. June 22, 1964 [July 2, 1963], No. 25775/64. Heading B5N. The bonding agent for a fibre fleece comprises thermoplastic polymeric material which is applied to the fleece in the form of a grid or network of two sets of parallel filaments the filaments of one set crossing those of the other set at an angle of between 5 degrees and 175 degrees. The fibres of the fleece have a length of at least 3 mm. and the filaments are so spaced that their crossover points are spaced more closely than the lengths of the fibres of the fleece. Bonding is effected by the application of heat and/or solvents or swelling agents under pressure. The grid of binder filaments may be sandwiched between two fleeces or merely applied to the surface of a fleece to be bonded. Suitable selection of the crossover angle and of the spacing of the filaments provides a measure of control over the longitudinal/transverse strength ratio of the product. Additional bonding agents may be applied if desired. Suitable materials for the filaments of the grid or network include polystyrene, polyethylene, polypropylene, polyvinyl chloride, poly (meth) acrylates, polyvinyl acetate, polyisobutylene polyvinyl ether polyethylene terephthalate, polyamides and the reaction products of diisocyanates and diols. Synthetic and cellulose staple fibres may be used for the fibre fleeces. Plasticizers and/or crosslinking agents may be incorporated in the binder filaments if required.

Title: Improved method of telomerization and the products resulting therefrom
IPC: C07C33/02
Filed: 1962-07-05
Abstract: Telomers of the formula <FORM:1007830/C2/1> where n is an integer from 1 to 5 and X is a halogen atom, an -OH, -NH2, -CO2H, or -CN group, R1 represents a hydrocarbon remainder, R a hydrocarbon remainder or hydrogen, R1 and R2 hydrocarbon remainders or hydrogen, and n is an integer not greater than 5, one made by causing acetylene hydrocarbons to react on compounds of the general formula <FORM:1007830/C2/2> the reaction being initiated under the stimulus of free radicals, e.g. by exposure to a radiactive radiation such as gamma radiation emitted by a source of cobalt 60, or by decomposition of an organic peroxide.  The process is preferably applied using acetylene with primary, secondary and/or primary alcohols and particularly suitable for the conversion of isopropanol to dimethyl vinyl carbinol with acetylene.  The Specification contains references to alternative high-energy ionising radiations, e.g. a -, b -, g -, X-rays and electron beams, and gives butyne or propyne as suitable acetylenic hydrocarbons. The examples describe the telomerisation of isopropanol with acetylene using dibutyl per-oxide and gamma radiation.  In the latter case the use of aqueous alcohols shows improvement in yields.  In a further example, the reaction rates of ethyl, isobutyl, isoamyl, isopropyl and secondary butyl under radiation initiation have been studied.  Isopropylamine and acetylene under radiation from cobalt 60 gives 1-amino-1,1-dimethyl-2-propene.

Abstract: 704.642. Preparing fibres for spinning. BOURCIER, P. G. Nov. 8, 1951 [Nov. 13, 1950], No. 26198/51. Class 120(1) A machine for separating the pericyclic fibres from textile plant stems comprises a first gripping device for gripping the stems at one extremity and conveying them to a water jet directed on to the stems in substantially their longitudinal direction and a second gripping device comprising means for conveying the stems longitudinally, in a direction substantially opposite to the direction of the jet, whereby complete action of the jet over the entire length of the stems is ensured, the jet operating to separate the fibres from adjacent non-fibrous tissues. As shown, stems 7, with their ends aligned by a moving belt 8 or by a fixed guide plate, are gripped by the first gripping device, comprising a moving belt 13 and a feed conveyer 3, and carried to a water jet 20 issuing from nozzles 30 and 31 (not shown) which direct two flat streams of water violently on to opposite sides of the stems longitudinally thereof. As the stems are released by belt 13, their ends are gripped between faster-moving belts 22 and 23 (not shown), constituting the second gripping device, and they are pulled in a direction substantially opposite to that of the jet 20. An'abutting member which extends between the two nozzles retains the stems within the jet 20 as they are pulled by belts 22, 23 so that the jet acts on the whole length of the stems. Belts 22, 23 are preferably at an angle of 130-160 degrees to the direction of jet 20. Fibres removed by the jet from stems such as those of the broom plant are thrown into a casing 33 which guides them to a washing tank or the like. When dealing with plants which have been previously retted, jet 20 eliminates the retted tissue and the fibres are carried out of the jet by belts 22, 23.
