Patent GB-890656-A (GB)
Title: Process for the safe handling of gaseous acetylene under pressure
Inventor: BRACONIER FREDERIC FRANCOIS AL
IPC: C07C7/20
Filed: 1959-01-12
Abstract: Acetylene under pressure is stabilised by mixing with gaseous ammonia in a weight ratio of ammonia to acetylene increasing regularly from 0 at 1 atmosphere to 4 at 50 atmospheres absolute pressure.  This is preferably accomplished by dissolving the acetylene in liquid ammonia, compressing and heating to obtain a gaseous acetylene/ammonia mixture which may be stored or transported safely. Before use the acetylene may be freed of ammonia by washing with water.  Ammonia vapours leaving the acetylene absorption stage may be recovered by washing; the evaporation of ammonia may be used to control the temperature in the absorption tower.  The acetylene solution may be heated in a tower containing condensing means in its upper portion to control the ammonia concentration in the mixture.

Title: A process for the manufacture of elastic artificial masses prepared by the interaction of polysulphides and dihalogenated hydrocarbons
IPC: C08G75/16
Filed: 1936-01-14
Abstract: Elastic artificial masses in granular form are prepared by the interaction of polysulphides with dihalogenides of paraffin hydrocarbons in an aqueous medium in the presence of a watersoluble alkyl cellulose, the quantity of alkyl cellulose being preferably less than 1 per cent.  In examples, a solution of methyl or ethyl cellulose in water is added to an aqueous solution of sodium tetrasulphide, the mixture is heated to 40--50 DEG  C., and dichlorethane is allowed to flow in so slowly that the temperature does not rise above 78--80 DEG  C.  The yellow granular product obtained is washed with hot water.  Alternatively, the alkyl cellulose may be directly dissolved in the polysulphide solution. The dried granular product can be rolled into sheets.

Patent GB-966495-A (GB)
Title: Vapour phase hydrocarbon conversion
Inventor: ELLERT HENRY GEORGE
IPC: B01J27/06
Filed: 1962-01-15
Abstract: Hydrocarbons are converted to other hydrocarbons by contact in the vapour phase at an elevated temperature with vaporous hydrogen flouride and a high surface area solid inert to hydrogen fluoride, preferably activated carbon. The following conversions are stated to take place:  (a) liquid paraffinic hydrocarbons are converted to aromatic hydrocarbons usually of higher boiling range and gaseous olefins and paraffins, e.g. heptane yields C9-C12 alkyl benzenes and C1-C3 hydrocarbons, (b) paraffins containing not more than four carbon atoms are converted to higher boiling hydrocarbons, e.g. butane yields a liquid product comprising C10-C20 acyclic mono-olefins and some C1-C3 hydrocarbons, (c) a mixture of aromatic hydrocarbon and a paraffin is converted to an alkyl aromatic hydrocarbon; when the aromatic hydrocarbon is already alkylated some conversion to tricyclic compounds occurs whether or not a paraffin is present.  Alkylation tends to produce ortho-, para- and 1,2,4-derivatives.  In one preferred embodiment a virgin, catalytic or thermal naphtha is treated to obtain a heavy aromatic product which may be hydrogenated, with hydrogen obtained in the conversion, to obtain jet fuel.  In another embodiment a low-boiling fraction from a reformate or a raffinate from solvent extraction or a reformate is treated to increase its aromatic content and recombined with the remainder of the reformate.  Suitable conditions are 600-1300 DEG  F., 0-400 p.s.i.g., hydrogen fluoride to hydrocarbon weight ratio 0.1-4 and a L.H.S.V. of 0.05-4.  The solid contacting agent may be activated carbon, calcium fluoride or magnesium fluoride and may carry 0.1-20% of a Group II, III or VIII metal or oxide or fluoride thereof.  Small amounts of boron trifluoride and/or water may also be added to the hydrogen fluoride.

Abstract: 325,077. Highfield, F. W., and Highfield Electrical Co., Ltd. Jan. 16, 1929. Protective or safety devices, auxiliary. - A protective device for portable electric motors comprises a holder for carrying the motor relative to which the stator can turn and a switch which is actuated by the relative movement of the stator and holder. As shown applied to a motor driving a portable drill, the stator a is rotatably held in the holder b by means of rings c carrying balls or rollers d and the stator is retained in the normal position by a spring e acting on a lever f attached to the stator. The lever f is connected to a bell-crank lever k which engages at its other end with a shoulder formed on a plunger h whereby a movable spring contact i is kept in engagement with a contact j. If the torque exerted by the motor becomes excessive, the stator rotates, the plunger h is released and the contacts i, j are separated. To re-establish the circuit, the outer end of the plunger is pressed in until the lever k engages the shoulder. A spring m is provided to move the plunger on release.

Filed: 1964-01-14
Abstract: 1,009,497. Road surfacing machines; tanks. J. H. HOLLAND CO. Jan. 14, 1964 [Jan. 14, 1963], No. 1594/64. Headings E1G and E1T. A road surfacing machine comprises a sprayer to apply a coat of asphalt to the surface, a spreader for depositing aggregate over the asphalt and means for compacting the aggregate into the asphalt. A chassis 16 carries a primemover 12 driving six pneumatic tyred front wheels 44 by shaft 58 and chain 78 and have five rear wheels 80, offset in tracks to provide continuous compaction coverage of the surface, steerable through a yoke 86. A centrally mounted asphalt tank 22 is heated by an internal flue 40 from a gas heater 34 and supplies hot asphalt to nozzles in a spraybar 274 through a pump 410, the tank being replenished from a semitrailer supply tank 14. An aggregate receiving and distributing hopper 100 is mounted on the front end of the chassis and has means 220 to engage the wheels of a dump truck to allow filling of the hopper on the move. The hopper 100 has an extension 134 which together with extensions 278, 280 allow spraying and aggregate distribution over a wider area.  In operation the machine is driven up to the dump truck to engage rollers 214 with the rear tyres and arms 222, 232 are moved inwards by a hydraulic jack to engage rollers with the tyre sides and the rim interior. Aggregate is shot into the hopper 100 as required, while the machine pushes the dumptruck, and is spread by an auger roller 176 to a feed roller 178 supplying the aggregate to a number of gates adjustable by levers 132. When the hopper extension 134 is in use a corresponding auger and gates 152 operated by screws 156 provide similar adjustable distribution. The heated asphalt is pumped from the tank 22 to the spraybar 274 which has a number of nozzles 294 each centralled by a three-way valve 292 such that the asphalt may be sprayed or returned to the tank if the valve is shut. The spraybar extensions 278, 280 are hinged and have their inlet 286 and outlet 290 ducts connected by flexible hoses 334, 336, the outlet ducts 290 leading a pipe back to the tank system. The weight of asphalt in the tank 22, which is replenished by syphoning from the trailer tank 14, maintains a substantially constant load on the compacting wheels 44, 80 and, due to the proximity of the base of the tank with the surface, retains the sprayed asphalt at working temperature during compaction. A series of valves in the asphalt pipe lines provides for filling and emptying of the tank 22, the circulation of asphalt to provide mixing in both tanks 22 and 14 and means for clearing and cleaning the system.
