Title: Improvements in and connected with mining machines
IPC: E21C29/24
Filed: 1924-04-07
Abstract: 228,397. Wood, H. N. April 7, 1924. Coal-cutting machines comprising a cutter mechanism and winding drum mounted on a truck with sprocket and chain gearing between the motor of the mechanism and the: track wheels of the truck have a triangular disposition of sprocket wheels geared together by a single chain, one wheel pertaining to a motor-driven shaft, a second to an axle of the track wheels, and the third to the winding drum. The truck a has wheels b and supports a cutting machine including a motor in a casing d driving a shaft f on which is a sprocket g. The latter drives, by a chain n, sprockets j, m, on the rear-wheel axle and axle of the winding drum l, respectively. The latter carries a brake drum s, around which passes a band t operable from a hand-wheel u through a lever v, w, and may be provided with a clutch for clutching it to the sprocket m. Struts r for preventing the machine from tilting rearwardly and a strut x are also provided. The size of the drum l and of its cable are chosen so that the rate of propulsion due thereto is equal to that due to the wheels b, the cable being taken round guide pins q and serving to haul the truck up steep gradients. The sprocket m serves to prevent fouling of the chain on the sprocket j.

Title: Improved method of and apparatus for sealing the vulcanizing chamber of continuous vulcanizing apparatus
IPC: B29C48/05
Filed: 1947-04-03
Abstract: 627,427. Vulcanizing. WESTERN ELECTRIC CO., Inc. April 3, 1947, No. 9075. Convention date, April 6, 1946. [Class 70] [Also in Group XXVI] In a continuous vulcanizing-apparatus, particularly for vulcanizing the insulating coating of an electrical conductor, water is supplied to a cooling-chamber at the outlet end of the vulcanizing-chamber at a pressure substantially equal to the pressure of steam, the chamber being arranged so that the pressure decreases along the length of the cooling chamber and only a small flow of water through the cooling-chamber is allowed in order to maintain the steam pressure. The material, after passing through the vulcanizing-chamber, passes through a small aperture into a larger-diameter cooling-chamber 31 to which water under pressure is supplied. The material leaves the cooling-chamber through a narrow aperture in the end of an escape tube 46 containing a number of spaced baffies 55 each provided with an aperture aligned with the entrance and exit apertures. At the exit end of the tube is arranged a deflector 65 having an inwardly-directed boss 68 apertured to permit the passage of the material and arranged to deflect any water passing out of the tube. The narrow passages serve to restrict the escape of water from the cooling-chamber and so maintain the pressure. Specification 621,199 is referred to.

Abstract: 526,636. Refining cellulosic materials. HESS, K. March 23, 1939, No. 9205. [Class 2 (ii)] Vegetable material such as straw is subjected to digestion with calcium hydroxide solution and then washed, for example with water, while simultaneously treating the fibres in a beating engine or similar apparatus, and thereafter the fibres are subjected to boiling with dilute caustic alkali solutions. If a dilute acid, e.g. hydrochloric acid, is employed as the washing liquid, the treatment in a beating engine may be omitted. In an example, chopped rye straw is heated with a suspension of milk of lime. After running off the lime, the material is washed in a beating engine until the washing water no longer deposits solids on standing. The fibres are then boiled under pressure with a dilute solution of caustic soda. Specification 493,828 is referred to.

Abstract: 233,856. Dunlop Rubber Co., Ltd., and Macbeth, C. April 14, 1924. Roller apparatus.-Mills for mixing, masticating &c. rubbers &c. are provided with two belts, one of which passes round one of the mill rollers, and the other of which collects the rubber as it passes through the mill, and conveys it to the the upper part of the first belt by which it is again carried through the mill. A belt 1 passes round one of the rolls B of the mill and round a second roll 2, which may be cooled and adjustable. The belt. 1 is guided between horizontal sheaves 7 and may be provided with scrapers, brushes, &c. 12 to prevent material from lodging between it and the roils B, 2. A second belt 3, mounted on rolls 4, 5, 6, 9, 10, is placed beneath the mill and partly encircles the roll 2. Both belts mav be positively driven. The bearings of the, rolls A, B are so formed that the belt 1 cannot be injured in the nip. In operation, rubber &c. is fed to the mill and falls through on to the belt 3, by which it is carried round the roll 2, whence it is carried by the belt 1 back through the mill. The extended path enables the material to cool between its passages through the rolls.

Title: Improvements in the cracking of hydrocarbons to gaseous olefines

IPC: B01J8/24
Filed: 1961-03-15
Abstract: In the production of gaseous olefins by cracking hydrocarbons such as crude oil or a crude oil distillate at 680 DEG -850 DEG C. in the presence of fluidized, hot, inert, heat carrier particles which <PICT:0926844/III/1> circulate between the reactor and a regenerator where the heat necessary for the cracking is supplied by burning carbon deposits on the particles and by combustion of part of the oil residues boiling above 200 DEG C. from the product which have been used to quench the vapour leaving the reactor to below 400 DEG C., the particles used have a grain size between 0,05 and 4 mm., at least 10% having a size above 1 mm.  The feedstock, having a final boiling point of 200 DEG -400 DEG C., is injected into reactor 1 by line 9 where it is contacted with a fluidized bed of hot inert solids, e.g. aluminium silicate containing more than 50% by weight of alumina, corundum, sillimanite or mullite.  The cyclone 11 is adjusted so that the vapours leaving it still contain 5-50 grams of solid per normal cubic meter which prevent carbon deposits in the exit pipe.  The vapours are quenched in vessel 13 with residual oil from line 15; this also removes the solids from the vapours.  From receiver 17 the vapours are introduced into fractionating column 19 where gases and gasoline are recovered overhead, fuel oil by line 28, a rinsing oil for pump 26 by line 25 and quenching oil by line 24.  Solids leave reactor 1 by standpipe 3 which is at an angle to the vertical of not more than 20 degrees and passed to regenerator 2 by riser 4 using air, flue gas or nitrogen introduced by line 30; the amount of solid leaving the reactor is regulated by a gas stream 29.  In the regenerator carbon deposits and oil from line 32 are burned with sufficient excess oxygen to ensure an oxygen content of 0,3-3% by volume in the flue gas.  This gas may be used as a conveying gas. Solids are returned to the reactor by pipes 5 and 6, steam being used as the conveying gas.  Steam is also preferably used as the fluidizing gas.
