Title: Installation for treating fuel briquettes
IPC: C10B53/08
Filed: 1961-06-21
Abstract: <PICT:0986671/C4-C5/1> Apparatus for rendering fuel briquettes smokeless by treatment with an oxygen-containing gas comprises a fuel container 4, the bottom 9 of which is apertured to permit the passage of gases, and means for conducting gases under pressure upwardly or downwardly through the fuel when said container is charged, the apertured bottom 9 being inclined to the horizontal so that it can be loaded with fuel, e.g. coal briquettes, to a uniform depth by discharging thereon briquettes to form a natural slope, and the apparatus having openings 20 and 23 disposed to enable a charge of briquettes to be supplied to and discharged from the container under gravity.  The container 4 may comprise means for altering the angle between the container bottom 9 and the horizontal; also the container may include means for reducing the rate of fall of the briquettes while the container is being filled, e.g. stepwise mounted grates 14...16, hanging chains 17...19 or similar flexible elements, or projections mounted through the apertured bottom. The container 4 includes partitions running parallel to the side walls of the container wherein the distance apart of the partitions is 20 to 25 cms.  Control of the oxidation may be obtained by the introduction of water into the gas flow via the conduit 8, and cooling of the briquettes after the heating may be by spraying the gases and the briquettes with water from the sprays 21 and 22.  The term briquette is used to denote any pressure-moulded fuel pieces, e.g. ovoids, and the natural slope formed by ovoids is 35 to 40 degrees.  The temperature of the apparatus is between 200 DEG  and 400 DEG  C. After the container 4 has been charged, hot gases are provided by a burner 3 and circulated by a blower 2, air being provided, if desired, through a line 7. Specifications 722,495 and 812,822 are referred to.

Filed: 1973-05-12
Abstract: 1471882 Raising molten liquids by gaseous pressure DIMO (HOLDINGS) Ltd 9 May 1974 [12 May 1973] 22743/73 Heading F1R [Also in Division B3] In a method of low-pressure die casting in which gas under pressure is admitted to a furnace 1 containing molten metal and forces the metal up a pipe into a die, the admission of the gas to the furnace is carried out in three independently controlled phases. In the first phase the metal is raised in the pipe as far as the die gate, in the second phase the die is filled, and in the third phase an increased pressure is applied during the solidification of the metal in the die. The ends of the  first and second phases may be sensed by thermocouples or a pressure gauge 37 and the length of the third phase controlled by a timing device actuated by one of the thermocouples on the pressure gauges. Air under pressure is supplied to the furnace 1 from a source 2 through the branches.6, 7 and 8 each provided with a valve 13, 17 and 20 respectively. These valves are operated by air selectively taken from a fourth branch 9 to determine which of the three branches 6, 7 and 8 is opened to the single supply line 22 continuing towards the furnace 1. Thus during the first phase the valve 13 is open and the valves 17 and 20 are closed, during the second phase the valve 17 is open and the valves 13 and 20 are closed and during the third phase the valve 20 is open and the valves 13 and 17 are closed.

Abstract: 301,544. Colas Products, Ltd., Whiting, W. S., and Terry, A. G., (Hammond, T. G. D.). Sept. 2, 1927. Emulsions, making.-Mineral or other aggregate is coated with bitumen by applying a bituminous emulsion in the presence of a small quantity of an alkali salt, not including ammonium salts, which is a strong electrolyte, for example sodium chloride or sodium sulphate, for the purpose of ensuring effective distribution of the emulsion as a coating before the emulsion breaks. The salt may be applied dry or as a solution either to the aggregate or to the mixture of aggregate and emulsion. Suitable proportions of salt to emulsion are 0.5 per cent for sodium chloride and 2.7 per cent for sodium sulphate. A filler such as soft limestone may be added to the bituminous mixture to absorb water set free from the emulsion. In addition to broken stone, gravel, sand, clinker and the like, substances such as sawdust, cork dust, and asbestos may be coated with bitumen by this method.

The inwardly extending fold of a bellows 10 is prevented from expanding radially, when actuating liquid is fed into the bellows, by a metal ring 11 or by providing a substantially thicker portion at the trough of the inwardly extending fold. The actuating liquid is fed to the bellows via a tubular housing 54 from a positive displacement screw type pump and the bellows are contracted by liquid supplied beneath a piston 84, Fig. 1B (not shown), mounted on a rod 60 connected to the closure plate 70 of the bellows. To prevent excessive extension of the bellows the rod 60 is provided with a collar 106, Fig. 1B, which actuates a valve 104 to allow actuating liquid to escape via an outlet 108 to the supply reservoir. To prevent collapse of the bellows a sealing ring 75 is adapted to abut the portion 66 of the pump housing. The displacement of the bellows may be adjusted by varying the rate at which actuating liquid is supplied. In Fig. 3 (not shown) a pair of pumps 2, 2<SP>1</SP> are provided having common delivery and suction. Actuating liquid from positive displacement pump 46 is alternately supplied to the pumps under the control of a spool valve 16. Liquid to contract the bellows 10 is supplied beneath the respective 84 by the piston 84 connected to the expending bellows. The cylinders 76, Fig. 1B, are connected by aline 88 provided with an accumulator 91 having a diaphragm subject to air pressure in chamber 94. Fall in pressure in chamber 94 causes further liquid to be supplied by a pump P. To limit shocks produced by operation of the valve 16, an accumulator 38 is provided in the delivery line from pump 46, a diaphragm 44 separating the actuating liquid from air under constant pressure in chamber 42. The bellows 10 and accumulator diaphragms may be of synthetic rubber.
