Title: Apparatus for operating hydraulic rams
IPC: B30B15/16
Filed: 1979-04-30
Abstract: Apparatus is provided for operating a hydraulic ram device 10 comprising a piston 11 reciprocable in a cylinder 13 between a first inoperative position and a second operative position. The apparatus comprises a pump 16 for supplying hydraulic fluid selectively to either side of the piston, and a gas- charged accumulator 27 for storing hydraulic fluid under pressure. A valve circuit is provided for connecting the pump and accumulator to the cylinder in a first condition in which the pump and accumulator are connected to one side of the piston for supplying fluid under pressure to said one side of the piston to move the piston from said first position to said second position and a second condition in which said pump is connected to the other side of the piston to move the piston from said second to said first position and the accumulator is in communication with said one side of the piston. The arrangement is such that movement of the piston from said second position to said first position forces hydraulic fluid into the accumulator to charge the accumulator. <IMAGE>

Patent GB-2039874-A (GB)
Title: Process for treating cyanide and cyanate containing wastewaters
IPC: B01F3/04
Filed: 1979-07-27
Abstract: A process for treating a cyanide and cyanate-containing aqueous influent such as a wastewater stream (61) is provided. A two-stage method is included for destroying a cyanide-containing influent which comprises: (a) introducing said cyanide-containing influent (61) into a first ozone-contacting zone (Reactor Number 1); (b) contacting said influent (61) in said first zone (Reactor Number 1) with a second ozone-containing gas (78) at least a portion of said second ozone-contaning gas comprising a first ozone-depleted gas (74) withdrawn from a second contact zone (Reactor Number 2) to form a first cyanide-depleted effluent (65) and a second ozone-depleted gas (66); (c) introducing said first cyanide-depleted effluent (65) into a second ozone-contacting zone (Reactor Number 2); (d) contacting said effluent (65) in said zone (Reactor Number 2) with a first ozone-containing gas (71) to form a second cyanide-depleted effluent (83) and a first ozone-depleted gas (74); (e) withdrawing said first ozone-depleted gas from said second contact zone (Reactor Number2); and (f) withdrawing said second cyanide-depleted effluent (83) from said second zone (Reactor Number 2). A single stage method is also provided in this invention. Both single stage and double stage embodiments employ a turbine-gas injector (64) in each ozone-contacting zone to accomplish a high mass transfer of the ozone-containing gas to the influent. In both the single stage and double stage method, the cyanide-depleted effluents may be recycled to the aqueous influent stream prior to its introduction to either the first or second ozone-contacting zone or to the contacting zones themselves to destroy cyanides and cyanates in these effluents. This destruction is accomplished by allowing residual ozone or other oxidising species in the recycled effluent to react with the cyanide/cyanate species and reducing influent concentrations by diluting the influent entering the contacting zones while it the same time obtaining lower ozone-containing gas to liquid (G/L) ratios.

Patent GB-2069876-A (GB)
Title: Removal of granular material from mineral wool
IPC: B07B9/00
Filed: 1980-02-26
Abstract: In a process for the removal of granular material from mineral wool in the form of matted fibre, (50) the wool is teased between spiked rollers (214) to form tufts of fibrous material of reduced granular content with consequent loosening of the granular material present in the wool. The tufts are conveyed, suspended in air, to a chamber (22) having a perforated floor (24) and an exit (25) at a higher level. The air-suspended tufts are circulated in the chamber to form a relatively dense, granule-rich fraction which falls through the perforated floor and a lighter, fibre-rich fraction which is extracted through the exit (25). The process can be operated without causing too great a reduction in the length of the fibres present in the wool and without causing an unduly high proportion of them to form into fibre balls. The product is specially useful as reinforcement for boards made by papermaking processes. <IMAGE>

Title: Snail trap
IPC: A01M25/00
Filed: 1980-03-21
Abstract: A snail trap having a container 10 which is fitted into the ground up to its rim and which contains a liquid bait which entices snails. Prior to capture the snails drink the liquid, lose their sense of balance and drown in the liquid. To facilitate the removal of carcasses from the liquid, a sieve-like collecting device 20 is disposed in the container, and rests on the bottom of the container. The collecting device can be lifted out of the container in a convenient manner by means of an upright 30 which projects above the rim 11 of the container, and a cover 40 is provided on the upright to protect the liquid bait from rain. If the upright 30 is of hollow construction, it can accommodate a float 50 for indicating the level of the liquid. <IMAGE>
Patent GB-2050561-A (GB)
Title: Outer Tube of Telescopic Shock Absorber
IPC: B60G13/00
Filed: 1980-05-09
Abstract: An outer tube (12) of a telescopic type shock absorber is formed in such a manner as to have its rigidity decrease from a lower end to an upper end thereof. The rigidity in the lower end portion is sufficient to withstand the maximum bending stresses which occur at the lower end where the tube 12 is fixed to a knuckle spindle 13. The reduced rigidity in the upper portion allows the outer tube 12 to bend with the piston rod and reduces the frictional resistance between the piston rod and its guide. The rigidity of the upper end of the outer tube 12 is decreased by plastic stretching of the upper end of the tube (12) during manufacture, to reduce its wall thickness. <IMAGE>

Title: Chuck operation
IPC: B23B31/30
Filed: 1980-09-08
Abstract: A fluid operating mechanism providing a fluid coupling of stationary and of rotary parts, has, in the rotary parts, a cylinder 20 with a piston 22 defining therein opposite chuck closing 26 and opening 24 cylinder ends, and ports in both coupling parts which, together with two fixed conduits 42, 46 form fluid passages to respectively the chuck closing, and opening cylinder ends, with each passage having an interposed check valve 56, 70 and an associated plunger 58, 72 of which the check valve in either passage will open to admit fluid into, but will normally close to block fluid flow from, the associated cylinder end, and the plunger associated with the check valve in either passage will open this valve on being subjected to the pressure of fluid in the other passage. At least the plunger associated with the check valve for the chuck-closing cylinder end is a stepped plunger with opposite larger 94 and smaller 92 faces, of which the larger face is subjected to the pressure of fluid in the chuck-opening cylinder end and the smaller face is subjected to the pressure of fluid in the passage to the chuck-closing cylinder end ahead of the check valve therein, so that this check valve can be opened for blending the fluid in the chuck-closing cylinder end with fluid of a lower control pressure applied to the passage to this cylinder end ahead of the check valve therein on admission to the chuck- opening cylinder end of fluid lower than the control pressure.   <IMAGE>

Title: Process for the production of synthesis gas from coal
IPC: C01B3/32
Filed: 1982-01-18
Abstract: The overall conversion of coal to synthesis gas by pressurised counter- current gasification is improved by steam reforming the methane values in the gas and heating the steam reformer by means of a fluidised bed combustor fuelled by the coal fines which are too small to be employed in the gasification step.
