Title: Production of pure mgc12 solution suitable for the production of magnesium metal from an impure magnesite ore or concentrate
Inventor: HARRIS BRYN G
IPC: C25B1/00
Filed: 1986-05-29
Granted: 1991-02-12
Abstract: Abstract of the Disclosure A process for producing a substantially pure, concentrated MgCl2 solution suitable for subsequent molten salt electrolysis to magnesium metal from an impure magnesite ore or concentrate is disclosed. The process comprises the steps of calcining a magnesite ore or concentrate at a temperature greater than 600°C to decompose most of the magnesite and form a reactive magnesia, dissolving such reactive magnesia with either concentrated hydrochloric acid or hydrogen chloride gas with the addition of a surface active wetting agent to produce an impure concentrated MgCl2 solution, and reacting such impure concentrated MgCl2 solution with a minimum of excess magnesia to increase the pH of the solution to at least 5.5 to precipitate undesirable impurities from solution and produce a substantially pure MgCl2 solution.

Abstract: The invention relates to multi-element masts and a method of raising a multi-element mast by adding successive elements wherein a direction of traction (15) to be exerted by at least one operator on the free portion (16) of a tieline (8) emerging from a support plate (7) that enables raising the mast elements by the ascending movement of the plate (7) is defined and on a locking device (18) is fixed with respect to a mast guide shaft (4) and allows the portion of the tieline (8) emerging from the support plate (7) to unwind when the support plate is engaged and the tieline is pulled in the defined direction of traction (15). The locking device also permits locking of the tieline (8) against translation in the direction opposite the direction of traction previously defined, substantially at the end of any traction action. A traction device (20) is provided which includes at least one handle element (21) enabling it to be grasped by at least one operator and at least one locking device (22), which, symmetrically to the locking device fixed to the mast guide shaft (4), first, enables locking the traction device (20) via the bias of the locking means against translation on the tieline when the operator(s) urges the tieline in the predefined traction direction (15), and, second, enables free sliding of the traction device on the tieline (8) when the operator(s) suitably holding the free end (11) of the tieline (8) tends to displace the traction device on the tieline (8) in the opposite direction from the defined traction direction (15).

Abstract: ABSTRACT      A lubrication system for supplying viscous, solvent-based, lubricants to heavy industrial plant, such as a driving gear of a sugar mill comprises a reciprocating lubricant pump which is periodically actuated to deliver lubricant to a spray head.  Air is supplied under pressure to the spray head to effect discharge of the viscous lubricant in spray form.  the air supply continues for a pre-determined time after discharge of the lubricant to evaporate solvent in the lubricant and also to clean the spray device.  The pump effects a single stroke for each cyclic discharge of lubricant.

Abstract: ABSTRACT A venting unit is inserted in a press fit within the air vent of a rubber article forming mold and is comprised of a cylindrical body member with an axial bore having a reduced outer end section forming an air inlet open to the mold cavity.  Received for reciprocal axial movement within the bore between an inlet closed position in abutting engagement with. the outer end section and an inlet open position removed from the outer end section is a heat absorbing piston or disc.  The opposite or inner end section of the bore receives a vented plug in a press fit to form a radially inwardly projected shoulder and a spring is held in compression between the disc and the shoulder of the vented plug.  During expan-sion of the rubber article, pressurized air in the mold cavity urges the disc to its inlet open position and is vented to the atmosphere.  As the rubber article reaches its final form, venting of air is completed and any un-cured rubber in the air inlet contacts the disc to set the rubber within the confines of the air inlet.  The rubber in the air inlet forms a part of the molded article which, upon its removal from the mold, will exhibit only a minimal surface irregularity.

Title: Process for the hydrogenation of liquid starting substances that contain carbon
Inventor: KLEIN WOLFDIETER
IPC: C10G1/06
Filed: 1988-11-28
Granted: 1993-04-27
Abstract: Abstract A  process is disclosed for the hydrogenation of starting materials that contain carbon.  In the known processes, the heating of the starting materials to the required entry temperature for the reactor for liquid-phase hydrogenation is effected by means of a heating oven, powered by external heat.  Operating conditions characterized by multiphase flow of gases, vapours, liquid, and solids in the tubes of the heating oven make designing and operating such ovens very difficult.  The new process is intended to make it possible to dispense with an oven of this kind.          The extensive, optimized use of thermal energy by means of heat exchange in counterflow to the starting materials which are a mixture of phases, makes it possible to limit the supply of external heat for heating of a substream of hydrogenating gas in a hydrogenating-gas oven.
