Title: Prodn of two salts from one soln - by crystallisation using evapn by expansion
Inventor: SINGEWALD ARNO DR
IPC: C01D7/00
Filed: 1972-04-20
Abstract: In the prodn. of e.g. NaCl and KCl from a gypsum soln. of Sylvinite type, incrustation is prevented by maintaining a certain amt. of a substance in the circulating soln. which reduces the solubility of the incrustation former. The fresh soln. to be evapd., which is contacted with the crystals formed, is held at a temp. given by the evapn. cycle, then sepd. from the crystals, and added to the circulating liq. A nucleating agent, such as gypsum is added for impurities. The mixt. is stirred, and clarified. The soln. contg. a constant amt. of a substance of max. temp. coefft. of the soln. is passed through preheating condensers and final heaters, and then into the flashing chamber. Water is removed in stages effecting a descrease in temp. At satn. with the substance of max. temp. coefft. of solubility, the substance with lower temp. coefft. which has crystallised is extracted, then expansion is contd. until the substance of higher temp. coefft. has crystallised. The circulating liquid is recycled.
Patent DE-2250946-A1 (DE)
Title: Composite plastic forming tools - comprise electro-deposited metal coating with reinforced backing
Inventor: HAAS EBERHARD
IPC: C25D1/10
Filed: 1972-10-18
Abstract: The metal coating is electro-deposited on a pattern of the component that is to be produced eventually by the finished tool. After deposn., the rear side of the coating, while still on the pattern, is used to spark-erode the surface of a matching back-up piece so that, when these are finally joined, only a very thin layer of adhesive or brazine metal is reqd. By using as the working surface the surface of the deposited coating that has been in contact with the pattern, ther e i sno need for further work on this, unlike when the metal is directly deposited on the backing material, in which case unevenness of coting thickness means that the surface has to undergo a further working operation before the tool can be used. The process saves time and money in tool prodn.

Title: Mobile fluid suction and transport tank - operated by closed medium circuit with injector pump
Inventor: BERGSMANN LUDWIG
IPC: F04F1/02
Filed: 1973-04-04
Abstract: A mobile transport tank with suction and delivery facilities for oil and similar coolants and lubricants has, in addition to the connection for the suction pipe, a connection for a vacuum pipe. The latter is joined to the suction inlet of an injector which is operated in a closed circuit by a centrifugal pump. The fluid then enters the tank through a filter. Reversal of a four-way valve in the injector circuit switches the operation over from vacuum to pressurizing for discharge of the fluid from the tank. Such an injector pump is less noisy than a turbine exhauster and has a better suction height. It is cheaper than a rotary vane-type pump and uses less energy than a compressed air injector.

Title: Double wall plastic boxes - made by folding and bonding without mould tools
Inventor: WILSON PETER CLIFFORD
IPC: H01M50/105
Filed: 1973-08-13
Abstract: The process produces a double-walled box with one base, two sides and ends. The base and two sides are one piece of corrosion-resistant plastic material; a first sheet is folded over to a U-shape with an upstanding lip along the top of each side, a second sheet is folded into a U-shape which fits along this lip to form a double-walled U, two further sheets are folded over this with in-turned edges to form ends which are bonded to the ends of the U, an inner end completes an inner trough shape at each end; outer ends are similarly made with in-turned edges which are bonded to the outer U and an outer trough shape is made from an outer wall at each end; the inner and outer troughs complete the structure leaving a space between the double walls which is filled with foam plastic; this solidifies and forms a nonpermeable honeycomb core. The process is particularly suitable for making battery boxes, no molds are required, the boxes are more easily destroyed than e.g. GRP by an explosion, the foam prevents spread of accumulator acid if the box is fractured.
