Patent DE-2025681-A1 (DE)
Title: Freeing liquids from salts - using combination of strongly - and weakly acid and basic ion exchangers,with electrolytic regenerati
IPC: B01J49/30
Filed: 1970-05-19
Abstract: Combination of strongly and weakly acid cation-exchangers and strongly and weakly basic anion exchangers, which are regenerated electrolytically, is used. Columns contg. individual ion exchangers are arranged so that liquid being freed from salt passes weakly basic after strongly acid and weakly acid after strongly basic exchanger. Also, in electrolytic regneration, H+ breaking through strongly acid cation exchanger are retained in weakly acid one and OH ions breaking through strongly basic anion exchanger in weakly basic one. Technique is esp. useful in treatment of brackish water. 100% current yields are attained in regeneration, loss currents appearing only when weak exchangers are regenerated.
Patent DE-2025846-A1 (DE)
Title: Yarn twisting gauge
IPC: G01N3/26
Filed: 1970-05-27
Abstract: A needle mounted on a friction-free ruby bearing has its head resting on the yarn at a point before it enters the twisting spindle. The degree of twist imposed causes a pre-twisting effect on the yarn and as the needle rests in the groove of the twist, this is converted into an angular measurement by the needle on its pivot. The counterweight end of the needle affects the signal generated by two photo-electric cells, this signal being passed through a rheostat to correct the current to the motor driving the twisting spindle, to keep the degree of twist.

Title: Embossed foamed sheet material - having printed areas in register with embossed areas
IPC: B29C44/30
Filed: 1972-07-29
Abstract: An embossed sheet material, e.g. a floor covering, includes an embossed foamed plastics layer, the thinner sections of which are formed of crushed cells, a colour pattern on the embossed surface in registry with the embossed pattern, and an overlying thin wear layer of transparent resin, the light reflective characteristics of which are different for the raised areas of foam than for the thinner areas. Such a sheet is made by applying a foaming layer to a backing felt or paper layer, heating the layer to semi-cure but not foam it, printing a pattern on the layer, applying a wear layer, heating the printed layer to foam it, and finally embossing the foamed layer whilst still hot between a configured roller and a smooth back-up roller rotatated by movement of sthe sheet. The foam layer may be PVC polyethylene or polypropylene, as may the wear layer.

Title: Stamping and forging press frame - has tool support held separate from main masses until impact to reduce running wear
Inventor: KORB WOLFGANG
IPC: B21J7/02
Filed: 1973-08-16
Abstract: To eliminate the inherent disadvantages of drop-tool machines where a large part of the wear is associated with the running rather than with productive work, it is suggested that the pair of forming tools be kept unconnected from the striker or the anvil, until the actual strike. The pair of tools are held in a guidance frame, drawn apart independent of the main action by hydraulic means for the insertion of the workpiece. This frame receives the hammer blow from the striker and transmits the force through the dampening surrounding the anvil. Thus lighter main frame construction, more accurate tool guidance and longer life are possible.
