Title: Industrial effluent evaporating system - using waste heat from power stations in expansion evaporators
Inventor: WILCK ADOLF-FRIEDRICH DIPL ING
IPC: C02F1/04
Filed: 1973-03-20
Abstract: An industrial effluent treatment plant evaporates the effluent in expansion-type evaporators which are, as regards the water circuit, a part of a closed cooling water loop with a heat source. On the vapour circuit they are connected with condenser elements, coupled to a distillate collector. These evaporators are arranged below the condenser elements (echelons of ribbed tubes) and the pusher fans at the food of these elements. This makes it possible to utilize the waste heat of larger power stations. The ecological disturbances caused when the latter use river water for cooling are eliminated.

Title: Single paper sheet stack separator - has self adjusting brake to prevent transport of more than one sheet from random stack
Inventor: SCHNEIDER ADOLF
IPC: B65H3/04
Filed: 1973-06-23
Abstract: The stack of paper is held onto a sloping table by a spring loaded pressure plate, the edges being held by a vertical plate preventing the stack from sliding off the table. On the lower end of the surface on which the paper rests is an opening where a belt-driven separating drum asserts pressure against the bottom sheet, thereby moving it forward underneath a flexible guide strip, which in turn is held against the separating drum by a spring loaded automatically adjusting brake-shoe. The guide strip and brakeshoe arrangement prevents more than one sheet being taken off.

Title: Large decorative duroplast panels esp. for building facades - cast on intermittently supported thermoplast sheet to give undulating face
Inventor: JANSEN EWALD
IPC: B29C33/00
Filed: 1973-09-28
Abstract: A casting mould and a method for the mfr. of large cast panels of enriched duroplastic casting resins, esp. polyester or methacrylic resins, possessing decorative moulded surfaces are as follows: a soft, thermoplastics sheet is stretched over a number of supports such as timber battens, projections, metal sheet, large-headed nails or screws, which are themselves fixed to plywood or similar board; the duroplastic resin is then cast into this thermoplastics sheet which, as a result of the weight of the liq. resin, hangs in a series of depressions between its supports, thus giving an undulating or similarly patterned surface to the finished moulding. The height of the supporting projections above the base board is sufficient to prevent the thermoplastics sheet coming into contact with it. Esp. used for making very large, e.g., 3.00 times 1,50 m. facade panels for buildings. The matl. and labour required to produce an excellent finish are extremely economical.
Patent DE-2352721-A1 (DE)
Title: Cable twisting bobbin braking system - with assymetrical brake pad linked to disc for setting and adjustment
Inventor: HERTEL PETER
IPC: D07B7/06

This gives a low wear performance, increasing the operating life of the components, in an arrangement where they can be set to the required adjustment from the operative's side of the bobbin frame, in a simple procedure.
Patent DE-2360967-A1 (DE)
Title: Concrete or ceramic tiles of any shape - produced for flooring or wall coverings
IPC: B28D7/04
Filed: 1973-12-07
Abstract: Tiles of any shape and surface roughness are produced by extrusion and are used for wall and floor coverings. A pliable green matl. which can be hardened or fired, e.g., concrete or ceramics, is extruded into long shapes, the cross-section of which corresponds with the desired cross-section of the tile. The long rod of tile matl. is then hardened or fired. The extruded rod which is now hard is then cut into slices of desired thickness to form tile. The surface roughness of the faces of the tiles is determined by the cutter used; the cutter may be a circular saw with a diamond impregnated cutting edge.

Title: Plastic tamper-proof bottle sealing cap - has rack engaging with neck thread to burst open on turning
Inventor: GOLDE ERICH DIPL ING
IPC: B65D55/12
Filed: 1974-03-22
Abstract: On the inside of the cap is an annular or intermittent protrusion, snapping into engagement behind an annular bead on the bottleneck when it is pressed into position, thus securing it permanently. There is a vertical groove in the inner cap wall, in which a rack slides. This engages with a relatively coarse-pitched thread, and on turning the cap to the left the rack bursts open the top part of the cap, in which there is a weakened line. There can be a point at the top end of the rack, which can be arranged to thrust the top part of the cap up far enough for it to be gripped and torn off. The weakened line can run round the cap in a nearly complete circle, enclosing a central sealing stopper.

Title: Purification of gas mixts contg sulphur dioxide - by scrubbing with aq soln contg calcium carbonate, hydroxide, oxide and chloride
Inventor: HOELTER HEINZ
IPC: B01D53/50
Filed: 1974-04-01
Abstract: Purification of stack gases or other gas mixts. contg. SO2 by scrubbing with aq. soln. contg. CaCO3 and/or Ca(OH)2, from which CaSO4 and other scantily soluble substances are subsequently removed, is improved by addition of CaO and Cl- ions (pref. CaCl2) to the circulated scrubbing soln. The pH of the soln. before it contacts the gases should be 8 or more; after the scrubbing 6-7. Dust, HCl and HF, if present, are also removed from the gas mixt. Scrubbin efficiency is improved (up to 99% SO2 is removed from the gas mixt. compared with about 70% in the known process). Encrustations within the apparatus are eliminated. Calcium sulphate and other scantily soluble substances withdrawn from the scrubbing liquid can be calcined to produce a gypsum-contg. mixt. The latter can be mixed with fillers (pref. fly ash) and binders (pref. cement) to produce building materials.

Title: Inert gas produced by hydrocarbons combustion and shock cooling - then second cooling scrubbing adsorption and drying
IPC: C01B32/50
Filed: 1974-05-17
Abstract: A method of producing inert gas by combustion of liquid or gaseous hydrocarbons with air, opt. with admixture of a gaseous atomising agent such as steam, gas, inert gas or air, consists of applying a shock cooling immediately after combustion, esp. by spray cooling, followed by second cooling and scrubbing, using water or an aqueous solution close to freezing point; the gas treatment is completed by absorption drying. The washing and cooling liquid may be recycled, cooled again and re-used in the cooler and scrubber. A portion of the inert gas, after passing through the absorption dryer, may be continuously or intermittently branched, heated and used for regenerating a second dryer, then returned to the combustion chamber. Used for any purposes where inert gas is required, e.g. in tank ships and transporting tankers for neutralising empty tanks and forming a gas blanket in a filled tank, and for transportion of easily decaying foodstuffs such as fish meal. The appts. can be operated with minimum inertia, minimum heat for drying and can be used for burning fuel oil or diesel oil having a high sulphur content 4%. The inert gas obtd. has a very low oxygen concn. of e.g. 1000 ppm, a very low CO content and forms no soot.
