Title: Concentration of encrusting liquids salt water or effluent - by mixing with liquid possessing higher affinity for tube surfaces
Inventor: HOECK HORST DIPL ING
IPC: C02F1/10
Filed: 1973-09-15
Abstract: A method of evaporating a crust-forming or corrosive solution at given pressures and temps. consists of mixing the soln. with a heat transfer liquid which does not boil at these pressures and temps; the heat of the mixt. is utilised for evaporating the soln, the gas expanding at the soln. boiling pressure, and a portion of the heat of condensation is recovered and utilised in a number of heat exchangers for pre-heating the mixt. This recovered condensation heat is transferred through metal heat exchange surfaces, the heat transfer liq. utilised possesses a higher affinity for these metal heat exchange surfaces than the soln, and the mixt. is of such a proportion that the ratio of heat transfer liquid/solution is sufficiently large for the former to constitute the closed phase and the latter the dispersed phase. Pref., in a multi-stage system, this ratio in a given stage is smaller than the ratio of the hotter mixt. supplied to this stage and generating the heat of evaporation. The pref. liquids used are mineral, plant or animal oil, waste oil, synthetic oil, high-boiling organic liquid, dilute waste acids or mixtures of these.

Patent DE-2362351-A1 (DE)
Title: Tobacco pouch made from laminated rectangular foil - has welded seams of unequal tear strength
Inventor: CANTOR ROBERT PETER JACOB
IPC: B65D75/20
Filed: 1973-12-14
Abstract: One layer of a laminated foil is a thermoplastic which is suitable for welding. A rectangular blank made from this foil is folded so that about two thirds of it are overlapping. The two edges are then welded so that a pocket is obtained which is filled with a measured amount of tobacco. The filler slot is then sealed by applying a known heat source for a certain time and with a given pressure until a welding seam is obtained. By reducing any one of the three variables, a welding seam of reduced tear strength is obtained, hence when the pouch is torn open, the two seams on the sides are not damaged.

Patent DE-2443018-A1 (DE)
Title: Fuel element for liquid metal cooled fast reactor - has helical multistrand wire spacer permitting elements to expand
Inventor: KURILKIN WITALY WITALIEWITSCH
IPC: G21C3/338
Filed: 1974-09-09
Abstract: A nuclear reactor fuel element cluster has spacers between the elements in the form of a helical wire wound around each (or some) of the fuel elements so that it is in contact at certain points with adjacent elements. Each helical wire is accompanied by at least two additional wires, so that a twisted spacer, constituted of at least three wires is helically wound around the fuel element over its entire length; all the wires are stiffly connected together in the spaces between the contact planes. The cluster is used esp. in a liq. metal-cooled fast reactor. The use of a twisted "cable" around the fuel elements provides a resilient spacer, by contrast with a single helical wire; it is thus possible for the spacers to accommodate the expansion of the elements which takes place, so that the fuel life in the reactor is thereby increased.

Title: Railway track rail fixture - with screw anchored in expanded substructure hole by encompassing elastic spreader plug
Inventor: KRACKE HARALD
IPC: F16B13/14
Filed: 1974-09-26
Abstract: The rail fixture system is as applied on wooden or concrete sleepers, as well as in connection with superstructures where there is no ballast, with screws turned into the wooden sleeper or into a wood and plastic dowel plug, fixing underlay plates and/or clamping plates on the sleeper. The screw (14), or its shaft, is anchored in an expanded hole (17), in the sleeper by means of a spreader dowel plug (18), made of thermoplastic rubber or polyester elastomers etc, which encompasses the screw and is pressed against the walling of the hole. The dowel plug may be inserted into the expanded holes with an outer coating of adhesive, and may have external projections to increase friction on the surface. The screws can be reverse-turned later without harm, and sleeper cleaning can be carried out on a damp and/or oily base and at low temperatures.

Title: Vehicle friction clutch operation - uses centrally located ball bearing to produce axial load from external source
Inventor: MAUCHER PAUL DIPL ING
IPC: F16D13/70
Filed: 1975-01-31
Abstract: The friction clutch for vehicles is located inside a flat and round housing body. A centrally located ball bearing transmits the external operating force axially onto the clutch friction plates. The outer bearing ring is radially held by leaf springs and secured against rotation by a lug of the pressure plate. The inner bearing ring is used to locate the external clutch operating element which applies the axial force. The clutch operation occurs thus in an axial clutch direction which prevents radial or rotational deviation.

Title: Power unit with energy storage booster - two ratio epicyclic gear train to connect engine and motor generator to wheels
Inventor: KOERNER HELMUT
IPC: B60W20/00
Filed: 1975-02-06
Abstract: The vehicle transmission is fitted with a two ratio epicyclic gear train with two sets of planet wheels, and two sun wheels. An engine drives the gear train and through it the wheels and/or the generator/motor to store energy in the energy store i.e. battery. If extra torque is required then the generator/motor is driven by the energy store to add its thrust to the wheels via one of the sun wheels. The gearbox is simple and compact and replaces the complex and expensive torque converter of conventional systems. A low powered engine can thus be fitted to the vehicle for economic running costs.

Patent DE-2518046-A1 (DE)
Title: Heat reflecting coating for roller shutters - is applied as adhesive bonded foil or plating or lacquer layer
Inventor: EISENSCHINK ALFRED
IPC: E06B9/17
Filed: 1975-04-23
Abstract: The coating for the inner face of roller shutters is used for reflecting heat radiation through the window. This coating is applied on the inner surface of the roller shutter made from thermally insulating material such as timber of plastics. This coating improves thermal insulation properties of such roller shutters because a great deal of internal heat of the room is reflected back into the room. The reflecting layer can be made from a metal foil which is welded or adhesive bonded to the shutter ribs. The reflecting layer can also be a metallised plastics material or alternatively the reflecting layer can be electroplated or vapour deposited on ribs. Other methods can also be used such as metallic lacquers or continuous adhesive bonded reflecting sheets.
