Patent DE-2640840-A1 (DE)
Title: Automatic coupling for tractor attachments - with hydraulic connections operated by cams linked to coupling lever
Inventor: HOLMQVIST BO
IPC: E02F3/36
Filed: 1976-09-10
Abstract: The tractor is fitted with an automatic coupling for working tools, operated by a ram (16). This operates a locking lever (12) to grip and secure the mounting frame of the tools. The ram action also operates a cam lever (56) which presses a hydraulic connection (29a) into a similar fitting (26b) on the attachment. The hydraulic couplings are self locating and enable any working attachment to be coupled to the tractor in one automatic operation and without the driver leaving the cab. The uncoupling of the tools is also automatic, with non-return valves sealing the ends of the hydraulic lines.

Title: Reels of adhesive foam tape with improved reel integrity - are coated on one face with a layer of film forming material
Inventor: VITEK ROBERT DIPL ING
IPC: C09J7/26
Filed: 1976-10-28
Abstract: Reeled foam tapes, esp. self adhesive sealing tapes, are provided on >=1 face with a layer of film forming material esp. a lacquer or a hardened adhesive. Suitable film-forming materials are e.g. lacquers based on vinyl polymers, chlorobutyl rubber, nitrocellulose, cellulose esters, cellulose ethers, etc., spirit lacquers, alkyd resins, two component adhesives, epoxy resins, etc. The film-forming material is applied to the reel of foam, e.g. in the form of a stripe extending through the middle of the reel. The process is esp. useful with draught excluder type self adhesive foam tapes, which are generally provided with a siliconised paper release strip covering the adhesive layer. These tapes are sold in the form of reels of the tape in various lengths. After reeling, the free end of the tape is joined down and the reel is packed in a suitable bag or blister pack. The application of a film forming material to the face of the reel allows lengths of tape to be removed from the reel without the reel losing its integrity, while it is also possible to use cheaper forms of packaging of the reel.

Title: Erecting draped curtains - ensuring that pleats of centre curved section hang correctly without distorting appearance
IPC: A47H13/14
Filed: 1976-12-18
Abstract: In erecting draped curtains, a central upper curved section hangs in a curve between two side drapes. The pleats of the central curved section are fixed by a gusset from the upper edge. The pleats are laid round the gussets so that the upper ends of the pleats form points ranging over the upper edge, and along it, to be quilted on the path of the centre curve. The system ensures that the pleats of the centre curved section hang correctly, and do not drag ad distort the appearance of the draping. The pleats of the centre curved section are laid on or next to the gusset. The projecting points of the pleats are cut where they range over the upper edge of the centre curved section. The laid pleats are wholly or partially stitched together with the upper ends of the curtain's side drapes in the quilted seam zone of the curved centre section.

Patent DE-2716721-A1 (DE)
Inventor: MAUREDER ENGELBERT
IPC: D06F58/18
Filed: 1977-04-06
Abstract: The disadvantage of known washing/drying machines, that, after the wash, the laundry cannot be dried in the same drum in one operation, is overcome by the apparatus according to the invention, since, in this apparatus, the heat radiators (28) radiate their heat rays (S) directly into the entire drum interior, the heat radiation being assisted by hot air blown into the drum by means of a blower. Heat radiation, convection and heat conduction bring about a rapid drying of the entire laundry batch. For drying purposes, the moist air can be guided via a cooling surface (78), which can be the limiting surface of an evaporator (37) of a refrigerator, and be sucked up by the said blower via the funnel (111) and used again for drying. During the washing process, the washing fluid is conveyed in circulation through the interior of the drum (5) via a funnel (32) by means of a pump (63), and the heat radiators (28) simultaneously radiate into the drum interior. In the same way as the drying process, the washing process is also accelerated as a result of the interaction of heat radiation, convection and heat conduction. <IMAGE>

Title: Compressed air reservoir for motor vehicle - has two extruded aluminium alloy pots welded together whilst centred on mandrels
Inventor: HAGEN HANS DR ING
IPC: B21D51/24
Filed: 1977-05-04
Abstract: The air pressure vessels with defferent capacity, has pots made with the same dia. Two pots are welded together via a peripheral seam to produce a vessel. The pots are made by extrusion, using a mandrel to form a connection hole in the base of each pot. The mandrel has an external thread so that an internal thread is formed simultaneously in the connection hole during the extrusion process. The pots are pref. made by extruding a disc blank contg. a central hole which fits over the mandrel. The ram (4) is driven in direction (x) along the die axis (2) so that the blank (17) assumes the shape of the die cavity (7) and also forms an internal thread. The mandrel (5, 16, 15) is then unscrewed out of the threaded connection hole. By making pots of two different lengths, three sizes of reservoir can be obtained.

Title: Exhaust gas feedback for gas turbines - has feedback rate determined by combination of air compressor intake and turbine intake temp.
Inventor: EARNEST ERNEST ROBERT
IPC: F02C1/00
Filed: 1977-07-12
Abstract: Heat from the turbine exhaust gases is used in a heat exchange system (28) to vapourise an organic working medium, which is then used to drive a closed cycle turbine (34). Part of the exhaust gas is extracted after it has left the heat exchanger, from the exhaust pipe (30) and fed to a mixing valve (16). The mixing valve (16) is located upstream to the compressor (14) and returns some of the turbine exhaust gas corresponding to signals received from a regulator unit (58) which receives environment dependent temp. signals (60) the gas mixture temp. at compressor inlet (62) as well as the turbine inlet temp (52). The regulator logic circuit works on the basic difference between the gas mixture temp. and air intake temp. (62, 60) independent from the turbine inlet temp. (52).

Title: Radioactive fuel embedded in solidified salts mixt. in container - for storage and transport as compact unit requiring no cooling pool
Inventor: VOX ANTON J
IPC: G21C19/32
Filed: 1978-01-18
Abstract: A method of removing fuel elements from a nuclear reactor and preparing them for transport away from the reactor consists of lifting the elements out of the reactor by an overhead crane or the like and placing them in a container which is filled with liquid salt or salts mixture; the salt or salts mixture is then cooled to solidify it and embed the fuel elements. Pref. the container is placed along-side the reactor, the elements are lifted out into a temporary shield or bell and then lowered into the container, the salt of salts mixture being introduced either before or after the elements. The elements can be temporarily stored and transported and the use of a cooling pool is not required since the salts mixture provides adequate heat conduction and dissipation.
