Title: Activator for cell tissue of living creature - uses synthetic fibre fabric with in-woven carbon fibres preventing build up of negative potentials in body
Inventor: POPPE ULRICH DIPL ING
IPC: A61N1/14
Filed: 1976-04-30
Abstract: Activator for cell tissue of living creature comprises a planar structure e.g. a synthetic fibre fabric with in-woven carbon fibres, and pref. with in-woven fibres of semi-conductor material. The structure is to be contacted with the surface of the cell tissue, and has an electrical work function greater than that of the body of the tissue to be activated. Articles of clothing made with this fabric prevent the build-up of negative and therefore harmful potentials in the body, so that O2 in the circulation can perform its function without obstruction. Carbon fibres have greater tensile strength than metal threads, and are therefore easier to weave in and maintain the desired properties even after prolonged usage.

Title: Butt welding metal pipes - using internal and external ceramic rings to prevent bulges or flash at the joint
Inventor: ECKARDT PETER DIPL CHEM DR
IPC: B23K11/04
Filed: 1976-07-23
Abstract: Hollow metal profiles, esp. tubes or pipes, are butt welded by heating the entire periphery of the mating ends and pressing the two tubes together. Before welding, a hollow liner or cup, which does not bond to the tubes, is placed inside the tubes at the joint surface; and the outside dia. of the cup is slightly smaller than the bore of the two tubes being welded. During the welding process, the cup is continuously moved slowly along the bore of the tubes by means of a cable pulling the cup axially in the bore. A ring which does not react with the metal tubes is pref. located on the outside of the butt joint, the bore of the ring being slightly larger than the outside dia. of the tubes. For the welding of pipe elbows, the cup is pref. assembled from three or more segments, or is grooved so it can easily be fractured after welding.

Title: Water-dispersed, alkyd amino resin coating compsns. - contg. reactive surfactant prepd. by addn. of ethylene oxide and/or glycidol to long chain guanamine cpds.
Inventor: ESCHWEY HELMUT DIPL CHEM DR
IPC: C08G63/48
Filed: 1977-03-14

Patent DE-2718019-A1 (DE)
Title: Equate operand address space control system - provides control over processor addressabilities selectable in main memory of data processing system
Inventor: BIRNEY RICHARD EUGENE
IPC: G06F12/06
Filed: 1977-04-22
Abstract: The equate operand spaces (EOS) system provides control over the addressabilities accessed by means of different address keys in an address key register (AKR) in a processor. Executing instructions, and their source and sink type operands may have different address keys in the AKR and therefore different addressibilities. When enabled, the EOS control forces each source operand fetch to occur within the sink operand addressability specified in the AKR, even though the AKR explicity contains a different addressability for source operands. When the EOS feature is disabled, the source operand addressability contained in the AKR is used when fetching source operands. An EOS field in the AKr stores whether the EOS state is enabled or disabled in the processor.

Title: Convertible chair bed with interfitting base frames - has slightly stepped dimensions of frame elements for easy sliding in and out
Inventor: ZIMMERMANN RICHARD
IPC: A47C17/13
Filed: 1977-05-14
Abstract: The chair unit has several U-shaped frame elements (11) whose height, depth and width are suitably graded to rest within each other when folded. The frame elements have side parts (12, 12') which form the vertical U-arms of the frame and slide on the ground where they contact each other to form a longitudinal guide. They have horizontal slats (16) forming the horizontal U-web of the frame. The falt part of each element is offset in height relative to the other. The inner ends of the side parts, seen from the extension direction, have guide stops (18) which project beyond the limits of their own U-section and into the area of the adjoining U-section of the folowing frame element. When the frame is converted from a bed support to a chair support there is still adequate storage space beneath the chair.

Title: Hanging tiles for suspended furnace roofs - having several projecting ledges between a corresp. number of bridging tiles
Inventor: WURDITS PETER
IPC: F27D1/02
Filed: 1977-07-06
Abstract: Hollow suspended roofs for industrial furnaces use clamp shaped hanging tiles made from refractory material. These are mounted on parallel carrier bars. Refractory roof tiles are then suspended between the hanging tiles at right angles to the carrier bars, held by a support ledge whih forms the foot of the hanging tile. A further support ledge is located above the foot and a second layer of tiles can then be supported by this. The hanging tile can have two such support ledges above the foot. The head of the tile widens out and slots into hanging bracket attached via hook to the carrier bars. Method allows furnace roof tiles of a simple pattern to be used with several layers of them, reducing the cost and allowing the tiles direct mounting to the carrier bags.
