Title: Special matting for distance measurement in sports events - has conductors embedded in sheeting as coordinate grid matrix
Inventor: RABENSEIFNER KARL
IPC: G01D5/252
Filed: 1977-04-01
Abstract: The special matting for the digital electronic measurement of distance for sporting events, esp., shot-put or long jump, consists of a textile base layer, an elastic middle layer with perforations and an upper layer of highly stable textile material. Between the upper and base layers is a grid of electrical conductors, i.e. rows of wires crossing at right-angles but separated by the centre layer. The intersections are located precisely over the perforations in the insulating layer. The wires form an X-Y coordinate grid with metric intervals. When the shot or competitor's foot falls onto the surface, the intersecting wires are pressed together at that point and a circuit is made in the diode matrix. This is registered and the position displayed as a distance from the datum position.

Title: Heating system for buildings - uses heat pumps, supplied by buried heat store, with air heated in double solar pipes
Inventor: HANSCHMANN HORST
IPC: F24D11/02
Filed: 1977-06-03
Abstract: The unit supplies buildings with energy and uses heat pumps, heat stores, and solar cells. Heat pumps contg. two pistons with armatures supply current synchronously to the armatures and to coils around the cylinders, via two guide rods with sliding contacts, which project from the cylinder ends. Piston acceleration produces high pressures in the compression chamber. Alternately, the pump may have a semi-circular tube with two end cylinders, and a piston, which is connected to a shaft via a metal arm. The arm supplies current to the piston armature. The shaft carries a disc connected via a rod to the flywheel of an electric motor. The pump is supplied with warm air from heat store, which is ca. 5m below ground level and consists of stones with heating-and draught channels, and has a heat-insulating brick cladding. The air in the store is heated by a system of solar pipes in the garden, consisting of double plastics pipe with intermediate air space, the inner pipe having a dark lower side.

Title: Decarburising high carbon contg. magnetic conductor sheet - by heating, recrystallisation and oxidn. cooling in protective gas atmos. having controlled moisture content
Inventor: VASILEV SERGEJ ZINOVEVITSCH
IPC: C21D3/04
Filed: 1977-12-27
Abstract: Magnetic conductor sheets having a high C content are heated >750 degrees C in a protective gas atmos., long enough to remove C excess and form the desired ferrite grain size, and then cooled to complete recrystallisation. Cooling is continued to form an oxide layer on magnetic conductor sheet surface. Novelty consists in using a protective gas atmos. contg. 2% CO, 1.5-4% H2, balance, to 100% N2. Moisture content in protective gas atmos. corresponds to dew point 7-10 degrees C during heating, 30-40 degrees C while holding >750 degrees C and during re-crystallisation cooling and 70-80 degrees C during oxidn. cooling. The sheets are used in electrical machinery and instruments. Treatment can be carried out economically in a simple continuous heating furnace. Explosion hazards are excluded.

Patent DE-2808546-A1 (DE)
Inventor: OGIU HISAO
IPC: A61B18/14
Filed: 1978-02-25
Abstract: A high frequency electrosurgical instrument for cutting human body cavity structures comprises a sheath made of an electrically insulating material and a metal wire. The metal wire consists of an operating wire portion reciprocating through the sheath and a cutting wire portion folded back toward the sheath at the end of the operating wire portion extended from the distal end of the sheath. The end of the cutting wire portion which is remote from the end of the operating wire portion is held by the sheath and at least the part of the operating wire portion extensible from the distal end is covered with an electrically insulating wrapping member. After the distal end portion of the sheath of the instrument is conducted through the channel in an endoscope at human body cavity structures, the operating wire portion is extended from the distal end of the sheath and its extended portion is pulled by the cutting wire and curved so that the extended end portion of the wrapping member abuts against the inner wall of the human cavity and prevents other structures than those to be cut from being damaged by the cutting wire portion.

Title: Aq. dispersion contg. polymer with epoxy and hydrolysed epoxy gps. - used in photographic coating compsn., avoiding agglomeration and curling
Inventor: ISHIHARA MASAO
IPC: G03C1/04
Filed: 1978-04-11
Abstract: Aq. dispersion contains polymer granules with or of a polymer with epoxy gps. and dihydroxy gps. derived from the hydrolysis of epoxy gps. The polymer pref. contains recurring units of the formulae -CHR2 CR2-A-B (in which B is (1) -CH-CH2 and (2) -CH(OH)-CH2OH). R1 is H or a short-chain (1-2C)alkyl gp. R2 is R1 or halogen. A is a divalent organic gp., pref. alkylene, (alkylene)oxyalkylene (di)carbonyloxyalkylene, carbonitrilo(oxyalkylene) or carbonyl-amino). The claims cover the use of the dispersion as photographic coating compsn. It can be used in both insensitive and photosensitive layers. Unlike other aq. dispersions, it can be mixed with hydrophillic colloids (gelatin) and treated with hydrophobic (photographic) substances. If organic solvents are present, they do not cause agglomeration of the polymer. The dispersion is stable and does not lead to staining through interaction with a colour developer or discolouration of the developed image. There is no redn. in speed or increase in fog and the coated photographic base has better dimensional stability and curling properties and much better scratch and pressure resistance flexibility and drying.
