Patent DE-2525268-A1 (DE)
Title: Inert gas feed for inductive tube seam welds - injecting deep cooled argon on weld and baffling entrained air
Inventor: FLIEGENSCHMIDT EBERHARD DIPL I
IPC: B23K11/00
Filed: 1975-06-05
Abstract: A homogeneous inert gas atmosphere is introduced to the area of the welding point during the longitudinal or spiral seam welding of tubes. A liquefied inert gas, cooled to -200 degrees C, is directed under pressure directly to the welding spot where it is gasified and heated. The air column entrained by the moving tube is restrained by a baffle plate which is fixed on the same mandrel as the impeder. The immediate gasification of the liquefied gas on contact with the hot flanks of the weld results in an 850-times magnification of the volume and a complete displacement of the ambient air. This system is equally well suited to longitudinal and spiral seam welding of tubes where a homogeneous protective gas atmos. is required. The baffle plate stabilizes the gas conditions.

Title: Moulded packing paper sheets - mfd from dry waste paper reduced to fibres for matting to be embossed
Inventor: MINAKUCHI KAZUO
IPC: B65D81/127
Filed: 1975-07-09
Abstract: In the mfr. of padded sheeting material, to act as packing for the transport of merchandise to aborb the stresses of handling and protect the goods, dry waste paper is reduced to fibres and dispersed by air to form a matting by suction on a wire netting support which is then pressed together by embossing rollers to give a relief surface structure to the moulded sheeting. The use of dry paper, without any water, gives a sheeting with good elasticity and spring, with good shock absorbent properties, using waste material which would otherwise be discarded.

Title: Power supply for beacon buoy - uses wave motion to generate electrical power by induction caused by relative motion of two spheres
Inventor: WINKLER HERMANN
IPC: B63H19/02
Filed: 1975-12-02
Abstract: The beacon buoy is lowered by wave motion. The electrical generator takes the form of a sphere carrying a winding, with a further internal sphere, incorporating an eccentric mass, carrying the field. Wave motion in any direction causes relative motion between spheres, and a current is generated in the winding. The current is used to charge a battery which, in turn, supplies power to the beacon light on the buoy. The electric power supply is environmentally more desirable than gas.

Title: Underground sectioned pipe pressing unit - with limited swivelling for hydraulic pressure plates with curved abutment faces
Inventor: PLESTER KARL-HEINZ
IPC: E21D9/06
Filed: 1976-05-06
Abstract: The forward thrusting press mounting is esp. for intermediate positions for forwarding underground lengths of pipe, moved along in sections, using double-action piston and cylinder units. The pressure plates for piston rod head and cylinder base (15) have similarly curved abutment faces (13, 16) on both sides, and are held so as to permit limited swing between pressure bearing surfaces rigidly joined to this head and base. Their swing is limited by the conical configuration of a plate recess (23) providing passage for the fixing screw whose head (18) underside forms the second press bearing surface. This enables individual presses to effect exactly parallel pipe alignment regardless of radius of any curve being neogitated.

Title: Discharge valve for multicylinder reciprocating pump - has individual ball valves spring loaded round circumference of plate
Inventor: HAMMA KARLMANN
IPC: F04B53/10
Filed: 1976-07-21
Abstract: Each cylinder of a pump has a discharge passage (2) into a valve plate (5). A short radial passage meeting this leads to an opening (9) in the circumference of the plate. An outer channel (3) round the plate links all the openings to a common discharge pipe (4).
