Patent DE-2330714-A1 (DE)
Title: Stone dust discharge mechanism for underground mines - has local dispersing valves operated electrically
Inventor: KUEHME JUN ERNST
IPC: E21F5/20
Filed: 1973-06-16
Abstract: The pipelines carrying the stone-duct along the mine roadways incorporate sliding valves at regular intervals from which the dust can be dispersed locally. The operation of these valves by hydraulic or pneumatic methods is inefficient. Operation of these valves using an electric motor is described. The through-tube or the branch-tube with outlet is sealed over the flowline inside the valve by a gasket and spring. The motor, when placed on the side casing of the valve, positions the appropriate tube directly through an adjusting spindle, but if placed above the valve operates the spindle through a system of linked rods. The branch tube has a rubber nozzle to aid dispersion of the dust.

Title: Oil power cable with water cooling - uses axial grooves in layer above sheathing for high pressure water
Inventor: RISO HANS DIPL ING
IPC: H01B7/42
Filed: 1973-09-07
Abstract: The oil cable consists of a tubular sectionalised conductor as cooling oil passage surrounded by an oil impregnated insulating layer connected to an oil channel and covered by a screening foil, sheathing and protective sheathing. Between sheathing and protective sheathing are cooling channels to convey water under high pressure. Between sheathing the protective sheathing and the cooling channels containing layer a pressure protection is provided by glass fibres wound in short-lay turns around the cable. The cooling channels can be realised by forcing onto the sheathing an intermediate layer of synthetic material such as PVC with continuous grooves in cable axis direction and near the sheathing. The protective sheathing may be designed weaker due to the provided pressure protection layer. The cable may be loaded to full capacity without emersion into a water cooling tube.

Title: Tubular plastics wrapper for rectangular objects - has reinforced integral carrying handle consisting of four layers of plastics foil
Inventor: WERNERSEN ERIK
IPC: B65B61/14
Filed: 1973-11-19
Abstract: Plastics foils from two reels are used to produce an open tubular container. This is done by pushing the rectangular objects which have to be packed together with the foil into a forming chamber. The container is then bonded or welded and separated from the foil supply. One end of the container remains open with its foil overlap folded inwards. At the next stage of the packing, a sealing weld closes the container and retains the folds in their position. A hole is then punched into the strip thus forming a carrying handle which consists of four layers of plastics foil.

Title: Plastics sheet esp. for bag making - transversely cut at high speed by rotor-mounted tools accompanying sheet motion
Inventor: KOHLS SIEGHARD
IPC: B26D5/26
Filed: 1974-03-22
Abstract: An appts. for transversely cutting a continuously moving sheet of material which can be welded, esp. plastics, is used for cutting the sheet at predetermined intervals of time into predetermined lengths. A number of cutting tools are mounted at specific angular intervals around a common axis; the path of the continuously moving sheet of plastics or the like is tangential of the paths of these cutting tools; the tools are normally stationary but when a sensing device mounted upstream of them relative to the direction of travel of the sheet, is actuated, this starts up the rotational motion of the cutting tools so that a cut is carried out. Pref. there are two parallel axes with sets of cutting tools rotating about them and mutually co-operating in pairs acting from opposite sides of the sheet to be cut. The motion of these two sets of tools is provided by a clutch or a gear drive actuated by the sensor. The sheet of material can be fed at high speed; its movement does need to be stopped for cutting, sinc the tools accompany its forward travel and are rapidly set in motion by rotation of their supporting wheels or discs.

Title: High temp lubricants for hot-forming of metals - contg borate-phosphate melts, solid lubricant and decomposable organic substance
Inventor: DORN KARLHEINZ DR RER NAT
IPC: C10M169/00
Filed: 1974-06-24
Abstract: High-temp. lubricants based on mixts. of (A) a melt product of phosphates and borates of alkali, alkaline earth or heavy metals and (B) lubrication-improving additives e.g. ZnS, CaF2, NaF, graphite, NaCl or Na-Zn polyphosphate, with addn. of (C) an organic product based on cellulose, starch, synthetic resin or mixts., which decomposes spontaneously on heating with evolution of gas and without residue. The lubricants are used in the hot-forming of metals by extrusion, casting, forging or impact. Addn. of (C) gives a substantial improvement in lubricating properties by forming a gas film between tool and metal part, which does not interfere with the melt layer. Useful life of forming tools is extended. The shaped metal parts do not require subsequent etching with HF, as when silicate glass lubricants are used.

Title: Bottom roll alignment - by lifting devices beside stands with shims carried sideways by drive OGS
Inventor: BOHNENKAMP HEINRICH
IPC: B21B31/22
Filed: 1975-05-09
Abstract: The top edge of the bottom work roll of rolling mills such as four-high rolling mills can be adjusted to the desired roll line by shims. The extracted roll can be adjusted to the roll line by worm-gear operated lifting screws which raise the extraction slide with the roll housings. Shims between the bottom of the slide and protruding above the top of the lifting screw table are then carried away by drive dogs when the new roll is returned into the stand. This introduces any required shims without manual labour. No other lifting tackle is required and no time is wasted.
