Title: Warning device for hospitals - timer output coupled to monitoring unit to operate alarm and indicate bed or room
Inventor: SCHLENKER KARL
IPC: G08B5/22
Filed: 1975-01-03
Abstract: A timer controlled warning system for use in hospital wards enables an output to be generated at the end of a period that is transmitted to a central monitoring unit that indicates its location.

Title: Corrected numerically controlled tool - works in three axes from a fixed, automatic, error-corrector
Inventor: VOLKSTORF HANS-HERMANN DIPL IN
IPC: G05B19/401
Filed: 1975-01-21
Abstract: Machine tools programmed with nominal dimensions may in practive use off-size tools, but with manual corrective action later. A tool held in a spindle is set with setting plates and the measuring systems for X axis and for Z axis, to a defined position on the machine. With a nominal size tool the correction for both axes is zero, read by measuring elements. For an off-size tool the elements will read a displacement from zero, and an appropriate sign, feeds through inputs into a control. Together with the programmed commands a control issues the corrected feed commands automatically.

Title: Corrosion protection for pressed steel parts - with lubricating layer over protective layer to prevent scuffing
Inventor: FEICHTENBEINER HOLGER
IPC: B21D22/20
Filed: 1975-08-09
Abstract: The steel plate is coted with a corrosion inhibiting layer which is in turn protected by a lubricating layer. This protects the anti-corrosion layer, especially during pressing where scuffing can occur at the edges. The lubricating layer is designed to enable spot welds to be applied without prior removal of the layer. The corrosion inhibiting layer can be graphite or metal based to support welding, while the lubricating layer can be a thermoplastic film. This in punched through by the welding tool and flows back to protect the weld seams. The film can be designed to be the supporting layer for painting and thus requires no removal.

Title: Heat insulated tube for use in mine workings - haelectrically conductive outer surface connected to inner tube to prevent charge build-up
Inventor: PUTTER WARNER JAN DE
IPC: F16L59/12
Filed: 1975-11-21
Abstract: Heat insulated tube comprises inner (e.g. steel) and outer (e.g. PVC) tubes arranged concentrically with a heat insulating and resisting layer between them. The outer surface of the synthetic tube is coated with an electrically conductive layer (e.g. of thermosetting resin contg. C black).

Title: Water cooled HV cable with thermal insulation - has controlled temperature distribution related to thickness and resistance
Inventor: BRAKELMANN HEINRICH DR ING
IPC: H01B7/42
Filed: 1975-12-06
Abstract: A water cooled HV power cable has external thermal insulation. It consists of a conductor with a sealed channel conveying the cooling agent and electrical insulation surrounding the conductor. The radial temperature distribution in the cable insulation (4) is controlled so that there is a constant field strength along the entire length of the cable. The thickness of the insulation (8) and hence the thermal resistance along the length of the cable increases as the temperature of the cooling agent increases. The thermal resistance along the length of the cable is expressed in an equation involving specific thermal resistance of the electrical installation, ambient temperature, thermal resistance per unit length of electrical installation, thermal resistance of the corrosion protection of the cable and the temperature coefficient.

Title: Trenching plough for laying electrical cable - has slot produced in sidewall to receive warning tape and closed by in filling
Inventor: KAINDL JOHANN
IPC: H02G1/06
Filed: 1976-03-03
Abstract: The cable-laying plough lays both the cable and the tape that warns of the presence of a cable at the same time - ie in the same work process. The cable (4) is laid behind the cutting blade (1) through a chute (3). The warning tape is laid into a slot cut into the side of the trench some way above the cable and sloping either downwards to prevent the tape falling out or lying horizontally (in which case the tape is more likely to fall out). To prevent the tape falling out of its slot (of whichever inclination), a second blade (7) is located above the hollow blade (5) that cuts the slot and delivers the tape (6) into it. This second blade cuts away earth above the slot and presses it down into the slot on top of the tape.
