Title: Optical fibre protected against unauthorised tapping or coupling - uses stranded glass rovings in protective mantel which release tension to break optical core when cable is penetrated
Inventor: MAYR ERNST ING GRAD
IPC: G02B6/44
Filed: 1990-04-12
Abstract: The optical core (11) is located in a compact sheath (12) which is enclosed by a protective mantel (13).

Title: Quick-release clamping ring for grinding wheels -  has split nut allowing release of clamping force by moving two halves apart
Inventor: BINDIG BERND
IPC: B24B45/00
Filed: 1990-09-20

Title: Grinding non-circular contours of rotating workpieces - workpiece about carriage axis and computer controlling rotating grinding wheel
Inventor: BRAUNER WERNER
IPC: B24B19/12
Filed: 1990-10-16
Abstract: The workpiece and the grinding wheel can be moved relative to each other in at least one second X axis, at right angles to the first machine C axis. Positional data of the machine axes, representing selected points (guide points) of the workpiece contour to be produced, are stored as specified desired values in a machine control.

The machine control (12) has a control system (16) for storing the coordinates (CZn,XZn) of specified points (Pn) of the contour to be produced (guide points). An arrangement (17,21) determines successive desired values of axis positions which, between successive guide points, define a contour course at least near to the workpiece contour to be produced. A control unit (27,28) regulates the axis drive (6,9) according to the determined desired values (CS,XS). The processing arrangment (17,21) has a linear interpolator (26) for determining the feed increment. USE/ADVANTAGE - Grinding non-circular workpieces e.g. camshafts, using CNC grinders. Type improvement to give exact realisation of desired contour at large line speeds.

Patent DE-4037084-A1 (DE)
Inventor: BERTRAM VOLKER
IPC: A61M16/04
Filed: 1990-11-22
Abstract: An oropharyngal tube is used to obtain an artificial air passage after the introduction into the patient of a tracheal tube as a guide for a probe to extract secretions and a fixed holder is offered for the tracheal tube and the tongue is prevented from falling backwards. In addition, the tube is to serve as anti-bite protection for the tracheal tube. For this purpose artificial airways of the Berman type are known which have an open cross-section of T or double-T shape and basically consist of hard material. In order to provide an easily cleaned and manufactured oropharyngeal tube which can be used without risk, it is proposed that the tube be given a uniform U-shaped internal contour over its entire length which is open on one side and that the bite block be made in one piece with and of the same material as the tube in the region of the short straight section of said tube.
