Abstract: A fibre-optic gyroscope, or other apparatus for measuring phase modulation, has a source 1 of frequency modulated radiation which transmits radiation to opposite ends 5 and 7 of a coil 11 of optical fibre the length of which is one half wavelength. Radiation emerging from each end of the coil 11 is combined with reference radiation, derived by reflection from radiation supplied to the opposite end of the coil, and is supplied to respective homodyne detectors 21 and 31. The 3rd and 4th order harmonics are compared in amplitude to produce signals representing the phase shifts produced when the coil is rotated about its axis. After averaging in a comparator 40, a signal is derived representing rotation rate. <IMAGE>

Title: Method and arrangement for monitoring an electric line
IPC: H02H3/12
Filed: 1988-08-17
Abstract: In a method for monitoring an electric power supplied to an electrical heater, said power is generated by an electric current. The induction generated by the current is measured. When the induction falls below a predetermined limit value this is signalled as the failure of a power supply supplying the heater. The current is guided along a magnet and an induced voltage is measured and compared to the limit value. In the monitoring device a conductor through which an electric current flows runs along a magnet which has a winding which generates an induced voltage. The winding is connected to a measuring apparatus which measures the voltage and has a specific measured value display when a predetermined lower threshold value is reached. The specific measured value display is constructed as error display. The magnet is constructed as an annular magnet through whose opening, enclosed by it, the conductor runs.

Title: Telescopic-tube coupling, in particular for the suction tube of a vacuum cleaner
Inventor: BRINKHOFF HELMUT
IPC: A47L9/24
Filed: 1988-12-15
Abstract: The invention relates to a telescopic-tube coupling for a suction tube which comprises an inner tube and an outer tube, belongs to a vacuum cleaner and exhibits two spring clamping rings which are arranged one behind the other on the inner tube, which are operatively connected, in a rotationally fixed manner, to the outer tube and which can be adjusted in their clamping positions on the suction tube by an unlocking element with the effect of enlarging or reducing their internal diameter. In the case of said coupling, the invention provides an unlocking element which can move transversely with respect to the suction-tube axis and exerts an expansion action on the spring clamping rings which are connected in a rotationally fixed manner to the outer tube. The unlocking element engages over the inner tube with radial play, partially, and is clamped in between the spring clamping rings, retained by the spring force thereof. Such a measure provides a telescopic-tube coupling which can be easily operated and can be achieved on the telescopic tubes by simple means, without any great design measures.
Patent DE-3842636-A1 (DE)
Title: Method for checking components
Inventor: COEN GUENTHER DIPL PHYS DR RER
IPC: G06T7/00
Filed: 1988-12-18
Abstract: The invention relates to a method for checking components in production or in use for faults to be characterised according to type, magnitude, orientation and position, by means of graphical representation, a primary image being discretised upon entry to form image points of an original image, digitised in an AD conversion into grey levels and subjected thereafter to segmentation and to further processing up to the point of archiving in a data representation system. In order to be able to use such a method on any arbitrary image material serving for the quality control of components, and which is produced by material testing, both destructive and also non-destructive, the invention provides for the image points of the original image to be digitised by at least one bit more than can be reproduced by the data representation system and then, during segmentation, to separate out unimportant image regions with parameters, so that only the important image regions are processed in the data representation system. On the basis of previous examinations, an expert system is established which permits the faults to be detected and to be compared according to type, magnitude, orientation and position. If tolerable fault levels are exceeded, the component is renewed or action is taken in the production process until the cause of the fault is remedied.

IPC: B32B37/12
Filed: 1989-04-12
Abstract: A press sheet for use in a cold pressing of stacks of plaster board, chipboard panels with a cement or asbestos binder etc. is designed as a multilayer lamiante (1). A 4mm thick aluminium alloy sheet (A1Mg2.7Mn) is rinsed with organic  solvents in a solution of chlorinated hydrocarbons to remove stearate and other lubricants. After roughening by dipping in an etchingbath for 10 min. an epoxy resin adhesive (2) is applied to both sides at the rate of 80-100 g/m2.. Plates (3) of ultra-high molecular PE, 1.5mm thick, are bonded to both sides and left in a press at 120 deg.C and 10 bar for 10 min. Singeing of the PE plates before application helps the adhesion. ADVANTAGE - This produces press plates which never carry remnants of the plaster board panels and are resistant to the chemicals used in the process. This is a low-cost procedure.
