Patent DE-2809287-A1 (DE)
Title: Fail=safe monitor for two signal valves - monitors signals from main and redundant channels and triggers alarm when different
Inventor: BOHMS HERBERT
IPC: H02H3/26
Filed: 1978-03-01
Abstract: The monitor, for redundant systems secured against component failure, is made fail-safe by superimposing a rectagular-wave voltage on the error signal formed as the difference between the signals in the two channels being monitored. The rectangular voltage drives two triggers associated one with each channel. The triggers drive a transistor bridge whose a.c. diagonal contains a transformer supplying two relays each with two sets of change-over contacts. The bridge's d.c.diagonal contains a d.c. source connected via two sets of change-over contacts belonging to different relays.

Title: Power line distribution support for moving load - has tubular links with halves of wide links shortened by width of groove between narrow link stops
Inventor: MORITZ WERNER
IPC: H02G11/00
Filed: 1978-12-13
Abstract: In order to improve the self-supporting properties of the power line carrier the series of interengaging and mutually bendable tubular links are provided alternately in wide and narrow shape. The wide lines have inwards directed stops, while the narrow ones have the stops directed outwards. Each wide link is shortened in the region of its cross-sectional half by the width of a groove between stops of narrow links. A link half (8') of each wide link (B') is thus shortened by the width of a groove (4) between stops (2, 3) of each narrow link (A'). The connection between the two link halves (7', 8') lies in the region of neutral threads (23) of both links. Preferably the link halves overlap in the junctions, the wider halves engaging the protrusions of the narrow link half. The two link halves are joined by expansible rivet (25), screwed together (28), or spot-welded (29). Snap connection (30) may be also used.

Title: Optical identification system for cut diamond - uses reflected light and has optical fibre illumination and receiver system in contact with stone
Inventor: ALDINGER ULRICH
IPC: G01N21/87
Filed: 1979-04-19
Abstract: The device uses quantitative reflection measurement to identify cut diamonds and is improved w.r.t. similar devices so that it can identify round cut diamonds and stones of any size. The light from the source is passed via an optical system in contact with the stone. The optical system consists of a lens attached to the end of a glass fibre light conducting system. The wavelength of the light lies between ultraviolet and infra red. The light is fed into the optical system in a series of light pulses. The receiver system contains an electronic circuit which records the maximum value measured during each measurement cycle. The technique ensures complete transfer of illumination and reflected light to and from the stone irrespective of its size or shape.

Title: Forming boxes from hard PVC blanks - in automatic machine with folding blades and jaws with ultrasonic welding tools
Inventor: ZITT VOLKER
IPC: B29C65/08
Filed: 1979-05-25
Abstract: The jaws of a tool for the production of boxes from hard PVC in the form of pretreated blanks, has ultrasonic wave generators for the welding of the overlapping surfaces, whilst the punch acts as the anvil for the ultrasonic welding. In addition to the punch, the tool has folders which set up the overlappings for pressing against the punch by the jaws. In the welding zones of the punch, the surface is raised esp. along the edges of the blank, which cover a small part of the overlapping surfaces. A device is provided which carries out the whole operation of folding and welding automatically from the presentation of the blank to the ejection of the finished box. The raised zones reduce the welding energy required and spot welding only may be used without weakening the boxes. Deep boxes are produced by a telescopic punch.

Title: Electronic time delay switch for battery operated electrocardioscope - has ECG signal passed to trigger switch directly after operation of start button
Inventor: DEHNERT HEINZ
IPC: H02J9/00
Filed: 1980-09-09
Abstract: The switch for a battery-operated electrocardioscope allows the current supply to be switched on upon operation of a start button and causes the supply to be subsequently disconnected after the given time delays determined by the charge time of an RC element. The time delay switch is brought into the active state directly after operation of the start button via a trigger circuit which is triggered by the ECG signal. The time delay switch comprises a flip-flop which changes state upon operation of the start button to control a relay for obtaining closure of the supply switch. A capacitor is charged via a resistor after switch closure and its voltage is compared with that provided by a voltage divider to provide an output signal for returning the flip-flop to the original state with the supply switch subsequently opened.

Title: Electrode for high-pressure discharge lamp - has wire bent back and wound in helix around itself
Inventor: BEGEMANN JUERGEN
IPC: H01J61/073
Filed: 1980-09-29
Abstract: The electrode, for a mercury vapour lamp, consists of a wire looped back on itself with one end wound helically around the other. The wire may be wound a second time helically around its first helix but in the opposite sense. The unwound end (6) of the wire projects out of the helix or helices. The advantage lies in compactness and rigidity even when the wire is small in diameter. The electrode is also cheap and easy to make, is mfd. from a high m.p. metal and has a low discharge current flow, for example 1 amp.
