Patent DE-3719399-A1 (DE)
Title: Device for operating a friction clutch disengageable counter to a spring force
Inventor: REINECKE ERICH DIPL ING
IPC: F16D13/75
Filed: 1987-06-11
Abstract: Due to the construction of a friction clutch engageable by spring force, the position of the release element (4) of the friction clutch changes relative to the transmission mechanism (5, 9) in engagement with the release element (4) as the friction lining wears. Compensation of the wear of the lining or maintenance of the engagement conditions of the friction clutch can be achieved, for example, by changing the length of the transmission mechanism (5, 9) or by changing the distance between the actuating device (1, 5, 9) and the release element (4). The compensation of the wear of the lining is achieved by means of an automatic change in the length of the transmission mechanism (5, 9) while maintaining a constant pressure-chamber volume (3) of the device during the entire service life. The automatic change in length is achieved by means of a silent ratchet (friction ratchet mechanism) (11, 12, 13) which is integrated into the transmission mechanism (5, 9), can compensate for relatively large installation tolerances and permits a relatively short overall length of the actuating device (1, 5, 9). The device is particularly suitable for operation by compressed air. <IMAGE>

Title: Shedding device for textile machines, especially weaving machines
Inventor: SCHLEICHER OSKAR
IPC: D03C3/20
Filed: 1987-07-25
Abstract: In a shedding device for textile machines, especially weaving machines, with lifting elements moving in opposition and with holding magnets acting on the lifting elements and controllable via program carriers, and with armatures provided between the holding magnets and the lifting elements, provision is made for assigning to each of the armatures a mechanical retention device which acts automatically under an effective holding force exerted by the associated magnets and which retains the armature against the magnet, and for the armatures to be exposed to a prestressing force directed in opposition to the magnetic force. The holding effect is achieved essentially by means of the mechanical retention device. The magnetic force need only be so high that it is higher than the prestressing force acting on the respective armature.

Title: Acceleration sensor
Inventor: SONDERGELD MANFRED DIPL PHYS D
IPC: G01P15/08
Filed: 1987-12-12
Abstract: An acceleration sensor has a contact-mass system (15, 18). When a predetermined acceleration threshold value is exceeded, an electrical signal is generated by an acceleration-dependent deflection of a seismic mass (18). To generate a dead-time free signal with a defined response point without resonance phenomena and having the possibility for long-term monitoring and functional testing, the seismic mass (18) is arranged on a flexible contact element (15) of an electrical switch. The flexible contact element (15) lies on a further contact element (13) under a magnetically generated pretension. The seismic mass (18) and the pretension are so dimensioned that, if the acceleration threshold value is exceeded, the contact elements (13, 15) are raised away from each other (Fig. 1). <IMAGE>

Title: Process for recovering carbon monoxide
Inventor: SCHMID WOLFGANG DIPL ING
IPC: C01B32/40
Filed: 1988-04-28
Abstract: A process for recovering CO from a H2/CO crude gas mixture is carried out in two process steps:   (a) The crude gas mixture is partially condensed and subjected to nitrogen scrubbing, which forms an H2-rich and a CO-rich fraction. (b) The CO-rich fraction is fed into an H2 stripper, from the bottom of which the CO product is drawn off.   As a result of low consumption of scrubbing nitrogen in (a), the CO product purity in (b) is high. The H2-rich fraction from (a) can, enriched with N2, be fed to an NH3 synthesis. <IMAGE>

Patent DE-3822138-A1 (DE)
Title: Liquid-level monitoring
Inventor: TELFORD DAVID WILLIAM
IPC: G01F23/296
Filed: 1988-06-30
Abstract: Ultrasonic Lamb waves are input into a metal plate (10) of thin cross-section, which extends generally perpendicularly above the content of the container. As long as the lower end (18) of the plate (10) is above the liquid level, the Lamb waves are reflected at the lower boundary in order to give a feedback signal of full amplitude. If, however, the liquid level rises into contact with the plate, a mode change takes place at the surface between the plate and the liquid, which leads to a feedback signal of reduced amplitude. The arrangement can be used as a limit switch or can be calibrated, so that the liquid level can be related to the strength of the feedback signal. In a further-developed arrangement, the plate (10) is terraced, in order to offer a row of shoulders (20A, 20B) of different heights. Each shoulder leads to a corresponding feedback signal, and the analysis of the feedback signals permits the determination of the liquid level. The plate can have a length of ten metres and more and can be used as a level sensor in the primary container of a nuclear reactor. The converter and the associated electronics can therefore be arranged remotely from the liquid level (e.g. outside the reactor container). <IMAGE>

Title: Substructure for the fastening of panels on a floor, wall or similar surface of a structure
IPC: E04B9/06
Filed: 1988-08-12
Abstract: The invention relates to a substructure for the fastening of elongate panels, profiled in an essentially U-shaped manner in cross-section, on a floor, wall or similar surface of a structure, having load-bearing rails which run at a distance from one another transversely with respect to the panels, whose upper load-bearing-rail part, for fastening purposes, is adapted in shape to the shape of a respective heating appliance and whose lower load-bearing-rail part is widened to form flanges which are parallel to the surface of the structure and are intended for the abutment of longitudinal borders integrally formed at the ends of the U-legs of the panels. In order to simplify the mounting and demounting and to improve the heat transmission (the heat radiation), the invention proposes that on the flanges of the load-bearing rails there be provided lugs which form, with legs which are essentially parallel to the flanges or are directed obliquely downwards, slots with mutually facing openings, and that the panel longitudinal borders pushed into the slots be clamped fixedly, over a large surface area, between the legs of the lugs and the flanges.

Patent DE-3904926-A1 (DE)
Inventor: BERGMAN ROLF SVERRE
IPC: B60Q1/04
Filed: 1989-02-17
Abstract: A discharge lamp (16) contains a fill of xenon, mercury and metal halide. Specifically, the fill may comprise xenon at 2-15 atmospheres at room temperature, 2-15mg of mercury and 2-12mg of a metal halide mix selected from the iodides of Na, Sc, Tl, In, Sn, Dy, Ho, Tm, Th, Cd and Cs. The lamp may serve as a light source for lighting applications and is particularly suitable for automotive forward lighting applications. The xenon ingredient operates to provide for instant light necessary for automotive applications, whereas, the mercury and metal halide ingredients operate to provide for a long life, high efficiency lamp relative to either a xenon or tungsten lamp. Thus the lamp may be operated initially for the xenon only output at 5 amps and 12 volts for about 10 seconds, the current then being gradually reduced to 1.4 amps and the voltage increased to 30 volts as the other filling ingredients contribute to the light output. The dimensions of the xenon-metal halide lamp (16) may be three-fifths (3/5) of those of a typical tungsten lamp utilized for automotive forward lighting applications. <IMAGE>

Title: Device for measuring ultrasonic amplitudes
Inventor: JUNG RAINER DIPL ING
IPC: G01H11/02
Filed: 1989-03-30
Abstract: The invention relates to a device for measuring ultrasonic amplitudes which are generated by an electromechanical resonance transducer which operates in the longitudinal vibration mode, and which are transmitted via a working tool into the effective medium or to the effective location. Typical fields of application are wherever an exact indication and evaluation of ultrasonic amplitudes is required, for example in ultrasonic disintegration in biotechnology and in industrial ultrasonic processes (for example plastic welding). The object consists in developing a device for measuring ultrasonic amplitudes which enables an accurate, contactless measurement and monitoring of the ultrasonic amplitude which is non-reactive and safe against overload, especially in the case of different loadings of the working tool and in the case of aging of the active part of the ultrasonic transducer. According to the invention, the object is achieved in that the longitudinal oscillations of the transudcer effect a periodic alteration of the resonant loop frequency of a RF-oscillator by means of a ring-shaped coil (coupling loop). The electrical alternating voltage produced is related to the actual ultrasonic amplitude occurring at the tip of the working tool.
