Patent DE-3705321-A1 (DE)
Title: Instrument for measuring differences in pressure
Inventor: RAMPF HERBERT
IPC: G01L9/00
Filed: 1987-02-19
Abstract: The invention relates to an instrument for measuring differences in pressure by a piezoresistively operating sensor, in which the sensor can be exchanged and in which no leakages, and resulting falsified measured values, occur at pressures from 8 to 12 bar. In the case of the instrument according to the invention, additional devices, for example a temperature sensor, can also be fitted in the instrument. These requirements are met by the piezoresistively operating sensor being arranged in a demountable metallic housing which essentially comprises an overpressure part, an underpressure part and a connecting element, the overpressure part and the underpressure part being designed such that a suitably shaped volume is produced for receiving and positioning the sensor between the two components, and the overpressure part and the underpressure part being such that they can be pressed against the sealing surfaces of the sensor with the aid of the connecting element.

Title: Seat, in particular vehicle seat
Inventor: FAUST EBERHARD DIPL ING
IPC: B60N2/90
Filed: 1987-03-12
Abstract: In the case of a seat, in particular a vehicle seat, with a backrest which has as a supporting structure a moulded shell with a centre part and two side-guiding parts in one piece therewith, for the purpose of obtaining the same seating comfort for people of extremely differing body size, the moulded shell is made of elastic material and matched approximately to the width of the back of an average to large seat user. The moulded shell is suspended in the region of its side-guiding parts resiliently on an essentially rigid backrest frame. The suspension takes place via straps which engage, on the one hand, on the rear side of the side-guiding parts and, on the other hand, on the front side of the backrest frame facing the moulded shell. Spring elements, torsion bars or a torsionally weak design of the backrest frame ensure that the straps are resiliently flexible for the purpose of an automatic, resilient adjustment of the side-guiding parts.

Title: Liquid-crystal display device and method for producing the same
Inventor: KNOLL PETER DR
IPC: G02F1/1333
Filed: 1987-04-04
Abstract: A liquid-crystal display device of the twisted nematic type is described, in which the carrier substrates consist of plastic. In order to simplify the production of such display devices and to prevent the consequences which follow from the frequently occurring birefringence of the plastics, in accordance with the invention the polarisers required for large TN-LCD are integrated into the display device, specifically preferably in such a way that the carrier substrate directly contains a polarising material such as iodine which was uniformly aligned in the substrate material by stretching the latter. <IMAGE>

Title: Spray insert for elastically deformable liquid vessels
Inventor: HEINLEIN HANS
IPC: B05B11/04
Filed: 1987-04-16
Abstract: A spray insert with an essentially hollow cylindrical head part insertable in the vessel neck with a liquid suction tube which extends close to the vessel base and with a nozzle insert which has a central nozzle orifice and is insertable into that end of the head part remote from the vessel is already known. The invention aims to provide an improved spray insert of this kind, in which an excellent mixing of air and liquid takes place to form a very fine spray mist which emerges from the nozzle orifice irrespective of whether the liquid vessel is held in a perpendicular or laterally obliquely inclined position and is deformed for the spray-mist discharge. In the case of the novel spray insert (1), the nozzle insert (10) has a spray head with one or more air orifices (25, 26) and a liquid suction nozzle (11). In particular, a spray chamber or vortex chamber (29) connected to the nozzle orifice (17) is formed in the spray head in such a manner that a fine spray mist can be sprayed out with the liquid vessel in any position. Spray insert for liquid vessels, for example for the application of liquid medicaments, in particular for treating colds (nose spray device). <IMAGE>

In order to use fossil fuels with low intake and to avoid the environmental pollution caused by the combustion of these fuels, the method according to the invention is characterised by the following steps:   - atomising liquid supplied to the container, by ultrasound action,   - infrared radiation action on the container and thus heating of the atomised liquid situated in the container, - conducting off of the pressurised steam thus formed to the turbine, and - return of the liquid recovered by condensation into the container.
Patent DE-3733533-A1 (DE)
Title: Driving device for rotatably mounted tools
IPC: B23C5/00
Filed: 1987-10-03
Abstract: The driving device shown is formed by a driver (1) and the special design of a cutting tool (2) which from a tool shank (10) merges via a slim truncated cone (11) into the cutting part (3). Sitting on the bottom end of the tool shank (10) is the sleeve-like driver (1), which widens from the diameter of the tool shank (10) towards the top in a trumpet-like end face (13) in which spiral sliding grooves (14) are formed, the width (b) of which increases towards the top or towards the tool shank (10). Two transversely running coupling lugs are designated by (17). The coupling lugs (17) can engage in a transverse groove of, for instance, a drive spindle; in other words they are part of a power-transmission path of the drive spindle via the driver (1) on the tool shank (10). This coupling connection engages with greater torque free from shock and thereby protects tool and workpiece while deforming the driver (1), which is made of an elastic material and can also perform the function of a predetermined breaking point. In this arrangement, the guide grooves (14) serve the purpose of throwing off in particular long fibrous chips radially to the outside in such a way that the chip material can be easily caught and fed to a transport device for further transport. <IMAGE>

Title: Method of operating a semiconductor gas sensor working on the calorimeter principle and having a plurality of sensor elements
Inventor: MUELLER RUDOLF PROF DR
IPC: G01N27/16
Filed: 1987-10-26
Abstract: A gas sensor working on the calorimeter principle comprises sensor elements on whose surface, coated with a catalyst (2), the gas to be detected reacts catalytically with evolution of heat. By means of supply of heating power modulated over time (P(t)), the sensor elements maintain a modulated base temperature. Since the catalytic reaction of gases is strongly dependent on the catalyst temperature, the resulting signal likewise shows a modulation which arises, besides from the temperature modulation, also from the heating as a result of the catalytic reaction. Measurement parameters are therefore amplitude (A2) and phase ( phi 2) of the base wave proportion and of at least one harmonic wave proportion, e.g. the proportion of the second harmonic wave, of the resulting signal. <IMAGE>

Patent DE-3811317-A1 (DE)
Inventor: CALLSEN HANS
IPC: A22C21/00
Filed: 1988-04-02
Abstract: An important characteristic in obtaining meat from poultry carcasses is, in preparation for this, the handling of the carcass in the area of the clavicle (4), where the problem to be solved is to ensure that, even in cases where the clavicle is broken, that breast pieces of this do not remain in the breast meat. This problem is solved by inserting a shaped block (18) into the V-shaped section of the clavicle, said shaped block having in plan view a wedge shape, the flanks of which are provided with slot-like grooves (26), into which the branches of the clavicle can fit, so that these disappear into the grooves. The clavicle can then be scraped clean on its outside surface, by means of scraper knives (32) guided over the flanks of the shaped block, without the danger that any broken pieces will be picked up and lifted out.
