Patent DE-3737204-A1 (DE)
Title: Device for the dosed transfer of liquids
Inventor: AMELUNG ROLF DIPL ING
IPC: G01F11/28
Filed: 1987-11-03
Abstract: A device for the dosed transfer of liquids, preferably body fluids such as blood plasma and the like, with which a predetermined quantity of liquid (12) may be extracted by means of a suction pump (1) via a pipette (10) from a primary vessel (5) and conveyed to a test cell, and in which the liquid level for determining the immersion depth may be ascertained by a measuring device, is configured according to the invention in such a way that the measuring device comprises an acoustic signal transmitter (2), a signal receiver (3) spatially separated therefrom, a resonator (6, 7, 9) arranged between the signal transmitter (2) and the signal receiver (3) and an amplifier (8). In this case, the signal transmitter (2) is connected to the output of the amplifier (8) and the signal receiver (3) in connected to input thereof. With the aid of the amplifier (8), feedback is achieved which depends on the chamber volume of the resonator (6, 7, 9) and which determines its natural frequency. With closure of the pipette opening, such as occurs, for example, when the pipette meets the surface of the liquid (12), the resonant frequency changes so that the liquid level is thereby satisfactorily ascertained. In contrast to the known systems, which undertook measurement in electrical ways, the liquid to be extracted, especially blood plasma to be extracted, is in no way influenced by the device according to the invention. <IMAGE>

Patent DE-3738176-A1 (DE)
Title: Optical switch
Inventor: VOLKMAR RALF REINER
IPC: G02B6/35
Filed: 1987-11-10
Abstract: For the purpose of forming stop surfaces in the switching positions of the switch, a threaded bolt which is aligned with its axis perpendicular to the path of travel of a switching piece projects with its conically-shaped free end into the region of pins which are connected to the switching piece and alternately come to stop on the conically-shaped free end of the threaded bolt in the switching positions of the switch. When the threaded bolt is adjusted in the axial direction by means of a fine-pitch thread, the conical end is then as a result displaced relative to the pins, as a result of which the stop between the pin and the conical end of the bolt can be adjusted very precisely in the direction of travel of the switching piece as a function of the bevel of the conical end. <IMAGE>

Patent DE-3800680-A1 (DE)
Title: Process and appliance for coating a substrate
Inventor: JUERGENS ANDREAS
IPC: C23C14/28
Filed: 1988-01-13
Abstract: The invention relates to a process and an appliance for coating a substrate, employing a laser beam which is directed at a target. The substrate and the target are situated within a vacuum chamber. In order to inject the laser beam into the vacuum chamber, a gas cloud is proposed for the purpose of protecting the optical window, which cloud is delimited, in particular, by a chamber provided with a nozzle. The gas cloud prevents any deposits on the inside of the optical injection window and thus prevents destruction of the window by overheating.

Title: Process and apparatus for energy saving during beer wort boiling
Inventor: WOLFSEDER ALFONS
IPC: C12C13/02
Filed: 1988-06-07
Abstract: For further saving of primary energy in an external barometric boiling, as disclosed in DE-A 3608416, thermal vapour compression is used. A steam-jet compressor (10) is advantageously used which sucks in a part-stream of the vapours released from the evaporation vessel (3), mixes the part-stream with the steam at a higher pressure and compresses the mixture to the boiling pressure of the external boiler (2). By means of the excess vapours, there proceeds at the same time in the vapour condenser (13) either, in a semicontinuous boiling process, a direct lautered wort preheating from about 72@C to about 96@C or, in a discontinuous process, initially a water preheating from about 78@C to about 96@C, in order then, by means of this hot water to be temporarily stored, to preheat the lautered wort of the next brew via a plate heat exchanger, not depicted, from about 72@C to about 93@C. By means of this additional thermal vapour compression in combination with the lautered wort preheating, primary energy savings of 60-65% are achieved which are comparable with mechanical vapour compression, but are achieved with considerably lower capital and maintenance costs. In addition, a reduction of the environmental pollution of up to 96% can be achieved. The vapour and external boiler condensate arising is collected in the condensate vessel (14) and cooled in the downstream condensate cooler (15) to about 25@C (air pollution control ). In the course of this, in the ... Original abstract incomplete. <IMAGE>

Title: Cassette loading device for video cassette recorders
Inventor: HWANG HAK SUN
IPC: G11B15/18
Filed: 1988-09-15
Abstract: The invention relates to a cassette loading device for video cassette recorders, which uses the drive force of a tape drive motor by means of a drive force switch-over unit. The latter comprises a drive (gear) wheel, which meshes with a worm of a cassette loading unit, a rocker arm, which is provided with a bent-off section (at one end) and lifting elements (at the other end), a driven belt pulley, which is provided with teeth or claws and to which the drive force of the tape drive motor is transferred, a rotating element, which is provided with teeth or claws which are opposite those of the driven belt pulley, and a pressing (helical) spring, which is inserted between drive wheel and rotating element. The drive force switch-over unit effects the transfer of the drive force of the tape drive motor to the cassette loading unit under the spring force of the pressing spring and the discontinuation of the drive force transfer by means of the lifting movement of the rocker arm, the bent-off section of which is pressed downwards by a function plate.

Patent DE-3839655-A1 (DE)
Title: Push-button with a pressure sensor
Inventor: GRAFENHORST HEINRICH DIPL ING
IPC: G04G21/08
Filed: 1988-11-24
Abstract: The setting process of many electronic devices is a lengthy process, because of the (digital) display which clocks at a constant speed. In the case of rapidly clocking displays, a precise setting of a value during the setting process would hardly be possible, owing to the poor reaction time of humans. By means of a pressure sensor integrated into the setting pushbutton, the clock speed of the display can be varied as a function of the pressing force, by which means a higher operating comfort is achieved in many electronic devices.

Filed: 1989-03-08
Abstract: To simplify the manufacture and assembly of a scale platform, it is proposed to insert the force measuring cells laterally from the outside through lateral installation openings, in particular the open end faces of longitudinal and transverse carriers of the platform frame. Apart from the reduction of the components, a shortened assembly time results and, by means of the use of large-area supporting elements, the possibility of dispensing with a foundation. Furthermore, it is proposed to build up the weighing platform from transverse carriers and longitudinal parts which can be assembled in modular fashion, so that a scale platform which can be extended in length arbitrarily is produced at low manufacturing costs.

Title: Device for shutting off pipelines, ducts or other cavities
Inventor: MOEWS HARALD DIPL ING
IPC: F16L55/124
Filed: 1989-04-27
Abstract: The invention relates to a device for shutting off pipelines, ducts or other cavities in the low-pressure and medium-pressure range, in particular gas pipelines. The object of the invention is to provide a device which makes it possible to shut off cavities with deposits and tolerance deviations permanently, securely and within a short period of time, with simple handling. According to the invention, this is achieved in that the shut-off device which is to be introduced through a bore into the pipeline or the duct comprises a gas-impermeable fabric, the surface area of which is greater than the internal pipe or duct cross-section, which is enclosed in a gas-tight manner on its outer periphery by a hollow profile acted upon by fluid, and which interacts with a carrier which passes centrally through the fabric. The carrier, functioning as introduction and stabilisation device, fixes the sealing device at three points. In addition to the through-passage location on the fabric there are, diametrically opposite one another, two connections to the elastic hollow profile, of which at least that connecting location which is directed towards the bore in the operating state is designed in a flexurally rigid manner. <IMAGE>
