Patent DE-3108275-A1 (DE)
Title: Diaphragm-type pressure regulator with a disturbance protection diaphragm, a built-in control pressure regulator with a limited setpoint pressure and a safety shut-off valve, for regulating the pressure of gaseous and liquid media
Inventor: HERPERTZ HEINRICH
IPC: G05D16/06
Filed: 1981-03-05
Abstract: The patent application relates to a diaphragm-type pressure regulator with a disturbance protection diaphragm, a built-in control pressure regulator with a limited setpoint pressure and a safety shut-off valve, for regulating the pressure of gaseous and liquid media. 1) The invention relates to the combination of two independently operating valves, one acting as a safety shut-off member and the other acting as a pressure regulating member, which are installed in a normal commercially available valve bottom part. This has a material-saving effect and thus saves costs. The previous expensive construction of a two-seat valve body is thus eliminated. The use of a single-seat valve bottom part with the two shut-off members was made possible by the fact that the mechanical actuation of the safety shut-off member is performed by the diaphragm-type pressure regulator in the course of its operation. 2) The production of a large-diameter diaphragm housing to hold a large working diaphragm is eliminated because the regulated control pressure is immediately passed under the small closing diaphragm. This allows cost-saving production. 3) The installation of a small disturbance protection diaphragm which does not have a negative effect on the regulating function gives increased reliability of operation. 4) The arrangement of a second outflow nozzle in the control pressure regulator ensures that the diaphragm-type pressure regulator closes rapidly and prevents the back pressure from rising beyond the setpoint pressure. This is a significant technical advance.

Filed: 1982-01-20
Abstract: The invention is a shaped article of boron nitride having a density of at least 95% of the theoretical density which consists of polycrystalline hexagonal boron nitride in the form of a homogeneous isotropic microstructure and which has been manufactured from pure boron nitride powder without the concomitant use of sintering aids by isostatic hot-pressing in a vacuum-tight casing at temperatures of from about 1200 DEG  to 1500 DEG  C. under a pressure of from about 50 to 300 MPa. Boron nitride powders having a free boric oxide content of not more than 1.0% by weight and having a specific surface area of from 5 to 30 m2/g are used as starting material. The powders either are filled into prefabricated casings consisting of steel or glass and densified by vibration or are preshaped to form green bodies having pores open to the surface and then placed in prefabricated casings or coated with a material which forms a vacuum-tight casing. The powders or the preshaped green bodies in the vacuum-tight casings are then subjected to an isostatic hot-pressing process in a high-pressure zone using an inert gas such as argon or nitrogen, as the pressure-transfer medium.

Title: Process for thickening a pulp mixture or a sludge and a disc filter for application of the process
Inventor: TUOMI ALPO
IPC: D21D5/02
Filed: 1982-03-19
Abstract: A process and a device are described for thickening a pulp mixture or a sludge by means of a rotating disc filter partly submerged in a pulp mixture or sludge situated in a tank. For this purpose, a superatmospheric pressure is present outside the filter area of the discs. Air at superatmospheric pressure is used not only for the filtration but also for detaching the filtered pulp from the filter surface of the discs, that is by supplying air at superatmospheric pressure to each disc within the sector where detaching is to take place. From there the air is blown out through the filter surface to the outside of the filter surface. The filter has a tank, a box located above the tank and filter discs mounted on an axle and composed of sectors, and rotating in the tank. To produce the superatmospheric pressure outside the filter surface of the discs, the longitudinally arranged hollow cavity within the axle is connected to the source of superatmospheric pressure and to each disc sector situated in the detaching position.

IPC: B23Q17/00
Filed: 1982-07-31
Abstract: The invention relates to a device for determining the working range of a double-acting clamping cylinder for actuating clamping devices on machine tools, in particular interchangeable chucks on lathes, the drives of which, for carrying out the machining of the workpiece, are locked if the clamping cylinder is located outside the respective working stroke, with a control rod which is connected to the clamping piston of the clamping cylinder and the movement of which is monitored for the monitoring of the respective working stroke while allowing for retightening strokes. In order to positively establish the working stroke of the clamping device used in each case, the positions of the control rod monitored by sensors, which positions are produced by an idle stroke (corresponding to the total stroke) of the respective clamping device and limit the respective working stroke, can be stored for the duration of an uninterrupted machining operation. These positions of the control rod, which in each case guarantee a retightening stroke, are automatically deleted if the machine tool is switched off or if the clamping device is changed.

Inventor: BRUCKHOFF HENNING
IPC: H04R29/00
Filed: 1982-10-20
Abstract: A measuring device for checking the tightness of an ear impression mold serving as pattern for the production of an otoplastic and/or of an otoplastic inserted in the auditory passage of an ear through which an air pressure deviating from the air pressure prevailing on the outside can be produced, via an air permeable connection, in the inner space defined by the ear drum and the ear impression or otoplastic. Through the device changes in the generated deviating air pressure can be measured. The air permeable connection is connected to a pump serving for the generation of the deviating air pressure via a pressure chamber whose volume is a multiple of the volume of the inner ear space. A control circuit presetting the timing of the pumping and measuring process is provided. The device is insensitive to differences in the volume of the inner ear space and produces reproducible test results which reliably indicate the quality of the ear impression of otoplastic.
