Title: Suction device for a piston forming apparatus
Inventor: HATTORI ISAO
IPC: B30B15/00
Filed: 1986-10-08
Abstract: A suction device for a piston forming apparatus is described. The piston forming apparatus comprises a material cylinder for accommodating a blank to be extruded, a piston head arranged in a a sliding manner in the material cylinder, a hydraulic piston with a piston connected to the piston head, and a suction cap which is provided airtight in a sliding manner on the piston and has suction tubes. The piston head has a relief valve which is closed when the piston of the hydraulic cylinder advances into the material cylinder and is opened when the piston withdraws in a direction opposed to the feed direction. After the extrusion operation is complete, the suction valve is opened in order to bring the space between the piston head and a blank into a state close to atmospheric pressure. The piston head can therefore be pulled in a simple manner out of the material cylinder without a large pulling force being necessary for this purpose. Furthermore, parts of the ceramic blank which remain in the material cylinder after completion of the extrusion operation do not impair the next extrusion operation.

Title: Counter top with light-screen profiles arranged on arms
Inventor: STENEMANN BRUNO
IPC: A47F3/00
Filed: 1986-11-15
Abstract: In the case of a counter top, the front is covered by a panel and there are provided horizontal arms for holding this panel, on which arms at the same time a horizontal payment slab is supported. The arms serve at the same time to attach a light-screen profile, and at the longitudinal edge of the payment slab there is a profile rail which acts as edge stop and connects adjacent arms to one another. To develop a space-saving, simple counter top, it is proposed to use the continuous profile rail as an integral part of the light-screen profile, since in this case the one C-leg is already produced, it then merely being necessary to arrange in the space between adjacent arms a profile section comprising a C-half-profile from the other C-leg and the C-curve region.

Title: Device for protection against pollen
Inventor: SCHROEDER MICHAEL
IPC: A61F9/02
Filed: 1987-03-13
Abstract: The invention relates to a device for protection against pollen, constructed as goggles, in which, in a further development of the subject-matter according to the main patent, the filter material used is a filter matrix preferably based on synthetic fibres having a retention cut-off point of 2  mu m in gas filtration. The preferred filter material proposed is polypropylene endless filament. The goggles equipped with such a filter are able to protect their wearer from air contamination of any type. They provide effective protection against pathogenic bacteria and thus against droplet infections, as equally against other dirt particles of comparable small diameter hazardous to health, for example asbestos dusts, which can arise at certain work places. In addition, the filter material according to the invention can be stretched on cassette-like frames which can be inserted as exchangeable parts into appropriately designed holders of the wall sections of the goggles. As a result, with the same pair of goggles, filters of different materials or various mesh widths can be used.
Patent DE-3710158-A1 (DE)
Title: Ski brake
Inventor: HIMMETSBERGER ALOIS ING
IPC: A63C7/10
Filed: 1987-03-27
Abstract: In ski brakes, in which the pedal consists of two parts which can be offset relative to one another, in order to draw the brake mandrel of a brake leg, which is movably mounted in the pedal in the readiness position above the ski surface, inwards to a position above the lateral edge of the ski, and to move it out beyond the lateral edge of the ski during the movement into the braking position, a spring is present between the pedal parts which offsets the pedal parts relative to each other, and is overcome in the course of the placing of a boot towards the end of the pivot movement of the ski brake into the readiness position. In order that the brake mandrel is not drawn in prematurely during placement of the boot in the braking position, but is drawn in only after the brake leg lies above the ski surface, this spring must be of a relatively powerful design, since it acts against the erector spring. A spring of this strength, however, may have an adverse effect on the release performance of the ski binding in which the ski boot is secured. In order to manage with a relatively weak spring between the pedal parts, a locking part (11a) is provided which, in the braking position of the ski brake (1), blocks the offset pedal part (8) and releases the offset pedal part (8) during the movement of the pedal in the pivoting direction towards the readiness position of the ski brake. The ski brake, because of the spring which, in the readiness position, is imperceptible as regards the release performance of the ski binding, is suitable ... Original abstract incomplete. <IMAGE>

Title: Brake booster, particularly for a hydraulic vehicle brake system
Inventor: HAYN HOLGER VON
IPC: B60T13/50
Filed: 1987-06-09
Abstract: The brake booster (32) for the actuation of a master brake cylinder (37) has a housing (33) which is divided by a booster piston (34) into a booster chamber (38) and a vacuum chamber (39). The movement of the booster piston (34) is transmitted via a push rod (35) to a piston (36) of the master brake cylinder (37). In the vacuum chamber (39) there is a compression spring (43) which is supported on the housing (33) and on the booster piston (34). The vacuum chamber is connected to a vacuum line of a source and pressure medium. The booster chamber (38) can be connected to the atmosphere or to the vacuum line (41) by a control valve (40) actuable via a push rod (42). In the brake release position, the pressure difference across the booster piston (34) keeps the compression spring (43) under compression. For brake actuation, the pressure in the booster chamber (38) is lowered and thereby releases the stored spring force, by which the piston (36) of the master brake cylinder (37) is actuated. As a result, the boost action of the brake booster is maintained even if the supply of pressure medium fails. <IMAGE>

IPC: G01N21/03
Filed: 1987-07-14
Abstract: To provide an improved detection method with a chemical sensor which is also novel, the latter is provided with a waveguiding film comprising a selective matrix on a substrate. For this purpose, it may be constructed with or without a diffraction grating. A beam, in particular a laser beam can be guided by the selective matrix with or without diffraction grating and with or without selective additional layer and fed to a detector. As a result of the reaction(s) or subsequent reaction(s) of the substance to be measured with the selective reactant(s) in the selective matrix as such without labelling substance, a change in the physical properties takes place as a result of molecular attachment(s) or of molecular rearrangement(s) and/or molecular reactions in the form of chemical reactions. After the onset of an interaction between selective matrix and the medium containing the substance, changes in the physical properties are measured.

Patent DE-3738554-A1 (DE)
Inventor: LIESK INGRID
IPC: A61L9/04
Filed: 1987-11-13
Abstract: The invention concerns the device which automatically releases a detergent, disinfectant, deodorant or other solution into a toilet bowl after each flashing. Flashing water collects in a collector (7) whose weight forces it and the product container below it downward with respect to the suspension device. When flashing is complete, the collector empties slowly, thereby becoming lighter, and is finally pressed upward by a spring (11). Simultaneously, a rod (1) rigidly connected to the suspension device is pushed out of the lower part of the product (6). The product, which is accumulated in a cavity (5) of said rod, then falls drop by drop into a toilet bowl or is flashed out by the remaining water emptying from the collector (7).

Title: Compression turbine engine
Inventor: WILHELM JOSEF
IPC: F02B3/06
Filed: 1987-12-31
Abstract: A turbine engine which consists of three funnel-shaped housings. The outer is the fixed shell (block) onto which the inwardly directed cylinder is screwed from above. The middle one is the rotary (drive) housing, in which the fresh air fan is located at the bottom. The compressed air fan is arranged in the middle, and the drive blades are arranged at the top. The cylinder seat and all the ducts for the fresh air and compressed air fan are in the inner housing, together with the housing and the bearings of the supporting wheels. The supporting wheels have many individual openings from the side. Compressed air is blown into these openings by the compressed air fan, and can exit via ducts and openings on the sliding slots. In this case, the compressed air presses on both the upper and lower surfaces of the drive blade. This device serves as a substitute for lubricating the sliding slots and blade surface. When this turbo-engine is driven to generate power, it is, however, also possible to use steam for this device. This turbine engine can also be used to pump air and water at high pressure. For this purpose, air or water is used as the respective mass for the device. When using types of energy such as, for example, diesel oil, kerosene, etc., the exhaust pot acts as a heat exchanger in which the air is pressed out downwards on the opposite side of the same supporting wheel from the motor half where the combustion gases press onto the drive blade, and ...
