Title: Grinding or polishing wheel
Inventor: REILING REINHOLD
IPC: B24B27/027
Filed: 1982-06-18
Abstract: The invention relates to a grinding or polishing wheel as an extension of German Offenlegungsschrift 3038850, where the object of the invention is to obtain a simple and faultless handling with respect both to a limited flexibility as well as for a reinforcement of the spindle for surface grinding and polishing on the one hand, as well as for edge grinding and polishing on the other hand, and to ensure protection against overload of the flexible spindle. To this end, threaded couplings are placed on the flexible spindle at a certain distance from one another for purposes of lateral flexibility, the one threaded coupling holding by means of a flange and spigot nut the intermediate disc and the second threaded coupling being used to take up the spigot nuts which can be screwed with the two threaded couplings for purposes of reinforcement. <IMAGE>

Title: Narrow-gauge film cassette with a film pressure plate
Inventor: POETTER BERNHARD
IPC: G03B17/26
Filed: 1982-07-03
Abstract: The exposure opening (2) of the cassette housing (1) of a narrow-gauge film cassette is sealed by a film pressure plate (5) which is pressed resiliently against the rear of the film on the inside of the cassette. The film pressure plate (5) has a recess (9) in which an image pressure plate (10) is arranged. The image pressure plate (10) is connected to the film pressure plate (5) by a spring (11). When the film pressure plate (5) is raised from the rear of the film during insertion of the cassette into a film camera, the image pressure plate (10) remains resiliently seated on the rear of the film and presses the film (3) against the film gate (4) of the camera. As a result, changes in the distance of the film (3) from the film gate (4) and changes caused thereby in the image sharpness are prevented. <IMAGE>

Inventor: HUNOLD KLAUS DIPL ING DR
IPC: G01K7/06
Filed: 1982-09-28
Abstract: The invention is an improved theroelement which comprises a graphite/boron carbide thermocouple, the arms of which are constructed as a tube and a rod, arranged concentrically inside the tube, which are electrically connected at one end. One of the arms of the thermocouple consists essentially of boron carbide formed from self bonding boron carbide by pressureless sintering. Prefabricated sleeves of high-purity, boron-oxide-free hexagonal boron nitride are used between the arms of the thermocouple as spacers. Only the end of the arm of the thermocouple constructed as a rod is secured in an electrically conductive connecting piece and the arm is freely mobile in the direction towards the cold junction. As the material for the arm of the thermocouple constructed as a rod, there can be used, for example, boron carbide having a coarse-grained structure and a density of from 60 to 80% TD, which has been manufactured from boron carbide powder having bimodal particle size distribution by means of extrusion, followed by pressureless sintering at from 2000 DEG  to 2250 DEG  C. The thermoelement can also be manufactured in one operation by means of pressureless sintering of the boron carbide powder in situ. Such a thermoelement comprises, for example, a flexible graphite cord for the arm of the thermocouple constructed as a rod, a boron-nitride envelope and a boron-carbide casing, the envelope and casing having been formed from powders sintered in situ without pressure.

Title: Self-adhesive tape with adhesion coating on both sides and process for manufacturing a self-adhesive tape
Inventor: SIEBER-GADIENT PAUL
IPC: C09J7/20
Filed: 1982-11-25
Abstract: The self-adhesive tape (1) has an underside (10) with an adhesive layer (3) covering the backing fabric (2) only superficially. On its top side (11) it has an adhesive layer (4) flatly covering the backing fabric (2), which adhesive layer is directly adjacent to a release paper (5). The backing fabric (2) produces unevennesses only on the bottom side (10) through the crossing points (23) of warp (20) and weft (21), which fact results in the lower adhesion-capacity of the lower adhesive layer (3), compared with the adhesion-capacity of the upper adhesion layer (4) flatly adjacent to the release paper (5). The adhesive layers (3, 4) are collated together in the fabric openings (22), permitting the indivisibility of the complete self-adhesive tape (1). The self-adhesive tape (1) can thus be used removably, its bottom side (10) being allocated to a floor and its top side (11) to, for example, a carpet. <IMAGE>

Title: Roller shutter run-in funnel
Inventor: BRUENEMANN HELMUT
IPC: E06B9/58
Filed: 1983-12-03
Abstract: Placed as endpiece on the upper end of a lateral guide rail (5) of a roller shutter is a roller shutter run-in funnel (6). Mounted rotatably on a shaft (9) in the rear funnel part (7) is a guide roller (8) which projects beyond the rear funnel part (7) both upwards and towards a roller shutter armour (2). It is thus achieved that the individual slats (4) of the roller shutter armour (2) are subjected only to extremely low mechanical stresses both during opening and during closing of the roller shutter, as unrolling can take place in the region of the guide roller (8) in contrast to a sliding stress in such run-in funnels as have no guide roller. The noise produced is considerably reduced by this measure, as is the mechanical wear of the slats (4) as a result of friction. <IMAGE>
Patent DE-3345605-A1 (DE)
Title: Novel toothbrush
Inventor: BARTH MATHIAS OTTO
IPC: A46B7/04
Filed: 1983-12-16
Abstract: In this novel toothbrush the handle piece is for the first time made of an integral, dimensionally rigid, relatively thin, skeleton-like metallic frame of a corrosion-resistant steel wire preferably having a chromium-plated, polished surface, instead of its customary, flat plastic handle with its bundle of bristles starting at its top end, in the slightly resilient top part of which whose inner dimensions resemble the outer shape and the dimensions of a normal, but separately made bristle body, such a small plastic bristle body can be inserted with a press fit into a receiving orifice formed by corresponding, dimensionally correct bending of the steel wire. This separate plastic bristle body can be exchanged, if and when required, with another new bristle body any number of times and without any problems by pressure with the fingers. Every insertion and exchange of the bristle body in its frame-like metal handle are facilitated by its very cut-off edges at the bottom side, whereas locking thereof is caused by a peripheral, semicircular recess corresponding to the radius of the rounding of the metallic frame profile approximately in the middle of the narrow sides of the bristle body. Release and removal of a used, unsightly bristle body from its frame are carried out by appropriate finger pressure on its rear surface.

Title: Device for the individual separation of seeds
Inventor: WEINHAUER DIETER ING GRAD
IPC: A01C7/04
Filed: 1984-01-04
Abstract: The invention relates to a device for the individual separation of seeds. Mounted rotatably in a housing is a cellular wheel which has funnel-shaped bores for receiving the seeds. The cellular wheel is guided through below an airstream, which removes the excess seeds from the funnel. Arranged on the circumference of the cellular wheel is a ring which terminates flushly with the cellular wheel and which projects approximately half-way into the funnels. In the region of the funnels, this ring is provided with bores which are smaller than the smallest grain. Because air is blown in, a dynamic pressure is built up in the funnel and suction is generated in the bore. In each case one grain will thereby come in front of the bore and be retained there.
