Patent DE-3216000-A1 (DE)
Title: Semicircular seal
Inventor: UKAI MIKIO
IPC: F02F11/00
Filed: 1982-04-29
Abstract: A semicircular seal contains a metallic part (1) and a flexible part (2) for sealing off the hole in the cylinder head during adjustment. At least one portion on the metallic part comes into partial contact with the surface of the hole. The semicircular seal adapts easily to the configuration of the hole and it is not necessary to use a sealing fluid. The tightening torque of the cylinder head can be kept low and the sealing effect is not lost even over several years since virtually no ageing influences are operative. <IMAGE>

Title: Diamond cutting-off disc, in particular for working natural or synthetic stone
Inventor: BIEDRON RALF
IPC: B23Q11/00
Filed: 1982-06-01
Abstract: Such a diamond cutting-off disc consists of a circular metal disc (1) on which diamond bodies (5) in segment form are fastened to the periphery at a distance from one another, preferably by brazing, and in which there is a radial notch (4) between the end and the start of the next respective diamond body (5), which notch (4) starts from the periphery and its radial length is greater than the radial thickness of the diamond bodies (5). To prevent the troublesome noises in the form of high-pitched whistling sounds occurring in particular during idling, a recess (6 or 6a) partly or completely overlapping the notch laterally and in the longitudinal direction is contained in the wall of the metal disc (1) in the area of each notch (4), in which recess (6 or 6a) a plate (7) is embedded and fastened in a positive-locking manner and so as to be flush with the surface. The recesses (6, 6a) are preferably arranged alternately on the one and the other side of the metal disc (1) and are of circular design. <IMAGE>

Title: Rod-shaped device for fastening an artificial dental crown
Inventor: HAHN RICHARD DR DR
IPC: A61C13/30
Filed: 1982-06-29
Abstract: The invention relates to a rod-shaped device for fastening an artificial dental crown in a dental root having a head (6) and a pin (5), the head (6) projecting laterally with its underside (4) beyond the pin (5). The conical pin (5) of the rod (1a) has a roughened zone (9) formed by cuts (10) which extends over the entire circumference of at least one part of the surface of the pin (5). The underside (4) of the head (6) also has sharp-edged cutting rough zones (13). The quarter of the pin (5) close to the head has a smooth zone in order to permit bending of the head relative to the pin. The end (11) of the pin (5) comprises a smooth final zone (12). The invention resides in the facts that 1) a pin which acts like a drill due to its rough zones is worked directly into the root canal and can at once remain in the tooth, 2) bending and adaptation of the pin head relative to the pin are immediately possible, so that adaptation to the neighbouring teeth and the teeth in the opposite jaw is easily possible, and 3) maximum bracing and high strength in the connection of the pin structure to the tooth stump are achieved in the simplest way by pressing the rough underside of the head against the flat cut surface of the root stump. <IMAGE>
Patent DE-3229258-A1 (DE)
Title: Holding arm for a bearing frame for a stretcher or the like
IPC: A61G1/06
Filed: 1982-08-05
Abstract: A holding arm (1) for a bearing frame for a stretcher (7) comprises a carrying beam (2), on one end of which a withdrawable part (3) is inserted so as to be adjustable in length. An axial stepped slot (10) is formed, in the wall of the withdrawable part (3), through which a bolt (9) firmly connected to the carrying beam (2) projects, onto which bolt a tensionable threaded body (11) is screwed. The stepped slot (10), conjointly with the bolt (9), guides the withdrawable part (3) in such a way that the latter can be rotated about approximately 90 DEG  after a short linear withdrawal movement, so that locking of the withdrawable part (3) in the withdrawn position is achieved by engagement of the bolt (9) in one edge of the slot. At the same time, rotation of the withdrawable part results in pivoting of the stop (5), which is connected to the withdrawable part (3), out of the path of the stretcher (7) to be placed on the holding arm (1) or to be removed therefrom. <IMAGE>
Patent DE-3229992-A1 (DE)
Inventor: FEICHTINGER KURT
IPC: G01B3/22
Filed: 1982-08-12
Abstract: A multicoordinate sensing head is disclosed which incorporates a particularly simple mechanical structure to mount the sensing pin in a casing such that the pin is movable in a plurality of directions. Each deflection of the free end of the sensing pin is converted by appropriately shaped components on the sensing pin and the casing into an axial movement of a radially constrained upper end of the sensing pin. The slight axial movements of the upper end of the sensing pin brought about by deflections of the free end of the sensing pin are registered by a photoelectric arrangement arranged in the region of the upper end of the sensing pin. This photoelectric arrangement generates a signal when the free end of the sensing pin is deflected.

Title: Composting device
Inventor: FREI WALTER
IPC: C05F17/02
Filed: 1982-09-03
Abstract: A composting device has approximately vertical posts or similar supporting structures and lateral components which connect these posts or support structures transversely and are arranged one above the other, generally leaving a space between each other, the posts being provided, at their lateral surfaces which receive the lateral components, with tabs which are arranged one above the other at a distance and protrude upwards in an oblique fashion while the end regions of the lateral components are provided with perforations which fit around these tabs. This allows the lateral components to be hung from these tabs in a simple manner. For sufficient stability, the lateral components are provided with two perforations on each end, the distance of which corresponds to the distance of two tabs or, preferably, to an integral multiple thereof, for example twice the distance. This allows the lateral components to be displaced vertically by approximately half their width so that the distances between the lateral components can be varied easily.

Title: Feed device for a punching and bending machine
Inventor: MAUDERER ERNST DR
IPC: B21F1/00
Filed: 1982-09-22
Abstract: The feed device has a slide 20, which is guided in a manner which allows its displacement backwards and forwards along a fixed rod 16 and a rotatable shaft 18. A movable clamping jaw 34 for the strip 50 of material is arranged on the slide 20. The clamping force is provided by a spring 38. The clamping jaw 34 is controlled via the shaft 18, which at one end of the stroke is rotated through a small angle in one direction and at the other end of the stroke is rotated back through the same angle. Guided in longitudinally displaceable fashion on the shaft 18 is a cam disc 52 which, for its part, is rotatably mounted in the slide 20. Two ball sleeves 58 of the cam disc 52 engage in longitudinal grooves of the shaft 18 and transmit the torque. The shaft 18 simultaneously serves for the longitudinal guidance of the slide 20 and for actuating the movable clamping jaw 34. <IMAGE>

Title: Liquid-crystal cell with plastic backing plates
Inventor: KRUEGER HANS DIPL PHYS
IPC: G02F1/1339
Filed: 1982-09-23
Abstract: The construction of the proposed plastic display is as follows: proceeding from the inside surfaces of each of the two backing films (1, 2) there are layers (6, 8) which are in contact over a large area. Inside the cell chamber, each layer covers the electrode-free regions of the film supporting them. One of the two layers (mask layer 6) (which is dark in colour) also overlaps the electrodes (4) of the associated film (1) in such a way that the position and shape of the switchable liquid-crystal regions are thereby defined. In a preferred embodiment, the mask layer (6) is supported by the front film (1) and is roughly aligned with the other layer (support layer 8). It is advisable to manufacture both layers (6, 8) and the frame (3) from the same material, expediently a curable synthetic resin adhesive capable of being screen printed and to colour the mask layer (6) with graphite. A cell of this type has several advantages: the effort expanded on aligning and spacing is small, the liquid-crystal substance remains protected from atmospheric moisture, the dark image background is produced without additional measures and the mask can be conductive. <IMAGE>

Abstract: Illuminating device with at least one combustion point for a flame which is fed with liquid fuel, and a container for receiving the fuel, and also a transport device, usually designated as a wick, to transport the fuel from the container to the flame. However, such a conventional wick is consumed during combustion and moreover becomes sooty as a result. This kind of soot and the consumption of the wick are to be prevented. This is effected in that the container can be ventilated and has at least one opening into which a plurality of the capillary ducts are inserted, of which inner ends dips into the fuel and the outer end of which is open outside the container and constitutes the flame site.
Patent DE-3305290-A1 (DE)
Title: Holder for a lowerable luminaire cover
Inventor: BRUEGGEMANN JUERGEN
IPC: F21V17/16
Filed: 1983-02-16
Abstract: It is sometimes impossible for reasons of design to pivot the luminaire cover (e.g. louvre) directly out of the housing. In these cases, the cover is firstly drawn vertically downwards, it then being held by springs on the housing. The subject matter of the invention is a holder such as permits the cover (3) to be drawn out and subsequently pivoted away and also completely detached, and in which a perfect chassis earth connection is ensured between the cover and housing. This purpose is served by an approximately M-shaped supporting spring (4), which is guided in the luminaire housing (1) and engages by means of angular bearing arms (411) in bearing pieces (311) in the rim of the cover (3). <IMAGE>

Title: Potter's kiln
Inventor: SCHOORL NICOLAAS
IPC: F27B11/00
Filed: 1984-02-11
Abstract: An easily transportable potter's kiln is characterised by certain constructional features. A truncated sheet metal pyramid results, which preferably has a square base, although this can also be triangular or polygonal. One side of the base is in a proportion of about 2:1 to one side of the pot surface, and an optimum kiln is provided with this construction. The shape of a pyramid also has the advantage that several kilns can be nested for storage and then take up little room. The kiln door can easily be closed by its own weight, so that no hinges or bolts for the usual closure are necessary. The slanting position of the side surface of the kiln makes such usual measures superfluous.

Title: Apparatus for the storage and metered delivery of glue and similar application masses which can age
Inventor: KREMER WALTER
IPC: B05C21/00
Filed: 1984-04-27
Abstract: An application tool (13) for glue and similar application masses which can dry out is held, easily removably, on a mounting (38) in a storage area (10) which is closed airtightly from the exterior by a flap cover (19) which can be pivoted up, and forms in the lower part a liquid reservoir (49) with an evaporation surface (50) extending over the whole floor of the area. The pressure plunger (61) of a pump (53) is actuated on each pivoting action via a flap cover (15) which closes an access opening (54) to the storage area (10). The said pump supplies spray nozzles (55) in a pulsed fashion for spraying onto the application roller (60 and 58) for spraying into the tool receiving part (40) for application mass. A delivery opening, which can be closed by a slider (27), for application mass from a raised supply container (8) is fitted above the feed opening (39) for replenishing the receiving part (40). In each working pause, it is only necessary to set the application tool (13) on its mounting (38) and to open the slider (27) briefly. In the replenishment process, the tool is thus moistened and an atmosphere of increased moisture content is produced in the storage area (10). <IMAGE>

Title: Apparatus for carrying out plasma discharges in gases
Inventor: SUPPAN FRIEDRICH DIPL CHEM
IPC: B01J12/00
Filed: 1984-07-07
Abstract: In an ozone generator, the process gas alternately flows through discharge sections (17) in which pulse-induced plasma discharges are carried out and through discharge-free cooling sections (18) in which no discharge takes place. The electrodes (12) have pulses applied to them in such a way that each quantity of gas passing through the discharge section (17) in question is subjected to a discharge process. The cooling between the individual discharge processes results in reduced decay of the ozone formed. In the cooling sections (18), detrimental ions are removed from the process gas. <IMAGE>

Title: UV-sensitive photoelement and method for the fabrication thereof
Inventor: ANGERSTEIN FLEIN DIPL PHYS DR
IPC: H01L31/103
Filed: 1984-07-17
Abstract: The invention relates to a UV-sensitive photoelement made of a pn material, the p-doped surface zone exposed to the incident light being designed in a reticulate manner, so that insular semiconductor regions connected with n-doped substrate materials fill the gaps of the reticulate surface zone. As a result, the light hitting the gaps generates charge carriers in areas having a higher carrier lifetime, and as a result the photocurrent generated by short-wave light is increased, which is equivalent to a marked sensitivity increase in the blue region. The high carrier concentration which is otherwise present in the p region and which lowers the carrier lifetime, no longer affects the sensitivity. The surface recombination is now the only remaining variable that matters.
Patent DE-3435075-A1 (DE)
Title: Gas generator, process for producing reaction gases and use of a metal hydride and of its reaction gases
Inventor: BUGIEL HORST GEORG DIPL ING
IPC: F02B1/04
Filed: 1984-09-25
Abstract: The invention relates to a gas generator (1), to a process for producing reaction gases (8) and to the use of a metal hydride (sodium boranate 6) and of its reaction gases (8). The invention is based on the recognition that NaBH4 seems to be the ideal reactant for producing large quantities of reaction gas of high combustion energy density, because sodium boranate (6) can be obtained and handled without problems in its powdery/lumpy form and, by simply spraying it with an acid reagent in the presence of water, spontaneously releases quantities of reaction gas (hydrogen) which provide a multiple in yield as compared with conventional propellant charge agents. When spraying sodium boranate (6) with aqueous nitric acid, separate provision of water as a reactant is unnecessary, additional combustion of the hydrogen taking place simultaneously, causing further increase in gas volume. <IMAGE>
