Title: Increasing propeller-driven ship propulsive efficiency - involves fitting flow guide plates to hull after half parallel to surface and perpendicular to it
Inventor: ANDERSSON GERD O
IPC: B63H5/16
Filed: 1980-11-20
Abstract: The mechanism is used for increasing the propulsive efficiency of propeller-driven, esp. single screw ships. It consists of measures to raise the proportion of boundary-layer water in the flow entering the propeller. Specifically these measures involve the fitting of baffle-plates parallel to the hull plating but clear of it, extending from around amidships to near the propeller. There are bilge-keel type, i.e. substantially perpendicular to the plating surface web plates, extending over much the same length the baffle plates. The ship has an appropriate hull form, with several baffle plates held in position by web plates.

Title: Plate connector for plastics toys - uses transversely resilient pins with two parallel bands giving adjustment between two end positions
Inventor: SCHMID EUGEN
IPC: A63H33/10
Filed: 1980-12-22
Abstract: The fixing between plates in plastics material toys operates with or without locking or clamping. Pins are transversely sprung by two parallel bands, providing to and fro adjustment between two end positions. The spacing between the two end positions limited by the bands corresponds to the height of that end of the pin which in one end position secures a third plate e.g. a container floor against movement. In the other end position, it is sunk into the body formed by the bands e.g. the floor of a box vehicle.

Title: Fastening device for a trim or cover strip, in particular on motor-vehicle bodies
Inventor: STARK KARL
IPC: F16B5/12
Filed: 1981-03-20
Abstract: In the case of motor-vehicle bodies, in particular in the roof region, the joint between two panel parts has frequently to be covered by a trim strip or the like, a channel-shaped gap, suitable per se for inserting a holding body, having to be bridged. Due to tolerances, however, this gap frequently has different widths and it was the object of the invention to produce an adaptable holding body for this gap. This holding body is, according to the invention, of two-part design, the two parts being displaceable along a toothed separation line with respect to each other in such a manner that the outer edges, lying in the direction of displacement, of the two parts move parallel to each other as their spacing changes.

Title: Device for electrothermally atomising an analytical sample
Inventor: FALK HEINZ PROF DR
IPC: F02K1/76
Filed: 1981-05-11
Abstract: A description is given of a device for electrothermally atomising an analytical sample for atomic spectroscopy. Despite low requirements being imposed on the manufacturing tolerances of the components, it makes reproducible measurements possible. It is necessary to construct an atomising body and contact electrodes in such a way that a substantially constant electrical and thermal resistance exists between the atomising body and the contact electrodes. For this purpose contact surfaces are present as spherical zones between the cylindrical atomising body and the electrodes to be received coaxially therewith at its ends. The centres of curvature of the spherical zones lie on the axis of the atomising body between its central plane and the sectional plane of the spherical zones and the outer cylindrical surface of the atomising body. The radius of curvature of the spherical zones is greater than the external diameter of the atomising body and less than half its length.
Patent DE-3124679-A1 (DE)
Title: Bolt combination
Inventor: EVERTZ EGON
IPC: B25C1/18
Filed: 1981-06-24
Abstract: The invention provides a bolt combination for a bolt magazine in a bolt setting apparatus. While known embodiments of the bolt combination make it necessary for the bolts to be arranged inside a plastic strip or the like, in which shearing can lead to inclinations when the bolt is driven out or to damage, the invention is based on the basic idea that the bolts are inserted into the magazine only in a fixed arrangement with respect to one another, from which they can thus emerge without interfering sections of additional material. In this sense, it is provided on the one hand according to the invention that the bolts are connected to one another at their heads by adhesion. On the other hand, the invention also includes the fitment of the bolts to a guide strip in the magazine which encloses the bolts in a C-manner and remains in the magazine while the bolts emerge from the magazine. This ensures that no interfering intermediate sections whatsoever can interfere in the running of the bolt setting apparatus, in one case or the other, and that the bolts are aligned precisely axially in said bolt setting apparatus when they driven in by the impact stamp. Finally, a guide strip which can be pushed out of the magazine with the bolts can also still be used to the extent that said guide strip is broader than the path diameter and a feed gap and an outlet gap for the guide strip are provided in the path. In this case, the guide strip is supported symmetrically with respect to the path axis so that inclination is likewise prevented, while on the other hand the respectively sheared piece of the guide strip forms a buffer between the impact stamp and the bolt head.

Title: Process for producing a coiled hose, and coiled hose
Inventor: BUERCHER FRIEDRICH
IPC: B21C37/12
Filed: 1981-07-31
Abstract: A description is given of structures of coiled hoses with the aid of the production process thereof, according to which, in order to connect neighbouring turns of the coils of the strips of the hose wall material, longitudinally running folds formed in said material are pushed one into the other and, at the point where the folds depart from the hose wall surface, are pressed together, forming a type of neck in cross-section. Depending on the stiffness of the materials used, additional bands have to be used to form an inner fold or an outer fold which runs around in a clamping manner. The fold structure of the inner fold prevents the folds of the hose wall material from slipping out of the stiffer outer fold or the clamp.

Title: Booster charge
Inventor: HELFGEN WERNER
IPC: F42B3/26
Filed: 1981-11-05
Abstract: The present invention relates to a booster charge of compressed secondary explosive, which is characterised by a special geometry. The booster charge contains a conical hollow cylinder into which a detonator or an electrical fuse can be introduced with suction, displacing the air. The walls of this hollow cylinder consist of a material which, though elastic, re-assumes the original shape when the forces acting thereon, for example during the introduction of the fuse, disappear. The walls of the hollow cylinder thus surround the detonator, which has been introduced into the latter, in close contact, similar to the force of a spring. The geometry of the body in which the secondary explosive is located also makes it possible for the secondary explosive to come to lie as a cover above the fuse bottom to be introduced, so that perfect propagation of the detonation is possible.

Title: Process for the production of glass wool from basalt or basalt-like rock
Inventor: MENGEL KURT DR
IPC: C03C13/06
Filed: 1982-06-16
Abstract: In the production of glass wool from basalt or basalt-like rock, the comminuted rock is melted with application of heat to give a melt. The latter is re-shaped with solidification to give glass wool. In order to reduce the proportion of glass beads during the production, the crystallisation of olivine is prevented by reducing the chemical composition of the melt with respect to its magnesium and iron content or by employing from the beginning, as the basalt-like rock, only an alkaline rock which has a low magnesium (Mg) and low iron (Fe) content.

Title: Adjusting device for ski bindings
Inventor: POPEK KAREL DIPL ING
IPC: A63C11/26
Filed: 1982-08-31
Abstract: The adjusting device for ski bindings consists of a base plate to which the ski including binding and boot is fixed and to which a heel ejector for the front release and at least one boot-tip ejector for the torsion release are fastened. The cost of the hydraulics can be considerably reduced, and at the same time the inaccurate force measurement when determining the torsion release value can be replaced by the more reliable torque measurement, if the device is provided with a rotary plate in the heel area of the boot, which rotary plate carries both the heel ejector and the boot-tip ejector and can be lifted by a hydraulic cylinder for adjusting the heel release value and can be rotated in both directions about a perpendicular axis by the same hydraulic cylinder for adjusting the torsion release value. To this end, the hydraulic cylinder can be pivoted over an angular range of at least 180 DEG  about an axis of rotation parallel to the longitudinal axis of the ski in a plane intersecting the longitudinal axis of the ski at right angles. Its piston rod is connected to the rotary plate via a ball-and-socket joint.

Title: Device for viewing photographs
Inventor: LUTZE STEPHAN
IPC: G03B35/18
Filed: 1982-10-29
Abstract: The device is intended to reproduce spatial impressions by means of photography as objectively as possible. Objective reproduction of the spatial impression depends on two conditions: conveying the reproduction of the three-dimensional photograph that is correct in terms of perspective and is possible only if the angular fields are identical during taking and viewing of the photograph (it is also possible in this way to apply extremely large angular fields, that is to say 90 degrees and more). During taking, two images are to be generated by means of two lenses or cameras mounted at the eye separation, or by displacing a camera at the spacing of the eyes. The two photographs must be in one plane during taking. The viewing device (see Fig.) is preferably based on slide projection on a ground glass viewing screen (3). The image planes of the slides and the ground glass viewing screen are parallel. The projection lenses are at the eye separation (P1, P2). Polarisation filters having a rectangularly set polarisation grating are located before the projection lenses (P1, P2) and the eye points (A1, A2). The filters at the eye points (A1, A2) serve as fixed eye pieces. Only photographs taken at the same angular field can be used.   <IMAGE>
