Patent DE-3837786-A1 (DE)
Title: Improved metal container with an air-tight lid
Inventor: LLOBET GINES LLAMAS
IPC: B65D43/04
Filed: 1988-11-08
Abstract: The container (1) according to the invention has, on the outer edge of its opening, an upper, curved part (6) which continues in a downwardly expanding shaped outer region in order to form a wide, curved region in the lower part. Below this edge the side surface of the container (1) is provided with an annular projection (10) which defines an inner, very open, U-shaped channel. The lid (2) of the container (1) has a considerable depth and forms a basic disc from which there rises vertically an annular ring of considerable height. This lid (2) has the feature that its outer side wall is provided with a multiplicity of projections (12) which are situated at the same spacing from one another, are extended in the direction of the circumference and have a very wide, angular profile. These projections (12) supplement the inner and annular channel of the container (1) so that when the lid (2) is connected firmly on the container (1) a clamping-type closure is obtained between the lid (2) and the container (1). The lid (2) has a seal (5). <IMAGE>

Title: Anchorage pin for dental restorations
Inventor: STROBL WALTER DR
IPC: A61C5/35
Filed: 1988-11-23
Abstract: In order to impart a natural translucent appearance to pin-anchored dental restorations, the anchorage pins also have to be translucent. This is made possible in that they are no longer produced from a metal, as has hitherto been conventional, but instead from a plastic which possesses the required mechanical strength as a result of incorporated reinforcing fibres.

Title: Cupola-shaped building roof which can be opened
Inventor: FRASE JUERGEN
IPC: E04B7/16
Filed: 1989-01-11
Abstract: It is known to assemble a cupola-shaped building roof from a plurality of roof segments having different radii of curvature, some of which are arranged in a stationary manner and some of which, in order to open the building roof, can rotate, beneath the stationary roof segments, about the vertical central axis of the cupola. The rotatable roof segments are mounted, by means of their base-side border, on rails via wheels and, at their vertices, are suspended, such that they can rotate, at the free ends of a load-bearing structure which engages over the cupola roof from the outside. In order to avoid this high-outlay, overhanging load-bearing structure, the invention provides, at the free lateral border of the roof segments 1, 2, correspondingly curved border load-bearing members 6a, 6b which reinforce the framework of the roof segments 1, 2 to provide a self-supporting structure. <IMAGE>

Title: Utilisation of power of sea waves aboard ship - involves set of hinge blades oscillated by action of waves
Inventor: ERDOGAN HASAN
IPC: B63H19/02
Filed: 1989-05-24
Abstract: The mechanism utilises the power of sea waves which impinge against a ship.  A long blade (2) like a rudder is mounted on a vertical shaft so that it can swing in the horizontal plane under the force of the sea waves. The vertical shaft drives a dynamo through a train of gears and a double free-wheel so that the dynamo is always driven in the same direction irrespective of the direction in which the blade (2) is driven by the waves. USE - Utilisation of wave power aboard ship.

Title: Sealing strip for flat roof - in which extruded plastic strip is more easily welded to roof sealing sheet and gives more consistent joint
Inventor: SCHLUETTER ALOYS
IPC: E04D13/15
Filed: 1989-06-16
Abstract: An edging strip for sealing a flat roof, is described.  The strip is produced from an extruded plastics strip which can be welded more easily to a plastics sealia sheet than a  traditional metal strip.

IPC: F16H48/26
Filed: 1990-07-16
Abstract: The hydraulically self-locking planetary gearbox has in the gearbox body for one or both directions of rotation of the pumping wheel pairs at least one axially movable throttle element which comprises a combination of sealing member with throttle section which always releases a constant throttle cross-section with a throttle length which is variable with the stroke, and offers to the inner pressure in the throttle phase the same engagement surface as in the closed position. The throttle element is connected to one or more chambers which are impinged with a lock-producing pressure with this direction of rotation, and to at least one pressure-less chamber.  On reaching a preset speed-proportional conveyor stream, operated solely by the pressurised oil, the throttle element is completely closed.

Patent DE-4032402-A1 (DE)
Title: Knitter yarn feed - has controlled yarn retraction to form a yarn reserve during a temporary break in the knitting e.g. slide direction change
Inventor: CONZELMANN FRITZ
IPC: D04B15/44
Filed: 1990-10-12
Abstract: The yarn control system for a textile machine such as a flatbed knitter, where the yarn consumption rate changes rapidly during knitting, forms a yarn reserve length before it is taken up for knitting. When the yarn delivery to resumed, after knitting has stopped temporarily, a start signal for the yarn retraction is generated independently of the yarn tension measurment. On receipt of the signal, the yarn retraction action is increased and starts to build up a reserve, and the reserve build-up ends at the latest as stitch knitting resumes. While the yarn reserve is being formed, the yarn tension is held below a preset max. value. As knitting starts, the yarn brake and the yarn retraction unit are controlled to bring the yarn tension to the nominal value and release the yarn reserve. ADVANTAGE - The method ensures that the yarn tension is held at a constant level when taken up for knitting, after a temporary break such as on a direction change by the flatbed knitter slide.
Patent DE-4034249-A1 (DE)
Inventor: PROTZER HELMUT DR
IPC: C23C22/00
Filed: 1990-10-27
Abstract: For the controlled large-scale production of a uniform and firmly adhering brown covering layer (brown patina) on surfaces of semifinished copper products, especially on rolled strip or sheet for the building sector, the process according to the invention provides for first roughening the surface of the semifinished copper product by mechanical treatment and then subjecting the semifinished copper product to a heat treatment for a period of 0.1 to 30 minutes at a temperature within the range from 150 to 650 DEG C. 
<??>This method makes it possible to provide semifinished copper products preweathered in the works, without having to wait for the brown surface discolouration which depends on the long-term action of atmospheric influences. 
<??>For a further improvement in the adhesive strength of the brown patina, the semifinished copper product can advantageously also be subjected to a chemical further oxidation after the heat treatment.
