Patent DE-3834367-A1 (DE)
Title: Special apparatus for deliberately destroying rotor blades of flying, enemy military helicopters
Inventor: BARTH MATHIAS OTTO
IPC: F42B12/66
Filed: 1988-10-10
Abstract: The present invention relates to a special apparatus by means of which, without using units which fire projectiles, the rotor blades of flying, enemy, military helicopters can be destroyed, and the aircraft caused to crash, in a simple and cost-effective manner. The deliberate destruction of the rotor blades without which flight is not possible at all is carried out via linked arms which are intrinsically stiff, are fastened in an articulated manner, extend a long distance laterally, originate from an annular, solid base holder and are fitted with a number of relatively small but very highly effective explosive bodies. As a result of the articulated connections of the linked arms, which extend in the form of rays, on their base holder, they can be bundled. Once this bundle has been released, they extend under the influence of spring force until they are flat in the horizontal direction and assume a position there analogous to the rotor blades. The apparatuses, which are constructed such that they search for targets, are ejected in bundled fashion from dedicated, overflying aircraft and immediately spread on contact with the blades which rotate with the normal flapping movements. A fuze mechanism which is located between the linked arms triggers them only in their fully extended spread state and leads to the detonation of the explosive bodies and thus to the destruction of the rotor blades.

Title: Method for producing a pattern for full mould casting
Inventor: BISSINGER FRIDOLIN
IPC: B29C65/36
Filed: 1988-10-21
Abstract: With the increasing demands made on castings, increasingly complicated patterns capable of being gasified by the molten material are required for full mould casting. At the same time, the corresponding casting patterns can, to an increasing degree, no longer be produced in one piece owing to their difficult spatial structure, but instead a plurality of prefabricated pattern parts must be bonded to produce the finished consumable casting pattern. According to the prior art, so-called hot-melt adhesives and to a lesser degree solvent adhesives are used to bond such patterns, which consist predominantly of foam plastic. During the bonding of foam-plastic pattern parts, the hot-melt adhesives frequently lead either to the adhesive swelling out of the bonded joint or, if attempts have been made to avoid this by means of a thinner application layer, to gaps in the layer of adhesive. Both effects have the disadvantage that, in particular when working with black wash, they cause faults on the surface of the casting in the region of the bonded joint (10). A method for producing a pattern for full mould casting is therefore proposed, in which foam plastic still containing expanding agent is locally after-foamed in the bonded joint (10) by means of heat and the pattern parts thereby become welded together in the region of the bonded surfaces. The local production of heat takes place by means of electromagnetic waves, in particular microwaves, using a means which with the microwaves ... a marked interaction ...

Title: Process for producing carbon mesophases and products of the carbon mesophase-type
Inventor: HUETTINGER KLAUS J PROF DR
IPC: C10C3/00
Filed: 1988-12-10
Abstract: A process for producing carbon mesophases or products of the carbon mesophase-type, such as mesophase pitches from bituminous coal tars or bituminous coal tar pitches, petroleum pitches, aromatics or similar precursors is described, wherein the polynuclear aromatics, capable of forming mesophases, are formed in a continuously operated, fully backmixed stirred kettle reactor (mesophase reactor), i.e. at constant temperature and constant concentration, the precursor or precursors is or are continuously fed in the liquid form and the mesophase or the product of the mesophase-type is likewise taken off continuously in the liquid form. The pressure in the mesophase reactor is in every case above the surrounding pressure. The temperature in the mesophase reactor is at least 300 and at most 600@C. The liquid product taken off from the mesophase reactor passes into at least one further series-connected, continuously operated and fully backmixed stirred-kettle reactor (conditioning reactor) in which the adjustment of the desired average molecular weight or of the desired softening point is accomplished by a further temperature treatment. As a result of this reaction sequence, the process has extraordinary flexibility with respect to the precursor, pressure, temperature, residence time and the application of reactive gas atmospheres or catalysts. On the basis of the constant temperatures prevailing in the kettles and ... Original abstract incomplete.

Title: Submunition which can be ejected from an aircraft
Inventor: GUNDEL BERND
IPC: F42B10/56
Filed: 1988-12-23
Abstract: A submunition is described which can be ejected from an aircraft and is connected by means of a connecting device to a parachute (10; 42) which has shroud lines (12; 43). Undesirable relative rotation between the submunition (14) and the parachute (10; 42) is possible during an initial phase after the parachute (10; 42) has been deployed, and the connecting device has a connecting member (16) to counteract this. The connecting member (16) has radial dimensions which are preferably at least approximately at right angles to the vertical centre axis (22) of the deployed parachute (10; 42), which dimensions can be varied in order to increase the radial separation between the shroud lines (12; 43) and the vertical centre axis (22). In consequence, it is possible to improve the torque transmission from a rotating part of the system to a non-rotating part of the system. In order to achieve the same purpose, the connecting member (16) can be aligned at least approximately at right angles to the centre axis (22) when the parachute (10; 42) is in the deployed state, it being possible for the shroud lines (12; 43) to point away from one another in the same direction, with a radially constant separation. At the same time, a spin line (48) can project from the centre region of the connecting member (16). <IMAGE>

Patent DE-3903342-A1 (DE)
Inventor: BUNZ GEORG
IPC: A44C11/02
Filed: 1989-02-04
Abstract: A plug-type clasp for pieces of jewerly, in particular for necklaces, composed of a housing in which a sleeve is movable under the force of a spring. The sleeve has a receiving opening into which a connecting element can be inserted through a front-end opening of the housing and locked there. Both the front-end opening of the housing and the receiving opening of the sleeve are eccentrically offset from each other, so that the connecting element can only be inserted into the housing, and locked there, only after the sleeve has been pulled back against the force of the spring. Removal of the connecting part can take place in the correspondingly reversed order. Activation of the sleeve for unlocking the plug-type clasp takes place by means of an operating button, laterally guided in a longitudinal hole of the housing, so that the actual connecting areas of the plug-type clasp for pieces of jewelry, in particular necklaces, remain free of pulling stresses during the operation of the plug-type clasp. With the exception of the spring and sleeve, no other movable parts are required.

Title: Disposably based anti-infection system for waste disposal in the medical sector
Inventor: SCHREIBER HORST
IPC: A61B50/36
Filed: 1989-03-14
Abstract: The status of present waste disposal in the medical sector is defective in many places. The number of puncture and cutting wounds caused during disposal is very high in this area. The resulting protective inoculations and after-treatment create enormously high costs for those responsible. Recycling of refuse in the medical sector is unknown. The problem is solved by a combination of a masking plate with insertion apertures and a retaining apparatus in stainless steel design, coloured protective containers with labels, and collection containers as disposable containers. The system minimises the risk of injury to operatives and, by separating the materials, facilitates return for recycling. The design is cost-effective for the user in the long term.
