Title: Mobile rope winch
Inventor: BECHMANN PETER
IPC: B66D3/00
Filed: 1981-09-24
Abstract: The smooth casing of a motor-driven rope drum of a mobile rope winch is of conical design with an angle of slope corresponding to the angle of friction between the load part and the rope drum, and, instead of the rope end being secured to the rope drum in a conventional manner, a clamping disc is provided which is driven in synchronism with the rope drum and via which the rope length pulled off the casing end of smaller diameter is deflected in the direction of a rope magazine. Due to the conical design of the casing of the rope drum, the load part only undergoes single-layer winding so that it can have an unlimited length for fetching a load.

Title: Device for holding and releasing a flap wing of a fire-protection flap
Inventor: MUELLER GOTTFRIED
IPC: A62C2/24
Filed: 1982-01-22
Abstract: In a device for holding and releasing a flap wing of a fire-protection flap, which is preloaded into its closed position, a holding member, which holds the flap wing in its open position, is according to the invention acted upon both by a release bolt held by a soldered security device and by a release lever held by a direct-current magnetic clamp. The release bolt and the release lever can independently of one another move the holding member into its position which releases the flap wing. The flap wing can thus be released not only by the effect of heat inside the fire protection flap but also e.g. by a distant smoke alarm. As the closing force of the flap wing acting on the holding member is directed perpendicularly to the pivot movement of the release lever and because of the lever ratio of the release lever, a weak magnetic clamp can be used which can also be fed from an emergency power supply.
Patent DE-3203366-A1 (DE)
Title: Modular building system
Inventor: MENGERINGHAUSEN MAX DIPL ING D
IPC: E04B1/343
Filed: 1982-02-02
Abstract: The invention relates to a modular building system comprising profiled bars for the construction of a framework skeleton without node pieces and space-closing panels to be arranged in the skeleton gaps. Known constructions of this type are complicated to assemble and moreover have the disadvantage that the panels do not contribute to stabilising the framework skeleton. The invention solves this problem by the following combination of features: each three or four profiled bars (1) having at least one groove (11d) in a plane longitudinal side and having detachable couplings at the bar ends bound the gaps in the framework skeleton; each panel (30) is non-detachably enclosed by a frame, in the form of a triangle or quadrilateral, formed from profiles (301) which has webs (302) projecting outwards in the panel median plane; these webs (302) engage in grooves (11d) of the adjacent profiled bar (1, 2) in such a way that the edge of the frame laterally of the webs (302) is pressed on all sides against the outer faces (303) of the profiled bars (1, 2). As a result, at the same time as the positive engagement, a non-positive engagement for the mutual force of transmission between the panels and the profiled bars of the framework skeleton is also obtained. The main application of the invention is in the construction of partition walls and light spatial constructions, such as for example, advertising towers, camping homes and the like. <IMAGE>

Title: Appliance for the metered dispensing of masses
Inventor: HERB ARMIN
IPC: G01F11/02
Filed: 1982-08-31
Abstract: Appliance for the metered dispensing of putty-like or pasty, single- or multi-component masses, in which the piston rods (6,7) are surrounded over a portion of their length by a sleeve (8) containing a body (9) of elastically deformable, incompressible material. By actuation of the hand lever (11), the body (9) is placed under pressure via an expulsion plunger (14). The pressure propagated on all sides effects a connection of the sleeve (8), or of the body (9), to the piston rods (6,7). On actuating the hand lever (11), the piston rods (6,7) are thus transported in the extrusion direction. When the hand lever (11) is released, the connection between the sleeve (8), or the body (9), and the piston rods (6,7) is interrupted again. <IMAGE>

Title: Interchangeable container with an ink reservoir chamber for an ink printing unit
Inventor: MARTENS HORST
IPC: B41J2/175
Filed: 1982-10-14
Abstract: Interchangeable containers (23) with ink reservoir chambers (25) for ink printing units can only be used after a relatively long period of storage if they have a low degree of permeability to gas and water vapour. The invention is based on the object of providing interchangeable containers (23) which can be stored and have a simple and cheap design, without the serviceability of the ink printing unit being put at risk after a relatively long period of storage. This is ensured according to the invention by providing two housing parts (45, 47) with symmetrically constructed chamber halves (31, 33) worked into their dividing plane and a diaphragm (29). This diaphragm (29) is connected to a housing part (47) in a gas-tight and fluid-tight manner and has a deep-drawn preform (59) which when the ink chamber (25) is fully filled rests against the wall (61) of the chamber half (33) with the opening (43) to the atmosphere and when the ink chamber (25) is empty rests free of folds against its wall (63). As a result, the gas permeability and water vapour permeability of the interchangeable containers (23) are considerably reduced, as a result of which long-term storage stability is ensured. <IMAGE>

Title: Pressurised-water reactor having a reactor pressure vessel
Inventor: SANDER MICHAEL DIPL ING DR ING
IPC: G21C9/012
Filed: 1982-11-06
Abstract: There is a flow of primary coolant in the direction of the arrow through a reactor core (1) arranged in the reactor pressure vessel (2). Only a deficient circulation and cooling still takes place in the space bounded by the closure head (3) in the event of failure of the pumps installed in the part of the primary circuit extending outside the reactor pressure vessel. In order to avoid the formation of steam in this space, water is fed via the spray nozzle (8) into the space bounded by the closure head (3) after failure of the pumps which serve to circulate the primary coolant. The coolant line provided for this purpose leads from a vessel (10) into the space bounded by the closure head (3). A pump (9) with an appropriate delivery head is provided to generate the feed pressure. <IMAGE>
Patent DE-3244778-A1 (DE)
Title: Spontaneously crimping multicomponent chemical fibres
Inventor: SCHAEFER KLAUS DIPL ING
IPC: D01F8/04
Filed: 1982-12-03
Abstract: The invention relates to spontaneously crimping chemical fibres which are spun as multicomponent fibres, stretched and then processed to give crimped continuous fibres or staple fibres. It has been discovered that crimped fibres can be produced very simply by spinning, in addition to the thermoplastic base polymer, a thermoplastic second polymer related to this in type, which is present in the form of a copolymer, block polymer or mixed polymer and is modified with respect to the base polymer in such a way that it has an elastomer-like deformation behaviour. The crimping of the threads takes place with increasing stretching and is spontaneously visible on relaxation of the threads. It is based on the different mechanical/physical deformation behaviour between elastomeric and thermoplastic chemical fibre polymers. Crimping takes place as a result of an entropy stabilisation of the molecular chain of the modified polymeric material in contrast with an enthalpy stabilisation of multicomponent fibres, which is based on a different shrinkage behaviour. The crimping of the chemical fibres according to the invention can be made virtually irreversible by a thermal treatment under tensile stress.

Title: Shaft comprising two shaft sections which can be separated from each other
Inventor: REIFENHAEUSER TONI
IPC: F16K3/02
Filed: 1983-04-13
Abstract: A slit (9, 9') between two shaft sections (1 and 2) for receiving a gate valve (3) is sealed off by a sealing element (11, 11'), which can be displaced or elastically deformed perpendicularly to the plane of the gate valve (3), for as long as the gate valve (3) is outside the slit (9, 9'). If the gate valve (3) enters the slit (9, 9'), its front edge, which is provided with a bevel (5), causes it to dislodge the sealing element (11, 11'), which on account of its elastic deformability or on account of its displacement performed under pressure perpendicularly to the plane of the gate valve (3), blocks the cross-section of the slit (9, 9') again when the gate valve (3) emerges from the slit (9, 9'). <IMAGE>

Title: Method for installing an axial compensator, and an axial compensator
Inventor: NONNENMACHER WILFRIED
IPC: F16L51/03
Filed: 1983-08-23
Abstract: Compensators, especially axial compensators, are intended to be subject during installation to prestressing which is dependent on the installation temperature, in order that, in operation, they are loaded to the same extent by both high temperatures and low temperatures. In order on the building site to be able to define in a simple manner the favourable structural length with respect to the expansion object of the compensator and its optimum operation, and to enable it to be installed in a corresponding manner, a method for installing axial compensators using, inter alia, bellows, which are loaded with external pressure, in a pipeline, especially a remote-heating line, different temperature conditions is proposed, in which the bellows, which are loaded with external pressure, and hence the compensator is prestressed for installation via a valve, by setting its internal pressure to the length corresponding to the installation temperature, and the valve is rendered permanently ineffective after installation. A compensator for using this method, having a bellows (9) which are loaded with external pressure and whose internal chamber (14) surrounded by the bellows (9) can be connected via a connection (3) to the atmosphere, has a valve (15) in order to use the method. <IMAGE>
