Title: Self-cleaning of compact sedimentation separators - sedimentation pipes, plates etc. by bodies made of e.g. rubber which are moved back and forwards by mechanical or hydraulic means
Inventor: KUNZ PETER PROF DR
IPC: B01D21/00
Filed: 1991-09-13
Abstract: In the appts. for the sepn. of solids from fluid media by means of a compact sedimentation system, the sedimentation elements are self-cleaning. The appts. consists of an inlet holding container (B), a system of inclined sedimentation elements (A), a control system (E) and a container (C) for receiving the sediment recovered. The sedimentation elements consist of inclined or horizontal pipes, plates, corrugated plates or similar components and can be closed at one or both ends. Self-cleaning takes place by means of cleaning bodies made of easily compressible materials, such as foam rubber balls, rubber cylinders etc., and which can be introduced into, and removed from, the sedimentation elements. These cleaning bodies can be moved up-and-down mechanically or by a fluid under pressure. The self-cleaning procedure takes place while the unit is in operation and is controlled by a sequential switching system. USE/ADVANTAGE - For sepn. of solids from fluids, such as in the sepn. of contaminants from waste water, sepn. of oils from emulsions, etc.. The unit operates efficiently without the need to increase the angle of inclination of the sedimentation elements, and these elements are cleaned automatically without interrupting the continuous operation of the unit.
Patent DE-4133979-A1 (DE)
Inventor: GRUNDMANN RABAN DR
IPC: C08L95/00
Filed: 1991-10-14
Abstract: The polymer-modified bitumens contain from 0.5 to 10 parts by weight of functionalised polyoctenamer per 100 parts by weight of bitumen and are distinguished by particularly good adhesion to the filler material. Even with a relatively small amount of the modifying components, the mixtures have remarkably good low-temperature flexibility, which is evident from a very low breaking point. A further advantage is the high elastic resilience before and after heating. In addition, the homogeneity of the products after storage at elevated temperature should be emphasised. The polymer-modified bitumens are therefore used in road construction and civil and underground engineering as hot binders or in the form of bitumen emulsions for gravel, pebbles, sand and crushed rock. A further preferred area of application is in bitumen-containing waterproofing materials for roofing, especially in the form of webs or sheeting.

It is then fed by a second corner in keyed engagement along the front edge (2) to co-rotating stops (10) where it is finally moved correctly aligned into the machine. The grippers (7) which are attached to a draw head  (8) constantly rotate with the synchronously rotating stops (10) and locally fixed brushes (12). USE - Orderly alignment and conveyance of sheets without interruption.
Patent DE-4137379-A1 (DE)
Inventor: WAREK MICHAEL
IPC: B29C53/80
Filed: 1991-11-13
Abstract: A method is disclosed for manufacturing an elongated workpiece from fibre-reinforced curable material such as synthetic resin. The procedural steps involved are: arrangement along one rotational axis of rotatable and linearly adjustable pick-up devices for the reinforcing fibres at the extremities of the elongated piece being manufactured; configuration between the pick-up devices of a moveable cradle from which the reinforcing fibres can be taken up to the pick-up devices (this step may also include impregnation of the fibres with a curable material); axial and radial laying down of the reinforcing fibres running between the pick-up devices and impregnation of those fibres with the curable material to produce a woven tube impregnated with the material; and curing of the material. The axial laying and stretching of at least an initial axial layer of fibres (which can if necessary be complemented by the subsequent laying of a second, radial layer) is done without any predetermined shape to produce an impregnated fabric tube corresponding to the desired shape of the piece, which can after curing serve as the winding spindle for further layers of fibre.

Title: Open=ended spinning machine - has a fibre delivery channel with a curved elliptical end aligned to the rotor groove
Inventor: MEIER WOLFGANG
IPC: D01H4/38
Filed: 1992-07-11
Abstract: An open-end spinning machine has a fibre delivery passage to provide separate fibres into the rotor. This has pneumatic assistance, and is sealed to the front of the rotor by a cover. The delivery passage is curved with a narrowing channel at the rotor end, in accordance with the size of the rotor. An opening roll produces separated fibre from the sliver, and this is drawn by the pneumatic action into the rotor, along the delivery passage which runs through the cover to seal the rotor. At the end of the passage, the cross section is reduced and it begins to curve, according the diameter of the rotor, and at the same time, an eliptical end is formed. ADVANTAGE - The design of the fibre delivery passage obtains an improvement in the quality of yarn produced, and the yarn has a closer integrated formation.

Title: Weft preparation appliance for weaving loom - utilises hook to release free end of yarn from reserve winding on tube projection of cone
Inventor: BOLT HANSPETER
IPC: D03D47/34
Filed: 1992-08-03
Abstract: Equipment to take up the free end of yarn from a reel which is wound on the end projection of the tube. The reel is held on a spindle as the yarn release mechanism is brought close to in axial alignment. A hook is held to the surface of the tube projection, and revolved as the reel is turned, so that the point of the hook releases the yarn and engages it in the hook. It is then drawn away from the reel, taking yarn from the main winding. Typically the cone (2) is wound on a tube (15) and held on the spindle (40) of a transport system (11). The projecting end of the tube (15b) has the reserve winding (16b) of the yarn (W). A hook (23) is mounted on a bracket (38) in such a manner that it can be revolved around the tube projection (15b). The point of the hook is taken by rotation, so that the yarn (W) engages in it at some point, usually during the first revolution. The hook draws level with a bar, which seals the hook, and the bracket (38) withdraws along the guide (41). The yarn can then be drawn over end by pneumatic device (26). USE/ADVANTAGE - The equipment releases a free end of yarn from a cone which will be used on a loom as weft. The success rate of finding the free end of yarn with a mechanical method is higher than with pneumatic means, where the elasticity of the yarn sometimes springs away.
