Patent DE-4234745-A1 (DE)
Inventor: IRSCH HANS-PETER DIPL ING
IPC: B28C5/12
Filed: 1992-10-15
Abstract: To produce sprayed concrete, a "lean" cement is not mixed with the aggregate in a mixer but rather brought together with the aggregate immediately before or during pneumatic conveying. In the case of the latter variant, the pneumatic conveying stream is charged first with the binder and then with the aggregate in two feeding stations (1; 2) connected one behind the other. The feeding of the material into the pneumatic conveying stream, with its intensively mixing effects, if appropriate also the mixing effect over the length of the conveying stream, replaces the mixing operation in a mixer. Under these conditions, the aggregate does not need to be dried. The duration during which the binder is subject to the moisture of the aggregate is reduced to seconds. There is no clotting or other disturbances of the conveying and of the mixing with the water at the spray nozzle. <IMAGE>

Title: Centrifugal spinning machine - has reserve pneumatic mechanism to extract yarn from pot during power failure
Inventor: KOLTZE KARL
IPC: D01H1/08
Filed: 1992-10-28
Abstract: By spinning on a centrifugal machine, the yarn is formed into a cake inside a pot, and then withdrawn by winding on a spool raised to the inside of the pot. In the event of power failure on all or any unit, a reserve can be activated to at least bring an empty spool to the end of the traverse tube and withdraw the yarn already produced. ADVANTAGE - The cake of yarn that would otherwise be lost is wound on the empty tube by means of a pneumatic reserve, and inertia of the pot. The yarn connection is made without causing a break.

Title: Device for assisting the exchange of sealing felts in cocoa-butter presses
Inventor: HUEBNER ECKHARD
IPC: B30B9/04
Filed: 1993-05-04
Abstract: The object of the invention is to develop a device by means of which, while maintaining the prestressing of a compression spring, the forces necessary for the deformation work of the sealing felts are applied and the displacement path of the perforated screen plates is lengthened to an extent which permits an obstructed exchange of the sealing felts. This object is achieved in that provision is made for means which, while utilising the maximum prestressing force of the compression spring (9), are in engagement alternatively only with one of the two perforated screen plates (4.1; 4.2) in each case. The invention is used in cocoa-butter presses and assists the time-consuming exchange of sealing felts. <IMAGE>

Title: Protective cap for an NH (low-voltage high-rupture capacity) fuse contact
Inventor: ZIMMER DIETERT
IPC: H02B1/06
Filed: 1993-05-21
Abstract: The invention relates to a protective cap for an NH fuse contact having side walls, a rear wall facing away from the NH fuse and a covering wall and having a continuous gap, which is arranged in the front wall and covering wall, for a contact blade of the NH fuse. This protective cap achieves the object of insertion of the contact blade with a relatively low switching force between the contact surfaces of the NH fuse contact such that the contacts are prevented from being welded to the contact blade and destruction of the switching device is prevented, and the formation of arcs is essentially avoided. This object is achieved in that the mutually facing edges, which bound the gap (6) in the covering wall (3), each have a bead (14; 15) in order to form an insertion chute (13), which bead is designed in such a manner, and is arranged overlapping the free ends of the NH fuse contact, that the unobstructed width of the insertion chute (13) is smaller than the thickness of the contact blade in the region of the overlap, and is larger than the thickness of the contact blade in the region of the insertion opening of the contact blade and, in consequence, in such a manner that the insertion chute (13) can be elastically expanded together with the contact surfaces (F). <IMAGE>
