Title: Process for keeping constant the wire or cord tension in stranding machines and device for carrying out the process
Inventor: SAEBEL WILFRIED ING GRAD
IPC: D07B7/02
Filed: 1981-10-03
Abstract: In a stranding machine for wires or cords, the mechanical tension prevailing in each wire or each cord is determined by a measuring device which supplies an electrical output signal corresponding to the tension. In order to keep the strand tension constant automatically, the output signals are compared with a desired value in a respective comparator circuit. The difference is transmitted in the form of electrical control signals to the electromotively driven braking devices of the individual reels, and the braking torques are each varied in such a way that the tensions in the individual strands are always approximately constant.

Title: Fire protection flap
Inventor: LAUMEN MICHAEL
IPC: A62C2/12
Filed: 1981-10-08
Abstract: It is the object of the invention to provide a fire protection flap which has a low flow resistance and low flow noise even at high flow velocities. A flap wing (7) of a fire protection flap (3) is mounted for this purpose in an axial bearing (16) traversable vertically in a guide slot (17). In the open position of the fire protection flap (3), the flap wing (7) is moved upwards against the upper wall of a housing (4). The flap wing (7) thus forms an extension of the walls of an air duct (2). The air resistance and the flow noise are therefore not increased relative to the air duct (2) in the region of the fire protection flap (3). On release of a locking device which holds the flap wing (7) in its open position, the latter drops into a central position and is then turned into its vertical closing position. During this, a straight-way valve (22) is opened and an extinguishing agent (25) is pressed from a pressurised container (24) into the space between the plates (12, 13) forming the flap wing (7). As a result, the fire resistance of the fire protection flap (3) can be increased and a seal can be achieved between the housing (4) and the flap wing (7). <IMAGE>

Patent DE-3208399-A1 (DE)
Title: Impact grinding mill for cereals
Inventor: JOHANNING HERMANN
IPC: B02C13/286
Filed: 1982-03-09
Abstract: The invention relates to an impact grinding mill with blower, in which cereals are carried along into the grinding space of the mill by the conveying air sucked through the supply by the mill blower. At the same time, the carrying-along of cereals by the starting-up of the mill is initially inhibited by the sucking-in of supplementary air through an opening in the part, with a widened cross-section, of the connecting piece, or of a pipe, which runs from the sloping part to the grinding space, and cereals are only carried along out of the sloping part shortly before the full blower speed is reached, the amount of said cereals increasing up to the point at which the full blower speed is reached but also being matched to the mill power by means of the supply of supplementary air. Then, in order to avoid overloading of the mill, a second, closed supplementary air opening in the end side of the housing is opened to a greater or lesser extent by the quantity of material for grinding circulating in the grinding space so that supplementary is sucked directly into the grinding space and the quantity of conveying air which erodes the slope is reduced. By virtue of the widened cross-section, after the switching off of the mill, no further material for grinding is sucked in even after a relatively small drop in the blower speed.

Title: Clamping assembly systems for releasable and switchable connections
Inventor: RUEHLEMANN JOACHIM
IPC: F16D27/10
Filed: 1982-04-20
Abstract: The invention proposes a clamping assembly and a clamping-assembly system which allows the construction of clamping assemblies and switchable couplings. The two-path clamping assembly has two regions with different tasks. While the region unslotted in the circumferential direction undertakes centring tasks, with the proviso that the wall thicknesses of this region are optimised for this task, the other region undertakes the task of efficiently converting the screwing forces into surface pressure by means of pairs of expanding tongues. On the basis of two mutually complementary sheet-metal profile rings, so-called expanding rings, the clamping-assembly system allows the production of clamping assemblies for high loads. Clamping and centring tasks for a shaft or a hub can be undertaken with just one expanding ring in combination with a feather key. Expanding rings can be sensitised, allowing them to be used as switchable elements in couplings.
Patent DE-3215950-A1 (DE)
Title: Cutting assembly for passing machines
Inventor: FEURING WALTER
IPC: B02C18/36
Filed: 1982-04-29
Abstract: The invention relates to a cutting assembly for passing machines, which has, rotating between stationary perforated discs, at least one cutter disc with a number of cutter bars. These cutter bars previously had a shovel-shaped cross-section and the hollow side, which acts only partially as a pushing surface for the product to be sliced, tended as a result of the bend to push the product to be sliced through the next inclined perforated disc only incompletely. The product to be sliced remained hanging on the hollow side, was able to heat up and smeared, which meant a loss of quality and a reduction of the throughput. According to the invention, the pushing surfaces (21) for the product to be sliced are designed as plane surfaces between front and rear cutting edges (19, 20) of each cutter bar (17) and adjusted, in relation to the axes of the inclined passage holes (22) in the rear perforated disc (14), at an angle ( alpha ) of approximately 90 DEG  or more. These pushing surfaces (21) push the product to be sliced very forcefully and completely through the next perforated disc (14) even if the meat types are soft and/or fat. <IMAGE>
