Patent DE-3615616-A1 (DE)
Title: Separation method
Inventor: HEFFT MANFRED
IPC: B03B5/00
Filed: 1986-05-09
Abstract: Disperse solid material, that is to say solid material consisting of individual particles, usually has a particle size distribution which extends over a broad range. In the further processing or technical use of this material, a narrower particle size distribution is desired. For the purpose of separating the disperse solid material into two fractions, one of which preferably contains particles which are larger and the other particles which are smaller than the particle size selected as the separation limit, the solid material to be separated is first of all dispersed in a liquid. This dispersion is transported counter to the direction of the gravitational force of the earth in a throughflow container which functions as a separation system. At the same time, the flow speed at the separation plane is adjusted such that, for those particles whose size corresponds to the selected separation limit, it is equal to the sinking speed of the particles in the liquid. Two funnels standing upright, which are arranged one above the other and are connected together at their larger opening are used as the separation container. The smaller opening of the lower funnel is used as an inlet for the dispersion liquid and the smaller opening of the upper funnel as an outlet for the dispersion liquid with the separated fine material. Since it is possible to work with relatively high concentrations of solid matter in all particle size ranges, that is to say even below 60 mu , the method is suitable for a preparatory separation.

Patent DE-3703098-A1 (DE)
Inventor: SAILER HUBERT
IPC: F16D55/00
Filed: 1987-02-03
Abstract: The disclosed forced cooling device for friction brakes or clutches eliminates drag torques in friction disk sets (6, 10, 11, 12) which are oil-cooled by providing a reliable stopping of the cooling oil supply at the end of each braking operation. The braking pressure disk (13) comprises at its circumference pipe sections (22) which may be axially driven, designed like piston valves in the front wall (1) of the crank case. By bearing on the pressure springs (28) surrounding them, the pipe sections (22) reliably stop the oil supply sections (26) even in the case of machining or travel tolerances, as soon as the braking pressure disk (13) has come back close to the starting position. Due to these non-rotary pipe sections (22), the cooling oil reaches only during a braking operation, in predetermined quantities and independently of the rotational speed, an inner annular channel (7) acting as an oil retained space situated under the inner disk support (3) provided with radial oil passages (9) between the slots situated between the inner and outer disks (11, 12). The uniform oil retained pressure maintained in front of the oil passages (9) by means of the centrifugal forces during a braking operation makes it possible to obtain a uniform pressurization and speed on all surfaces. It is thus possible to obtain with such a device associated to a plurality of other embodiments of oil channels and sprinkled cooling surfaces a cooling and lubricating effect which increases the useful life of the apparatus with relatively small oil quantities and costs of production and materials substantially reduced.

Abstract: The longitudinally magnetising thin-film magnetic head with a layered structure includes a magnetisable conducting element similar to a ring head, having a first, leading magnet leg and a second, trailing magnet leg, these magnet legs forming two magnetic poles, which are separated by a gap of small width. In the case of this magnetic head, it is intended to suppress during reading an undesired reading of remains of data at the edges of a data track. For this purpose it is provided according to the invention that the magnetic pole (P2) of the second, trailing magnet leg (10) has a width (b2) transversely to the direction of movement (v) which is greater than the corresponding extent (b1) of the gap (13) formed between the magnetic poles (P1, P2) or of a corresponding gap region (29) with the small width (g). <IMAGE>

Patent DE-3811875-A1 (DE)
Title: Guide arrangement
Inventor: SCHILLER GUENTER
IPC: B21B29/00
Filed: 1988-04-09
Abstract: The intention is to make a rolling stand easy to convert for use with work rolls of different diameters. For this purpose, the chocks of the work rolls are guided via guide pieces on rails which allow the vertical changes in spacing to be compensated. It has been found that the guides between the guide pieces and the rails have hitherto been of very short design because of the small amount of space available. This led to tilting. The proposal is to guide the upper guide pieces and the lower guide pieces on separate rails in such a way that they are guided in a nested arrangement over almost the entire clear area between the chocks for the intermediate or back-up rolls.
Patent DE-3813784-A1 (DE)
Title: Erection yoke
Inventor: EICHLER HERBERT
IPC: B66C13/23
Filed: 1988-04-23
Abstract: An erection yoke suitable for multiple crane erection work is created by the invention. With this erection yoke, horizontal and vertical movements of the load take place automatically without correction by the operator. The sequence of movement for the load-slinging block is reliably controlled and the accuracy and safety of the erection process is increased while reducing the erection time compared with the prior art. The erection yoke consists of two remote-controlled drives arranged on a compression member and having two tension elements fastened to a load-slinging block. The drives are equipped with variable-speed, change-pole electric motors and are connected to mechanical or electrical program registers which are mainly designed as spindle switches. The number of program registers coincides with both the speed stages of the electric motors and the number of switching radii of the program registers. The use of the invention is especially advantageous in the erection of parts whose mass exceeds the carrying capacity of the individual lifting appliances available. <IMAGE>
