Title: Continuous magnetic filter for separating detectable materials from liquids
Inventor: SCHRIMPF HEINRICH
IPC: B03C1/10
Filed: 1981-11-26
Abstract: The magnetic filter for separating detectable materials from liquids is arranged in a container for high throughput rates, which has feed branches for pulp and filtrate overflows. It can be used for continuous purification of coolants and lubricants and consists of toroidally shaped magnet ring tubes which are arranged vertically at equal distances mutually parallel and are immersed with about 80% of their periphery in liquid and which form, by means of lateral closing walls, the interior of the magnet ring tube, into which the pulp flows through feed branches and, when flowing through the annular gaps, releases the magnetically detectable materials to the surfaces of the magnet ring tubes. These are rotated by drive rollers seated at the upper vortex and the adhering detectable materials are simultaneously cleaned off by scrapers which, as viewed in the direction of rotation, are seated before the drive rollers and surround the magnet ring tubes. The detectable materials which drop off are picked up by a conveyor located underneath. The filtrate flows through the container, whose liquid level is kept constant by the overflows.

Patent DE-3243332-A1 (DE)
Title: Extrusion die
Inventor: DUDLEY VERNON EDMOND
IPC: B29B9/06
Filed: 1982-11-20
Abstract: In an underwater pellet producer which produces plastic pellets from a molten polymer which is ejected through extruder openings or die plate holes and in the process comminuted by a knife arrangement into pellets, thermal inserts which are made of a metal with very high thermal conductivity and are disposed in the die bores are used in order to reduce the thermal gradient that exists between the upstream side and the downstream side of the die plate by conducting heat from the molten polymer plastic at the upstream side to the downstream side and thereby reducing or preventing the risk of freezing off at the extruder openings at the downstream side, which is usually caused by the fact that the water solidifies the molten polymer before emergence from the die plate, so that the extruder opening is partly or completely blocked. The downstream side of the die plate has a layer of a metal of low thermal conductivity, so that the greatest part of the temperature drop, which necessarily must result between the upstream and the downstream side of the die plate, occurs at the downstream side of the plate and not through the complete thickness of the plate. A thin annular air gap is provided between the thermal insert and the body of the die plate in the region of the downstream side of the plate in order to permit thermal insulation between the downstream side of the die plate and the insert of high thermal conductivity. <IMAGE>

Title: Process and apparatus for producing bellows for musical instruments
Inventor: SAUERSTEIN ALBERT
IPC: G10D11/00
Filed: 1982-12-10
Abstract: The invention can be used for making musical instruments involving bellows, such as accordions, harmonicas, concertinas, musical toys. The invention relates to a process and an apparatus suitable for carrying out this process for producing bellows for musical instruments, preferably accordions. Instead of individual corners, continuous corner strips, which preferably consist of synthetic material and are preferably fastened by means of heat-sealing methods, are used for sealing off the corner zone of bellows. In this case, the corner strips are attached at a defined distance from the top of the bellows. By this process, the use of laminated bellows board is made possible and a continuous tube system with air impermeability is achieved. In addition, a high degree of mechanisation can be accomplished, work productivity is considerably increased and high material economy is achieved.
Patent DE-3303881-A1 (DE)
Title: Hydrostatic differential gear with brake energy recovery device for vehicles
Inventor: SEIFERT HANS PROF DR ING
IPC: B60K6/12
Filed: 1983-02-05
Abstract: The invention makes it possible to convert the kinetic energy generated in the deceleration of vehicles into potential energy of a hydraulic accumulator and to utilise this for re-starting. Due to the fact that a differential gear present in the vehicle is replaced by a hydrostatic differential gear, however, no additional transmission components are required for this purpose other than the accumulators themselves and clutches and valves. Since the hydrostatic differential gear is a three-shaft epicyclic gear, in normal drive operation the drive power is hydraulically converted only when cornering and even then only to a limited extent. Fig. 1 shows in diagrammatic form as an example an embodiment of the invention with adjustable displacement volumes of the hydrostatic units. Another embodiment with constant displacement volumes is possible with additional hydraulic control elements. Further additional functions of differential gears such as, for example, free wheel effect, partial or 100% differential lock and the output of varying torques with adjustable torque ratio can be achieved in a novel manner.

Inventor: ZOOR REINHOLD
IPC: A63C9/00
Filed: 1983-02-23
Abstract: A device for releasably holding the boot support of a cross-country ski binding against pivotal movement relative to the ski has a retainer which is mounted on two pairs of mutually inclined links. The lower ends of the links are pivoted to the ski and the upper ends of the links are pivoted to spaced-apart portions of the retainer so as to compel the latter to move along a path which is at least substantially parallel to the upper side of the ski between an operative front end position and an inoperative rear end or retracted position. The retainer can be moved between such positions by a combination of a link which is directly pivoted to the rear part of the retainer and a lever which is fulcrumed on the ski and whose forwardly extending arm is articulately connected to the rear end of the link. The rearwardly extending arm of the lever can be pivoted by hand or by the tip of a ski pole in order to move the retainer to the operative position. The retainer is moved to inoperative position in response to pivoting of the link by the tip of a ski pole. The pin which couples the lever to the link is moved to one side of a dead-center position in response to movement of the retainer to its operative position and to the other side of such dead-center position in response to retraction of the retainer to its inoperative position.
