Patent DE-3806708-A1 (DE)
Inventor: SCHUBERT CHRISTOPH DIPL ING
IPC: C02F1/48
Filed: 1988-03-02
Abstract: A plurality of magnet systems are attached from outside to a selected part of the pipe system in such a way that these magnet systems hold one another closely against the pipe without requiring any holding parts. The magnet systems consist of half shells which are equipped with permanent magnets or electromagnets of opposite polarity. This results in pole faces on the half shells which cause the parts to mutually adhere around the pipe. <IMAGE>

Title: Device for guiding and directing spraying wires in electric-arc spray guns
IPC: C23C4/131
Filed: 1988-03-15
Abstract: The invention relates to a device for guiding and directing spraying wires in electric-arc spray guns, the wires being directed to the short-circuit point via guiding rollers and guiding devices and being contacted electrically via contact means. With a device of this kind the intention is to provide a solution with which the guidance and contacting are substantially improved. This is achieved in that for each wire a plurality of rolling members are provided on the wire-guiding path, which rolling members guide the wire about its axis in a manner such that it is secure against twisting, the rolling members being mounted such that they are insulated electrically. <IMAGE>
Patent DE-3808621-A1 (DE)
Inventor: KLAPETTEK GERHARD
IPC: B65H1/04
Filed: 1988-03-15
Abstract: A pile receiver should be vertically adjustable in order to adjust the level of the surface of the pile of sheets for printing and should be safely guided during the vertical movement despite a heavy load. Economical guiding is achieved by designing the stationary frame of the pile receiver as guide rails (4) arranged flush with a front wall (2) of the pile receiver. The front wall (2) of the pile receiver forms a carriage on which laterally projecting receiver supports (3) are mounted. The carriage (2) is doubly guided in a torsion-free manner in the two guide rails (4). The carriage (2) is adjusted vertically by means of a chain drive (12, 16, to 21) comprising a stationary chain (12) arranged in each guide rail (4). The pile receiver can be used as a sheet feeder or sheet collector in single-sheet printers.

Title: Modulo-10 counter which supplies the counter state in 51111 code
Inventor: MERKLE PAUL
IPC: H03K23/50
Filed: 1988-04-11
Abstract: The modulo-10 counter according to the subject of the invention differs from the modulo-10 counter according to P 3800441.0 in that the negating circuits (22) and AND circuits (23) are not arranged, and that, only for the middle triggering of the OR circuit (40), such a blocking circuit, which consists of the negating circuit (24) and the AND circuit (25), is arranged. The decades thus supply the decade counter state in 51111 code, not 54321 code. <IMAGE>

IPC: C03B19/10
Filed: 1988-07-05
Abstract: In a process for obtaining spherical solid particles for use as beads for shot-blasting, fillers for plastics or reflector beads, the fly ash from the melting chamber furnace (3) of a coal-fired power plant (1) is separated in an electrostatic filter (12) and removed. The ash, which is removed mainly from the preliminary stage (20) of the electrostatic filter (12), undergoes several sorting processes in which particles of the correct particle size (22), weight (24), and surface shape and/or structure (26) are selected. The selected spheres are then subjected to a heat treatment to relieve internal stresses. Ash residue can thus be used in order to manufacture a high-grade spherical bead material for shot-blasting.
Patent DE-3826033-A1 (DE)
Inventor: BOSTEL KARL-HEINZ
IPC: B29C45/14
Filed: 1988-07-30
Abstract: The invention starts from a method of manufacturing elastomer stators, the elastomer of which shrinks after the stator has been finished. In order to increase the precision of the pump cavity, this space is initially made larger and wider. The metallic, annularly continuous casing externally surrounding the stator is then reduced in outside diameter, e.g. by means of a die. In this procedure, the elastomer is compressed radially in order in this way to bring the pump cavity to a precise internal dimension as a function of the diameter reduction, the internal dimension thus being independent of the shrinkage.

Title: Control system with adjustable valve timings for four-stroke engines
Inventor: MAGER GERD
IPC: F01L13/00
Filed: 1988-12-15
Abstract: In order to increase the peak power output of four-stroke engines whilst at the same time improving the torque at low engine speeds, the valve timing is no longer performed with a constant opening angle, but designed so that an optimum timing angle can be set at any speed in an infinitely variable manner. This is achieved in that the separate, continuous camshaft is replaced by a system of short, coaxial separate cams, in which two cams act independently of one another on each catcher (rocker arm, valve lever or tappet). The partial camshafts are driven by way of two intermediate shafts, so that, however, only non-directly adjacent partial camshafts are driven from the same intermediate shaft. The overall opening angle can be increased by a phase offset between the two intermediate shafts and hence the adjacent partial camshafts.

Title: Rapid indexing mechanism for machine tools - has hydraulic drive giving constant acceleration to mid-point of index followed by constant deceleration
Inventor: KLETT MANFRED
IPC: B23Q16/02
Filed: 1989-07-22
Abstract: As applied to a rotary table indexing machine, the indexing mechanism consists of one or more hydraulic motors (36, 604) with a pinion (40) driving onto an internal ring gear (44) on the underside of the table (14) of the machine.  The machine may typically have six work carriers (16) equally spaced around the table and aligning with say five machining stations and a load and unload station. A cam on the underside of the table controls the admission of oil to the motors (36,60a). The table is held in position against retractable stops (108) actuated by the overall machine control system. The shortest possible indexing time is achieved by applying a constant force to the table and releasing the stops (108). The table moves with constant acceleration to the midpoint of the  index, when the force is effectively reversed so that the table comes under constant deceleration until the index is completed and the table comes up against the stop. USE/ADVANTAGE - Fast index increases machine productivity.

Title: Quantitative fractionation of biological material - using fanned-out magnetic field

IPC: G01N33/543
Filed: 1989-07-28
Abstract: The quantitative fractionation of biological material (cells, organelles, chromosomes, viruses etc.) attached to magnetic beads is effected in a magnetic field.  This material is supplied to the separating chamber in a suspension and floats in the latter on a buffer liq. through the magnetic field which is inhomogeneously fanned out and fractionates the beads. A buffer liq. pref. descends from the feedpoints (141) in the separating chamber (1) and the suspension is injected form the inlets (401) at a speed (v).  The magnetic assembly (2) with the iro core (22), the winding (21) and the steel plate (23) produces the magnetic field (H) which distributes the beads over the test tubes (151). ADVANTAGE - A continuous system which deflects the magnetic beads according to their magnetic moment.  The biological material is treated very gently.

Title: Producing co-extruded thermoplastic film with less expense - using undried outer polymer within specified range of intrinsic viscosity, degassing in extruder and combining with second polymer at nozzle
IPC: B29C48/08
Filed: 1990-03-26
Abstract: A co-extruded film is produced with at least one outer and one base layer; the outer layer polymer comes from the gps. of polyester homo- and co-polymers, mixed polyesters or mixed  blends of polyesters and other polymers. In the process the skin layer material used has an intrinsic viscosity IV of 0.49-0.66 and it is fed in to the extruder without having been dried; it is degassed during the extrusion, and the extruded prod. is discharged by a gear pump through a filter to the nozzle concerned with or without using a torpedo, and the base layer is fed in to the nozzle area. ADVANTAGE - The procedure eliminates the expensive process of drying the outer layer polymer. This partic. polymer nevertheless suffers minimal degradation. The two polymer layers combine with stable flow streams. The outer polymer can utilise relatively low viscosity material and this reduces costs.
