Patent DE-4029985-A1 (DE)
Inventor: BOHNACKER ULRICH
IPC: B05D1/14
Filed: 1990-09-21
Abstract: In electrostatic powder coating, the starting materials used are metal surfaces which are furnished with an oil film for protection against corrosion during storage and transport. The polymer powder is applied to the surface without removing the oil film. The powder layer is then melted in an oven and is finally cured by cooling. The heat applied by the oven should be sufficient to volatilise the oil. An oil is preferably used which remains stable or resistant during the heating process as long as it remains on the workpiece surface. This includes the possibility that individual components or the entire oil diffuse through the powder layer and evaporate during the heating-up process, or alternatively that part or all of the oil quantity remains on the workpiece during the heating process and mixes with the powder layer. In both cases, the quality of the plastic coating is not adversely affected by the oil film.

Abstract: A machine for attaching and flush milling edge strips on the narrow surfaces of plate-shaped workpieces in continuous operation has a transport device on which the workpieces can be clamped in place in such a way as to project with the relevant narrow side transversely to the passage direction. Furthermore, it has an edge-gluing device and a flush-milling device arranged laterally on the transport device one behind the other in the passage direction. The flush-milling device has at least one milling tool which is made to follow up with its rotational axis transversely to the passage direction and parallel to the workpiece plane and so as to be flush with the top side of the workpiece. Such a machine is to be operable from one location, is to be of compact construction and is to require no additional overall width or no separate conveying mechanism for the return of the workpieces. To this end, the machine works in such a way that, at the end of the passage of the workpiece at the flush-milling device, the milling tool is lowered, the conveying direction of the transport device is reversed and, during the return, the milling tool is made to follow up in such a way as to be flush with the underside of the workpiece.

Title: Spark erosion gap width regulation - with continuous predetermined tool electrode oscillation to eliminate cyclic delay and response to gap information to be accelerated
Inventor: KATHER KLAUS-PETER
IPC: B23H7/28
Filed: 1990-11-23
Abstract: Gap width regulation in spark erosion machining, by means of planetary control in which the tool electrode is adjusted along a three-dimensional trajectory. The tool electrode dependent on the gap information moves continuously back and forth between a nominal trajectory point and a predetermined retraction position. Control of the tool electrode incorporates separate gap and position regulation. Retraction positions can be stored in the memory of the planetary control system. The gap regulation system can be switched at a frequency of at least 20 kH between nominal trajectory and retraction positions. The switching process covers all three spatial axes in chosen order. Both trajectory and retraction positions can be specified as nominal values. The retraction position can be issued as input for the gap regulation system. The planetary control apparatus incorporates an additional device for gap width control. The additional device consists of a control system and three position regulators for storing in memory the retraction positions of three spatial axes of the tool electrode. The retraction positions in the position regulators are adjustable. USE/ADVANTAGE - Allows the cyclic delay inherent in traditional spark erosion systems to be eliminated and the response to gap information to be accelerated. Both the productivity and the quality of spark erosion machining are improved.

Title: Staphylococcal neutral phosphatase and 70 KD protein - isolated by immuno:affinity purificn., ion exchange chromatography or affinity chromatography and used to stimulate lymphocytes and bind immunoglobulins
Inventor: YOUSIF YEHIA MOHAMMED
IPC: C07K16/00
Filed: 1990-11-28
Abstract: A process is claimed for the use of purified active immunoglobulin bound staphylococcal neutral phosphatase and 70 KD protein. The protein is prepd. by (a) immuno affinity purifcn. using antiphosphatase and anti 70 KD protein coupled antibodies on an activated matrix; (b) ion exchange chromatography using cation exchange matrix; or (c) affinity chromatography using immunoglobulin coupled on a solid phase matrix. Stimulation of terminal blood lymphocytes and immunoglobulin synthesis is fulfilled. Sepn. of immunoglobulins, F(ab)'2 fragments and the substrate analogue of phosphatase from solns. is effected by using immobilised phosphatases and 70 KD protein in activated solid phase matrix. USE/ADVANTAGE - Gram positive staphylococcal bacteria are nitrogenic factors for B-lymphocytes. Protein A is not the stimulating factor. In this invention, the purified B-cell stimulation factors, immunoglobulins and F(ab)'2 fragments binding factors are used. The purifcn. process separates phosphatase and 70KD protein from the whole protein soln. Pure phosphatase and 70KD protein can be used as a stimulation factor for B-lymphocytes for immunoglobulin synthesis, both with and without IL-2. Immobilised phosphatase and 70KD protein on an activated solid matrix can be used in the sepn. of immunoglobulin and substrate. The immobilised phosphatase and 70KD protein can bind polyclonal IgG, IgM, IgA and kappa myeloma immunoglobulin both in humans and in rats.

Title: Electrical valve measurer for pin-pointing transients - detects resistance alterations in earth symmetrical or coaxial double cores or voltage drops at appliances
Inventor: GRANDMONTAGNE SIEGFRIED
IPC: G01R31/08
Filed: 1991-02-16
Abstract: Appliances, remotely fed by a constant current, esp. those used for data communication, are integrated in cable systems. At a floating potential, the earth symmetrical or coaxial double core cable, with short time resistance differences (DELTA R (DELTA t)), at the end is looped back via a further current path, as a measurement current path of the same cable. Upon detection of a possible fault in the outer conductor, a remote fed measurement switch (MFSpW) at a floating potential, isolates the ohmic connection of the two outer conductors at the measurement point. The remote feed adaptor (Fsp adaptor) is replaced by a measurement remote feed adaptor (MFsp adaptor) upon occurrence of a resistance-voltage jump in the longitudinal branch of the inner and outer conductor. After fault location, a capacitive voltage divider is made effective between the inner and outer conductors in relation to the fault location, by the capacitive coupling of the measurement loop start (A) across the fault location (X), the far end (B,B') and back (A'). The resistance-voltage jump is distributed reciprocally proportional to the capacitance ratio, and is supplied to the recording measuring unit via isolating capacitors (Cka,b). ADVANTAGE - At non-foreseeable time, occurring resistance differences or jumps, with or without remote feed, are located exactly. Allows automatic measurement.

Title: Prevention of spark erosion of bearings and sliding surfaces - by electric compensation and appropriate choice of materials, useful in engineering field e.g. internal combustion engines
Inventor: EHLEN SIEGFRIED
IPC: F16N17/00
Filed: 1991-03-22
Abstract: Preventing spark erosion of sliding bearings and sliding surfaces with oil film consists of choosing the materials for the metal construction elements so that their potential, in the electrostatic potential series, differs as little as possible from that of the lubricant, and/or drawing off the voltage produced by electrostatic charge in the lubricant layer. The lubricant film is pref. formed by an electrically conductive oil. Carbon particles are used to produce such an oil. The conductive oil passes through a current draw-off chamber. An adjustable negative voltage source is located at a certain distance from the sliding bearing or sliding surface. Its voltage equals or approximates the positive voltage generated by electrostatic charge in the lubricant film. USE/ADVANTAGE - Used in a very broad field of engineering, including internal combustion engines. It enables spark erosion to be avoided or at least substantially reduced and, as a consequence, the working life of sliding bearings and sliding surfaces to be prolonged.
