Patent DE-19833593-A1 (DE)
Title: Selective metallization of e.g. ceramic, glass or plastic, e.g. for circuit board or electromagnetically screened housing, comprising mechanically depositing seeds on a rough substrate surface and then chemical plating
Inventor: VOIT GABRIELE
IPC: C23C18/22
Filed: 1998-07-25
Abstract: A selective metallization process, comprising mechanical deposition of seeds on a rough substrate surface and then chemical metal plating, is new.  Preferred Features: The substrate surface has an average roughness depth of 0.01-100 microns , achieved by sand blasting or plasma or chemical etching. The seed material has a lower hardness than the substrate and consists especially of copper, silver, gold, nickel or palladium. The seeds are applied by linear, vibrational or rotational frictional contact with the substrate surface, especially automatically using a numerically controlled (NC) machine. An exchange reaction may be carried out using a more noble metal, especially silver, gold or platinum, prior to plating. The plated metal may be electrolytically thickened especially with copper, nickel or tin.

Patent DE-19849429-A1 (DE)
Inventor: RITTER HANS JUERGEN
IPC: F16F9/42
Filed: 1998-10-27
Abstract: The invention relates to a high performance vibration damper (1) with a dual acting piston (23) movable in a sealed sliding manner in a tube (36). The piston (23) acts upon a fluid in the working chambers (A, B) by means of forced fluid circulation and displaces said fluid for damping a shock by means of a nozzle device (38) in such a way that the vibrational energy is converted into heat. According to the invention, the fluid thus heated is fed to a cooling device integrated into the high performance vibration damper (1). Said cooling device is configured as at least two chambers (C, E) located between the vibration damper housing (32) and the tube (36). The at least two chambers (C, E) interact with a suction channel provided for the working chambers (A, B) by means of at least one throttling device. The high performance vibration damper (1) thereby reliably prevents penetration of foamed oil into a working chamber (A, B) thus effectively preventing loss of functionality as a result of the low viscosity of the oil foam. The high performance vibration damper (1) is also characterized by a very compact and simple construction.

Title: Motor vehicle body pillar cover design
Inventor: MIYANO ATSUSHI
IPC: B60R13/02
Filed: 1998-10-29
Abstract: The rib pairs (3a,b) are spaced out along the inside of the C-shaped main body (2) so as to stand vertical from one sidewall (2a,b) to the other so the free ends of the ribs stand free. The ribs per pair from the two sidewalls register with one another leaving a clearance of (d), being 1/5 to 4/5th of the distance between the top edges of the sidewalls (2a,2b). Otherwise the ribs run out from the opposing sidewalls in a staggered array so each is spaced from the opposing sidewalls leaving clearance (d) equal to 2/5 to 4/5th of the interval between the top edges of the sidewalls.   In a variant, each rib is recessed similar to the interior of the main body (2), and the ribs are beveled off in each case where they meet the sidewalls.
Patent DE-19853049-A1 (DE)
Title: Leak testing of engineering components comprises use of high pressure test gas, carrier gas, discharge tube detector and laser spectrometer, where both gases are constituents of air
Inventor: HAAS ULRICH
IPC: G01M3/38
Filed: 1998-11-17
Abstract: The objects are located within a flow of a carrier gas and a small amount of a test-gas is internally introduced to the object; alternatively the relative locations of the two gas systems may be reversed. The test-gas is at higher pressure than the carrier gas, into which it will flow if a leakage path exists. The outlet gas from the device is examined for the presence of test-gas by feeding it into an electrical-discharge cell to produce a plasma and analyzing the radiation from the excited gas by laser-absorption or laser-fluorescence spectroscopy.  A test object (1) is connected between three-way valves (7,9) , which are set such that carrier gas first flows from a source (3) , via a valve (5), direct to a discharge cell (20) under the influence of a first vacuum pump (14), capable of drawing vacuum down to levels of 1-10 mbar abs.. Simultaneously the test object is evacuated via a valve (9) and a second vacuum pump (15). On reaching a predetermined vacuum level (e.g. 2 mbar), as detected by a gauge/pressure switch (13), the valves are swung to allow the carrier gas to flow through the test object and into the discharge cell. The test object is surrounded by or swept by a jet of test-gas.

Patent DE-19912754-A1 (DE)
Inventor: STRUDEL WERNER
IPC: D06C5/00
Filed: 1999-03-22
Abstract: Tubular knitted fabric, with an elastomer and natural fiber content, is relaxed while spread out into a tube. It is heated below the softening temp. of the elastomer and moved through at an initial speed. It is then fixed longitudinally and laterally at a different speed at a temp. which softens the elastomer fibers. The fabric is cooled at a temp. below the softening point of the elastomer. The speed of fabric movement during fixing is faster than the first speed. The fabric is fixed with simultaneous stretching of the material across the dia. and along its length within a thermal fixing chamber using a circular spreader. The fabric is drawn out of the chamber at the second speed level by a rotating roller assembly. The relaxation temp. is 80-110 degrees C. The thermal fixing temperature is ≥ 200 degrees C while the material is moved at a speed of ≥ 18 m/min. The fixing temp. is ≤ 200 degrees C at a fabric movement speed of ≤ 18 m/min. The heat is delivered by a high temperature medium, and the cooling is through a low temperature medium. The heating during relaxation is preferably through high temperature steam. The fabric, held out by a circular spreader, is at least affected for its length during the relaxation phase. The circular spreader is within the relaxation and/or thermal fixing chamber. The fabric length is affected by rotating roller assemblies upstream and downstream of the circular spreader. The speeds of the roller assemblies are set independently of each other. An Independent claim is included for an assembly with a relaxation chamber (7) fitted with an inlet (6) and outlet (13) opening, and a heater (12). The circular spreader (9) in the relaxation chamber (7) is flanked by upstream and downstream rotating roller units (5,15). A thermal fixing chamber (18), separated from the relaxation chamber (7), has an inlet (21) and outlet (22) opening and has a circular spreader (19) occupying most of it, flanked by upstream and downstream rotating roller assemblies (16,35). A heating unit (24) generates a high temp. medium, to be blown into the chamber (18) by a fan (28). A cooling chamber is after the outlet opening (22), with the circular spreader (19) extending at least partially into the cooling chamber.

Title: Müllfahrzeug in Systembauweise
Inventor: SCHILLER ROLF
IPC: B65F3/00
Filed: 1999-04-15
Abstract: Die getrennte Hausmüllsammlung erfordert zur Kostenminimierung den Einsatz von Fahrzeugen mit zumindest zwei Stauräumen für die gleichzeitige Sammlung verschiedener Müllfraktionen. Fener kommt dem Auswechseln der Stauräume ("Containerisierung der Müllfahrzeuge") steigende Bedeutung zu. Zur optimalen Anpassung an die lokalen Verhältnisse wird vorgeschlagen, Aufbauten zu verwenden, bei denen die Stauräume auf einem Gestell zumindest teilweise unabhängig voneinander am Fahrzeug auswechselbar sind oder aber neben einem am Chassis oder einer Wechselbrücke befestigten Stauraum zumindest einen weiteren auswechselbaren Stauraum besitzen. Hierdurch wird das Auswechseln von Stauräumen erleichtert und kann auch die Konstruktion vereinfachen. Es ergeben sich weitere Vorteile für die Planung der Sammeltouren, ferner durch die Festlegung von Stauraumvolumina, die nicht den erwarteten Volumina der Müllfraktionen entsprechen.
