Patent DE-19755725-A1 (DE)
IPC: B29C45/16
Filed: 1997-12-15
Abstract: Rotatable rolls of plastic material are produced in the following manner: a thermoplastic material is injected between a roll shaft and an outer roller layer, whereby the volume of said material contracts during cooling, shrinks onto the roll shaft and shrinks away from the outer roller layer, or the outer layer is initially injected according to a multi-component injection moulding method, after which a thermoplastic material is injected between the outer roller layer and the roll shaft, whereby said material also shrinks onto the roll shaft and shrinks away from the outer roller layer. Said method produces rolls of plastic material, consisting of both an inner roller layer (2) which is firmly connected to the roll shaft (1) and an outer roller layer (3) which can rotate freely against said inner layer by means of a sliding gap.

Title: Method for leakage testing of side or secondary ducts
Inventor: JOECKEL ULRICH
IPC: G01M3/04
Filed: 1998-01-10
Abstract: The method involves using a truck (8), which seals a main duct (2) before and behind a secondary duct (3). A satellite camera (15) is introduced in the secondary duct, in the test chamber (17) created between the seals, and a first leakage test is carried using a gaseous medium. If the first test fails, the pressure chamber (17) is filled with a fluid medium (25), to perform a second test. This action removes the seal in the secondary duct.

Title: Vehicle headlamp
Inventor: FADEL KAMISLAV
IPC: F21V7/00
Filed: 1998-02-07
Abstract: The headlamp has a bulb, a mirror and a lens. The mirror contains a number of zones of smooth reflecting surfaces which are located beside each other and are bounded by transition lines with discontinuities in slope. Each of these zones can scatter the light horizontally between two extreme values which result in the direct neighbourhood of the transition lines. The extreme value of the horizontal scattering of each zone changes progressively by the measure in which one moves along the transition line concerned. The reflecting surfaces of at least some of the zones lie  on a non-parabolic horizontal generatrix.

Patent DE-19811989-A1 (DE)
Inventor: MUELLER JOERG
IPC: G02B6/124
Filed: 1998-03-19
Abstract: The invention relates to a spectrometer, comprising a thin light guide layer in a layered structure produced using thin-film technology between two cover layers having a lower refractive index, a light guide layer end face which has a grid and is irradiated through the light guide layer with light to be analysed, and a line-scanning sensor on which the spectrum is displayed. The stair-like stepped grid is configured as having transparent step surfaces and step edges perpendicular to the layer plane and a second medium is adjacent to the step surfaces of the grid whose refractive index is smaller than that of the light guide layer. The invention is characterized in that the grid continuously changes the height and width of its steps in the direction of the stairs in such a way that for two selected wavelengths the total light paths travelling through the light guide layer and the second medium as far as a focal point assigned to the corresponding wavelength for all adjoining front surfaces of the grid have a difference in length which is equal to the same multiple of said wavelength.
Patent DE-19818893-A1 (DE)
Inventor: LECHNER MARTIN
IPC: F01L1/24
Filed: 1998-04-28
Abstract: The invention relates to a hydraulic valve-play compensation element. The aim is to prevent any change in the length from taking place when the engine is at a standstill. To this end, the leakage oil is guided into the space between the high pressure valve (4) and the valve (5), where it then reinforces the sealing effect of said valve (5). When the engine is in operation, the valve (4) is kept open irrespective of the direction of throughflow by means for producing a defined force, for example a pressure-loaded piston or by electromagnetic means.
Patent DE-19819750-A1 (DE)
Inventor: ZIEGLER MAIK
IPC: B32B5/18
Filed: 1998-05-02
Abstract: The invention relates to a composite material comprised of a particle foam made from expanded polypropylene (EPP), of at least one fibrous layer, and of at least one layer made of a polymer which is applied on said fibrous layer. An intimate composite is assured due to the fact that the fibrous layer is a mixed fibrous layer having a proportion of fibers made of polypropylene (PP) which are heat welded with the EPP particles. En addition, the fibrous layer comprises another proportion of reinforcing fibers which exhibit a sufficient wettability for the polymer which is solidified, hardened or cross-linked from the liquid phase and which is applied on the free surface of the fibrous layer. The invention also relates to a method for producing said composite material.

Inventor: AUE VOLKER
IPC: H04B1/707
Filed: 1998-10-05
Abstract: The invention relates to a method for receiving spread-spectrum signals for fine time synchronization of correlators in a RAKE receiver. The objective of the invention is to produce a signal that is to be transmitted with the highest possible signal to noise ratio on the basis of the received signal. To achieve this, a higher level unit intervenes in the normal adjustment of a first basic time lag in a first RAKE finger and the normal adjustment of a second basic time lag in a second RAKE finger when the difference between the basic time lags of both RAKE fingers corresponds to a minimum level, and subsequently carries out a joint adjustment for both RAKE fingers, taking time error estimates for both RAKE fingers into account.

Title: Detektorschaltung
Inventor: REGENSBURGER MARTIN
IPC: F42C13/02
Filed: 1998-12-22
Abstract: Die Detektorschaltung (11) eines strahlungsempfindlichen Sensors (10) mit kapazitiver Hochpaß-Kopplung (14) zwischen Vorverstärker (13) und Signalverstärker (15) wird wegen der großen Filter-Zeitkonstante des Längs-Kondensators (25) auch noch nach Beendigung einer Übererregung für längere Zeit (T2) blockiert, weil der Kondensator (25) nur langsam umgeladen wird und deshalb der ihm folgende Signalverstärker (15) zunächst noch übersteuert bleibt, bis der Kondensator (25) wieder auf einen Gleichspannungspegel im Aussteuerbereich (39) des Signalverstärkers (15) umgeladen ist. Diese Totzeitspanne (T2) wird jedoch auf einen kleien Bruchteil (T1) verkürzt, wenn mit Beendigung der eingangsseitigen Übererregung der Kondensator (25) ausgangsseitig, als vor dem Signalverstärker (15) zum Potentialabbau über eine niederohmige Schaltstrecke (31) zwangsweise auf das - virtuelle - Massepotential am Verstärkereingang zurückgeführt wird. Solche Umladung kann außerdem softwaregesteuert ausgelöst werden, wenn über eine längere Zeitspanne hinweg keine verwertbaren Nutzsignale (17) aufgetreten sind, weil beispielsweise eine permanent hohe Aussteuerung des Sensors (10) zu einer zu starken Potentialverschiebung am Koppelkondensator (25) geführt hat.

Title: Optionally-electrostatic, sub-micron particle filtration system treating gases for analysis in chamber by calibrated sensors, includes fully-automatic gas-flushing equipment for filter, preventing sensor contamination
Inventor: SEELIGER HANS-DIETER
IPC: G01N33/00
Filed: 1999-01-11
Abstract: The filtration system comprises fully-automatic gas-flushing equipment, for continuous or intermittent cleaning.  Preferred Features: The filter (1) is blasted by pressurized medium. With the fan shut off, a measured quantity of pre-pressurized medium in a cylinder (10) is delivered via a flushing line into the filter, to leave with the finest particles, via an outlet. In cyclic operation, the sample flow is interrupted by shutting off the fan, followed by injection of the medium. Inlet and outlet valves (8,11) open and close appropriately, ultimately restoring sample flow to the sensor chamber (2) and sensor (21). Timing is adjustable, or is controlled automatically in terms of total throughputs.
