Patent DE-19816325-A1 (DE)
Title: Treating inner surfaces of hollow workpieces consisting of aluminum or aluminum alloys
IPC: C23C18/32
Filed: 1998-04-11
Abstract: A workpiece (28) is connected to a piping system to produce a forced flow of solutions through the workpiece. The hollow workpiece is connected to a piping system so that it is subjected to a forced flow of various solutions without any substantial loss of heat energy or chemicals. Solutions necessary for individual treatment steps are delivered from different storage tanks. After each treatment step the piping system cleaned from the chemical residues by blowing with compressed air and rinsing with demineralized water.  The storage tanks (1-5, 30) of are joined to one another and to the workpiece (28) undergoing treatment by means of the delivery and return piping (6, 7). Required pressures and throughput are ensured by means of a pump (29). The line (8) serves for delivery of compressed air which subsequently (after cleaning) is removed through an exhaust system (9).

Title: Generating discharges between two or more electrodes for e.g. a gas laser
Inventor: USEDOM PETER
IPC: H05B41/28
Filed: 1998-04-11
Abstract: This device has two electrodes (4,5), of which one is coated with an insulating layer (6,7) such as a dielectric.

Title: Readily assembled unitary safety valve used in e.g. an engine oil filter cartridge
Inventor: SUZUKI YASUYOSHI
IPC: B01D27/10
Filed: 1998-04-23
Abstract: A safety valve (40) closes and opens a fluid passage (35), in a wall of a cylindrical fastening section (33), as a function of pressure difference between the inside and outside of the fastening (33).

IPC: B65H37/00
Filed: 1998-12-22
Abstract: A device for transferring a material in the form of a film that is applied to a carrier strip onto a substrate such as a sheet of writing paper or drawing paper. The inventive device comprises a housing that accommodates a supply reel for the film-coated carrier strip and an empty reel that receives the carrier strip when the coating is removed. The film-coated carrier strip is guided via an application foot that is provided with at least one clip-type sliding element which is made of a friction-reducing material in the area around which the carrier strip is twisted and secured to said foot. The aim of the invention is to prove an improved device that uses as little material as possible, whereby close attention is paid to aspects such as low production costs and easy assembly, while at the same time guaranteeing smooth operation and flawless transfer of the film onto the substrate. This is achieved by providing the application foot (6) with a pivotally hinged extension arm (9) with a terminal receiving profiled section (end section (10)) for the sliding element (15).

Patent DE-19902795-A1 (DE)
Inventor: OECHSNER RICHARD
IPC: G05B19/418
Filed: 1999-01-25
Abstract: The invention relates to a method for surveying the quality of a number of technical product types (P, P', P") which are produced in a quasi-parallel production process. The aim of the invention is to represent a number of process data obtained from the process with as much of an overview as possible rather than surveying each individual parameter to be controlled with its own representation. To this end, the quasi-parallel production of various product types is surveyed by calculating an average from measured values of a technical product parameter from a sample of a first product type in a production station (S1) and storing this average in a multidimensional averages vector in the form of a scalar. At the end of a fixed interval of time (T1), the multidimensional average is converted into a state value (T<2>) for the production of several product types in the production station. Several averages from the production process can influence individual scalars of the multidimensional average during the fixed interval of time. The state variable can be calculated using a T<2> Hotelling statistic.

Title: Apparatus quantifying quality of structured surfaces, employs diverse strategies in transmitting light from source to receiver, to detect and quantify influences including shape, color, reflectance and topology
Inventor: SCHWARZ PETER
IPC: G01N21/88
Filed: 1999-03-04
Abstract: First and second optical units are so constituted that reflected light is influenced by the surface measured. A unit evaluates the reflected light, from which a structure-moderated property of the surface is characterized. (Note that the word reflected here will not generally imply specular reflection)  Preferred features: Light from the first unit is patterned, including light and dark edge(s), running parallel. The light is in a raster, orthogonal grid or circular pattern. A fraction of the total illumination has no pattern. Differences between and gradients from sensor outputs, establish increases in measured signals corresponding with the pattern. From a cross section of the gradients, a structure-dependent characteristic of the surface is determined. The method is further detailed, salient features being summarized in the following. Reflectivity, sheen, and contrast are taken as characteristic. Surface topology (e.g. orange peel effect) is established optionally in two or more wavelengths. The angle(s) of measurement are variable, a stepped progression being suggested. Fresnel reflection is employed. Various forms of optical beam or cone are described. Temperature correction (optical) is included.

Inventor: KUEPER PAUL
IPC: F01N11/00
Filed: 1999-03-09
Abstract: The invention relates to a method for monitoring the function of catalysts in internal combustion engines according to which similar operational states (bz) are determined on the basis of operational parameters of the internal combustion engine already detected. According to the inventive method, a statistically proven average exhaust gas value (agmw) is calculated on the basis of a defined number of measured exhaust gas values (agw) during a similar operational state. Said average value is compared with a permissible exhaust gas value that is stored for said operational state. If the detected exhaust gas value deviates from the permissible exhaust gas value (agwsp), a dysfunction of the catalyst is recognized.
