Patent DE-3828128-A1 (DE)
Inventor: TELLERT RUDY
IPC: G01M13/02
Filed: 1988-08-18
Abstract: The momentary friction performance of a motor vehicle clutch is ascertained in a computer (25) in dependence upon the torque to be transmitted by the clutch (3) and the slip of the clutch. In several stores (37, 41, 45) mean friction performance values are accumulated which are corrected in time dependence but with different rate of variation by correction devices (39, 43, 47), in accordance with the temperature behaviour of the clutch (3) on the surfaces of the friction linings (15), the mean temperature behaviour of the fly-wheel (19) and of the presser plate (23) and the heat emission to the surroundings. Monitor devices (49, 51, 53) allocated to the stores (37, 41, 45) ensure the monitoring of these temperature conditions in dependence upon specifically pre-determined limit values. The arrangement thus permits a more exact and more rapidly responding temperature monitoring of the friction clutch. <IMAGE>

Title: Method and device for measuring the gas concentration of a liquid plastic component
Inventor: WEBER WERNER DR
IPC: G01N33/44
Filed: 1988-09-06
Abstract: For measuring the gas concentration of a liquid plastic component for the production of polyurethane foam materials, a sample is extracted from the main quantity of the plastic component and led into a piston-cylinder unit (4). The sample pressure is subsequently measured and the volume of the probe is changed from a first volume to a larger second volume. For this purpose, the piston (8) of the piston-cylinder unit is moved hydraulically from a first position into a second position. During and/or after the expansion of the sample, it is exposed to a shear field of 0.5 to 1000 sec<-1> with the aid of a stirring element (12) projecting into the cylinder (5). By means of the shearing of the sample, the desorption of the gas dissolved in the component is started or accelerated, so that the subsequent pressure measurement also takes into account the proportion of gas dissolved in the component. From the difference value of the pressure measurement, the actual gas concentration of the component may be determined. <IMAGE>

Title: Process and apparatus for purifying waters of oxidisable carbon compounds contained therein
Inventor: SCHENCK GUENTHER O PROF DR

Filed: 1988-10-28
Abstract: The apparatus has two purification stages (I, II) connected in series each having a circulation (2, 22) having a throughflow photoreactor (1, 21). Each throughflow photoreactor (1, 21) is differently dimensioned at least with respect to the total optical path length according to the initial transmission and the transmission change effected therein.

A feed pump (10, 13) for an oxidising agent forming oxygen free radicals under UV radiation at least in the first purification stage is controlled according to the initial transmission of the particular throughflow photoreactor. <IMAGE>

Patent DE-3843937-A1 (DE)
Inventor: MERZ ALBERT DR
IPC: B09B3/00
Filed: 1988-12-24
Abstract: In a process for recycling organic pollutants contained in the fly ash from an incinerator into the latter for the destruction of dioxins and furans in filter cakes formed, for example, by solid/liquid separation from fly ash combined with scrubbing fluid, as residues from a waste incinerator, the pollutants are embedded before the recycle into a ceramic matrix which remains essentially stable dimensionally even under the mechanical stress in the incincerator until after the temperature action due to the combustion of the slag. For this purpose, the filter cakes are adjusted to a defined residual moisture content, subsequently mixed with a defined fraction of bentonite, heated and then recycled at a defined geometry into the incinerator furnace.

Title: Colour changer for an illumination device
Inventor: VOEGELI WERNER
IPC: F21V9/08
Filed: 1989-03-13
Abstract: A compact arrangement, which is inexpensive to produce, for a colour changer of an illumination device contains in concentric arrangement around a light source (2) three dichroically vapour-coated glass tubes (4, 6, 8), of which in each case one tube filters one colour component (blue, green, red) out of the white light emitted by the light source (2). The tubes (4, 6, 8) can be adjusted parallel to their longitudinal axis by means of a suitable adjusting mechanism (10-20) in such a manner that they are totally, partially or not at all in the beam path of the light source (2). Chromatic aberrations are virtually ruled out since the main component of the light beams emitted by the light source (2) impinges perpendicularly onto the surface of the dichroic filter tubes (4, 6, 8). <IMAGE>

Abstract: A consolidated, reinforced composite member is made from a matrix mixture including a consolidation shrinkable discontinuous material, for example ceramic particles, and a particulate inorganic filler which will exhibit net expansion relative to the discontinuous material, the mixture being interspersed about reinforcing fibers to provide a preform. Subsequent consolidation of the preform can be conducted at ambient pressure, without application of additional pressure. The member may be an airfoil shaped strut (10), useful in a gas turbine engine hot section, which is made by disposition of plies 22 formed from the matrix mixture and fibres, e.g. fabric, about forming blocks 24, e.g. of aluminium, the assembly being placed within forming dies (26A, 26B) and pressure being applied while the assembly is heated. The resulting preform is sintered in a furnace to a consolidation temperature, without external pressure being applied. The ceramic particles are preferably alumina and the filler may be pyrophillite. <IMAGE>
