Title: Process for producing an interior lining for motor vehicles
Inventor: PELZER HELMUT
IPC: B29C49/00
Filed: 1988-02-22
Abstract: Conventional relevant processes are complex and expensive. The products of the process are difficult to manipulate and have inadequate sound-insulating and heat-insulating properties. The novel process is intended to be simple and uncomplicated, less time-consuming and inexpensive and also to result in good heat-insulating and sound-insulating values of the product. The process is carried out using a thermoplastic tubular film by drawing a cut-to-length section of the tubular film flat in its width in such a way as to produce two film sheets running parallel to each other a few millimetres apart and joined on the longitudinal sides. These are placed in a thermoforming mould, after which a honeycomb pattern is impressed into the one film sheet, while the other remains smooth. The two film sheets are laid one on top of the other and joined by heating. At the same time, they are jointly brought into their intended final form. When carrying out the novel process, the moulded part is produced virtually in one operation.

Title: Constant-temperature anemometer
Inventor: HOFFER OTTO DIPL ING
IPC: G01R17/10
Filed: 1988-03-02
Abstract: Bridge circuit for operating a temperature-dependent electrical resistance as a velocimeter and flow meter (flow-rate meter, rate meter) in flowing media, characterised in that an N-channel enhancement MOSFET is used to control the bridge current and transmitter current. In order to produce the control voltage (gate voltage) of the MOSFET, a difference is formed between the voltage at the transmitter and the voltage at the standard (reference) resistance, which is used as the input voltage for a controller, which is to be an I controller, PI controller or PID controller. The output voltage of the controller is then the gate voltage being sought. Since the transmitter temperature is held constant, the electric voltage supplied in order to keep the transmitter temperature constant is a measure of the flow velocity and of the rate of flow.

Title: Process for the removal and disposal for the purposes of recycling or other use of spray material mist from the exhaust air and of spray material residues in toto in processes for the spray coating of articles with organochemical coatings
Inventor: SCHLEFFLER GERHARD DR
IPC: C09D7/00
Filed: 1989-02-15
Abstract: In the spray coating of articles, spray material mist from the exhaust air and other material residues have hitherto been precipitated in a manner causing denaturing and disposed of by destruction or landfilling. For the purposes of recycling or alternative use of such overspray, etc., spray booths in the novel process are operated - instead of with chemicals-containing water as in the prior art - with liquid, low-viscosity polyols or PVC plasticisers as wash liquids. Solvents - originating from the coating material - and acid components in the resultant mixtures (I) of coating composition residues with such wash liquids are removed or deactivated, and the mixtures (I) treated in this way are used for condensation resins or polyurethane compositions in the case of polyols and for flexible PVC compositions in the case of PVC plasticisers, or coatings in both cases. Instead of inconvenient, environmentally polluting disposal, recycling saving raw materials becomes possible.
Patent DE-3908653-A1 (DE)
Title: Process for improving the fatigue strength of welded high-strength steels
Inventor: MUESGEN BRUNO DIPL ING DR
IPC: C21D9/50
Filed: 1989-03-16
Abstract: Components or workpieces of welded, high-strength (high-tensile) steels (tensile strength greater than 500 N/mm<2>), which are subject to vibrational stress, have the drawback that the fatigue strength in the region of the weld (welded seam) is considerably lower than the fatigue strength of the base material. This applies even to those high-strength steels in which the weld interfaces (plate-weld junctures, weld-base metal interfaces) have been after-treated by means of the known tungsten-inert gas method. According to the invention, after-treatment of the welds can be effected by means of local energy supply, preferably by inert gas arc welding by means of a tungsten electrode, in such a way that the workpiece is preheated at least to the saturation preheating temperature, which depends on the steel grade, and then the weld zone is after-treated with a specific stretching energy (kJ/cm). This ensures that the weld and the base material achieve a matching permanent fatigue strength. In Figure 4, the overall area bordered by the reference symbols 1 to 7 shows the usable regions of current intensity, stretching energy and feed rate of the electrode. For those welded workpieces or components which are used in the offshore sector and thus are subject to vibrational stress not only in the air but also in sea water, there is the additional hazard of stress corrosion cracking (SCC), which can be avoided by the preheating to the hardness-limiting temperature </= saturation preheating temperature. <IMAGE>
