Title: Method and device for the ultrasonic material testing of workpieces
Inventor: SCHLAWNE FRIEDHELM DR
IPC: G01N29/28
Filed: 1988-04-25
Abstract: The invention relates to a method for the acoustic coupling of a specimen in ultrasonic material testing of workpieces with an ultrasonic test head, in which the transmission of the emitted sound onto the specimen is achieved by means of a magnetic liquid arranged between the specimen and the test head, the said liquid being held by a magnetic field acting on it and having the emitted sound running through it. In order to provide a method which, under exactly defined coupling conditions and in a long-lasting testing cycle, allows a safe and reliable as well as reproducible test in the case of ferromagnetic and non-ferromagnetic and electrically non-conducting specimens, and to provide a device which is simple to produce and easy to manage, it is proposed that a strongly inhomogeneously pronounced magnetic field is generated, whose field gradient reaches its largest value in the region of the introduced quantity of the magnetic liquid between the test head and the specimen surface, the bundle of sound waves is led through the magnetic liquid inside the propagation surface which is adjusted by means of the magnetic field and the magnetic liquid which is gradually consumed during a long-lasting test cycle is continuously replaced. <IMAGE>

Patent DE-3840819-A1 (DE)
Inventor: HAUFE PAUL J M
IPC: F02M37/00
Filed: 1988-12-03
Abstract: To remove combustible suspended particles, in particular soot, from the combustion gases of liquid fossil fuels, the soot is washed into the liquid fossil fuel itself and thus recycled to the combustion process. A separator for carrying out the process comprises a plurality of baffle plates coated in a certain region with a thin film of fuel onto which the combustion gases are directed. The suspended particles are deposited onto the baffle plates in this region. The baffle plates are moved continuously in such a way that their charged surface regions are moved into a supply of the liquid fuel where the adhering suspended particles are dispersed into the liquid fuel.

Patent DE-3937466-A1 (DE)
Inventor: NOSKE HEIKO DIPL ING
IPC: B23B31/177
Filed: 1989-11-10
Abstract: In machine tools, in particular turning machines, the workpiece being machined is held in a holder. To ensure safe operation, a certain minimum gripping force must be maintained. If this force is too small, the workpiece can be thrown out of its holder, which represents a considerable accident hazard. It should also be noted that the workpiece-gripping force decreases as the friction surfaces of the chuck become progressively less well lubricated and progressively dirtier. The invention therefore proposes that the chuck jaws act to produce a gripping force, the hydraulic energy producing this force is monitored and, when a given energy threshold is exceeded, a signal is triggered.
Patent DE-3937723-A1 (DE)
Inventor: SIGMUND HERMANN DR ING
IPC: H01L21/316
Filed: 1989-11-13
Abstract: Described is a process for producing a silicate layer, in particular an intermediate-oxide insulation layer used to equalize surface irregularities in an integrated circuit, by means of the following steps: Polysiloxane is first produced by photo-inductive polymerization in the gas phase, beginning with an SiO-containing or SiC-containing organic compound plus an O2-containing and/or N2O-containing gas at a first temperature and a first pressure in a reaction chamber; the polysiloxane is condensed to give a polysiloxane layer on a surface structure, in particular the circuit structure of an integrated circuit, in a condensation chamber separate from the reaction chamber and at a second temperature lower than the first, the second temperature being high enough for the SiO-containing or SiC-containing organic compound not to condense at a given second pressure in the condensation chamber but higher than the temperature at which the polysiloxane condenses at the second pressure; the polysiloxane layer is then converted into a silicate layer.
