Patent DE-19516275-A1 (DE)
Title: Moisture measurement using optical fibre having quartz glass core
Inventor: EBERL RONALD DR
IPC: G01N21/3554
Filed: 1995-05-08
Abstract: The moisture measurement involves one or more light wave guides each with a quartz glass core surrounded by water-permeable claddings, a light source directing light into the guide an a detection device for measuring the intensity of the transmitted light in determined wavelength ranges. Changes in the evanescent absorption in the wavelength of the near infra red water absorption bands indicate the presence of water at the fibre optic core, from which the surrounding moisture can be evaluated. The transmitted wavelength should be between 1.8 and 2.1 micrometres and/or 1.3 and 1.6 micrometres. The fibre optic wave guides are installed close to each another at measurement location, and are connected to the measuring device only during the measuring process.

Patent DE-19519370-A1 (DE)
Inventor: BROECK HEINZ VAN DER DR
IPC: H02J1/12
Filed: 1995-05-26
Abstract: The circuit provides 3 AC voltages (U1,U2,U3) of equal frequency to respective terminals connected to the outer ends of each motor winding (17,18) and to a common node coupled to the inner ends of each winding. The voltage (U2) supplied to the common node terminal has a rectangular voltage waveform and is offset in phase from the sinusoidal voltages (U1,U3) supplied to the other 2 terminals, so that the resulting winding voltages (UA,UB) are offset in correspondence to the mechanical offset between the windings. Each of the sinusoidal voltages has constant amplitude sections and pulse modulated sections, with the constant sections of one voltage coinciding with the modulated sections of the other.
Patent DE-19520819-A1 (DE)
Inventor: HILLMER HARTMUT
IPC: H01S5/12
Filed: 1995-05-30
Abstract: The method uses plate or disk type materials in making optoelectronic components with gratings of variable grating periods using common structuring processes. A number of optoelectronic components are simultaneously manufactured next to each other on the surface of the material. Each manufacturing step involves making the same changes to all components using a lithography mask for the individual manufacturing steps. Each mask has a planar geometric pattern. For each mask, all possible variations of individual component patterns are derived from the geometric pattern by mathematical rotation about 180 degrees about an axis perpendicular to the mask surface and by reflection about an axis parallel to the limits of the individual component. The electric and optical properties of the resulting component are nominally identical. A unitary cell is formed from the variations of the pattern by shifting the variations in the x and y directions. The unitary cells are added together such that the rigidity and difference capability of the overall mathematical waveform function is guaranteed. The incident angle of the waveguide at the left edge of the unitary cell matches the outlet angle of the waveguide at the right edge. The unitary cells are reproduced until the active surface of the mask is completely covered. The active surface of the mask extends beyond the material in all directions. The above steps are used successively for the design of all other masks to produce a geometrically consistent lithographic component manufacture.

Title: Controlling melting and fine-casting process
Inventor: SCHMID STEPHAN
IPC: B22D46/00
Filed: 1995-11-10
Abstract: The melting and casting process consists of three phases, and utilises induction heating. At the first phase, under vacuum, the maximum power is applied to the material until its complete melting. The power supply is then interrupted for up to one minute. At the second phase a reduced power is supplied to the melt over a specified period, with constant regulation of the supply on the basis of a predetermined target value. The period length and the power supplied are adjustable dependent on the alloy type. At the third phase casting takes place under pressure, with reduced power supply continued up to the end of the process. Also claimed is a casting unit for the above process.

Title: Circuit for indirect measurement of alternating current and voltage of electrolyte of object under test
Inventor: RIESE BURKHARD DIPL ING
IPC: G01R27/22
Filed: 1996-04-27
Abstract: A device for indirect measurement of alternating currents and voltages, particularly for use in the inductive measuring of electrolytic conductivity, comprises a switching circuit with a measuring cell (1), a transmission coil (2) and a receiving coil (3). The signal input (E) is adjustable to a null voltage. A phase-sensitive alternating current indicator (AS1) produces a synchronised signal with the deviating signal from the input and is linked to a control amplifier (V1), the output from which is return-coupled by a phase-sensitive compensation arm (7) to the input. The output signal (UA) from the amplifier, after passing through an analog switch (AS2), corresponds to the measuring alternating signal (ie). The system requires minimal use of amplification and very low power consumption of only 10 mW. It is highly accurate.
Patent DE-19617961-A1 (DE)
Inventor: AGUEEV VLADIMIR DR
IPC: G01P13/02
Filed: 1996-05-06
Abstract: The invention relates to a method of measuring the rate of flow of gaseous or liquid media using ultrasound, and a measuring device suitable for carrying out said process. Known ultrasound measuring devices use pairs of acoustic transmitters and receivers facing each other. The wind-controlled sound velocity in the measured sections is determined by the measurement of operation times or by the measurement of phase displacements in relation to the output signal. Sound velocity is no longer controlled by physical conditions of the wind due to the fact that measurement occurs in alternate directions for which high-grade transmitters/receivers are required. According to the present invention in addition to measurement in at least one measured section the operation time of a signal is determined within a reference section which is connected to the medium and in which there is no flow, but otherwise the conditions are the same as in the medium, and the rate of flow of the medium in each signal direction is derived from the difference of the reciprocal values of the operation times of each measured section and the reference section. The method is suitable for all flow measurements in gaseous or liquid media.

Filed: 1996-06-21
Abstract: The method involves a linear optical system which produces a flat beam (3) projected on a to plane at right angles to the direction of the flat beam in the form of a straight line image.
