Patent DE-4117367-A1 (DE)
Title: Modifying magnetic field in sputter equipment with rotating target - results in a box-shaped profile of material removal on the target surface which improves the efficiency and reduced penetration danger
Inventor: HARTIG KLAUS DR
IPC: C23C14/34
Filed: 1991-05-28
Abstract: A homogeneous removal profile of target material from a cylindrical target surface in sputter equipment using a magnetron is obtd.. The feature is that the magnetic field, which concentrates and shapes the plasma, is modified, esp. in its geometry, so that the erosion region on the rotating target has a rectangular profile with steep edges of the trench. The racing track shape trough, with long and short elements, formed by the erosion of the target is pref. changed into a square with equal length elements. The change of the magnetic field can be achieved by changing the position of at least 1 magnet, by change of the strength of at least 1 magnet, by a change in the number of magnets used, by using an electromagnetic to influence, aid or oppose the field of the permanent magent. Also claimed is the change of the magnetic field by changing the distance between magnet poles, the distance between 2 magnets; the distance between at least 1 magnet and the target surface, the angle of at least one magnet with the rotating target, the shape of at least one magnet pole, the use of a shunt on at least 1 magnet or the use of a special pole shoe. USE/ADVANTAGE - The process change allows a higher efficiency of target use by eroding the outer layer at a constant rate. This reduces the danger of penetrating the outer layer, which in extreme cases could lead to escape of coolant water into the vacuum chamber.

Title: Reconditioning metallurgical residues with reduced installation costs - involves agglomeration or pelleting of residues, supplying to counted-flow melting unit with dust filter, heating and drying, etc.
Inventor: SINDELAR GUENTER DR ING
IPC: C22B7/02
Filed: 1991-07-17
Abstract: The method for metallugical reconditioning of metallurgical residues (filter dust and sludge, scale, grinding dust etc.) involves their agglomeration or pelleting (with or without additives), supply of agglomerate to a counter-flow melting unit with dust filter, and preliminary heating and drying of the agglomerate in the upper charge region of the unit. This is followed by sintering and reduction of the agglomerate in the reduction region of this unit, with subsequent liquefication of the reduced agglomerate, and final tapping (continuous or discontinuous) of the resulting metal and slag phase. Pref. the dust from the filter of the melting unit is agglomerated anew and subjected to the same processes as the original residues to enrich metals with a low b.pt. e.g. Zn and Cd. The enriched filter dust, dependent on its compsn. is subjected to a special nonferrous metal reconditioning process. A powdered or fine granular carbon carrier is used as a reduction agent in the melting unit. USE/ADVANTAGE - The method can be used in metallurgical plants. In comparision with known methods (which require four large separate units respectively for pelleting, roasting, reduction and melting), it allows the installation costs to be substantially reduced.

Title: Laser optical sensor measuring method for determining refractive indices - introducing varying refractive index medium to cause frequency shift or modulation of solid state laser
Inventor: MEHNERT AXEL
IPC: G01N21/41
Filed: 1991-08-01
Abstract: The refractive indices measuring method involves varying the optical wavelength of a diode-pumped solid state laser resonator by introducing a medium with varying refractive index. The refractive index variation is measured as a direct frequency modulation of the sensor laser. The laser signal is frequency shifted or modulated in proportion to the deflection of a sensor, and coherently optically superimposed with a reference laser signal. The difference between their frequencies or modulations is proportional to the refractive index change. The reference laser is housed in the same medium as the sensor laser so that they both experience some temp. effects. USE/ADVANTAGE - For measuring refractive indices of gases or liquids, e.g. for measuring conc. of mixtures. Compact measurement arrangement.

Title: Warp knitting machine - has hooked needle and thread guides reciprocating in same direction during lap
Inventor: KRESS EDGAR
IPC: D04B23/02
Filed: 1991-09-06
Abstract: A warp knitting machine utilises crochet needles in a needlebar working with at least one thread guide bar. The needle bar has a reciprocal motion, while the guide bar has a shogging motion to lap the needles. Additionally, there is a reciprocal motion of the guide bar in the same direction as the needle bar. Pref. mainshaft drives the eccentrics attached to connecting rods. The arm swivels on a centre to provide reciprocation of the hooked needles set in a bar. As this rises and falls, so does the thread guide bar with the guides, meeting the hook needles along part of the trajectory, and accompanying the working part as it rises and falls, and at the same time overlapping and underlapping, to form the loops of the knit. This movement is provided by the connecting rod giving a rise and fall movement at the appropriate time, and partly by connecting rod, which moves the guide bar back and forward by the mechanism, through the needles when the guide bar has been shogged sideways. The lateral movement is given along rods by an end reciprocation, so that the guides can give a sideways motion to avoid clashing with the needles as the thread is wrapped around the hook needle. ADVANTAGE - Acceleration, or periodical slowing down of the thread guide bar is not required, and this avoids clash of parts. The machine can attain higher speed

Patent DE-4224852-A1 (DE)
Inventor: HOELKEN FRITZ
IPC: E21D15/44
Filed: 1992-07-28
Abstract: The invention concerns a tubular prop (1) for use in underground mines and tunnel-construction sites. The tubular prop body (2) has, viewed in the vertical plane, at least one plastically deformable zone (10) and is filled with water either before or after being placed in position. To this end, the prop body (2) has a filler valve (5) and an associated air-vent valve (6) fitted in the vicinity of the end plate of the inner tube (3), thus ensuring that the interior (9) is completely filled with water. The downwards force resulting from the rock pressure is thus largely neutralized since the prop (1) can deform plastically in a pre-determined region and can also become shorter. The approximately 20 % stretch in the material results in a decrease of about 40 % in prop length, thus giving a prop (1) of this kind a high degree of resilience.

Title: Heterodyne diffraction optical interferometer - directs beam through input transmission grating on transparent block, and reflects off rear reflection layer to second reflective layer on input surface
Inventor: HAENSEL HARTMUT
IPC: G01B9/02
Filed: 1992-08-07
Abstract: The interferometer derives measurement information from the interference of two beams of different frequencies using a source location for each beam to produce sub-beams with at least partly coincident propagation directions. Each sub-beam has a common path with the associated sub-beam of the other frequency after passing along an interferometer arm. The source locations lie in different transmission grid structures (3,4) between which lie reflective layers (7,8) facing a second (2) of two carrier surfaces (1,2). The second surface contains transmission cross-grid structures (9,10) for the sub-beams of one frequency adjacent to the interferometer arm, reflection cross-grid structures for the other frequency's sub beams and central transmission grid structures for producing the common beam path. A beam path for the sub-beams passes between the carrier surfaces from the source locations to the cross-grid structures and via the reflection films to the transmission grid structures to form the common beam paths. USE/ADVANTAGE - For use in length measurement, heterodyne interferometer can be made conveniently and effectively in large numbers.
