Abstract: In the rotary filter press, a rotor 4 having fins 5 is provided and the leading edges 13 of the fins 5 brush over a leading edge surface, in which a stator 6 supports a filter medium 7, which with a leading surface 12 lies opposite the leading edge surface 13 at a distance, and in which a substance between filter medium 7 and rotor 4 forms a closed circular flow pattern, and the filter medium 7 is maintained free from sediment. It is required that the freedom from sedimentation is maintained over an extended period of time. This is achieved by changing the distance between the leading surface 12 of the filter medium 7 and the leading edge surface 13 of the rotor 4 in a radial direction so that eddies 11 are formed in the circular flow pattern. Changing the distance increases the time period during which the filter medium is free from sediment and increases the filling level possible in the chamber for material to be filtered. <IMAGE>

Abstract: A laser end point detector incorporating adjustable-focus, variable-orientation detection optics for monitoring different types of structures such as laser-transparent thin films, isolated trenches or holes and patterned arrays of trenches or holes. A collector lens package comprising a laser and a focusing lens are mounted in a hole in a collector lens which is pivotally mounted for selectively focusing zero, first and higher orders of diffractions reflected from the wafer onto an associated detector to monitor the etching of different types of structures. For example, zero order diffraction signals are used to monitor the etching of large target areas in transparent thin films or of non-patterned trenches of holes. First order (or higher) diffraction signals are used for monitoring the etching of patterned features which effect a two-dimensional diffraction grating, such as the capacitor holes in dynamic random access memories.

Abstract: The hydraulic shock absorber for industry has a piston rod (1) with a piston (15), into which a throttle aperture (21) is inserted, which, together with a matched throttle needle (19) causes increasing damping of the piston rod movement. In order to compensate for the volume of oil which is displaced when the piston rod is pushed in, a membrane (9) is mounted on a membrane support (6), whose position is fixed with respect to the housing (7), oil passing between the housing inner wall and the membrane and curving the latter inwards. The part of the throttle needle (36 - 41) which interacts with the throttle aperture has, apart from the tip (41), five conical steps (36 - 40) which have a progressive deviation up to 15 DEG  with respect to the cylindrical jacket which is intended as an extension of the cylindrical part (35) of the needle. Such a hydraulic shock absorber is in general used in automatic handling units and has a long life on the one hand and good reproducibility and reliability on the other hand, as well as smooth and efficient damping.

Abstract: This invention uses a new method of producing ionic metallocene compounds. These compounds are useful as catalysts for polymerization of olefins, primarily propylene. This method uses an ionizing agent which ionizes the neutral metallocene compound. The ionizing ionic compound does not contain an active proton and contains a carbonium, oxonium or sulfonium cation. The anion of the ionizing ionic compound is not coordinated or is only loosely coordinated to the metallocene cation and is chemically unreactive with the metallocene cation. One such compound is triphenylcarbenium tetrakis(pentafluorophenyl)boronate. The process of making catalysts with this invention produces catalysts having high activity and does not produce by-products which can inhibit catalyst activity. This new synthesis is a clean reaction which does not produce a Lewis base. The process generates active catalysts by removing a methyl anion from a group IV metallocene derivative.

Abstract: Three related embodiments of audio signal dynamic range circuits for consumer and semi-professional audio signal compressors, expanders, and compressor/expander noise reduction systems incorporate certain basic features of professional Spectral Recording (SR) while adapting SR for use with consumer recording media (particularly audio cassette tape) and reducing the cost and complexity of the SR circuitry. In addition, the three embodiments, and particularly the preferred embodiment, provide substantial compatibility with the existing B-type and C-type consumer and semi-professional noise reduction systems. Subjective performance substantially equivalent to 16-bit PCM audio systems is achieved with analog audio cassette tape media. In all three embodiments there are two cascaded stages: (1) a high-level stage a high-frequency fixed-band/sliding band action-substitution sub-stage (324A) and a low-frequency fixed-band sub-stage (328A) and (2) a low-level stage having only a high-frequency fixed-band/sliding band action-substitution sub-stage (326A). The dynamic action regions of the high-frequency action-substitution sub-stages are staggered. Each of the high-frequency sub-stages provides up to 12 dB of dynamic action (together providing up to 24 dB of dynamic action) and operates in a frequency band defined by a single-pole filter having a high-pass shelving response with a corner frequency of 400 Hz. The low-frequency sub-stage provides up to 10 dB of dynamic action and operates in a frequency band defined buy a single-pole filter having a low-pass shelving response with a corner frequency of 200 Hz. The single-pole filter characterisctics provide a broad and smooth overlap of the high-frequency and low-frequency characteristics. Particular forms of spectral skewing and antisaturation enhance the performance of the circuits with consumer recording media.
