Abstract: Magnetic tape apparatus with a servo bar (14) which is driven by a motor (40), can slide longitudinally back and forth and controls the functional parts of the apparatus, such as a head plate (3) and a loading mechanism (87). The motor (40) additionally serves for driving the hubs (42, 43). Furthermore, a control element (73) is provided, the position of which is determined by the servo bar (14) and the head plate (3) and, from its position, the position is derived of a rotary switching member (54), which operates switching means (60) for a logic circuit (46) of the motor (40), which couples the motor (40) non-positively to the servo bar (14) and which isolates the hubs (42, 43) from apparatus functions of the motor (40) during switching over.

Abstract: A system for rapid-scan spectral analysis comprising a concave holographic diffraction grating (18) continuously rotated at a substantially constant angular velocity to provide a rapid scanning monochromator (a monochromator is used to transfer nominal regions of wavelengths out of the continuous light source). The unique sampling circuitry uses an optical shaft encoder (42). The angular velocity and angular acceleration of the grating (18) are calculated from time measurements, just before the first wavelength of interest falls on the detector. This information is used to control the Analog to Digital converter sampling rate across the region of interest. The samples as a function of time are stored in a memory buffer (58) so that each data point corresponds to a wavelength.

Abstract: A method of making a papermarker's felt which includes the steps of forming a pin seam fabric (1) having interdigitated loops (4) at the ends of the fabric joined by a pin (5). A batt of fibrous material (6) is needled into at least one face of the fabric (1) and across the pin seam joint. When the felt is to be installed on the papermaking machine, the pin (5) is removed and the felt is bent back on itself at the joint to bring the portions of the batt (6) adjacent the joint into contiguous or contacting relation and cause the loops (4) to separate. The batt (6) is then cut along a line extending through the separated loops (4) to provide a flat or opened felt which can then be installed on the papermaking machine. After installation, the loops (4) are interdigitated and the pin (5) is reinserted through the loops (4) to provide the endless felt construction.

Abstract: A flowing gas laser (11), of the kind in which gas flows continuously through the lasing region and is circulated through the heat exchanger (87) for cooling before being returned to the lasing region, comprises a resonator module (13) and a blower module (15). The optical components of the laser are mounted on an outer surface of the resonator module, and the resonator module has an interior structure for conducting the circulating gas to the lasing region. The blower module has heat exchange structure for cooling the circulating gas and has a blower for pumping the circulating gas. The blower module is physically separated from the resonator module to prevent the heat and vibration of the blower module from distorting or otherwise affecting the structure or the performance of the optical components. Ducting (17, 19) interconnects the resonator module and the blower module for circulating the gas between these modules. Precision bore and pin structures are used for mounting all of the support structure for the laser at predetermined, fixed positions on the resonator module without the need for subsequent adjustment of such support structure.

Title: Process for preparing sugar syrups by a direct enzymatic saccharification of raw starch-containing materials, especially from fresh or dried cassava roots
Inventor: SARHADDAR SCHAHROCH DIPL ING
IPC: C12P19/14
Filed: 1988-01-25
Abstract: The process consists in a direct hydrolysis of the starch contained in the raw materials, in which water-soluble contents are first washed out of the raw material and the raw material is then treated under mild conditions at temperatures below 100 DEG C without prior isolation of the starch. The starch contained is made into a paste, enzymatically liquefied and then saccharified. The solids are removed from the saccharified mash, and the juice obtained is purified with active carbon and finally desalted. The washing water obtained during the removal of the solid is employed as diluting water in the decomposition of starch.

Abstract: The present invention discloses a noise measurement method and system in a television signal receiver. The receiver has a noise reduction circuit and receives a composite television picture signal which contains noise, picture information, a trigger pulse (preferably the Vsync pulse), a horizontal synchronizing pulse and a standard signal adjacent in time to and later than the horizontal synchronizing pulse. The preferred standard signal is a back porch signal or a color burst signal. A comparator (20,22) receives at least two samples of the standard signal and produces a comparison signal that is representative of the comparison of the two standard signal samples. Preferably the two standard signal samples are from two different scan lines. An accumulator circuit (27) receives the comparison signal and generates a measured noise signal that is used to control the noise reduction circuit.

Abstract: There is disclosed an athletic shoe having grooves in a ground engaging surface of a sole formed concentrically about a pivot point in the ball portion and having traction projections in the form of bris­tles or columns embedded in the bottom of the grooves. Free ends of the traction projections protrude from the ground engaging surface whereby forces on the free ends of the traction projections perpen­dicular to the grooves, as when a player is accelerating, causes the projections to bend against the side walls of the grooves which thus support the projections against further bending with the free ends of the projections protruding from the outsole to provide traction. Forces on the free ends of the projections tangentially to the grooves, as when a player pivots, cause the projections to bend into or lay down in the grooves and thus offer little or no traction. The ground engaging surface of the sole is formed of a material having a low coefficient of friction so that the sole can move or pivot relatively freely once the projections have bent into the grooves.
