Abstract: A loading mechanism for an apparatus for recording or reproducing information using an information disc, which mechanism includes guides for the disc edge. The guides include a supporting guide constructed as a support for the disc edge pressed against it and a loading guide constructed as a rotationally drivable transport wheel, which rolls the information disc into and out of the apparatus for the purpose of loading and unloading, respectively, the supporting guide and the loading guide guiding the information disc along a loading path. The loading mechanism has minimal dimensions and enables the information disc to be loaded and unloaded without the surface of the disc being touched. This is achieved by the supporting guide and the loading guide being supported so as to be movable in a loading plane.

Abstract: A voltage isolating device selectively electrically isolates from each other two points (13 and 15) of an electrically conductive flow medium having different electrical potentials along a flow path. The electrically conductive flow medium is conveyed in the inner space (18′) of a freely protruding carrier (17′) having at least one discharge opening (29). The carrier (17′) moves back and forth between a first isolating position and a second docking position to allow a transfer flow. The discharge opening (29) is closed until the docking position has been reached, wherein the discharge opening is opened, and is closed again when the carrier is moved out of the docking position.

Abstract: A detachable and adjustable adapter assembly for directing fluid flow into and out of a housing is disclosed.

Abstract: An internally plumbed housing for containing fluid purification media especially suitable for the production of ultrapure water. The device may be installed in a system for the production of laboratory grade water or may be used with pressurized feed for the delivery of purified water or other fluids in multiple applications.

Abstract: Loading mechanism for loading and unloading an information disc into or from an information-technology apparatus in which first and second guides have respective first and second grooves each provided for engaging the edges of the information disc, and the second guide includes a rotationally drivable transport wheel which rolls the information disc into and out of the apparatus along a loading plane for the purpose of loading and unloading, and the first guide and the second guide are supported so as to be movable, and the first groove and second groove each have respective pressure faces inclined relative to the loading plane, and the first and second grooves each having a circumferential bottom surface and a minimum gap dimension where the respective circumferential bottom surfaces each extend substantially perpendicularly to the loading plane, and the respective minimum gap dimensions are each selected to be smaller than the thickness of the information disc, and wherein, during the loading process, the c

Abstract: Methods of maintaining animal cells for product production, for supporting hepatocyte function and viability to treat a patient suffering from hepatic failure and for preserving tissue-specific function of mammalian cells are carried out with a bioreactor containing a feed and waste chamber and a cell chamber separated by a selectively permeable membrane. Within the cell chamber, a biocompatible contracted three-dimensional gel matrix entraps animal cells or genetic modifications thereof, and a liquid phase contains a concentrated solution of the cell product. The bioreactor uses only two chambers to achieve three distinct zones within the bioreactor. The bioreactor can be of either hollow fiber or flat-bed configuration. In the configuration using hollow fibers, the two fluid paths correspond to the cavity surrounding the hollow fibers (the extracapillary space), and to the lumens of the hollow fibers themselves. Both fluid paths have inlet and outlet ports.

Abstract: A test pattern produced by a television signal generator includes picture elements derived at least substantially from helper lines, and vertically adjacent picture elements of substantially different luminance derived at least substantially from the main picture lines, so that the engineer can readily determine by visual inspection whether or not the helper lines are being decoded.

Abstract: A magnetic-tape-cassette apparatus, with a detection mechanism in order to handle magnetic-tape cassette types (3, 13) with different tape-recording standards and housing configurations, which detection mechanism senses the cassette side wail (8, 17) having the access openings (8, 17) and comprises a sensing element which upon insertion of a cassette, depending on the cassette type, either moves past this cassette wall (8, 17) or engages a guide profile in order to be positioned before a sliding cover of this cassette type and move said cover so far that the access openings are exposed, the detection mechanism (41) being activated upon insertion of a magnetic-tape cassette in a longitudinal direction in which the tape spools are juxtaposed in that the short side wall which faces forward during insertion moves the sensing pin without the sliding cover at this instant already being urged towards the position in which it exposes the access openings, and as insertion proceeds the sensing pin moves to the long cas

Abstract: The invention relates to a magnetic-tape-cassette apparatus having a deck for playing magnetic-tape cassettes, which comprises a loading mechanism including a cassette holder (23) adapted to receive a magnetic-tape cassette (2) and having a holder wall (23e) which guides a cassette wall and which carries laterally projecting pins (23a/b), which pins are guided in lift slots (22b) in a lift slide (22), which slots are inclined relative to the vertical, to lower the cassette holder (23) into a play position and to lift the holder into an eject position, the lift slots (22b) being formed in a lift wall of the lift slide (22), which is movable between a forward and a backward end position, which carries along the cassette holder (23) over a part of its path of movement, and which is movably guided in a parallel first and a second rail (1f, 1n) on the deck plate of the apparatus, in whichthe first rail (1f) is arranged at the location of the lift wall provided with the lift slots (22b) through which the pins (23a/

Abstract: A guitar tailpiece assembly includes a tremolo device by which the strings may be stretched or relaxed in an oscillating manner and which also minimizes the tendency for some of the strings to shift out of tune as a result of using the tremolo device or when "bending" a note. The tremolo device includes means by which all of the strings can be retuned simultaneously, for example, when transposing the tuning of the guitar so that it is in tune with another instrument.
