  • Magnetic conditioners for treating liquids
    Patent number: 5468378
    Abstract: These improvements are applicable to conditioners fitted with three independent magnetic fields, each generated by a magnet or set of magnets (3, 5, 7) and consisting in coupling to the first magnet or set of magnets (3) an auxiliary magnet or group of magnets (17) using a telescoping shaft (16), which complementary magnet (17) will tend to move away from the first magnetic field (3) and will carry a front or conical plug (18) which may move to a greater or lesser extent depending on the stream of fluid running through the conditioner, such that the greater the stream of water, the closer this auxiliary magnet (17) is and the greater the intensity of the magnetic field in the area (20) where the water flows through between the permanent magnet or magnet group (3) and its magnetically permeable body (4).

  • Automated cassette loader
    Patent number: 5469310
    Abstract: An automated cassette loader system includes a front loading tape drive mounted in a standard height enclosure with a removable magazine including cassettes stored in front to rear alignment in two levels. The cassettes are pushed between entry and exit positions by pushing one cassette out of a push position in one level and then pushing a cassette from a push position in the other level. The cassette pushed out of the magazine is transported to the front loading tape drive and, when removed therefrom, transported to the intake of the other level of the magazine.

  • Servo controlled magnetic head positioner
    Patent number: 5452153
    Abstract: A magnetic recording head positioning system includes a Terfenol-D magnetostrictive rod prestressed by a lever arm to operate in a linear range to microposition the magnetic recording head in accordance with an electromagnetic field. The mechanical advantage of the lever arm amplifies changes in the magnetostrictive rod to position the head. The varying electromagnetic field is applied to the rod by a coil in response to a position error signal produced from servo data tracks on the magnetic tape. A permanent magnet system biases the magnetostrictive element with a DC field so that varying the field provides bi-directional motion of the magnetic recording head. The DC field also reduces coil current and size requirements.

  • Device for determining concentration-dependent electrophysiological parameters in a series of measurements
    Patent number: 5449492
    Abstract: The determination of concentration-dependent parameters in a series of measurements, in particular for the determination of dose-effect correlations, the solutions to be developed are each contained in chambers positioned on a round tray in radial symmetrically arrangement. The respective chamber just to be determined is moved underneath the measuring device via a gyratory movement of a round tray controlled by a computer and the vertical disk between the measuring device at the chamber to be measured is also lowered by computerized control so far until the measuring device dives into the solution in the chamber. The device to realize the process comprises a horizontally rotatable round tray as well as a lifting device wherewith either the total round tray including all chambers positioned thereupon can be vertically moved or only that chamber being immediately positioned underneath the measuring device.

  • Detection of analytes using fluorescent energy transfer
    Patent number: 5439797
    Abstract: The invention provides labeled proteins suitable for determining the presence of cAMP, other second messengers and organic molecules. The proteins are separately labeled with fluorochromes which, when in close spatial proximity, preferably, less than about 6 nm, interact through the transfer of energy from one fluorochrome to the other.A composition of matter, (S.sub.1.A).sub.n1 (S.sub.2.D).sub.n2 is provided wherein S.sub.1 and S.sub.2 are two proteins which are associated in one state and substantially disassociated in another, the equilibrium between which is controlled by the free concentration of an analyte, and A and D are fluorochromes, the emission wavelength of fluorochrome D overlapping the excitation wavelength of fluorochrome A and the distance between A and D being in sufficiently close proximity to allow the radiationless transfer of energy between the fluorochromes.

  • Broadband private automatic branch exchange
    Patent number: 5440554
    Abstract: A broadband private automatic branch exchange is to be implemented in which all broadband user stations can be switched like normal telephone terminals with all features of a conventional telephone private automatic branch exchange and without each broadband terminal requiring its own operator position. To achieve this, in accordance with the invention, all the broadband terminals (BB-E1, BB-E24) which are connectable via a broadband switching array (BB-V) to the subscriber line unit (TAE) of the public broadband network (VBN) are also connected like ordinary telephone user stations to a narrow band telephone private automatic branch exchange system (SB-PABX) which is connected via a signaling conversion module (VBNA) to the line unit (TAE) and which initiates the narrow band call setup and controls the broadband switching array for switching broadband calls.

  • Magnetic storage devices with dynamic boost adjustment to reduce read errors
    Patent number: 5438462
    Abstract: In a magnetic storage system, an error recovery is performed by reading the magnetic medium again with the filter programmed to a higher boost. If the retry still fails, the magnetic medium is read again with the filter programmed to a lower boost. The filter adjustment can be performed in combination with position adjustment of the read head, i.e. displacing the read/write head from the centerline of the track during error recovery to reduce read errors.
