Title: Carrier for data storage disk
Inventor: STARK DANIEL J
IPC: G11B17/04
Filed: 1987-09-28
Granted: 1992-06-02
Abstract: CARRIER FOR DATA STORAGE DISK ABSTRACT Disclosed herein is a carrier for a data storage disk.  Such carrier comprises means for releasably capturing A disk so that it may be removed by a suitable disk release mechanism and used at a location spaced from the carrier, thereby avoiding any potential for disk damage due to contact with the carrier during disk rotation, and avoiding the need to precisely locate the carrier with a disk drive unit.  Preferably, the carrier features enabling disk release are located so the disk release can be effected by the same disk-releasing mechanism no matter which of four different orientations the disk carrier has when inserted into the disk drive unit.

Inventor: VOLEJNIK WILHELM
IPC: H04L7/033

Granted: 1991-09-10
Abstract: Abstract Disclosed is a method for recovering the clock and/or the clock phase of a synchronous or plesiochronous digital signal.          At the inputs of devices for transmitting or processing digital signals, their clock must be recovered.  The new method is intended to provide the possibility for arrangements which can be implemented to the greatest extent by means of logic circuits in "gate arrays" or "cell arrays".  In an auxiliary clock generator, an auxiliary clock is generated or auxiliary clocks (HT1,HT2) of the same frequency but different phase relationship extracted from it are generated which, conducted via a phase correction facility, produce an auxiliary data clock (DHT) as recovered clock.  In principle, the frequency of this auxiliary clock or of these auxiliary clocks (HT1,HT2) deviates from that of the auxiliary data clock (DHT) to be formed.  A phase sensor checks whether the active edges of the digital signal (DS) and of the auxiliary data clock (DHT) have approached each other to less than a defined time interval and emits a correction signal (K) as soon as this is the case.  This signal cause  a phase shifting of the auxialiary data clock (DHT) to be effected in the phase correction facility by switching between the extracted auxiliary clocks (HT1-HT2) and/or by reversing the polarity of the auxiliary clock or of the extracted auxiliary clocks (HT1,HT2).  The method can be used in digital signal multiplex devices and distributor multiplexers.

Title: Glow plug alternator control
Inventor: VERHEYEN MICHAEL R
IPC: F02P19/02
Filed: 1987-11-27
Granted: 1991-05-14
Abstract: Abstract of the Disclosure Glow Plug Alternator Control The present invention pertains to a control system for igniting devices used in an internal combustion engine.  In order to ignite alcohol fuel in a diesel engine, the fuel must be heated before or during compression.  Glow plugs conveniently provide heat, but have a short life in such continuous applications.  Glow plugs must be accurately controlled to prevent overheating, which leads to open-circuiting.  Individual constant voltage controls attempt to provide this function, but are only moderately successful.  They are costly and complex, and provide only moderate protection from overheating. Since glow plug resistance correlates to glow plug temperature, resistance control provides better protection against glow plug overheating.  Therefore, an apparatus monitors the resistance of a single glow plug, and controls the resistance of each glow plug to a preselected resistance value.  This preselected resistance value represents a glow plug temperature, that provides satisfactory fuel combustion combined with improved glow plug life.  The principal use of the apparatus of the present invention is with internal combustion engines using alternate fuels.

Granted: 1991-09-17
Abstract: Abstract A static var compensator which includes a transformer with one end connected to an electric power system, and a series circuit made up of a reactor and a thyristor bulb connected between the other end of the transformer and ground.  A voltage detection device detects the voltage of the electric power system and the output of the voltage detection device is sampled an even number of times for every cycle of the voltage.  A register is provided for storing sampled values an adder is provided for adding absolute values of the sampled values stored in the register.  A firing angle of the thyristor bulb is controlled by a control device in accordance with a deviation of an output of the adder from an output of a voltage setting device.  A deviation deriving device obtains a deviation of an output of the control device from a predetermined value corresponding to a present var, and an output of the deviation deriving device is fed back to an input side of the control device.

Granted: 1991-07-09
Abstract: ABSTRACT OF THE DISCLOSURE          An improved switching arrangement 10 for waveguide is disclosed which comprises, in combination, a coaxial switch 12 and a unified, multi-port, waveguide interface 14.  The coaxial switch 12 has coaxial connectors of a first type (12a, 12b, 12c) mounted in a parallel pattern with a preestablished center-to-center spacing.  The waveguide interface 14 includes flanges (14a, 14b, 14c), and is preferably formed as a waveguide housing having a transition plate portion and a cover plate portion.  Each port of the unified waveguide interface includes internal waveguide-to-coax transitions for coupling to a respective external connector of a second type.  The external coaxial connectors (16a, 16b, 16c) are configured in a parallel pattern with center-to-center spacings equal to the preestablished center-to-center spacings of the coaxial switch connectors (12a, 12b, 12c) such that these connectors mate directly with those of the unified waveguide interface.  By so doing, intervening coaxial cables or adaptors are eliminated and relatively low insertion loss and fast switching speed are exhibited over a relatively broad bandwidth.        In an exploded view of the first embodiment, depicted at 20 in Fig. 2, the waveguide-to-coax transitions are in the form of multi-stepped impedance transformers (26a-26e) suitable for bandwidths approximating an octave. In an exploded view of the second embodiment, depicted at 30 in Fig. 3, the waveguide-to-coax transitions are formed without steps but are constructed and arranged to have a back partition (22, 23, 24) in proximity to an electric probe, each formed by a center post 34 surrounded by dielectric 32 which is part of a miniature coaxial connector (16a, 16b, 16c).

Granted: 1992-07-28
Abstract: ABSTRACT OF THE DISCLOSURE        Rotating fluid-handling apparatus, e.g., a centrifugal separator has at least first and second elements which rotate relative to the other about a common axis.  A seal assembly provides fluid-tight sealing between the elements, which define passages for fluid flow from one element to the other.  The seal assembly has at least one annular seat carried by one of the elements coaxially with the axis, and an annular seal, the other of the elements defining a chamber for the seal in proximity to the seat.  The chamber carries the seal within it coaxial with the axis, the seal being shiftable axially within the chamber between positions, in and out of sealing contact with the seat.  Sealing contact with the seat is provided over an annular sealing surface area.  The seal and chamber are mutually configured for causing fluid flow from one element to the other through the passages for producing shifting of the seal from the out-of-contact position to the in-contact position to cause the sealing surface area to be maintained in fluid-tight, fluid-lubricated relationship with the seat in response to pressure produced by the fluid flowing from one element to the other during rotation, yet permitting shifting of the seal to the out-of-contact position in the absence of said pressure, so as to avoid fluid-unlubricated contact of the seal with the seat.
