Abstract: ABSTRACT OF THE DISCLOSURE        Block pattern detection circuitry for the read subsystem of a streaming tape drive system comprises a state machine, a pattern decoder, a tape mark detector, a block/gap filter, a block/gap meter, a verify count section, and a block read/verify section.  The incorporation of a hardware state machine within the block detect circuitry permits the application of historical detect data in the interpretation of present detect data.  This provides more certain pattern recognitions.  Also, state data is fed back to the block/gap filter allowing precise block boundary , triggers which are used by position capture circuity and the drive controller to effect more precise re-try positioning.  The use of the block/gap filter increases the detect circuitry's immunity to noise.  The advantage is enhanced where the block/gap filter uses stochastic thresholding, which is also advantageously employed by the tape mark detector.

Abstract: ABSTRACT OF THE DISCLOSURE          The invention relates to both a process and an apparatus for the control of a leakage cavity of a valve which is fitted with two sealing places which are disposed in series and in the closed position of the valve prevent the overflow of fluid from one valve casing part into another one, with the leakage cavity disposed between the sealing places and connected to the outside of the valve through the valve casing, wherein the closed position of the valve the connection of the leakage cavity with an inside space of the valve casing parts is sealed by a closing member cooperating with the two sealing places.          By the proposed process and the apparatus for its realization it is inter alia guaranteed that the connection between the leakage cavity and the inside space can be controlled also in positions other than the closed position of the valve.            This is achieved according to process technique in that the connection between the leakage cavity and the inside space in positions other than the closed position of the valve can be controlled in the same manner as in the closed position by a device which substitutes as to effect the closing member regarding its interaction with the leakage cavity.            An apparatus for performing the inventive process provides inter alia for this purpose that a locking piece (5) which is disposed to the closing member  (4)  relatively movable in direction of the degree of its freedom of motion, controls the connection between the leakage cavity (6) and the inside space (1,2) (fig. 21).            The invention in addition indicates solutions as to how a dynamically loaded seal assembly of a valve, particularly a valve of the category characterized in the introduction, can be cleaned without fault even in critical areas of the seals.

Abstract: AIR SUSPENSION DEFLATION CONTROL SYSTEM WITH AUTOMATIC  REINFLATION AND CONTROL RESET                 ABSTRACT OF THE DISCLOSURE     A vehicle having an air suspension system including air bags supporting the rear cargo area thereof, a deflation control system with automatic reinflation and control reset for manually actuated lowering of the rear cargo area to the minimum height to facilitate loading and/or unloading to the ground.  A manually operable control valve delivers an air pressure signal from a source to an inversion valve to exhaust the air from the air bags.  A normally open electrically operated air solenoid is interposed between the control valve and the air supply and shuts off air flow to the control valve when the ignition switch is activated to restore air pressure to the air bags.  The driver/operator can control the system only when the ignition switch is deactivated.  Thus the system provides for operator actuable deflation and automatic reinflation and control reset.

Abstract: A method and apparatus for reproducing an image and  transferring  same  onto  a  substrate.   A  positive cylindrical electrode is rotated about its longitudinal axis  at  a  substantially  constant  speed,   the  positive electrode having a passivated surface defining a positive electrode  active surface.   A  plurality  of  negative electrolytically inert electrodes electrically insulated from one another are arranged in rectilinear alignment to define a series of corresponding negative electrode active surfaces disposed in a plane parallel to the longitudinal axis  of  the  positive  electrode  and  spaced  from  the positive  electrode  active  surface  by  a  constant  pre-determined gap,  the negative electrodes being spaced from one anotner by a distance at least equal to the electrode gap to prevent edge corrosion of the negative electrodes.          The positive electrode active surface is coated with an olefinic  substance  and  a metal  oxide  to  form thereon micro-droplets of olefinic substance containing the metal oxide in an amount to prevent corrosion of the positive electrode.  The electrode gap is filled with a colloidal dispersion  containing  an  electrolytically  coagulable colloid.   Selected ones of  the negative  electrodes are electrically energized to cause point-by-point selective coagulation and adherence of the colloid onto the olefin and metal oxide-coated positive electrode active surface, thereby forming a series of corresponding dots of colored, coagulated colloid representative of a desired image.  The dots of colored,  coagulated colloid are  then contacted with  a  substrate  to  cause  transfer  of  the  colored, coagulated colloid onto the substrate and thereby imprint the substrate with the image.

Title: Apparatus and method for integrated sampling from closed and open sample containers
Inventor: UFFENHEIMER KENNETH F

Granted: 1995-09-26
Abstract: Integrated sampler apparatus and method are provided and include a sample liquid container support component which is operable to support both closed and open sample liquid containers thereon on a random basis.  Sample liquids from the open sample liquid containers are presented directly to a sample liquid analysis system probe for access thereby; while sample liquids from the closed sample liquid containers, which take the form of sample liquid containers closed by sample needle-pierceable stoppers, are transferred by virtue of a sampling needle assembly and connected sample liquid transfer conduits and transfer valve, to a sample liquid dispensing well for access by the same sample liquid analysis system probe.   Air segmented rinse liquid is provided for the sampling needle,  transfer conduits, transfer valve,  and dispensing well to minimize sample liquid carryover with regard to the sample liquids from the closed containers; and a surfactant is included with the rinse to lubricate the sampling needle to facilitate the piercing thereby of the closed sample liquid container stoppers and minimize the generation of sample liquid-contaminating stopper particles.  For use with aqueous sampler rinse liquids, hydrophobic sample liquid transfer conduits, transfer valve, and dispensing well surfaces are provided; and an isolation liquid which selectively wets those surfaces to the substantial exclusion of the aqueous sample and rinse liquids, is utilized in conjunction with the rinse liquid to further minimize sample liquid carryover.   The open sample liquid containers and the dispensing well are supported at essentially the same level relative to the probe to maximize sampling accuracy thereby. A  detector  is  provided  to  detect  sample  liquid identification as supported from the sample liquid container support component, and to differentiate between open and closed sample liquid containers for operation of the sample liquid analysis system probe in accordance therewith.
