Abstract: A gas seal for a shaft in which both the stator sealing ring and the rotor sealing ring are composed of materials having high strength,  high modulus of elasticity,  high hardness and high thermal conductivity.  The rings have pore volumes of less than 1% and a surface roughness of less than 0.02 micrometers (Ra) and the polar moment of inertia of the stator ring is such as to resist temperature-dependent torsional deformations  of  its end  face.          Under these conditions, leakage can be minimized without regard for a pressure distribution in the dynamic gas seal gap to generate torsional deformation counteracting moments.

Title: Vehicle restraint
Inventor: CARLSON DENNIS L
IPC: B65G69/00
Filed: 1988-05-13
Granted: 1992-02-25
Abstract: VEHICLE RESTRAINT              Abstract of the Disclosure A vehicle restraint for preventing a vehicle or truck from accidentally pulling away from a loading dock.  The truck restraint comprises a frame to be mounted on the vertical front face of the loading dock and a restraining means is mounted for pivotal movement in a generally vertical plane parallel to the dock face between a first lower storage position and a second operative position where the restraining means will prevent outward movement of the truck away from the dock.  A curved plate or abutment is mounted in spaced relation to the frame and extends throughout the length of the path of pivotal movement of the restraining means.  The restraining means is normally disposed out of contact with the abutment as the restraining means pivots between the storage and operative positions.  In the event the truck attempts to pull away from the loading dock while the restraining means is in the operative position, the outward force applied by the truck to the restraining means will deflect the re-straining means outwardly into contact with the abut-ment to thereby restrict further outward movement of the restraining means.  The restraining means is urged to the operative position by a resilient biasing member and the biasing member is movable between a first posi-tion where the force of the biasing member overcomes the weight of the restraining means and acts to urge the restraining means to the operative position, and a second position where the force of the biasing member is overcome by the weight of the restraining means so that the restraining means will move by gravity to the storage position.

Title: Container filling system
Inventor: BERG MARVIN I
IPC: B65G53/30
Filed: 1988-08-03
Granted: 1992-05-12
Abstract: CONTAINER FILLING SYSTEM         Abstract A container filling system is disclosed that produces controlled volumes and weights of filler material for discharge into containers. The systemincludes a material feed subsystem that provides a source of longitudinally aligned filler material of uniform density. A rotating measuring subsystem includes measuring chambers that receive predetermined amounts of the material for transfer to a discharge subsystem. The material is transferred into the measuring chamber in an axial direction and is transferred for discharge into the containers in the same direction. More particularly, the rotating discharge subsystem includes a plurality of discharge stations that receive both the measuring chambers and containers immediately below the chambers. Plungers are supported above the measuring chambers and are vertically controlled by a cam tomove downward with rotation of the discharge subsystem. As a result, the material is forced from the measuring chamber into the container. Continued rotation of the discharge subsystem effects the removal of the container from the discharge subsystem and the transfer of the measuring chamber back to the measuring subsystem.

Abstract: ABSTRACT OF THE DISCLOSURE.       To provide a cleaning arrangement which includes brushes brushing against the surface of a rubber blanket or other printing cylinder, to remove lint, dust, dirt and other contaminants  therefrom, a strip of brushes  (9), preferably backed up by a suction pipe (8) to remove lint from the surface of the cylinder   and from the brushes, is located inwardly of the finger guard strip (6) which is provided in advance of the nip between rotating cylinders as a safety  measure. The cleaning  elements, that is, brushes (9) and suction tubes (8), if provided, are located inwardly, with respect to the nip, of the safety guard or safety rail (6) which, typically, has angled or essentially in cross section part-circular, typically semi-circular shape. The safety guard is usually supported by levers (11) or slidably supported in the printing machine, to be placed out of position from the nip when the machine is stopped. The cleaning elements, that is brushes and suction tube, if provided, move with the safety rail to provide access to the nip between the cylinders when the machine is stopped. The cleaning structure does not require additional space or holding elements in the machine since the holders (11) for the safety guard rail (6) likewise support the cleaning elements (8, 9).

Abstract: ABSTRACT OF THE DISCLOSURE      An acknowledge back (ack-back) pager is provided for use in a paging system including a central station which transmits a group of message signals to a group of ack-back pagers which are addressed as a group.  The users of the group of addressed ack-back pagers indicate a response to their respective pagers thus providing ack-back data.  The pagers in the group of addressed ack-back pagers then simultaneously transmit back to the central station their ack-back data on different frequency sub-bands, a different frequency sub-band being allocated to each of the pagers in the group.  To accurately control the ack-back transmit frequency, the pager receives and down-converts the FRX signal thus producing a down-converted FC signal, the frequency of which is measured and stored.  The pager selects which sub-band of a plurality of frequency sub-bands within a predetermined range of frequencies is to be used for transmission of the ack-back signal.  The pager determines a frequency offset FD corresponding to the selected sub-band, such offset being with respect to a predetermined frequency within such range of frequencies.  The pager generates an acknowledge back signal at a frequency (FC + FD) -FCTX and up-converts such signal to a transmit frequency FTX corresponding to said selected sub-band, FCTX being the frequency of a down-converted sample of the FTX signal.

Inventor: ALAM RAFEUL
IPC: C07K14/52
Filed: 1989-01-12
Granted: 1995-03-07
Abstract: The present invention relates to a novel inhibitor of histamine release, designed HRIF which is believed to represent a promising therapeutic agent for treatment of basophil and mast cell dependent disorders, including allergic diseases. This inhibitor is a human cytokine that antagonizes a human histamine releasing cytokine(s) designated HRF. HRIF has a molecular weight of about 8,000 to 10,000 daltons as determined by gel exclusion chromatography and has also been purified by ion exchange chromatography. HRIF is stable when heated at 60°C. for one hour, when frozen and thawed four times, and when treated with neuraminidase. Treatment with trypsin or chymotrypsin substantially destroys the activity of HRIF. The present invention includes compositions comprising substantially purified HRIF as well as methods for HRIF production and use. The invention also includes HRlF-producing cell lines and methods for producing such cell lines.
