Title: Ink jet printing apparatus
Inventor: CARLOTTA MICHAEL
IPC: B41J2/175
Filed: 1991-08-23
Abstract: In an ink jet printer, a printhead assembly comprising a printhead and an ink reservoir is mounted on a scanning carriage for movement across a recording medium. During printing, droplets of ink are expelled from ink channels within the printhead and the channels are replenished with ink which is drawn in from the reservoir. The reservoir is connected to an ink source from which ink is supplied during printing and when the printhead assembly is being primed. A partition within the reservoir ensures that, during priming, air can be expelled from the reservoir through the ink channels, thereby avoiding the need for an air vent from the reservoir.

Title: Process and device for cleaning of bulk goods
Inventor: SCHOTT HANS K
IPC: B22C5/00
Filed: 1991-10-10
Abstract: ABSTRACT OF THE DISCLOSURE           The present invention concerns a process and a device  for  cleaning  the  grain  surfaces  of  contaminated granular bulk material.  The invention is particularly suited to final-cleaning of, in particular, thermally pre-regenerated sand (for example used foundry sand).  According to the method of the invention, the bulk materials which are to be cleaned or final-cleaned are charged with a high pressure gas flow which maintains a fluidised bed of the bulk material, and creates a condition of turbulence within the fluidised bed in such a way that cleaning takes place while avoiding excessive impact or rebound stresses on the grains.  Cleaning of the grains occurs primarily at the walls (which may be fixed or movable) only by friction or scouring stress on the grain surfaces.  The device of the invention is equipped with a container having an inlet and outlet for bulk materials and a gas-permeable flow bottom for forming a fluidized bed.  The device includes at least one nozzle, which is located above the flow bottom, and which is connected to a high-pressure gas source.  The nozzle serves to direct the high-pressure gas flow into the interior of the fluidized bed.

Inventor: SHIELDS MARY
IPC: A61G7/07
Filed: 1991-11-05
Abstract: The posture board according to the present invention is contoured to a spinal mating shape.  The board comprises an upper back supporting portion having a leading edge and a lower back supporting portion terminating in a trailing edge.  The board has a longitudinally extending sine wave configuration with an up curve at the lower back supporting portion.  The board further has a side to side concave curvature defining a trough like center region and upwardly turned outside edges.  The center region along at least part of the upper back supporting portion and at the trailing edge is in contact with the supporting surface on which the posture board is used.  The up curve defines a gap beneath the center region along the lower back supporting portion and the supporting surface.  The outside edges of the board are more flexible than the center region to allow some edge flattening while the center region is much less flexible to prevent lengthwise full flattening of the board at the center region under weight of a user such that the board provides vibratory feedback responsive to body vibrations given off by the user.

Title: Scsi device drivers for multitasking operating system
Inventor: FERIOZI DAN T
IPC: G06F9/46
Filed: 1992-01-23
Abstract: A tiered device driver system includes a SCSI generic device driver  (SGDD)  in one  tier  and one  or more  SCSI device-class drivers (SDCD) in another tier.  In response to a request to access a SCSI  device,  the operating system creates a request packet that is passed to the appropriate SDCD.   Such  SDCD  creates  a  generic  request  packet  and associated data structures that contain information specific to the SCSI  device being accessed.   The generic  request packet is passed on to a SCSI generic device driver (SGDD) that creates a SCSI ABIOS request block which it transmits to a SCSI adapter for accessing the desired SCSI device. The SGDD provides functions common to the SDCDs.

Abstract: TITLE OF THE INVENTION HBsAg ESCAPE MUTANT VACCINE       ABSTRACT OF THE INVENTION     In order to produce serologic variants of hepatitis B virus (HBV) surface proteins in the form of particles with substantially reduced entrapped carbohydrate content, DNA encoding the HBV variant envelope proteins was expressed in a recombinant yeast hosts which are either wild type for, or deficient in their ability to glycosylate proteins. These HBV surface proteins display the variant antigenic sites genetically encoded by the S domain of the HBV virion envelope open reading frame and contain substantially reduced levels of entrapped carbohydrate when compared with HBsAg particles produced in "wild-type" yeast cells.  These particles are useful as a vaccine for both the active and passive treatment or prevention of disease and/or infection caused by HBV or other agents serologically related to HBV and as diagnostic reagents and immunogens and antigens for developing diagnostic reagents.

Genomic deoxyribonucleic acid (DNA) is extracted from intestinal epithelia and mucosa of vaccinated birds and amplified using the polymerase chain reaction (PCR). The reaction allows efficient amplification of fragments from every small subunit ribosomal RNA (ssrRNA) gene in the target pool. Unique species-specific hybridization probes complimentary to sequences within the heterogeneous pool of PCR products are used to quantitate the relative levels of each of the Eimeria species in the infected hosts. The same unique probes are used to identify and quantitate species specific ssrRNA sequences in total RNA extracted from intestinal epithelia and mucosa of vaccinated chickens. The same unique probes are also used to identify and quantitate species specific ssrRNA sequences in genomic DNA isolated from mixed oocyst population purified from decal material obtained from vaccinated chickens.
