Title: Lithographic dampener
Inventor: HAYES THOMAS
IPC: B41F7/26
Filed: 1990-10-11
Granted: 1995-02-14
Abstract: An improved lithographic dampener of the type having continuous plate/form roller/metering roller contact, adaptable to a variety of press configurations and operating speeds, employs a friction-driven oscillator roller that distributes added dampening liquid and the ink/liquid emulsions on the metering roller, to avoid continuing patterns which might cause ghosting in printed images. The dampener has a simple drawer-like configuration, with an open front for improved range of form roller/plate contact. A pan with a remote supply of dampening liquid, is located under the rollers such that the metering roller surface contacts and picks up liquid from a pool in the pan. Simplified seal dams at the ends of the form/metering rollers' nip keep the reservoir of liquid in that nip, yet minimize wear of the seal configuration. A slide block mounting of the metering roller and oscillator rollers allows independent adjustment of pressure at the form/metering rollers' nip, and at the metering/oscillator rollers' nip.

Title: Process and apparatus for packaging a stack of flat objects
Inventor: WINNEMOLLER ALOYS
IPC: B65B11/12
Filed: 1992-02-06
Granted: 2002-12-10
Abstract: To package a stack of flat objects, preferably a stack that is composed of bags provided with handles and has a height exceeding the width of a bag, the stack is wrapped by a section of a web of paper of plastic and the marginal portions of the web section which overlap on one side face of the stack are adhesively bonded to each other to form a tubular wrapper around the stack. The end portions of the wrapper which protrude from the ends of the stack are folded onto the end faces of the stack so as to form folded corner portions, which are folded onto and adhesively abonded to one side face of the stack. To permit a packaging by means of simple apparatuses, one side portion of each protruding end portion of the tubular wrapper is first folded onto the adjacent open end face of the stack about the longer edge of said end face, the adjacent ends of each protruding end portion of the wrapper are pulled out and flattened into the plane of the infolded side portion so that the apposite side portion of the protruding end portion is folded about the opposite longer edge of the adjacent end face of the stack onto said end face and folded corner portions protruding from the stack are thus formed. Folded corner portions are then folded onto and adhesively bonded to the wrapper on those side faces of the stack which adjoin the initially open side face of the stack.

IPC: B65H19/22
Filed: 1991-08-29
Granted: 2003-03-11
Abstract: In order to roll up paper or cardboard webs, reelers with two king rolls (1, 2) are known, in which the web (5) is deflected by one king roll (1) and is guided upwar-dly through the gap between the king rolls (1, 2). In order to replace the reels (4), the known reelers have, besides a device for severing the web (5), a device for stopping the web (5) that can be raised through the gap between the king rolls (1, 2) and put against the reeled king roll. According to the invention, a raisable and lowerable sup-port (12) that extends over the whole working width is arranged below the gap be-tween the king rolls and carries at its upper and lower ends freely rotatable deflection pulleys (14, 16) around which revolves at least one elastic belt (17). The upper deflec-tion pulleys (14) can be moved into the gap between the king rolls and the lower def-lection pulleys (16) are so arranged that during raising a strand (17.1) of the belt (17) lies flatly on the king roll (L) around which the web (5) is reeled.

Title: Multi-layer fluid curtains for furnace openings
Inventor: SHARMA SUDHIR KUMAR
IPC: F27D99/00
Filed: 1992-07-03
Granted: 1997-03-18
Abstract: An apparatus and method for providing a selected atmosphere at and within an opening to the interior volume of a furnace.  Two or more paralleled diffusers adjacent to the furnace opening laminarly emit different fluids and provide a multi-layer fluid curtain over the opening.  The curtain has a composite modified Froude number from 0.05 to 10, and a thickness at emission of at least 5% of its extent in the flow direction.  Partially covering the outside of the curtain is an optional, substantially flat, outer shield with an aperture coinciding with the furnace opening, which reduces the necessary flow rates of fluids.  Optional side shields around the sides of the curtain also reduce the necessary fluid flow.         A preferred diffuser comprises a porous tube in a housing with an outlet directed to emit fluid across the furnace opening.  The outlet is covered with a screen to disperse the fluid flow and to protect the porous tube.

Title: Cassette seal
Inventor: JOHNSTON DAVID ERNEST
IPC: F16J15/3256
Filed: 1992-07-27
Granted: 1999-03-23
Abstract: A cassette seal for sealing the gap between a bore wall and a shaft includes an inner ring fastened to the shaft and having a radially outwardly open groove, an outer ring fastened in the bore and having a flange type radial projection extending into the groove and a sealing lip of polymeric material fastened to the radial projection in the region of the inner circumference.  At least the inner ring 19 made of plastically deformable sheet metal.  The inner ring is one single part and is provided at both axial ends with radially outwardly directed annular projections made by plastic deformation.  The groove is defined in axial direction by mutually opposed axial surfaces of the annular projections. The sealing lip rests against the inner ring in the region of one axial end surface.  The outer ring is at both axial ends provided with circumferentially spaced apart spacers of polymeric material which rest against the axial end surfaces in the unused condition of the cassette seal.  The cassette seal has a small number of easily assembled parts, which provides for an especially economical manufacture, and has exceptional operating characteristics, since a transport of the sealed-in medium back into the space to be sealed is reliably achieved.

Title: Peptides stimulating cytotoxic t cells immune to hiv rt
Inventor: BERZOFSKY JAY A
IPC: C07K14/16
Filed: 1991-03-08
Granted: 1997-06-03
Abstract: An epitope in the human immunodeficiency virus-1 (HIV-1) reverse transcriptase that is conserved among HIV strains and that is recognized by both murine and human cytotoxic T cells has been identified. Peptides that are derived from this epitope and that are capable of eliciting cytotoxic T cells that kill cells that express reverse transcriptase are provided. Test kits and meth-ods for identifying HIV-infected individuals using the peptides are also provided. The optimal antigenic side of the HIV-1 reverse transcriptase, which was identified using a murine antigen-specific CD8 + Class I MHC-molecule-restricted cytotoxic T-cell line, includes residues 203-219. This peptide was recognized by cytotoxic lymphocytes from HIV seropositive individuals, but not by cytotoxic lymphocytes from seronegative individuals, and, thus provide a means for diagnosing HIV infection. Test kits and methods for identifying HIV-infected individuals using the peptides are provided. Peptides that include this antigenic site provide a means for producing an immunologic response against a broad range of HIV, and, therefore may be useful for inclusion in an AIDS vaccine. Compositions that contain these peptides and that are formulated for parenteral administration are provided.

Title: Efficient nonmonotonic reasoning apparatus and methods
Inventor: CRAWFORD JAMES MELTON JR
IPC: G05B13/02
Filed: 1993-04-27
Granted: 1998-07-07
Abstract: The use of nonmonotonic or "common sense" reasoning has often been advocated to speed up reasoning systems. The difficulty has always been that nonmonotonic reasoning requires consistency checks, which are even more computationally intractable than the monotonic reasoning normally used in reasoning systems. Dislosed herein are methods and apparatus for making consistency checks tractable by performing them over a limited context using fast sufficient consistency checks. The results are approximate, but approximate results are expected in nonmonotinic reasoning. Include in the disclosure are techniques for selecting the limited context and making the fast sufficient consistency checks and a default reasoner which employs the techniques to check the consistency of a default conclusion with a limited context.
