Title: Stabilizer for a floating platen
Inventor: MERRIMAN RICHARD A JR
IPC: B41J11/20
Filed: 1991-10-21
Abstract: An apparatus for use with a print head which is used in conjunction with a floating platen.  The print head in mounted on a carriage which has a forms compensation member secured to it to contact the top surface of a document to be printed upon.  The forms compensation member causes the print surface of the platen to tilt somewhat causing ink smears or uneven printing by the print head.  A stabilizer is used to offset the tilting caused by the forms compensation member to thereby maintain the printing surface of the platen in parallel relationship with print face of the print head, which in the embodiment described, is a wire matrix printer.  The stabilizer includes first and second leaf springs which are secured to the platen and cooperate with a channel in which the platen is mounted.

Title: Assembly and method for cleaning a printing roll
Inventor: ROBERTS DONALD L
IPC: B41F35/00
Filed: 1991-10-28
Abstract: ABSTRACT      A printing press arrangement includes printing units, a dryer and chill rolls used to cool the hot ink and printed web upon exit from the dryer.  During operation, condensed ink solvent builds up on the surface of the chill rolls.  This build up of condensate is removed by a wiper assembly that is mounted to the printing press.  The wiper assembly includes a cloth wrapped sponge-wiper that engages and wipes the exterior surface of the chill roll as the chill roll rotates.  The wiper assembly further includes a plurality of nozzles that spray a liquid mist onto the exterior surface of the chill roll.  The liquid mist softens the condensate deposits allowing them to be wiped from the exterior surface of the chill roll by the wiper.

Title: Method and apparatus for high performance separation by sample displacement chromatography
Inventor: HODGES ROBERT S
IPC: C07K1/16
Filed: 1992-01-09
Abstract: A high performance liquid chromatography method.  The method employs an HPLC apparatus composed of a series of chromatography segments connected end-to-end by valved connectors which are operable to communicate adjacent segments, or to divert fluid from a joined segment to an elution collection site.

Title: High purity stratified tissue and method of making same
Inventor: JANDA BRUCE
IPC: A47K10/16
Filed: 1992-01-15
Abstract: A Foam-Formed nonlaminated stratified paper tissue and method of making the same includes a first zone of foam-formed paper tissue formed from a furnish which is relatively rich in hardwood fiber. A second zone of foam-formed paper tissue is formed from a furnish which is relatively rich in softwood fiber. The second zone is formed unitary and entangled with the first zone to form a nonlaminated stratified paper tissue. A high softness integument is defined adjacent to an outer surface of the first zone and a substratum is defined adjacent to a surface of the second zone spaced away from the integument. The integument on the outer surface of the first zone includes an enriched region wherein the hardwood fiber content is greater than that obtainable in the corresponding region of a tissue obtained from furnishes having the same compositions under the same conditions but employing water-forming instead of foam-forming. The substratum on the surface of the second zone includes a region enriched in softwood fiber. The enriched region of substantially pure hardwood fiber provides an extremely soft and smooth surface as detected by human somatic sensibility.

Inventor: KRISHNAMURTHY BALACHANDER
IPC: G06F9/44
Filed: 1992-04-09
Abstract: Abstract of the Disclosure An extensible event-action system which permits a user of a computer system to specify actions to be performed in response to combinations of user-defined and/or system events. A user-defined event takes place when a process sends an announce message to a daemon process in the system. The system de-fined events include clock events, file system events, machine events, process events, user events, and terminal events. The daemon process maintains ta-bles of event definitions and event-action specifications which specify a com-bination of events and an action. The daemon process further keeps track of the occurrence of system- and user-defined events and performs the action specified in an event-action specification when the events specified therein have occurred. The actions may include commands which affect the event definition and event-action specification tables. Events are defined in terms of objects and attributes. An event has occurred when an attribute of an instance of an object is set to a value which is specified for the attribute. The attributes may be predefined or may be user-defined. Values are set in predefined attributes by system defined events and in user-defined attributes by the announce message.

Title: Multiple hepatitis b virus surface proteins which form particles
Inventor: KNISKERN PETER J
IPC: C07K14/10
Filed: 1992-04-29
Abstract: TITLE OF THE INVENTION MULTIPLE HEPATITIS B VIRUS SURFACE PROTEINS WHICH FORM PARTICLES            ABSTRACT OF THE INVENTION     In order to produce a mixture hepatitis B virus (HBV) surface proteins in the form of particles, DNA encoding two or more HBV proteins was expressed by a single recombinant yeast.  In order to form particles with substantially reduced carbohydrate, such DNA encoding two or more HBV proteins is expressed in a single recombinant yeast host which is deficient in its ability to glycosylate proteins.  These B V proteins display the antigenic sites genetically encoded by the S domain (including the preS domain) of the HBV virion envelope open reading frame and 43/JWW24                - i -                 18350 when expressed in a yeast deficient for its ability to glycosylate, contain substantially reduced levels of entrapped carbohydrate when compared with HBsAg particles produced in yeast cells "wild-type" for glycosylation.  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 including antigenic variants in the immunodominant epitopes of the surface protein and also are useful as antigens and immunogens for development of diagnostic tests for such diseases or infections.

Title: Process for preparing n-alkyl polyhydroxy amines in amine and amine/water solvents and fatty acid amides therefrom
Inventor: SHUMATE ROBERT E
IPC: C07C231/02
Filed: 1991-09-25
Abstract: Amines such as methyl amine are reacted with materials such as reducing sugars in amine or amine/water solvents to prepare N-alkyl polyhydroxy amines. Accordingly, glucose is reacted with methyl amine and the resulting adduct is hydrogenated to yield N-methylglucamine. The N-alkyl polyhydroxy amines can be subsequently reacted with fatty esters to provide polyhydroxy fatty acid amides useful as detersive surfactants. Thus, detersive surfactants are available from non-petrochemical precursors such as sugars and sugar sources such as corn syrup, and fatty acid esters derivable from various fats and oils.
