Title: Slot coating die configuration
Inventor: MEISSNER HANS-JURGEN
IPC: B05C5/02
Filed: 1994-09-29
Abstract: ABSTRACT       A new and useful configuration for a slot coating die  is  provided,  which  is  designed  to  apply  a substantially streakless coating of a hot melt material (e.g., hot melt varnish) to a moving substrate such as a web of printed label stock.   The coating die is specially configured to  (i)  provide a substantially smooth, streakless coating of a hot melt material onto a moving substrate, and (ii) allow small particles in the hot melt material to be released from the coating die  and the web  so that the particles  should  not accumulate in the coating die or cause streaking of the coating.  The coating die has an upper lip, a lower lip, and a slot disposed between the upper and lower lips. The upper lip is undercut (or offset) relative to the lower lip, and has a front face which is configured to form (i) a wiping surface,  (ii) a release surface which extends beyond the wiping surface and curves away from the moving substrate, and (iii) a relief surface which extends from the slot to the wiping surface.   During operation of the slot coating die, hot melt material is extruded through the slot, and the configuration of the upper die member (i) guides the hot melt material in the direction of movement of the substrate and toward the wiping surface, (ii) gently wipes the hot melt material to a smooth, streakless state, and (iii) enables small particles in the hot melt material to be released from the slot coating die in a manner designed to avoid accumulation of particles in the coating die and/or streaking of the coating.

Patent CA-2134529-A1 (CA)
Title: Pipe joint with two tubular joint members
Inventor: OHMI TADAHIRO
IPC: F16L19/02
Filed: 1994-10-27
Abstract: A pair of tubular joint members each have a gasket holding annular protuberance on an abutting end face thereof. The protuberance has an inner peripheral surface continuous with the inner peripheral surface of the joint member, and a sealing face adapted to intimately contact an end face of of a gasket at a position radially outward from the inner peripheral surface thereof. The sealing face is most protuberant at a position radially outward from an inner edge thereof. When the most protuberant end of the sealing face comes into contact with the gasket end face, a clearance is formed between the portion of the sealing face radially inward from the protuberant end and the radially inward portion of the gasket end face. The clearance is eliminated by the deformation of the gasket when the pipe joint is tightened up.

Title: Method and an apparatus for adding a malodorant to a consumer gas
Inventor: SM RS ERIK
IPC: B01F23/10
Filed: 1992-06-16
Abstract: An arrangement for adding an odorant to a consumer gas which is distributed to a consumer site, in order to indicate to people in the vicinity of the risk of fire, explosion, poisoning, suffocation or some other danger, should consumer gas leak into the surrounding atmosphere. The odorant is dissolved in a condensed vehicle gas in a pressure vessel (3), to obtain a solution, master gas, which includes a liquid phase (6) and a gas phase (7). The consumer gas is diluted with an adapted quantity of the liquid phase of the master gas, which is vaporized prior to being mixed with the consumer gas. To this end, the arrangement includes means (18) for correcting the relationship between the two gas flows during the dilution process with respect to the increase in the concentration of odorant in the liquid phase (6) of the master gas that results from the decreasing relationship between the quantity of liquid gas and gas phase (7) in the pressure vessel. This provides for extremely accurate metering of the master gas. The invention also relates to a method of adding an odorant to a consumer gas.

Title: Liquid permeable, quilted film laminates
Inventor: ZELAZOSKI GREGORY A
IPC: B32B3/24
Filed: 1994-11-25
Abstract: Disclosed herein is a quilted film laminate wherein a film having a plurality of generally parallel slits is laminated to a substrate layer such as a fibrous nonwoven web.      Due to processing conditions, once the slit film layer and substrate layer have been laminated to one another, the composite is allowed to retract thereby giving the composite a puckered or quilted appearance with an undulating surface.      The undulating surface also causes the slits to form a plurality of openings which are generally perpendicular to the central plane of the film. In addition, due to the undulating nature of the surface of the film, the apertures so created reside in, above and below the central plane of the film layer. The composite so produced has a wide variety of uses not the least of which include a cover material or body side liner for personal care absorbent products. The process for producing the composite is also disclosed.

IPC: A61B18/14
Filed: 1993-02-18
Abstract: An electrosurgical tubular trocar system (10) has a hollow tube (13) substantially longer than its diameter. The tube (13) is shaped for insertion in a direction generally along its axis through tissue of a human or animal body. Distal and proximal ends (17 and 18) on the tube (13) enter and remain outside the tissue, respectively. A tip (19) on the distal end (17) punctures tissue of a human or animal. An insulating portion (20) of high dielectric material extends along the tube (13) between the distal and proximal ends (17 and 18). An electrode (14) on the insulating portion (20) extends from the proximal end (18) to the tip (19) to transmit radio frequency energy. A tip point (19) at an acute angle to the axis lessens the initial force necessary for entry of the tube (13). The return path (16) is a conductor (23) on the insulating portion (20) for bipolar cutting across a gap (25). An alternate system may have the return path (16) as a conductive pad (15) in contact with the tissue as a monopolar circuit. The tube (13) may be in fluid communication for flow.

Title: Pertussis toxin used as a carrier protein with non-charged saccharides in conjugate vaccines
Inventor: SCHNEERSON RACHEL
IPC: A61K39/116
Filed: 1993-08-17
Abstract: A medically important and useful conjugate comprising pertussis toxin (PT), or another antigen having similar physico-chemical properties, as the carrier protein component, coupled to a neutral or non-charged saccharide, particularly, the capsular polysaccharide of Streptococcus pneumoniae type 14 (Pn14), for use as an effective, non-toxic, and highly immunogenic vaccine is described. The invention is directed to a novel synthetic scheme wherein PT and like proteins, and a derivative of Pn14, and the like, were coupled at acidic pH via carbodiimide-mediated condensation to produce an immunogenic conjugate. The coupling procedure yielded a Pn14-PT conjugate in which the PT component was rendered non-toxic and both the PT and Pn14 components were immunogenic, as determined by the production of protective levels of both type-specific and neutralizing antibodies in mammals. The Pn14-PT conjugate was used as an immunogen at levels estimated to be protective in humans and stands to provide an effective, safe, and potent human vaccine.

Title: Apparatus and method for controlling the loop bandwidth of a phase locked loop
Inventor: GILLIG STEVEN FREDERICK
IPC: H03L7/183
Filed: 1994-11-21
Abstract: In a phase locked loop (PLL) (308), an edge proximity dectector (302) identifies a phase error, indicative of a difference between a phase of a reference frequency signal (115) and a phase of an output frequency signal (116 or 117), as either desirable or undesirable. When the phase error is identified as desirable, a counter (301) determines a rate of change of the phase error over a first predetermined time period (412) to provide an indication of frequency error (306) between the frequency of the reference frequency signal (206) and the frequency of the output frequency signal (116 or 117); and a loop bandwidth adjuster (310) controls a transition between a first and a second loop bandwidth state of the PLL (308) responsive to the indication of the frequency error (306). When the phase error is identified as undesirable, the PLL (308) operates in the second loop bandwidth state. The present invention advantageously provides an accurate determination of when to vary the loop bandwidth of the PLL (308).
