Filed: 1993-05-13
Abstract: Abstract of the Disclosure Process for the Production of a Multicolored Image,  and Photosensitive Material for Carrying out this Process The invention relates to a photosensitive material for the production of color proofing films for multicolor printing comprising:   A)  a transparent, flexible film support, B)  a photopolymerizable layer containing:     B1)  a polymeric binder, B2)  a free radical-polymerizable compound, B3)  a compound which is capable of initiating the polymerization of (B2) on exposure to actinic light, and B4)  a dye or colored pigment in a primary color of multicolor printing, and C)  a thermoplastic adhesive layer on the photosen-sitive layer, which contains at least about 1.5% by weight of a water-soluble, colorless, low-molecular-weight salt whose aqueous solution is not highly acidic.            The material is processed by lamination onto an image-receiving material, exposure and peeling apart of the film support and the image-receiving material, the unexposed areas of the layer and the adhesive layer remaining on the image-receiving material.  The addition of the salt to the adhesive layer substantially reduces the adhesion between this layer and the exposed areas of the photopolymerizable layer.

Title: Lubricious hydrophilic coating, resistant to wet abrasion
Inventor: WHITBOURNE RICHARD J
IPC: A61L27/34
Filed: 1991-02-05
Abstract: The lubricious hydrophilic coatings of the invention are significantly more lubricious when wet than when dry, are adherent to a variety of substrates, and are resistant to removal by wet abrasion. In one embodiment, the coatings include a hydrophilic polyolefin such as polyvinyl-pyrrolidone and a water-insoluble stabilizing polymer such as a cellulose ester. The coatings may also include an adherent polymer and a plasticizing agent. The coating may be applied by preparing a solution of the stabilizing polymer and a solution of the hydrophilic polyolefin, and coating the substrate first in one then the other. Alternatively, both the stabilizing and hydrophilic polymers may be dissolved in a single solvent system and applied to the substrate in a single step. In another embodiment, only a solution of a hydrophilic polyolefin is applied directly to the substrate. In this embodiment, the solution of the hydrophilic polyolefin includes a cosolvent which acts as a solvent for both the hydrophilic polyolefin and the substrate. The coatings of the invention may be applied to biomedical devices and implants such as catheters, condoms, and nasogastric and endotracheal tubes.

Abstract: The invention relates to a process for the con-tinuous determination of the dust content of flowing media with the isokinetic flow sampling with the separa-tion of the dust or aerosols by cake filtration on a fil-ter and the measurement of the pressure drop at the fil-ter to determine its degree of clogging. To this end the time cycle of the quantity of dust separated on the fil-ter is determined by the measurement of the pressure loss at the filter of an isokinetically operating sampling system. To find the dust load, this quantity of dust is related to the partial quantity of gas extracted iso-kinetically during the period concerned.

Patent CA-2133925-A1 (CA)
Inventor: VARDEN ARNOLD
IPC: F16K5/20
Filed: 1994-10-20
Abstract: This invention relates to ball valves. One problem with conventional ball valves is that opening and closing the valve causes the valve seal to scrape across the valve seat. This reduces the life of the seal. This scraping problem can be eliminated by retracting the seal from the seat before turning the valve.      Tn this invention, the ball valve has two co-axial handle assemblies. The outer, lever, assembly turns the valve closure member within its housing. The inner, handwheel, assembly is used independently to retract or extend the valve seal from or to the valve seat. The retraction or extension is achieved by use of a jack-screw shaft which pushes the seal in and out. The jack screw shaft is driven by a series of gears - a first bevel gear, a ring gear, and a second bevel gear - driven by the inner handle assembly. The ball valve is also provided with an inspection port. This part permits inspection, repair, or replacement of the valve seal while the valve is in use in its open position.
