Title: Media roller high friction surfacing system
Inventor: OLSON ALLAN G
IPC: B65H27/00
Filed: 1995-11-13
Abstract: A method and apparatus is achieved for creating or restoring a high friction surface to a drive roller (52). Abrasive pads (12) define a scrubbing surface for acting upon a media roller's surface (54-58). As the roller's surface is scrubbed, creping occurs which increases the surface's coefficient of friction be-tween the roller and media sheet ("COFB(?)"). In one embodiment, the creping apparatus is formed by a pair of plates (16, 18) hinged along one edge (30) and open along an op-posite edge (28). A spring (19) is positioned between the plates bias-ing the plates apart at the open end. One or more abrasive pads are attached to the outer surface of one plate (18). To create or restore a high friction surface, the apparatus (10) is positioned adjacent to the roller (52). By approximately defining the force applied between the roller (52) and abrasive pads (12) and by using an abrasive pad of known grit, initially surface contaminants, if any, are scrubbed from the roller surface (54-58).

Abstract: The growth of bacteria in latex and emulsifiers is an age old problem. Chemical bactericides are of ten added to latex and emulsifiers to control the growth of bacteria therein. This invention discloses a technique for providing emulsifiers and latex with resistance to bacterial growth. It is based upon the discovery that ions of a metal from Group Ib of the Periodic Chart, such as copper, silver or gold, will provide emulsifiers and latex with resistance to bacterial growth The subject invention more specifically discloses an emulsifier system which consists essentially of (1) an emulsifier and (2) ions of a metal from Group Ib of the Periodic Chart. In most cases, the metal ions will be present in an amount which is within the range of about 1 ppm to about 50 ppm. As a general rule, copper ions or silver ions are preferred. Latices having resistance to bacterial growth can be made by simply utilizing such Group Ib metal-containing emulsifiers in the synthesis thereof. The present invention accordingly further reveals a method for producing a latex having resistance to bacterial growth which comprises polymerizing at least one monomer in an aqueous emulsion which is prepared utilizing an emulsifier system which is comprised of (1) an emulsifier and (2) ions of a metal from Group Ib of the Periodic Chart.

Title: Microgels for use in medical diagnosis and methods of making and using same
Inventor: WATERHOUSE PAUL
IPC: G01N27/447
Filed: 1995-10-31
Abstract: An electrophoresis microgel is formed in a gel holder. The gel holder comprises a top substrate, a bottom substrate and a spacer disposed between the top substrate and the bottom substrate. The spacer establishes a separation of from 25 to 250 microns between the top substrate and the bottom substrate. A gel compartment is formed by partially sealing the top substrate to the bottom substrate, while leaving an opening for the introduction of unpolymerized gel. The gel compartment is then filled with an unpolymerized gel, which is polymerized in the gel compartment. Electrodes may be printed on the substrates, may be contacted to an exposed edge of gel, or may be applied through windows cut into one of the substrates. One type of gel holder makes use of graded beads having a diameter of 25 to 250 microns slurried in an adhesive such as an acrylate adhesive as the spacer. The slurry is printed onto the surface of one or both substrates to form a spacer of the desired shape, and then hardened using heat or light. If desired, the spacer can establish lanes within the gel.

Title: Heat sink for contact stems of a vacuum interrupter and a vacuum interrupter therewith
Inventor: BENKE JAMES J
IPC: H01H1/58
Filed: 1997-10-10
Abstract: Heat sinks are placed on the contact stems of a vacuum interrupter between the vacuum bottle and junctions with the terminal conductors to lower the temperature of these junctions. The heat sinks are formed by a stack of thin laminations having central openings with inwardly directed tabs which bite into and secure the laminations to the stems. The laminations have aligned slots forming axial passages for cooling air. Preferably, the slots are enclosed to eliminate sharp peripheral edges to reduce the potential for flash over. In one embodiment, the slots are not formed by removing material but by bending it out of the plane of the lamination to maximize heat radiating surface area and to generate turbulent cooling air flow for increased cooling efficiency. An axially extending peripheral lip can provide axial spacing between laminations.

Filed: 1997-10-14
Abstract: In a thermal printer in which ink is transferred from a single-use thermal print ribbon to a substrate such as packaging material by energising selected print elements of a thermal print head (22), a first print run is executed by energising only a group of print elements in registry with one half of the ribbon width so that ink is depleted only from one half of the ribbon, and a second print run is executed by energising the same group of elements using the same ribbon but with the ribbon supply and take-up spools interchanged in order that ink is depleted only from the other half of the ribbon. This allows printing on comparatively narrow printing areas using ribbon which is at least twice the width of the printed area without undue ribbon wastage and with reduced ribbon breakage frequency compared to the breakage frequency with a ribbon of a width nearer to the width of the printed area.
