Abstract:
A door handle assembly of a household refrigerator having a stiffener member with an elongated body made of rigid metal in the shape of an upwardly open channel with spaced apart legs including a first section offset form a second section to act as the gripping section and having spaced apart fastener receiving apertures. The first section has a molded soft elastomeric covering on the outside with apertures in alignment with the apertures in the stiffener member. A first decorative trim member having an outer and inner side with a contour to receive the legs of the channel of the first section of the stiffener member and including side walls overlapping the upper edge of the legs and elastomeric covering. The trim member has an open upwardly facing recess area in the outer side with apertures in alignment with the apertures in the stiffener member. There is an enlarged metal plate dimensioned to be nested in the recess area of the decorative trim member and having threaded fastener receiving apertures in alignment with the apertures in the decorative trim member and stiffener member. A second decorative trim member with an upwardly open channel surrounds the base and both legs of the channel of the second section and has one end secured to the decorative trim covering the first section and the other end secured to a trim end cap. A downwardly open channel shaped member is secured to the upwardly open channel of the second decorative trim member. Threaded fasteners pass through the apertures and threadedly engage the fastener receiving aperture in the elongated metal plate to rigidly assemble the components together as a subassembly for installation on a refrigerator door.
Abstract:
A tubular printing blanket for a blanket cylinder in an offset printing press comprises a cylindrical sleeve, a compressible layer over the sleeve, and an inextensible layer over the compressible layer. The cylindrical sleeve is movable telescopically over a blanket cylinder. The compressible layer comprises a first seamless tubular body of elastomeric material containing compressible microspheres. The inextensible layer comprises a second seamless tubular body of elastomeric material containing a tubular sublayer of circumferentially inextensible material. A seamless tubular printing layer over the inextensible layer has a continuous, gapless cylindrical printing surface. Methods of manufacturing the tubular printing blanket are also disclosed.
Abstract:
A printing sleeve comprises a cylindrical tube of polymeric material reinforced with overlapping, closely touching windings of fibrous reinforcing material with at least one winding extending in each direction. The windings are wound in a helical pattern at a wind angle of about 40.degree..
Abstract:
A compressible roller especially useful in high speed printing systems consists of a rigid core and a compressible cover. The cover consists of a first relatively thick layer of compressible foam containing entrapped gas which is bonded to the core; an elastomeric seal, which prevents the entrapped gas from leaving the foam, bonded to the foam; and an outer print layer of a compatible elastomer bonded to the seal.
Abstract:
A new dot enzyme immunoassay (EIA) with a conserved portion of the envelope protein of the human immunodeficiency virus (HIV) as antigen has been designed for use in areas with few laboratory facilities and by personnel with little laboratory experience. Sera were tested in 263 subjects who had AIDS or AIDS-related complex or were at -risk or not-at-risk of AIDS from the USA, Africa, and Asia/Oceania. The dot EIA was 100% sensitive in the American subjects, and there were only 2 false negatives in the others, both of which were negative by commerical EIA. The test is simple to perform, economical, rapid (30 min), and stable.
Abstract:
A fluid transfer roller for use in offset printing for picking up a film of water and transferring it to a printing plate consists of a rigid core with an outer layer of foamed-in-place, partially open-celled foam.

Abstract:
A dielectric roller for a corona treatment system consists of a self-supporting tubular body of a dielectric material having a conductive layer bonded on its inner wall and a pair of end plugs with hubs closing the ends of the body. At least one of the end plugs is of conductive material and makes electrical contact with the conductive layer so that the roller can be grounded.
