Abstract:
A carrier strip for holding labels to a support, such as the edge of a shelf, includes a rear wall which can be attached to the support and a transparent front wall which is connected to the rear wall so as to form a pocket between the walls. The carrier strip is made by extruding a plastic composition at relatively high pressure through a die which imcompletely smooths the surface irregularities resulting from the relatively high extrusion pressure. This disrupts the longitudinal striations or dielines which are characteristic of extruded members and which might otherwise cause undesirable reflections when a bar code reader is used to read a bar code printed on a label in the pocket.
Abstract:
A pipe coupling for driven-in pipes or the like includes a first pipe having a male coupling end, a first annular supporting element connected about the male coupling end, and a second pipe having a female coupling end adapted to receive the male coupling end. The female coupling end has a second annular supporting element connected to the exterior of the female coupling end.
Abstract:
Use of cellulose fibers of natural origin as an admixture to polyvinyl chloride is disclosed. Structurally modifying a polyvinyl article by admixing cellulose fibers limits heat shrinkage thereof and results in improved surface characteristics and/or mechanical characteristics. A polyvinyl article is provided which is comprised of polyvinyl chloride and from 1 to 40 wt. %, preferably from 3 to 20 wt. %, cellulose fibers having a fiber thickness ranging from a finite thickness to about 40 .mu.m and a fiber length ranging from twice the fiber thickness to about 400 .mu.m, preferably from about 80 .mu.m to about 400 .mu.m.
Abstract:
The invention relates to the use of a fraction of hardened particles of an elastomer material of limited particle sizes between 0.1 and 1 mm, preferably between 0.3 and 0.7 mm. The order of magnitude of the admixture to every 100 parts of unhardened elastomer material lies at 5 to 60 parts, preferably 20 to 40 parts. The admixture of the particles to the elastomer material is effected before the elastomer material hardens and is done to produce a defined, non-smooth surface in end products made of elastomers.
Abstract:
A heatable plastic hose for transporting fluids, particularly liquids, includes a tubular hose having a cross-sectional center point and a hose wall which defines, along the inner surface thereof, a longitudinal cavity having a cross-sectional center point which is laterally offset from the cross-sectional center point of the tubular hose, the tubular hose having, in cross-section, a first wall portion and a second wall portion, the first wall portion being thicker than the second wall portion; and a heating conductor wire which is longitudinally coextensive with the tubular hose and is embedded in the first wall portion.
