Abstract: There is disclosed a hand-held labeler for printing and applying labels and for printing tags. The labeler has a keyboard, a display, a scanner, and a battery-containing handle. The labeler is user-friendly and compact. The labeler can be easily loaded with label and tag webs of different widths. The labeler has a discharge chute for the carrier web which can be slid to a position outside the labeler for easy cleaning.

Abstract: The machine for manufacturing vulcanized-rubber tubes has a pair of heads arranged oppositely with respect to mandrels which rotate two or more tubular cores, supported by supporting elements with fixed rollers on a supporting frame. The tubular cores are contained in a thermally insulated box-like container, wrapped in the tubes to be vulcanized and unloaded by transfer means. The container has heads for supplying electrical power to the cores. Devices are provided for removing the cores from the container. The machine also has a carriage which can move along guides which are parallel to the cores, and a mechanism for wrapping the cores simultaneously with spirals of the materials to be used to manufacture tubes.

Abstract: A process for the production of structural and semi-structural composites formed by compressing planar layers of nonwoven preform materials formed from aqueous blends of reinforcing fibers and thin thermoplastic fluoropolymer flake. The flakes have an irregular periphery with microfibrils extending therefrom, having a Canadian Standard Freeness of from 800 to 883. The planar layers which are unconstrained in the in-plane direction are preconsolidated by heating the layer to above the melting point of the fluoropolymer, the applying pressure normal to the plane of the layer causing the fluoropolymer to flow thus orienting the fibers in the plane of the layer. The composites are useful in applications which require higher strength and/or modulus, and where chemical and/or heat resistance is needed, as in chemical processing.
