Abstract: 1292874 Surgical dressings W SEUSS 6 Jan 1970 [14 Jan 1969] 553/70 Heading A5R [Also in Division C3] A flexible article of foam material having a form adopting it to be applied to part of a living body comprises a synthetic plastics material and displays an electrical polarisation of permanent orientation for producing a therapeutic effect upon the body part. The article may be prepared by allowing the synthetic plastics material plus any non-plastics material additives to cure from the liquid state, the plastics material and/or at least one of the additives, if any, being or having been subjected to a unidirectional electric field. The subjection to the unidirectional field occurs suitably whilst the synthetic plastics material is curing. In general direct-current voltages of about 2000 volts are need for polarisation. The foam is preferably a polyurethane, urea or phenolic foam and the polarisation thereof suitably takes place in the casting mould which is formed as an electrical capacitor. Polarisation of the finished product is promoted if some or all components of the foam material are already polarised when brought together. One or more of the additives may be pharmacologically active. The foam material, in the form of coverings, bindings or bandages, may be placed upon the body, a direct influence upon the tissue in the form of a relaxation of muscle structure, softening of hardened tissues and pain alleviation being observed.

Title: A method of improving the bonding properties of polyethylene type plastics
IPC: B29C59/08
Filed: 1950-01-10
Abstract: The bonding properties of the surface of synthetic resins of the polyethylene-resin type, more particularly for printing inks and adhesives, are improved by exposing the surface to a raised temperature which is not high enough to impair the stability of the resinous material, while the material adjoining this superficial layer is maintained at a temperature below the minimum temperature that is effective for activating the surface, thereby causing a reorientation of the polymer molecules in the surface layer which is slowly reversible on cooling.  Synthetic resins specified are polymers and copolymers of ethylene and its homologues.  The surface of the film, sheet, or other article is preferably heated to a temperature from 60 DEG  C. up to and above the melting point of the resin, while the remainder of the body is maintained at a temperature below 60 DEG  C. the surface layer which is thus treated preferably being from 5 to 10 mm. thick.  The heat treatment may be effected by means of a gas flame, a heating element, hot air, or oven heating, and the surface may be printed upon either before or after the heat-treatment, a suitable printing ink being one constituted by polyvinyl chloride/acetate plasticized with octyl phthalate, titanium dioxide, medium boiling aromatic hydrocarbons, and low and medium boiling ketones.
