Abstract: A device for hyperthermia treatment in a body cavity or duct which has a narrow access pathway includes an elongate distal section for insertion into the body cavity comprising a centrally-located heat-releasing element enclosed by an elastic enclosure. The heat-releasing element is either surrounded by an elongate housing or is shaped to form a housing. An axially opening inlet passage opens to the proximal part of the housing to supply a heat-transmitting fluid to the housing. The housing has an outlet port to allow fluid to flow from the housing to fill and expand the elastic enclosure to exert pressure on the walls of the body cavity and an inlet port which allows fluid to return into the housing, thus permitting circulation of the fluid during treatment which results in uniform heating of the fluid. The heat-releasing element is formed of an inherently heat self-regulating type material and is either a semi-conductor material of PTC-type having a Curie temperature or Trip point, or a ferromagnetic material having a Curie point in combination with a supply of energy based on magnetic induction.

Abstract: A continuous process for applying a coating to both sides of a paper web in which the web is fed at a speed of at least 400 meters per minute through the nip formed between a rotating applicator roll and an elastically yielding blade. A coating composition is fed into the sumps formed on each side of the web at the nip at a rate such that the amount of coating material applied to the web, calculated as the total of both sides of the web, exceeds 14 grams per square meter. The viscosity of the coating composition is maintained at 400 to 2000 centipoises and the web is withdrawn from the nip so that it is bent away from the applicator roll over the edge of the blade at an angle of between 8.degree. and 12.degree. to the tangient to the roll at the nip, thus reducing or eliminating the formation of mist downstream of the nip.
