Abstract: A container for thermal conditioning of a fluid under pressure, use of the container for thermally conditioning a fluid under pressure, a chemical reactor including the container and a polymerization process using the reactor, and a method of producing the container and the reactor. The container is bounded over at least part of its surface facing the outside by at least one external plate and facing the inside by at least one internal plate, the external plate being thicker than the internal plate, the external plate and the internal plate being joined together in places to define a space between joints for circulation of a heat-transfer fluid and the container including a mechanism to adjust the pressure of the heat-transfer fluid to that of the fluid under pressure.

Abstract: A method for drying a wet polymer including a drying carried out in a dryer containing at least heating element inside which a heat-transfer fluid flows, the heat-transfer fluid being low-pressure steam.

Abstract: The latex is treated by passage through a heat exchanger consisting of a closed chamber 1 divided into two distinct superposed parts, the unobstructed upper part 3 being placed under reduced pressure and communicating with a plant for recovery of the residual monomer or monomers, and the lower part 4 being equipped with a partitioning 9 bounding two separate extended and adjoining circuits 10 and 11, one of the circuits 10 being traversed by the latex to be treated and being maintained in communication, via its top and over its entire path, with the upper part 3 of the chamber, and the other circuit 11, isolated from the upper part 3 of the chamber, being traversed by a heat-transfer fluid maintained at a temperature of 40 to 100.degree. C.Preferably, the two circuits 10 and 11 are bounded by a partitioning 9 arranged in the form of a double spiral.

Abstract: A single tire chain adapted to be placed on an automobile tire and be anchored at its ends in front of and through an opening in the wheel.

Abstract: A portable apparatus for irrigation of the intestines and colon wherein an undulating stream of warm water is injected by an enema tip vertically reciprocating in and out of the lower end of the rectum in timed relation allowing for simultaneous intermittent discharge of waste products therefrom.
