Abstract: An apparatus unit for the fractional distillation and rectification of liquid mixtures includes a plurality of horizontal superimposed tubular main sections interconnected in series by a plurality of tubular connecting sections, e.g. U-shaped, to define an elongated space along which liquids and vapors flow. Intimate contact between liquids and vapors and efficient heat and mass transfer are provided by a stirrer rotating within the main section about horizontal axes and magnetically driven from the outside. Suitable inlet and outlet ports and heating and cooling devices are provided. An arrangement for joining the adjacent sections without the use of flanges or threaded portions is provided. A number of such units are preferably associated to form a modular apparatus, the individual units being operatively connected as desired to provide series, parallel or mixed flow of the fluids.

Abstract: Apparatus is described for the treatment of edema, comprising a substantially flat inflatable band divided into a plurality of internal inflatable cells extending along one dimension of the band, and wrappable about the body part to be treated to form a sleeve with the inflatable cells extending annularly around the sleeve, the inflatable cells being in partially overlapping relationship widthwise of the band. The band is made of three strips of resilient sheet material bonded to each other along spaced bond lines to define the partially overlapping inflatable cells.
