Abstract: The present invention relates to a method for separation of a polymer from a polymer solution or dispersion, wherein (i) a solution or dispersion of a polymer in an organic solvent is atomized by being brought into contact with water vapor in an atomizer container; (ii) the mixture obtained in the atomizer container is routed into a polymer degasification container and flows through same, wherein the organic solvent present in the polymer particles is driven at least partially out of the polymer particles due to the thermal contact between the polymer particles and the water vapor and transitions into the gas phase (iii) the mixture exiting from the polymer degasification container is routed into a phase separator (1) and the organic solvent present in the gas phase is separated from the polymer particles and the condensed water vapor; and (iv) the polymer particles and the condensed water vapor are routed into a phase separator (2) in order to separate the polymer particles from the condensed water vapor.

Abstract: A hopper dispenses cement or mortar into the space between side by side paving bricks. The hopper is a self supporting container. The container has opposing container sides converging downwardly to an elongated opening. This elongated opening extends for most of the length of the container. The opening has just below it a spaced pair of thin parallel guides for guiding the cement or mortar into the space between the paving bricks.

Abstract: A combination joint rake and jointer tool for raking and smoothing mortar in the joints of brickwork is described herein. The tool is used for removing excess mortar and for smoothing the remaining mortar. The tool has an elongated tool body having a medial portion forming a handle therefor. A sled bar for smoothing the mortar is attached at both ends of the handle. The sled bar has curved end portions extending from the handle and a runner portion therebetween. Further, a rake and carriage assembly attached at one end of the enlongated tool body includes, in turn, a rake and carriage support attached to one end of the elongated tool body; a pair of wheels attached to the support with one of the pair of wheels on each side of the support for supporting the tool body and sled bar means during travel across the face of the brickwork. An adjustable rake is attached to and extends from the support, which rake is adjustable to a predetermined depth in to the joints.
