A process is provided for making frost resistant cement products having improved 28 day compressive strengths wherein a gas is included in the product by substantially uniformly dispersing hollow gas filled synthetic polymeric spheres in the cement mixture prior to setting thereof. The invention also provides a frost resistant cement product having from about 0.01 to about 0.1% by weight based on ...

In a vertical, form-fill-seal, wrapping machine, downward flow of charges of product, from a charge dispenser 50 to the wrapper tube 21, is assisted by utilizing the Coanda effect to establish a pulsed product- entraining flow of gas in a nozzle 23 in the pathway which leads from the weigher to the wrapper tube.

The invention provides a novel and improved method for the preparation of a cellular foamed body of a vinyl chloride-based resin having a very fine and uniform cellular structure with high productivity in a continuous process. According to the inventive method, a vinyl chloride-based resin is admixed with a nucleating agent and a foam conditioning resin which is a specified acrylic resin or a styr...

A polymer granulate whose particles consist of a core component and a coating component can be prepared by mixing a granular polymer with a pulverulent coating agent. The core component is made of a water-soluble polymer, in particular a polyvinyl alcohol. The coating component is a water-soluble or water-insoluble substance which is applied to the water-moistened particles of the core component. ...
