The preparation of monolayer blown nylon films on equipment conventionally used in the manufacture of blown polyethylene film is facilitated by the intimate admixture of a minor proportion by weight of a random ethylene/ethylenically unsaturated carboxylic acid copolymer into the nylon resin composition from which said blown nylon film is to be manufactured.

Resilient foam particles and moldings are obtained employing a lightly crosslinked polymer such as a styrene polymer with volatile fluid foaming agent that has low permeability through the polymer. Multiple expansion will permit low density particles for molding.

A control process for a rotary pump which is immersed in a fluid produced by a well involves the use of a rotary pump driven by a variable speed motor and comprises the steps of acting upon the rotational speed of the motor according to a pressure difference which exists between the pressure of the fluid measured in the proximity of the pump and the production pressure of the well. The production ...

The present invention relates to generating a hot gas consisting primarily of CO and H2 from a carbonaceous starting material which, in pulverulent form, together with oxidizing agent and optionally also a slag-former, is introduced into a gasification chamber, where it is combusted and partially gasified.
