Abstract: An improved method of pulp or pressure molding a multilayer container is disclosed wherein the inner layer consists of fused water dispersible polyolefin fibers whereas the outer layer consists of a mixture of cellulosic fibers bonded together by fused water dispersible polyolefin fibers. The containers are useful because the polyolefin layer is resistant to the passage of liquid such as lubricating oils and semi-solids such as greases while the mixed layer of cellulosic fibers and the polyolefin fiber supplies sufficient strength to permit the stacking of the containers when filled.

Abstract: Method is disclosed for preparing a honeycomb insulation structure having its cells partially filled with a low density foam and a high density integral skin completely covering one edge of the honeycomb. Method comprises placing one edge of a honeycomb in an inert material; introducing a foamable or foaming substance into the cells and allowing it to rise from the surface of the inert material until it overflows slightly. The overflowing foam comes into contact with a pressure platen just above the honeycomb thereby forming the high density integral skin. The level of the material in the cell determines the thickness of the void on one edge. Structure has utility in cryogenic storage.

Abstract: A system for calibrating the flow rate of a pump, and especially designed for a pump which is normally used in a system to blend highly vaporous and odorous fluids, in which the blending fluid discharged from the pump is diverted from its normal flow stream into a closed calibration system which has a sight glass for receiving the fluid discharged by the pump. After a predetermined number of cycles by the pump, the amount of fluid within the sight glass is determined and then the calibration system is purged by a displacement gas so that the offensive material is returned back to its original source to be reused in its normal fashion.
