Abstract: A process for improving the thermal insulation properties of articles such as jackets or slabs made of open cells polymeric foam material is disclosed. A viscous solution is prepared, capable of coating the inner walls of the passages interconnecting the cells. Particles of a size less than the minimum diametrical length of the passages are mixed with the solution. The article is soaked with the mixed solution, squeezed and dried, so that the particles dispersed within the passages partly block the flow of air between adjacent cells.

Abstract: A hydraulic axial pump/motor comprises a plurality of revolving as well as reciprocating pistons, operatively associated with a stationary port plate. The port plate comprises at least a first, elongated, arcuate suction port and at least a second elongated, arcuate discharge port, divided by a bringing portion extending between the downstream side of the suction port and the upstream side of the discharge port. A tortuous passage of a non-uniform cross-section is formed in the bridging portion, allowing the by-passing of the fluid first in a direction towards the downstream side of the suction port and then towards and into the upstream side of the discharge port.

Abstract: A method of insulating a heated surface comprising enveloping the surface by a first layer of a heat insulating material having a high thermal resistivity such as Mineral Wool, and enveloping the first layer by a second layer of a material having a lower thermal resistivity, such as Polyurethane.
