As is known, wound dressings are needed for burns, extensive skin wounds, skin defects or the like. Wounds of this type are susceptible to contamination by microorganisms, including fungi, and can then develop into septic wounds which are slow to heal and require a special wound dressing and wound treatment. The aim is to provide a wound dressing which is permeable to oxygen and fluids and should ...

An improved actuator assembly for an electromagnetically-actuated spring-loaded positioning system in displacement machines, such as for lifting valves in internal combustion engines. The positioning mechanism has a spring system and two electrically-operated, opposed actuating solenoids, by means of which the actuator may be moved between, and held at, two discrete, mutually-opposite operating po...

A lubrication system for internal combustion engines including an electrically operated oil pump, a conduit, an electrical time-delay relay, a one-way valve and a pump bypass. Another conduit and electrical time-delay relay may be used with turbocharged engines. The lubrication system pressurizes engine oil when the mechanical oil pump is not fully operational. In a preferred embodiment, the lubri...

A process for producing a thermoplastic polyester resin foam comprising melting a thermoplastic polyester resin, mixing the molten resin with a blowing agent and extruding the mixture into a low-pressure zone to carry out expansion molding, characterized in that a compound having two or more acid anhydride groups per molecule, optionally together with a compound of a metal of Group I, II or III el...

Closed-cell polyisocyanate-based foams are prepared using a blowing agent mixture containing an organic compound having a boiling point in excess of 65 DEG C in conjunction with another organic compound having a boiling point below 40 DEG C. This invention provides for the use of high-boiling blowing agents which previously were not considered suitable for preparing closed-cell foam due to the hig...
