Method for making contact lenses

The instant invention pertains to a method and a fluid composition for producing contact lenses with improved lens quality and with increased product yield. The method of the invention involves adding a non-crosslinkable hydrophilic polymer into a fluid composition including a lens-forming material in an amount sufficient to reduce an averaged mold separation force by at least about 40% in comparison with that without the non-crosslinkable hydrophilic polymer and to provide a disparity of about 10 N or less in mold separation force. The non-crosslinkable hydrophilic polymer has a limited miscibility with the lens-forming material low enough to successfully and timely form an intact interfacial film with a sufficient thickness at an interface between the mold and the fluid composition therein, and has a structure that minimizes entanglement of the non-crosslinkable hydrophilic polymer in the interfacial film with the polymer matrix of the formed lens.

Lubrication and cooling system

A system for reducing the refrigerant pressure in an oil sump (10) or in a cavity (352) of a housing. The invention is particularly useful for reducing pressure in a compressor (23) for heat pump applications that has been validated for water chiller operations or in turbine and generator systems in ORC systems generating electricity using refrigerant, the ORC systems essentially being a heat pump application operating in reverse. An auxiliary compressor (509), an auxiliary condenser (709) or an ejector pump (609) may be used to reduce pressure in the oil sump (10), to separate refrigerant from oil. The auxiliary compressor (509), the auxiliary condenser (709) or the ejector pump (609) may also be used to reduce the pressure of refrigerant in the housing of a compressor in heat pump applications at temperatures and pressures at which the compressor was validated for water chiller applications and of the turbine and generator in ORC applications.
