An adsorption vessel comprising a packed bed region of adsorbent particles contiguously arranged, comprising a perforated adsorbent particles, a gas separation process using the perforated adsorbent particles, and methods for making the perforated adsorbent particles. The perforated adsorbent particles each comprise an adsorbent material where the perforated adsorbent particles each have at least 10 channels extending through the particle. The equivalent diameter of the channels may range from 0.05 mm to 1.5 mm, and the void fraction of the channels may range from 0.05 to 0.5.

Perforated adsorbent particles

A cryogenic fluid jet is used in an apparatus and a method for remote cooling of a cutting tool engaged in machining a workpiece under high-energy conditions, such as high-speed machining, hard-turning, cutting of difficult to machine materials, and combinations thereof. The apparatus and method use a stabilized, free-expanding cryogenic fluid jet having a pulse cycle time less than or equal to about 10 seconds. The apparatus and method increase the cleanliness of machined parts and chips and machining productivity of hard but brittle tools, including but not limited to tools which should not be cooled with conventional cooling fluids.

Apparatus and method of cryogenic cooling for high-energy cutting operations

A cryogenic fluid distributor for turret machine tools (e.g., lathes) directs a stream of cryogenic fluid from an external, pressurized cryogen source to a working position of a machine tool to prevent overheating of the tool. Designed for easy retrofitting and synchronizing with multi-tool turret machines, the distributor allows for a &ldquo;dual-fluid&rdquo; machining capability combining a cryogenic fluid and a conventional cutting fluid (flowing via a conventional coolant system built into a given machine tool). Made of low thermal-mass, insulating polymer and metallic parts, the distributor utilizes the different thermal contraction coefficients of the parts to establish cryogenic sealing connections, which eliminates undesired turret plate cooling and assures rapid cryogen flow start-up.
