Abstract: A cryogenic cooling system is provided having a vessel, the vessel comprising extending along a longitudinal axis and configured to receive a sample probe movable along the longitudinal axis. One or more cooling members are thermally coupled to the vessel so as to produce a thermal gradient along the longitudinal axis of the vessel. A vent extends along the outside of the vessel and is configured to provide a pathway for a flow of gas from an inlet of the vent to an outlet of the vent. The inlet is in gaseous communication with the inside of the vessel and the outlet is in gaseous communication an environment external to the vessel. The inlet is arranged at a position along the vessel configured to obtain a temperature below 63 kelvin during operation of the one or more cooling members, and the outlet is arranged at a position configured to maintain a temperature above 273 kelvin when the outlet has a temperature below 63 kelvin.

Abstract: A hydraulic cylinder includes a cylinder assembly defining a cavity; a piston rod having an inboard end and a rod axis; a taper lock piston assembly including a piston head with a central bore and a head axis, and wherein the inboard end includes a first exterior tapered portion having a first non-zero cylinder taper angle and the central bore defines a piston tapered portion having a non-zero bore taper angle that is the same as the first cylinder taper angle; and wherein the piston head is received on the inboard end with the first exterior tapered portion in circumferential abutment with the piston tapered portion.

Abstract: A hydraulic cylinder includes a cylinder assembly having a cylinder, defining an inner hydraulic chamber and being for reciprocating receipt of a piston and piston rod therein; a piston rod extending from the inner hydraulic chamber exteriorly of the cylinder; and a piston head assembly connected with the piston rod and disposed for reciprocation within the cylinder assembly. The piston head assembly includes a piston head and a valve assembly including a passageway defined in the piston head and a valve member having an outer surface and being sized and configured for reciprocation in the passageway between extended and retracted positions therein, the valve member defining at least one flat defined along the outer surface and at least one transition surface between the outer surface and the flat, the transition surface forming an angle with the flat of between about 40 and 50 degrees.

Abstract: A method, system and computer program for processing software modules is provided. Each software module has a version management file associated with it. A version management file includes a comment field for recording at least one tag. Each tag relates to an attribute of the associated software module and has an attribute value. In operation, when an attribute of a software module needs to be known, the comment field of the version management file of the software modules is searched for a predetermined tag. The attribute value that is associated with the predetermined tag is detected when said predetermined tag is found. Processing of the software module is then selectively effected in accordance with the attribute value when said predetermined tag is found, and in accordance with the lack of a predetermined tag when said predetermined tag is not found. The version management file includes history data defining current and prior versions of the software module.

Abstract: An apparatus and method for electrical cable identification that is both expeditiously and easily deployed, lightweight to facilitate on-person portability, and provides quick on-site identification of both primary and secondary cables, including grounded secondary cables/conductors.
