The cold finger has a first end and a second end.

A cold finger shrinks while a hot finger expands causing inaccurate readings.

A cold finger shrinks while a hot finger expands causing an inaccurate reading.

Additionally, the structural integrity or stiffness of the cold finger and/or displacer can be strengthened.

A cryogenic cooler (10) includes a dewar (14) spaced from a cold finger (12).

The cold finger is positioned within the void region of the Dewar creating an annulus.

Various uses of the cold-finger (24) to facilitate the conduct or completion of a chemical reaction are described.

Death beckoned toward me with his cold, bone fingers.

A cold finger (408) of the cryocooler (102) extends within the dewar (420) and may prevent overfilling of the dewar (420).

Variations of a cryostat may also include a gas expander portion that replaces the coldfinger of typical IDCAs.

The apparatus includes a cold finger (10) incorporating primary and secondary working volumes and their associated regenerative beds (22).

The thermal lengths of the cold finger and/or the displacer can be extended by minimizing their geometrical lengths.

At the bottom of the hearth, a cold finger orifice is provided to permit the withdrawal of refined metal from the cold hearth apparatus.

A cold finger (80) is positioned within the superinsulation panel (30) to transfer heat energy from the cold sink (70) to the thermoelectric device (52) which in turn transfers the heat energy to the hot sink (60).

In one embodiment, the regenerator matrix has a serpentine shape or U-shape disposed around the displacer and the cold finger.
