Abstract: A covering arrangement for an animatronic arrangement, the covering arrangement having a laminated structure comprising: an outer stretchable polymer layer having a thickness of between 0.5 to 5 mm; and a foam layer configured to provide desired bulk and form to the covering arrangement, wherein the foam layer comprises a shaped foam preform formed from precast flexible foam sheets.

Abstract: A spool assembly configured for use in a two-stage proportional control valve in a fluid system includes a substantially cylindrical sleeve having an axially extending sleeve bore extending from an open first end to an open second end. A spool includes a spool bore that extends from an open first axial end to a closed second axial end and is slidably mounted within the sleeve bore. The spool further includes a first circumferentially extending groove defining a fluid flow path, a second circumferentially extending groove formed near a first end thereof, a third circumferentially extending groove formed near the second axial end thereof, a circumferentially extending pressure groove formed therein between the second axial end and the third circumferentially extending groove, and first, second, and third transverse fluid passageways formed through a side wall of the spool.

Abstract: A test equipment arrangement includes a superheat controller configured for connection to a unit under test, and further configured to test at least one operational parameter of the unit under test.

Abstract: A two-stage proportional control valve configured for use in a fluid system includes a valve body having a longitudinally extending valve body bore formed therethrough. A first stage microvalve is mounted within the valve body bore, and a second stage spool assembly is mounted within the valve body bore downstream of the microvalve. The second stage spool assembly includes a sleeve and a spool slidably mounted within the sleeve.
