Abstract: A light fixture having a uplight shade with an elongate downlight aperture includes a removable baffle configured to cover the elongate downlight aperture to control the amount of downwardly directed light. The light fixture includes an elongate ballast/electronic housing having opposing ends, and elongate side panel having opposing ends, and a pair of end pieces supportingly engaging the opposing ends of the ballast/electronic housing and the opposing ends of the side panels. The housing and side panel are laterally spaced apart, and together with the end pieces define an elongate downlight aperture. The side panel is positioned and orientated with respect to a light source mounted between the end pieces to act as a shade which reflects light upwardly from the light fixture.

Abstract: A crosshead system for a swashplate engine such as a Stirling cycle type. A plurality of crossheads are constrained to move in a reciprocating fashion by travelling along a pair of parallel guide rods. The crosshead system further includes a mechanism for adjusting a clearance between the crosshead elements and the opposed parallel face surfaces of the rotating swashplate. The adjustment mechanism includes a threaded adjuster cup which is maintained in a lock position through a fastener which drives a conical cone into the conical inside surface of the adjuster sleeve thus fixing its rotated and hence linear position.
