Abstract: A printing machine includes a sliding carriage to provide isolation between internal volumes, to enable a print medium container to be exchanged without disrupting a print operation. Convective air flow between the volumes is maintained during normal operation.

Abstract: A tooling fixture for supporting a workpiece, comprising: a body including a surface over which a workpiece is in use supported and a plurality of bores therein; a plurality of supporting elements (12) for supporting the workpiece, each slideably disposed in a respective one of the bores such as to be extendable from the surface of the body; at least one fluid reservoir (9) operably in fluid communication with the supporting elements such as to cause sliding of ones of the supporting elements on displacement of the fluid in the at least one fluid reservoir, and fluid control means (53) for displacing the fluid in the at least one reservoir such as to cause the supporting elements to be extended to a supporting position in contact with the workpiece and locking the supporting elements in the supporting position.

Abstract: A tooling fixture includes a plurality of cylinders in a module fitted with pistons in which a portion thereof extends from the surface of the module. The cylinders are connected with a fluid source by a control valve assembly. The control valve assembly controls the amount of fluid to enter the cylinders in order to raise the pistons until a portion thereof are in contact with and support a workpiece. Once all of the pistons are in contact with and are fully supporting the workpiece, the fluid pressure is stabilized, maintaining the pistons at their set heights. Once the pistons are desired to be lowered, the valve assembly opens and the fluid can freely exit the cylinders and retract the pistons back into the module.

Abstract: A tooling fixture for aligning and supporting multiple substrates removed from a carrier for further processing, comprising a plurality of vacuum towers attached to a base for supporting said substrates, and a plurality of tapered pins attached to a secondary base for initially aligning said substrates, lifting them from said carrier, and supporting them until said substrates are supported by said vacuum columns.
