Abstract: A frame assembly for a fuel cell power module, particularly but not exclusively for use in lift trucks, has at least one frame element. The frame element is provided with an internal cavity that is filled with a fill material to provide a desired mass of the frame assembly. The frame assembly is configured to receive a fuel cell stack and other balance of plant components of a fuel cell power module and may also be configured to receive a fuel storage vessel. The frame assembly can be configured so that it can replace a battery pack of a lift truck and still provide adequate counterweight.

Abstract: A system includes power modules received within a frame of a ventilation enclosure. Each of the power modules has a fuel cell stack. A ventilation shaft is arranged along a rear side of the ventilation enclosure and sealingly receives the power modules so that exhaust outlets of the power modules discharge into the ventilation shaft. Each of the power modules is removably attachable to the ventilation shaft through the front side of the ventilation enclosure. A fuel supply pipe in the ventilation shaft supplies fuel to fuel inlets of the power modules. An exhaust pump draws exhaust fluid out of the ventilation shaft.

Abstract: The disclosure provides an adjustable castor wheel assembly for attachment to an object and a system for supporting an object comprising a plurality of wheel assemblies. The adjustable castor wheel assembly comprises a mount constructed to be attached to the object, and a stud extending from the mount in an axial direction. The assembly also comprises an adjusting member rotatably engaged with the stud so that a rotation of the adjusting member in a first direction causes a distance between the mount and the adjusting member in the axial direction to increase while a rotation of the adjusting member in a second direction causes the distance between the mount and the adjusting member in the axial direction to decrease. The assembly also comprises a castor wheel rotatably attached to the adjusting member.

Abstract: A copier or printer is pivotably attached to a finisher module, such as for stapling. A pivotable mount is disposed toward the back of the copier, so that an opening can be formed toward the front of the copier, exposing an interface between the copier and the finisher module. A latch is used to hold the finisher module to the copier in a closed position.
