A linear thruster is disclosed in which a load beam is linearly moved by fluid power relative to a guide beam and a piston. The beams are multisided in cross-section to substantially increase the linear bearing area between the bodies and, thereby, substantially increase the strength of the linear thruster against side forces as well as moments to which the linear thruster might subjected. Internal positioning of the components and energy transmission are maximized and the stroke may be variably adjusted.

Linear thruster

A linear thruster is disclosed in which a load beam is linearly moved relative to a guide beam by fluid power. One or both of the beams are multisided in cross-section to substantially increase the linear bearing area between the beams and substantially increase the strength of the linear thruster against side forces as well as moments while permitting a substantial reduction in the volumetric space consumed by the linear thruster. The fluid power and the energy inputs to the linear thruster may all be positioned at one end of the guide beam.

Device for retrieving the free end of a roll of film from a film cartridge; curved inner and outer jaws are movable with respect to one another. The operation involves inserting the jaw ends into the cartridge, rotating the film within the cartridge until the free end is between the jaw ends, and grasping the film with the jaw ends.
