A camera retractor assembly for a furnace includes a faceplate configured to be attached to a furnace; a retractor carriage configured to be attached to the faceplate; a pneumatically operated retractor slidably supported by the retractor carriage; a camera enclosure attached to the retractor; a lens tube attached the camera enclosure; and at least one of a control panel, an air manifold or an air reservoir attached to the camera retractor assembly.

Camera retractor mechanism

A pneumatic linear actuator with a manually adjustable stop mechanism integrated into the device such that the actuator mechanism and the stop mechanism are co-linear. The stop mechanism limits the travel of the actuator by turning a handwheel. The mechanisms are completely sealed and/or enclosed and a gear-reduction position indicator is included. Forward and reverse acting variations are presented.

Apparatus and method of fluid powered linear actuators with adjustable stops

An improved apparatus for cleaning linearly translating rods is described. Embodiments of the invention are suitable for use where a rod, such as a cleaning rod, is moved linearly through a stationary support, generally a cylindrical tube, such as a pneumatic cylinder, with bushings fixed inside the tube through which the rod slides. Preferred embodiments of the present invention allow the rod scraper to be attached or removed without disassembling the complete hydraulic cylinder rod apparatus. Preferred embodiments of the present invention also allow the rod scraper to float radially while its motion is constrained axially. This allows the invention to compensate for lateral displacement of a translating cylindrical cleaning rod due to normal working clearances between the cleaning rod and bushings or by bushing wear over time.
