IPC: F16F9/02
Filed: 1998-06-29
Abstract: A suspension system (10) for a bicycle or other vehicle or apparatus, the system including at least one telescoping strut comprising a first telescoping member (12) and a second telescoping member (14), the first and second telescoping members being telescopingly and coaxially engaged with each other so that the strut is compressible by relative movement of the telescoping members toward each other and expandable by relative movement away from each other. A piston (16) may be interconnected with the second telescoping member and slidably positioned within the first telescoping member. The piston separates a primary compression spring chamber into two gas chambers (30, 34) connected by an adjustable port, whereby compression or expansion of the strut creates a damping force that resists such relative movement of the telescoping members, resulting in the primary compression spring having a frequency-sensitive spring rate. The crack force, spring rate and other characteristics of the suspension system may be adjusted using a piston location adjuster to adjust the piston height, and/or a negative preload spring to apply a compressive preload force to the telescoping strut.

Abstract: A magnetic separator for use in conjunction with a fluid catalytic cracking system has roller devices incorporating permanent magnets with a moving device that receives catalyst particles and passes over the magnets.      The permanent magnets may be incorporated into a roller device which moves a flexible belt that receives catalyst particles from the fluid catalytic cracking system and passes them over the magnets. The particles are deposited on the belt and travel to the roller having the magnets. Older, less effective catalyst particles are attracted to the magnets on which the belt is rotated and are held by the magnets longer than newer, more effective catalyst particles. The permanent magnets are high strength neodymium/iro/boron magnets in one embodiment and samarium/cobalt magnets in a second embodiment. The magnets are stacked S-NN-SS-NN-SS-N  to provide a more effective magnetic field. In the first embodiment, high strength magnets made from neodymium/iro/boron operate efficiently at 250°F without extensive cooling equipment. In the second embodiment, high strength magnets made from samarium/cobalt operate efficiently at 450°F without extensive cooling equipment.
