Abstract: Prosthetic joint replacement ensemble includes an artificial joint implant component having a non-bone-interfacing rough surface for ingrowth of fibrous tissue, preferably about a peripheral boundary. The component can be made of metal, and have the rough surface provided by porous metal coating. When the prosthesis is implanted, the extramedullary rough surface engenders ingrowth of soft fibrous tissue so that it forms, as it were, a reconstituted capsular “bag” in which wear debris from the joint, for example, ultra high molecular weight polyethylene wear debris, is trapped, thus keeping those particles from gaining access to supporting bone at the bone-prosthetic interface. And so, with mitigation of wear debris dispersion, debris wear-induced osteolysis can be ameliorated.

Abstract: Embodiments of a key system for filters and their connecting heads/holders are shown. The filter cartridge and its holder each have a keyed surface, one being a protruding “key” and one being a recessed “lock”. Cooperation of these keyed surfaces is required in order for the filter cartridge to be installed in the holder, so that mismatched cartridges cannot be installed into the holder, for example, to prevent a particular type of cartridge from being placed in a filtration or other process where it would be inappropriate, or undesired. The keyed surfaces are selectively locate-able preferably at different circumferential locations on a perimeter of the filter and a corresponding location on a perimeter of the head/holder. The perimeter may be, for example, on an outer shoulder surface of a filter and an inner surface of a valve head, or on outer and inner surfaces of connectors that provide a liquid seal between the filter and the head/holder.

Abstract: A fuel vapor handling apparatus supplies a purging air to a canister by using a purge pump and purges fuel desorbed from the canister into an intake pipe. A controller intermittently operates the purge so that the canister internal temperature recovers from a reduced level caused by the latent heat of vaporization of fuel during an operating period of the purge pump. Therefore, desorption of fuel from the canister during an operating period is facilitated. Since the actual operating time of the purge pump is reduced, the life of a motor that is a power unit of the purge pump becomes longer.
