Abstract: Rescue harness devices are designed for incorporation into protective coats of firefighter or other types of first responders such that when deployed, the rescue harness forms a closed loop that cinches around an upper torso region under the armpits of an individual donning the protective coat, to thereby positively secure the individual and pull directly on the individual's body.

Abstract: A cleaning and lubricating apparatus for a dental handpiece or other device includes a handpiece mounting base having a handpiece mounting structure; a lubricant reservoir; a compressed air chamber; a compressed air source connection structure in fluid communication with the compressed air chamber and with the lubricant reservoir; a valve pin and a valve pin slide passageway extending from a slide passageway opening in the mounting base to the air chamber and slidably containing the valve pin so that the valve pin has a valve pin exposed end extending outwardly from the mounting base and the valve pin a valve pin inward end and has a lateral lubricant delivery depression and is fitted with at least one sealing structure positioned at the point along the valve pin at which the slide passageway meets the air chamber; a lubricant deposit passageway extending between the lubricant reservoir and the slide passageway for delivering lubricant into the lubricant delivery depression.
