Abstract: A rotary bit configured to deburr and swage an end of a tube, comprising a first end configured to deburr and swage the end of the tube, and a second end configured to be secured to a rotary device, wherein the first end includes a plurality of blades that extend axially along the first end and radially outward from the rotary bit, the plurality of blades including a plurality of leading blades and a plurality of finishing blades, the leading blades configured to initially deburr and swage the end of the tube upon insertion of the rotary bit into the end of the tube, and the finishing blades configured to complete deburring and swaging of the end of the tube, the finishing blades extending radially outward from the rotary bit to a greater extent than the leading blades.

Abstract: A connection joint for coupling a pair of conduits. The connection joint includes a tubular body having an inlet end and an outlet end that are each configured for receipt of a respective conduit therein. A first membrane seal is located within the tubular body and spaced apart from the inlet end, and a second membrane seal is located within the tubular body and spaced apart from the outlet end. The first and second membrane seals each have a bulbous portion located proximate the inlet end and outlet end, respectively, a tubular sleeve unitary with the bulbous portion located away from the inlet end and outlet end, respectively, and a plurality of radially inwardly extending ribs.

Abstract: Detection of leakages of refrigerant from compressor-evaporator-condenser circuits is carried out with an electron multiplier equipped mass spectrometer of which the evacuated detector chamber is maintained at substantially constant elevated temperature in the range about 60 to about 130.degree. C. This allows high gain settings to be employed allowing detection of very small leakage rates by direct sampling from the ambient atmosphere while distinguishing from chemically analogous halogenated hydrocarbons used as blowing agents for foamed insulation and present in substantial concentrations in the ambient atmosphere.
