A sight glass filter and check valve apparatus for use in a fluid line. The apparatus includes a housing, first and second couplers connected to the housing, a sight glass assembly, a filter assembly, and a check valve assembly. The housing includes a pair of coordinated apertures. Each of the couplers includes a first end and a second end with the first ends threadedly received by the housing and the second ends connected to the fluid line. The sight glass assembly is disposed within the housing in alignment with the apertures. The filter assembly is disposed between the housing and the first coupler. The check valve assembly is disposed between the housing and the second coupler.

An EMI/RFI shielded housing for an electrical apparatus comprises a case member and a complementary cover member, each comprising an end wall portion and a side wall portion together defining substantially continuous and unbroken peripheral surfaces. The side wall portions of these members are respectively configured for an interference fit therebetween to define an assembled condition of the housing. This interference fit is defined by the side wall portion of the case member being received interiorally of the side wall portion of the cover member. Moreover, substantially the entire inner surfaces of the end wall portions of both case and cover member are electrically conductive, substantially the entire inner surface of the side wall portion of the case member is electrically conductive and major fractional portions of respective facing surfaces of the assembled and interference-fitted side wall portions are electrically conductive. All of these conductive surfaces are electrically coupled when the case is assembled to define a continuous shield. However, the exterior surfaces of the end wall portions of both cover and case members, the exterior side wall portions of the cover member, and minor fractional portions of the facing surfaces of the case and cover member, respectively, are electrically non-conductive.

EMI/RFI Protected enclosure

An acoustic telephone coupler for use in transmitting medical data over telephone lines and adapts to accommodate any telephone handset configuration. The slim coupler base further functions as a spool for a lengthy cable, and a dual purpose strap alternatively retains the cable and cable connector on the spool or a telephone handset against the transducers of the coupler.
