Title: Boat light assembly
IPC: F21V19/00
Filed: 1981-03-27
Abstract: A boat light assembly includes a shield 12 recessed within the hull H of a vessel. A conventional sealed beam head-lamp unit 38 seats in a part- spherical lamp unit retaining member 37 formed of a resiliently flexible soft material such as rubber. The retaining member 37 seats in a complementary part-spherical portion of the shield 12, so that the retaining member 37 can be universally adjusted to a selected position within the shield 12, to adjust and hence correctly aim the headlamp unit 38. The retaining member 37 is quickly and firmly secured, in each position to which it is adjusted, through the provision of a soft rubber mounting ring 28 which fits over the inner end of the shield 12 and has a part-spherical interior to contact the retaining member 37. Upon tightening of a metal clamping ring 34 which extends around the mounting ring 28, the mounting ring 28 is contracted in a radially inward direction, to tightly grip and secure the retaining member 37. <IMAGE>

Patent GB-2143136-A (GB)
Title: Respirator face mask
Inventor: MATHESON JAMES N
IPC: F16K15/14
Filed: 1983-06-29
Abstract: A respirator face mask is formed from a silicone or other vulcanized rubber with a multi-compound curved face seal having a superior configuration for facial fit. The mask is held by four support buttons and two straps attached thereto having a reverse leverage pulldown effect to pull the mask into contact with the facial area. The four attachment means for the straps are eccentric buttons having an undercut that overrides a loop that can be easily disassociated when the attachment loop is reversed and pulled over the button. A concave configured sealing diaphragm on the exhalation valve provides for substantially uniform opening with less effort than is normally encountered in such valves. A staggered anti-inversion rib on the concave underside of the exhalation valve prevents the diaphragm from inverting to a convex configuration. The valve includes an exhalation valve stack and vent that can be covered at a sharply chamfered opening to provide for a pressure fit test. The foregoing respirator provides a unique collar button for holding an eyelet to which the band assembly is attached and incorporates a unique exhalation valve, valve seat, valve guard and exhalation valve having a staggered offset anti-inversion rib, so as to comprise a unique and comfortably molded, compound curved sealed respirator face mask conforming to a user's face. The inhalation port features two unique chamfered exterior rings which mate with a reverse chamfered cartridge and/or filter holder in conjunction with the mask interior offset ring which mates within the threaded connector recessed housing, to effect an interlock when mated components are threaded together. This unique interlock assures a secure retention of the cartridge and/or filter to the face mask, both during use and when disassembling the filter from the filter housing. The inhalation valve is mounted on the threaded connector so as to form a slightly concave configuration to minimize the objectionable popping sound.
