Such pins are adapted for being engaged by grooves formed in the opposite lateral sides of a channel shaped diffuser such that the diffuser may be detachably mounted from the end caps.

Abstract: An apparatus for diffusing light and for directing circulation of air. A support (3), a grill panel (2) and a socket (12) are mounted together to form the apparatus. The support (30) is mounted to a base (64, 68). A nozzle (94) within the base (64, 68) creates a venturi effect by providing an emerging airstream which causes air to flow upward through the grill panel and then out to mix with the emerging air-stream. The grill panel (2) is cleaned of particulate matter because of the flow of the air through the grill panel. The emerging airstream travels in the same direction that it travelled when passing from the inlet to the outlet of the nozzle.

Abstract: A flexible light guide consists essentially of a flexible tube made of an amorphous fluoropolymer based on a combination of terafluoroethylene and a fluorinated cyclical ether, and a transparent liquid filling the tube. The liquid has an index of refraction which is higher than that of the material of the tube. The light guide may be provided with means for continously passing the liquid through the tube. In this case, the liquid may be physiological sodium chloride solution and the light guide may be a part of an endoscopic illumination device useful for endoscopic coagulation.

Abstract: A light fixture and/or bath cabinet is provided such that the bath cabinet can be surfaced or recessed mounted. Regardless of whether the bath cabinet is surfaced or recessed mounted, side covers and members are provided for covering the mounting hardware and sides of the cabinet and light fixture to present an overall aesthetically pleasing finish. The bath cabinet and light fixture generally avoid the use of hardware by utilizing extruded members which interlock together. When the bath cabinet is recess mounted, the light fixture is secured directly to the mounting wall directly above the cabinet. On the other hand, when the bath cabinet is surface mounted to the wall, the light fixture is secured to the top of the bath cabinet by a clamping member.

Abstract: An illuminated fountain includes a housing with a water chamber in the housing having a cap with perforations and a transparent bottom panel, a lamp in the housing and a mirror for reflecting light from said lamp through the bottom panel of the water chamber. A source of electrical energy is connected to the housing and a pressure switch in the housing is connected between the electrical energy source and the lamp. The pressure switch has a fluid connection with the inlet to the water chamber such that it delivers current to the lamp only when water is flowing to the chamber.
