US Patent:

40413063, Aug 9, 1977

Filed:

Dec 15, 1975

Appl. No.:

5/640466

Inventors:

Wayne W. Compton - Irvine CA
Robert Paul Draper - Sunland CA

Assignee:

Kim Lighting, Inc. - City of Industry CA

International Classification:

F21V 709

US Classification:

240103R

Abstract:

A luminaire which casts a substantially rectangular pattern of light on a surface. It utilizes a lamp which has an axis of radiation and the property of emitting a disproportionately larger percentage of its luminous flux in an annulus which lies between a substantial bounding region at each end of the lamp. A reflector includes a cavity in which the lamp is placed. The reflector has a cutoff edge that forms an aperture opening from the cavity. Support means mounts the lamp in the cavity above the cutoff edge. Specular reflecting means is provided in the reflector to reflect light which is initially directed above the cutoff edge to the surface as supplementary light to fill in areas where light that is directly emitted through the aperture without reflection does not provide proper illumination to the surface.

Abstract:

A fluid flow monitoring device includes a housing defining a fluid flow passageway. A vane positioned within this passageway moves to positions which vary in accordance with the rate of fluid flow therethrough. An armature coupled to the vane pivots to positions corresponding to the vane positions. A submersible transformer in proximity to the armature produces an output signal indicative of the armature position and the fluid flow rate. The output signal is fed to a meter where the fluid flow rate is represented. A bypass passageway is provided for fluid flow therethrough in the event the fluid passageway becomes obstructed.
