Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
133 words
A solid-state photocontrol housing assembly comprising; an inverted cup-shaped housing including an annular sidewall having an opening therein, and a plurality of external heatdissipating ribs thereon, a first locating and mounting means within said housing for locating and mounting a control transformer, a second locating and mounting means within said housing for locating and mounting a printed circuit board, a flanged slot surrounding said opening in said housing wall, a light-transmissive window member having a flange thereon perpendicular to said window, said light-transmissive window being slidably received in said flanged slot surrounding said opening in said wall, and a bottom closure member closing off the bottom of said inverted cup-shaped housing, said bottom closure member coacting with the flange on said window to thereby maintain said lighttransmissive window seated within said flanged slot.
Claim 2
Dependent Claim
