Abstract: A crab trap assembly for capturing crabs includes a cylinder that may be inserted into a bottom of a body of water. The cylinder is substantially hollow to capture a crab when the crab moves along the bottom of the body of water and falls into the cylinder. The cylinder is selectively removed from the body of water to harvest the crabs in the cylinder.

Abstract: A lighting module may comprise a housing, a window frame mounted at a front side of the housing, a window mounted at a front plane of the window frame, the window comprising a window front face spanning a front plane length and first and second window sidewalls extending rearwards from first and second edges of the window front face, and an array of light-emitting elements within the housing, the array aligned with and emitting light through a window front plane and through the first and second window sidewalls.

Abstract: Lighting modules include a housing, a window attached to the housing, and an array of light-emitting elements that are positioned within the housing and emit light through the window. The window has a first surface and a second surface. The light from the array of light-emitting elements is emitted through the first surface and the second surface of the window. In some examples, the first surface and the second surface of the window are angled with respect to each other.

Abstract: A lighting fixture has a housing, a lighting module in the housing, the lighting module having a first surface containing an array of lighting elements, and a heat sink having fins, the heat sink attached to a second surface of the lighting module opposite to the first surface, the heat sink having a fin density of less than 0.25 fins per millimeter. A lighting fixture has a housing, a lighting module in the housing, the lighting module having a first surface containing an array of lighting element arranged in an array of elements along a horizontal axis and a vertical axis, and a heat sink attached to a second surface of the lighting module opposite the first surface, the heat sink having fins oriented to extend away from the heat sink along the vertical axis.

Abstract: A laminated steel mill roll consists of a core member, a reversible replaceable shell member and a retaining member. The core member has a radially-outwardly extending shoulder, while the shell member has two symmetrically-disposed radially-inwardly extending shoulders, the core member shoulder engaging one shell member shoulder for location and retention of the shell member on the core member, and the retaining member fastened to the core member engaging the other shell member shoulder. The shell member can be made as two similar reversible replaceable portions, or as a plurality of such portions at least the two endmost being similar to one another, giving even greater possibility for interchange and increase in useful life.

Abstract: Electro-chemical drilling of small diameter holes is achieved by placing an electrolyte discharge nozzle in fixed spaced apart relationship with a workpiece, heating the electrolyte passing between the discharge nozzle and the workpiece to increase the current conductivity of the electrolyte up to about 70.degree. C and forcing a jet of electrolyte across the space onto the workpiece. The electrolyte pressure and discharge nozzle orifice length are matched so as to provide an unconfined jet of electrolyte which has a constant diameter so as to obviate the necessity of relative movement between nozzle and workpiece. Increased temperature results in a fine non-conductive mist at the end of the electrolytic jet thereby providing a process for drilling holes of smaller size in the workpiece than prior procedures.A novel nozzle assembly is also disclosed adapted to produce holes in a workpiece by directing free streams of electrically charged electrolyte at the workpiece.
