Abstract: A vest has a back and a front with a vertical opening, laterally spaced sides with arm holes, a neck hole, a waist hole, an interior surface and an exterior surface. A plurality of front light emitting diodes are on the front of the vest and a plurality of back light emitting diodes are on the back of the vest. A battery and a plurality of solar panels on the vest power the light emitting diodes.

Abstract: A lower support is provided between the side edges of the roof beneath. The lower support is in contact with the roof adjacent to the exterior edge. Upper supports are provided above and in contact with the roof. The upper supports include upper exterior, interior and intermediate supports. The upper exterior support is adjacent to the exterior edge. The upper interior support is adjacent to the interior edge. Central supports extend between the interior and exterior edges of the roof. The lower support is provided below and the upper supports are provided above. The central supports are located above and in contact with the roof. In this manner lower intersections are formed with the upper exterior and lower exterior and central supports. Upper intersections are formed with the upper interior and the central supports. Central intersections are formed with the upper intermediate and central supports.

Abstract: A cooling jacket assembly is made for an electric motor or generator. A hollow cylindrical housing is cast with an outer peripheral surface and an annular axially facing end surface, a plurality of grooves formed in the outer peripheral surface and a radial lip at one end. The outer peripheral surface is machined into a smooth surface having a uniform diameter. Inlet and outlet ports are drilled through the end surface to communicate with the grooves. A pair of sealing recesses are formed in the outer peripheral surface on opposite sides of the grooves, and an O-ring seal is placed in each recess. A cylindrical sleeve is slid over the outer peripheral surface of the housing until it engages the lip and so that the sleeve slidably engages the outer peripheral surface and sealing engages the seals.
