Abstract: A fluorescent work light having a cover with restraining elements for restricting the movement of the fluorescent lamp. The restraining elements are inwardly projecting integral portions of the cover and restrict the lateral, rotational and axial movement of the fluorescent lamp. The work light also includes a rotatable socket with permits the cover to be threadingly engaged to the handle while rotationally engaging the fluorescent lamp. The distal end of the cover may consist entirely of transparent material to thereby permit light to be emitted from the distal end of the cover in all outward directions.

Abstract: A flashlight which comprises a barrel for containing two battery cells, said barrel having opposite ends and an internal detent/recess, head and tail pieces provided at respective barrel ends, a light bulb enclosed by the head piece, and an on/off switch. The switch has a resiliently biassed projecting post and is provided inside the barrel at a position between and for switching on and off electrical connection between the light bulb and the battery cells. The post is arranged to engage automatically with the detent/recess in a snap-fit manner when the switch is moved into the barrel through one barrel end to the aforesaid position, thereby holding the switch in that position.

Abstract: A method and apparatus is provided whereby a shadow mask support pin can be forced into a cathode ray tube panel without having to use any panel support post. Three or four support pads are utilized to support the bottom edge of the skirt portion of the panel. Each of the support pads may be elevationally moved by a drive unit. First through fourth distance sensors serve to detect the height of corner points on the interior surface of the panel face portion. A control device is adapted to control the operation of the drive unit in a manner that the corner points are brought into a predetermined reference plane before the support pin insertion proceeds. A fifth distance sensor may be further employed to detect the height of a center point.

Abstract: A novelty shadow projecting lamp is disclosed having at the center a light source contained in a protective enclosure. A portal or opening lets light escape in a predetermined direction, and is in visual communication with and surrounding a light source enveloped by a bi-phased liquid. The bi-phased liquid includes bits of meltable wax. A heat source located in the base portion of the lamp, is in thermal communication with the liquid. As the heating element melts the wax, which is suspended in the liquid, the wax melts and floats freely in the liquid, thereby passing through the light source and casting shadows onto walls and surrounding area.
