One group of the light emitting diodes is operative to generate a primary blue light, a second group of light emitting diodes is operative to generate a primary green light, and a third group of light emitting diodes is operative to generate a primary red light. Varying combinations of these primary lights produces a plurality of color back lighting which are reflected and refracted by various reflective and refractive patterns to enhance the visibility and aesthetic appearance of the indicia.

Abstract: The plastic snap buckle is provided with a safety latch slidably mounted to an elongated bar of the male plug of the buckle. The latch member is generally rectangular shape having a length equal to the distance between two arcuate portions formed in the free end portion of two flexible arms of the male plug. The latch member may be slidably to locate between the arcuate portion of the flexible arm so as to prevent the flexible arms to be operated inadvertently or forcefully to release the engagement between the male plug and the female receptacle.

Abstract: The foldable display stand has a stepped display shelving portion removably mounted over a foldable support base.

Abstract: A string hopper making machine has a dough container removably mounted in a vertical manner in a frame. An extrusion piston is mounted on a vertical rod extending through a vertical guide channel formed in a guiding block mounted on the frame. The vertical rod is pivotally mounted to a front end of a lever arm which has a rear end pivotally mounted to a pivot arm of a pivot block rotatable relative to the frame. An elongated handle rod is mounted at a front end of the lever arm and is operative for pivoting the lever arm for moving the piston in an up and down vertical direction for mounting the dough container to the frame and for extruding the dough mixture from the dough container to form the string hopper.

Abstract: Two slidable carriages of identical construction are slidably mounted in a welding device side by side and move alternately 180 degrees out of phase with each other in a linear reciprocating movement. Pivotal gripping plates are mounted on the slidable carriages which alternately clamp on selected gaps between flux coating sections of the welding electrode to advance it continuously towards the work piece. Crank shafts are incorporated in the welding device to produce the linear reciprocating movement of the two slidable carriages, and cam wheels and pivotal bars are provided to locate alternately one group of gripping plates in the closed position to carry the welding electrode forward while the other group of gripping plates are in the opened position to facilitate the welding electrode to advance.
