A folding means for bag knitting apparatus which is intended to fold inwardly the text-printed side portion of the double-layer material strip to be folded to overcome the problems of the conventional bag knitting apparatus, and comprises a clamping roller set, a folding rod set, a supporting set, and a pressing wheel. The double-layer material strip to be folded is opened and enclose the bottom of the folding rod such that the both side portion is placed between the grooves outside the folding rod and the pressing wheel, therefore the material strip is folded as it moves upward through the grooves outside the folding rod and the pressing wheel.

A stand (8) for supporting an artificial tree of a type having a plurality of optical fibers comprises: a housing (4) having a base (3) and a sidewall defining one or more windows (6), a screen (9) in each window (6), an internal light source (54), a decorative image-bearing material (38) or shape arranged between the light source and the screen, and a tree trunk supporting sleeve (20).

A driving device for handicrafts with acousto-optic control and driven by batteries comprises a base, a switch and a power connector at a base cavity of the base, a motor in the base which controls a rotating axis that extends to the surface of the base, a rotating plate connected to the rotating axis, a frame mounted on the rotating plate, a strip structure on external side of the frame with teeth structures on each side respectively which can slide in a sliding groove, a hole leading into the base on each side of the sliding groove respectively, small lamps under the holes, a pipe in each hole where handicrafts can be fixed, a gear mounted on the pipe to match the teeth of the strip, a battery compartment and a control circuit in the base which includes a sound inductive circuit and a light inductive circuit.

An add-on vehicle light monitor includes a light pipe formed of a light coupling transparent material and having an input end and an output end. The light pipe is configured to be supported upon the vehicle body at a position in which the input end is approximate to the to-be-monitored light source and the output end is viewable by the vehicle driver or operator. In one embodiment, an aperture is formed within the vehicle taillight lens to permit the input end to be inserted into the vehicle light assembly. In an alternate embodiment, the input end is fabricated so as to be flush mountable to the light assembly lens without the need for forming an aperture therein.

A fiber optic light system is provided including a light assembly having a pair of lights adapted to illuminate upon the receipt of power. Also included is a flasher unit connected to the lights for intermittently supplying power to the lights. A plurality of fiber optic strands are provided each including an inboard end mounted on the light assembly. A plurality of modules are each mounted along the strands for emitting light passing through the corresponding strand.
