Abstract: A decorative alert system includes an alerting circuit arrangement disposed in a casing, which includes a central process circuit and a sparkling control circuit, wherein the alerting circuit arrangement electrically connected with a centrifugal sensor for controlling the alerting circuit arrangement by switching on and off of a power source. When a centrifugal force is applied on the alerting circuit arrangement, the alerting circuit arrangement is electrically connected with the power source, so as to electrically connect with the central process circuit and the sparkling control circuit. So, a plurality of illuminators controlled by the sparkling control circuit are lightened up for illuminating sparkling lights to signify as an alert signal.

Abstract: A tool guide bushing mounting assembly comprised of a bushing liner which has a threaded sleeve for a locking screw secured to it with an adhesive. The locking screw sleeve is secured to the liner with a metal carbide epoxy securely positioning the sleeve relative to the bushing liner. The bushing mounting assembly may then be cast into a tool guide sometimes called a jig with the liner flush with the top and bottom surfaces of the jig, assuring proper positioning of the locking screw with respect to the bushing. The universal bushing mounting assembly may be used with either slip renewable, slip/fixed renewable or fixed renewable bushings.
