Abstract: The present invention relates to a lens retaining clip designed to hold a lens in place in the light path of a light bulb. This invention has two preferred embodiments designed to work with either an MR-16 light bulb or a PAR-36 light bulb. The primary difference between the embodiments is the shape and function of the retaining arms spaced around the perimeter of the retaining clip. Each embodiment of the present invention comprises a generally circular main bracket, and one or more, preferably three equally spaced, retaining arms. The main bracket is narrow in relation to the total diameter of the top member so as not to obstruct the light path of the light bulb. Retaining arms are attached to the outer edge of the main bracket and each are designed with an indented portion designed to “clip” onto the light bulb and retain the lens retaining clip on the bulb. In operation, the lens retaining clip secures a lens of generally the same shape and size as the lens retaining clip against a light bulb.

Abstract: This invention relates to a lighting fixture support with a pivoting mounting bracket. More specifically, this invention is aimed at providing a well-type lighting fixture for use in outdoor, below ground lighting settings which is easily positioned at various angles with respect to the ground. The inventive mounting bracket comprises a first bracket which is connected to a second bracket at a pivot point. One or more dimples on either of the brackets are operatively connected to one or more sets of ratchet teeth on the other bracket. The dimples and sets of ratchet teeth cooperate to secure the first bracket into discrete positions about the pivot point with respect to the second bracket.

Abstract: Disclosed is a novel apparatus for the practice of use and simulation of a snare drum. The present invention provides a practice drumming pad that can reproduce the sound and feel of a snare drum, thereby allowing the user to practice proper rhythm and technique to produce the desired results when using a real snare drum. The practice pad of the present invention consists of a substrate having a rubber pad on the top surface, a recessed channel in the bottom surface, and a sound generating device consisting of a layer of pellets contained between two rigid plates secured in the recessed channel. The rigid plates and layer of pellets are secured in the recessed channel so as to allow little more than vibrational movement of the plates and pellets in the recessed channel. As one “drums” on the rubber pad, the vibrations are transferred to the plates and pellets to simulate the sound produced by a real snare drum.

Abstract: An improved two-piece roof flashing comprises a thermoplastic hard base and an elastomeric rain collar. The hard base comprises a planar base plate with a central dome-like portion, with the dome-like portion having a central opening with a solid flange inwardly disposed and encircling the opening. The rain collar has a central opening sized to accommodate an upstanding roof pipe. The rain collar is molded directly onto the solid flange of the hard base, with the resulting seam between the rain collar and hard base being strong and weathertight. When the collar is molded onto the flange of the base element, the materials of the collar and flange fuse together along the seam between the collar and base element. Additionally, with the collar directly molded to the flange, the design of the flange creates a lengthy path that water must traverse in order to penetrate the roof flashing.
