Abstract: An apparatus comprising, a monolithic crystal comprising a substrate portion and at least one oscillator; a first electrode provided at a first location of the oscillator; a second electrode provided at a second location of the oscillator; a gap separating the oscillator from the substrate portion, exposing a side surface of the oscillator; and one or more tethers that extend across the gap so that the oscillator is supported by the substrate portion.

Abstract: A toilet flange cover system for temporarily covering a toilet flange and opening during periods of construction and remodeling when the toilet is not installed. A cover is fabricated of a rigid plastic material and formed with a generally circular shape. Diametrically opposed locking posts are integrated into the bottom of the cover having enlarged heads and can be removably received in the bolt slots for coupling the cover to a toilet flange when covering the opening and uncoupling from the toilet flange to facilitate accessing the opening. A handle aids in the coupling and uncoupling of the cover and a gasket is placed between the cover and flange to seal the opening when the cover is coupled to the toilet flange.

Abstract: A bristle broom is provided with a plurality of relatively flexible, soft bristles the ends of which form the majority of the broom's sweeping surface, and a smaller number of relatively inflexible, stiff bristles the ends of which form a small portion of the sweeping surface adjacent one end thereof. The stiff bristles improve the broom's sweeping efficiency in corners and edges or in removing stubborn dirt while the remainder of the bristles retain the conventional sweeping efficiency of flat bristle brooms.
