Abstract: A firearm with a slide and a frame. The slide has a slide rail. The frame has a frame rail. The frame rail interfaces with the slide rail. The frame rail has a lubrication groove and a debris removal port. The lubrication groove extends along a surface of the frame rail that bears against the slide rail during operation of the firearm. The debris removal port has gap within the frame rail proximate to an end of the lubrication groove.

Abstract: Aspects of the disclosure relate to prosthetic valves having a frame, a frame cover, and a leaflet construct. Some aspects are directed to a diametric taper for the prosthetic valve for achieving enhanced performance of the prosthetic valve under operational conditions, enhanced compressibility and delivery characteristics, and other additional or alternative advantages. Other aspects are directed toward unique assembly and attachment methods for securing leaflet constructs to support structures. Other aspects are directed toward features for interacting with transcatheter delivery systems. Still other aspects are directed to such apparatuses, systems, and methods for valve replacement, such as cardiac valve replacement.

Abstract: Embodiments described and discussed herein generally relate to resonators for pressurized fluid systems, pressurized fluid systems containing resonators, and methods of reducing acoustic energy within pressurized fluid systems. In one or more embodiments, a resonator includes a first chamber containing an inlet and an outlet, a second chamber containing an inlet, an outlet, and a passageway, where the inlet of the second chamber is in fluid communication with the outlet of the first chamber, a third chamber containing an inlet and an outlet, where the inlet of the third chamber is in fluid communication with the outlet of the second chamber, and where the outlet of the third chamber is configured to be in fluid communication with a pressure relief device containing a safety valve, and a fourth chamber in fluid communication with the second chamber by the passageway.

Abstract: A washable utensil storage assembly and method of constructing the assembly includes a body comprising a plurality of walls and at least one shelf for locating a holding assembly for supporting utensils. The body further comprises a cavity formed by the plurality of walls that is enclosed by the at least one shelf at a first end and a removably positioned panel at a second end spaced from the first end.

Abstract: The present invention comprises a novel lighting panel and outlet strip suitable for mounting underneath cabinetry or similar locations of low clearances or limited natural illumination. The panel has an illuminating assembly housed within a transparent or translucent cover as well as an outlet strip for electrical appliances, most preferably consisting of a Ground Fault Interrupter (GFI) electrical outlet.

Abstract: A utensil holder for particular, but not exclusive, use in a kitchen environment in which a swivel block is formed with a series of utensil receiving slots. The utensil holder is readily mounted to both horizontally and vertically disposed surfaces by means of a swivel assembly which permits rotation of the utensil holder to a variety of orientations once so mounted.

Abstract: A sleeve which is slid over the blade of a knife or the like and includes two interconnected sections. One of the sections includes a plurality of spaced molded clips formed in and spaced along a shoulder which extends around the periphery of the one section. The other section includes a plurality of cut-outs formed in and spaced along a shoulder which extends around the periphery of the other section. The clips on the one section extend through the openings defined by the cut-outs in the other section respectively and latch onto the shoulder on the other section for coupling the first and second sections together to form the sleeve.

Abstract: Rubber charge roller cores are coated with loose particulate silicon carbide. Excess powder is removed, and the rollers are used in normal operation without an additional outer layer. Consistent, long-life operation of the charge roller is realized.

Abstract: An improved electrophotographic printer is provided in which the voltage applied to the charge roller is automatically adjusted to compensate for its changing characteristics over its life span. A high voltage DC power supply includes an output that is connected to the charge roller, and the input side of this high voltage DC power supply is controlled by a microprocessor of the print engine. The print engine controls the output voltage of the high voltage DC power supply by changing the duty cycle of the pulse-width modulated control signal that is supplied to the input of the high voltage DC power supply. A look-up table contains the correct duty cycle for the pulse-width modulated control signal with respect to the number of prints that have been made. The result of the inspection of the look-up table is used by the microprocessor of the print engine to control the correct duty cycle for the pulse-width modulated signal.
