Abstract: A particulate filter particularly suited for analytical gravimetric weighing applications is disclosed. The particulate filter includes a polytetrafluoroethylene (PTFE) media supported by a ring and yields stable microgram and submicrogram weighing results. The support ring may be PTFE, metal foil, or another non-hygroscopic polymer such that the mass of the filter does not vary with changes in atmospheric moisture. The filter simplifies the discharge of electrostatic charge buildup such that when a conductive filter media is combined with a conductive ring device, the discharge may be accomplished by placing the filter on a grounded weighing pan or other surface. The particulate filter can simplify filter identification by including identification symbols imprinted on each side of the filter media.

Abstract: The present invention relates to hearing aid microphone covers and methods of manufacturing the same. In an embodiment, the invention includes a microphone cover for a hearing aid including a frame defining one or more exterior apertures and one or more media apertures, and a filtration media attached to the frame, the filtration media configured to completely occlude the one or more exterior apertures. In an embodiment, the invention includes a method of forming a microphone cover for a hearing aid including placing oleophobic and hydrophobic filtration media within a mold and forming a polymeric frame around the filtration media by injecting a polymer composition into the mold.

Abstract: An off-road in-line skate which includes a plurality of wheels mounted to a frame of a skate where the wheels each have a diameter in the range of 40 to 60% of the length of a boot of the skate to provide a maximum wheel diameter to clear obstructions while presenting an overall wheel base length less than a maximum wheel base length which would otherwise cause tripping during cross-over skating.

Abstract: A braking apparatus is provided for a skate which comprises a shoe composed of at least one quarter connected to a shell associated with a supporting frame for a plurality of wheels. The braking apparatus includes a braking element connected to a rear portion of the supporting frame adjacent the wheels. A brake arm is connected between the quarter of the skate and the braking element. The brake arm includes a first member and a second member connected together with the first member moveable with respect to the second member. The brake arm includes a switch mechanism operable between a first and second position. Upon activation of the switch mechanism from the first position to the second position, the first member of the brake arm moves away from the second member of the brake arm such that the length of the brake arm is increased and the braking element is positioned lower with respect to the wheels of the skate.

Abstract: An in-line skate is disclosed having a frame with a plurality of wheels and a boot coupled to the frame. The boot has a cuff and lower shell connected by a resilient connecting member that permits flexing along substantially the entire length of the member. The connecting member can be made of spring steel or a variety of synthetic materials.

Abstract: An in-line skate has a fastening system which includes a strap having a first end and a second end each secured to a same side of the skate. A buckle is provided for releasably securing one of the first and second ends to the side. A first fastening member is secured to the strap at a point between the first and second ends. A second fastening member is secured to the boot on a side opposite the side on which the strap ends are fastened. The first and second fastening members may be releasably joined and tensioned.

Abstract: A portable, high-pressure, power washing system is described which includes an electric motor driven gear pump where the electric motor is effectively water cooled by virtue of being contained in a thermally conductive housing surrounded by an insulating water jacket through which the water being pumped is made to flow before reaching the pump's inlet port. The pump is driven through a gear reduction mechanism such that a relatively inexpensive, single-phase, series AC (universal) motor normally operating at a high rpm can be employed. By proper dimensioning of the pump chamber relative to the drive and idler gears and by providing a flow divider at the pump chamber's discharge orifice, high pumping efficiency is obtained. Completing the assembly is a discharge wand for directing the high pressure water at the surface to be cleaned and for controlling the on/off state of the pump's drive motor.

Abstract: A pressure cooker for use in microwave ovens includes a microwave permeable bowl shaped container, a microwave permeable dome cover, and a steel locking ring permanently attached to the cover for maintaining the container and cover in fluid-tight seal during use. A safety valve, formed of flexible tubing, encounters a projection of the container and is deformed into a closed configuration responsive to movement of the cover, relative to the container, toward a locking position. A pressure regulator valve, consisting of a metal core surrounded by an elastically deformable casing, is positioned over a pressure control opening in the cover to maintain a selected operating pressure level in the pressure cooker. A pressure indicator and relief assembly, contained in a pressure release opening through the cover, indicates positive pressure in the chamber and is ejected in the event of an abnormally high pressure inside the housing.

Abstract: A device for rotating food while cooked in a microwave oven includes a metal housing supported above the oven floor by dielectric feet, and a turntable mounted above the housing. The turntable is rotatable by virtue of a turntable shaft having downwardly extended legs forming a non-circular cross-section, insertable into a similarly configured bore within a drive shaft inside the housing. A detent, pivotally mounted beneath the housing, can be pivoted manually to a locking position in which an arm of the detent engages one of several notches formed in the turntable, to prevent further turntable rotation relative to the housing. A bearing assembly between the top of the housing and the turntable includes an annular frame, and a plurality of ball bearing-containing receptacles arranged symmetrically about the frame.
