Abstract: Described herein is a cordierite membrane coated on a monolith substrate formed from cordierite. The membrane coating is formed from cordierite particles which have been processed to have a median particle size diameter of between 1 and 3 microns with a narrow particle size distribution suitable for forming a cordierite membrane on a cordierite monolith substrate. After the cordierite membrane is formed on the cordierite monolith substrate, the cordierite membrane monolith has a pore size of less than 1 micron.

Abstract: An adjustable mask system (100) includes a cushion with a seal (130) having the ability to change size and/or shape. The seal is preferably a one-piece, continuous member without interruptions. To effect adjustment of the size and/or shape of the seal, an actuator may be provided, which may take the form of a dial (190).

Abstract: The present disclosure relates to oral care compositions. In particular, the present disclosure relates to oral care compositions comprising sucralose and sodium saccharin, while being substantially free of other sugars or sugar alcohols.

Abstract: The present invention is a semi-automatic pistol receiver assembly comprising multiple removable parts rather than single piece construction normally used in semi-automatic pistols.

Abstract: Pistols have a body having a grip, the grip defining an elongated magazine passage adapted to receive a magazine and defining a magazine axis, the grip having opposed left and right side walls and a front portion and an opposed rear portion, the body having an upper portion having a first linear interface element aligned with an attachment axis offset from the magazine axis, and a removable backstrap element adapted to overlay the rear portion of the grip and having a second linear interface element adapted to removably connect to the first linear interface element. The pistol frame may include slide rails defining a slide plane, and the first linear interface element may be parallel to the slide plane. The first linear interface element and the second linear interface element may comprise a sliding interface. The sliding interface may be a dovetail feature.

Abstract: Pistols have a body having a grip, the grip defining a magazine passage adapted to receive a magazine, the grip having opposed left and right side walls and a front portion and an opposed rear portion, the front portion of the grip including a first front strap attachment facility, a front strap element having a second front strap attachment facility adapted to removably connect to the first front strap attachment facility, and the front portion of the grip defining a front path and the front strap element being an elongated element movable along the front path, such that the front strap element is removable for replacement by an alternate front strap element. A funnel element may be adapted for connection to the frame at a lower rim of the grip at an installed position.

Abstract: Pistols have a body having a grip, the grip defining a magazine passage, the body having a trigger guard defining a trigger space, the body having an upper surface, the body having a first mounting facility, an upper frame assembly removably connected to the body in a connected position, the upper frame assembly including a trigger element extending into the trigger space when in the connected position, a protrusion extending upward from the upper surface of the body, the protrusion having a forward-facing first bearing surface, and the upper frame assembly having a rear-facing second bearing surface adapted to abut the first bearing surface when in the connected position to transmit recoil forces from the upper frame assembly to the body. The upper frame assembly may have a slide rail. The upper frame assembly may define a horizontal slide plane.

Abstract: A patient interface system for delivering a flow of breathable gas to a patient includes a patient interface structure configured to sealingly engage the face of the patient and a retaining element configured for application to the patient. The retaining element is configured to support the patient interface structure in sealing engagement with the face of the patient. The retaining element includes an adhesive and/or at least one strap. In addition, the patient interface structure is configured to be released from and re-engaged with the retaining element for re-positioning of the patient interface structure relative to the patient's face in a plurality of positions while the retaining element remains supported by the patient.

Abstract: A mask system for delivery of respiratory therapy to a patient includes a nares portion and a mouth portion and an inlet conduit connected to at least one of the nares portion and the mouth portion to deliver the pressurized, breathable gas. The mask system is adapted to selectively utilize the nares portion and/or the mouth portion in a first mode utilizing both the nares portion and the mouth portion, and in a second mode utilizing the nares portion and not utilizing the mouth portion.

Abstract: A decocking safety lever for use with an external hammer shotgun includes a safety rod selectively positionable between a safe position wherein squeezing of the trigger is prevented; a fire position wherein squeezing of the trigger fires a shotgun shell; and a decocked positioned wherein the hammer is positioned in a decocked position and unable to fire the shotgun shell.

Abstract: A patient interface is configured to deliver a flow of pressurized breathable gas to a patient's airways. The patient interface includes a central portion with an opening configured to deliver the pressurized breathable gas to the patient's nares. A first stabilizing portion extends from the central portion and is structured to engage an outer side of a respective one of the patient's nostrils. A second stabilizing portion is opposite the first stabilizing portion and extends from the central portion. In addition, the second stabilizing surface is structured to engage an outer side of a respective one of the patient's nostrils. The central portion, the first stabilizing portion and the second stabilizing portion cooperate to form a U-shape configured to cradle the patient's nose so that the tip of the patient's nose remains exposed when the patient interface is mounted on the patient's face.

Abstract: An elbow for a respiratory mask includes a mask connection end adapted to connect to the mask and a tube connection end adapted to connect to an air delivery tube that delivers breathable gas to a patient. The mask connection end includes a first region constructed of a more rigid material and a second region constructed of a more flexible material. The second region provides flexibility to one or more portions of the mask connection end to enable engagement and disengagement of the elbow with the mask and/or sealing of the elbow with the mask.

Abstract: A mask system including a headgear and cushion module and a seal and frame module provided to the headgear and cushion module. The seal and frame module includes a sealing portion adapted to form a seal with the patient's face and a frame portion adapted to form a breathing chamber. The headgear and cushion module includes a cushion region adapted to support and shape the sealing portion and a headgear region adapted to support and stabilize the mask system on the patient's face.
