Abstract: Provided herein are continuously cast aluminum alloy products exhibiting uniform surface characteristics. The aluminum alloy products have a first surface comprising a width, wherein the first surface comprises an average of 50 exudates or less per square centimeter across the width of the first surface. Also provided herein are methods of making aluminum alloy products having improved surface characteristics. Further provided are methods and systems for manufacturing aluminum alloy products, such as sheets, having reduced surface defects.

Abstract: A carbon dioxide detector for determining the correct location of an endotracheal tube following intubation of a patient. The detector includes a housing with a first tubular member for connection to a endotracheal tube or the like, a second tubular member for connection to an anaesthetic circuit and an indicator to indicate the presence of carbon dioxide in the detector. Preferably the indicator is in the form of a transparent disc which sealingly engages an aperture in the housing, the disc having a chemical substance which provides a colour change indication when exposed to carbon dioxide from a patient.

Abstract: A dual function connector for releasable attachment to an endopharyngeal tube, airway intubator or the like. The connector comprises a cylindrical tube having a large diameter proximal portion sized to fit within an airway intubator and a distal portion with a smaller diameter than the proximal portion. Flange means are provided on the proximal portion and extend substantially normal to the longitudinal axis of the connector; and an elongated slot in the connector extends from the distal end throughout the length of the distal portion and into the proximal portion.

Abstract: This invention relates to an oro-pharyngeal airway of generally ellipsoidal cross-sectional shape adapted to function as a guide and passageway for an endotracheal tube for intubation of a human larynx having distal and proximal halves and ends in which the proximal end is generally in the shape of a cylindrical tunnel of a size sufficient to accommodate a complementary endotracheal tube and in which the distal half and end is open along its lingual surface so as to permit the passage therethrough of the aforesaid complementary endotracheal tube.

Abstract: A continuous process for the manufacture of cellular ceramic product. Ceramic feed material is transported successively through a preheat kiln section, through a foaming section whereat foaming agent mixed with the ceramic feed material is activated, and into a drawing kiln section. An elongate hollow product can be formed by drawing the foamed ceramic while soft around and past a hollow mandrel to form an elongate hollow cylindrical member.
