Abstract: A pair of pants or suit includes a sealable opening for relief of bodily fluids. A frame is sealed in a waterproof manner to the pair of pants or suit disposed in a groin section, the frame forming a frame aperture separating an outside and inside of the pair of pants or suit. A lid is movably connected to the frame disposed on the outside of the pair of pants or suit and configured to engage the frame aperture, wherein the lid in an open position allows access through the frame aperture and the lid in a closed position does not allow access through the frame aperture. A seal is disposed between the frame and the lid forming a waterproof closure of the frame aperture when the lid is in the closed position.

Abstract: A portable beverage container (e.g., an insulated, double-walled bottle) is disclosed. The container includes a lid pivotably connected to it by a hinge. The lid is arranged to be automatically pivoted open by the spring assembly when a catch on the lid is released so that the lid opens in a controlled, non-jarring manner. The spring assembly comprises an elastomeric member and a contact surface (e.g., a recess in a cap of the bottle). The elastomeric member is arranged to cooperate with the contact surface whereupon the elastomeric member operates bi-modally to effect the automatic opening of the lid.

Abstract: A purge gas introduction system for an orbital tube welding setup is provided, configured to inject high purity inert purge gas to the interior volume of a tube or tubular component. An o-ring is interposed between an annular base and an annular ring, their junction forming an annular o-ring groove, each part forming one sidewall, with the o-ring fully recessed within the groove, protecting the o-ring during the insertion and removal of a tube. The annular base and an annular ring are configured to receive a tube terminus. The sidewalls of the o-ring groove are divergent one to the other, wherein as the annular ring is drawn towards the annular base, the o-ring is forced partially out of the groove, forming a substantially leak tight seal between the tube and the o-ring. A purge gas from an external source is transmitted to the annular base through a purge connector, then, in turn, introduced to the interior volume of the tube.

Abstract: A filter assembly for medical and laboratory use includes a housing. The housing includes a cover comprising an inlet and a bottom part comprising an outlet. The housing also includes a plurality of spring levers distributed around the circumference of the cover. The spring levers include hook-shaped projections, the hook-shaped projections connectable with the bottom part. The filter assembly can clamp a filter membrane or media sheet between the cover and the bottom part in a fluid-tight manner.

Abstract: A wide-mouth recloseable container and cover device with a pair of two-position bails used for holding liquids, powders and like substances. The device includes a container and a cover which are cylindrical in shape. The container has a lower portion and an upper portion. The upper portion has a wide-mouth opening with a top flange disposed around the opening. The top flange has a diameter approximately the same as the diameter of the lower portion of the container. The upper portion is "necked down" to provide room for six longitudinally oriented ribs. Four of the ribs are used for supporting opposite ends of two "U" shaped bails. The two bails are used for engaging opposite sides of an upper surface of the cover for holding a lower surface of the cover against the top flange of the container. The cover has an annular recess for receiving the top flange therein.
