Abstract: A system for delivering oxygen to a substantially stationary patient without coupling a device to the body of the patient is disclosed. The system includes a source of oxygen coupled to a delivery system wherein the delivery system has a pump configured to pressurize oxygen and an elongate hollow member operatively coupled to the pump. The elongate hollow member has a proximal end and a distal end and is constructed to receive oxygen in its proximal end and deliver oxygen to the patient out the distal end. The length and diameter of the elongate member, the flow of oxygen through the elongate member, and the distance from the distal end of the elongate member to the face of the patient are optimized to collimate a stream of oxygen such that when the stream of oxygen reaches the patients face it envelops the face of the patient.

Abstract: A spring system comprising flat plate-springs with one end mounted rigidly to an un-spring first base and the opposite end mounted rigidly to a sprung second base. The spring system is fitted with cams as strain-control surfaces, mounted tangent to the plate springs and spaced progressively from the said plate-springs beginning at the tangency. The strain-control cams are movable to provide for adjustable spring rates, actively repositioned upon demand therein providing an adaptive active spring-rate system or suspension.

Abstract: A tube cutting machine comprises a tube secured in a chuck tightened against an outer tube wall and by a mandrel expanded within the tube against the tube inner wall opposite the chuck. A blade with a conical body side on the tube body side advances into the tube at the body side angle, eliminating longitudinal force against the tube body and accumulation of tube material on the blade body side. In alternative embodiments, either the tube or the blade can rotate. As the blade edge enters the tube wall, the blade end side, opposite the body side is also conical and pushes the tube cut portion longitudinally away from the tube body, causing the tube before the blade to neck under the longitudinal force imposed by the blade end side. The blade is reversed when the neck weakens and is unable support the tube cut portion but has not yet broken, referred to as the failure point. The blade is then withdrawn and the neck is snapped off. The failure point is detected by a rod urged transversely against the tube end.

Abstract: An icing dispenser having an expandable elastic reservoir on the handle proximal end which when loaded expands a reservoir bladder under an elastic bias that tends to return the bladder to its unexpanded condition, therein uniformly impressing constant pressure on the icing within the reservoir. A reservoir neck extends from the bladder through a handle passageway to a decorator icing tip. A butterfly valve within the reservoir neck modulates an amount of icing flowing through the tip with butterfly ends angled parallel to the passageway and urged into the pliable neck at a preferred angle, slightly deforming the neck to effect a valve seal. The handle is adapted for operation in an operator's fingers as a writing instrument with icing extrusion modulated by a lever on the handle being adjusted relative to the handle by the fingers.

Abstract: An apparatus for adjusting the position of a handlebar on a bicycle or the like having a base member, an upper link, a lower link, and a intermediate member forming a parallelogram type link. A protrusion formed on the lower link extends into and slidably contacts a tracking slot formed in the upper link. A locking means for fixing the upper and lower links has a locking pin disposed in a bore formed in the upper link and extending through one of a plurality of holes formed in the protrusion of the lower link. The locking pin defines a locked position when extending into one of the plurality of holes and an unlocked position when released. The pin is biased in the locked position. A release lever is disposed on the upper link having a operating portion for grasping by a rider and a locking pin portion for engaging the locking pin.

Abstract: This invention describes a machine for the manufacture of small grooves in metal edge inserts typically found on the undersurface of snow skis. The machine produces ice-cutting blades by cutting grooves of approximate uniform depth a constant distance from the edge of the snow ski. With a ski positioned and secured with mounting clamps 21 so that a metal ski edge extends beyond a machine platten 10, a plurality of flattening clamps 23 flatten the typically bowed ski against a flat undersurface 22 of the machine platten 10. A cutting tool on a tool holder slidably mounted to a slide means on the platten upper surface then cuts into the metal ski edge following the curvature of the ski edge as it traverses the ski.

Abstract: A snow ski with one or more small grooves near the undersurface edges, with or without edge inserts typically found on the undersurface of snow skis. The grooves are designed to facilitate rapid and precise maneuvering through snow or ice surfaces. The grooves, formed parallel to the ski edge, are relatively short, nominally between 5 centimeters to 45 centimeters in length, to minimize any tendency for a ski with grooves to track in a straight line. They are typically located near the edge of the ski undersurface and longitudinally under the boot attachment position of the uppersurface. The grooves can be of various shapes designed to optimize the cutting affect of the groove as it complements the cutting of the sharp ski edge during turning maneuvers in the usual manner of skiing. The ski undersurface can be beveled at its side to reduce any increase in drag during straight skiing that may be caused by adding grooves to the undersurface.
