Abstract: A swim fin assembly of a generally T-shaped configuration including a flexible fin and an elongated foot support bar traversing and being operatively connected to the fin in a rigid securement. The fin is progressively more flexible from its forward end to its rearward end and from its upper and lower edges toward its center. A pair of foot receiving members are pivotally mounted on the foot support bar proximate its extended ends such that upon securing one's feet in the foot receiving members the fin is substantially perpendicular with respect to the wearer's feet such that upon exerting a stepping-type motion employing alternating thrusts in a prone position in a body of water, the resulting reciprocal pivotal movement of the foot support bar about its midpoint causes the vertically oriented fin to move from side-to-side and propel the wearer through the water.

Abstract: A steering stabilizer apparatus for connection with the steering components of a knee action type vehicle front wheel suspension system which biases the steerable wheels toward a straight forward neutral position.

Abstract: A carbon dioxide absorption canister is used with a closed circuit or circle analgesia apparatus, including a gas supply machine, a face mask for the patient, and inhalation and exhalation conduits. The carbon dioxide absorption canister is operatively coupled to both the gas supply machine and the face mask. The canister is composed of a container having a cylindrically shaped side wall with an integral bottom and a removable lid. Both the container and the lid are composed of a synthetic, transparent, resinous material such as an acrylic resin. The gas inlet from the patient to the canister is located at the bottom and contains a check valve that allows flow only into the canister through the inlet. An absorption medium support tray, positioned in the container and spaced above the bottom of the container, supports a quantity of absorption medium, such as soda lime.
