Abstract: A dart game target having a base on which is assembled a plurality of individual, relatively movable target members separated from one another by a frame having thin ribs interposed between adjacent members. The target members are yieldably biased in a direction away from the base. Movement of the members in a direction away from the base is limited by laterally extending projections carried by the target members which underlie the inner surfaces of the ribs. The arrangement is such that no part of any rib overlies any exposed part of any target member. Warping of the frame or of the base is compensated for by protrusions on selected ones of the ribs which extend in a direction toward the base.

Abstract: This disclosure is directed to an improved laryngoscope blade sheath for use in the intubation process to maximize laryngoscope use by providing a single unit to orchestrate the laryngescope and the endotracheal tube. This invention is a sterile, disposable, generally linguiform laryngoscope blade sheath. The sheath is made mostly from a fairly rigid material. The inside of the sheath is hollow so that all the common standard laryngoscope blades can be inserted through its aperture. The width of the sheath is wider than the common blades and the shape of the sheath is curved and spoon-like so that the tongue can be lifted stably without slipping. There are orifices on the underneath surface of the sheath so that the light of the laryngoscope blade can shine through these orifices and the trachea can be visualized. The sheath also has an intubation guide groove underneath to make intubation more efficent. Because this sheath is used only once there is no danger of cross infection.

Abstract: There is disclosed a method for effecting cardio-valve replacement surgery. A clamp adapted to be fastened to an ether screen has multiple arms. These arms are linked together by a double clamp having two parts which are pivotable with respect to each other and within which the arms are both rotatable and slidable and which arms are simultaneously clamped in whatever position they may have been set. The clamping is effected by a draw bolt passing through both parts of the double clamp. At the free end of the arms is a clamp adapted to hold a replacement cardio-valve holder. The clamps and the arms are adjusted to present a replacement valve in a position such that it can be sutured into the heart of the patient without the surgeon having concern about the possibility of malalignment of the valve or suturing.

Abstract: An apparatus for simulating the coaching career of a collegiate football coach. The game simulates factors encountered by a coach whose long term objective is to advance his career from coaching at a minor level team to a higher level team. The game utilizes a game board having an inside track and an outside track. The inside track is a recruiting season track which simulates the conditions involved in recruiting the best available players. The outside track is a playing season track where the coaches try to defeat other teams. The game begins by first moving pieces representing coaches along the inside track recruiting players during the first recruiting season and then proceeding to the first playing season on the outside track. A coaching year represents one lap around the recruiting season track and one lap around the playing season track. The game board and related pieces cooperate to give successful recruiting coaches a higher probability of achieving a successful playing season.

Abstract: A method and device for the prevention of and the treatment for epicondylalgia externa, popularly known as tennis elbow. The method involves the absorption and dissipation of the vibrational shocks caused by the off-center hitting of a tennis ball during pronation and supination of the wrist. The device employs a vibration absorbing pad covering either the extensor or flexor muscles of the forearm. The pad is tightly located against the said muscles by means of an elastic tube from the wrist area to the elbow. An elastic strap, located outside the aforementioned tube around the largest diameter of the forearm and fastened by velcro or like fasteners, is an additional member for maintaining the pad in close contact with the arm surface. The aforementioned pad, shaped to conform with the extensor or flexor muscle in the forearm, is filled with a viscous fluid or semi-fluid which will flow enough to maintain a close contact with the muscle from wrist to elbow.
