Abstract: A ball bat having a bat handle, a handle end of the bat, a bat head, a center of gravity and weights on the bat handle end for offsetting the center of gravity in the direction of the handle end. The bat also may have grooves in the bat wall to lighten the bat head, and an inward projecting acorn-shaped weight at the handle end.

Abstract: A laryngoscope (1) is equipped with a dynamometer in order to be able to measure and record the force expended per unit time by an anesthetist during the vacating and keeping unobstructed of a path in the oral and pharyngeal cavity for the introduction of a tube into the trachea. The dynamometer comprises pressure elements arranged in the spatula contact surface (17) and, respectively, in the proximity of the spatula joint. By means of this measurement, an objective judgement can be made with regard to the anesthetist's skill; on the other hand, the pharmaceuticals utilized for the intubation procedure can be objectively documented by measured values with regard to their pharmacological properties, such as, for example, the production of rapid and intense muscle relaxation.

Abstract: A disposable cone channel insertion probe is adapted for use in combination with an infrared thermometer. The probe has a generally frusto-conical hollow body portion, an inner reflective surface, and a flange projecting radially outward from the rearward end of the probe. The infrared thermometer also includes a mechanism for retaining the probe and optics for further focusing and collimating the infrared light from the probe to an infrared sensor.

Abstract: The apparatus includes a basin with a 10-50 cm depth preferably 20 cm and at least a metal halide high pressure lamp (MeH), a mercury high pressure lamp (HgH) or a mercury low pressure lamp (HgN) with filters. The lamps have a spectral range of 290 to 400 nm and are arranged to illuminate prone support surfaces. The bath tub may be made of an acid resistant material, preferably a synthetic plastic. A fixed or removable plastic prone support surface in the tub bottom and a liquid inlet and outlet for circulation of the solution for processing and storage are provided. The outlet is connected to the inlet through a filter device, a processing tank, a thermally insulated storage tank, a thermostatically controlled flow heater and a pumping device. A radiation source may be located under the prone support surface.

Abstract: An improved ball bat for hitting and fielding practice comprising an elongate bat having at least one depressed ball holder disposed on said bat distal the handle thereof for temporarily holding a ball for hitting.

Abstract: A method of enhancing the well-being of a living creature, wherein energy from a laser light-source bombards a target area on the skin or hide of the living creature, a short-pulsed laser light source is disposed remote from the target area and produces an elevated emergence energy density so that its radiation, for a short duration, applies a high output per unit area to the target area.

Abstract: A method and apparatus for cooling the extracranial area including the face and, optionally, also including the mandible, during emergency care of cardiac arrest or severe shock; the method is preferably implemented by means of a head cooling apparatus which includes a watertight shroud for the head and which needs no refrigeration. The head cooling apparatus contains the unreacted constituents of an endothermic reaction, such as pellets of ammonium nitrate (NH.sub.4 NO.sub.3) stored adjacent a selectively avaiable reservoir of water, and thus needs no external coolants or refrigeration. Preferably, the head-cooling apparatus comprises a portable, self-contained system which is suitable for storage, transport and/or use anywhere.

Abstract: A thermal vascular dilating device including a cylindrical shaped water tight container with the center opening sufficient to allow the arm to fit through preferably with a lengthwise cut held together with VELCRO straps and a length long enough to interfit over the hand with a VELCRO strap closure to fold the device over the hand with a threaded spout and cap opening for filling the container with warm water.

Abstract: A tossing game is disclosed which utilizes a pair of target areas or trays placed on the ground at a desired distance from one another. Each of the target areas or trays has a plurality of cups of varying heights. The players toss projectiles (preferably disks) from a position adjacent one of the target areas to the other. Points are scored by landing a projectile either on the tray or in one of the cups, with the number of points increasing when the projectile lands in the taller ones of the cups.

Abstract: Thermotherapy apparatus used for performing a thermotherapy for a diseased part of a tumor such as a cancer of a living body. A heating portion is arranged in a distal end portion at the body cavity side of a probe which can be inserted in the body cavity through an endoscope or the like or a distal end portion at the body cavity side of an insertion portion of the endoscope. The heating portion has a far-infrared radiation ceramic member, and a heater for heating the far-infrared radiation ceramic member.

Abstract: A sternal retractor for use in internal mammary artery dissection comprises a rack bar having fixed and movable spreader arms, the blade-carrying parts of which are rotatable to, and lockable in, several discrete positions. The blades are carried by slides on the spreader arms, and are pivotable about two mutually perpendicular axes which are also perpendicular to the arms, but restrained against rotation about axes extending lengthwise of the arms. One of the slides disclosed is provided with an undercut slot to receive a post for mounting auxiliary retractors. This makes the retractor especially useful for various operation in addition to internal mammary artery dissection.

Abstract: A two way soccer goal is disclosed which includes a framework holding a net within it. The goal is joined together in such a way as to allow the framework and net to remain joined even as the goal is disassembled for storage or transporting. The end posts of the framework are open at the bottom ends, thus allowing them to be placed over the two stakes placed into the ground. The two way feature allows the game to be played in a small area by placing the goal in the center of the playing area. One side is the goal of one team, and the opposite side is the goal of the opposing team.
