Abstract: A clamp usable by dentists to retain a rubber dam in a depressed position so as to isolate a tooth being worked on from mouth saliva and moisture. The clamp is constituted by a bow spring whose legs are joined to jaws adapted to grip the tooth, the spring being so biased as to normally spread the jaws apart. Associated with the legs of the spring is a trigger mechanism which, when the legs of the bow spring are pressed together to cause the jaws to grip the tooth, acts to lock the jaws in this position, and at the same time to cock the trigger, the mechanism including a trigger pin passing through a hole in the yoke of the bow springs. When this pin is actuated, the jaws are immediately spread apart by the released spring tension.
Abstract: A fighting doll has a lower torso and an upper torso having freely movable arms rotatably mounted thereto. Actuating means within the doll when actuated causes the upper torso to pivot relative to the lower torso and simultaneously swings one arm upward and the other arm downward from a resting position in a fighting motion.In one embodiment, the actuating means is activated by a push button extending from the lower torso. The upper torso is pivotably secured to the lower torso and to a central shaft which is fixedly mounted to the lower torso. A stationary cup gear is positioned on the central shaft and is in communication with arm pinions secured to shafts extending from each arm. The push button has a rack formed at its end which is in communication with a pinion rotatable on the central shaft. Fixed to the pinion is a sleeve which is secured to the upper torso. By depressing the push button, the pinion and sleeve rotate on the central shaft causing the upper torso to pivot.

The bitless bridle contains novel sidepieces having a cloverleaf configuration with an eyelet at each end, and in the same plane has oppositely protruding side eyelets near one end of the sidepiece, one eyelet being slightly closer to the end than the other. The cheekstrap portion of the headstall is attached to the end eyelet nearest the side eyelets. The noseband is fixedly connected to the side protruding eyelet closest the end eyelet and the centerpiece is attached to the noseband. The chinband is attached to the oppositely protruding lower spaced eyelet and the reins are attached to the end eyelet on the other end of the sidepiece.
Abstract: Device for continuous auscultation of the motion and positions of a patient mandible including means for sensing the motion and positions of the mandible at the rear of the condyle inside the external auditory duct with the help of strain gauges connected with a Wheatstone bridge, and means for amplifying the output signal which is finally applied to a reading device. Such a device is usable for real and accurate determination of any mandibular motion, centric relation and rest position in making dental prosthesis.
Abstract: This invention relates to a method for installing a friction lock retaining pin into a tooth through the use of ultrasonic vibrations and an apparatus by which conventional ultrasonic dental scalers may be adapted for use in this method.
Abstract: A pollen collecting and trash removal apparatus for use on honey bee colonies in which bees entering from the field with pollen are forced to twist their bodies through a double screen grid with offset squares and lose the pollen pellets which fall through a hardware cloth into a pollen drawer. Bees leaving the hive with trash are forced to drop it, when they have to crawl through a 2 screen grid without offset squares, through a 1/2 inch hardware cloth into the trash drawer. The hinged lid permits easy removal of both grids for easy access of bees leaving or coming into the hive. The apparatus can remain on the hive throughout a year and still permit easy manipulation of frames in the hive. Pollen and trash drawers are removed from the side of the hive without obstruction to the normal flight of the bees. The use of hardware cloth or wire screen permits the maximum amount of ventilation.

Abstract: A beehive heater for installation between the lower brood chamber and the bottom board of a standard beehive for protecting a colony during the winter with a minimum of winter brood production and for accelerating spring brood production. The beehive heater provides an insulating curtain of heated air adjacent to the walls of the brood chambers. Air enters a plenum chamber where it is heated by a low temperature heating element and flows out of the plenum chamber through a series of holes located adjacent to the periphery of the lower brood chamber to form the insulating curtain of heated air adjacent to the walls. A landing board and entrance is provided near the upper edge of the beehive heater as means for the bees to enter and leave the lower brood chamber. The temperature of the air in the plenum chamber is thermostatically controlled with the control point adjustable so that it may be set for winter or spring operation.
Abstract: An implant is placed in the jaw of a patient by cutting spaced slots in the patients jaw and locating the side plates of a U-shaped implant in the slots. The side plates are arranged so that the healing of the jaw, by fibrogenetic and osteogenetic neoformation, results in the implant becoming anchored in the jaw, and the implant is adapted for the reception of a stump, preferably a screw threaded stump to serve as an artificial tooth on a mounting for such a tooth.
