Abstract: A method of retaining dentures in position by use of magnets. A first magnet element is mounted to a support associated with a person's jawbone, such magnet element being exposed at or above the gingival margin of the person's gum, and a second magnet element is located in the denture. The second magnet element aligns with and abuts the first magnet element when the denture is fitted to the patient. Retention is achieved by way of magnetic attraction between the first and second magnet elements, one at least of which is a magnet that exhibits a magnetic field.

Abstract: Remote radio controlled inflatable toy includes a huge inflatable figure of man, animal or object, a movable base connected to the bottom of the figure and operable by remote control of a radio signal, and a separately provided radio signal emitter/controller. Wheels radio signal receiver and drive mechanism are provided under the movable base to drive and/or change direction of movement through the remote control of the radio signal emitter/controller. A connector is provided on top of the base to retain the inflated figure and keep the figure from falling from the base. The static figure is removably mounted on the base through inflation to cause its bottom or foot to be urged against the connector or retracted therefrom. The radio controlled base adds a dynamic interest to the static figure mounted thereupon. When the figure is separated from the base, both can be played with as individual items. A plurality of figures can be provided interchangeably on a single base.

The game call is formed by the cooperation of a top portion and a bottom portion which when placed together form the two air chambers and mouthpiece with a common wall separating the two chambers.

Abstract: The present invention relates to a device which uses a trigger and pistol grip wherein the trigger has a gripping side adapted to receive a finger and an opening rearward of the gripping side which is substantially parallel to the grip. The trigger is covered by a guard made of a smooth material which covers the opening so that the guard contacts a portion of the hand holding the grip and urges the portion of the hand out from between the trigger and the grip.

Abstract: A robot doll made up of a plurality of diverse shaped pieces wherein each pair of pieces are joined together by a press fit joint is disclosed. The pieces that make up the body and limbs of the robot doll are jointed for articulate movement. Each arm features a pair of parallel jointed extensions mounted for articulate movement to a main shoulder piece that is attached to the body piece. The parallel jointed extensions are adapted for grasping a missile launcher. The arms of the robot doll are formed from pieces that become the trunk and leg portions of a smaller toy doll. Small heads and small articulated arms are provided and may be attached by stub-cup joints to the trunk portion of the toy doll, thus converting the robot arm into a smaller toy doll. The trunk portion of the robot doll is formed so that it can be used as the main body portion of a toy airplane. Pieces such as wings, a nose, and tail portion are provided and can be attached to the trunk by press fit joints to form an airplane.

Abstract: An aerodynamic toy is provided with a circular central portion having a center surrounded by a substantially flat circular surface, a rim circumscribing the circular central portion terminating in a given plane, a surface of curvature extending from the flat circular surface and curving downwardly to the rim to form an outer convex surface and an inner concave surface and a lip concentric with the rim and extending from the inner concave surface and terminating before the given plane.

Abstract: A two-part stress-reliever employs a first member supporting an upright flange and a second member bifurcated and straddling said flange. An elongated slot in the flange receives a pass-through pivot pin carried by the second member and said slot also includes a resilient body biasing the pivot pin to its normal unstressed position in said slot.

Abstract: Vapor hood for covering the head of the user for enabling water vapor to surround the user's head freely and penetrate the user's hair equally during hair treatment is disclosed for use with a sink including a hot water faucet. The vapor hood is formed from a self-supporting, vapor impervious, non-flexible, dome shaped member including a head opening allowing placement of the head of the user within the interior of the dome shaped member. The dome shaped member has dimensions such that the water vapor can freely surround the head of the user located within the interior of the dome shaped member. The vapor hood can further include a flexible, impervious member removably attached to and around the base of the dome shaped member for vaporously sealing the base of the dome shaped member with the sink.

In one embodiment, a toy tank truck has a rotatable tank portion which includes an outer cylindrical wall and an inner cylindrical wall spaced from the outer wall to define a limited volume of space. A liquid reservoir is mounted on a portion of the outer wall whereby the reservoir may be above the limited volume of space in a fill position and below the limited volume of space in a drain position, upon rotation of the tank. Several reservoirs may be provided and each reservoir can include scoops to facilitate storage of the liquid in the reservoir.

Abstract: Orthodontic brackets are adhered to the surface of tooth enamel by activating the surface of an adhesive patch and applying the activated surface to the enamel. The adhesive patch may be preformulated and prefabricated into a solid film sandwiched between easy release protective liners and the film can be applied to the bracket by surface activation as discussed above. The invention also includes removal of the bracket by a deactivation of the surface of the adhesive patch.

Abstract: Apparatus for securing a denture plate in position is disclosed. The illustrated and preferred embodiment incorporates a vacuum pump which has the exterior form and shape of a tooth embedded in a denture plate. The tooth incorporates a reciprocally operated pump. The pump pulls air from an exposed, lower indention or chamber. This chamber is connected via multiple passages to similar chambers around the denture, all of the chambers collectively open to the gum of the wearer. As air is evacuated from the chambers, a vacuum is formed. The vacuum increases holding power of the denture against the gum.

Abstract: This invention relates to an improved tooth elevator characterized by a bit terminating in a blade having a generally S-shaped or reverse S-shaped cross section. The invention also encompasses the novel method of extracting at least one of a pair of adjacent teeth with an elevator having an S-shaped or reverse S-shaped tip which consists of inserting the bit with its axis essentially horizontal in between the teeth to be extracted and rotating said bit about its axis in a direction such that a remote sharpened edge of the S-curve engages one of said teeth at a point spaced from the gum line defining a fulcrum about which the adjacent sharpened edge of the S-curve pivots into prying engagement with the other tooth of the pair nearer said gumline so as to lift the latter out of its socket.

Abstract: A pair of spaced apart grooves are machined in a plate in correspondence with the movement of a patient's left and right condyles relative to the sockets in which they move. A third groove is also machined in the same plate, equally spaced and remote from the pair of grooves, in correspondence with the minimal separation of the patient's mandibular and maxillary teeth at various lateral and anterior positions. The plate is then attached to a cast of the patient's maxillary teeth and is mounted in an articulator frame on rigid posts which slide in the machined grooves of the plate as the plate is manually moved, thereby reproducing movements corresponding to the patient's closure pathway and condylar topography.

Abstract: A toy has an elongate body dimensioned to be held in the hand. A whistle or reed responsive to the passing of air to produce a sound is positioned at at least one end of the elongate body. Throwing the body through the air produces a sound.
