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: A plurality of dolls are joined together in face to face relationship by attaching the extremities thereof together. The extremities are bendable to permit relative movement between each of the joined dolls. In one embodiment of the invention, the dolls are joined together in a manner to form a joint at the contiguous areas between the two dolls. In another embodiment of the invention, the legs and arms are sewn to one another and to the torso of each doll, to provide a joint at the location where each of the members are interconnected.

Abstract: A toy device comprising a hand-held manipulating handle having an opening at one end through which at least one end of a straight, round shaft can pass.

Abstract: A power transmission device for a power-operated lawn mowing machine, in which a rotational shaft for a prime mover and a rotational shaft for a cutting blade are interlocked with a friction clutch to be engaged and disengaged each other by an operating lever, and a disc brake to apply braking action to the cutting blade at the time of the clutch disengagement is provided between the movable engaging member of the clutch and a fixed member at the side of the prime mover.

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 dowel pin for removably mounting a dental model cast relative to a base cast, the dowel pin being a two-part structure to define a head portion and a shank portion extending therefrom, where the portions are threadedly engaged together in an axial alignment with each other. The head portion is adapted to be fixedly secured in the dental model cast so that the exposed end thereof is flush with a flat surface of the dental model cast. The shank portion is adapted to be removably insertable into a complimentary opening provided in the base cast, preferably with a sleeve member being provided in the opening to slidably receive the shank portion therein. The portions are selectively engageable and disengageable from each other whether or not the model cast is mounted upon the base cast. Accordingly, the dental model cast can easily be cut into segments after the head portion is secured therein.

Abstract: An animal exercising or conditioning apparatus is provided that has a rugged construction and wherein there is provided a straight-line walk. The animal conditioner or horse exerciser includes an inclined surface that keeps the horse walking up hill and shortens work out time. There is further provided a variable motor speed control and an automatic timer that turns the device off after preselected workout time, and there is also provided a loading gate that allows easy handling.

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.

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: In an index selector device of the kind for use with a stack of index cards housed between a base and a lid hinged together and having a selector on the lid to release the lid after moving card-engaging members into engagement with a card so as to raise all the cards in the stack above the one required, the selector is a plurality of push buttons, one to each card-engaging member, arranged in two rows at right angles to the hinge. Interengaging inclined surfaces on each push button and card-engaging member cause lateral sliding movement of the card-engaging member on depression of the push button. A hook on the card-engaging member moves under the edge of the card above the one required and co-operating inclined surfaces on the inner end of the card-engaging device and a central catch bar cause the catch bar to release the lid. A barb on the card-engaging member hooks into a recess on the catch bar to hold the card-engaging member in the card-engaging position while the lid is open.
