Abstract: An operable toy utilizes a metal sensing apparatus which includes a tuned circuit which includes a pick-up coil. The resonance frequency of the resonance circuit shifts when the pick-up coil senses a metal or magnetic object. A motor is normally driven in the absence of the sensing of a metal or magnetic object. When the metal or magnetic object is sensed, the frequency shift of the tuned circuit including the pick-up coil attenuates the frequency produced by an oscillator and as the voltage of the signal produced by the oscillator is attenuated, a level detection circuit produces a low output to thereby disconnect the power from the motor. Alternatively, the power to the motor may be reversed. Two metal sensing apparatuses may be utilized in an operable toy to cause the toy to follow a track of metallic or magnetic material.

Abstract: One problem which occurs in hydroponic growing systems is that pools of water form in the bottom of the growing bed container. These pools become depleted of oxygen very rapidly and if the plant roots extend into the pools the plants may die. This problem is solved by a false bottom (34, 54) in the growing bed container (10, 10'), so that any pooling which may occur occurs below the false bottom (34, 54). Pooling on the false bottom (34, 56) is prevented by the constructed of the false bottom (34, 56). The false bottom (34) either has a convex upper side, so that pooling cannot occur on the false bottom (34). Drainage openings (36) are provided at the two edges of the false bottom (34), so that any solution flowing towards the edges will flow through the openings (36) into the space below the false bottom (34). Or, the false bottom (56) is a sheet of formanous fabric material (56) which lies over a layer of gravel (54).

Slots can be provided in the front spherical shell wherein an artificial eyelash may be received. A forward central projection on the front half better simulates the cornea of a real eye.
Abstract: A device for maintaining a plurality of jewelry neck chains, arm or wrist chains and the like in a predetermined relationship in order to retain the jewelry chains in generally parallel, side-by-side relation thereby reducing the tendency of adjacent jewelry chains from becoming entangled with each other when being worn. In one embodiment of the invention, the device is in the form of an elongated flat bar having a plurality of apertures therein with each aperture adapted to receive a split ring clasp used to secure the ends of jewelry chains together in order to maintain the clasp and thus the ends of the jewelry chain in spaced relation to each other with the jewelry chains being maintained generally in parallel relation to each other.
Abstract: The doll of the present invention is formed by outlining a desired feature with an adhesive such as a meltable, fuser thread between a front and rear piece of fabric in an outline of the desired feature such as the nose or mouth. After the adhesive is made to hold the two sheets of fabric together, soft material is inserted between the two sheets within the feature. The outline of a nose is U-shaped, and soft material can be inserted through the top opening between the two pieces of fabric. The outline of a mouth is closed so the soft material is pushed through a slit in the rear piece of fabric. The mouth can also be formed by satin-like stitches in which long stitches are formed on the top of the front sheet of material extending from the outline of the mouth or lips. The soft material is inserted through the rear sheet to cause the front sheet and the satin stitches to bulge outward. The lips can also be formed by running stitches forming an outline, which is then filled.
