Abstract: A remote controllable toy including a plurality of passive toy units, a plurality of transmitters for remotely controlling the passive toy units, and synchronizing signal transmitting means for transmitting a synchronizing signal to the passive toy units and the transmitters. Each of the transmitters of the passive toy units transmits a control signal for controlling the corresponding passive toy unit when identifying a transmission timing allocated thereto by referring to the synchronizing signal. Each of the passive toy units receives both the synchronizing signal and the control signal, and identifies the timing allocated thereto by referring to the received synchronizing signal, so that it is actuated in accordance with the control signal received within the timing allocated thereto.

Abstract: A musical toy has a simple construction and can accurately produce melodies and rhythms without also producing extraneous mechanical noise. A generally doll-shaped body contains two permanent magnets and is fitted with a pair of swinging members each containing an electromagnetic coil disposed so that it faces the permanent magnets. A control device, containing a rhythm signal generator circuit and a control circuit which creates rhythm drive signals based on the signal from the rhythm signal generator circuit, supplies each of the coils with a separate and independent drive signal. A sound producing body is disposed in the swinging path of each swinging member so that when the swinging member is caused by the magnetic interaction between the coil and the permanent magnets to swing in response to the rhythm signal from the control device, the sound producing body is struck by the swinging member and a musical note is sounded.

Abstract: A downcomer including a tubular member oriented vertically and extending downwardly from a fluidized grid and including a lower portion provided with an inclined opening formed at a first angle with respect to the tubular member, and a flapper valve including an upper portion and a lower portion formed at a second angle with respect to the upper valve portion, the upper portion of the flapper valve is mounted pivotally to the tubular member at a position to normally place the lower portion of the flapper valve in engagement with and closing the inclined opening.

Abstract: A thermoelectric heat pump including combination adherent and metal migration barrier layers intermediate the ends of the n-type and p-type semi-conductors and the metallic electrical conductors, the layers enhance the adherence to the ends of the semiconductors and prevent migration or diffusion of metal into the semiconductors.

Abstract: Apparatus for storing and organizing spliced optical fibers into one of a plurality of in-line and butt splicing configurations and for imparting sufficiently large curvature to the curved portions of such optical fibers present during storing and organizing to prevent damage to the optical fibers, and a cover for such optical fibers upon being stored and organized.

Abstract: Pressure limiting valve for being inserted into ventilation gas apparatus which valve includes a first vent for venting ventilation gas present in the apparatus above a first pressure to provide pressurized ventilation gas delivered to a person with a peak inspiratory pressure during periods of inspiration substantially equal to the first pressure, and including a second vent for venting accumulating pressurized ventilation gas present in the apparatus from increasing above a second pressure less than the first pressure to establish a base line pressure for the pressurized breathing gas to which the person is exposed during periods between periods of inspiration.

Abstract: Doll with head turning mechanism including a pair of opposed doll heads mounted on an upper plate mounted rotatably in an upper or neck opening provided on the trunk portion of the doll. The trunk portion is provided with openable and closeable internal cavity providing apparatus. One doll head is normally exposed and the other doll head is normally received and concealed in the internal cavity. Upon the operator of the doll rotating the normally exposed head, the normally exposed head is rotated, received and concealed in the internal cavity and the normally concealed head is rotated into an exposed position. The upper plate and the cavity providing apparatus are provided with engageable members which engage upon the doll heads being reversed and prevent the upper plate from rotating and returning the doll heads to their original positions under the influence of a bias member which biases the upper plate to normally maintain the doll heads in their original positions.
