Abstract: A permanent magnet armature is arranged to be moved initially in spaced proximity to an induction coil connected in an electric circuit across the series arrangement of a source of electric potential and an electronic switch such that when the moving magnetic field of the magnet cuts the coil turns the resulting induced current operates the switch momentarily to connect the source of electric potential across the coil. The resulting current flow through the coil produces a magnetic field which is imposed upon the moving magnet such as to accelerate its movement. An RC time constant circuit is connected across the coil to establish the time period of battery connection across the coil.

Abstract: An apparatus comprising a rocker with a curved base, and an activating base supporting and continuously activating the rocker. Two magnets, whose north poles point in opposite directions, one upward and the other downward, are respectively disposed on either side, towards which rocker rocks, of the center of gravity of the curved base. A first induction coil is set within the activating base and under the rocker so as to produce induced a current when the rocker is rocking in the direction of one of the two magnets. An operational amplifier integrated circuit (OP AMP IC) is provided within the activating base so as to amplify the induced current. A second induction coil, which is connected to the output of the OP AMP IC, is provided so as to induce a magnetic field. This magnetic field applies an attractive force on the magnet when it moves closer to the activating base, and a repelling force on the other magnet moving away from the activating base so as to activate the rocking means.

Abstract: Accessible at both sides of this toy vehicle is a shifter element that enables a user to control the vehicle using only one hand, and without picking the vehicle up or even obstructing its forward travel. The shifter element may be used to turn the vehicle on or off. If the vehicle has two or more operating modes the shifter may be used to select between the modes. The shifter thus enhances the play fantasy, since "real" vehicles start and stop without being raised from the street by their drivers. The shifter element moves transversely relative to the vehicle. In one position the element protrudes at one side of the vehicle, and if pushed inwardly there the element moves toward the other side of the vehicle. In the other position the element protrudes at the other side of the toy; if pushed inwardly it moves toward the first side.

Abstract: A motorized toy car which upon frontal impact with an obstruction simulates a crash and its consequences. The wheeled car has a chassis, a body thereon defined by a front hood section having a simulated bumper prow, an intermediate cockpit section accommodating a hinged side door, and a rear trunk section having a trunk lid hinged thereon. The intermediate and rear sections are rigid and attached to the chassis, whereas the front section is resilient and free of the chassis. Slidable along the chassis is a sled whose front end is attached to the prow, a coil spring urging the sled to a retracted position in which the front section is deformed to assume a crushed appearance. The side door and the trunk lid are operatively coupled to the sled so that swinging them from their fully open to their closed positions advances the sled against the spring to an extended position which is held by a spring-biased detent and in which the car has a normal appearance.

Abstract: A toy vehicle has a seat with a simulated seat belt in the form of two semi-circular parts which are able to rotate between an opened and closed position, the closed position simulating fastened seat belts. A power release push button is centrally positioned on the vehicle so that it does not exert any unbalanced force on the vehicle when it is pressed. When the seat belt is opened, the push button is captured in a raised position so that the vehicle cannot run. When the seat belt is closed, the capture is released from the push button so that is can be pushed. Thereafter, the push button is pushed, the power is released, and the toy vehicle is propelled.

Abstract: A toy work vehicle propelled by a bi-directional d-c motor in a forward or reverse direction depending on the polarity of battery voltage applied thereto, the vehicle including a power take-off device driven by the same motor to raise or lower a load. A gear shift mechanism operatively coupled either to the wheel axles or to the power take-off device, is controlled by a shift stick which in neutral operatively couples the motor only to the power take-off device. The shift stick is movable to a lateral position having a forward and a reverse mode in which the motor is operatively coupled to the wheel axles.

Abstract: A building block having side walls and a front face perpendicular to these is provided with two rows of coupling pins on one side of the front face and counter-coupling tubes on the other side for mechanically coupling two building blocks by means of a clamping action. In each row, each second coupling pin has an electrically conducting surface, while the coupling pins lying between these are electrically insulating. One row of conducting pins is displaced in the direction of the rows by one coupling pin from the adjacent row. On the other side of the front wall a contact bar is arranged which is connected electrically with the conducting coupling pins of an associated row. The bar has a contact area for producing electrical contact with a row of conducting coupling pins of an adjacent, coupled building block.

Abstract: A building block is provided having side walls and a top face with two rows of coupling pins on the one side of the top face and counter-coupling tubes on the other side for mechanically coupling two such building blocks by means of a clamping action. On their side faces, the coupling pins have electrically conducting regions, which extend over an angular range. The angular range of one row being turned by 180.degree. relative to those of the other row. All the conducting regions are connected to a contact bar, which is arranged on the side of the counter-coupling tubes along one side wall. When two building blocks are coupled arbitrarily, at least one conducting region of each row of coupling pins of the one building block makes contact with a contact bar of the other building block in such a way, that a short circuit cannot occur in the two electrical circuits assigned to each row of coupling pins or each contact bar.

Abstract: There is disclosed a game apparatus employing a container having located therein an electronic circuit capable of emitting a repetitive audio signal of a controllable volume and repetition rate. The container includes a compartment in which a prize or award is placed by the players. The container is then hidden by one of the players who selects the repetition rate and volume to thereby cause audio signals to propagate. The participants then attempt to locate the container in response to the emitted signals and the first participant who finds the container has access to the prize. The degree of difficulty is determined by the volume and repetition rate of the signal as controlled by the player hiding the same.
