An intermittent low intensity light source that is switched on by a drive signal is enhanced by a high intensity light source. The high intensity light source is coupled with the low intensity light source so that at least some light from both sources is projected in a desired direction. The high intensity light source has a brightness or intensity that significantly exceeds that of the low intensity light source. A pulse power source is connected to the high intensity light source and made responsive to the drive signal for pulsing the high intensity light source to emit a brief light pulse before the low intensity light source achieves any substantial precentage of its peak intensity, the light pulse occurring in such close time proximity to the peak intensity of the low intensity light source that persistence of vision in the human eye causes the two light sources blend together visually.

Synchronized pulse-enhanced dual light source

An electromechanical device comprised of a battery energized motor having widely separated poles and requiring momentum for operation applied by inertia from a lost motion fly-weight accelerated by the motor during commutation which momentarily starts and stops the motor for an extended dwell time and which subsequently restarts the motor for continued operation, there being primary sensory effects as a result of motor operation subject to speed change by the control of extraneous motion, there being a first motor commutated circuit energizing sensory effects, and there being a second cam switched circuit energizing sensory effects adjusted to long and short dwell modes, the motor operation and effects being synchronous at variable angular velocity within 180.degree. and 360.degree. of rotation.

Electromechanical frequency generator-modulator kinetic storage device

Intensified light emitting diodes intermittently energized while in motion, the light emission thereof being sensed by eyesight retention as dots and bars of light dynamically related and intermixed relative one to the other in an infinite number of geometric patterns dependent upon the simple and compound application of rectilinear, arcuate and rotary motion in combination with the frequency, spacing and duration of pulse application by a flasher circuit modified by adjustment both manually and automatically.

Pseudo multi light display device and generator therefor

An inertia device which controls and produces a sensory effect as a function of a differential in the angular velocities between primary and secondary bodies rotating on a common axis with a friction drive therebetween, commutated by differential speeds of rotation, and with the sound effect functional as a result of said differential speeds of rotation, and all of which is operative through rotation of the primary body in either direction of rotation with the transfer of kinetic energy into the secondary body for control and operation of the sensory effect.

Inertial device for sight and sound effects in rotating apparatus

An electrical circuit module easily assembled by hand and especially adapted for use in a circuit package for a model includes an insulator substrate with an upper surface and a plurality of apertures extending through the substrate from the upper surface. A plurality of circuit components on the upper surface of the insulator substrate have leads extending into the apertures. A conductive eyelet extends into each aperture and is dimensioned to form a friction fit with the leads of the components and any additional connecting wires in each aperture. The circuit module may then be mounted in a base including a control panel for an electrical circuit including the module on the base. Light, sound and similar effects are generated by the circuit for a model mounted on the base.

Model with two-pole motor actuated siren and flashing lights

A simplified reversible drive especially adapted for models and toys, utilizing two parallel and spaced apart drive discs with opposing faces rotating together in tandem, a third reversibly driven disc disposed between and perpendicular to the pair of discs, and means to selectively bias the third disc against either one of the said opposing disc faces to produce selected rotation in one direction, and against the other opposing face to produce selected rotation in the other direction, all of which is easily assembled by a hobbyist, without the use of special tools, and incorporating in a light and/or sound effect producing circuit including a motor for rotating the drive discs, a background sound effect and lighting effect producing circuit element connected in series with the armature of the motor, and a normally open magnetically operated switch which is periodically closed by a magnet mounted on one of the discs to produce punctual sound effects.

Toy with reversible driven hoist

These circuits produce light, sound and similar effects in models or toys by taking advantage of current modulation produced in a commutator circuit of a two-pole motor which may be used to provide motion for at least a part of the model or toy incorporating one of the circuits. At least one additional effect-producing circuit element in addition to the motor is electrically connected to the commutator circuit. A battery or other means for applying sufficient electromotive force to the commutator for operation of the motor is electrically connected to the commutator circuit. When the additional effect-producing element is parallel to the commutator circuit, the battery supplies an insufficient amount of electromotive force to allow both the motor and the additional effect-producing circuit element to operate in their maximum current-drawing condition at the same time. A sufficient amount of electromotive force is supplied to allow either alone to operate in its maximum current-drawing condition. As a result, alternate making and breaking of connections to the commutator elements as the armature of the motor rotates produces a regular variation in the current supplied to the parallel additional effect-producing circuit element. A similar effect is produced with the additional effect-producing element in series with the commutator circuit regardless of the amount of electromotive force supplied by the battery. This modulation produces flashing or flickering of lights or sound effects, if a sound-producing element is employed as the additional effect-producing circuit element. These effects simulate the results obtainable with more complex electronic circuits.

Low cost electromechanical electronic simulation circuits

This potentiometer has a pair of insulating standoffs integrally formed with the body of a model or toy incorporating the potentiometer. An insulated trough extends between the standoffs. A resistive element wound around an insulating core is disposed in the trough. A resilient contact element is slidably mounted engagement with the resistive element. Means extends through the body of the model or toy for sliding the resilient contact element along the resistive element. This potentiometer has major portions of its assembly formed in a molding operation used to form the body of the model or toy, and can be assembled by hand without the use of special tools.
