Abstract: A teaching and entertainment device includes a desk-top console which supports a keyboard, an LCD display matrix, and a plug-in cartridge recepticle. A quartet of LCD drivers each control a quadrant of the display under the control of a first microprocessor. A plug-in cartridge is insertable into the console and contains a second microprocessor. Apparatus are provided for establishing a master/servant relationship of the second microprocessor over the first whenever the plug-in cartridge is present.

Abstract: A toy vehicle having a motor drive mechanism with a control arm actuable from a first position to a second position for changing the speed thereof, the vehicle having a pivotable linkage arm with a cam follower coacting with a cam movable in response to vehicle travel for pivoting a trigger foot against the control arm for moving it from the first position to the second position.

Abstract: A talking figure play set comprising an environmental structure having a record player with an upwardly pointing stylus on its tone arm and a plurality of human figures or animal figures, or both, each having an open-bottom base with a phonograph record permanently recessed therein. The tone arm with its upwardly pointing stylus is recessed in a circular opening in the housing of the record player along with support means, such as a ledge or rim, for the open-bottom bases of the various figures. The phonograph record recessed in the open-bottom base of each figure has a sound recording on spiral grooves which is compatible with the appearance of the figure. When the open-bottom base of one of the figures is inserted in the circular opening in the housing of the record player, the record player is turned on to reproduce the sound recording associated with the particular figure while that figure remains stationary to allow a child to perceive the figure as a talking figure.

Abstract: The upwardly-extending reproducing stylus (100) is shielded within opening (24) in phonograph (16) when recorded-message carrier (12) is not in playing position by a cover member (246). A cam (256) unshields stylus (100) and exposes it in an arcuate slot (244) when a pin (274) on recorded-message carrier (12) exerts a downward force on cam (256) during the coupling of carrier (12) to opening (24) by engaging annular groove (290) with detents (44, 46, 48).

Abstract: A toy vehicle energizer and launcher (10) having a draw string energizing mechanism (30) with a drive spool (40) receiving a draw string (38) and a return spring (46). The drive spool (42) is connected to a toothed driving wheel (54) by a one-way clutch (67) which allows a vehicle (34) held in the launcher (10) to be energized by a number of pulls on the draw string (38). A retaining and release means (32) coacts with a drive wheel (56) of the toy vehicle (34) and a toothed driver (54) to allow the vehicle (34) to be held within the launcher (10) during energization, and to be released after energization by manual actuation of the retaining and release means (32).

Abstract: An electronic percussion synthesizer is disclosed which includes a plurality of pressure transducers, each representing a different percussive musical instrument. Each transducer is responsive to an external striking force for generating analog pulses, each pulse representing one beat of the respective musical instrument. The transducers are mounted to a synthesizer housing in a manner which mechanically isolates the transducers from each other. Each transducer is supported within a pair of housing portions by a resilient coupler maintained in compression between the interior surfaces of the housing portions.

Abstract: A unitary molding insert (24) and pin (27) of the prior art are replaced by an improved molding insert (30) which is provided with a plurality of collapsible pin assemblies (56), each including a unitary hollow, cylindrical boss (58), and a separate piston (60) having a unitary valve (62) and pin (64). Each piston (60) may be inserted in its boss (58) with its valve (62) being seated on the upper edge of the boss (58) and with its pin (64) engaging the inner surface of a mold (84) to maintain the insert (30) in a stable position during the encasing of the insert (30) with a suitable molding material. When the mold is substantially filled to capacity, the pressure created by the molding material will force the piston (60), valve (62) and pin (64) to a recessed position within the boss (58).

Abstract: An electro-mechanical display including a rotating focusing device and at least one light source. The position of the focusing device is monitored and the light source turned on under computer control to produce at a viewing position a plurality of light indications from a single source.

Abstract: A crib toy in the shape of a rocking pony having an outer shell with a downwardly facing U-shaped aperture contained therein. The U-shaped aperture contains a clamp adapted to fit over different sized crib rails to securely clamp the pony thereto. The shell contains a mechanism having an output shaft which drives a gear train for rocking the pony through a slideable connecting means, while music is also played by the mechanism.

Abstract: An electronic toy doll including electronic control circuitry responds to selection of one of a plurality of switches on the doll housing and selects associated vocal messages. The control circuitry includes a stored program of instructions and also permits a problem-solution mode of operation where the user is given a message selected by a weighted probability of the occurrence of a problem and then the doll responds according to how the user correctly or incorrectly responds to the various switch response operations possible.

Abstract: A process is disclosed for making miniature doll heads. An oversized head is formed of a shrinkable plastisol including a plasticizer, and facial features are applied to the head using a shrinkable paint. Hair is rooted to the scalp of the oversized head. The head is reduced in size by extracting the plasticizer from the plastisol. During the extraction, the head and its facial features shrink simultaneously to form the miniature head.
