Abstract: A digitally driven audio effects generator includes a source of binary information and keyboard which provide digital information to a plurality of source or sink type binary drivers. A ladder matrix is coupled to the binary drivers and provides an output signal. An audio frequency signal generator responds to the keyboard and controls an interrupting switch which serrates the output signal at an audio frequency rate.

Abstract: A hand held, hand operated hair braiding apparatus having a plurality of aligned gear members, each having an aperture therethrough for passage therethrough of a strand of hair, with a first pair of adjacent gear members having the positions interchanged in response to actuation of a lever member in a first direction with the remaining gear member then being interchanged with the adjacent one in response to pivoting of the lever member in the reverse direction. There is also disclosed an accessory device for facilitating the use of the hair braiding apparatus.

Abstract: A toy vehicle (12) including a tractor (14) and a semi-trailer (16) is steered by a steering wheel (84) rotatably mounted to the semi-trailer (16) and linked to the rear end of the tractor (14) laterally of its 5th wheel pivot (52) by a rod (88) which swings the tractor (14) about the pivot (52) when the steering wheel (84) is rotated.

Abstract: A spiral-type ore concentrating wheel has a plurality of interleaved, spiral bands tapering in height uniformly from the periphery of the wheel to its central, discharge aperture for moving concentrates to the aperture while the wheel is oscillated back-and-forth during advancement thereof in a predetermined rotated direction.

Abstract: A plate of polygonal shape having indicia printed on at least one side thereof is trapped between transparent hemispherical domes each having a spindle extending therefrom.

Abstract: Flexible headband is connected to one side of a flashlight in a manner such that the headband may be wrapped around the body of the flashlight with the terminal wrap being secured to the flashlight when the headband is not in use.

Abstract: An electronic toy game of skill for two players includes an array of illuminatable display elements, such as LED's, randomly selected ones of which are illuminated during each round of play; a corresponding plurality of player switches which are located adjacent to the associated display elements and control means for associating those switches with the lamps in the given manner. During each round of play a continuously perceptible time period is established by the control means. This time period has a duration related to the number of LED's that are to be illuminated during a given round of play. During each player's turn, some LED's are illuminated and by operating the player switches, the player attempts to extinguish the LED's prior to expiration of the time period. Failure to successfully extinguish such LED's results in termination of that player's turn. The winner of the game is that player who first successfully completes a predetermined number of rounds.

Abstract: A carrying case may be opened to present upper and lower scene-simulating objects including a serpentine roadway for toy vehicles which may coast down the roadway from the top of the rearwall of an upper carrying case portion to the bottom wall of a lower carrying case portion hinged to the upper carrying case portion along a diagonal line.

Abstract: The piston portion of a coupling for a mechanical phonograph is split lengthwise and joined together at a closed end by a living hinge so that the compression spring which biases the piston against the tonearm will exert a spreading force to the piston conforming it to the inside diameter of the cylinder or collar on the speaker cone, thereby achieving the close clearance required to transmit recorded sound vibrations to the speaker cone.

Abstract: A remote controlled sports game having first and second figures operable on a playing surface with each of the figures having receivers tuned to different frequencies for operation by radio transmitters with the control of movement of the figures against a game object such as a ball being effected remotely. A drive system is provided for driving two wheels simultaneously with reversal of direction of the motor operating a cam slide member through a spring clutch to lift one drive wheel for providing a tight turning radius.

Abstract: A hydro-jet-type nozzle reciprocably mounted in an elongated slot adjacent which a user of the device may position a body portion to be massaged by the hydro jet.

Abstract: Elongated support members are coupled to the elongated grip portion of a hand-held implement, such as a reading glass, mirror or the like, in a manner such that each support member may be moved from a convergent position where the major axes of the support members lie substantially parallel to each other and to the major axis of the grip portion in contact therewith along a major portion of the length of each support member to a divergent position where each of the support members extends laterally from the lower end of the grip portion with the major axes of the support members diverging outwardly from each other for supporting the implement in a vertical or a near-vertical position, thereby freeing the hands of a user of the implement. The support members and hand-held implements may be held in many predetermined rotated positions with respect to their associated grip portions.

Abstract: A tubular member holds a paper, tubular fuselage above a paper wing supported by a plate and below a folding die from which a fuselage presser depends; whereby the fuselage may be attached to the wing and the edges of the wing may be folded into an aerodynamic configuration when the die and tubular member are brought into working association with a pair of upstanding plates which are spaced apart in a manner such that the fuselage and its associated parts may be positioned between said plates while said die folds the wing edges over the upper edges of the plates.

Abstract: A steering mechanism (10) for a scale-model vehicle (12) includes a pair of journal boxes (50), (51) having arcuate racks (56), (57) provided on their lower and upper cover plates (54), (53), respectively, for coacting with pinions (62) to swing wheel-carrying axles (60) through predetermined turning arcs when vehicle (12) is moved in reverse. Stops (110) and (112) are engaged by axles (60) to limit the turning arc in reverse and to hold the wheels (44), (46) on a straight course when vehicle (12) moves forwardly.

Abstract: A generally rectangular sheet of self-supporting material such as paperboard is scored and cut in such a manner as to be foldable into a fast food carry-out tray which can be converted after use by manipulation of preformed tear and fold lines into a hand puppet. The fast food carry-out tray has at least one opening extending into a tray cavity for receiving a paper cup or food item. In a preferred embodiment, the tray is also provided with a box-like cover. The sheet material is printed with designs or indicia which suggest a hand puppet character. Cut-out tabs may also be provided for insertion into the sheet material to further create an impression of eyes, a nose, or the like of a hand puppet character.

Abstract: A colored disc is positioned in a bezel beneath a clear, plastic simulated gem for imparting color to the gem; the bezel may be affixed to a band for use as a finger ring and a plurality of discs of different colors may be furnished with the ring so a child user may make her own simulated birthstone.

Abstract: A hand-held electronic game of skill. First and second columns of LED's display the positions and movements of the piece indicia of respective first and second players between respective starting and finishing positions. During the first state of a stop/go indicator, the manipulation of either of two player input switches causes the piece indicium displayed on the respective column to advance toward its finishing position. During the second state of the stop/go indicator, the manipulation of either of the two player input switches causes the piece indicium displayed on the respective column to be returned to its starting position. The first and second states of the stop/go indicator are established alternately, and continue for periods the durations of which vary randomly between predetermined minimum and maximum values.
