Abstract: A highway game has a base supporting a conveyor-like roadway belt on which a toy vehicle is mounted. The vehicle has a control mechanism mounted at one end of the base and this mechanism includes a winding device wound with a tether secured to the vehicle. The roadway belt is driven in one direction by a motor to turn the wheels of the tethered vehicle and simulate movement of the vehicle in the opposite direction. The winding device of a simplified form of the game is mounted on a transverse shaft which can be rotated manually to shift the vehicle longitudinally on the rotating roadway belt. In a preferred embodiment of the game, the control mechanism is driven by a power take-off from the motor and the winding device is slidably mounted on a control shaft which is movable to engage and disengage the device from the drive so as to achieve a similar longitudinal movement of the vehicle.

Abstract: An orthodontic appliance is provided which applies a pulsating force to the tooth to be moved, rather than a continuous force as in the case with the prior art devices. The invention is predicated on the concept that when pulsating forces are applied to the tooth, there is little or no hyalinization and consequently more cellular activity, giving rise to more oesteoclastic activity for bone resorption and more oesteoblastic activity for bone opposition. Moreover, the pulsational effect of the tooth on the adjacent periodontal membrane and bone tends to loosen their fibrous structure, and helps the tooth to find a path of least resistance through the bone.

Abstract: A toy apparatus with a photoemissive motor control system includes a chamber into which a phosphorescent member is placed, whereupon photoemission acts upon a photosensitive element to activate a motor control circuit for operation of a motor which drives the toy apparatus. An activation apparatus is provided, which includes a battery operated lamp for periodic re-energization of the phosphorescent member.

Abstract: A flying toy of the boomerang type having two airfoil arms extending horizontally from a center portion. Each arm carries at its outer end a horizontally disposed, annular-shaped stabilizer having a horizontally disposed outer periphery whose diameter is approximately twice the horizontal width of the arm at the juncture of the arm and the stabilizer, and having an inner periphery which is disposed in the same horizontal plane as the outer periphery, and which defines a center opening through the stabilizer. The stabilizer has a convex top annular surface and a concave bottom annular surface extending between the inner and outer peripheries. During flight, the stabilizers serve simultaneously as airfoils, airfoil arm stabilizers, and a gyroscope for the flying toy.

Abstract: Toy mother and baby animal figures which simulate the giving of birth to the baby animal. The mother animal figure includes a hollow body having an interior chamber with an exit opening. An openable door is provided over the exit opening. The toy baby figure which is representative of an offspring of the mother animal is disposed within the chamber. The baby figure is capable of being collapsed, as by having multisection foldable legs which fold up against its body, so it will fit within the chamber. A conveyor mechanism is included within the mother animal figure and is manually actuable by the user to move the baby figure toward the exit opening while also opening the door so that the baby figure may be pushed out through the exit opening and thus be "born". After it is born, the baby figure may be expanded as by having its legs unfolded and it may be self-standing. The chamber may also be openable to permit replacing the baby figure.

Abstract: A surgical bone operation instrument that has a straight tube-shaped shaft and arrangement coaxially in relationship to the longitudinal axis of the instrument to form a continuous channel from one end of the instrument to the other including the end parts, which serves for the guidance of materials utilized in the operation of the instrument, and a driving assembly being of a bell-type electrical motor with the stator enclosed within the bell-shaped rotor, the latter having windings of lacquered wire embedded in a plastic material, the windings further being wound to form a hollow cylinder of relatively thin wall thickness to form a part of the bell-shaped rotor, the mechanical structure of the rotor being furthermore reinforced by glass fibers.

Abstract: A modular toy is provided in the configuration of a building, such as a doll house, formed of a plurality of modular units, each representing, for example, a room or a group of rooms.

An operator is secured to the lips behind the face and is reciprocated to move the lips inwardly and outwardly in a suckling type action. The nipple of a nursing bottle or the thumb of the doll's hand is manually insertable into the doll's mouth to provide realism when the lips are activated as described.

Abstract: An inflatable toy which when inflated has the contour of a hassock. The toy features a cylindrical envelope and inner radially-extending planar baffles, these elements being composed of soft limp flexible material such as a thermoplastic plastic. When the toy is inflated by introducing air under mild pressure into the envelope, the top and bottom walls of the envelope are distended so as to assume the contour of the top and bottom of a hassock, i.e. with a central bulge and discrete radial outward bulges. This configuration is formed by disposing the baffles vertically and mutually angularly spaced, each of the baffles extending radially from near the central axis of the envelope and terminating short of the periphery of the envelope, with rectilinear attachments of the top and bottom edges of each of the baffles to the top and bottom walls of the envelope. The baffles are tautened by outward force exerted on the top and bottom walls between the baffles, by the pressure of the inflating air.
