Abstract: A remote controlled, all-terrain toy vehicle has treads on both its left and right sides. Each tread extends over front and rear oversized, resilient wheels that allow the vehicle to travel on its top and bottom sides in forward and reverse. The vehicle is adapted for high performance on hard, flat surfaces, such as pavement, as a result of an elevated ridge on the tread that ensures low surface area contact with the ground and, which in turn, reduces ground resistance and increases the operating speed of the vehicle.

Abstract: A toy doll, posable and simulating stances or positions and movements of a skater, dancer or the like. The device includes a torso with arms and leg which may be frictionally pivotably connected to the torso to enable posing the doll in a wide variety of positions. The doll is supported atop a self-propelled base by engagement of a foot or skate, such as an ice skate, roller skate, roller blade or the like, with a platform which forms a portion of the upper surface of the base. The base is supported by a front wheel and by two spaced apart rear wheels. The base is propelled by one rear wheel and steered by a replaceable profile cam-guided front wheel. The platform is rotated along with the doll about an upright axis as the base is propelled over a horizontal surface through a repeated geometric pattern defined by the particular profile cam selected.

Abstract: The manufacture of a substantially fully methylated, substantially fully methylolated melamine composition is carried out by a continuous process in which the methylolation of melamine is conducted in two stages, the first stage being effected at an acidic pH and the second stage being effected at an alkaline pH. The reaction mixture is then concentrated and reacted with methanol after which all of the unreacted volatiles and precipitated salts are removed to provide the product composition.
