  • Patent number: 4880655
    Abstract: A chocolate syrup sweetened by honey which allows the syrup to be kept at room temperature even after opening. An approximate ratio of 8 parts honey to 1 part cocoa by weight is maintained in the formulations. When these are mixed together, water is also added which will vary from between 4 to 25% by weight of the total mixture. A flavoring, in less than 2% by weight of the syrup, can also be mixed into the syrup.

  • Patent number: 4232755
    Abstract: Relates to a lightweight electric battery powered motor vehicle which is divisible into separable front, middle and rear sections. The front section includes a pair of steerable road engaging wheels, the middle section includes a seating compartment for two or three persons, and the rear section includes a single road engaging drive wheel driven by an electric motor and support for batteries and controls therefor. The basic supporting structure of the vehicle is served by a double set of longitudinally extending main frame members each preferably of tubular cross-section and extending through the middle section and into the front and rear sections of the vehicle. The front and rear sections of the vehicle include sleeve-like appurtenances which telescopingly fit over the terminal ends of the tubular frame members thereby enabling the front and rear sections to be easily slid off for repairs or replacement.

  • Patent number: 4171730
    Abstract: Relates to a lightweight electric battery powered motor vehicle which is divisible into separable front, middle and rear sections. The front section includes a pair of steerable road engaging wheels, the middle section includes a seating compartment for two or three persons, and the rear section includes a single road engaging drive wheel driven by an electric motor. The basic supporting structure of the vehicle is served by a double set of longitudinally extending main frame members each preferably of tubular cross-section and extending through the middle section and into the front and rear sections of the vehicle. The hollow interiors of the tubular frame members are substantially filled with resiliently compressible and deformable balls which are compressibly engagable with one another when external forces are applied against either bumper in the direction of the vehicle and transferred to the balls by the push rods associated with each bumper.
