Patent number: 4088080Abstract: A six-wheel railway motor truck for swivelly supporting a locomotive body is connected to the same for the effective transmission thereto of draft and braking forces at a level at or near that of the rail whereby the vertical moment arm through which traction forces might act to tip the truck frame and thereby cause load transference from axle to axle is minimized, with corresponding minimization of such load transference. The truck comprises a rigid frame resiliently supported on the three axles, a body support bolster supported on the sides of the truck frame by upright springs and held against swivelling movements or longitudinal movements with respect to the truck frame while being free for limited vertical and transverse movements with respect to the truck frame.Type: GrantFiled: July 26, 1976Date of Patent: May 9, 1978Assignee: General Steel Industries, Inc.Inventor: Keith L.

Patent number: 4056087Abstract: An internal combustion engine carburetor is provided with means for introducing two separate types of liquid into the engine, one of the liquids being gasoline and the other a non-gasoline liquid, such as methyl alcohol, tertiary butyl alcohol, or other alcohols. The carburetor maintains the two liquids separate prior to their introduction into the Venturi to avoid problems normally incurred in blending other liquids with gasoline in liquid form and is constructed to prevent introduction of the non-gasoline liquid during normal idling and starting conditions and to introduce it in metered quantities during normal operation. To ensure vaporization of the two liquids in the primary Venturi, hot air at a temperature at least as high as the end point of the gasoline is introduced directly into the primary Venturi.Type: GrantFiled: March 26, 1976Date of Patent: November 1, 1977Assignee: F.
