A novel laminar flow nozzle for fuel injected racing cars is described herein. One novel feature comprises a narrow angle between converging conduit component channels. These channels, in turn, supply vaporized fuel and nitrous oxide to the main chamber of the nozzle. Another important novel feature is the integral structure of the nozzle; the conduit components, generally rigid and cylindrical in shape, are physical integral components of the nozzle. The result of our invention is a nozzle with a smooth laminar flow of gases which results in less turbulence and greater horsepower.

A toothed belt construction formed mainly of thermoplastic material and method of making the same are provided, the method including the steps of disposing at least one layer of the thermoplastic material about the outer peripheral surface of a building drum that has the outer peripheral surface thereof defined by alternating teeth and grooves, and then forcing the one layer of thermoplastic material toward the drum while the temperature of the one layer of thermoplastic material is above its softening temperature and below its melting temperature so as to cause at least part of the one layer of thermoplastic material to exude into the grooves to form at least part of the plurality of teeth of the belt construction.

Toothed belt formed mainly of thermoplastic material

A method of making tooth belts by formation thereof about the outer peripheral surface of a building drum having a generally cylindrical configuration and a surface defining a series of parallel, tooth-shaped grooves. The belts are formed by wrapping a fabric circumferentially around the building drum and winding a cord of tensile material helically about the fabric. A layer of thermoplastic material is formed about the cord of tensile material, and a cord of shrink material is wrapped helically about the layer of thermoplastic material. The shrink material has a higher softening temperature than the thermoplastic material and will shrink at a temperature below its softening temperature. Pressurized steam is applied to the shrink material at a temperature below its softening temperature and between the softening temperature and the melting temperature of the thermoplastic material. This shrinks the shrink material and extrudes a thermoplastic material through the tensile material, against the fabric and into the tooth-shaped groves of the building cylinder.
