Abstract: An apparatus for tuning the weight distribution in a vehicle, typically a high performance automobile, is provided. The apparatus includes a weight tray having an internal passage, a screw element, typically a threaded bolt, that extends into an end of the internal passage, a retainer at the same end of the passage, defining a hole through which the screw is rotatably retained, a primary weight is disposed within the passage and having a bore into which the screw extends and a nut or a threaded portion (i.e., a tapped portion) disposed within the bore that operatively engages the threads of the screw. Additional weights may be attached to the primary weight to increase the weight in the weight tray. The primary and additional weights may further include interlocking portions that are suitably configured to interlock with a corresponding interlocking portion on another weight. One or more of the weights may be assembled from two weight segments to facilitate assembly of the apparatus with minimal tools.

Abstract: An inductor for inductively heating bearing surfaces of a crankshaft is machined from a block of copper to provide parallel, closely spaced and integrally joined inductor block portions having machined coolant passages therein. The machined inductor is rigidly supported between juxtaposed side plates having portions of the inner surfaces thereof machined to provide recesses which receive the inductor and in which the inductor is clampingly engaged between the plates. Positioning fingers are supported by the side plates to accurately position the active face of the inductor relative to a bearing surface to be heated, and tubular leads extend upwardly between the side plates for connecting the inductor across a source of power. An inlet conduit for coolant extends laterally between the side plates, and the tubular leads provide outlets for coolant flow from the inductor.

Abstract: Compacted, unsintered powdered metallurgical workpieces are sequentially shuttled to a series of induction heating units in controlled environments to expel volatile and progressively raise the temperature of the workpiece to an effective sintering temperature.
