Abstract: A solid state voltage regulator for regulating the output voltage in the electrical system of a motor vehicle by controlling the current flow in a field winding associated with a DC generator. Current flow in the winding is permitted only when load current is being supplied by the regulator. The regulator is packaged in a housing which can be mounted directly to the field winding and ground terminals of the generator. The regulator is sepcifically designed for regulating the voltage associated with a motor cycle electrical system.

Abstract: Motorcycle apparatus is disclosed, in its preferred form, as a device for filtering and cooling oil including a novel and unique concealed mounting. The oil filtering and cooling device includes a casing having internal and external heat dissipating members for receiving and transferring heat from the oil, through the casing, to the outside ambient air or atmosphere. The internal heat dissipating members are shown in the preferred embodiment as including fins and shoulders which define an oil filter capturing cavity. An oil filter is biased inside the cavity by a spring which allows the oil to bypass the filter when the filter becomes clogged. The concealed mounting of the apparatus is accomplished by utilizing a mounting plate securable within an indentation formed in the back of the apparatus. Specifically, the mounting plate holds bolts outstanding from the apparatus through apertures in the mounting plate by capturing the heads of the bolts in apertures formed within the indentation of the apparatus.
