Abstract: A wheeled caster assembly engages a carrying case at the handle thereof, but the assembly is easily removed from the case. The caster assembly has a base on which the case rests. The base is supported by a wheeled caster at one end and a strut at the other end. A keel on the underside of the base is disposed between the caster and the strut. The keel contacts the crossbar of the handle such that the upper side of the base faces against the case. A corner of the case fits with a complementary corner formed by the base and an upright flange at the one end of the base.

Abstract: A starter circuit provides capacitor-assisted energization of a vehicle's starter motor and prevents damage to capacitors in the circuit. The circuit includes a battery, a capacitor pack and a power control switch in the line connecting the pack to the motor and battery. The starter circuit includes a regulator for limiting current flow from the battery to the pack to a selected rate, the regulator being connected between the battery and the pack in parallel with the power control switch. A regulator switch is between the regulator and the capacitor pack. The starter circuit has a control circuit for selectively opening and closing the switches in response to a voltage level of the pack. The control circuit detects the voltage level of the pack, opens the power control switch when the voltage level falls below a predetermined threshold and simultaneously closes the regulator switch.

Abstract: A demonstrator for mounting, operating and displaying a multiplicity of automotive vehicle components comprises an open-frame exoskeleton of aluminum tubes. The tubes are in a configuration suggestive of the shape of an automotive vehicle. The demonstrator is light in weight, is easily shipped and is movable by a single person. A central compartment of the exoskeleton resembles a passenger compartment and has doorways similar in height and width to door openings of the vehicle. A front compartment of the demonstrator resembles a vehicle engine compartment, this compartment defining a generally horizontal window free of other structure of the demonstrator. The front compartment includes front wheel-well outlines defined by tube segments welded together. A rear compartment of the demonstrator similarly defines rear wheel-well outlines.
