Abstract: A motorcycle stand designed for hands-free operation that enables the rider to safely park a motorcycle in a secured, upright position without the aid of another individual and without having to dismount from the motorcycle. The motorcycle stand includes: rigid base; adjustably attached ramp; ramp-locking device; wheel stop; pairs of adjustably attached and opposing wheel supports; and a multitude of anti-skid pads. The wheel supports guide the wheel into the parking position and engage the sides of the front wheel. The weight of the motorcycle ensures the front wheel is engaged in the motorcycle stand such that the motorcycle cannot be moved forward, backward, or tipped from side-to-side. The steep inclination of the ramp and a locking device prevent the parked motorcycle from accidentally rolling backward and out of engagement with the motorcycle stand, even when the motorcycle is parked on an inclined surface.

Abstract: An oil change device to facilitate the collection of the spent motor oil from an internal combustion engine's ferromagnetic crankcase and ferromagnetic oil filter, having a flexible tube connecting a sealing cover unit to an oil collection container. Permanent magnets, imbedded in the sealing cover unit provide a means to attach the sealing cover unit to the crankcase and oil filter. The distal end of a wrench shaft protrudes through an orifice in the base member and extends to the superior surface of the baffle member. A wrench socket that fits the crankcase drain plug head is connected to the distal end of the wrench shaft and a socket wrench, attached to the proximal end of the wrench shaft, is used to unscrew and remove the crankcase drain plug. An oil filter piercing tool is connected to the distal end of the wrench shaft and used to pierce the skin of the oil filter when a striking blow is delivered to the proximal end of the wrench shaft.

Abstract: An electronic monitoring system to accurately measure a vacuum in an interstice between inner and outer walls of a dual-wall container or pipe which allows highly accurate analysis of vacuum differential to discover and confirm a leak in either the inner or outer walls of the container or pipe within minutes.
