Abstract: A fuel supply system for a vehicle uses a seal-less piston LPG injunction pump which pumps fluid from a storage tank to an engine. The pump uses the vehicle's pneumatic air system, wherein the pressurized air of this system alternatingly drives an actuator magnetically coupled to a piston.

Abstract: A fuel supply system for a vehicle uses a multi-piston LPG injunction pump which pumps fluid from a storage tank to an engine. The multi-piston pump uses the vehicle's pneumatic air system, wherein the pressurized air of this system alternatingly drives at least two pistons of the piston pump. Each piston moves through a pumping stroke and a return stroke wherein one piston moves through a pumping stroke, while the opposite piston moves through a return stroke. The pump includes barrier fluid chambers surrounding each of the pistons wherein during a pumping stroke of one piston, a first barrier fluid chamber associated with the one piston decreases in volume as the piston displaces through its pumping stroke. This reduction in volume of the barrier chamber drives the barrier fluid out of the first barrier fluid chamber into a second barrier fluid chamber associated with the second piston.

Abstract: A track and field shoe has spikes extending outwardly from a forward portion of an outsole of the shoe. A shoe cover provides a bottom plate resting in contact with the forward portion of the outsole of the shoe and has a similar peripheral shape. The shoe cover further includes an elastic clamping fabric engaged on three mutual edges peripherally with the bottom plate. A fourth mutual peripheral edge of the clamping fabric and the bottom plate forms an opening into the shoe cover for accepting a tip of the shoe inserted into it upon stretching the clamping fabric. A hem in the clamping fabric extends parallel and adjacent to the fourth peripheral edge and terminates with a hem seam. The hem seam has a maximum elastic yield below that of the clamping fabric. This is critical as it allows the clamping fabric to stretch to fit a wide range of shoes, while enabling the hem seam to fit more tightly around the tip of the shoe applying a clamping force.

Abstract: As rotational mechanical devices accelerate or decelerate, they have an opposite reaction against their housing and/or their surroundings in fact to move the earth. This reaction represents wasted energy that is lost to the system. The invention comprises the use of equal and opposite force from an energy source gravity via activated spring, cable, or counterweight applied fresh as acceleration begins or lift and release from opposite or adjacent sides to reset. These methods can conserve as much as three-fourths of the applied energy for motors, machines, and other motion-related applications.

Abstract: As rotational mechanical devices accelerate or decelerate, they generate torque against their housing and/or their surroundings. This torque represents wasted energy that is lost to the system. The invention comprises the use of equal and opposite force from an energy source such as a spring or counterweight to counteract to the torque generating forces in the mechanical device.

Abstract: Devices herein described utilize vehicles that are propelled, braked, and steered by means of a process called Inertial Propulsion Plus. This consists of a "power phase" to extend the weight(s) from the vehicle, alternated with a "null phase" to cancel out the return phase or stroke reactions. This process is made workable by selectively applying a pure external force derived from the pathway and opposing the movement of the weight(s) on the power phase. For non-travel-related applications, the inherent displacement can be harnessed by a treadmill or other ways for a power source to increase available power and reduce pollution.
