Publication number: 20220388428Abstract: Electrified roadway systems include a roadway, and vehicles configured to operate on the roadway. The roadway has a base, and two electrically-conductive rails mounted on the base. One of the rails is electrically connected to a source of electric power, and the other rail is electrically connected to an electrical ground. The vehicles include non-electrically-conductive tires, and an electric motor mechanically connected to, and configured to rotate at least one of the tires to propel the vehicle along the roadway. The vehicles draw electric power from the roadway via two electrical pickups that contact the respective rails, and a retracted position at which the pickups are out of contact with the rails. A wear-resistant cover can be positioned on each of the rails. The wear resist covers can have features that maximize the contact area and the contact force between the covers and the rails.Type: ApplicationFiled: January 20, 2022Publication date: December 8, 2022Inventor: William E.M.

Patent number: 9353879Abstract: A float actuated valve assembly for battery electrolyte replenishment is disclosed. A housing engages an opening in a battery cell. An inlet in the housing is connectable to a water source. A valve in the housing controls the water flow to the cell. The valve is connected by a link to a four bar mechanism that is attached to a float. The float is buoyantly supported and rises and falls in response to the electrolyte level within the cell opening and closing the valve to admit or halt the flow of water to the cell. A baffle prevents fouling of the mechanism by splashing electrolyte. A flash arrester is positioned between the valve and the inlet to quench hydrogen-oxygen explosions between cells. The float is adjustable for different sized cells. A side viewable electrolyte level indicator is provided in the housing. Flash arresters for venting gas are also mounted.Type: GrantFiled: January 19, 2005Date of Patent: May 31, 2016Assignee: PHILADELPHIA SCIENTIFIC LLCInventors: William E. M. Jones, Trevor Alden

Patent number: 7392820Abstract: An automatic shut-off valve suitable for watering of batteries is disclosed. The valve is formed by a chamber having an inlet and an outlet. A seat surrounds the outlet. A spring biased piston within the cylinder is movable into and out of sealing engagement with the seat to open and close the valve. A flow deflecting surface is positioned between the inlet and the piston. Water flow is directed around the piston to eliminate drag that would force the piston into engagement with the seat. A second deflector surface directs flow against the piston to bias it open. An actuator cup, fed by a nozzle extending from the outlet, draws the piston into engagement with the seat when the cup is sealed by engagement with the electrolyte surface. The valve may also employ a float actuator connected to the piston.Type: GrantFiled: January 19, 2005Date of Patent: July 1, 2008Inventors: William E. M. Jones, Trevor Alden

Patent number: 7326489Abstract: A catalyst device for use with battery cells to recombine oxygen and hydrogen gas and thereby improve the performance and life of such cells. The catalyst device has the ability to filter out catalyst poisons and control the temperature of the recombination reactions. A container houses the catalyst within a chamber. A catalyst poison filter is provided in the chamber with the catalyst. The movement of gas and vapor to and from the chamber is controlled by a microporous section of the device. The pore size is chosen to allow gas and vapor to pass, but not liquids, and to also prevent a flame from passing through. Within these parameters the pore size can also be chosen to control and or limit the amount of gas that can pass through to the catalyst in a given time period. Preferably, the microporous section is formed as a disc that seals an opening in the chamber.Type: GrantFiled: January 6, 2003Date of Patent: February 5, 2008Assignee: Philadelphia ScientificInventors: William E.

Publication number: 20040131926Abstract: A liquid electrolyte battery is disclosed having autonomous watering and electrolyte mixing systems. Watering is effected through a fluid conduit and a valve system mounted on the battery providing fluid communication and flow control between a fluid source and the battery cells. Mixing of the electrolyte is effected by pumping air into the battery cells to prevent acid stratification during charging using an air conduit and air pump mounted on the battery. The fluid conduit provides fluid communication between the air pump and the cells. A controller mounted on the battery receives input signals from various sensors indicative of electrolyte level and charging status and controls the valve system and the air pump to effect watering and electrolyte mixing. A protective cover is mounted on the battery to restrict access to the controller and the air pump.Type: ApplicationFiled: October 27, 2003Publication date: July 8, 2004Inventor: William E. M. Jones

Patent number: 6274263Abstract: A lead acid storage battery cell having a sealed housing in which a positive electrode and a negative electrode are immersed in a liquid electrolyte. The negative electrode is partially exposed to a gas space within the battery cell housing. A pressure relief valve allows excess gas to escape the battery cell while preventing air from outside the cell from entering the gas space. Exposing a section of the negative plate to oxygen gas that evolves within the battery and collects in the gas space reduces water consumption of the cell and extends the maintenance-free life of the battery. The addition of a catalyst to recombine oxygen and hydrogen offers further improvement.Type: GrantFiled: November 6, 1998Date of Patent: August 14, 2001Inventor: William E. M. Jones
