With a total of 3 patents to his name, Zander's work reflects a commitment to enhancing safety and efficiency in liquid dispensing systems.

Latest Patents

One of Zander's latest inventions is the Ball Valve Coupling. This environmental coupling is designed to reduce spillage to less than 1 mL. The coupling features a first convex ball valve and a second concave ball valve. One of the ball valves includes flat surfaces and a retainer with corresponding 'flats' that keep the valve on centerline, allowing for actuation without damage. The design incorporates several safeguards against spillage, including handles with concave and convex edges to prevent incorrect sequencing, interlocking means to maintain connection when the first valve is open, and a handle button release with a secondary lock.

Another significant invention is the Restrictor Valve for a Metered Liquid Dispensing System. This restrictor valve acts as an outlet valve and utilizes a spring-biased, shiftable anti-siphon check valve to prevent backflow from the receiving tank. It is connected to the delivery end of the discharge hose and is controlled by a central electronic unit. The restrictor valve includes a sensing unit that signals the electronic control when liquid is present at the outlet. Additionally, it features a low spill coupling to minimize environmental impact and may include a vacuum breaker valve for air admission during reverse pump operation.
