Title: Andries J Stoltz: Innovator in Fluid Dynamics and Monitoring Systems
Introduction
Andries J Stoltz is a notable inventor based in Pretoria, South Africa. He has made significant contributions to the fields of fluid dynamics and monitoring systems, holding a total of 2 patents. His innovative designs have practical applications, particularly in swimming pool cleaning technology and acceleration monitoring.
Latest Patents
Stoltz's latest patents include a valve assembly and an acceleration monitoring system. The valve assembly features a hollow body that houses a tubular flexible diaphragm, allowing for controlled fluid flow. This design enables the diaphragm to automatically contract and expand, creating a pulsating flow of fluid, which is particularly useful in swimming pool cleaners that operate on reduced pressure from conventional filtration systems.
The acceleration monitoring system consists of a sensor that responds to acceleration in a predetermined plane. It includes a float structure immersed in liquid, which pivots when subjected to acceleration. This system can indicate varying degrees of acceleration based on the movement of the float structure, with the potential for dual sensors to monitor acceleration in two directions.
