Title: Innovations by Andrew P. Klein in Fire Fighting Technology

Introduction

Andrew P. Klein is an accomplished inventor based in Appleton, WI (US). He has made significant contributions to the field of fire fighting technology, holding 2 patents that enhance the efficiency and effectiveness of rescue and fire fighting vehicles. His innovative designs focus on improving the delivery and proportioning of foam additives in emergency situations.

Latest Patents

Klein's latest patents include a "Foam Additive Supply System for Rescue and Fire Fighting Vehicles." This system is designed to supply a pre-determined ratio of liquid foam concentrate and water to a mixing device located immediately upstream from a fire fighting nozzle. The system is electronically balanced by measuring pressure from multiple pressure signal sensors and transmitting these signals to a controller unit. Additionally, a foam additive pump is powered by a fixed displacement piston motor, which is electronically modulated independently of the water pump's operation level. This control system responds to both the water pressure developed by the water pump and the foam liquid concentrate pressure from the additive pump.

Another notable patent is the "Foam Concentrate Proportioning System and Methods for Rescue and Fire Fighting Vehicles." This system and method maintain a desired additive-to-water ratio in a fire-fighting system. It includes a water flow sensor to measure the water flow rate, a water pump, a hydraulic pump, and a linear hydraulic cylinder driven by the hydraulic pump. An additive pump is mechanically coupled to the linear hydraulic cylinder, and a pump displacement sensor senses the position of the additive pump. This sensor communicates with the water flow sensor to maintain the pre-determined ratio of additive to water.
