Abstract: One embodiment is a combined welder and fume extractor system having a chassis assembly along with a controller and a user interface which are substantially within the chassis assembly to control operation of the system and allow a user to interact with the system. A filter compartment within the chassis assembly has at least one filter to extract welding fume particles from a stream of air forced through the filter compartment. An extractor compartment within the chassis assembly has at least one fan to force the stream of air through the filter compartment. A welding power source compartment within the chassis assembly has welding power electronics circuitry to generate welding output power for a welding operation. A wire feeder compartment within the chassis assembly has a spool of a welding wire electrode and a wire feeder to feed the welding wire electrode from the spool.

Abstract: An in-line vacuum breaker for a flexible hand held shower. The vacuum breaker includes a frusto-conical body with a water flow passage extending therethrough. The frusto-conical body has an inlet cavity at one end and an outlet cavity at the opposite end. An outlet plug is threaded into the outlet cavity. A first passage formed in the outlet plug leads to an outlet opening. A second passage in the outlet plug extends parallel to the first passage and leads to a vent opening. A manifold passage defined in the outlet cavity by the body and the outlet plug connects the body passage and the first and second passages. A first check valve in the first passage permits fluid flow only from the manifold passage to the outlet opening. A second check valve positioned in the second passage prevents fluid flow from the manifold passage to the vent opening. A third check valve positioned in the body passage permits fluid flow only from the body inlet opening to the manifold passage.

Abstract: A system for the delivery and control of an air/oil mixture used to lubricate large bearings in heavy duty applications such as steel mills is provided. The system includes a mixing module for mixing air and oil and delivering the air/oil mixture through a plurality of connecting lines to a plurality of bearing housings. Each of the connecting lines or the outlet leading to the connecting line is, in turn, connected to its own individual solenoid. Each solenoid is connected to a common pressure transducer which is connected to a controller. The controller sequentially opens the solenoids one at a time thereby establishing communication between one of the connecting lines and the common transducer at a time. The transducer receives pressure signals fr6m each connecting line converts the pressure signals to analog signals before transmitting the analog signals to the controller.
