Abstract: A multi-cartridge cutting tool includes a body with a plurality of cartridge-receiving pockets, and a plurality of insert-receiving cartridges mounted to a respective pocket. A round cutting insert is mounted to each cartridge. The pockets are formed at predetermined distances from a central, longitudinal axis of the body to form a first group and a second group of cutting inserts such that the cutting edges of the first group of cutting inserts and the cutting edges of the second group of cutting inserts are located at different axial and radial distances from the central, longitudinal axis of the body to perform different machining operations. The cutting tool may be used as part of a railway wheel boring assembly.

A third group of cutting insert(s) may exist for cutting tools with an odd number of cutting inserts. The different types of machining pockets allow for high feed rates, while greatly improving the life of the cutting insert as compared to conventional cutting tools. A railway wheel boring assembly is also disclosed.

Abstract: A fuel line disconnection tool includes a handle member with a hand grip end and a slotted opposite head end adapted to receive generally mirror image flanged adapters having semi-cylindrical tubular projections which enable placement of the adapters in the slot at the head end of the handle. The adapters may then be fitted about a fuel line and the handle attached thereto and manipulated to disengage the connection mechanism between the fuel line and fuel filter.

Abstract: A medical ventilator system is disclosed which automatically controls and modifies the oxygen support provided to the patient. The system includes a source of pressurized oxygen and a fluid conduit extending between the pressurized oxygen source and a patient. A valve is fluidly connected in series with the conduit which is variably controllable to vary the oxygen support for the patient. A pulse oximeter provides an SpO2 signal representative of the blood saturation of the patient. A controller is responsive to the magnitude of the SpO2 signal as well as the rate of change of the SpO2 signal for varying the oxygen support (FiO2) to the patient by variably actuating the valve. Preferably, the controller utilizes fuzzy logic to determine the proper oxygen support for the patient.

Abstract: A tool for brake spring maintenance provides the ability both to release brake springs and then hold them out of the way for removal and replacement of brake shoes or for other maintenance operations related to drum brake arrangements. A main support bar is adapted to be received on an exposed wheel mounting member. The bar has a pair of threaded pins and cooperating threaded nuts for controlled axial movement of the pins. The pins have hooked ends and are situated for engaging respective brake springs whenever the tool is properly positioned on the exposed wheel mounting member. By rotating the threaded nuts to move the pins a set axial distance with the pin hooked ends engaged with the brake springs, such springs can be drawn back from their hold on the brake shoes, to permit disassembly and maintenance of the entire drum brake arrangement.
