Title: Fuel injection system for combustion-powered tool
Inventor: ROBINSON JAMES W
IPC: B25C5/00
Filed: 1996-09-20
Granted: 2000-04-11
Abstract: A fuel system is provided for a combustion-powered tool having a self-contained internal combustion power source with a combustion chamber, and constructed and arranged for driving a drive blade to impact a fastener and drive it into a workpiece. The tool includes a housing having a main chamber enclosing the power source and having a first end adjacent a nosepiece wherein the fasteners are positioned prior to driving, and a second end opposite the first end and adjacent the combustion chamber. A fuel cell chamber is in communication with the main chamber and has a first chamber end corresponding to the first end of the main chamber and a second chamber end corresponding to the second end of the main chamber. A fuel metering valve is disposed in the fuel cell chamber at the first end so that a fuel cell having a fuel outlet end operationally inserted into the fuel cell chamber will engage the valve so that fuel is dispensed into the valve in a location closer to the first chamber end than to the second chamber end.

Title: Method and apparatus for aggregate treatment
Inventor: QUINN DENNIS E
IPC: F23D14/64
Filed: 1996-01-11
Granted: 2001-07-03
Abstract: A treatment system and method is disclosed for heat treating aggregate, for example, an aggregate dryer (10) of the type which uses a burner (12) and rotating drum (14) for veiling aggregate into a thermal flow path. The invention provides a plurality of mixers (42) which safely mix fuel and oxidant into a premix which is delivered to a reaction chamber (56). The premix is combusted and recirculated within the reaction chamber (56) to insure uniform and complete combustion, resulting in lower emissions of pollutants such as carbon monoxide, volatile organic compounds, and nitrogen oxides and also lower combustion roar. This uniform and complete combustion results in a more uniform thermal profile within the rotating drum (14), resulting a greater throughput of processed aggregate and a more efficient consumption of energy. The invention also includes a "tunability" feature for varying the delivery of fuel to the burner in order to avoid resonant vibration produced by a matching of the combustion frequencies with the natural frequency of the treatment system.

Abstract: A charge sensitive amplifier with high common mode signal rejection includes  an NPN bipolar junction transistor (BJT) and a P-channel metal oxide semiconductor field effect transistor (MOSFET) connected in a totem pole circuit configuration. The BJT base terminal receives a dc reference voltage , the MOSFET gate terminal receives the incoming data signal, the MOSFET drain  terminal is grounded and the BJT collector terminal provides the output voltage signal and is biased by the power supply through a resistive circuit  element. The MOSFET operates as a source follower amplifier with the transconductance of the BJT serving as the load at the source terminal, whil e the BJT operates as a common emitter amplifier with the transconductance of the MOSFET providing emitter degeneration. The signal gains of such source follower and common emitter amplifiers are substantially equal and of opposi te polarities. Therefore, any common mode signal components due to common mode input signals present at the input terminals (i.e., the BJT base and MOSFET gate terminals) which would otherwise appear within the output signal are substantially cancelled, thereby resulting in a high degree of common mode signal rejection.
