Title: Low nox burner
Inventor: FLANAGAN PAUL
IPC: F23D14/26
Filed: 1991-10-23
Granted: 1998-01-20
Abstract: A  method  of  operating  a  burner  to  reduce  the NOx emissions produced  thereby  is  disclosed.  Air and gas are premixed  in  a   manner such  that  excess air exists in the resulting   mixture  and  the  velocity  of  the  mixture  is increased  as  it  passes  through the burner.  By increasing the  velocity  of  the  air/gas mixture, the "residence time" associated  with  the  formation  of  the flame is decreased, i.e.,  the  combustion  gases are in the reaction zone of the flame  for  a  significantly shorter period of time, reducing the  production  of  NOx.  In order to prevent the flame from "lifting-off"  the burner because of the high velocity of the air/gas  mixture, flame stabilizing devices or techniques are utilized   resulting   in  a  high  heat  flux  and  low  NOx production.

Title: Drug injection apparatus for an animal
Inventor: VANDERSTEEN DOUGLAS G A
IPC: F42B12/54
Filed: 1992-12-30
Granted: 2003-10-14
Abstract: A remote injection device for animals comprises a barrel with a piston slidable within the barrel from an initial retracted position at one end of the barrel forwardly toward the opposed end of the barrel to discharge liquid in an injection action through a needle at the forward end of the barrel. The piston is held in a retracted position by an O-ring on a release member which projects through an O-ring carried on the inside surface of the barrel. The inner diameter of the O-ring on the barrel can be adjusted by axial movement of the pair collars on the inside of the barrel. This adjusts the amount of force necessary to push the release member O-=ring thorugh the outer O-ring to release the piston to be moved by spring to the discharge position. The barrel can be mounted either upon an arrow type projectile so the impact forces are sufficient to release the piston upon engaging the animal. Alternatively the barrel can be mounted upon a pole with the pole acting to release the piston when pushed forwardly with the needle and barrel in engagement with the animal.

Granted: 1996-07-30
Abstract: A spring-applied, pressure-released parking brake is controlled by an electrohydraulic control system.  A solenoid operated parking brake control valve and a manually operated tow control valve control communication between the engine driven pump, the sump, the operator driven pump and the release chamber of the parking brake so that the parking brake can be released and applied during normal operation of the engine driven pump and so that the parking brake can be released by operation of the operator driven pump when the vehicle is shut down.  A transport sump valve and an inlet check valve operate to prevent the parking brake from engaging while the vehicle is moving too fast, as a result of operator error, hydraulic failure or electrical failure.

Title: Phase difference measuring apparatus and method
Inventor: YAMAGUCHI SEIJI
IPC: G01S17/36

Granted: 1999-06-29
Abstract: A phase difference measuring apparatus of the present invention obtains a first receive signal by transmitting and receiving a to-be-measured material in a reference state and a second receive signal by transmitting and receiving a signal wave to and from that material in a measured state.  The apparatus finds a reference phase difference .THETA.1 from the transmit wave and first receive signal and an apparent phase difference .THETA.2' from the transmit wave and second receive signal.          The apparatus adds the apparent phase difference .THETA.2' to a product of the number of rotations, n, the apparent phase difference .THETA.2' passes through a given reference point and an angle of 360° to find a true phase difference .THETA.2.  The apparatus varies the number of rotations, n, to n+1 when the apparent phase difference .THETA.2', while being increased, passes through the reference point and that number of rotations, n, to n=n-1 when the apparent phase difference .THETA.2', while being decreased, passes through the reference point.
