Patent CA-2215164-A1 (CA)
Title: In-situ oil analyzer and methods using same, particularly for continuous on-board analysis of diesel engine lubrication systems
Inventor: FREESE V CHARLES E
IPC: G01N33/30
Filed: 1996-03-06
Abstract: A method and apparatus for detecting the degree of deterioration of a lubricating oil for an operating machine includes a grid-like capacitive sensor (20) that uses the lubricating oil as a dielectric medium. A magnetic field is imposed upon the oil to attract ferromagnetic wear particles into the vicinity of the sensor. Preferably, the magnetic field is generated by at least two independently controlled electromagnet windings (26, 28) aligned such that the magnetic field produced by each winding acts upon the wear particles. A plurality of capacitance measurements are taken at periodic intervals at each of several magnet operational states for respective classification and analysis. All windings may be simultaneously de-energized for release of captured particles back in to an oil circulation stream and to clean the capacitative sensor grid of accumulated particulates.

Inventor: AUER ERNST
IPC: F16H47/02
Filed: 1998-04-16
Abstract: A hybrid gearbox for land vehicles and automotive machines is designed such that the starting up and maneuvering operations of the vehicles are powered by a hydromotor and their normal travel is powered by a direct coupling with an internal combustion engine.  In its normal operation, the internal combustion engine drives a neutrally positioned axial piston pump as well as the driven shaft.  When operated under load, the driven shaft is decoupled from the internal combustion engine, and the latter drives the variable axial piston pump which in turn delivers pressure to the hydromotor.

Abstract: The Postarm Drill System is a method and pneumatic apparatus used to secure a pneumatic drillin a position to allow it to drill horizontal holes in a rock face in underground operations It is known to have as its main post a hollow tube which has at either end within its hollow a pneumatic cylinder capable of extending outwards in both directions. In this invention a pneumatic control valve is mounted to the main post thus allowing the operator to hold the post in the desired position and by extending the cylinders outward until contact is made with the roof and floor of the mine thus allowing the post to stand freely. In this invention a bracket is attached to the main post dependent upon an air feed motor and chain to cause it to travel the length of the post. The bracket is equipped with a pneumatic clamp allowing for a horizontal arm to be attached to it. On the arm a control valve is mounted thus allowing the operator to manually position the arm in the desired location and lock it into position by means of the pneumatic clamp. In this invention the horizontal arm has attached at its end a bracket allowing a slide rail to be attached for the purpose of mounting the pneumatic drill system upon it. The slide rail has attached to it a fixed back stop in which the pneumatic cylinder of the pneumatic drill system may be attached thus allowing the post drill to be moved forward or back to allow for the rubber bumper to make contact with the rock face. The chain and feed motor system now allows the operator to raise or lower the drill to the desired location then move the drill forward until contact is made with the rock face. By means of the remote control console the operator can now stand clear and drill the desired hole.
