Inventor: KUMAR SUDHIR
IPC: B61K3/02
Filed: 1989-11-21
Abstract: In railroad operations, a method and apparatus for optimizing on-board rail lubrication for both curved and tangent track. The apparatus is mounted on the car body of the last locomotive of a locomotive consist behind the last axle. A lubricating device applies two different lubricants, one on the crown of the rail and the other on the gage side.      The amount and type of the crown lubricant are chosen such that the crown lubricant is totally consumed by the passage of the train wheels. The amount of application of the two lubricants is controlled by a microprocessor. A new sensor has been devised which measures degree of rail curve and estimates the angle of attack of the wheel on the rail by converting lateral displacement into either of the two quantities. This value is provided to the microprocessor.      Other sensors measuring speed, temperature, humidity, etc. provide input signals to the microprocessor. This invention not only reduces the friction coefficient between the wheel flanges and the rail but also reduces the forces between the wheel flanges and the rail. Both rail and wheel wear are reduced while simultaneously also reducing the fuel consumed in the train.

Patent CA-2007193-A1 (CA)
Inventor: DENKER STANLEY D
IPC: B65G47/244
Filed: 1990-01-04
Abstract: A conveyor system which receives products in random order at its infeed end and delivers product in a serial  aligned order at its  outlet end.  The  conveyor system  comprises  first  and second endless  belt conveyors  which are  longitudinally aligned and positioned  such that  the product exiting the first conveyor is received on the second conveyor.  The first  conveyor is  of a greater width than the second and at the location where they meet is  a  third  endless  belt  conveyor   moving  in   a  direction perpendicular to  the longitudinal  flow direction  of the  other two.  The machine that feeds  products to  the first  conveyor is set at  a desired  product flow  rate in  terms of  products-per-minute and the speed of the first conveyor is set to  handle that capacity.   The second  belt is  driven at  a speed  equal to  or greater  than the  product-per-minute  rate  times  the  product length.  As misaligned products flowing on the first conveyor are intercepted by  the transversely  positioned third  conveyor, the products are  rotated as  they are urged onto the second conveyor so that the length dimension of the products is generally aligned with the second conveyor.

Inventor: YOUNG DAVID E
IPC: E21B25/14
Filed: 1990-04-19
Abstract: A coring tool comprises a core cutting section and an actuating section disposed thereabove. The core cutting section includes axially telescoping outer and inner barrels. The inner barrel includes a jaw carrier which carries pivotable core-catching jaws normally covered along their radially inner sides by a driver sleeve. When the driver sleeve is raised by the actuator section the jaws are uncovered. Thereafter, the driver sleeve raises the jaw carrier to bring the jaws into contact with a stationary inclined jaw-deflecting surface to force the jaws laterally inwardly through the core. The actuator section relies upon fluid pressure to release for movement a vertically risible member which is mechanically lifted by a drill string to transmit vertical forces to the driver sleeve from a drill string.

Abstract: A current comparator bridge for measuring the value of an unknown capacitor includes a current comparator having a first comparator winding with an adjustable tap which is connected to one side of a standard capacitor and a second comparator winding connected to one side of an unknown capacitor, a high voltage source being connected to the other side of the capacitors.  The current comparator is provided with a detection winding for detecting when the ampere-turns in the first and second comparator windings are equal and opposed to each other.  In addition to the current through the standard capacitor being applied to the first comparator winding, the bridge includes a circuit to add a current through a standard conductance to the first comparator winding as well as circuits to compensate for errors.  The detection winding is connected to a current-to-voltage converter with an adjustable gain which provides a signal to a phase sensitive detector. A reduced replica of the high voltage source is also applied to the phase sensitive detector which provides output signals Eo and Eqo to indicate when the bridge is balanced for both in phase and quadrature components respectively.     The values of the capacitance and dissipation factor for the unknown capacitor can then be determined from the balanced condition of the bridge which is designed so that it can be automatically controlled by a microprocessor and switch controller.

Abstract: ABSTRACT OF THE DISCLOSURE An adjustable bent sub for use in earth drilling.   The bent sub has a tubular mandrel with an offset axis which is telescopically received in a tubular housing with an offset axis.  By rotation of the mandrel in relation to the housing an adjustment may be made in a bend created by the cumulative effect of the offset axis of the mandrel and the offset axis of  the  housing.   A  longitudinal  stop  limits  longitudinal displacement of the mandrel within the housing.  The mandrel is longitudinally slidable within the housing between a first position wherein further displacement toward the second end of  the housing is  limited by the  longitudinal stop and a second position wherein the mandrel is displaced toward the first  end  of  the  housing.    A  rotational  stop  prevents relative rotation between the mandrel and the housing when the mandrel is in the first position and allows such relative rotation when  the mandrel  is  in  the  second position. rotator acts between the mandrel and the housing, reacting to longitudinal displacement between the mandrel and the housing to cause a predetermined amount of relative rotation between the mandrel and the housing when the mandrel  is displaced from the first position to the second position and returned to the first position.  A split ring locks the mandrel in the first position.
