Abstract: A DOUBLE-ACTING ACCELERATOR FOR USE WITH HYDRAULIC DRILLING JARS       ABSTRACT        A double acting accelerator (1) includes a mandrel (2) arranged in a housing (3) for sliding longitudinal movement. A pair of pistons (89), (111) are positioned radially between the housing (3) and mandrel (2) to form a substantially sealed chamber (88) longitudinally therebetween. Movement of the mandrel (2) in a first direction urges the first piston (89) toward the second piston (111), thereby greatly increasing the pressure of fluid in the chamber (88). Movement of the mandrel (2) in a second, opposite direction urges the second piston (111) toward the first piston (89) to, likewise, greatly increase the pressure of fluid in the chamber (88). Thus, a large amount of energy is stored in the accelerator (1) independent of the relative direction of movement of the mandrel (2) and housing (3).

Title: Inertial rotation sensing apparatus and method
Inventor: WILSON STANLEY EDWARD GEORGE
IPC: G01C21/16
Filed: 1994-03-31
Abstract: An improved electro-mechanical inertial rotation sensor comprising a rotor which spins at substantially constant speed with respect to an inertial frame of reference. A pickoff generates a signal relating the rotational position of the rotor relative to the apparatus. A phase comparator compares this pickoff signal to a reference signal relating the rotational position of the rotor relative to a fixed orientation in an inertial frame of reference, Changes in phase between the two signals indicate changes in orientation of the apparatus with respect to the inertial frame of reference. In one embodiment, the rotor is driven through an Eddy-current coupling and simultaneously braked by an Eddy-current brake, in a matched torque drive. To generate an accurate reference signal, the rotations of the rotor with respect to the inertial frame of reference are accurately determined using parallel measurements from a similar rotor, used as a test rotor. This test rotor is mounted in a pivot and during operation of the apparatus its axis is alternately oriented so that the test rotor's direction of rotation is alternately in the same direction of rotation (as the primary rotor) and in the opposite direction of rotation. In another embodiment, the rotations of the rotor with respect to an inertial frame of reference are determined using an optical rotation sensor mounted within the rotor. In a second mode of operation, a test rotor is used to determine the rotations of a vehicle or a body, such as the Earth, which maintains a substantially constant speed with respect to an inertial frame of reference:

Abstract: A computer-controlled injector (40) of the type having a motor which advances and retracts a plunger (12) located within a syringe housing (10) toward and away from a nozzle located in the front of the syringe to inject fluid into or withdraw fluid out of an animal subject.  Manual motion is induced by operating a manual motion control  (44-48);  the  operator  can manipulate  the  control  to indicate the desired direction and velocity of motion.  The manual motion control also has a locking mode in which manual motion of the plunger will continue once initiated without requiring the operator to continue manipulating the manual motion control.  The injector performs injections in accordance with one of several pre-programmed protocols, and automatically tracks the fluid volume remaining. The injector compensates for plunger extenders found in some partially pre-filled syringes by applying a stored offset value to the computed plunger position.

Abstract: A method is provided for drilling of a well bore portion including a short radius curved section followed by a straight section. A drilling tool is provided having a first portion on which the drill bit is mounted and a second portion carrying the motor with a knuckle coupling therebetween. The short radius curved section is completed using the drilling tool with the knuckle coupling diverting to one side of the bore to steer the drill bit to the other side. After the curved section is complete the drilling is controlled in an accuratelystraight orientation by providing an eccentric collar which is attached onto thedrilling tool at a position adjacent the knuckle portion. The eccentric collar holds the drilling tool at a slight angle less than that during the curved section. Simultaneously with the rotation of the drill bit, the drill string, the tool and the collar are rotated more slowly about the longitudinal axis so as to constantly vary the angle of attack of the drill bit. In one arrangement, prior to attachment of the eccentric collar, a cylindrical or concentric collar is attached for drilling of a first short section of the horizontal portion. In an alternative arrangement, the eccentric collar has two flat sides which allow the collar and tool to rotate in a slightly curved bore without binding.

Title: Shift rail position sensor for vehicle transmission
Inventor: LOEFFLER JOHN M
IPC: F02N11/10
Filed: 1995-02-27
Abstract: A neutral start switch assembly for a vehicle transmission including a case having a plurality of generally parallel shift rails supported therein is disclosed.  Each of the shift rails is longitudinally movable forwardly and rearwardly from a central neutral position to first and second gear engaging positions.  A notch is formed in the outer surface of each of the shift rails.  These notches are aligned with one another when all of the shift rails are in their central neutral positions.  The neutral start switch assembly includes an actuator lever which is pivotably mounted to the transmission case.  One end of the actuator lever cooperates with the notches formed on each of the shift rails.  The other end of the actuator lever cooperates with a neutral start switch mounted on the transmission case.  When all of the shift rails are in their central neutral positions, the actuator lever is moved to a first position.  When any one of the shift rails is moved out of its central neutral position, the actuator lever is moved to a second position.  Such movement of the actuator lever causes operation of the neutral start switch to prevent the vehicle engine from being started unless all of the shift rails are in their central neutral positions.
