Abstract: Abstract of the Disclosure An integrated hydraulic quick change side tilting coupler for attaching and detaching a tool for use on wheel and track loaders and material handlers.  A coupler frame is hingedly mounted at the end of the loader arm for swinging in a vertical plane actuated by the loader hydraulic system.  A radius plate on the frame has an upwardly projecting curved rim adapted to engage two bear-ing points on the tool for mounting and dismounting the tool.  A central pivot pin projects forwardly from the frame and fits a bore in the tool. The axis of the pin is on the focal point of curvature of the plate permitting pivoting of the tool and consequent side-tilting of the tool about that axis.  When the frame is coupled to the tool the upper portion of the plate is locked in a retainer at the top rear of the tool.  A pair of locking and tilt cylinders is mounted on the frame, their rods carrying trunions which are retracted and extended thereby.  The trunions cooperate with locking pivot pins which extend rearwardly from the lower rear face of the tool.  These pins are rotatably engaged in the trunions when the rods are extended and released when they are retracted.  Hydraulic control means are provided for retracting and extending the rods for coupling and uncou-pling and for simultaneously extending one rod and retracting the other for tilting the tool in either direc-tion about the central pivot pin.  Thus the same pair of cylinders performs both the functions of locking and unlocking the tool for coupling and de-coupling and of tilting the coupled tool either way.

Granted: 1994-04-26
Abstract: Abstract of the Disclosure An improved fiber glass manufacturing apparatus has an improved fiber glass bushing control system.  One aspect of the system has a weighing means for weighing complete collections of glass fiber strands produced from forming from a bushing through attenuation, a monitoring means for the time of attenuation at constant strand speed and a program computer means that receives signals from the weighing means and the monitoring means.  The program computer means has a means for establishing a database of the weights and times, a means for determining the throughput of the glass from the bushing from the weights and times, a means for determining average throughputs and including these averages in the database, a means for comparing the average throughputs to a standard set throughput, and a means for initiating an adjustment to the main bushing temperature controller.  When the average throughput deviates from the set point throughput by a value greater than the sensitivity factor of the bushing.  Also, the improved system has circuit means for carrying the adjustment signals to the controller and to the bushing for a temperature change.  Also, the improved system can have a second bushing controller connected across two sections of the bushing to regulate relative current flow in the two sections in order to control the amount of fiber produced by each section and the program computer means additionally has a means for determining the difference in throughputs between collections of strand produced from each section of the bushing at the same time and placing these difference values in the database, and a means for averaging the difference values, and a means for comparing the difference values to determine if they are other than the value of zero, and a means for adjusting the segment bushing controller to achieve average difference value in throughput other than zero.  Also, both aspects of the control system can have a means for redetermining throughput values previously determined prior to an adjustment to incorporate a factor for the adjustment.  Also, both aspects can have a means for determining an upset condition along with a means for ignoring previously determined throughput values and starting the determination of throughput values anew.

Abstract: Abstract of the Disclosure A current ratio device for use in constructing a current transformer comprises A first magnetic core, a second magnetic core, a measuring winding electro-magnetically coupled with the first core but not with the second core, and a compensating winding electromagnetically coupled with both cores. An externally powered amplifier has its input connected to receive the voltage waveform across the measuring winding.  Its output provides a compensating current through the compensating winding equal to a magnetizing current required to magnetize the second core.  The amplifier output also provides a measuring current through the measuring winding in the direction opposite that of the compensating current and equal to the compensating current multiplied by the ratio of turns in the compensating and measuring windings,  This device-is a self-contained article of commerce that, when electromagnetically coupled (without electrical connection) to conventional primary and secondary windings and a burden, provides a current transformer with improved qualities.  In particular, the magnetizing current needed by the transformer is provided by the separate current ratio device, thus avoiding the error inherent in current transformers that arises from the need to supply the magnetizing current from the primary circuit.  Another disclosed feature is the ability to examine the waveform of the magnetizing current and in particular to detect the presence of even harmonics and hence a probability of direct current in the primary circuit.

Title: Drill string element
Inventor: LARSSON KENNETH L
IPC: E21B7/20
Filed: 1989-04-25
Granted: 1993-04-13
Abstract: Abstract The present  invention relates to a drill  string element adapted to be coupled to other similar drill string elements by thread connections (19) thus forming a drill string for top hammer drilling.  Each drill string element includes at least one rod (15;15';15") for transferring impact energy to a drill bit (11) provided at the lower end of the drill string (10) and a tube assembly (21;21';21") for transferring rotation to the drill bit (11), said tube assembly surrounding the rod. When handling drill string elements of the above-mentioned type it is extremely important that this handling can take place in a safe way without any risk for accidents during operation  working site.    Previously  known  drill  string elements of the type in question have the disadvantage that the rod can fall out of the tube assembly in one direction. Also the accessibility to the interior of the drill string element in connection with repairs/service must be considered and  the  drill  string  elements  must  stay  intact  during operation, especially when they are unscrewed from each other. The invention is characterized by that the tube assembly (21;21';21")  in  the  area  of  the  two  ends  of  the  rod (15;15';15") is provided with an internal diameter reducing (27;27',27";27'''), and that the rod (15;15';15") is provided with cooperating radial projections (28;28') or shoulder means (28"). Also the tube assembly (21;21';21") includes at least two tubular members  (18;18';18")  that are coupled to each other by a thread connection that is harder to unscrew than the thread connection (19) for coupling together the drill string elements.
