Title: System and Method for Maintaining Plural Driven Components at Reference Positions
Inventor: ANDERSON KEVIN J
IPC: B66C9/16
Filed: 1994-12-20
Abstract: The disclosure involves a machine, e.g., a portal crane, having two components such as bridge support legs or rail-riding trucks.  Each component is driven by a separate motor and each is moving at a speed, perhaps a different speed.  A method for maintaining the speeds of the two components substantially equal to one another includes the steps of providing a differential signal representing a difference between the speeds of the two components and generating an equalizing signal reducing the speed of the higher-speed component.  Preferably, a second equalizing signal is also generated to increase the speed of the lower-speed component.  A new drive system is also disclosed.  The method and system are particularly useful for maintaining the "squareness" of a double-leg portal crane.

Inventor: LESAGE MICHEL
IPC: G01S17/931
Filed: 1995-01-20
Abstract: To prevent a collision between first and second mobiles, such as travelling cranes, on a common movement path, a method implemented  in the  first mobile  entails  measuring  a  first distance between the first mobile and an origin in a fixed system of axes and a second distance between the first and second mobiles. The method comprises the steps of determining a first speed of the first mobile in the system of axes and a second speed of the first mobile relative to the second mobile in order to deduce a third speed of the second mobile in the system of axes, then of estimating a safety margin between the first and second mobiles, then of comparing the safety margin with a threshold to generate a  collision risk  factor,  and finally of deciding on an action at drive motors of the first mobile as a function of the sign of the first, second and third speeds and the collision risk factor.

Abstract: A top phase transmission line and bottom phase transmission line are stretched between support steel towers so that the bottom phase transmission line is positioned below the top phase transmission line. Each of the transmission lines has at least two conductors, which conductors are arranged to be substantially parallel and are separated by a substantially constant distance by interconductor spacers. An intermediate phase transmission line may be arranged between the top phase transmission line and bottom phase transmission line as well. Such transmission lines are multiconductor transmission lines. In these multiconductor transmission lines, the conductor positioned at the left side in the top phase transmission line and the conductor positioned at the right side in the intermediate phase transmission line or bottom phase transmission line directly below it are connected by a first interphase spacer made of an insulator. Further, the conductor positioned at the right side in the top phase transmission line and the conductor positioned at the left side in the intermediate phase transmission line or bottom phase transmission line directly below it are connected by a second interphase spacer made of an insulator. By this, galloping in the transmission lines can be suppressed.

Title: Plug-in fuse and method of manufacture
Inventor: SIERRA FRANCISCO J R
IPC: H01H69/02
Filed: 1995-03-22
Abstract: A method of manufacturing fuses comprising providing a mold including a mold cavity defining a conductive fuse element having a fuse link, a pair of conductors integrally connected to the fuse link, and a support for holding the conductors to prevent damage to the fuse link. The method further includes melting a conductive material such as a zinc alloy, injecting the material into the mold cavity, and cooling the material to form a conductive element for a fuse. A cover is secured to the conductive element and securely engages the pair of conductors, after which the support is removed. Notably, the removed support and also defective conductive elements can be remelted and reused in the molding process. Also, the alloy composition can be adjusted on-site to yield optimal physical and electrical properties and to minimize material cost. Optimally, features such as retaining barbs, wire connectors and identifying indicia are integrally molded as part of the conductive element to reduce subsequent assembly and post-molding processing. Articles including the above noted features are also disclosed and claimed.

Title: Electrical circuit card with reduced emi emission
Inventor: PETITPIERRE ERIC M
IPC: H05K9/00
Filed: 1995-06-01
Abstract: An electrical circuit card adapted to be inserted into a grounded, electrically conductive housing comprises and insulative circuit board, an insulative faceplate coupled to the circuit board along the front edge thereof, and an electrically conductive shielding strip or shunt located behind the faceplate for reducing EMI emissions from the circuit card. The shielding strip comprises an intermediate portion extending generally vertically along the rear surface of the faceplate, and upper and lower contacts adapted to be brought into electrical contact with the housing when the circuit card is inserted into the housing. At least one of the upper and lower contacts is arranged to be brought into contact with a non-outwardly facing surface of the housing, such as the edge of a designator strip located above or below the opening in which the circuit card is received. The use of a non--outwardly facing housing surface for making contact with the shielding strip simplifies the manufacture of the designator strip by eliminating the masking step necessary to provide a bare metal contact area, improves the appearance of the finished designator strip while allowing more space for printed indicia, and affords a contact surface which is less likely to accumulate dirt and other contaminants.

Filed: 1995-07-28
Abstract: For a slider having convex curvature along its length, or "crown", a method for reducing fly height variation due to crown by shifting the peak of the crown toward the leading end, and the resultant slider structure.  In a preferred method, peak shifting is accomplished in a slider with symmetrical crown by affixing a suspension to the bonding surface of the slider near the leading end.The bonding process creates a displacement force upon the slider to effect the shift.  An alternative approach reshapes a row of sliders prior to rail shaping,e.g., by sand or bead blasting.

Title: Composite nozzles for rock bits
Inventor: LARSEN JAMES L
IPC: E21B10/61
Filed: 1995-10-03
Abstract: A composite mini-extended nozzle is disclosed that is designed to both resist erosion and be strong enough to withstand the shock of a downhole drilling environment. In addition, means are provided to shroud at least a portion of the extended nozzle to further protect a portion of the nozzle nearest the exit plane from downhole obstructions. A combination of materials used to form the nozzle may include a matrix of tungsten carbides with suitable binder joined to an outer metal jacket nozzle body. A third ceramic matrix material may be utilized to line or partially line an interior passage formed by the mini-extended nozzle and a reduced in diameter portion of the nozzle design may include a built-in fracture plane in the unlikely event the end of the nozzle hits an obstruction. The extended portion of the nozzle will shear off along this fracture plane thereby preventing a nozzle washout that likely would result in a trip out of the hole to repair the resultant damage to the rock bit.

Abstract: A portable electronic test instrument is adapted for the automatic testing of semiconductor diodes regardless of the orientation of the diode relative to the test probes. The test instrument supplies an a.c. sine wave test voltage coupled to the test probes. The maximum negative voltage and the maximum positive voltage are measured and compared against a set of predetermined open and short circuit values to obtain a decision of open, short, or ok for each value. The combination of the two comparisons is used to determine the device status according to a decision criteria. The diode status is accordingly displayed on the graphical display of the test instrument, indicating the device is open, shorted, a diode with a forward orientation or a reverse orientation with respect to the test probes, or of an unknown type. The diode forward bias junction voltage is displayed regardless of its orientation.
