Title: Electrical interconnect contact system
Inventor: JOHNSON DAVID A
IPC: H01R12/55
Filed: 1992-01-09
Granted: 2000-07-25
Abstract: A connecting device for integrated circuits or the like.      The disclosed device has a housing interposed between the lead of an integrated circuit and the respective terminal. A slot in the housing extends from one surface of the housing to the oppositely facing second surface. The slots, of which there can be a plurality, extends parallel to the axis of alignment of the lead and the terminal. The first surface has a trough proximate the integrated circuit lead. The second surface has formed therein a similar trough which is near the terminal.      The first mentioned trough receives a rigid first element extending across the slot or slots in which one or more contacts are received. The second mentioned trough receives an elastomeric second element. It also extends across the slot or slots. A planar contact or contacts is or are received in the slot or slots. Each contact has a protrusion to be engaged by an integrated circuit lead. The contact also has a nub normally extending outward from the housing toward the second surface of the housing to engage a corresponding spaced terminal. The contact further has a hook near the nub of the contact, which hook encircles the elastomeric second to hold the contact thereto. There is an elongated channel in each contact for receiving the rigid element. Relative movement occurs as the protrusion of the contact is engaged by, and urged inwardly into the housing by, an integrated circuit lead. The assembly functions as a result of the rigid first element moving relatively along the channel formed in the contact. The protrusion of the contact moves across the integrated circuit lead by which it has been engaged. The nub of the contact moves across the corresponding spaced terminal of the printed circuit board. A number of different embodiments is discussed in the disclosure.

Title: Compensated transition for spacecraft attitude control
Inventor: LIU TUNG Y
IPC: B64G1/38
Filed: 1992-03-04
Granted: 1999-08-03
Abstract: An improved method for transitioning a spacecraft from a thruster (1) controlled, station keeping mode to an operational, on-orbit mode, in which attitude control is maintained using internal momentum wheels (3).  The method first utilizes a thruster compensation technique to supplement the conventional transition mode control system.  This compensation uses empirical thruster data to derate thruster (5) efficiency for extremely short pulse durations necessarily used in transition mode operation.  Secondly, a three step deadbeat thruster (5) sequence is employed in which a first pulse linearizes spacecraft (1) motion prior to orienting and stopping nutation.  This linearization provides improved accuracy in computing and shortens the waiting time for subsequent thruster (5) firings.

Title: Fiber optic cable having spliceless branch and method of making
Inventor: EDMUNDSON GARY WAYNE
IPC: G02B6/00
Filed: 1992-04-03
Granted: 1998-02-24
Abstract: A spliceless optical fiber cable has a main distribution cable having a plurality of optical fibers disposed therein and at least one stub or drop cable extending from the distribution cable at one or more branch points.  The stub or drop cables are configured with the distribution cable in a manner such that no splices are required.  At each branch point, an optical fiber branch module is utilized for protecting the optical fibers from moisture and mechanical damage, providing a strong anchoring point for the stub or drop cable, and insuring that the minimum bend radius is not violated.  The spliceless optical fiber cable is made by accessing the specified optical fibers at a disconnect point along the length of the distribution cable and cutting the specified optical fibers.  At the branch point, the specified optical fibers are again accessed and carefully pulled from within the buffer tube and protective elements of the distribution cable so that a length of the specified optical fibers is disposed outside of the distribution cable.  The disposed length of the specified optical fibers is then inserted into a stub sheath, the stub sheath then being anchored to the optical fiber branch module.  Heat-recoverable material is used to seal the branch point and disconnect point.  Because the optical fiber branch module can be, in some cable configurations, relatively small (an outer diameter of no greater than 1.25 inches and a length of no greater than five inches), the spliceless fiber optic cable, after manufacture, may be wound in reels for subsequent deployment without incurring cable or fiber damage and, further, may be deployed in standard PVC piping having a 1.25 inch inner diameter.  The spliceless fiber optic cable may also be preconnectorized.

Title: Metallization of non-conductors
Inventor: MAHLKOW HARTMUT
IPC: C25D5/56
Filed: 1990-11-27
Granted: 2000-01-11
Abstract: The invention provides a process for enabling direct metallization of nonconductors. Strongly-adherent insoluble polymeric products are deposited in one process step on the surface of the nonconductor from an acidic aqueous solution (optionally containing a solubilizer) of initially-nonconductive oligomers, monomer/oligomer mixtures, or monomers or mixtures of monomers of five-membered heterocycles, by contact with a non-rinsable insoluble coating containing manganese dioxide which has been adsorbed on the surfaces of the nonconductor from a solution containing permanganates. The electrical conductance of the polymeric products is sufficient to permit deposition of metal on the polymer surface from galvanic baths through application of an electrical current.

Abstract: A borehole logging tool is lowered into a borehole traversing a subsurface formation and a neutron detector measures the die-away of nuclear radiation in the formation. A model of the die-away of nuclear radiation is produced using exponential terms varying as the sum of borehole, formation and thermal neutron background components.      Exponentially weighted moments of both the die-away measurements and die-away model are determined and equated. The equated moments are solved for the ratio of the borehole to formation amplitude components of the measurements. The formation decay constant is determined from at least the formation and thermal neutron background terms of the weighted measurement aril model moments. An epithermal neutron lifetime is determined from the formation decay constant. This epithermal neutron lifetime and the amplitude ratio are used by a trained neural network to determine a lifetime correction and an apparent standoff. A standoff corrected lifetime is determined from the epithermal neutron lifetime and the lifetime correction. A porosity log of the formation is produced which is corrected for detector standoff from the borehole wall as a function of the standoff corrected epithermal neutron lifetime calibrated in borehole models of known porosities.

Abstract: A hydraulic rockshaft control circuit which includes a three-way valve that normally operates the rockshaft is connected to the lift cylinder on a trailing implement.  A hitch lock valve connected to the rockshaft control valve maintains the rockshaft in a preselected position regardless of changes in pressure at the valve output.  The extend side of the lift cylinder is connected to the control valve output so that the tractor hitch control is used to operate the trailing implement cylinder.  To overcome the inability of the three-way valve to positively retract the trailing implement cylinder, a reducing/relieving valve is connected to the retract side of the cylinder and is adjusted to provide just enough pressure to retract the cylinder and raise the implement wheels from ground contact when the extend side is connected to return pressure.     A position feedback system on the implement is connected to the hitch control unit (HCU) on the tractor.  When the HCU senses a feedback signal from the implement, the HCU control mode changes from rockshaft control to trailing implement control wherein implement position is set and maintained in a manner similar to that for the conventional rockshaft control. A voltage readout from the feedback signal provides a visual indication of implement position.

Abstract: An electromagnetic confining apparatus prevents the escape of molten metal through the open end of a vertically extending gap between two horizontally extending members, such as two counter-rotating rolls of a continuous strip caster. The molten metal is located between the two members. The apparatus includes a vertically disposed coil through which flows a time-varying electric current to generate a first horizontal magnetic field adjacent the open end of the gap. A time-varying conduction current is directed through the pool of molten metal adjacent the open end of the gap, in a vertical direction opposite that of the current flow in the adjacent portion of the coil. The flow of conduction current through the molten metal pool generates a second horizontal magnetic field adjacent the open end of the gap and which augments the first horizontal magnetic field to provide a repulsive body pressure which urges the pool of molten metal inwardly away from the open end of the gap.
