Granted: 2008-04-29
Abstract: An actuator assembly for an electrical power switch apparatus, the actuator assembly having a housing and a plunger positioned within the housing where the plunger is movable between a set position and an actuated position. The plunger includes a compression spring to provide a pre-load thereto that biases the plunger away from the set position and toward the actuated position. A magnet contained in the housing and positioned proximate to the plunger establishes a magnetic force which overcomes the pre-load of the compression spring and maintains the plunger in a set position. A coil assembly, that when energized, produces an electromagnetic force which bucks the magnetic force established by the magnet allowing the plunger to be propelled by the compression spring to the actuated position. A screw extends through an opening in the plunger for engagement with the compression spring so that rotation of the screw results in the adjustment or calibration of the pre-load of the compression spring.

Title: Process for production of cement
Inventor: SERI NAOKIYO
IPC: C04B7/44
Filed: 1998-09-03
Granted: 2004-02-24
Abstract: ABSTRACT        Disclosed herein is a process for producing cement which can reduce the content of hexavalent chromium in cement clinker without impairing the quality of the cement clinker. An atmos-phere in which the oxygen concentration is comparatively low is formed by adding a combustible material to the object to be burnt in the region from the position about four times the internal diameter of the rotary kiln away from the outlet side to the inlet of the rotary kiln, or to the object to be burnt at the inlet of the clinker cooler 4, thereby forming. The combustible material is one which burns as fast as or more slowly than the main fuel, and is coarser than the main fuel.

Abstract: A specific region of chromosome 10 (10q23.3) has been implicated by series of studies to contain a tumor suppressor gene involved in gliomas, as well as a number of other human cancers. One gene within this region was identified, and the corresponding coding region of the gene represents a novel 47 kD protein.  A domain of this product has an exact match to the conserved catalytic domain of protein tyrosine phosphatases, indicating a possible functional role in phosphorylation events. Sequence analyses demonstrated that a number of exons of the gene were deleted in tumor cell lines used to define the 10q23.3 region, leading to the classification of this gene as a tumor suppressor.  Further analyses have demonstrated the presence of a number of mutations in the gene in both glioma and prostate carcinoma cells. Methods for diagnosing and treating cancers related to this tumor suppressor, designated as TS10q23.3, also are disclosed.

Title: Resilient electrical interconnects having non-uniform cross-section
Inventor: GOODWIN JONATHAN W
IPC: H01R13/24
Filed: 1999-12-24
Granted: 2004-11-02
Abstract: Resilient electrical interconnects are provided which have a non-uniform cross section which achieves an increased range of deflection and a predetermined relationship between compression force and deflection of the interconnect, and between resistance and deflection of the interconnect. A smaller cross sectional area decreases the spring rate, or compression force, of the interconnect during compression.      Increased range of deflection and reduced spring rate enables improved compensation for surface irregularities and facilitates mounting of integrated circuit or other devices having large arrays of interconnects. The non-uniform cross section is provided by a single or compound slope, or alternatively a nonlinear curve, from the end of smaller cross-section to the end of larger cross-section.

Filed: 1998-07-28
Granted: 2005-10-18
Abstract: A method is provided for producing an ultra-high strength steel having a tensile strength of at least about 900 MPa (130 Ksi), a toughness as measured by Charpy V-notch impact test at -40 °C (-40 °F) of at least about 120 joules (90 ft-lbs), and a microstructure comprising predominantly fine-grained lower bainite, fins-grained lath martensite, or mixtures thereof, transformed from substantially unrecrystallized austenite grains and comprising iron and specified weight percentages of the additives: carbon, silicon, manganese, copper, nickel, niobium, vanadium, molybdenum, chromium, titanium, aluminium, calcium, Rare Earth Metals, and magnesium. A steel slab is heated to a suitable temperature; the slab is reduced to form plate in one or more hot rolling passes in a first temperature range in which austenite recrystallizes; said plate is further reduced in one or more hot rolling passes (10) in a second temperature range below said first temperature range and above the temperature at which austenite begins to transform to ferrite during cooling; said plate is quenched (12) to a suitable Quench Stop Temperature (16); and said quenching is stopped and said plate is allowed to air cool (18) to ambient temperature.

Inventor: GRAMS DAVID W
IPC: B32B27/08
Filed: 1998-07-21
Granted: 2008-01-08
Abstract: In the packaging of a wide variety of products in flexible film bags, problems with edge tear and incompleted bag cut-off have been encountered. The edge tear and incomplete cut-off are worse for films containing low melting polymers, such as metallocene-catalyzed ethylene/alpha-olefin copolymers. These problems can be solved using a clamp-cut-seal process, as opposed to a clamp-seal-cut process.  By cutting before sealing, the film is still cool, and the strain on the film due to the cutting does not pull on the seal area enough to cause edge tearing (i.e., tearing at the seal). The higher resistance to elongation of the cool, clamped film also serves to reduce or prevent incomplete bag tail cutoff. Also, by providing a means for sealing which clamps the film before it is cut, defective seals from bag "pull back" can be avoided.
