Title: Thermally controlled equipment cabinet
Inventor: BEATY ROBERT CARROLL
IPC: H01M50/251
Filed: 1991-05-01
Granted: 1996-06-04
Abstract: A thermally controlled equipment cabinet for telephone systems has a gas-tight, sealed compartment for mounting sensitive active electronic components and has jacket 20 partially encompassing at least three sides of the sealed compartment.  The sealed compartment utilizes either forced or natural convection to dissipate the heat generated by the components to the surrounding air.  The heat is then dissipated to the ambient air through a highly heat-conductive corrugated roof and side panels.  The jacket provides a cooling air passage around the sealed compartment and over the corrugated roof removing heat thereof.  Nonsensitive passive components, mounted in the cooling air passage near the air inlet of the jacket, provide protrusions in the cooling air passage causing a slightly turbulent air flow in the passage thereby enhancing heat transfer.  Storage batteries, such as used in telephone systems, are mounted within the cooling air passage near the air exhaust of the jacket.  The warmer air allows the batteries operate at higher and more efficient operating temperatures.

Title: Pneumatic method and apparatus for seating tubeless tires
Inventor: OCHOA SANDY
IPC: B60C25/12
Filed: 1991-08-20
Granted: 1995-05-09
Abstract: A  method  and  apparatus  for  seating  tubeless  tires, particularly large tubeless truck tires, on a rim.  A tank having a volume related to the internal volume of the largest tire to be seated is charged with compressed air at a pressure which is within the range of pressures considered safe for general purpose vehicular applications.  A discharge barrel having an internal passage with an area of from 8 to 20 square centimeters is disposed between the tank and the bead of the tire and positioned so that air discharged therefrom strikes the bead from a direction roughly perpendicular to the plane of the bead.  An approximately full-flow valve, positioned in flow control relationship to the barrel, is opened abruptly to direct a pneumatic pulse having a fast-rising leading edge against the bead.  The bead then seats on the rim as a result of the combined effect of the motion imparted thereto by the impact of the pulse and the air injected into the tire in connection with that impact.

Title: Alumina coating for the protection of stainless steel
Inventor: CAPUANO GUIDO A
IPC: C25D9/10
Filed: 1991-09-23
Granted: 1998-08-18
Abstract: An alumina coating, produced by aluminium electroplating of a stainless steel containing from about 0.02 to about 0.2% of misch metal or 0.2 to 0.8% of titanium, improved the oxidation resistance in air of these stainless steels at least up to 1100°C. In thermal cycling tests carried out between 1000°C and room temperature, these steels maintained an excellent adhesion matrix-coating, for at least up to 500 cycles. In fact, the addition of misch metal or titanium in stainless steel provided good bonding between coating and matrix. The porous nature of thealumina coating was found very beneficial because it favors the absorption of the thermal and growth stresses.

Title: Moving picture receiving method and apparatus
Inventor: SAITO TAKU
IPC: H04N19/00
Filed: 1993-02-25
Granted: 1999-12-28
Abstract: A method and apparatus are presented for compensating for lost blocks of image data in transmitted signals, for instance television signals. The method involves a series of steps performed in the receiving apparatus alone. The first step is the detection of a lost image data block. Then an average value is calculated for each data block adjacent to the lost data block, and an average value is also calculated for each data block at those same positions in the preceding frame. A difference value between the pair of average values for each of the respective block positions is determined, and compared to a predetermined threshold value. The lost data block is replaced by either the average value of the adjacent data blocks in the same frame or by the corresponding data block in the preceding frame, the choice depending upon the difference values determined.

Abstract: Process for incorporating, in the porosity of a catalyst for processing hydrocarbons, a sulphurising agent chosen from the group consisting of elemental sulphur and organic polysulphides with the aid of a solvent, the process being characterised in that the solvent contains wholly or partially a constituent of the olefin or olefinic cut type, for example of the vegetable oil type, or a similar constituent. The use of such a constituent makes it possible to reduce appreciably the exothermic effect (for example curve 4 of the figure), which is produced during the presulphurising, in comparison with the exothermic effects obtained without the use of such a constituent (for example curve 1). <IMAGE>

Abstract: A microwave radar antenna that substantially comprises molded or extruded thermoplastic components that are assembled into completed assemblies, are then metallized by either electroless copper or are electroplated with copper to achieve RF conductivity. The finished subassemblies are joined together forming the completed antenna. The molded, metallized, plastic antenna uses a thermoplastic material, such as polyetherimide, or suitable high strength, high temperature thermoplastic that is used to injection mold or extrude detailed microwave components. The molded components are assembled, using epoxy adhesives, solvents or other mechanical method into microwave subassemblies. These subassemblies are then either electroless copper plated or electroplated to provide RF conductivity. The metallized subassemblies are then joined together using mechanical methods to form a completed radar antenna,replacing heavier more costly metal radar antennas. Specifically, the molded, metal-lized, plastic antenna is comprised of an antenna aperture and electromechanical phase shifter section, centerfeeds comprising a horizontal feed network, interconnecting waveguides, a vertical feed network including conventional rotary field phase shifters, and a sum and difference monopulse feed network. The antenna also includes a suit-able beam steering controller that provides electronic antenna beam steering and power supplies. The use of the present microwave antenna incorporating molded, metallized, plastic components results in an antenna having better performance, lighter weight, and much lower manufacturing costs than conventional metal antennas.

Abstract: A method is provided for identifying and locating curves within a digitized image. Digitized images are comprised of points which may represent curves stored as an array of binary coded elements in an memory device. Each addressable memory location in the array represents a single point or pixel. Particular curves within a scanned image are identified by randomly selecting a minimal subset of points which are necessary to generate a general equation for that curve; the equation along with a point on the curve is then used as in input parameter to an incremental curve generation routine which incrementally generates all points which are in a path along that curve. A comparison is made with scanned data to determine how many points exist along the path. This is repeatedly done until the curve with the greatest number of points is located.
