Abstract: Gas turbine stationary blade is improved in shapes of blade leading edge and fillets, in supporting of inserts and in blowing of cooling air, so that blade cooling efficiency is enhanced, insert supporting structure is simplified and clogging of cooling holes is prevented, thus reliability of the stationary blade is enhanced. Passages (23,24) are provided in stationary blade (10) . Front insert (2) is provided in the passage (23) and rear insert (5) in the passage (5) to be supported at two points of insert supporting portions (3a, 3b), (6a, 6b), respectively. Projection (1) is provided at blade leading edge so that portion where thermal load is high is made smaller in size and number of rows of cooling holes (11a) in this portion is lessened. Air blowing holes (4b) on dorsal side of the front insert (2) and film cooling holes (12) of the blade have diameters larger than those of other holes, so that dusts in cooling air are caused to flow out to prevent clogging of the holes. Curved surface of the blade leading edge is formed to elliptical curve, so that flow of the cooling air is made smooth. Curved surfaces of fillets are also formed to elliptical curve and thermal stress concentration is avoided.

Granted: 2005-10-04
Abstract: L'invention concerne une ferrule optique présentant un évidement (17c), dans lequel est placée une entrée servant au moulage de résine, formée dans un corps de ferrule (11). Selon cet agencement, une coulure (10), laissée après qu'une partie entrée dans l'évidement (17c) du corps de ferrule (11) moulé ait été coupée à l'aide d'un coupe coulée, peut être aisément coupée en profondeur. Il n'y a donc pas de risque de débordement de la coulure (10) hors de l'évidement (17c) à rattraper sur la paroi frontale intérieure d'un boîtier si le corps de ferrule (11) s'adapte au boîtier tel qu'un connecteur optique MPO. Etant donné qu'il n'est nécessaire d'éliminer la coulure (10) par polissage pour améliorer la productivité du corps de ferrule (11), on peut donc réaliser automatiquement un grand nombre de corps de ferrule (11) sans intervention humaine.

Abstract: This invention relates to a method for embedding a multiplicity of discrete masses of material in a resinous coating on a sheet of metal in a coil coating system. The sheet is coated, the masses are embedded in the wet resinous coating, and the coating is dried in a one-pass system. The resinous coating and the embedded masses are preferably resistant to ultra-violet radiation. The wet resinous coating, therefore, is preferably a liquid fluorocarbon resin. The discrete masses comprise pigmented particulate minerals and resins in the form of granules, beads, vesiculated beads, pellets, flakes, platelets, cylinders, coating powders, and coating powder precursor chips. The minerals include glass, quartz, mica, pebbles, and ceramics. The particulate resins include polyesters, acrylics, nylons, polyurethanes, polycarbonates, solid fluorocarbon resins, and solid mixtures of a fluorocarbon resin and an acrylate or methacrylate polymer or copolymer. Sheet metal decorated in such a manner is useful as stock in the manufacture of metal roofing shingles simulating the appearance of traditional asphalt shingles.

Granted: 2007-11-13
Abstract: Electrical equipment (14) is safeguarded from damage due to faults by a circuit that provides several levels of protection. A semiconductor switch (18) and a current sensor (24) are placed in series with the electrical equipment (14). When the current to the equipment exceeds a first threshold for a predefined period of time, the semiconductor switch (18) is rendered non-conductive until the circuit is specifically reset. When the current to the equipment exceeds a greater second threshold, a pulsed signal alternately places the semiconductor switch (18) in conductive and non-conductive states so that the average current applied to the equipment (14) is within an acceptable level. Should the current exceed an even greater third threshold, the semiconductor switch (18) is immediately rendered non-conductive until the circuit is manually reset.

Title: Protective recombinant haemophilus influenzae high molecular weight proteins
Inventor: LOOSMORE SHEENA M
IPC: C12N15/09
Filed: 1999-10-07
Granted: 2012-01-17
Abstract: Protective high molecular weight (HMW) proteins are produced recombinantly by expression from E. coli by using a promoter effective in E. coli and a nucleic acid molecule which contains a modified operon of a non-typeable strain of Haemophilus. The modified operon contains the portion only of the A region which encodes the mature HMW protein and the complete B and C regions of the operon. Enhanced levels of expression of the HMW proteins can be achieved by including the E. coli cer gene, a further copy of the portion of the A region of the operon encoding the mature protein or both, in the expression vector.  Nucleotide and deduced amino acid sequences of the hmw1 and hmw2 genes and HMW1 and HMW2 proteins, respectively, of several non-typeable Haemophilus influenzae strain have been identified.

Title: Ice maker harvest control and method
Inventor: BILLMAN GREGORY M
IPC: F25C1/12
Filed: 2001-08-15
Granted: 2007-10-23
Abstract: The present invention comprises an ice harvest system for use in an ice maker.  The ice maker herein includes a refrigeration system for cooling of an evaporator. Ice is formed thereon as water is pumped by a re-circulating pump to flow from a water distribution tube over the evaporator surface. Water that is not immediately frozen thereon flows into a water pan positioned there below. A pressure fitting is positioned in the pan at the bottom thereof and connected to a pneumatic tube. The pneumatic tube is connected to a pressure sensor located on a control board at a position remote from the water pan. Pressure is communicated through the tube to the pressure sensor as a function of the depth of the water in the pan. This pressure is converted by a microprocessor of the control board for interpretation as a water level in the pan. As the water level in the tray lowers due to the formation of ice, the pressure transmitted to the pressure sensor reduces from a predetermined high or full water level. A harvest point occurs which corresponds to the sensing of a predetermined low water level/low pressure point indicating sufficient ice has formed on the evaporator.

Title: Slotting geometry for metal pipe and method of use of the same
Inventor: SLACK MAURICE WILLIAM
IPC: E21B43/10
Filed: 2001-09-28
Granted: 2010-06-15
Abstract: A slotting geometry for a metal pipe for use in fabricating slotted liners. The slotting geometry includes one or more integral substantially continuous unslotted helical coils extending around a peripheral sidewall for substantially the entire length of a tubular body. There are helical regions between the coils containing slots arranged to create generally trapezoidally shaped elongated struts joining the edges of adjacent coils. Ends of the tubular body have unslotted connecting portions, thereby facilitating connection with the tubular body. Slotted liners fabricated using this slotting geometry have the capability of having their outer diameter expanded or contracted. This has utility when inserting or removing the slotted liners into a well bore. By expanding or contracting the outer diameter, the slots can be made to be wider or narrower, this has utility in controlling slot width.

Par conséquent, on empêche l'augmentation de la résistance due à l'effet de proximité, le câble multiconducteur (1) pouvant être ainsi utilisé comme câble de courant haute fréquence. En l'occurrence, ce câble multiconducteur est bon marché et la finition de ses extrémités est facilitée.
