| 20090026761 | Elliptical Flow Conditioning Pipe Elbow - A pipe elbow for conditioning the flow of fluid through the elbow so that separate flow conditioners or a flow straightener need not be inserted between the elbow and a flow measurement device, comprising, a fluid carrying conduit elbow having first and second ends of circular cross section for connection to straight piping and having a bend intermediate the ends, wherein a lateral cross section of the conduit at the bend is elliptical in shape. | 01-29-2009 |
| 20090230674 | Fuel Port Elbow Having a Truncated Conductive Insert Tube - A fuel port elbow composed of a plastic port body overmolding an electrically conductive, truncated insert tube such that there is no external dissimilar materials boundary. The tube has a tube first segment, a tube elbow segment and a tube second segment truncated such that the dissimilar materials boundary at the tube truncation is internal to the port body. A port body is integral with the plastic of a flange cover, and overmolds part of the tube first segment and all of the tube elbow and second segments. The port body has a port body second segment having a port body passage communicating with the tube passage and extending remotely from the tube truncation, being adapted for connecting with a fuel line. | 09-17-2009 |
| 20080231048 | PNEUMATIC SWIVEL ELBOW - A pneumatic swivel elbow is provided according to the invention. The pneumatic swivel elbow includes an internal passage extending through the pneumatic swivel elbow and substantially changing in direction. The pneumatic swivel elbow further includes a male coupling portion formed on one end and adapted to be sealingly inserted into and engaged with a corresponding bore of a mating component and being configured to sealingly rotate within the corresponding bore. The pneumatic swivel elbow further includes a conduit coupling portion formed on a substantially opposite end from the male coupling portion. The conduit coupling portion is configured to sealingly receive a pneumatic conduit and is configured to allow the pneumatic conduit to rotate within the conduit coupling portion. | 09-25-2008 |
| 20110241334 | DISCHARGE ELBOW PROVIDED WITH GUIDE VANES - A discharge elbow provided with guide vanes comprises an elbow of rectangular cross section and magnification f of 1| 10-06-2011 | |
| 20110018256 | METHOD FOR LINING A PIPE OR ELBOW - A method for enabling a lining ( | 01-27-2011 |
| 20080217911 | ONE-PIECE ELBOW HYDRAULIC FITTING DESIGNED FOR ELECTRIC ARC STUD WELDING - A hydraulic port weld stud that includes a stud portion having a longitudinal axis and a first bore formed along the longitudinal axis less than an entire length of the stud portion. A port portion extends along an axis transverse to the longitudinal axis of the stud portion. The port portion includes a second bore extending along the transverse axis and intersects the first bore of the stud portion. The port portion and stud portion are integrally formed without the need for a joining or welding operation. | 09-11-2008 |
| 20120038148 | Shallow angle elbow - An elbow has an elongated inlet, an elongated outlet tube that merges with the inlet at a shallow angle, and an endwall opposite the inlet. The round inlet receives product and leads to a first chamber with a rounded bottom. Opposite the bottom, the inlet has a pitch at the transition to the outlet tube. The outlet tube continues upwardly from the pitch to an exit. Within the outlet, a third chamber extends from the first chamber. The first chamber and the third chamber intersect at the second chamber that provides a transition to the flow of product from the first chamber to the angle of the third chamber. Within the second chamber, conveyed product forms a shallow eddy so that additional product flows over the eddy enroute to the outlet. | 02-16-2012 |
| 20110316271 | NICKEL-BASE RADIANT TUBE AND METHOD FOR MAKING THE SAME - Nickel-base radiant tube includes straight and curved elbow tube sections. The straight tube section has constant inner and outer radii. The elbow tube section has a constant inner radius and variable outer radius. The inner diameter of the elbow tube section is equal the inner radius of the straight tube section. Mating end portion of the elbow tube section has an outer radius equal to the outer radius of the straight tube section. Method for making the radiant tube comprises the steps of positioning a mating end portion of the straight tube section adjacent to and aligned with the mating end portion of the elbow tube section so that end faces of the straight and elbow tube sections face each other to define a circumferentially extending weld groove, and butt welding the mating end portions of the straight and elbow tube sections together at the weld groove. | 12-29-2011 |
| 20120074687 | PIPE FITTING APPARATUS - The present invention is an improvement in conventional street elbow pipe design that allows for the street elbow pipe to be easily installed, removed, maintained, adjusted and handled without damage to the street elbow pipe itself or injury to a person performing work on the street elbow pipe. The street elbow pipe includes male and female fitting portions and a nut section disposed around at least one of the male and female fitting portions with a graspable surface area formed on the nut section. | 03-29-2012 |
| 20120223519 | PIPE JOINING STRUCTURE - An object of the invention is to provide a pipe joining structure which allows the parts cost to be reduced while requiring a reduced number of seal portions. In order to accomplish the object, the invention provides a pipe joining structure | 09-06-2012 |
| 20110309612 | DRYER DUCT ELBOW - A dryer duct elbow for attachment between a dryer vent and flexible ducting, or between flexible ducting and a wall vent, may include a first larger end, containing threading and a groove containing an O-ring, and a second tapered end, having circumferential threading and a groove containing an O-ring. Either end is capable of rotational sealing engagement with the flexible ducting, or with frictional engagement with the dryer or wall vents. The dryer duct elbow is formed of two halves which are connected together at the edges to form one elbow. | 12-22-2011 |
