20090126194 | NOISE ATTENUATORS AND METHODS OF MANUFACTURING NOISE ATTENUATORS AND BLEED VALVE ASSEMBLIES - Methods of manufacturing a noise attenuator are provided. In an embodiment, by way of example only, the method includes shaping a plate to have a three-dimensional contour, and forming a plurality of openings through the shaped plate with an abrasive fluid jet to thereby form the bleed valve noise attenuator. In another embodiment, a bleed valve assembly is provided. By way of example only, the assembly includes a plate having a three-dimensional contour including a rim section surrounding a dome section and a plurality of openings formed in at least one of the rim section and the dome section, the plate comprising a material having no recast material thereon. | 05-21-2009 |
20120117807 | ULTRASONIC PIERCING NEEDLE - A puncture needle capable of clear imaging even if an angle to the irradiation direction of a detection wave is small. According to one embodiment, a ultrasonic puncture needle that conducts puncturing while observing a puncturing condition by means of a ultrasonic image is formed with an edge at the tip end of a puncture needle body, and formed at a specified position of the puncture needle body with at least one corner cube mirror formed by a triangular pyramid recess. Since a ultrasonic wave oscillated from the ultrasonic probe is reflected off the corner cube mirror to be returned to the ultrasonic probe, the reflected wave progresses in the same direction as the incident direction of the ultrasonic wave to be positively returned to the probe even when an angle formed by the irradiation route of a ultrasonic wave and the axis of the puncture needle is small. | 05-17-2012 |
20130180111 | FIXING JIG, FIXING METHOD, AND HONEYCOMB FILTER PRODUCTION METHOD - A fixing jig includes a pedestal including a placing surface on which a columnar honeycomb structure is placed, holding members fixed to the pedestal and configured to hold a side surface of the honeycomb structure placed on the placing surface, and drawing and fixing members fixed to the pedestal and configured to draw and fix the surface on the pedestal side in the outer circumferential portion of a mask placed on the honeycomb structure. Consequently, the fixing jig can fix the honeycomb structure and the mask aligned with each other and is less likely to hinder the alignment of the mask. | 07-18-2013 |
20140123494 | MANUFACTURE OF A FILTER SCREEN - A method of manufacturing a filtering screen includes: attaching handle members ( | 05-08-2014 |
20150143699 | STAMPED WHEEL BALANCING WEIGHT - A wheel-balancing weight mounts to a wheel with a flange. The weight includes a body and a clip. The body is stamped by a punch to define a pocket within which an attaching portion of the clip resides. The defined pocket has a planar base and opposing side walls generally perpendicular to the base. The body as stamped by the punch includes a pre-stake for each side wall external to the pocket and adjacent the side wall, and an undercut for each side wall within the pocket and generally located at a juncture of the side wall and the base. | 05-28-2015 |

20100287775 | METHOD AND DEVICE FOR PRODUCING HELICAL SCREENS - A method and a device for producing helical screens by winding wires made of plastic into individual spirals, which are inserted into each other in an overlapping way in the transversal direction on a working surface and are united parallel to each other into permeable sheet materials by fixing wires. In order to achieve the task to provide a method and a device with which screen belts with spirals and fixing wires can be produced with low personnel, energy and investments costs (equipment costs) and low amounts of waste with high precision and reproducibility with low time effort, the invention proposes for the spirals to be deposited on winding devices by means of moveable joining devices next to each other on the work surface after winding and to be engaged on said work surface by transverse displacements and connected to each other by the fixing wires. | 11-18-2010 |
20130185940 | MANUFACTURING OF SAND SCREENS - A rod-based well screen is formed in place on a perforated pipe base by wrapping wire around the pipe base and a plurality of rods located around the outside of the pipe. The wire is welded sequentially to each individual rod as it is wrapped around the pipe. The welding and ground electrodes engage the wire and the rods respectively. The rod engaging ground electrode is positioned a short distance ahead of the wire being wrapped around the rods and the pipe base. The ground electrode includes a plurality of contacts. Each contact is mounted to pivot toward and away from a rod. Springs urge each contact toward a rod to hold the rod against the outside surface of the pipe base and to maintain good electrical contact between the contact and the rod. Each contact has a groove to guide the rod into position for welding to the wire. | 07-25-2013 |
20150375144 | METHOD OF ASSEMBLY FOR SAND SCREEN - A method of assembling a sand screen assembly includes the steps of providing inner and outer shrouds having radial protrusions, such as ribs, louvers, splines, etc., that are radially unaligned during a first assembly step thereby providing clearance for positioning of a filter layer between the shrouds. The outer or inner shroud is then rotated until the protrusions are aligned and the clearance between the shrouds and filter layer is eliminated to provide a tight fit between the layers. | 12-31-2015 |

20090293279 | METHOD OF MAKING ELECTRET ARTICLES BASED ON ZETA POTENTIAL - A method of making an electret article, from a polymeric article that has a zeta potential of greater than or less than −7.5 millivolts. The article is charged by contacting it with an aqueous liquid that has a pH and conductivity as follows: (i) if the article has a zeta potential of −7.5 mV or less, then the contacting liquid has pH greater than 7 and a conductivity of 5 to 9,000 microSiemens per centimeter; and (ii) if the article has a zeta potential of greater than −7.5 mV, then the contacting liquid has a pH of 7 or less and a conductivity of 5 to 5,500 microSiemens per centimeter. An electret article made in this manner can provide improved electret performance, particularly in electret filtration articles. | 12-03-2009 |
20100058589 | Structured material web having a multi-dimensional structure, and method for the production thereof - The invention relates to a structured material web, particularly a metal web, having a multi-dimensional structure comprising beads or creases and structures disposed next to each other and each formed by a surface section enclosed by the beads or the creases, wherein each of the structures has a dedicated location with a hole, and the surface section in every other location of the structure is formed by an incline toward the dedicated location. | 03-11-2010 |
