20100166582 | POLYMER MATERIAL AND SEALS FORMED THEREOF FOR HIGH PRESSURE PUMP APPLICATIONS - A seal is formed of a material including a crosslinked fluoropolymer. The seal substantially prevents leaks in a high pressure pump. | 07-01-2010 |
20100224400 | OVERLAP HELICAL CONDUCTIVE SPRING - A cross-diametric compression spring includes a conductive ribbon formed into an overlapping helical coil wherein adjacent loops of the conductive ribbon overlap. The conductive ribbon has a width extending substantially parallel to length of the overlapping helical coil. | 09-09-2010 |
20100240228 | LINEAR MOTION ELECTRICAL CONNECTOR ASSEMBLY - A linear motion electrical connector includes an outer component having a bore defined by an inner surface and a cylinder within the bore. The cylinder has an outer surface. An annular groove is formed on one of the outer surface of the cylinder or the inner surface of the outer component. The annular groove has an axial length. A conductive spring is fit within the annular groove and provides electrical contact between the outer component and the cylinder. The conductive helical spring is adapted to roll along the axial length of the annular groove to maintain electrical contact when the cylinder is translated relative to the outer component. | 09-23-2010 |
20110079962 | MODULAR POLYMERIC EMI/RFI SEAL - A seal includes a seal body including an annular cavity, and an annular spring within the annular cavity. The seal body, the seal body includes a composite material having a thermoplastic material and a filler. The composite material can have a Young's Modulus of at least about 0.5 GPa, a volume resistitivity of not greater than about 200 Ohm-cm, an elongation of at least about 20%, a surface resistitivity of not greater than about 10 | 04-07-2011 |
20110140369 | SYSTEM, METHOD AND APPARATUS FOR SPRING-ENERGIZED DYNAMIC SEALING ASSEMBLY - A seal assembly is disclosed. The seal comprises a metal spring bonded to an elastomer body that is coupled to a polymer ring. The spring may comprise a cantilevered, overlapped metal strip. The elastomer and polymer mechanically interlock with radial members. The elastomer has contacting surfaces configured in outward extending radii to enhance forward edge loading and oil removal from the dynamic surface. In hydraulic service, the seal prevents the egress of hydraulic fluid and ingress of foreign particles. | 06-16-2011 |
20110263164 | SYSTEM, METHOD AND APPARATUS FOR STRANDED CANTED COIL SPRING - A stranded canted coil spring for electrical contact between adjoining elements is disclosed. The spring is formed from a stranded wire having coils that define a toroid. | 10-27-2011 |
20120177906 | POLYMERS WITH METAL FILLER FOR EMI SHIELDING - A composite material includes a thermoplastic material, and a metallic filler dispersed within the thermoplastic material. The metallic filler may be fibrous, particulate or a combination thereof. The metallic filler may have a length in a range of about 3 mm to about 10 mm, and/or a mean particle size of about 2 microns to about 10 microns. The composite material may have a volumetric resistivity of not greater than about 0.5 Ohm·cm. The composite material can be in the form of a sealing component. | 07-12-2012 |
20130170980 | Polymer Material and Seals Formed Thereof for High Pressure Pump Applications - A seal is formed of a material including a crosslinked fluoropolymer. The seal substantially prevents leaks in a high pressure pump. | 07-04-2013 |
