Patent number: 7566374Abstract: A method of making a mat with a textile surface and an elastomer backing is provided. The method includes mixing elastomer crumbs and a binder, depositing the crumb/binder mixture in a layer (22), placing a textile surface element (34) on the layer to form a mat assembly, and pressing the mat assembly in a press (9) while setting the binder. The elastomer crumbs are consolidated to form an elastomer backing (2) that includes voids between the elastomer crumbs, and the textile surface element is bonded to the elastomer backing to form the upper textile layer (1) of the mat.Type: GrantFiled: June 12, 2003Date of Patent: July 28, 2009Assignee: Milliken & CompanyInventors: Peter C.

Publication number: 20080063515Abstract: The bypass turbomachine comprises, between a primary flowpath (2) and a secondary flowpath (3), a structural intermediate casing (14). A bleed passage (29) allows the diversion of a portion of the gas stream toward the secondary flowpath (3), downstream of support arms (18) situated at the periphery of the intermediate casing. A bleed opening (28) emerges upstream of the support arms (18). A slide valve (22) slides between three positions, namely a closed position in which the slide valve (22) completely blocks off the bleed passage and opening, an intermediate position in which the bleed opening (28) emerging upstream of the support arms (18) is blocked off, while the bleed passage (29) for diverting a portion of the gas stream downstream of the support arms (18) is open, and an open position in which the bleed opening (28) emerging upstream of the support arms (18) and the bleed passage (29) emerging downstream of the support arms are both open.Type: ApplicationFiled: May 31, 2007Publication date: March 13, 2008Applicant: SNECMAInventors: Eric BIL, Gilles Charier, Philippe Fessou, Patrick Morel

Patent number: 6799416Abstract: The invention provides a device for supporting and recentering a shaft (2) after decoupling. The device comprises an annular support (4) surrounding the shaft (2), a bearing (5) secured to the annular support (4) and having an inner ring (9) which is spaced apart from the shaft by clearance J. The inner ring (9) has two webs or tenons (14a, 14b) that are normally held to the periphery of two troughs (16a, 16b) carried by the shaft (2). Two sets of balls (28a, 28b) normally bear against the bottoms of indentations (25, 26) formed facing one another in the adjacent radial walls of the troughs (16a, 16b) and of the inner ring (9). Resilient means (26) tend to urge the troughs (16a and 16b) towards each other. In the event of the webs or tenons (14a, 14b) breaking due to a large unbalance, the balls (28a, 28b) roll on the walls of the indentations (25, 26) and move the troughs (16a, 16b) apart from each other.Type: GrantFiled: March 14, 2003Date of Patent: October 5, 2004Assignee: SNECMA MoteursInventors: Daniel Plona, Patrick Morel

Patent number: 6451400Abstract: There is provided a mat having multiple sets of pins, each set of pins being located within surrounding, characterized in that the pins do not extend significantly beyond the highest point of the surrounding. Thus the pins are protected by the surrounding and are less likely to break after extended use. The mat may be provided with areas adapted for the receipt of strips of textile materials, eg carpeting which advantageously has a hard-backing and is able to snap into the areas provided. The inclusion of the textile material combines a scraping function together with the visual appearance of a carpet. The strips of textile material will be separated by sets of pins as described above. A set of such mats is also described.Type: GrantFiled: March 10, 2000Date of Patent: September 17, 2002Assignee: Milliken Denmark A/SInventors: Thomas A. P. Brock, Keijo J. Nurmentaus, Patrick Morel
