Patent number: 8245733Abstract: A clip (6) of molded plastics material for fitting on a pipe or duct in particular a blow-molded automotive fluid duct, comprises an open ring of generally C-shape having facing arms (20) that are curved and with open ends that can be sprung apart and together again to resiliently fit the clip on the pipe or duct. The facing arms (20) have profiled inner surfaces that engage with complementary profiles carried by the pipe or duct, namely the facing arms (20) have a substantially T-shaped profile (23/24), that fits between pairs of complementary spaced-apart arcuate ribs and recess carried by the pipe or duct. The clip (6) is easy to fit and remove while providing firm holding power and good pull-out strength.Type: GrantFiled: November 10, 2010Date of Patent: August 21, 2012Assignee: E I du Pont de Nemours and CompanyInventor: Michel C. Renaud

Patent number: 7989548Abstract: The invention relates to a new polymer blend comprising: 20 to 70 wt % of a mixture (A) of two or more polyalkylene phthalates; 2 to 60 wt % of a cross-linked acrylate rubber; 0.5 to 20 wt % of an ionomer; and 1 to 30 wt % of a terpolymer of ethylene, butylacrylate (BA) and glycidylmethacrylate (GMA); wherein the weight percentages are based on the sum of the above ingredients. The polymer blend of the invention is particularly suitable for blow-moulding, to make parts for high-temperature, high-oil-exposure uses.Type: GrantFiled: July 7, 2009Date of Patent: August 2, 2011Assignee: E.I. du Pont de Nemours and CompanyInventors: Vincent Descombes, Philippe Leboeuf, Jean-Michel Philippoz, Michel C.

Patent number: 7017780Abstract: A dispenser for storing and dispensing small items is provided. The dispenser includes a base container having an a hollow space for storing items to be dispensed, a cover sized to fit over the opening of the base container, and a wheel rotationally mounted under the cover which has a shaft and at least three fins radially extending from the shaft and spaced from each other around the shaft. The wheel is mounted under the cover such that the fins of the wheel can rotate under the cover and carry an item stored within the base container to a port in the cover. The rotating fins on the wheel are aligned so as to contact and pass over the raised boss on an inside surface of the cover each time the wheel is rotated 360 degrees. An actuator is also provided for manually rotating the wheel under the cover, which actuator is accessible from outside of the dispenser. Both the cover and the fins of the wheel are made of plastic.Type: GrantFiled: November 14, 2003Date of Patent: March 28, 2006Assignee: E. I. du Pont de Nemours and CompanyInventor: Michel C. Renaud
