Abstract: The aft stiffening frame (20) of an air intake structure (4) for an aircraft engine nacelle (2) is made with an inflection area such that the part between the inflection area (28) and one of its ends could be subjected to a large deformation when a constraint occurs in the direction of the frame part defined by the inflection area (28) and its other end (20e), usually normal to the casing (16). This particular shape of the aft stiffening frame (20) makes it possible to improve its flexibility so that the air intake structure (4) has better resistance to severe deformed shapes that could occur, for example, when a fan breaks on a wide body aircraft.

Title: Insect chymotrypsin and inhibitors thereof
Inventor: DUNSE KERRY MICHELLE
IPC: A01N63/50
Filed: 2004-04-23
Granted: 2010-01-26
Abstract: The present invention relates generally to a novel chymotrypsin that exhibits resistance to a plant serine proteinase inhibitor. More particularly, the present invention provides a chymotrypsin which is up-regulated in the gut of Helicoverpa armigera and Helicoverpa punctigera insect larvae when fed the serine proteinase inhibitors of Nicotiana alata. The novel chymotrypsin represents, therefore, a target for the identification of antagonists including inhibitors which are proposed to be useful in the control of Helicoverpa spp. populations that have become resistant to serine proteinase inhibitors produced in plants. The antagonists of the chymotrypsin may be topically applied to the plants or, when in proteinaceous form, may be produced by genetic means in plant cells. The antagonists may act at the level of gene expression or protein activity.

Granted: 2012-12-04
Abstract: In a reciprocating (RS) injection unit environment, as shown in Figure 1, a controller of the injection unit is arranged to continuously rotate the screw during both conventional plasticizing operation and shot injection. In this way the RS  unit is more efficient, utilizing less energy and producing greater resin output. The injection unit includes a non-return valve adjacent a nozzle, which non-return valve is either configured to rotate with the screw to reduce wear or presented as a ball check style noon-return valve. In an injection molding environment, the rotating screw includes flights that allow granules of resin to melt and mix in spaces between adjacent flights, but the flights are arranged substantially to inhibit excessive displacement of resin around the flights.

Abstract: A blood collection device comprises an open ended syringe like housing (10) into which a vacutainer can be inserted. The front of the device contains a needle holder (11) and a double ended needle (12). The needle holder can be decoupled from the housing and retracted into the device but only after the vacutainer (13) has been removed and a separate needle retraction device (28) has been inserted into the open end of the housing and pushed against the inner end of the needle holder. The needle retraction device comprises a hollow body which is under vacuum and which has an open end closed by a piston (5). The piston functions to decouple the needle holder from the blood collection device and lock the needle holder and at the same time to be decoupled from the hollow body. The piston containing the needle holder and the attached contaminated needle is sucked back into the hollow body to render the needle safe.
