Title: Silent damper with anti-rattle shaft
Inventor: WACH JOE
IPC: F16F9/32
Filed: 1999-08-26
Granted: 2004-03-30
Abstract: The damper includes a housing assembly and a piston assembly with reciprocates within the cylindrical walls of the housing assembly. The piston assembly is formed from two disks which are spaced apart by a spacer with includes radially and longitudinally oriented planar projections which extend to a position radially inward of a periphery of the disks. The distal ends of the projections form longitudinally oriented surfaces upon which a toroidal seal slidably rides. At least one of the longitudinally oriented surfaces includes an air communication groove in communication with a groove on the trailing disk which extends to the periphery of the trailing disk. When the piston assembly is retracted from the housing assembly, the seal engages the leading disk thereby inhibiting air from flowing through the air communication groove thereby effectuating damping. However, when the piston assembly is inserted into the housing assembly, the seal engages the trailing disk thereby allowing air to flow through the air communication groove thereby eliminating or minimizing damping.      The- cap of the housing is formed by portions of elastic O-rings which extend across the mouth of the housing slidably retaining the piston shaft.

Title: Impact resistant composite shell for gas turbine engine fan case
Inventor: ROBERTS PAUL D D
IPC: F01D21/04
Filed: 1999-05-20
Granted: 2007-12-11
Abstract: The invention relates to an impact resistant fibre composite shell for supporting an elastic containment belt after impact with a radially propelled broken fan blade of a gas turbine engine. A conventional gas turbine engine can include a fan with a hub and fan blades disposed for rotation about a central axis. A life threatening and extremely damaging condition can result in flight if a defective fan blade breaks away from the hub and is propelled radially al high velocity under centrifugal force. Conventionally a cylindrical fan case is provided about the periphery of the fan to compliantly contain a broken fan blade propelled radially outward from the rotating hub. Typically, the fan case includes an elastic blade containment belt of several Kevlar fabric plies for example, and a belt support shell disposed inside the belt, usually fabricated from aluminium. The invention provides an impact resistant fibre composite support shell of improved design. The fibre composite shell has two end support hoops each integrally manufactured with and structurally bonded to, centre breakaway lattice disposed radially adjacent the fan blades. The lattice permits the broken blade to cut a slit through the breakaway lattice passing to the elastic blade containment belt. The slit lattice has sufficient residual post-impact strength to distribute post-impact loads imposed by the elastic blade containment belt to the end support hoops of the shell.

Title: Apparatus for detecting raman gain in an optical transmission system
Inventor: DENKIN NATHAN MYRON
IPC: H04B10/29
Filed: 2001-04-23
Granted: 2005-09-06
Abstract: A unique sensor is used to detect a transmission impairment that may have affected incoming optical channel signals. The sensor, more specifically, selects a group of the incoming channel signals and generates a first power signal, P0, over the selected group of signals and generates a second power signals, P1, over a weighted version of the selected group of channel signals. The sensor then generates, as a function of the first and second power signals, P0 and P1, a signal indicative of whether the particular transmission impairment affected the levels of individual ones of the incoming channel signals. If so, then control apparatus offsets the impairment accordingly.

Abstract: A grader vehicle has a vehicle body mounted on two drive tracks. A boom is mounted on the front of the vehicle and extends to the front of the body. A third drive track is mounted on the leading end of the boom by a steering mechanism for rotation about an upright steering axis. The three tracks are driven by separate hydraulic motors. The use of a steering, driven track on the boom provides a tractive force pulling the vehicle forwards in the desired direction of travel and positively driving the leading end of the boom in the direction of a turn. The track also provides a degree of packing at the centre of the vehicle's path that can not be achieved with a ski gliding on the surface. This is of particular importance when packing ski trails with the vehicle. For grading purposes, the vehicle has a grader blade across the front of the vehicle and a second blade leading the front track. This provides both grading and packing at the centre of the track where prior art tracked vehicles would at most provide a grading action with a scraper blade.

Abstract: A method for inspecting the material distribution of a sequence of stretch blow molded containers or other articles in a continuous production process, by providing injection molded parisons, each parison having at least one indicator, typically two or more indicators, for detecting material distribution at a predetermined position along the axial extent of the parison. Each of the parisons is subjected to a heating stage in the continuous production process, generally by exposure to infrared heating. Each heated parison is then subjected to a blow molding process, which can be a stretch blow molding process, so that each material distribution indicator is transformed to a corresponding position along the axial extent of the blow molded article. A detector is positioned to detect the location of each indicator on each blow molded article from a given mold in the production process. A computation is then made to determine for each blow molded article a material distribution outcome or profile based on the detected locations of each indicator. This information on material distribution is them matched to a prescribed profile for the particular container design and any discrepancy beyond some preset tolerance value is employed to reject the out of tolerance item from the production line, and to modify a step of the manufacturing process such as the infrared heating pattern.
