Abstract: A superplastic forming apparatus and method for forming a sheet of material at an elevated temperatures into a workpiece having a complex geometry. The process takes advantage of a mechanical forming step, which draws material along a major axis to form a first preform. Upon completion of the first mechanical forming step, a second, initial superplastic forming step acts on the first preform to create a second preform having a plurality of channels or grooves located thereon. The grooves or channels function to draw additional material prior to the second or final gas forming step, which completes the forming process by driving the material against a forming surface. Accordingly, the method and apparatus function to reduce forming time and eliminate thinning and wrinkling of the sheet material during the forming process.

Abstract: A method and apparatus for detecting degradation in the cam profile switching system in either bank 2, 3 of a V-engine 1 relies on a comparison of the lambda values in each exhaust bank 4, 5 immediately prior to and subsequent to a cam profile switching event in one of the banks. If there is little or no change after switching, then the apparatus deduces that the switched bank has experienced degradation. The method is easy to calibrate and does not require continuous monitoring of engine behavior.

Abstract: A vehicle has a vehicle body and a vehicle bonnet assembly. The vehicle bonnet assembly includes a bonnet 14 hinged at its front to the vehicle body 10 and latched at its rear by two latch devices. Each latch device comprises a latch assembly 17 mounted to the vehicle body 10 and a striker 21 mounted to the bonnet 14.

Each latch assembly 17 includes a latch claw 26 moveable between a latch position in which the striker 21 is held by the latch claw 26 and a release position in which the striker 21 is releasable from the latch claw 26. Each latch assembly 17 also includes a release member 27 which is operable by a driver of the vehicle to allow the latch claw 26 to be moved towards its release position and allow the bonnet 14 to be lifted.

Abstract: A expansion tank for an engine cooling system comprises a housing forming a main chamber and a swirl chamber, the swirl chamber being defined by a cylindrical wall. An inlet connection discharges through an inlet orifice towards a collector duct having an entrance. From the inlet orifice the coolant is directed as a stream or jet along the adjacent surface of the cylindrical wall towards the entrance of the collector duct, guided by circumferential ribs. The kinetic energy of the stream is converted into pressure energy so that the pressure delivered from the outlet connection is slightly above the pressure at the top of the swirl chamber, above the level of liquid. This swirl chamber pressure is set by the relief pressure allowed by a filler cap, the gain in pressure helping to avoid cavitation in a coolant circulation pump.

A temperature responsive actuator may be disposed to move the first and second valve members within the housing in accordance with the sensed temperature. A first bias may be configured to bias the first valve member toward preventing flow from the hot inlet to the outlet, and a second bias may be configured to bias the second valve member toward preventing flow from the cold inlet to the outlet.
