Abstract: A turbocharged engine system with electric compressor arranged to inject a compressed fluid into the exhaust subsystem upstream of the turbine of the turbocharger such that, in use, the compressed fluid injected by the electric compressor into the exhaust subsystem maintains the speed of or accelerates the turbine, thereby maintaining or increasing the boost pressure supplied to the turbocharged internal combustion engine. A method of controlling the boost pressure supplied to an internal combustion engine by a turbocharger, said method comprising the steps of: producing a stream of compressed fluid; injecting the stream of compressed fluid into an exhaust stream of the internal combustion engine to produce a pressure-boosted exhaust stream; and controlling the speed of a turbine of the turbocharger using the pressure-boosted exhaust stream to control the boost pressure supplied to the internal combustion engine.

Abstract: A container for the temporary storage of fluids and in particular liquids. The container comprises a flexible outer sack (211) enclosing a flexible inner fluid bladder (210) having an inlet port (215) and an outlet port (216) so that fluid may toe introduced and drained from the inner bladder. The inner bladder is configured with a plurality of folded regions such that when a fluid is introduced into its interior the inner bladder unfolds within the outer sack in such a way that reduces the risk of pinching of the inner bladder resulting in uneven filling and tearing of the bladder. The fluid container is suitable for use with conventional crate and pallet systems for the transport of liquids and semi-liquids.

Abstract: A device for detecting objects behind a wall or like surface has a multiplicity of capacitor plates at spaced intervals and a circuit for sensing alterations in the dielectric constant of a region of the surface being inspected and adjacent to each of the capacitor plates. A multiplicity of quantitative display elements are arranged at intervals in a visual display, and each display element provides a quantitative value representative of the strength of the signal generated by the associated capacitor plate. Thus, the images in the display elements will increase and decrease to reflect the quantitative signals and effectively image the object being detected.

Abstract: A device for detecting concealed objects behind a surface, the device being intended in use to be held near and passed over the surface. The device detects changes in the dielectric constant of the surface resulting from the presence of concealed objects, and also includes metal detector means. The design precludes interference between the two kinds of sensors.
