Abstract: A security method for a computer, comprising: providing a security device having a communication connection to the computer and a separate communication connection to an external device; and, at the security device: receiving a message having the computer as the intended destination from the external device; verifying the message; and if the message is verified as legitimate, sending a corresponding message to the computer; or if the message is not verified as legitimate, not sending a corresponding message to the computer

Abstract: Apparatuses, devices, systems and methods for resin transfer moulding of composite articles are disclosed. A mould enclosure enclosing a fibre pack is provided and one or more resin ports are provided along a resin flow path within the fibre pack. Resin ingress into the fibre pack is controlled via valves or a flow control mechanism, each being operable to impose a flow rate on resin passing into the fibre pack.

Abstract: Apparatuses, devices, systems 1 and methods for resin transfer moulding of composite articles are disclosed. A mould enclosure enclosing a fibre pack (9) is provided and one or more resin ports (6a-6e) are provided along a resin flow path within the fibre pack (9). Resin ingress into the fibre pack (9) is controlled via valves (44a-44e) or a flow control mechanism (30), each being operable to impose a flow rate on resin passing into the fibre pack (9).

Abstract: Apparatus for separating grit from a grit-loaded liquid matrix while retaining organic solids in suspension, including an inlet for admitting liquid matrix into the apparatus, an outlet for removing grit-lite liquid matrix from the apparatus main chamber, and a vortex system for removing separated liquid matrix grit from the apparatus. The grit settling main chamber defines upper and lower subchambers communicating with each other through a central aperture. A fluid flow speed gradient is established between the apparatus fluid inlet and outlet. An Eddy type fluid dynamic component is added, providing combined enhanced coarse grit and fine organics discrimination and separation. The Eddy fluid dynamic component may consist of a trio of stationary fresh water supply force fed eductors.
