Title: System for producing discrete components or articles from continous fibre metal matrix composite
Inventor: SAWALHA KAMEEL DIAB
IPC: B22D19/14
Filed: 1994-08-10
Abstract: A system is proposed for the production of continuous fibre metal matrix composite components or articles by a liquid-metal (or liquid alloy) route in which pressure-waves and/or shock-fronts are caused to exist within the die in order to improve the infiltration of the molten metal around the fibre mat. The pressure waves inside the molten metal have very high pressure-gradients in the material and these short-term pressure gradients help the metal front to advance through the fibre. There are several possible mechanisms by which the desired pressure waves and/or shock-fronts can be produced but the most failsafe of these is to apply sharp shock-waves to the molten metal by impacting the sides of the die (Fig 1) or by using an appropriately designed wave-guide to conduct shocks directly into the metal within the die (Fig 2). Sensors can be used to detect when a good level of infiltration has been achieved. The system is applicable to components and articles of any geometry and any level or reinforcement. <IMAGE>

Title: Traffic calming device obstructs vehicle depending on its speed
Inventor: LEWIS GARY MARK
IPC: E01F9/529
Filed: 1997-04-11
Abstract: A traffic calming device 200 is disclosed which comprises a housing 13,15 a projection means adapted to move from a retracted position to a projecting position, and an actuation means 18 mechanically connected to the projection means. When a vehicle crosses the traffic calming device, it provides energy to the actuating means 18 which causes the projection means to move to the projecting position. The height of the projection means is dependent on the speed of the passing vehicle, and so slow vehicles can pass relatively unimpeded as the projecting means does not rise too high. Faster vehicles cause the projecting means to rise higher as to impede passage of the vehicle. Preferably the front wheels of the vehicle strike the actuating means 18 and the rear wheels of the vehicle then strike the projecting means. One or more such devices can be fitted across a lane of a highway. The device can be locked in the retracted position on receiving an electronic signal, from for example an emergency vehicle. There are several different embodiments of the device disclosed.
