Harnesses integrated with crashpads
Rigid foam crashpads are fitted in areas that pose the greatest danger in accidents – for example, side impact protection in doors, direct impact areas for the head, in the A-pillar or headliner and front impact areas of the passenger compartment. Polyurethane foam is also used in cable sets to protect the enclosed cables and to make it easier to fit the cable harnesses. |

Rolling piston pumps fluids
A novel compressor-expander, designed to make refrigeration systems more efficient, is efficient, simple and lubricated by the working fluid, writes Tom Shelley. It also appears to be a design that could be manufactured at low cost.
Apart from its obvious interest to the developers of air-conditioning systems for the automotive industry, it also appears to have potential as a pump for, say, hydraulic fluids, oil, or engine coolant systems.
