1. A process for the production of moulding compositions from saturated polyesters, which are reinforced with from 15 to 50% by weight, based on the moulding composition, of glass fibres, by incorporating the glass fibres into the polyester in an extruder, wherein from 6.66 to 30% of the amount of glass fibres used is fed into the extruder together with particulate polyester, and 93.34 to 70% of t...

A two axis rate and linear acceleration detecting multisensor is formed by mounting a pair of accelerometers of the constrained mass type within a case. The accelerometers are mounted orthogonal to each other in vibratory units responsive to an electromagnet therebetween. Rate is determined from the coriolis acceleration force experienced by the accelerometers which vibrate 180 degrees out of phas...
