Abstract: The disclosure concerns a method and a control arrangement for controlling valve actuation of an ICE comprising an exhaust valve, an intake valve, and a turbo compressor. The method comprises and the control arrangement is configured to: limiting/limit valve actuation changes of the exhaust and intake valves based on compressor data including surge limit data for the turbo compressor and one or both of a current turbo compressor rotational speed and a current turbo compressor pressure ratio, to maintain a turbo compressor mass flow above a limit mass flow value.

Abstract: An insulating system (10) for protecting the exterior surfaces of steel pipes and pipe bends (100) from corrosive elements wherein, the insulating system (10) includes a primary coating (20) on the exterior surface of the steel pipe (100) a first inner layer of tape wrap (30) a pair of polyurethane half shells (40) (40′) surrounding the first layer of tape wrap (30) wherein, the exterior surfaces of the polyurethane half shells (40) (40′) are provided with a coating of mastic (50) that bonds with a second outer layer of tape wrap (60).

Abstract: A self-powered neutron flux detector having an emitter electrode, at least a major portion of which is, .sup.95 Mo encased in a tubular collector electrode and separated therefrom by dielectric material. The .sup.95 Mo emitter electrode has experimentally shown a 98% prompt response, is primarily sensitive to neutron flux, has adequate sensitivity and has low burn up. Preferably the emitter electrode is molybdenum which has been enriched 75% to 99% by weight with .sup.95 Mo.
