Abstract: Heat is removed from, or supplied to, a vertical pipe of any cross-section, whose internal temperature is above or below the ambient temperature and whose wall temperature must neither exceed nor fall below a predetermined temperature range, by a method in which, in order to maintain the predetermined temperature range, the pipe is provided with a coaxial sheath and gas is passed through the gap between the pipe and the sheath. The invention is particularly directed to maintaining a predetermined temperature range at the outer pipe wall of the vertically oriented, double walled pipes which connect the reaction sections with the collectors in a steam reformer.

Abstract: The seal for the spindle (1) of a fitment, such as a valve, consists of a stuffing box (2) and a ductile, elastic sealing-ring (10). The sealing ring is pressed round the spindle by an adjustment (11) in a groove (8) on the inner periphery of a holder-ring (5) surrounding the spindle. The adjustment consists of an adjusting ring (12) placed in a thread (13) on the inner periphery of the holder-ring against the hollow sealing-ring. USE/ADVANTAGE - The seal is for any size of fitment-spindle.

Abstract: The monitoring system for ignitable gases and vapours, etc., contains pipe branches at defined intervals leading up to the monitored system. The pipe branches are connected via a collection system to detectors for the gases, vapours, etc. The openings of the pipe branches are protected against ingress of precipitation and/or fouling by covers. The system can be installed above or below ground. USE/ADVANTAGE - Large area detection system enables reliable, continuous and efficient monitoring e.g. in oil processing plant.
