The rotor R can be rotatably mounted in a support and at least one permanent magnet (21 or 22), which is a temporary or permanent magnet, is arranged adjacent the rotor R rotatably mounted in the support. A rotating means (8), for example an electric motor, in use, rotates the rotor R. The torque applied to the rotor R is monitored to detect any electrical fault in the winding of the rotor R which...

A motion and intrusion detecting system wherein scanning at two different rates is carried out in order to more reliably detect fast and slow motion in a scene being viewed. Also, increased noise immunity is provided by providing a special scan which generates signals inhibiting generation of alarm indications corresponding to points at which a possible noise situation exists.

Deep aeration of sewage is carried out by pumping sewage from the vicinity of the surface of the tank to groups of nozzles (3) where it is mixed with air and then is ejected in the vicinity of the bottom of the tank. The passing of the sewage from the nozzles (3) draws in the air to be mixed therewith before ejection of the mixture from a collector (4) containing the groups of nozzles.

Improvements in the manufacture of transversely annular or helical corrugated thermoplastic tubing made by extruding a thermoplastic tubing and feeding the tubing into the jaws of revolving or recycling mold halves which come together about the tubing to form transverse corrugations therein, which improvement resides in bringing the mold halves about their recycle tracks or paths, particularly abo...
