摘要： A resettable switching device, e.g. a relay, comprises a fixed contact (18) and a movable contact (28). A solenoid (12) is fixed relative to the fixed contact and a ferromagnetic plunger (20) carries the movable contact. A spring (24) biases the plunger away from the fixed contact so the device is normally open. When the device is set a further ferromagnetic element, e.g. a plunger (22), holds the first plunger (20) in a closed-contact position by magnetic attraction against the action of the spring (24). When a predetermined current condition exists in the solenoid the magnetic attraction between the element and plunger is reduced below the level necessary to hold the plunger so that the movable contact disengages the fixed contact.

摘要： An end of life quenching device for a vapor lamp preventing damage to the lamp and socket structure. Mica is attached to a lead wire of a filament. As an emission material on the filament is consumed and the vapor lamp reaches the end of its life, the resulting increase in voltage causes an arc. The arc may extend down the lead wire. The hydrated OH group in the mica releases hydrogen, which extinguishes the arc within the vapor lamp. Damage is thereby prevented. The mica withstands the high pressing temperatures required in the manufacture of vapor lamps with quartz envelopes and used to generate ultraviolet radiation in germicidal applications.

摘要： Paunch-sludge from an abattoir is mixed with the fatty DAF-float from an abattoir, and placed in a shearing vessel. The mixture of the two material thickens the medium in which the matted strands are contained, enabling shearing to be more effective; so much so that paunch-sludge can now be sheared to a homogeneous liquid. The technique can be used with other sludges and other fatty waste materials.

摘要： Hydrophobic contaminants are removed from sludge that has been liquidized by violent shearing, by stirring a hydrophobic sorbent substance material into the sludge. After a period of time in which the contaminants are sorbed into the sorbent, the sorbent substance is separated from the sludge by gravity-settling, centrifuging, etc, where the sorbent is a liquid, or by filtration etc where the sorbent is a solid. Some sorbents have a melting point such that the sorbent can be liquid for good dispersal in heated sludge, and then can be solid when the sludge has cooled, whereby the sorbent can be removed e.g by filtration. Liquefaction by violent shearing causes the biosolids in the sludge to go into solution, which leaves the hydrophobic contaminants more available to be sorbed.

摘要： An arc fault detector comprises a current transformer (CT) having a primary winding and a secondary winding (W1), the primary winding being formed by at least one conductor (L) of an AC or DC supply circuit. The inductance of the CT is selected so that the CT has a lower frequency operating point (LFOP) of at least 10 KHz. The detector also comprises circuitry (10, 12, SW) for disconnecting the supply if the voltage induced in the secondary winding meets predetermined criteria as to magnitude and duration.
