Title: Gas blast interrupters
IPC: H01H33/70
Filed: 1980-08-15
Abstract: In a contacts closed position of the interrupter, one contact 3 engages a further contact 5 and passes substantially sealingly through an insulating orifice 11 in a tubular housing 10 which surrounds the electrode 5 and through a further insulating orifice 13 in a tubular guide 12 which surrounds the housing 10. Upon initial contact separation, formations 6 and 7 on the contact 5 progressively disengage from the contact 3 to draw an arc therebetween, and pressurised gas is supplied to an annular chamber 14 defined between the housing 10 and the guide 12. Upon further contact opening the contact 3 passes out of the orifice 11 and allows the pressurised gas to flow therethrough out of the chamber 14 along the arc to cool and de-ionise the latter. Upon still further opening the contact 3 also passes out of the orifice 13, thereby permitting the pressurised gas to flow therethrough out of the chamber 14 in the opposite direction to the flow of gas through orifice 11. <IMAGE>

Title: Planar transducer for metal loss measurement
Inventor: QUAYLE JOSHUA CREER
IPC: G01N17/00
Filed: 1981-11-09
Abstract: A transducer for the measurement of material removed by corrosion or erosion from equipment (eg. plant, pipelines and vessels). The transducer comprises two electrically conducting elements 1,4 in close thermal contact formed from strips wound or bent into a compact form (eg a planar helix). The narrow face of one element (1) is exposed to the agressive environment, the other face and all surfaces of the second element are protected by encapsulation or otherwise. Measurement of the electrical resistances of the element allows calculation of the loss of material from the exposed element. The planar transducer can be constructed and position with its exposed element sensibly contiguous and co-planar with the surface of the equipment of interest. Furthermore the element can be constructed from material closely resembling that of the equipment. The corrosion/ erosion rate on the element is thus representative of that sustained by the equipment. <IMAGE>
