摘要:
An inspection system for a conduit comprising measurement means for travelling in the conduit and obtaining data on the conduit, and processing means for processing the data to identify regions of the conduit corresponding to defects in the conduit. The measurement means may be laser scanning means and sonar scanning means.

Une remorque d'autoroute (12) pour traîner une cargaison possède des freins pneumatiques (14). Une soupape (28, 30) montée sur la remorque (12) et reliée à la conduite pneumatique (16, 18) maintient dans la conduite une pression pneumatique provoquant l'application des freins lorsque la remorque est garée. La soupape (28, 30) possède une poignée de verrouillage (42) empêchant le vol de la remorque.
摘要:
A single or multi-layer circuit board is formed by printing directly onto an electrically non-conductive medium using a metal-based fluid which, upon drying, leaves behind a solid metallic residue defining a predetermined circuit configuration. For multi-layer boards a plurality of conductive and non-conductive layers are printed alternately onto a non-conductive substrate or onto a conductive substrate pro- vided with a non-conductive surface.
摘要:
An intrinsic piezoelectric transformer circuit a piezoelectric transformer circuit is provided that has a primary side component including first and second electrodes, a secondary side component including first and second electrodes, and at least one tertiary component including first and second electrodes. A power bridge is provided which includes one or more switches, each switch has a gate terminal that is directly connected to the second electrode of the tertiary component of the piezoelectric transformer. The first electrode of the tertiary component of the piezoelectric transformer is connected to a reference for the one or more switches of the power bridge. The first electrode of the primary component of the piezoelectric transformer is electrically connected to a power bridge output and the second electrode of the primary component of the piezoelectric transformer is connected to a ground terminal.
摘要:
A method and apparatus of printing wherein, prior to printing, an ultra-violet (U.V.) varnish is applied to the whole of, or to one or more selected parts of, the paper to be printed and is hardened by passage past one or more U.V. lamps (19), printing then being carried out using one or more U.V. inks which are dried by passage past one or more further U.V. lamps (20), or using other ink or inks which can be acceptably dried.
