  • Patent number: 5092161
    Abstract: A technique for detecting faults, blockages or holes, in a duct (6). A burst of compressed gas is injected into the duct and the decay of the pressure pulse monitored by a transducer at the gas burst launch end of the duct. A reference decay pressure that would be expected for a perfect duct is generated and the monitored decay is compared with the reference decay for deviation. A perforated duct exhibits greater pressure decay and a blocked duct less pressure decay than a perfect duct. The time occurrence of the deviation indicates the location of the fault. The signal level indicative of the pressure after a predetermined interval may also be used to measure the air friction or blowability within the duct.

  • Patent number: 4682834
    Abstract: A multiple contact connector has an elongate actuating member which is reciprocally mounted in a housing holding the contacts, the contacts in one or more linear arrays. On longitudinal reciprocation of the actuating membert it is also caused to reciprocate up and down in a direction normal to the longitudinal direction. In so doing it pushes on the contacts, deflecting them sideways. The connector is then assembled or inserted, after which the actuating member is moved to release the contacts. A substantially zero insertion force is obtained.
