Abstract: A system for indicating cracks in a hollow aircraft blade, such as a helicopter blade. A system wherein a pressure differential is maintained within the blade with respect to the ambient atmosphere and including a pressure sensor for mounting on the blade in communication with the interior of the blade and having a member which moves in response to pressure changes within the blade, a beta radiation source mounted on the member and disposed for radiation transmission to a detector, a beta radiation detector for mounting on a nonrotating portion of the aircraft for receiving radiation from the source, and circuitry having the output of the detector as an input and providing an output which varies as a function of the position of the pressure sensor member for indicating the pressure condition within the blade. An improved beta radiation detector housing which sub­stantially eliminates detector sensitivity to radar transmissions while maintaining sensitivity to nuclear radiation in the beta range.

Abstract: An electrophotographic printing machine in which an electrostatic latent image recorded on a photoconductive member (10) is developed with a liquid developer material having a liquid carrier with pigmented particles dispersed therein. The developed image is transferred from the photoconductive member to a sheet of support material. Heat and pressure are applied by rollers (46, 44) to the developed image on the sheet of support material to vaporize substantially all of the liquid carrier transferred to the sheet and to substantially permanently fuse pigmented particles to the sheet of support material in image configuration without smearing. Fusing may thus be effected at a lower energy input with better image density and uniformity.

IPC: G06F11/34
Filed: 1987-08-11
Abstract: A memory pointer circuit includes a plurality of counters and a programmable logic array for controlling the counters to generate addresses for an acquisition memory. The programmable logic array directs a lower counter to generate a repeating sequence of addresses to store data before an event occurs, each pass through the sequence causing previously written data to be overwritten until an event has occurred and is stored in memory. The programmable logic array then directs the upper counters to increment and the lower counter to generate a following sequence of addresses to store data after the event occurs. Once the following sequence is complete, the upper counters are again incremented and the repeating sequence of addresses is again generated. The procedure is repeated to store multiple clusters of data and events in the acquisition memory. Once the acquisition memory is full, the stored data and events can be saved or overwritten.

Abstract: Electrical switchgear for fitment to installation circuit breakers.   Known switchgears have one or more contact points on which a switch mechanism acts, the switch mechanism interacting with an adjacent circuit breaker. Differential operation of the contact points is thus not possible. To operate the switch poles 35, 45, a switch mechanism 36, 46 is provided in each case, which switch mechanisms are independent of one another and in each case have a coupling element which engages with the adjacent circuit breaker. In this case, each switch mechanism 36, 46 operates a switch pole 35, 45 which in each case is designed as a two-way switch. The arrangement permits the optional connection of the switch poles as opening or closing contacts and allows them to be operated differentially.
