Title: X-ray machine, solid state radiation detector and method for reading radiation detection information
Inventor: PAI JOSEPH Y
IPC: H05G1/30
Filed: 1994-12-29
Abstract: A solid state radiation detector having an improved method of reading data from individual sensors and an x-ray machine configured with such a solid state radiation detector. At least one sensor of the solid state radiationdetector is designated as a reference sensor. The output of the reference sensor is read until it reaches a predetermined threshold. Once the threshold has been reached, a timer determines when the predetermined x-ray exposure time is completed. Upon completion, the sensors of the solid state radiation sensor are read. Thus, all sensors may be read at the proper time to achieve maximum output in spite of an unknown and variable warm-up period for the x-ray tube following activation and possibly an unknown exposure time. Alternatively, once the output of the reference has reached the predetermined threshold, the output of that reference continues to be monitored to determine when the output of the reference sensor falls below a second predetermined threshold. At approximately that time, all sensors of the solid state radiation detector are read.

Filed: 1995-01-12
Abstract: A railway vehicle truck bolster friction shoe pocket includes a sloped rear wall and longintudinally spaced sidewalls depending from the rear wall to form a friction shoe pocket having open top and bottom ends for receiving a variable rate type of friction shoe. During rotation and translation of the bolster with respect to the truck sideframe, the outboard friction shoe pocket sidewall is repeatedly impacted by the outer and upper corner of the friction shoe. The impacting causes protuberances to form in the outboard sidewall, but only on the upper portion of the wall. The same sidewall is provided with a relieved section across the entire sidewall upper portion in order to eliminate the impact contact area between the upper portion of the friction shoe and the upper portion of the outboard sidewall. Eliminating the contact area eliminates the formation of protuberances and extends the life of the bolster.

Title: Process for recovering olefins from cat-cracked gas without accumulating undesirable oxides of nitrogen
Inventor: GRENOBLE DANE CLARK
IPC: C10G70/04
Filed: 1993-10-28
Abstract: Recovering olefins from cat-cracked gases without the accumulation of dangerous amounts of nitrogen oxides is achievable in a safe, effective, and economical manner by conducting the recovery at temperatures that are high enough to prevent the oxidation of nitric oxide (NO) to form nitrogen dioxide (NO2) and high enough to prevent the accumulation of unwanted nitrogen oxides. One way to achieve this result is using well known absorber technology to operate the demethanizer rather than using the typical cryogenic technology.      A stream of cat-cracked gas (10) first is scrubbed to remove acid gases, including nitrogen dioxide (NO2), and then is gassed through a depropanizer fractionation tower (12). Hydrocarbons having four or more carbon atoms are recovered in the bottoms (16) of the depropanizer, and the overhead (14) from the depropanizer - which is composed of hydrocarbons having three or fewer carbon atoms - is sent to an absorber demethanizer tower (18). Hydrocarbons having two or more carbon atoms are recovered in the bottoms from the absorber demethanizer tower, where temperatures are no lower than about -46 ° C (-50 ° F). The overhead (20) from the absorber demethanizer tower - which is composed of methan, hydrogen and trace amounts of nitrogen oxide, C2, and absorbent (C3) - then is chilled to condense (24) and recover trace amounts of C2 and heavier gases, including trace amounts of the C3 absorbent (26), at temperatures of about -101 °C (-150 °  F) or higher.
