Abstract: A vial transfer mechanism is provided for transferring radioactive samples from a sample changer to a radioactivity counting or measurement chamber via a bottom access conduit. Vials are lowered, either individually or as a group, from the sample changer into a sample-receiving carriage, which then moves along a horizontal conduit to a position underneath the measurement chamber. An elevator then lifts the sample from the carriage into the chamber. Light tightness is provided by equipping the carriage with O rings so that the chamber is not exposed to atmospheric illumination. The device is particularly useful for the simultaneous counting of two or more samples, where the samples are located in proximity to each other while in the sample changer, but must be spaced away from each other during radioactive measurement.

Abstract: A tiltable tray mechanism is provided having a fixed support member, a normally horizontally disposed tray arranged above the support member, a piston and cylinder assembly fixedly mounted to the support member and disposed beneath the tray, and a clevis and pin arrangement for connecting the piston to the tray so that the tray is tiltable with respect to the piston out of its normally horizontal position. The piston and cylinder assembly has its piston generally vertically disposed and extending toward the tray. A coil spring is interposed between the tray and the fixed support member for urging the tray into the normally horizontal position, and the piston is operable upon retraction into its cylinder to overcome the bias of the spring and tilt the tray. A stop carried by the fixed support member is laterally displaced from the vertically disposed piston, the stop being located beneath the tray for engagement by the tray in response to retraction of the piston into its cylinder so that such engagement causes the tray to be tilted with respect to the horixontal and against the bias of the spring. A guide pin is fixed to the underside of the tray and extends through an opening provided in the fixed support member for engagement with the sides of the opening to thereby limit the extent of tilting movement of the tray.
