Abstract: A one piece self-supporting collapsible plastic urology drain bag 24 is mounted to an examination end 14 of a urology table 10. The pan includes a vertical inner end wall 28, a sloping outer end wall 34, a pair of opposite side wall 30, 32, and a bottom wall 36 through which a drain port 38 is defined. The inner end wall 28 of the drain pan is secured between plates 50 and 52. The drain bag is sufficiently flexible to allow a physician to collapse the outer end wall 34 against inner end wall 28 yet with sufficient plastic memory to enable the drain pan to return to its non-flexed position when the collapsing force is removed. A retaining means 56 is disposed on each end of the upper edge of plate 52. Each retaining means comprises a support means 58 and pin 60 arrangement.

Abstract: An X-ray spotfilming apparatus including a film cassette carriage mounted for longitudinal, reciprocating motion in housing having at least one film cassette receiving opening. A carriage drive system including a servomotor and a feedback potentiometer is operative to drive the film carriage between a retracted position and a plurality of exposure positions. Clamp members are mounted for sliding transverse movement within the carriage assembly and are operative in connection with a clamp coupling mechanism and clamp drive system to effect both clamping and translational movements within the carriage. A cassette advance apparatus drives a film cassette to a predetermined position along a clamp members and includes a advance pawl engageable with the cassette and a feedback pot for monitoring the position of the pawl. The feedbck signals from the clamp drive and cassette advance potentiometers are utilized to determine the longitudinal and transverse dimensions of the film cassette.
