Patent CA-2187002-A1 (CA)
Inventor: THURSTON MARLIN O
IPC: G01T1/161
Filed: 1996-10-02
Abstract: System and apparatus particularly suited for tracking a radiopharmaceutical present within a lymph duct and locating a sentinel node within which the radiopharmaceutical has concentrated. A smaller, straight, hand-held probe is employed carrying two hand actuable switches. For tracking procedures, the probe is moved in an undulatory manner wherein the location of the radiopharmaceutical containing duct is determined by observing a graphics readout developed preferably employing a circularly accessed data memory. When the region of the sentinel node is approached, a switch on the probe device is actuated by the surgeon to carry out a sequence of squelching operations until a small node locating region is defined. At that point in the procedure, the straight small probe will be pointed at and in adjacency with the radiopharmaceutical containing sentinel node. The probe-mounted switches areconfigured to apply preset current levels upon the probe pre-amplifier power supply. These levels are detected, identified by a discriminator and emulating signals are generated. A sterilizable remote switch provides a squelch threaded level trim function.

Abstract: In the process for the continuous collection of pulverulent or dusty samples from a particle-laden stream, a sample stream is drawn off from a particle-laden main stream in a pneumatic conveying line 17 and passed via a collection line 9 to a particle size measurement device 10. In order to reduce spin, the main stream in the conveying line 17 is passed through a venturi-like cross-sectional constriction 3, 4, 5, the cross-sectional area of which is 10 to 60% of the free cross-sectional area of the conveying line 17. Samples are then collected downstream from the cross-sectional constriction through one or more probe tubes 7, wherein a partial stream is collected from the main stream parallel to the direction of flow thereof. In conjunction with a jet mill 14, into which the product to be ground and the propellant air are continuously introduced, the particle size distribution measured in the continuously collected sample stream may be used as a control parameter in order to adjust a parameter which determines particle size distribution of the jet mill 14 in such a manner that the particle size distribution in the product stream remains constant.
