Abstract: IONIZATION PARTICLE DETECTOR                      ABSTRACT   An ionization particle detector for indicating the presence of charged particles in a gas includes a single ionization chamber having two defined regions of electrical field intensity.  The first region is of small geometric volume and high electric field intensity while the second region is of large geometric volume and low electric field intensity.  The radioactive source for generating the ions is located near one electrode while the second electrode forming the walls of the chamber are located such that the walls are incident near the Bragg ionization peak of the detector.  A probe is positioned between the two regions for detecting the maximum electric field change when particles enter the chamber.

Abstract: SPRAY DRYING APPARATUS UTILIZING PULSE JET ENGINES             Abstract of the Disclosure Spray drying apparatus is disclosed wherein circumferentially spaced apart exhaust pipes of three L-shaped pulse jet engines extend upwardly into the floor of a cylindrical drying chamber. The engines extend radially outward beneath the floor of the drying chamber, with the engine inlet openings being supported in spaced apart juxtaposition with air augmentation ducts which extend upwardly and tangentially into the drying chamber at equally spaced apartpositions near the drying chamber floor. Moisture laden material, such as a slurry that contains the material to be dried is introduced into the upwardly directed exhaust stream of each engine by means of feedpipes which pass coaxially along the interior of each engine exhaust pipe and an injection nozzlethat is affixed to the terminus of each feedpipe at a predetermined distance below the engine exhaust opening. The hot flowing exhaust gases and broad band acoustic energy supplied by the engines atomizes or divides the injected material and causes a substantial reduction in moisture content as the injected material passes to the drying chamber. Moisture removal continues as the material is borne upwardly through and about the drying chamber by the engine exhaust and airflow introduced by the augmentation ducts. The portion of the material reaching the top of the drying chamber is removed through a product outlet opening and the portion falling to the drying chamber floor is swept circum-ferentially around the chamber floor by the tangentially directed streams of 'air supplied by the air augmentation ducts. A conventional screw type conveyor that extends across a portion of the chamber floor receives and removes this portion of the material.
