Inventor: SATOU HAJIME
IPC: B01J8/42
Filed: 1981-12-29
Abstract: PURPOSE:To permit efficient indirect heating of materials to be treated by forming a reacting tower body which constitutes fluidized beds of a waveguide, and absorbing microwaves in the microwave absorbing material provided in the waveguide thereby evolving heat. CONSTITUTION:In the stage of converting raw liquid uranyl nitrate to UO3 by thermal decomposition, UO3 powder is charged beforehand onto a diffusing plate 7 in a waveguide 2 and air is fed from an air supply device 9 to form fluidized beds. Thereafter, a soln. of uranyl nitrate is supplied from a liquid supply device 3 through a supply nozzle 4 and is heated by oscillating a microwave oscillator 1. The soln. of uranyl nitrate sticks on the UO3 powder and is dried by heating and is then denitrated to UO3 powder which is conducted, through a discharge line 8 into a recovering vessel 10. Here, about half of microwave energy is absorbed into the UO3 powder, and the rest is absorbed in a microwave absorbing material 6 to heat the UO3 powder indiectly.

Title: Controller for husking separator
Inventor: NINOMIYA SHINJI
IPC: B07B13/18
Filed: 1997-08-07
Abstract: PROBLEM TO BE SOLVED: To make it possible to adjust and set the appropriate number of oscillations and revolutions of a shaking separator. SOLUTION: The distribution data of paddy and unpolished rice is read by a paddy/ unpolished rice discriminating sensor 30 and the angle of transverse inclination of a shaking sepn. plate is read by a sepn. plate inclined movement (position) potentiometer 51. The number of oscillations and revolutions of an oscillation and rotation adjusting motor 60 is read. The paddy/unpolished rice discriminating sensor 30 is then moved to a transverse direction reference position and the number of revolutions of the oscillation and rotation adjusting motor 60 is adjusted to the initial number of oscillations and revolutions with respect to the detected angle of transverse inclination of the shaking sepn. plate. The number of oscillations and revolutions is then adjusted to increase by a prescribed revolution (2 rpm) each at every prescribed time.  Whether the detection data of the paddy/unpolished rice discriminating sensor 30 detects the boundary position between the paddy and the unpolished rice or not is decided. When the boundary polishing is not attained, the number of oscillations and revolutions is adjusted to a further higher side. When the boundary position between the paddy and the unpolished rice is detected, the number of oscillations and revolutions is decided to be appropriate and the adjusted to the higher side of the number of oscillations and revolutions is stopped. As a result, the number of oscillations and revolutions of the shaking sepn. plate may be adjusted and set to and at the correct number of revolutions by effectively utilizing the paddy/unpolished rice discriminating sensor 30 of the unpolished rice partition plate position controller.
