Title: Apparatus for effecting heat exchange between a liquid and a particulate material
Inventor: MOSSE RICHARD W E
IPC: A23L5/10
Filed: 1992-11-20
Abstract: APPARATUS FOR EFFECTING HEAT EXCHANGE BETWEEN A LIQUID                AND A PARTICULATE MATERIAL                 ABSTRACT OF THE DISCLOSURE      Apparatus  for  heating  and/or  cooling  a  particulate material, e.g. vegetables, by heat exchange with a liquid comprises a horizontal tubular chamber of waisted internal cross-section containing a rotatable mesh cylinder having an auger blade corotatable therein.  A row of inlets for heat exchange liquid along the bottom of the chamber are connected via external pipe work to a row of outlets for heat exchange liquid at the top of the chamber.   Upward flow of heat exchange liquid causes suspension of particulate matter as it is conveyed through the chamber by the auger, thus minimising rubbing contact on the particulate material.  The apparatus includes a heating section defined by inlets A-D, a holding section defined by inlets E to L,  and a cooling section defined by inlets M to Q, all within a common chamber.  Within each section,  each outlet is connected externally to the alphabetically preceding inlet except for the leftmost outlet which is connected to the rightmost inlet.  The heating and cooling  flows  recover  heat  via  a  regenerative  heat exchanger.

Patent CA-2085651-A1 (CA)
Title: Adjustable waveguide branch, and directional coupler
Inventor: MEISE WILLIAM H
IPC: H01P5/04
Filed: 1992-12-17
Abstract: Abstract of the Disclosure A rectangular waveguide series junction has a layer of photoconductive material in one branch near the junction. The photoconductive material, when dark, is essentially a dielectric, which effectively increases the dimension of the waveguide branch over what it would be if not modified, thereby increasing its impedance at the series junction and causing power division preferentially into the branch. When illuminated, as by a laser or LED, the photoconductive layer becomes a conductor instead of a dielectric, and the dielectric "increase"in the dimension is eliminated. Instead, the conductive material actually decreases the cross-section, to thereby reduce the actual impedance of the branch at the junction point. This reduces the amount of coupling below that for an unmodified waveguide branch. Thus, the amount of coupling into the branch at the junction is increased by the dielectric constant when the photoconductor is dark, and decreased by the conductivity when illuminated. A waveguide directional coupler includes one or more such controllable branches. Redundant light emitting diodes are located in slots adjacent the central seam of the directional coupler housing, for fine control of the coupling factor. Control may be applied to move nulls in the coupler isolation to reduce interference in antenna arrays, to adjust coupling to achieve improved channel-to-channel isolation, or to compensate for aging, or other changes of amplifiers or other circuit components.

Inventor: MOORE WILLIAM P
IPC: C05F11/00
Filed: 1993-03-04
Abstract: A continuous process for the non-destructive recov-ery of natural nitrogenous materials as highly available particulate agricultural nutrients is described. The pro-cess employs natural materials such as poultry waste, waste water treatment sludge, alfalfa meal, hatchery waste, fea-thermeal, corn gluten meal, and bloodmeal in a fluid bed reactor-granulator. The natural materials, which are basic in nature or have been made basic, are acidified to pHs of about 3.0 to 6.5 in the reactor-granulator and formed into hardened particulates during a retention time of between about 4 to 20 minutes at a temperature between about 70-120°C. The particulates are discharged free of carameliza-tion and before nitrogen loss from decomposition amounts to 0.5 percent of the natural nitrogenous materials. The con-tinuous process provides a new natural nitrogenous particu-late agricultural nutrient composition free of carameliza-tion.
