Title: Method and apparatus for granulation
Inventor: SPARKS ROBERT E
IPC: B01J2/28
Filed: 1991-12-18
Abstract: A method of melt granulation for powdery material is disclosed wherein the powdery material is discharged onto the upper surface of a heated rotary spreader (10) for migration under centrifugal force to the periphery of the spreader accompanying by melting of a portion of the material and enrobing of non-melted particles by the melted material for discharge as enlarged granules from the periphery of the spreader. To improve the quality of the granules produced, the feed material is supplied to the spreader at two separate locations. The first location is the central position (10a) of the spreader to provide the melted material and the second location is adjacent to the periphery (10c) of the spreader. The spreader is preferably in the form of a concave bowl or inverted truncated cone or dish. Feed material is supplied to the first location by a screw feeder (30) extending down the side of the dish and at the second location by a rotary vaned distributor (50) locatated within the dish which radially flings the feed material onto the inclined dish wall. The process and apparatus is particularly useful for the production of non-sticky granules which are difficult to form when a single central feed of material is used.

Title: Method of cleaning containers, a rinsing assembly and an apparatus for cleaning containers
Inventor: EGGER WALTER C
IPC: B08B9/093
Filed: 1993-06-22
Abstract: The invention relates to a cleaning method, in the case of which the containers (50) to be cleaned, which are all oriented in the same way, are moved in a row in a uniform manner along jet nozzles, one jet nozzle (15, 31 56), which guides a jet of the cleaning agent, being aligned in each case in a phased fashion, to the opening of a container. In contrast to a solution with a fixed jet nozzle, in this method, the jet nozzle (56) is forcibly made to follow, e.g. by a carrier (57), the opening of the container along a certain section of the path through which the latter moves. The associated advantage resides in extension of the active phase of the jet nozzle (56) and therefore in a high utilisation ratio of the cleaning agent. The jet nozzle (56) can be arranged on a spring-loaded pivot lever (55). A row of such jet nozzles, which move independently of one another, is provided for mechanical cleaning. A drag chain conveyor can be used to convey the containers, as this method is not very demanding regarding regularity of the distances of the conveyed containers from one another. <IMAGE>

Inventor: ROY DONALD
IPC: F24F12/00
Filed: 1993-07-06
Abstract: The present ventilating system is used for homes and buildings located in cold climate areas.  The system includes a heat exchanger for extracting heat from the inside air discharged to the exterior and transferring said heat to the outside air admitted into the building.  Blowers circulate air through the two paths of the heat exchanger and a motorized damper on the outside air path closes or opens the same.  An integrated circuit and the following sensors serve to operate the system as follows:  sensors detect the concentration of air contaminants, the humidity and the negative pressure of the air inside the building, while an outside air temperature sensor is also provided.  When the level of air contaminants is above an adjustable preset level,  the system operates in an inside air upgrading mode, namely air is circulated in both paths of the air exchanger; the same mode is used where humidity level is found to be excessive.  When negative air pressure is detected, the system is operated to admit only outside air within the building,  and if the outside air temperature is below a preset level, the system is operated in a heat exchanger de-icing mode for an adjusted time after each adjusted total time of system operation in either humidity or air-upgrading operating mode.

IPC: G06T5/20
Filed: 1993-12-21
Abstract: 23 PROCEDE DE TRAITEMENT DES IMAGES D'UN LOT D'IMAGES On élimine le bruit dans les images en effectuant une première transformée (11) de Fourier des images d'un lot d'images (I) originelles. On décompose ensuite chacune de ces images transformées (R,J) en série de Fourier (A, PHI, B, PSI) pour mettre en évidence les harmoniques principaux (M) d'une évolution périodique des images originelles et des images transformées. A partir de cette décomposition harmonique on recompose (14, 15) des images transformées (RH, JH) qui sont ainsi filtrées par abandon des harmonique non utiles. A partir des images transformées filtrées on effectue (16) une transformée de Fourier inverse pour obtenir en définitive des images originelles filtrées (F). On montre que le filtrage dans ce cas enlève le bruit sans altérer les structures de l'image, sans répartir le bruit parmi toutes ces structures. Figure 2.
