Patent CA-2169039-A1 (CA)
Inventor: ETTMUELLER PETER
IPC: F42B12/58
Filed: 1996-02-07
Abstract: It is possible by means of this device to fill a shell body with sub-projectiles in a defined geometric arrangement in a very short time without errors being created by shifting.  Prior to filling, the sub-projectiles (20) are combined into layers (40) for this purpose, which are as thick as the length of the sub-projectiles (20) and which extend in planes transversely to the longitudinal axis (43) of the shell body.  The sub-projectiles (20) take up a position in the layer (40) which corresponds to their geometric arrangement in a hollow chamber (42) of the shell body.  During the combination, the circumference of the layers (40) is shaped in such a way that, following the insertion of a layer (40) into the hollow chamber (42), the sub-projectiles (20) are held therein fixed against relative rotation while maintaining the previously formed geometric arrangement.  In accordance with a preferred embodiment, the circumference of the layers (40) has the shape of a regular hexagon, wherein the axes of the sub-projectiles (20) consisting of cylinders extend parallel with the longitudinal axis (43) of the shell body.

Title: Swirl flow ozone generation
Inventor: KARLSON ESKIL L
IPC: C01B13/11
Filed: 1994-07-19
Abstract: Ozone is generated from an oxygen-containing gas utilizing a tube-type ozone generator at significantly greater power efficiency. The oxygen is introduced into the annular passageway between the electrodes of the tube-type ozone generator at an angle (e.g. about 45-90.degree.) so that it swirls in a cyclonic flow path as it travels from one end of the annular passageway to the other. The amount of power consumed to produce a gas having about 8 % ozone is roughly half of the power needed if the same conditions are applied but the oxygen gas is introduced conventionally (without swirling action, so that it travels along the dimension of elongation of the passageway). The swirling action also allows a higher concentration of ozone (e.g. 10 % or more) to be achieved in the product gas compared to the same conditions when no swirling is employed. Cooling fluid, such as nitrogen gas, may be passed through an interior passageway and outside the outer electrode either co-current or countercurrent to the general direction of oxygen gas flow.

Patent CA-2188005-A1 (CA)
Inventor: LULLI ALFREDO
IPC: G01B9/02
Filed: 1996-10-16
Abstract: An optical three-dimensional profilometry method in  which  are recorded  SPECKLE  images  formed by  the interference,  due to different optical  paths,  of the rays reflected/diffused by a rough object and the rays generated by a beam source. The method presents a number of processing steps including the steps of digitizing a first  SPECKLE  image,   modifying  the  optical  path difference,  and  digitizing  a  second  SPECKLE  image recorded after modifying the optical path difference.          The  difference  in  the  modulus  of  the  corresponding pixels  of  the  first  and  second  digitized  images  is determined  to  generate  a  difference  image  which  is subsequently  analyzed,  a  first  arbitrary  value  is assigned to all the difference image pixels exceeding a given threshold value, and a second arbitrary value is assigned to all the difference image pixels of a value below the threshold. The binary image so generated is processed to generate an artificial image in which all the binary image pixels equal to the second arbitrary value are assigned a zero value,  and all the binary image pixels equal to the first arbitrary value are assigned a current processing step value. The processing steps are repeated cyclically for a predetermined number of steps to generate a depth map presenting a number of pixels,  each presenting a grey level corresponding to the  last processing step  in which the threshold was exceeded, and the depth map contains three-dimensional information relative to the profile of the rough object under examination.
