Title: Deep ripper point
Inventor: WILLIAMS ROBERT A
IPC: A01B15/02
Filed: 1992-01-10
Abstract: DEEP RIPPER POINT Abstract The point is adapted to fit onto the forward-ly projecting mounting wedge of a tillage shank and has a downwardly and forwardly inclined, elongated  crown provided with a transverse, sharpened tip at its lower front end.  An underslung transverse wall looped under the crown at the front end of the point defines a rearwardly opening socket that matingly receives the apex of the mounting wedge of the shank, and depending sidewalls on the crown adjacent its opposite lateral edges  rearwardly  of  the  underslung  wall  serve  to present a protective trough on the underside of the crown that matingly receives the upper surface of the mounting wedge so as to protectively cover otherwise exposed side portions of the wedge and thus shield such areas from exposure to abrasive soils.  Two alternate embodiments are disclosed, one of which has lateral side edges of the crown intersecting cleanly with upright surfaces of the underslung wall and the side-walls, and the other of which has side edges of the crown overhanging such structures and provided with a certain vertical thickness dimension.

Title: Method of counting particles
Inventor: ASANO KAORU
IPC: G06M11/00
Filed: 1992-06-03
Abstract: A method of seeking the number of particles of each kind in a group of particles in which plural kinds of particles are intermixed, by measuring, for example, two kinds of properties of each particle by a suitable method or device, plotting each particle on a rectangular co-ordinate system using the measured properties as its X and Y co-ordinates to obtain a distribution diagram, drafting boundaries to partition the distribution into clusters of the respective kinds and counting the number of particles within the boundary of each cluster, which, especially, even when the clusters of the respective particles are mutually overlapping, can reduce any deviation of the count of particles from its true value as much as possible by defining an optimum boundary.  In this method, a center of gravity of each cluster is determined, a degree of attribution of each particle to each cluster is calculated based upon a distance of each particle from the center of gravity and the number of particles belonging to each cluster is counted in consideration of the degree of attribution.

Patent CA-2074976-A1 (CA)
Inventor: GERSTMANN JOSEPH
IPC: F24H1/43
Filed: 1992-07-30
Abstract: Combustion apparatus (10) includes a combus-tion chamber (12, 212), a cover (24, 208) covering an end wall (14, 210) of the combustion chamber and defining a buffer space (26, 206) therebetween, and a blower (32, 202) external to the cover and supplying air to the buffer space and pressurizing the buffer space to a higher pressure than the combustion chamber such that leakage at penetrations (46) and/or interfaces (334, 336) flows from the buffer space into the combustion chamber, rather than the reverse, eliminating the need for leak-tight seals, and instead permitting leakage in a desired direction. The sum of pressure drops (R1 + R2) from the blower to the mixer and burner assembly and from the mixer and burner assembly to the combustion chamber relative to that (R5) across the combustion chamber exhaust outlet (22, 220) is higher than the pressure drop (R3) from the blower to the buffer space relative to that (R4) across the buffer outlet (30) at the penetrations. In one embodiment, a first conduit (58) supplies air along a path (34) from the blower to the mixer and burner assembly without passing through the buffer space, and a second conduit (60) independently supplies air from the blower to the buffer space. A pressure dropping orifice (36) is provided between the blower and the mixer and burner assembly. A gas inlet port (40) is external to the cover (24) and downstream of the pressure dropping orifice (36). The buffer space (26) communicates with the blower (32) along an air flow path (44) upstream of the pressure dropping orifice (36). In another embodi-ment, air flows through the buffer space (206) to the mixer and burner assembly. The buffer space (26, 206) is thin and flat, and the cover (24; 208) covers only one end wall (14, 210) of the combustion chamber, not the other end wall nor the sidewall, such that the latter are accessible without removing the cover.

Filed: 1993-01-29
Abstract: In a hydrocracking process a feed mixture comprising: heavy oil containing asphaltenes and sulfur moieties; an oil-soluble,  metal-containing  compound  additive  (such  as  iron pentacarbonyl or molybdenum 2-ethyl hexanoate), which additive is operative to impede coalescence of coke precursors and which forms hydrocracking catalytic particles in situ; and, optionally, a hydrocarbon diluent which is a solvent for asphaltenes and which will assist with dispersion of the additive; is mixed for a prolonged period at low temperature (e.g. 80°C - 190°C) in a first  vessel  or  vessels  to  disperse  the additive  without significantly decomposing the additive.  Preferably, the product mixture is then digested in a second vessel or vessels by mixing it at an elevated temperature (e.g.  250°C), to decompose the additive.  The resulting mixture is then heated to hydrocracking temperature  (e.g.  450°C)  and introduced into a reactor.   A hydrogen flow, sufficient to maintain mixing in the reactor and efficient (e.g. greater than 98%) stripping of light ends (e.g end point  boiling  220°C),  is  provided.    The  steps  of  low temperature  mixing  to  achieve  dispersion  without  additive decomposition, preferably digesting to decompose the additive under  mixing  conditions,  and  mixing  in  the  reactor  with stripping, combine to yield well dispersed, colloidal catalytic particles which function to impede coke evolution and provide high conversion of the high boiling (504°C+)  fraction of the feedstock.

Filed: 1993-03-10
Abstract: A blender (10) includes a pitcher assembly (11), a motor and housing assembly (12) and a cooling fan and noise muffling assembly (13). The pitcher assembly (11) includes a blender pitcher (14) having a mixing blade (15) therein driven by a motor (24) positioned in the housing assembly (12) which includes a base frame (31) and a cover (21). The motor (24) is positioned in a pedestal (37) formed in the base frame (31). The base frame (31) is provided with air intake apertures (53, 55). The fan and noise muffling assembly (13) includes a radial fan (60) driven by the motor (24) and a muffler housing (62) which includes a generally cylindrical side wall (68). Air is drawn in through the apertures (53, 55) by the fan (60) and is caused to pass by the motor (24) within the pedestal (37) to cool the motor (24). It then passes through an aperture (66) in an orifice plate (61) and as directed by the fan (60) against the side wall (68). At that point the air turns ninety degrees downwardly and is directed into four chambers (73) below the fan (60), the chambers (73) being formed by ribs (74) extending radially outward from a hub member (75) positioned below the fan (60). The air then again turns ninety degrees inwardly into two chambers (76) divided by a rib (77) below the hub member (75) whereby it turns again and leaves the blender (10) through an air exit aperture (70).
