Title: Color ink jet recording method and apparatus using black ink and color-mixed black ink
Inventor: MORIYAMA JIRO
IPC: H04N1/58
Filed: 1993-10-29
Granted: 1999-10-12
Abstract: Whether or not a color image is present adjacent to a black image is discriminated. Whether the black image is formed using a black ink or a plurality of color inks C, M, and Y is determined in accordance with the discrimination result. When the black image is formed using the plurality of color inks, it is recorded using a repetitive pattern of two of C, M, and Y so as to prevent blurring with the color image, and to improve fixing characteristics by decreasing the total ejection amount.

Abstract: System for monitoring the angle-of-attack of the wheelsets  of  a railway vehicle moving along a  track section.    The  apparatus  includes  a  rangefinder  to repeatedly measure at known intervals the instanteous distance  between  a  reference  point  and  successive registering points on a face plate surface of a wheel of a  passing wheelset.    A  detector  generates  a  signal representative of the velocity of the wheel passing along the reference point.   A computer receives the output signals  generated by the velocity sensor and  of the rangefinder  to  compute  the  angle-of-attack  of  each wheelset.

Abstract: New compositions based on ceric oxide exhibiting an improved ability to store oxygen, these compositions being characterised in that, besides ceric oxide, they contain at least one oxide of another metallic element M chosen from the group consisting of iron, bismuth, nickel, tin and chromium or one of their mixtures, this oxide being preferably in solid solution with the abovementioned cerium oxide. The process for the synthesis of these compositions consists in first of all preparing an intimate mixture of (i) a ceric oxide or hydroxide and (ii) at least one additive consisting of a hydroxide or a salt capable of being thermally decomposed to oxide, of the metallic element M, and in then calcining this mixture so as to obtain the desired oxide-based composition. The compositions according to the invention are particularly useful in the manufacture of catalysts and/or catalyst supports, especially those intended for the treatment of the exhaust gases of internal combustion engines.

Title: Assembly for the unwinder end of an off-machine paper web handling line
Inventor: RAUTIAINEN PENTTI
IPC: B65H19/18
Filed: 1994-02-17
Granted: 2002-10-29
Abstract: When a new roll is changed in an off-machine coating line into the unwinder (1), problems are encountered in matching the tension of the web (16) received from the expiring roll (13) to that to be paid off from the new roll (12). Differences in web tension cause web breaks during roll change. According to the invention, the web is supported at the unwinder (1), and subsequently, at the following dryer cylinder group (2) by means of a support felt (3) serving to the end of equalizing differences in web tension. The web received from the first roll (13) is spliced to the tail of a second, full roll (12) by pressing the web (16) received from the first roll against the web of the second roll via a support felt (3) by means of a splicing roll. Next, the web is fed supported by the felt (3) to a dryer cylinder group (2) comprising VAC and steam cylinders (20, 21) where the damp web is dried for subsequent coating.

Title: Pyrolytic deposition in a fluidized bed
Inventor: ACCUNTIUS JAMES ALBERT
IPC: C23C16/44
Filed: 1992-06-05
Granted: 1999-08-31
Abstract: Precise control of pyrocarbon being coated upon an object in a fluidized particle bed is achieved by monitoring the pressure difference between a region above the bed and a region in the lower portion of or just below the bed. Measurement of such pressure differential has been found to be truly representative of bed size in such a coater, and bed size is recognized to be a most important factor in achieving the desired characteristics of the substance being deposited. By adjusting bed size in response to changes in the pressure difference being monitored, a substantially constant bed size is readily achieved; alternatively, the pressure difference can be caused to gradually change in accord with a predetermined program. In either instance, adjustments are effected by adding additional particles to the bed or by changing the rate at which particles are withdrawn, and precise coating characteristics, e.g. thicknesses within very close tolerances, are achievable.

Title: Magnetic roller gas gate employing transonic sweep gas flow
Inventor: DOEHLER JOACHIM
IPC: H01L21/205
Filed: 1994-02-14
Granted: 1998-09-22
Abstract: Disclosed herein is an improved gas gate (42) for interconnecting regions of differing gaseous composition and/or pressure. The gas gate includes a narrow, elongated passageway (92) through which substrate material (11) is adapted to move between said regions and inlet means (93) for introducing a flow of non-contaminating sweep gas into a central portion of said passageway. The gas gate is characterized in that the height of the passageway and the flow rate of the sweep gas therethrough provides for transonic flow of the sweep gas between the inlet means and at least one of the two interconnected regions, thereby effectively isolating one region, characterized  by one composition and pressure, from another region, having a differing composition and/or pressure, by decreasing the mean-free-path length between collisions of diffusing species within the transonic flow region.  The gas gate preferably includes a manifold at the juncture point where the gas inlet means and the passageway interconnect.
