Title: Printing press comprising impression cylinders having replaceable sleevelike impression cylinder shells
Inventor: LUBKE HERBERT
IPC: B41F13/20
Filed: 1990-11-26
Granted: 1997-04-29
Abstract: An impression cylinder provided with a replaceable sleevelike impression cylinder shell is movably and releasably mounted in a printing press by means of a bearing in such a manner that the im-pression cylinder adjacent to its one stub shaft is adapted to protrude freely from the machine frame so as to permit a replacement of the impression cylinder shell. In order to permit a particularly simple re-placement of the impression cylinder shell, the bearings consist of hinged bearings having bearing shell sections which can be swung off to a position in which they permit the impression cylinder to be swung out in a horizontal plane. The impression cylinder is provided at one end with a stub shaft, which extends beyond the associated hinged bearing and which at the top of its end portion supports a supporting shell section, which is axially immovably mounted in the machine frame for rotation about a vertical axis. A movable horizontal supporting rail or slideway is provided, which is movable from below into engagement with the impression cylinder, or with a shaft portion connected to said cylinder, at a location between the bearings, and is adapted to be fixed in position, so that the impression cylinder which is held between the supporting shell section and the supporting rail can be pivotally moved out of the opened hinged bearings about the vertical pivot for the supporting shell section.

Title: Apparatus for controlling and protecting a vehicle seat suspension
Inventor: BRODERSEN COLE T
IPC: B60N2/52
Filed: 1991-07-11
Granted: 2000-10-31
Abstract: A device is disclosed that overrides the manual controls for filling and emptying an air suspension spring, so that the spring is not over-filled or under-filled. The device also includes a mechanism for limiting the rise of the seat suspension when the driver exits the seat. The invention has a latch bar that slides through two pieces of lubricating plastic. A ramped section of the latch bar contacts one of two switches that prevents the adjustment of a seat suspension below a minimum safe ride position or prevents adjustment above a maximum safe position. The latch bar also includes notches that are engageable with a latch pawl that is operated by a solenoid. When an operator leaves the seat, the solenoid is energized and drives the latch pawl into a notch in the latch bar. An electronic switch also enables the deenergizing of the solenoid, yet the latch pawl locks the latch bar so that the air spring does not cause a substantial rise in the seat suspension.

Granted: 1999-08-10
Abstract: The in vivo chemotherapeutic treatment of cancer cells in a living animal is improved by first administering to the animal an antagonist specific for intracellular histamine in an amount sufficient to inhibit the binding of intracellular histamine in normal cells. An enhanced toxic effect on the cancer cells from the chemotherapeutic agent is obtained while any adverse effect of the chemotherapeutic agent on normal cells is inhibited. In addition, long term continuous administration of the antagonist following administration of the chemotherapeutic agent results in at least amelioration of the adverse side effects of chemotherapy. The treatment of cancer cells using DPPE specifically illustrates the invention.

Abstract: The techniques for determining the orientation of lines in images disclosed herein take as their starting point an apparently universal typesetting convention: that symbols are generally closer to other symbols in the line to which they belong than they are to symbols in other lines. The techniques make a graph by connecting symbols in an image of a block of text with edges (lines) and then determine thepredominant orientation of the shortest edges. Because the symbols in a line arecloser to each other than to symbols in other lines, the predominant orientation of the shortest edges will be the same as the orientation of the lines. An advantageousmode of obtaining the shortest edges is to construct a Euclidean minimum spanning tree from the graph. A Euclidean minimum spanning tree of a graph contains all the nodes (symbols) of the original graph but connects the nodes with the shortest possible set of edges. The edges which predominate in the Euclidean minimum spanning tree are the shortest edges. Which edges predominate is determined by means of a histogram.
