Patent DE-19733442-A1 (DE)
Inventor: DOELVES JUERGEN HEINRICH FRITZ
IPC: B41C1/04
Filed: 1997-08-02
Abstract: The invention relates to a method for engraving printing cylinders used for rotogravure in an electronic engraving machine. According to this said method, at least two engraving sections (A, B) of a given width (SB) are fitted next to each other, in the acial direct ion of the printing cylinder (1). These sections (AB) are engraved with their respective engraving element (3). Before engraving, an axial reference position is pre-set for each engraving element (3). The axial spacing between these reference positions corresponds to the pre-set widths (SB) of the engraving sections (A, B). The engraving elements (3) are placed approximately in their reference positions (RP). The differences in the axial spacing between the reference positions of the engraving elements (3) and the actual positions occupied as a result of the approximate positioning are then measured. During engraving, the engraving elements (3) are moved along the printing cylinder (1), still incorrectly spaced as a result of the approximate positioning. The spacing errors are compensated by displaced engraving of the engraving sections (A, b) on the printing cylinder (1), so that the engraving sections (A, B) have the pre-set widths (SB) despite the incorrect spacing between the graving elements (3).

Patent DE-19749951-A1 (DE)
Title: Short-term starting of power plant equipment
Inventor: TEEGE LOTHAR
IPC: F22B35/00
Filed: 1997-11-03
Abstract: The quick starting process involves pressurizing all the system necessary to start the power plant, particularly the boiler, using steam from the steam storage capacities of the failed steam boiler plants.  When the firing of the steam storage capacity of the failed boiler has been switched off, all the steam-consuming systems are blocked off in all directions. The amount of storage steam is kept at a maximum by reducing the negative pressure in the fire cavity and by blocking off the input systems of the cooling process for the failed steam boiler.

Patent DE-19807578-A1 (DE)
Title: Free wheel clutch for e.g. four-wheel drive vehicle
Inventor: DICK WESLEY M
IPC: F16D41/08
Filed: 1998-02-23
Abstract: The clutch has two (12,16) torque transmission shafts which may both rotate in both directions and which are both coupled to separate power input points. The shafts are separated by a purely mechanical bi-directional clutch (10) with reverse (46) section. The bi-directional free wheel clutch limits the differential effect, or the difference in relative speed of rotation between the front and rear wheels. The clutch facilitates a relative over-speeding or a differential effect between the front and rear wheels up to a given threshold value. When this threshold is surpassed, then part of the excess torque from the axle with the slipping wheel is transferred to the axle with the non-slipping wheel.
