Patent EP-0312755-A3 (EP)
Title: Conveyor for continuously supplied flat products, in particular prints
IPC: B65H5/14
Filed: 1988-09-08
Abstract: Individually controllable gripper elements are successively spacedly arranged at a ball-and-socket joint-link chain revolvingly driven and guided in a guide channel. At the leading end region of an overhang member of each gripper element there is seated a clamping jaw and at the trailing end region there is arranged a bushing. A shaft is rotatably and displaceably mounted within the bushing. A clamping finger, coactable with the clamping jaw, is rigidly connected with the upper shaft end. At the lower shaft end there is seated a slide shoe and the lower end region of the shaft is encircled by a pivotable element rotatably connected with the shaft. A compression spring rigidly bears for rotation at the pivotable element and the overhang member. When the slide shoe travels onto a stationary cam the clamping finger is raised against the force of the compression spring. An actuation element, which acts upon a further slide shoe, rotates the clamping finger through an angle of about 90 DEG . In this position the slide shoe at the lower end of the shaft travels off the stationary cam, resulting in the clamping finger bearing upon the clamping jaw. Since the compression spring is pre-biased in the direction of the open position of the clamping finger the latter can pivot back into the open position by slightly raising the slide shoe at the lower end of the shaft.
Patent EP-0311111-A3 (EP)
Title: Apparatus for assembling data for supply to a scanning output device
IPC: G06K15/00
Filed: 1988-10-07
Abstract: A device controls in real time the assembly of 
data for a bit map scanning device such as a laser 
printer under supervisory control of a host processor. 
The image data words are stored in a source memory and 
assembled in a video buffer, and automatically scanned 
out to the scanning device. The host processor 
generates a simplified set of control words that 
defines graphics, text and layout of the page to be 
assembled. An arithmetic logic unit ALU takes care of 
address calculation for all interfaces. A barrel 
shifter provides for bit alignment of the image data 
words in the video memory. Also, background and color 
combination logic combines the fonts and graphics with 
background and texture information. A raster 
interface synchronizes the output of the assembled 
data with the scanning device. Three basic modes are 
supported: 1) dispatch mode, 2) font read/write 
mode, and 3) graphics load mode. The dispatch mode is 
the normal operational mode which provides for 
dispatching data from a source memory location to the 
video memory for supplying data from the video memory 
out to the raster printer. The font read/write mode, 
gives the host the ability to read/write font or 
graphics data from/to the source memory or the video 
memory. The graphics load mode provides for transfer 
of a bit-mapped window of data to the video memory. 
The video memory can be divided into two video bands. 
While one of the video bands is being read for supply 
 
 
of output data to the scanning device, data in the 
second band is being filled with font and graphics 
information using dispatch. After scanning all data 
out of the first band, the apparatus switches to the 
second band for printing and refills the first band 
with new data using dispatch.

Title: Device with a cable drum for lifting or lowering a person under his own control
IPC: B66D1/04
Filed: 1988-12-16
Abstract: The carrying line (5) on which a person can be suspended by means of a safety harness is lowered or raised in a controlled manner via the cable drum (1). The endless drive cable (16) running over the drive wheel (15) serves to control the movement. The lifting is effected by the suspended person pulling on one side of the cable, by the control and drive mechanism (12) via the reduction gearing (14), whereas the friction coupling between the drive wheel (15), the notched wheel (21) with the friction linings (210, 211) and the flange sleeve (20) of the main shaft (2) is released by pulling on the other side of the drive cable (16), and the controlled and braked lowering is effected by the drive cable. When the person lets go of the drive cable (16), full braking is immediately effected. The catches (24) engaging in notches (22) provide a safeguard against return travel during lifting. The device can be used for any activity on perpendicular walls or masts where secured suspension from the topmost part is possible. The advantage consists in the fact that the person fastened to the device can move up or down without an additional aid and can be secured and can work with both hands when stopped. <IMAGE>
