Patent DE-4010117-A1 (DE)
Title: Electronic surveying apparatus e.g. tacheometer or theodolite
Inventor: KATO TOSIHIRO
IPC: G01C1/02
Filed: 1990-03-29
Abstract: The surveying apparatus includes a keyboard, a display, and a card-receiving portion in which a memory card is inserted to record the survey details and data. Since signals and power are transmitted to the card electromagnetically, the use of contacts on the card can be eliminated, rendering the arrangement less subject to effects of dust and water. Since an inserting portion in which the memory card can be detachably inserted is formed in a columnar portion of the apparatus main body, a keyboard section can be arranged on either side of the apparatus main body. The survey data and other information required for a survey are stored in a storing/operating section and are recorded in a memory section of a memory card and the information required for a survey are input to the memory card in advance, and are also stored in a microcomputer of the surveying apparatus or the data in the memory card is transferred in response to a command from an external unit.

Inventor: BLASIUS UFO
IPC: B41F13/12
Filed: 1990-05-08
Abstract: In a method for indicating registering device malfunctions on a printed product equipped with registering marks (4, 5, 6), the registering marks (4, 5, 6) being scanned opto-electrically on passage of the printed product through the printing machine, the registering marks (4, 5, 6) are scanned twice in the direction of travel of the web at a predetermined separation.

Title: Rotor spinning sliver supply - has grip at can to form sliver to point and insert it into the spinner feed
Inventor: KROUPA PETR DIPL ING
IPC: B65H67/06
Filed: 1991-03-07
Abstract: The supply system for passing sliver to the workstation of a rotor spinning machine severs the sliver at a given gap from the can filling station when the can is full and is clamped temporarily in a holder at the edge of the can while it is moved onwards, and the free end of the sliver is twisted into a point, for holding in the grip with a given over size. At each spinning station, the grip orients the firm point of the sliver end at the entry into the sliver compressor and advances it between the opened feed units. The sliver is then drawn out of the can to be fed to the spinner. From the time that the sliver is cut at the filling station, until it is fed into the compressor at the feed side of the spinning station, it is constantly held by the grip, which is operated externally. ADVANTAGE - The technique gives a safe movement of the sliver and the cans to the spinning stations to give an automatic and trouble-free insertion of the sliver into the spinning workstation.
