Patent DE-4001645-A1 (DE)
IPC: A61J1/03
Filed: 1990-01-20
Abstract: A known housing-type receiving device for a drug receptacle (for example a blister pack for coated tablets or the like) has at least one opening on the upper and lower sides which allows a drug to be pressed out of the drug receptacle using an actuating device associated with the receiving device. For automatically checking which drug (3') has been pressed out of a particular position inside the drug receptacle, the new receiving device (1) has an actuating device (2) movably coupled to the receiving device for pressing out each drug (3') located in a predetermined position. In addition, the actuating device (2) is associated with a position sensor (4) by means of which an instantaneous press-out position of an actuating element (8) of the actuating device (2) coinciding with the drug position can be sensed and determined. The position sensor (4) is connected to signal-generating and signal-processing means, for example optical and/or acoustic display means, which generate/emit/store or display position sensor signals characterizing the press-out position. Time-measuring means which determine the exact time at which any press out occurred are preferably connected to the position sensor.

Title: Automatic barrel weapon - incorporates drum with several cartridge locations and feed mechanism
Inventor: LANGOWSKI ANDREAS
IPC: F41A9/45
Filed: 1990-03-21
Abstract: The feed mechanism of the weapon brings a cartridge to a free holding location in the drum.
