Patent CZ-174696-A3 (CZ)
Title: Method of monitoring at least one safety-related function of an apparatus
Inventor: KRIEGER KLAUS
IPC: G05B19/042
Filed: 1994-12-05
Abstract: A process is disclosed for monitoring at least one safety-relevant function of a machine. The machine has two or more microprocessors (10a, 10b) interconnected by a data bus (11). Every time the machine is started (42) the master function is allocated to another microprocessor (10a, 10b). Only the master processor can trigger the process (20a, 20b) required to start (42) the machine. A programmable and erasable memory (EEPROM) (13a, 13b), in which operation states of the machine, detected faults, locking marks or cue signals may be stored, is associated to each microprocessor (10a, 10b). As the master function alternates between the microprocessors (10a, 10b), at each moment in time different programmes are processed in the microprocessors (10a, 10b). Occasional faults, in particular those caused by electromagnetic interference, have a different effect and may thus be distinguished from serious faults. This process is for example suitable for a fuel-heated machine or for example in controllers preferably built into motor vehicles.

Patent CZ-399198-A3 (CZ)
Title: Uniformly dispensing tube magazine with several chambers
Inventor: CONNAN PATRICK A
IPC: B65D35/22
Filed: 1997-05-21
Abstract: A multichamber container must have certain characteristics in order to uniformly dispense the contents of each chamber from the container. The outer wall of the container and the inner divider web walls must have certain characteristics. The inner divider web walls must be highly flexible while the outer container wall must be less flexible. The Deflective Force for the outer wall must be greater than the Deflective Force for the web walls. In addition, to alleviate the problem of suckback of air into the container chambers, the outer wall should exhibit a specific Retention Index. This is a measure of the outer wall to remain deflected after the removal of the deflecting force. The inner divider web wall will have a lower Retention Index than the outer wall. By the proper selection of outer wall and web walls, there can be uniform dispensing from the dispenser.
