Title: Arrangement for testing sections of digital electronic systems - checks address of section against test address before connecting section scan bus to system scan bus
Inventor: OHNESORGE DIETER DIPL ING
IPC: G06F11/267
Filed: 1990-11-27
Abstract: An arrangement for testing sections of digital electronic systems has limit sensing cells in the connections to the integrated circuits in the sections and controlled by a common control circuit. The cell inputs and outputs form a serial scan bus or scan path for the control circuit with at least one clock line and a control line. A further control circuit (STS) associated with a section controls its serial section scan bus (BAB) and forms the interface between the section scan bus and a higher level system scan bus (SAB). - The section busses are connected to the system bus depending on coincidence between an address defined by the actual position of the section (BG1....BGn) in the system and a test address for the section to be tested.

Title: Disposal of plastic food containers - using portable holder for stacked containers which are emptied into base for removal to disintegrator and reduced material is then reused
Inventor: KOPISCHKE JOACHIM
IPC: B03B9/06
Filed: 1990-12-17
Abstract: Equipment is designed to dispose of plastic packaging and, in particular, plastic containers for foodstuffs such as dairy produce. The empty containers are washed and placed in a cylindrical or square section portable holder (pref. made of plastics) whose i.d. matches the containers and which consists of two half-sections with ventilating gaps at the top and bottom made by spacers, this holder has a top cover which is opened for the purpose and the containers are stacked together until the holder is full, after which the cover is closed again. The container is taken to a moveable main container and emptied into bags of high tear strength plastic material fixed inside it, this procedure is repeated until the sack is full, when the sack is removed through a side door, sealed and temporarily stacked together with other similar sacks ready for transportation, all the filled sacks are finally passed to a disintegrator (partic. a mobile one) and reduced so that the sack contents can be reused in the prodn. of plastic articles. The sacks are pref. made of polypropylene or polystyrene and can contain also PVC. ADVANTAGE - The equipment and function prevent pollution of the environment by packaging plastics.
Patent DE-4107742-A1 (DE)
Inventor: ARNOLD WOLFGANG DIPL ING
IPC: H04Q11/04
Filed: 1991-03-11
Abstract: When a new protocol, e.g. the ETSI protocol T/S 46-30 in Europe, is introduced in all exchanges (VST), the ETSI protocol should be used in all terminals instead of the currently used protocol (e.g. the 1 TR6 in Germany) without hardware/software matching having to be carried out in situ. 
<??>For this purpose, the terminal is provided in advance with the two protocols (1TR6, ETSI-T/S 46-30) (e.g. in EEPROMs) and the current protocol is queried by means of a clear status enquiry, identifying the respective protocol, at the time of the conversion in the exchange, and the terminal is operated according to a status acknowledgement message identifying the protocol of the exchange.
