Title: High-availability computer system with a predefinable configuration of the modules
IPC: G06F11/00
Filed: 1989-04-27
Abstract: An arrangement providing a simple, rapid and flexible 
identification of the modules within a computer system during 
the initialization and identification phase subsequent to 
startup. A pre-defined, that is, previous to startup, 
configuration is implemented during initialization and 
identification phase without significant additional hardware 
costs. Each of up to 32 modules is connected to a different 
lead of a 32-bit wide parallel bus. During initialization, 
starting with the least significant bit position and 
progressing to the most significant bit position, one and only 
one position of the 32-bit parallel bus is driven to logic 1. 
The module exclusively connected to that bus bit position lead 
is selected to receive its pre-defined identification and 
configuration storage. Thus, when all modules have in turn 
been supplied with the initialization information, the next 
phase can begin.

Patent EP-0370828-A3 (EP)
Title: Electric power installations, especially for office furniture
IPC: H02H11/00
Filed: 1989-11-24
Abstract: An electric supply installation, primarily intended 
for office furniture and like applications, includes a 
number of power supply sockets connected in a chain. A 
control unit is interposed between one end of the chain 
and the mains supply, and a pilot conductor is 
separately connected from the control unit via an 
impedance to the earth contact at the far end of the 
chain. This impedance forms part of a potential divider 
through which a pilot current flows to establish a pilot 
potential on the pilot conductor, and comparator means, 
such as a window comparator, monitors this pilot 
potential and disconnects the live pole if the pilot 
potential falls either above or below a preset range of 
values. This ensures disconnection on failure of 
continuity either in the main earth connection or in the 
pilot conductor itself.

Patent EP-0568791-A3 (EP)
IPC: B29B17/02
Filed: 1993-03-09
Abstract: The invention relates to a process for recycling packaging materials containing one or more synthetic polymers and/or metal and/or natural polymers, with dissolution of the synthetic polymer component in a solvent and recovery of soluble and insoluble packaging constituents.   The object of the present invention is to develop an inexpensive and environmentally friendly process for recycling packaging materials containing one or more synthetic polymers and/or metals and/or natural polymers, in particular packaging composites. The disadvantages of the known processes are to be substantially avoided. In particular, the synthetic polymer component should be separated off in a manner suitable for recycling. The other components in packaging composites, such as the natural polymers present in cardboard (board) and paper, in particular cellulose, and metal, in particular aluminium, are likewise to be obtained entirely as individual components suitable for material recycling. This object is achieved according to the invention by a process in which the packaging materials to be recycled are treated with a solvent comprising aliphatic, naphthenic or aromatic hydrocarbons, hydrogenated products thereof or a mixture thereof. The solvent treatment is carried out until the synthetic polymer component has dissolved. The treatment temperature is between 0 and 500 DEG C. The solvents employed are, particularly, boiling fractions from primary and secondary petroleum refining whose boiling limits are in the range between 40 and 500 DEG C. The result of the treatment process is a liquid mixture of hydrocarbons of various structure and molecular weight in which the insoluble packaging constituents are dispersed. These insoluble packaging constituents, such as cellulose residues and aluminium, are separated from the liquid phase. The separation of the insoluble packaging constituents is followed according to the invention by the separation of the dissolved polymer component from the liquid mixture.

Title: Method for routing of calls in a private virtual network and a service processor and a telephone exchange therefor.
Inventor: LAUTENSCHLAGER WOLFGANG
IPC: H04Q3/62
Filed: 1994-08-13
Abstract: Prior art: A supralocal virtual private network (VPNET) is formed by a number of private branch exchanges (PBX2, PBX3) or individual sets (E10) which, if necessary, communicate via public dial-up connections. The setting-up of the dial-up connections is initiated by dialling a service (VPN). Technical problem: The entire supralocal private network (VPNET) should act like one network for callers (C) on the public network (PUBNET). Basic concept: The service supports the switching of calls both from inside and outside the private network (VPNET), but allocates different tariffing attributes to the connections. Solution: IN service which transfers both calls between private branch changes (PBX1, PBX2) of a private network (VPNET) and from outside by means of a private numbering plan but, in doing so, initiates different tariffing. Advantages:     - Uniform company call number. - The same call number when moving from the area of one private branch exchange to that of another one. - Uniform company numbering plan also valid for calls from outside.     <IMAGE>
