Title: Holder for mounting plate in housing for electrical installations
Inventor: KORHONEN OLLI
IPC: H02G3/14
Filed: 1998-04-07
Abstract: A holder for mounting a plate (7) like a front plate, a plate to protect against contact or a circuit board inside a housing for electrical installations is described. The housing has a lower part and the holder (5) is formed  from an elongated element which has a main part (8) and a hole (17,18) at least at one end for fastening the holder to the lower part. At least at one end of the holder is located an extendable wedge section (9,10) which can extend against the lower part if a fastening device (19,20) is fastened in a hole at the end of the holder. Through this, a bearing surface which is designed on the wedge section is supposed to press against the wall of the lower part in order to fasten the holder by friction force at a desired height from the bottom of the lower part of the housing. The wedge section is located so that it can be adjusted in a direction in which the length of the holder is increased. Between the wedge section and the main part of the holder, a slit (11,12) is provided to effect a material weakening in the holder. This grants flexibility to the combination of main part and wedge section, through which the adjustment of the wedge section is possible.

Title: Routing method for packet switched communication network
Inventor: NIMPHIUS KLAUS
IPC: H04M3/00

Abstract: The method involves supporting the signalling protocol (CCSN7) for an interworking with a subscriber data base (HLR) of a mobile radio network (PLMN) by a network unit (GAW,GAK) of the packet switched communication network (IPN). A request is made from the network unit from the packet switched network to the subscriber data base of the mobile radio networks using the signalling protocol, if the routing of the connection is carried out in the packet switched network or in the mobile radio network.  Preferably, a response is sent from the subscriber data base by sending back at least one information to the packet switched communication network with which the communication unit decides that the routing is carried out in the packet switched network.

Title: Method and apparatus for determining the length of an electrode
Inventor: TRICARICO CLAUDIO
IPC: G01B7/02
Filed: 1998-09-04
Abstract: The electrode measurement apparatus includes a movably mounted contact element (2) which has at least one surface for making a mechanical and electrical contact with the electrode whose length is to be determined.  This contact element is kept apart from a contact element (5) using a spring whose resisting force can be overcome by an externally applied force. The electrode (1) is brought in touch with a contact element (2) and is advanced further in the same direction until the contact element (2) touches the contact electrode (5) and produce a short circuit.  Since the position of the contact electrode (5) is known, the position of the free end of the electrode (1) can also be established.  The protruding length of the electrode (1) is determined as the difference between the position of its free end and position of the electrode holder.  The apparatus includes a movably mounted contact element (2) which has at least one surface for making a mechanical and electrical contact with the electrode whose length is to be determined.  This contact element is kept apart from a contact element (5) using a spring whose resisting force can be overcome by an externally applied force.
