Title: Method and circuit arrangement for automatic dialling of destination subscriber telephone number parts in a centrally controlled communications PBX system
Inventor: WILLE KLAUS
IPC: H04M3/44
Filed: 1985-09-06
Abstract: Subscriber stations (EG1...EGn), such as telephone, telex, fax and videotex subscriber stations, which are associated with different communications services are connected to the centrally controlled communications PBX system (KNST). Connections can be set up from the subscriber stations of at least one communications service to external destination subscribers to whom matching service-specific telephone number parts are allocated. Once a code has been dialled to set up a connection from a subscriber station (EG1...EGn) to an external subscriber, the central controller (ZST) identifies the communications service type of the subscriber station setting up the connection by retrieving service-specific identification information from first memories (ISP1...ISPn) which are connected to the subscriber connection circuits (TS1...TSn) allocated to the subscriber stations (EG1...EGn). The central controller (ZST) automatically dials the associated fixed service-specific telephone number part and then releases the dialling of a telephone number part, which may need to be supplemented further, to the subscriber station setting up the connection. <IMAGE>

Title: Apparatus for destruction of urinary tract concrements
Inventor: SCHMIDT-KLOIBER HEINZ DR
IPC: A61B18/26
Filed: 1986-01-13
Abstract: At the emergence end of a flexible light guide serving to convey short-term, highly energetic laser pulses there is arranged a hollow light funnel which has a reflecting inner surface in the form of a truncated cone and whose larger entry surface facing the light guide outlet is larger than or identical to the emergence cross-section of the light guide. Despite a relatively low energy or power density inside the light guide it is nevertheless possible to achieve a field strength that is sufficient for a break-through at a safe distance from the emergence surface of the light guide, and this results in a simple, reliable arrangement which is suitable, in particular, for the destruction of concrements in the region of the human ureter.

Title: Mounting device on a machine tool
Inventor: KAESTNER ROLF DIPL ING
IPC: B23Q3/12
Filed: 1986-06-28
Abstract: The invention relates to a mounting device on a machine tool for clamping and/or releasing an add-on auxiliary device, e.g. of an angular milling head, for the purpose of providing a temporary driving connection with the work spindle of the machine tool. The object of the invention is to provide a simple mounting device for clamping/releasing add-on auxiliary devices even in the case of relatively large units. The essence of the invention is that said mounting device has no structural elements which encase the work spindle/spindle nose of the machine tool and thus clamp the add-on auxiliary device in an axially centring fashion, but which is in principle afforded a precise centring of the drive axis of the units relative to the work spindle axis and reliable holding as well as clamping/releasing of the add-on auxiliary devices. In a development and modification according to the invention, the solution is based on devices for automatically clamping and releasing tool holders in/from a machine tool work spindle with the aid of a tie-bolt, to which force can potentially be applied by disc springs and which is connected to a set of clamping segmental hooks which engage from behind and hold securely one of the tightening bolts which are mounted in a multiple arrangement in the add-on auxiliary device which is to be clamped. <IMAGE>
