Patent DE-2722602-A1 (DE)
Inventor: WINTER RUDOLF
IPC: H04Q3/42
Filed: 1977-05-18
Abstract: Subscriber stations (T1, T2, Tx) with different classes of service access levels are connected to a telecommunications switching system with identifiers (R). When a call is made, the respective identification result supplies a class-of-service signal which allows only certain types of calls to be set up. Dialling cannot be performed by special subscriber stations (Tx) with the "dedicated connection" class of service access level. For these stations, the subscriber telephone number of the subscriber station (e.g. T1) which is dialled automatically on loop closure in the special subscriber station (R) is stored in the identifier (R). A special subscriber class-of-service signal obtained simultaneously with the abovementioned subscriber telephone number on identification of a special subscriber station (Tx) effects the transmission of the identified subscriber telephone number to a trunk circuit (L1) located in the connection path which is being set up. <IMAGE>

Title: Sliding mould for electroslag remelting plants - where tubular copper mould is free to expand in steel water cooling jacket
Inventor: HOLZGRUBER WOLFGANG DIPL ING D
IPC: B22D23/10
Filed: 1977-06-02
Abstract: Liq.-cooled sliding mould esp. for electroslag remelting plants, using at least one copper insert in a steel jacket. The insert consists of a thin walled Cu tube provided on its outside dia. with equispaced reinforcing ribs extending radially outwards; the vertical ribs end in a flange located at both ends of the Cu tube. The bottom flange is fixed to the steel jacket and provides an inlet for the coolant; but the top flange is free to move axially inside a steel flange on the jacket to permit the Cu tube (i.e. the mould) to slide axially when thermal expansion or contraction occurs. The Cu tube pref. has a wall thickness of max. 25 mm for tube dias. up to 1500 mm; and the vertical ribs pref. have a rectangular cross-section with thickness max. half the tube thickness. Used on modern electroslag remelting plants, using a short mould with height e.g. 700-900 mm. The relatively thin wall of the Cu tube forming the mould permits good heat transfer to the cooling water; but mould distortion is avoided. The overall result is a mould with low mfg. costs but long working life.

Patent DE-2846012-A1 (DE)
Title: Container fluid level measurement - by extracting some contents at free surface level and discriminating liquid from gas or froth
Inventor: LODES RAINER
IPC: G01F23/00
Filed: 1978-10-23
Abstract: The liq. level in containers with a liq. which tends to gum up a float or is difficult to measure by conventional means because of high internal pressure or aggressiveness can be established by extracting some of the contents at the desired level in the container. The appearance of liq. proves that the level is higher, that of gas that it is lower than desired and the appearance of froth that the level is right. The extracted liq. can be collected in a bucket and returned to the container by a pump. If a closed circuit is used, the discrimination between liqs., gas and froth is made by a flow meter. Alternatively, heat can be applied at the start of the circuit and the difference in the specific heat or thermal conduction can be used for this discrimination. Such a system is universally applicable and requires less capital cost than radio isotope or ultrasonic methods of fluid level detection.
