Title: Data telephone set esp. magnetic card operated appts. - sends data via telephone and data lines using switches connected to lines and to voice circuit and to input magnetic card reader or similar
Inventor: MEYER ANDREAS
IPC: H04M11/06
Filed: 1989-07-28
Abstract: The data telephone set has a magnetic-card reader (or other input device) to send card data via the telephone line.  The data input device can be connected via a modem to the telephone line. A first switch breaks the connection between voice circuit and telephone line.  A second switch breaks the connection between data input device (= reader) and a line used exclusively for data transmission. The modem lies in the connection between the data input device and the telephone line.  This connection is actuated when the two switches are opened by means of a switching element, itself actuated via a connection to the data input device. ADVANTAGE - Data can be sent via both telephone and data lines.
Patent DE-3929181-A1 (DE)
Inventor: ZERVER HERMANN-JOCHEN
IPC: B21J5/02
Filed: 1989-09-02
Abstract: The invention relates to a procedure for making workpieces embossed or forged in a die, in which, after embossing or forging, the blank (2) has the flash removed and is subjected to machining, at least on those faces which are important for the functioning of the workpiece, and to heat treatment to alter its structure. In order to permit more rapid and more economical production of the workpieces while eliminating some of the machining operations, a path-controlled laser is used for removing the flash from the embossed or forged workpiece blank (2). The flash removal operation preferably takes place after the heat treatment of the blank with the flash still attached, the laser producing the functional surfaces of the workpiece blank in the same operation. <IMAGE>

Title: Cold-rolled metal strip of required hardness prodn. - involves forming rough strip and then rolling it to finished form with predetermined nominal thickness
Inventor: KOETHEMANN KARL HEINZ DR ING
IPC: B21B1/28
Filed: 1990-05-16
Abstract: Prodn. of cold rolled strip made from non-ferrous or ferrous metals or their alloys, involves the prodn. of a rough strip in a roller stand having a wider rolling thickness finishing tolerance than that of the finishing roller. A rough strip is produced with a rolling thickness between an upper boundary value (DO) and a lower value (DU). The upper value (DU) is selected so that the prescribed max. hardness and strength of the finished strip is adhered to on the basis of strength values determined for such a degree of deformation when the rough strip is converted into the finished strip with a rough thickness (DO) corresponding to the upper boundary value. The finished strip thickness corresponds to the nominal thickness reduced by the rolling thickness finishing tolerance of the finishing roller stand.  In a similar way, the lower boundary value is determined.

Patent DE-4118793-A1 (DE)
Inventor: PFAENDLER MARTIN
IPC: G01F23/22
Filed: 1991-06-07
Abstract: The device has at least two vibration rods secured at a distance apart to a diaphragm, the edge of which is connected to a screw-in member. A clamping screw is secured to the diaphragm on the side away from the clamping rods tightly enough for the clamping screw and the diaphragm to adopt a position in which the axes of symmetry coincide. The clamping screw is surrounded by a stack of annular piezoelectric elements, electrodes and insulating rings. The stack forms the excitation and reception converter of the device. The stacked excitation and reception converter is clamped and secured between the diaphragm and a hexagon nut. The stack is supported by means of the terminating metal ring on a shoulder surrounding the diaphragm and positioned at a distance from it. The clamping force is selected so that the diaphragm is prestressed to a concave shape at the same time. The excitation converter excites the vibration rods to vibrate at their natural resonant frequency transversely to their longitudinal axes. The reception converter detects a change in the vibration behaviour of the vibration rods and use is made of this to determine and/or monitor the predetermined level. The change in both the vibration frequency and vibration amplitude of the vibration rods may be taken into account.
