Patent DE-2415250-A1 (DE)
Title: Transmission of characters via telecommunications system - suitable for transmission of pictures, facsimiles, or writing
Inventor: CAMEN DIETER
IPC: G08C21/00
Filed: 1974-03-29
Abstract: The proposed equipment makes use of the principle of equipotential lines between electrodes and may be used over telephone systems without using extra lines. The transmitting and receiving ends both have a conducting rectangular plane, e.g. conducting surface paper, with 6V. electrodes in their upper corners and the OV electrode in the middle at the bottom. These electrode pairs are fed from different frequency generators and result in a pattern of equipotential lines across the surface of the plane. The plane may thus transmit positional information on a conducting pen on its surface by the mixed frequency signal relative to teh OV electrode. This may then be transmitted over a telephone line in the same way as speech to the receiving end.

Title: Controlled operation of sulphur recovery plant - esp. on start-up and shut-down
Inventor: THOMSEN ADOLF
IPC: C01B17/04
Filed: 1975-01-15
Abstract: In a method for improving the operation of sulphur-recovery plants (e.g. Claus Plante) esp. during start up and shut down, a controllable quantity of heating gas is passed through the catalyst layers in order to prevent or control local overheating of the catalyst by spontaneous oxidation of sulphur remaining in the bed. Heating gas generated by fuel firing using large quantities of excess air (which simplify heater operation) can be used without requirement for expensive control equipment, when by pass in open, excess oxygen flow through catalyst is prevented. The by-pass can then be closed slowly over a period of hours. Process can be constantly supervised by operators, the life of the catalyst is thereby increased, and the operating temp. of the catalyst under normal conditions can in fact be controlled using the by-pass.
