Patent DE-3101565-A1 (DE)
Title: Process for producing a casting mould
Inventor: SCHNEIDER WERNER
IPC: B22C23/02
Filed: 1981-01-20
Abstract: A new process is specified for applying a fireproof coating onto the plastics which are used in the vacuum moulding process or full mould casting process and can be gasified substantially without residue during casting. This material, designated slip, has hitherto been mixed with a liquid solvent and sprayed on. However, the solvent has a long drying time which unnecessarily extends the cycle time. If the solvent is not allowed to dry entirely, casting defects may occur during casting due to the formation of vapour bubbles. According to the invention the fireproof material is intended to be sprayed on in the dry state, preferably in an electrostatic field.

Title: Broadband switching system
Inventor: BARABAS UDO DR ING
IPC: H04Q11/04
Filed: 1981-03-12
Abstract: In a broadband communications system whose subscriber lines are preferably formed by optical waveguides, via which TV broadband signals are transmitted as pulse-modulated signals, each TV programme (P1) is fed for TV programme distribution in a plurality of time slots to programme-specific inputs (e11...e14) on time slot-specific switching levels (ZE1) of a broadband switching arrangement whose switching point switches (11kt...p4kt) are provided on the output side with emitter follower circuits. When the actual power switches of the switching point switches (...p1kt) are in the blocking condition, their emitter follower circuits are also blocked, in order to increase the stop-band attenuation and suppress crosstalk, by a time-modulated (PPM-)signal pulse through-connected via a closed switching point switch (11kt); when the switching point switch (p1kt) is blocked, the broadband signal concerned is then subjected to the cascaded stop-band attenuation of the power switch and emitter follower. The switching point switches and threshold value multiplex circuits are preferably formed by logic elements implemented using ECL technology. <IMAGE>

Title: Device in railway systems for backed-up long-distance transmission of binary data words
Inventor: MUECKE SIEGFRIED ING GRAD
IPC: H04L1/08
Filed: 1981-04-29
Abstract: For backed-up long-distance transmission of binary data words in railway systems, the binary signals of a data source (DE) are transmitted serially in the form of modulated AC signals via any given data channel (DL) to a receiving station. The data telegrams of the same information are duplicated for back-up purposes. The binary signals of one of the two data telegrams are inverted at pre-defined bit positions. This marking serves as an address for the respective receiving station. The marked data telegram is decoded once more in this station and fed along with the unchanged second data telegram to a back-up comparator (VG) which transmits information only when the fed-in signals reveal correspondence. <IMAGE>

Patent DE-3139632-A1 (DE)
Title: Stove insert for a tiled stove
Inventor: MEDITZ THEOBALD
IPC: F24C1/14
Filed: 1981-10-06
Abstract: The invention describes a stove insert, in particular for a tiled stove, which comprises a combustion chamber, from which the smoke gases are conveyed via a heat exchanger to a take-off, with suction openings in the region of the combustion chamber for fresh air which is heated on the combustion chamber and, according to the principle of gravitational force, passes along the heat exchanger, undergoing further heating, to upper stove outlet openings. According to the invention, it is envisaged that regions of the heat exchanger are arranged in the flow path of the fresh air, in which regions there are provided air passage cross-sections which are narrow in relation to the suction opening cross-sections. As a result, high air passage rates are created in the region of the heat exchanger, which has the result that the fresh air which is preheated on the combustion chamber is effectively heated in the heat exchanger and that, as a result of the suction thus created, great quantities of fresh air are drawn in so that overall great quantities of warm air can be obtained, which make possible better utilisation of the energy released during combustion than is possible with known stove inserts.

Patent DE-3244052-A1 (DE)
Title: Ship for the transport of liquids and gases under pressure
Inventor: MEYER BERNARD
IPC: B63B25/14
Filed: 1982-11-27
Abstract: A tank with several chambers lying side-by-side, instead of the known twin-chamber pressure tank, is proposed for the transport of pressurised liquids and gases, which chambers are again derived from the cylinder form and are subdivided by vertical bulkheads. This results in favourable bulkheading in the event of accidents, the possibility of better weight distribution for the transverse stability, and a cross-sectional shape of the tank which permits increases in volume over the cross-section of the ship without the draught of the ship increasing. Supporting of the pressure tanks is possible via longitudinal members, which support the tank as extensions of the longitudinal bulkheads.
