Patent DE-2548715-A1 (DE)
Title: Heat transport for district heating - is achieved by movement of ammonia and salt which have thermal reaction
Inventor: ALEFELD GEORG PROF DR
IPC: F28D20/00
Filed: 1975-10-31
Abstract: A calcium salt of ammonia is heated at a pressure between 15 and 50 bar by the exhaust steam of a power station. The ammonia is given off from the salt and is allowed to liquefy by natural atmospheric cooling. The liquid ammonia and the salt are loaded in tanks and transported by ship or rail to the consumer station. At the consumer station the ammonia is evaporated by heat drawn from the atmosphere or a river and the vapour is recombined with the salt. This process gives out heat which is used for raisig low pressure hot water to temperatures between 80 deg. and 90 deg.C. The process is cheaper than distribution by pipelines for distances up to 100 km.

Title: Contact plate for gas-liquid contact columns - e.g. for rectification, absorption, washing, esp. with thermally sensitive materials
Inventor: SLOBODJANIK IWAN PETROWITSCH
IPC: B01D3/22
Filed: 1975-12-05
Abstract: The plate consists of a perforated circular disc. The perforations are in the form of slots which have domed covers. Gas passes upwards through the slots and is compelled by the covers to flow tangentially and at an angle to the surface of the disc in one direction. The side of the disc on which the liq. is carried is provided with baffle plates in the form of Archimedean spirals diverging from one another from the centre of the plate. The baffles cause the liq. to flow in the same direction as the gas leaving the slots. Exceptionally uniform liq distribution is achieved over a wide range of operating conditions. The system is particularly advantageous for large dia. columns where bad distribution and wave formation are often encountered.

Title: Induction motors with improved starting characteristic - has inductances with large laminated cores to provide attenuation of higher harmonics during start-up
Inventor: BOECKH JOHANN VON DIPL ING
IPC: H02P1/28

Towards the end of the start-up cycle the relay is activated to short circuit the inductances.
Patent DE-2613868-A1 (DE)
Inventor: GEHRIG HANS-RUDOLF
IPC: H04M15/10
Filed: 1976-03-31
Abstract: In time pulse counting, the time parameter is linked with the distance and in each case corresponds to the time period during which the subscriber may talk for one charge unit. To generate the time counting pulse strings, devices are provided which are in each case able to transmit a pulse string at a frequency which corresponds to the charge zone derived from the telephone number of a called subscriber. The present arrangement is designed for any number of charge zones and enables a charge-zone-individual changeover from one tariff to another which affects existing connections. The time counting pulses supplied by a clock generator (TE) for the individual charge zones are read into buffer memories (ZS) assigned to the charge zones, are then read out at time intervals allocated to each charge zone, staggered in time and forwarded via an individual line (L) to evaluation devices (AW) assigned to established call connections. <IMAGE>
