Patent DE-2902897-A1 (DE)
Title: Telephone exchange transmission system - has bucket chain analog registers for signal compression and expansion in pairs corresponding to each signal source
Inventor: KARLSTETTER DIETER DIPL ING
IPC: H04J3/18
Filed: 1979-01-25
Abstract: A communications system transmits analogue signals over a transmission line with time multiplex processing, employing time compression at the outgoing station and time expansion at the incoming one. Each analogue signal is stored in turn in one of two allocated analogue registers for compression and expansion. The signals pass in the same direction through the transmission line (Lab). Each of the two signal sources (As, Bs) has a pair of analogue registers (Sa1, Sa2, Sb1, Sb2, Ea1, Ea2, Eb1, EB2) at both ends of the line. They are designed as bucket chain registers with a number of steps and shift cycle large enough to produce only sligh shape deviations in the stored signal trains. A low-pass filter (TPab) at the transmission end of the line limits the pass band to the sum of the frequency bands of the original system. The resulting system can be applied to transmission lines used also for other purposes with a maximum of economy in equipment.

Title: Welding of tubes in tube plates for heat exchangers - using bushes and TIG welds to minimise heating of tubes or plates so their corrosion resistance is not impaired
Inventor: DIEKMANN HELMUT DIPL ING
IPC: B23K9/028
Filed: 1980-06-04
Abstract: Both the tubes and the tube plates form pptes. when heated in a critical range; and such pptn. markedly reduces their corrosion resistance. To avoid this problem, a bush is first welded or rolled into each hole in the plate. Both ends of the bush project beyond each side of the plate. The bushes are made of the same material as the plate, or of a purer or more highly alloyed material, and possess a slightly larger bore dia. than the external dia. of the tubes. The plate contg. the bushes is heat treated; and then a tube is welded in each bush using the min. amt. of heat. Useful e.g. with highly alloyed stainless steels or Zr, so their corrosion resistance is not impaired by heat arising from a welding process.

Title: Double rotary suspension filter drums with endless belts - lifted from surfaces in cake removal area
Inventor: HEINTGES SIEGFRIED DIPL ING
IPC: B01D33/00
Filed: 1980-09-11
Abstract: Double drum vacuum filter for removing suspended solids from slurries has two large drums horizontally rotating side by side in close proximity and each perimetrally engaged by an endless filter belt, with these belts in contact between the drums. Slurry is fed into the double-curved space between the tops of the drums and in the high-suction outer area of the drums a layer of solids builds up on the belts. Near the lowest points of the drums both belts are lifted from the drum surface over deflector rolls. In this area the suction is reduced and the adherent cakes can be stripped from the belts, which are then sprayed clean by water jets before returning into contact with the drums. Used in the mineral industries, e.g. for flotation concentrates and coal slurries. The filter unit operates continuously, with low leakage rate, while the cakes are effectively removed without damage to the belts.
Patent DE-3037379-A1 (DE)
Title: Steam iron with anti-furring device - comprising bimetallic disc which changes form on cooling to break loose deposited solids
Inventor: CONRAD RAINER DIPL ING DR
IPC: D06F75/18
Filed: 1980-10-03
Abstract: A domestic steam iron has a bimetallic disc in the steam chamber beneath the water inlet valve which has an upwardly convex shape at room temp. At a temp. somewhat below the working temp. of the iron, the disc snaps into a concave shape and receives the water dropping through the valve. The water evaporates from the disc, depositing thereon any dissolved solids, which are subsequently broken loose as the disc reverts to its convex shape when the iron cools down after use, enabling the deposits to be easily removed. This prevents blockages caused by the gradual accumulation of hard-water deposits.

Title: Method and device for measuring heat consumption
Inventor: KNAUER DIETER
IPC: G01K17/06
Filed: 1981-02-16
Abstract: The invention relates to a method and a device for measuring heat consumption, e.g. heaters of central heating installations. The measurement of the heat consumption is performed in this case by instituting the storage and display operation only upon achievement of a prescribed settable switching-on threshold temperature and interrupting it upon achievement of a specific switching-off threshold temperature, and by counting the duration of the on-time from the start of the institution of the storage and display operation, taking the counting pulses over into the memory and displaying them when summed up (see Fig. 2). At the same time, the frequency of the counting pulses is varied during the on-time as a function of temperature, in particular increased with rising temperature. This guarantees a very accurate measurement of heat consumption in conjunction with minimum outlay. <IMAGE>
