Patent DE-4018382-A1 (DE)
Inventor: SCHEERER ULRICH
IPC: H04Q3/62
Filed: 1990-06-08
Abstract: 2.1 The use of speech paths for data links in communication exchanges is to be largely avoided when dialling units of simple telephone terminals are used for data input. Uniform input formats are to be made available to the data terminal devices, independent of the design of the input units (dial switch, keypad) of simple telephone terminals. 2.2 The information transmitted by an analog terminal and received by a relevant local controller is forwarded via an existing bus line system in a signalling channel formed for this purpose to a centrally disposed processing unit provided to perform specific tasks. The processing unit checks the data arriving from the analog terminal and forwards them only if they can be processed correctly therein. A forwarding signalling channel connecting to a data terminal device is formed. The processing device informs the analog terminal whether the data transmission has been performed correctly or not. 2.3 No speech path needs to be made available in order to set up a connection between a simple analog telephone terminal used to input data and a data terminal device. The dialling-information receiving devices already present in the local control devices can be used at no additional cost to receive the information transmitted from the subscriber terminals. There is therefore simply a link via the signalling paths, which is activated for a short period on each individual data input. The processing device furthermore enables uniform data formats to be transmitted to the data terminal devices, independently of the type of the respective telephone terminal used for data input. Furthermore, the processing unit can cause audible tones and/or spoken announcements to be transmitted to the calling telephone terminal. <IMAGE>

Title: Filter cartridge removing dust particles from gas in restricted space -  has elongated filter tube open at unsupported end and reaching into filter basket with reducing tube dia.
Inventor: HUETTLIN HERBERT
IPC: B01D46/02

Title: Removing hardness forming and heavy metal ions from water - by treatment with strong acid cation exchanger in sodium form followed by reverse osmosis
Inventor: WANDELT ERWIN
IPC: B01J39/05
Filed: 1990-09-29
Abstract: Process for treating liqs., esp. water, in ion exchangers which for the removal of the hardness-forming ions Ca, Mg, Sr and Ba and all heavy metals are connected in series with a further processing stage of reverse osmosis, whereby a strong acid cation exchanger is used which is converted into the Na form by treatment with acid and then with the effluent water stream from the downstream reverse osmosis process. USE/ADVANTAGE - The process allows hardness forming ions to be removed from the water so that no deposits are formed on the reverse osmosis membrane without the necessity for adding stabilising chemicals to the water, whilst regeneration of the ion exchanger is accomplished without producing an effluent water contg. large amts. of NaCo, which could cause a disposal problem with large scale appts..

Inventor: KRAEWER HANS-PETER
IPC: G01M3/28
Filed: 1991-08-16
Abstract: In a known apparatus, a pressure display device must be observed and a timing device must be started simultaneously when measurement begins, which often leads to incorrect measurements. The apparatus consists of a pressure cylinder (1), a piston (2), a piston rod (4) and a pressure display device (9), indicated a loss of pressure in the gas conduit (12) which has been indicated by the pressure display device (9) being compensated for by displacement of the piston (2), and the leaked amount being indicated by means of a scale (15) against which the position of the piston (2) can be measured. As a further development of this apparatus, it is proposed that, once measurement has started, a timing device (16) be automatically actuated by means of a ball (19) loaded by a spring (18) when a zero position is passed through. <IMAGE>

Patent DE-4132508-A1 (DE)
Inventor: REIME GERD
IPC: H04N9/64
Filed: 1991-09-30
Abstract: At the location in a colour channel (2) at which a colour signal (Fe) is transmitted and a colour interference area forming a colour fringe with wrong colours exists at colour discontinuities, the colour channel (2) is split into a delayed channel section (10) and an undelayed channel section (11) and the outputs of these channel sections are connected via a channel switch (12) to the output (3) or to the continuation of the colour channel. The delayed channel section contains a delay line (13) having a delay time (TK) which is greater than the width of the colour interference locations in time. At a colour interference area detected by a colour discontinuity detector (15), the channel switch is switched over during a predetermined switching time (TS) in such a manner that it transmits, instead of the disturbed area of the delayed colour signal in the delayed channel section of the colour channel, an undisturbed area of the undelayed colour signal from the undelayed channel section. In the case of an additional luminance discontinuity, a luminance discontinuity detector (22) controls the control circuit for the channel switch (12) instead of the colour discontinuity detector. This reestablishes undisturbed colour discontinuities in the transmitted colour signal. <IMAGE>

Patent DE-4136779-A1 (DE)
Inventor: BRADEN CHRISTOPH DIPL PHYS DR
IPC: G01N27/49
Filed: 1991-11-08
Abstract: The apparatus for the simultaneous determination of different gas components comprises a multiplicity of electrochemical three-electrode measuring cells with a common electrolyte which are formed by a multiplicity of working electrodes with a common counter-electrode and a common reference electrode. The measured value is produced with the aid of a potentiostatic analysis circuit which also adjusts and defines the potentials at the working electrodes. The current signals correlated with the gas concentrations to be measured are indicated with the aid of ammeters 111..11n in the lines to the working electrodes 51..5n. In doing so, it is essential that all the three-electrode measuring cells have a common counter-electrode 3 and a common reference electrode 4 and that the potentiostatic analysis circuit 6 has control circuits 71..7n which keep the potentials of the working electrodes 51..5n relative to the reference electrode 4 constant, individually and independently of one another.
