Title: Electronic parallel adder and subtractor BCD-8421 network - has decimal display which adds or removes numeral 6 before operations
Inventor: MERKLE PAUL
IPC: G06F7/50
Filed: 1980-10-14
Abstract: An electronic parallel adder and subtractor network operating in BCD-842-code and with a decimal display performs the addition of the base number 6 to all decades before each first addition and the subtraction of 6 before each first subtraction. The network can contain any number of decades without using additional control networks. Each decade contains only one 8421-Tetrode-Adder with no inbuilt carry difference correction and only one 8421-Tetrade-subtractor without inbuilt correction. The automatic auxiliary addition of the correction 6 is performed for each regular addition only in those decades which produce a carry to the next decade. The automatic subtraction of 6 is only performed in decades producing a carry.

Title: Packing for mass exchange column composed of corrugated strips - with offset pitch at intervals along same strip
Inventor: BAUERMANN DIETER DR
IPC: B01J19/32
Filed: 1980-12-20
Abstract: A packing for a mass exchange column consists of a number of strips having their lateral surfaces parallel to the column axis; each strip comprises ribs oriented obliquely (R1) to the column axis, while the ribs of the adjacent strips are oriented obliquely (R2) in a different direction so that the ribs of adjacent strips cross one another. Within each strip (B;B1;B2 etc.) the ribs of a certain length within the strip are offset laterally by one half of the rib spacing from the next length of the same strip. Preferably, the apertures thus formed between successive sets of ribs in the same strip are of such a size that the successive lengths of strip (B5",B5') are connected together at the points between the apertures. This arrangement improves the mixing of downward flowing liquid and ascending gas.

Patent DE-3136195-A1 (DE)
Title: Method and electrostatic dust precipitator for recovering heat and/or improving the operation of an electrostatic dust precipitator
Inventor: HERING NORBERT DR
IPC: B03C3/45
Filed: 1981-09-12
Abstract: In an electrostatic dust precipitator, the gas to be dedusted flows in virtually laminar flow past the collecting electrodes or emission electrodes through the electrostatic field and is dedusted during this period. In the metallurgical field, the temperature of the dusty gas is approximately 400 DEG C and more. Not only is the optimum ionisation temperature of the dusty gas often exceeded in the process, but the electrostatic dust precipitator is also subjected to severe thermal stress. The heat stored in the dust remains in the electrostatic dust precipitator, as the dust accretes on the collecting electrode plates. Heat recovery from the electrostatic dust precipitator is faced with a number of difficulties: the flow velocity of the dusty gas is too small to bring about heat transfer as in heat exchangers. The profiles of the collecting electrode plates, as used in electrostatic dust precipitators, were developed with dedusting in mind and are thus designed for suitable vibration by means of tapping devices. Too rapid a removal of heat in the electrostatic dust precipitator would lower the temperature of the dusty gas into the range of the acid dew-point of an acid-containing exhaust gas. To overcome these problems it is proposed that, during the same period (while dedusting is carried out in the electrostatic field) or for a longer period, a medium (26) in the aggregate state of low-temperature gas or preheated gas is passed outside the electrostatic field (14) through flow-carrying cavities (9) in which the rear sides (10a, 11a) of the collecting electrode plates (10, 11) form a boundary. The corresponding electrode precipitator is designed in such a way that the flow-carrying cavities (9) for the medium (26) are formed from collecting electrode plates (10, 11) combined in pairs, and that at least the two opposing collecting electrode plates (10, 11) which in each case are located at the end (15, 16, 17, 18) of two adjacent rows (1, 2; 3, 4; 5, 6; 7, 8) of collecting electrode plates are sealed by means of a flexible seal at the end faces. <IMAGE>
Patent DE-3142297-A1 (DE)
Title: Circuit for reducing distortion
Inventor: KAHN LEONARD RICHARD
IPC: H04H20/49
Filed: 1981-10-24
Abstract: In a circuit for generating a composite AM stereo signal, a carrier with a first signal which contains the stereo difference information, is angle-modulated and the carrier thus angle-modulated is then amplitude-modulated with a second signal containing the stereo sum information. To reduce the distortions, the distortions to be expected are determined in advance by means of a simulated transmitter and a simulated receiver and a correction signal is generated which contains signal components corresponding to the distortions. Using the correction signal thus generated, the angle modulation signal is changed by using a feedback method or a subtractive mixing method or using both methods, in order to reduce by this means the distortion in the output signal of the stereo difference channel of the actual AM stereo receiver which receives the composite AM stereo signal.
Patent DE-3144891-A1 (DE)
Title: Attachment device
Inventor: BAUS HEINZ GEORG
IPC: A47B57/34
Filed: 1981-11-12
Abstract: The invention relates to a device for attaching rack and shelving boards or the like, in particular in a mirror cabinet, adjustable attachment bodies being provided in a guide part. It has previously been necessary for inserting rack or shelving boards or the like to provide in a corresponding guide part or a wall holes or recesses, in which suitable attachment bodies could then be inserted. In order to provide a possibility of easy insertion, in this case a multiplicity of such holes or recesses were required, in which case some of them disturbed the appearance and also become soiled very easily. To solve these difficulties, the intention being to guarantee easy manufacture and reliable handling, it is proposed according to the invention that the guide part has an undercut groove, that elements are arranged in the groove so as to be displaceable in their longitudinal direction, that at least one body is provided which can be inserted in the groove between the elements, and that the elements and the body have mutually assigned surfaces which can be engaged with one another. By displacing the known elements, gaps can firstly be provided in a simple manner at the given point, in which gaps the body is then to be inserted. <IMAGE>

Title: Method for operating one or more magneto-inductive measurement probes
Inventor: MAEHLER PAUL
IPC: G01F1/60
Filed: 1982-01-27
Abstract: Such a measurement probe generates an electromagnetic field which is introduced into a moving and electrically conductive liquid, in which a voltage is induced which depends, inter alia, on its rate of flow. Said voltage is tapped using two electrodes immersed therein. It is a measure of the rate of flow. According to the invention, the electromagnetic field is generated by applying an adjustable pulse train to the winding of the probe. The open-circuit power is reduced thereby. Furthermore, the measurement can be better matched to the measurement task.

Title: Process and apparatus for recovery of the solvent in dry-cleaning machines
Inventor: BAYER GERNOT
IPC: D06F43/08
Filed: 1982-07-23
Abstract: In dry-cleaning machines having a closed circulation for the drying, recovery of the solvent from steam-containing air is initially carried out in a first step in that the solvent/steam/air mixture circulated in the drying is essentially isobarically cooled and the solvent condensing during this, with the likewise condensing water, is led off from the circulation. In a subsequent second step, the mixture is isentropically expanded, in order to further cool the rich steam/air mixture and again to condense solvent and water, which are then likewise led off from the circulation. The lean steam/air mixture obtained is then heated isobarically and further passed through the fabrics to be dried. The apparatus used therefor is provided with a circulation pipe connected to the cleaning drum, in which circulation pipe is arranged a double countercurrent heat exchanger for cooling the rich steam/air mixture and at least one expansion apparatus for expanding the cooled steam/air mixture. Condensate discharges are provided both on the heat exchanger and on the expansion apparatus.
