Title: Data communications system connecting telex and teletext stations - stores all message signals and call numbers in RAM belonging to loop device having separate control, connected only during transmission
Inventor: HAGEN ROLF DIPL ING
IPC: H04L12/18
Filed: 1979-03-30
Abstract: The data communications system stores all the message signals and all call numbers sent from the transmitting station via the data switching exchange in a random-access memory belonging to a loop device containing a separate control. This control is only connected to the data switching exchange for the duration of the transmission of the message signals and call numbers. The message signals stored in the loop device's memory are sequentially transmitted (under the control of the control belonging to the loop device) via a connection (set up only for the duration of message signal transmission) to the receiving station described by the stored call number.

Title: Increasing the hydrocarbon content of coke-oven gas - by adding active nickel to coking coal
Inventor: SCHMITT HUBERT DR
IPC: C10B57/06
Filed: 1979-04-09
Abstract: The aliphatic hydrocarbon (esp. CH4) content of coke-oven gas is increased by mixing the finely divided coking coal with finely divided catalytically active Ni and coking the mixt. The Ni is pref. added in an amt. of 0.1-2.5 wt.%. It can be produced by decomposing a Ni salt and reducing the resulting oxide. In a specifically claimed process, the coke is gasified, the Ni is recovered from the gasifier slag and reconverted to catalytically active form for recycle to the coking coal, the coke-oven gas is cooled, cleaned and sepd. into H2, CO and CH4, the H2 and CO are methanated together with the product gas from the gasifier, and the resulting CH4 is combined with the CH4 from the sepn. unit. The process gives significant (e.g. 25%) increases in CH4 prodn. at high coking temps. (900-1400 degrees C).

Title: Tree trunk cutting machine - has tool holders mounted on rotor and has motors balancing cutters on two armed levers
Inventor: BRAUN PETER ALEXANDER
IPC: B27C5/08
Filed: 1979-05-21
Abstract: An annular rotor, surrounding the trunk, has holders running round it with cutting tools for setting against the trunk, on a machine for reducing trunk timber. The tool holders (5) are in the form of two-armed levers, (11) mounted on the rotor (4). The tool holders each have a cutter (7) at one end, and an esp. electric motor (12) at the other end, to drive the cutter. The arrangement is such as to produce a static weight equalisation between motor and cutter. Driving pulleys (13) and driving-belts (14) may provide connection between motor and cutter. This prevents the weight of tools and tool holders from influencing application force during rotor revolution.

Title: Motor for driving reciprocating shaft - is positioned coaxial with rotor shaft and driven by oscillating disc and bearing
Inventor: ROSER ERICH
IPC: F04B43/02
Filed: 1979-11-06

Title: Electronic thrombocyte counter - operates on coulter principle and uses difference of successive cell counts
Inventor: DIEDERICH GEORG
IPC: G01N15/12
Filed: 1980-03-03
Abstract: The number of counters operate on the Coulter principle with a single discontinuously or continuously adjustable lower threshold value. The total number of all suspended blood cells is initially counted, by using a threshold value corresponding to the smallest thrombocytes, with all blood cells except the thrombocytes then counted, by using a threshold value corresponding to that just above the largest possible thrombocytes. The number of thrombocytes per unit vol. is obtained from the difference of these two counts, after compensating for the different amounts of the fluid suspension corresp. to the two threshold values.

Patent DE-3017685-A1 (DE)
Inventor: HERKLOTZ HELMUT DIPL ING
IPC: B03C3/68
Filed: 1980-05-08
Abstract: A system for controlling the voltage of an electrofilter of the type which, after a voltage breakdown, substantially reduces the magnitude of the electrofilter voltage. After a predetermined deionization time, the filter voltage is raised to a new level which is lower than the filter voltage at which the initial voltage breakdown occurred, by a predetermined amount. The filter voltage is subsequently raised in accordance with a predetermined voltage-time function until a further voltage breakdown occurs. The electrofilter voltage is controlled by a microcomputer system in accordance with stored control parameter values. The stored control parameter values are advantageously recalled to control the electrofilter voltage in response to the operating state of a plant in which the electrofilter is employed. In plants wherein a plurality of electrofilters are employed, each such electrofilter is controlled by an associated microcomputer system, the plural microcomputer systems being controlled by a central pilot computer. The central pilot computer of the plant computes strategies which enhance the energy efficiency of the overall electrofilter purification system.

Title: Sensing distance to surface - using pulse modulators for EM carrier wave and supplying acoustic generator
Inventor: BECK MAURICE SIDNEY
IPC: G01F23/22
Filed: 1980-08-19
Abstract: An acoustic radiation is generated to measure the distance to a surface which can be uneven due to turbulence, waves on a liq. surface, a stoney surface etc. A device is provided to generate an electro-magnetic carrier wave. Modulators ensure that a portion of the pulses of the carrier wave radiation is of different duration from the other portions. The modulated carrier wave is fed to an acoustic generator so that an acoustic radiation with a varying polarisation pattern is produced. The modulators can be designed to produce a pseudo-random binary series. The carrier wave can be subjected to amplitude modulation with a modulation depth of 100% so that the acoustic radiation can be produced in the form of a pseudo-random series at a base frequency. The carrier wave can be subjected to frequency modulation so that a continuous acoustic radiation can be generated at two alternating base frequencies.
