Title: Telephone wire teleprinter system - encodes each signal by combination of upper and lower voltage thresholds and voltage polarities
Inventor: DIRR JOSEF ING GRAD
IPC: H04Q1/40
Filed: 1979-10-30
Abstract: Counters are provided for the transmission of subscriber dialling signals as well as teleprinter signals over telephone lines with the aim of simplifying the circuitry usually required for shaping the inductively-distorted pulses. During transmission the counters work synchronously so that during reception positive pulses are received via the a and b lines over either of two contacts. If twelve dialling buttons are used, buttons one to six energize a relay for one contact and buttons seven to twelve energize a relay for another contact. The opto-electronic couplers apply count pulses to the counter in accordance with pulses generated at the central Exchange. The timing of a relay operation also determines when a contact interrupts the line and defines the selected button. For teleprinter purposes, half-duplex operation can be arranged by allotting one d.c. polarity to each direction of transmission.

Patent DE-3005550-A1 (DE)
Inventor: HOFSTADT CARL-ERNST DIPL CHEM
IPC: B01J21/04
Filed: 1980-02-14
Abstract: A process for the production of olefins from synthesis gas comprises a first synthesis stage in which a mixture of methanol and higher alcohols are formed from a synthesis gas comprising hydrogen and carbon monoxide. The catalyst for the first synthesis stage comprises the oxides of copper and zinc in intimate association with each other and a promoting compound selected from the group consisting of chromium, cerium, lanthanum, manganese, thorium, and an alkali metal. The materials from the first synthesis stage are separated into a gas phase and a liquid phase. Thereafter the methanol is separated from the higher alcohol fractions. The higher alcohols are then subjected to dehydration in a dehydration stage which comprises passing the higher alcohol fraction over an alkalized dehydration catalyst at a pressure in the range of 0.5-1 bar and a temperature in the range of 350 DEG -500 DEG  C. Thereafter the olefins produced by the dehydration of the higher alcohols are separated into the olefinic and non-olefinic materials. Preferred dehydration catalysts include alkalized aluminum oxide and alkalized calcium phosphate.

Title: Coil winding assembly for instrument transformer - comprising sub-assemblies of unit turns arranged to give closely spaced tappings
Inventor: AUER WILLI DIPL ING
IPC: H01F29/02
Filed: 1980-03-13
Abstract: The object of the coil assembly is to give closely spaced tapping points without requiring unused windings at any point. The complete coil is made up using a basic subassembly or subcoil (c) with a fixed number of turns. These subcoils are connected together to form other winding parts; a main coil (a) consisting of z subcoils in series, where Z=1, 2, 3..., and part coils (b) of m subcoils, with M=O, 1, 2,.. The complete winding comprises one subcoil (c) on one side of the main coil (a), and several part coils (b) on the other side. The sum of the subcoils in the part coils is always one less than the number of subcoils in the main coil. Tapping points are provided at each sub, part and main coil connection. By careful choice of turns on the subcoil, the tapping points can progress in very small discrete steps. Arrangements with two separate coil assemblies on this principle can be interconnected with jumpers to get the required tappings.

IPC: B01D53/86
Filed: 1980-05-05
Abstract: A method of reducing the discharge of harmful gaseous and/or dusty substances in flue gases or other gas discharges from industrial plants or furnaces by hot-recycling and condensation- sorption is claimed. Pref. the process is carried out to reduce the SO2 content in the gas by passing it through a catalytic converter consisting of a platinum-asbestos or vanadium pentoxide grating, plates, pipes, or ducts, in order to convert the sulphur dioxide into sulphur trioxide and then, in the presence of water vapour, into H2SO4. The catalytic converter is pref. heated to the most effective surface temp. The flue gas or waste air cooler is pref. regulated to provide a discharge temperature of approx. 0 deg.C. Between the catalytic converter and the cooling unit, water, water vapour or steam, alkaline or acidic chemical substances may be continuously added in order to increase, reduce, acidify or neutralize the condensate. Process improves the quality of discharges to atmosphere from industrial plants and furnaces.

Title: Dust filter made from thin plastics or metal foil - with numerous small perforations to promote retention of fine particles
Inventor: WEBER EKKEHARD PROF DR ING
IPC: B01D45/08
Filed: 1980-07-03
Abstract: Filter elements for sepg. dust from gases and air comprise thin sheets of material, such as metals or plastics, furnished with large numbers of very small holes of different types, forms and sizes, uniformly or non-uniformly distributed over the surface. The sheet itself may be smooth, rough or roughened. The elements may be formed into any suitable, conventional form of filter, such as a tube or bag. In partic. up to four elements may be arranged in succession one behind the other at spacings of several cm. A large number of small holes of different sizes, shapes etc. produces a similar effect in a synthetic or metal sheet to the natural roughened surface of materials such as cotton or wool. Thus very small particles of dust are better retained than is possible with a synthetic woven fibre. The filters may be cleaned by conventional means, including vibrating or knocking.

Title: Electronic and IR optical system for PCM transmission - has modulation stage with pulse shapers controlled by Schmitt trigger circuit and monostable stage
Inventor: CERNY JOSEF DR
IPC: H04B10/50
Filed: 1980-07-31
Abstract: The pulse modulated transmission system uses time multiplex transmission and infra-red radiation in a quasi optical arrangement. The arrangement has pulse modulated signals passed to a monostable timing stage for transformation into needle pulses and connected by a coaxial cable through a protective resistance to a Schmitt trigger stage for regenerating the pulse edges. This is followed by a delay stage and a pulse shaper operated by increasing edges of the pulses. The radiation system has e.g. three inputs, each with an input capacitor connected across it passing control pulses through a monitoring resistance to an infra-red diode. This is followed by two parallel branches each with a parallel capacitor and resistance, to a pair of switching transistors with a load switch on each base, forming pulse, driver stages. Connected to each input is a monitoring transistor stage with an AND-gate at the output.

Patent DE-3037753-A1 (DE)
Inventor: DUNEMANN KLAUS DIPL ING
IPC: G01L9/04
Filed: 1980-10-06
Abstract: An arrangement for measuring the pressure in a cylindrical cavity by measuring the expansion of the cylindrical cavity in the circumferential direction which results from the pressure within the cylindrical cavity. Such circumferential elongations are measured by a first electrical transducer which is responsive to elongations in the circumferential direction. Contractions in the circumferential direction which results from elongations in the longitudinal direction of the cylindrical cavity are compensated by measuring such longitudinal elongations with at least one further electrical transducer. Such longitudinal elongations may result from bending or tensile stresses. The sensitivity of the electrical transducer for measuring the longitudinal elongations corresponds to the sensitivity of the electrical transducer which measures circumferential elongations, multiplied by the reciprocal of the Poisson ratio. The electrical transducers are connected in series with one another, and in one embodiment, may be formed of wire strain gauges.
