Patent DE-2540284-A1 (DE)
Title: Anaerobic and aerobic water treatment - by darkening flow path partly by covers and using water jets for motion
Inventor: LEISTNER KURT
IPC: B01F3/08
Filed: 1975-09-10
Abstract: In an anaerobic or anaerobic/aerobic purifcn. system for water and sewage, the conventionally stagnant water is set in motion along partitions. Air-water jets are used to move, mix and aerate the water, as in the parent patent. Now for anaerobic purification, the flow path is darkened by opaque covers and the water is moved by water, low in oxygen; for simultaneous anaerobic and aerobic purification only a lower layer is darkened. All flow paths are fitted on the walls (and the lower layer under the cover) with adhesive surfaces for mats of biogenic matter. This provides an easy means for combining anaerobic with aerobic treatment.

Abstract: Method comprises continuously moving the cable core through an injection moulding machine having a synthetic thermoplastic material plasticising cylinder and a number of moulds with multiple cavities for formation of a series of plastics discs forming spacers for the outer conductor, injecting the plastics material into the mould, opening the mould, pivoting it away from the core and returning to its start position at high speed and simultaneously pivoting a further mould towards the core and closing the mould at the beginning of a new injection cycle. Prodn. rate is increased by provision of a revolver mould head and a number of injection spindles. Used for forming co-axial cables in which the outer conductor is spaced from the inner conductor (core) with the aid of plastics discs, the dielectric being provided by the intervening air gap.

Title: Trapezoidal corrugation reinforcing filler for sheet metal roof - comprising cardboard panel folded and grooved to fold as insertable unit
Inventor: RECK PETER DIPL KFM
IPC: E04D13/16
Filed: 1975-11-29
Abstract: The filling, stiffening and bridging element is for trapezoid sheet metal corrugations or pleats, as used in trapezoid sheet roofs injected with polyurethan foam for sealing and insulation, usually involving difficulty in filling up to the edge. The corrugation filler presents a flat surface for the adjoining plastic coating. It is in the form of a panel, cut to size, with folds and grooves enabling it to be bent and inserted into the corrugation as a U-shaped unit. Stable hard paperboard is a suitable material. It may have grooves in the bent sections, to enable the plastic to flow in. This can be used for flat roof foaming or sealing and insulating coating in general.

Title: Monitoring device for pulse regenerators - has cabinets between terminal units each with regenerator and error indicator
Inventor: MATTSSON OERJAN MATS
IPC: H04B17/40
Filed: 1976-02-06
Abstract: The monitoring device has a number of cabinets between its terminal units, each with a generator for each of a number of lines. Each cabinet has an error indicator which receives pulse trains transmitted over one of the lines, which are handled by the regenerator, and the error indicator generates a signalling pulse when a section of the pulse train contains at least one error.

Title: Non-grainy raster for half-tone printing plate - has straight lines running broken or unbroken right across the plate
Inventor: SORENSEN ROBERT L
IPC: G03F5/00
Filed: 1976-04-23
Abstract: Square cells of a gravure plate each have three straight line-segments as printing elements. The width of the line-segments is varied to give the tone density required at that cell. Co-linear elements from different cells form broken lines of variable density stretching right across the page. With this form of rater. Moire effects are avoided when line segments of different colours run in slightly different directions. An angular separation of 1 deg. can be enough. In another form, a half-tone original is photographed through a screen consisting of a set of parallel lines (450-1000 per inch) at right angles to which the tone density varies sinusoidally, with a maximum at each of the parallel lines.

Title: Control circuit for accurately adjustable force generator - which has coil firmly connected to point and circuit which corrects force changes due to point travel
Inventor: CORDT WERNER
IPC: G01L1/14
Filed: 1976-08-25
Abstract: The force generator is intended for pressing a test point to a tested object. It consists of a current carrying coil surrounded by a cup-shaped magnet. Travel of the test point firmly connected to the coil and supported by a leaf spring parallelogram is measured by a photodiode whose shading is variable. A differential diode (D) is used, on which the light from an incandescent lamp falls, which passes through a hole in a diaphragm attached to the test point. Photodiode (D) output signal is applied through an integrator (R1, C1) to an amplifier (V2) which corrects the generated force by varying current flowing through the coil (S). An amplifier (T1) is in the lamp (Lp) circuit which controls its brightness by changing its current in accordance with the generated force, thus correcting it. A meter (K) displays the tolerance range in which the force remains constant owing to correction in spite of the point movement.

Title: Cast refractories with very low porosity - obtd. using high velocity gas jet to inject molten metal oxide(s) into mould
Inventor: ACS TIBOR
IPC: C09K3/14
Filed: 1977-01-05
Abstract: Dense refractory materials are made with very low porosity by casting molten metal oxides, the metl is dispersed by a high velocity gas stream so the particles are fed at high energy as a jet into the mould. The particles may be spun into the mould and the distance between the mould and jet gradually increased for gradual or stepwise redn. in the energy of the particles; and/or in the later casting stage, an expansion agent can be added so a dense casting skin is followed by a foamed or expanded core. The molten oxides may have a specific m.pt. and be held in a gas stream until they solidify; alternatively, a melt with no specific m.pt. may be used. The gas stream may contain seed crystals, and the jet sprayed onto a slowly rotating roll or other surface to form a thin solidified layer which is continuously removed and crushed to size. The pref. gas stream uses air, nitrogen, Ar, O2, CO2 or their mixt. Used for the mfr. of refractories, insulation for high temp. use, or abrasive materials.

Title: Linearisation circuit for externally controlled converter - has adder between function generator and control circuit to which additional voltage proportional to current gap duration is applied
Inventor: SALZMANN THEODOR
IPC: H02M7/162
Filed: 1977-05-04
Abstract: The circuit linearises the control characteristic of an externally controlled rectifier. It has a control circuit supplied with an input voltage and supplying the inverter diodes with control pulses. The pulse control angle is a linear function of the control circuit input voltage. A function generator supplies the control circuit input voltage and is itself controlled. It controls the rectifier such that when the rectifier's output current is continuous its output voltage is proportional to the control voltage. An adder (22) is inserted between the function generator (10) and the control circuit (4). An additional voltage (Uz) is applied to it which is proportional to the time (L) of consecutive current gaps, or to the duration of current flow (F) in consecutive current pulses of the output current (I).
