Title: Overlap pcm coder/decoder with reaction time compensation

Abstract: OVERLAP PCM CODER/DECODER WITH   REACTION TIME COMPENSATION            Abstract of the Disclosure A PCM coder/decoder circuit is disclosed employing a counter that counts clock pulses until a transmitting ramp voltage equals that of an outgoing speech sample.  The encoded count is transmitted in complemented form to the distant station where it is eventually entered into a counter similar to that of the transmitting station.  Clock pulses are then applied to the receiving counter until a carry is generated at which time a receiving ramp waveform is disconnected from a decoding capacity.  The counter at the receiving station is enabled prematurely to generate the count so that the "reaction time" of the physical circuit components is compensated for.  Compensation of this reaction time is important in reducing the nonlinear distortion that would otherwise be introduced when the ramp waveforms that are employed are of the companded type.  The circuit operates in an overlap fashion, encoding and receiving in one field and decoding and transmitting in another field.  Control time slots are interspersed between these fields and the control time slot intervals are advantageously employed to augment the code in the counter.

Title: Electrochemical gas detector for the detection of gas  traces
Inventor: BREUER WOLFRAM
IPC: G01N27/49
Filed: 1977-05-13
Granted: 1980-08-05
Abstract: ABSTRACT OF THE DISCLOSURE           An electrochemical gas detector based on an electrolytic measurement cell having a normally solid organic electrolyte.  The gas component to be detected diffuses out of the gas chamber at a three phase border (electrolyte-electrode-gas chamber) and there causes a change in the electrochemical equilibrium.  As a result in an outer closing circuit a measurable electrical current is produced.  The electrolyte consists of an anhydrous organic gel with a very low vapour pressure. The gas chamber adjacent to the three phase border constitutes a partly sealed cavity, which is in communication with the gas atmosphere to be examined via an absorption filter selectively permeable to the measurement component. The length of the cavity is dimensioned so as to be so short that practically no back diffusion of the measurement component through the filter takes place.

Abstract: O.Z. 28,910 ABSTRACT OF THE DISCLOSURE: A process for the manufacture of hydrocarbon oils by hydrocracking of coal under pressure, more specifically a process for the manufacture of coal oils by hydrocracking of coal under pressure, in 2 stages, in which, in a first stage, finely ground coal is treated with catalysts and oil to give a paste and is converted with hydrogen, at an elevated temperature and superatmospheric pressure, at least partially into distillable products (this reaction being carried out in the liquid phase), whilst in a second stage the hydrogenation is taken further, over a fixed catalyst (this stage being carried out in the gas phase or a mixed phase). The object is to increase the throughput in the liquid phase and enable this stage to be carried out at relatively low pressures, of from 100 to 300 bars, to make it possible to carry out the further hydrogenation in the gas phase by utilizing the latent heat of the product from the liquid phase, and to obtain the non-utilizable residue of the products in a clean form.

Abstract: PLANE WAVE LENS            Abstract of the Disclosure Various aspects of electro-magnetic testing are facilitated by inserting a foamed plastic dielectric lens at a particular position between the radiating source and the test aperture.  The lens is constructed according to electro-optic formulae and the radiation wavelength to produce a plane wave of uniform phase.  This makes possible testing under far field conditions in test cells of modest size, which has heretofore been possible only with elaborate parabolic reflectors.  The lens can be manufactured from any plastic having a dielectric constant in the range of 1.05 to 1.5 by either blowing the plastic in a suitable mold, or by machining from a preformed foam block.    In accordance with a further aspect of the invention, as described in the Supplementary Disclosure, to control extraneous energy contributed by reflections from the flat face of the lens, this surface is provided with two layers of high-performance absorber material.  The absorber layers are loaded with conductive carbon to provide desired insertion loss and attached to the flat face of the lens.

Abstract: 26.10.78                                            PHD 77-126 ABSTRACT:              The invention relates to a radiation detection device, comprising a housing which comprises an entrance window and in which at least one ionization chamber detec-tor is arranged. The detector comprises a flat high-voltage electrode which is directed transversely of the entrance window and a flat collector electrode which is arranged to be at least substantially parallel thereto. The end faces of these electrodes which face the entrance window are in electrically conductive contact with a flat auxiliary electrode which extends parallel, to the entrance window. As a result, a small direct current flows in the direction transversely of the other electrodes during operation, because the auxiliary electrode has a low electrical con-ductivity. Consequently, the electrical field in the ioni-zation chamber detector is very homogeneous, with the re-sult that optimum adjustment of the detector in respect of measuring speed can be realized.
