Inventor: KOENIG FLORIAN
IPC: H04R5/033
Filed: 1992-10-30
Abstract: The stereo headphones have at least one sound transducer for each headphone supported by a holder (1) at a position which is offset from the headphone capsule vertical plane (L) and which lies below the headphone capsule horizontal plane (H). One sound transducer (2) is arranged pushed back opposed to a direction of sight. Pref. the holder supports three miniature loudspeakers (2,3,4), two of which lie on either side of the vertical plane in respective lower quadrants of the hearing capsule, the third (4) lying along the vertical plane (L) at the bottom of the hearing capsule.

Title: Sensor output signal peak detection and processing circuit - includes two peak-value-holding circuits operating on phase-adjusted input and differential output of bridge
IPC: G01D1/16
Filed: 1992-11-05
Abstract: One side of the bridge (9) is supplied with an AC signal from an oscillator (10), and its opposite diagonal (c-d) is wired to a differential amplifier (11). The input signal is applied after phase adjustment (13) to one peak-value-holding circuit (31), while the other (32) holds the peak output (12). The signs of the peaks are discriminated (33) for control of the output stage (36) following digitisation (34) and buffering (35). USE/ADVANTAGE - With, e.g., magnetostrictive torque sensor, strain gauge or differential transformer-converter, precision of detection is improved with exclusion of influences of phase difference dependent on sensor variation.

Title: Two band single element short wave antenna - acts as half wave surface wave dipole and twice five eighths  lambda directional antenna with third harmonic excitation
Inventor: MENZLEWSKI VICTOR
IPC: H01Q5/48
Filed: 1992-07-13
Abstract: In the HF range, a half wave antenna for surface wave resonance at the fundamental (e.g. 7 MHz) must be extended by about 3.5 percent to resonate precisely at the third harmonic (21 MHZ). Thus two one-eighth lambda coaxial conductive loops with air dielectrics are replaced by coaxial cable lengths with a specific dielectric. With surface wave resonance excitation the lambda over eight elements reach their predetermined electric wavelength of twice 45 deg. and supply the five-eights lambda elements in correct phase and impedance. The geometric spacing of the colinear radiation elements is reduced from 90 deg. to 70 deg. If the antenna is excited as a half wave dipole the outer conductor of the coaxial cable is part of the length of the  half-wave surface wave dipole. ADVANTAGE - Improves transmission either in VHF/UHF or Hf regions with one-element antenna at fundamental and third harmonic.

Title: Method of processing a serial digital data signal
Inventor: EBNER ANDREAS
IPC: H04N5/44
Filed: 1993-03-11
Abstract: To achieve a reliable information more rapidly in the decoding of low-frequency signal elements of a serial digital data signal contained in a television signal, the low-frequency signal element is sampled at the same sampling rate as is used for sampling the high-frequency signal elements in the case where the low-frequency signal element only carries a single information unit. The sampling rate corresponds to the frequency and phase of the high-frequency signal elements. The sequence of the samples produced during the sampling of the low-frequency signal element is subjected to a majority check.

Title: Pipeline system for transporting district heat
Inventor: HOMANN JOERN
IPC: F16L9/18
Filed: 1993-07-17
Abstract: A description is given of a pipeline system which is intended for transporting district heat and comprises a multiplicity of individual pipeline sections which are connected to one another. Each individual pipeline section comprises a corrugated metallic inner pipe, a corrugated metallic outer pipe, a heat-insulating layer which is located between the inner pipe and the outer pipe and consists of chemically produced polyurethane foam with special reaction data, and a plastic outer casing located on the outer pipe. The outer pipe is configured, in combination with the plastic outer casing, such that the soil and traffic loads which are to be expected when the pipeline is laid in the ground are absorbed by these two structural elements alone. The pipeline system is constructed such that, upon operational loading, the volume of the polyurethane foam does not fall below 80% of the volume of the annular chamber between the inner and outer pipe.

Abstract: A process for producing an injection-moulded article which consists of at least two different thermoplastic materials is to be designed such that this injection-moulded article can be produced efficiently and inexpensively. This is achieved by the different thermoplastic materials (14, 15) being injected one after the other via a common runner (9), using an injection mould (1) which is at least partially designed in such a way and/or can be activated in such a way that the injection mould (1) or at least part of the same is filled in frontal/laminar flow from the runner (9). The filling operation is controlled alternately with the different thermoplastic materials (14, 15) but with a continuous transition one into the other in such a way that the thermoplastic material (14 or 15) of the desired characteristics according to the moulding process is in each case located in the section intended for this material of the injection mould (1) or of the moulding or preform (2) (single figure). <IMAGE>

Title: Simulation arrangement for fading phenomena, e.g. as appearing during directional transmission
Inventor: SCHMITZ GEREON
IPC: H04B17/391
Filed: 1993-12-03
Abstract: The depth of fading and their frequency levels can be continuously varied by electronically adjustable components.  The transmission signal is split into a direct and an indirect beam which are subject to different attenuation and cycle length effects before being joined together again. The indirect beam passes through a quarter wavelength resonator with variable terminal resistance and resonance length. It is joined with the direct beam by superimposing it with the echo signal from the resonator. The depth of the damping is determined by the terminal resistance and the frequency depends on the average frequency of the transmission band from the resonator length.
Patent DE-4343077-A1 (DE)
Inventor: KUBITZ RAINER DR
IPC: C02F1/467
Filed: 1993-12-16
Abstract: The cell has one or several particle bed electrodes 3 consisting of light, electrically conductive pellets which maintain upward pressure on the current feeder (4, 5), placed above them, by means of their buoyancy and by an upward flow of electrolyte, and electrolyte is pumped continuously into the cell but withdrawn periodically by e.g. a syphoning device 15. The periodic lowering of the liquid level causes movement and rearrangement of the pellets to prevent clogging. This improves the deposition rate, quality of the deposit and facilitates unloading. The deposition of the pollutant metal on the pellets causes them to sink eventually into a trap from where they may be removed. <IMAGE>
