Title: Modular electronic apparatus
Inventor: KLEIN KLAUS DIPL ING
IPC: H01M50/224
Filed: 1988-10-10
Abstract: The invention relates to a modular electronic apparatus. Known electronic apparatuses, especially data processing apparatuses, are constructed such that various assemblies must be assembled mechanically with specially matched dimensions, for their electronic functions. The electronic apparatus according to the invention simplifies a modular construction in that printed circuit board assemblies (BG) and a power supply module (SV) are located on opposite sides of a housing (GH) and, in the interior of the housing (GH), can be plugged onto the respectively opposite sides of the rear-panel wiring board (RP) (motherboard) mounted there.

Patent DE-3834924-A1 (DE)
Title: Optical aiming device for a firearm, especially for a hand-held firearm
Inventor: TROST SIEGFRIED
IPC: F41G3/10
Filed: 1988-10-13
Abstract: In addition to other factors, causes of poor hit results may be:     - tilting of the weapon,   - incorrectly estimated range and   - non-optimum sight graticule.   The object and objective of the invention are to overcome these causes of errors, which lead to poor hit results. Such a device is at present unknown. A sphere (3), which moves within a curved, transparent, hollow circular cylinder (2) which is closed at both ends, in an optical aiming device is used as a tilt indicator. The diameter of the sphere (3) covers a circular area of known diameter at a specific round range of, for example, 300 m and thus makes it possible to estimate the range. Two rings (5) and (6) of different size enable rapid acquisition of the target and, subsequently, precise aiming in the case of the sight graticule. The field of application of the invention is firearms, especially hand-held firearms. <IMAGE>

Patent DE-3837390-A1 (DE)
Title: Standstill sensor
Inventor: BEK MANFRED DIPL ING
IPC: G01P13/00
Filed: 1988-11-03
Abstract: In a standstill (stoppage) sensor for a rotating shaft, a measuring toothed wheel which is connected to the shaft is used in conjunction with a distance probe to produce an output signal as long as the measuring toothed wheel is rotating. In order to suppress the output signal when the measuring toothed wheel is merely vibrating, there is connected downstream of the transmitter a trigger which has a turn-off value differing from a turn-on value and is switched to and fro by the output signal of the transmitter, and thus supplies an output signal, only when the amplitude of the probe output signal is so large that it passes through both threshold values. The profile steepness of the teeth of the measuring toothed wheel is permitted only to be so large that in the event of rotary vibrations of the shaft the output voltage of the probe remains within the hysteresis zone of the trigger which is given by the two threshold values, so that said trigger suppresses output signals of the probe which are caused by the vibration.
Patent DE-3840517-A1 (DE)
Title: Process and apparatus for the production of energy from biomass
Inventor: HOEFER CHRISTIAN
IPC: H01M8/0656
Filed: 1988-12-01
Abstract: A process and an apparatus are described for the production of energy from biomass, the biomass (at 10) if required ensiled or pelleted and fed to a biogas installation (12) in which biogas (arrow 20) and natural fertiliser (arrow 22) are produced. The biogas and/or natural gas from a public gas grid (26) is burnt in a first apparatus (30) and converted into thermal energy and/or electrical energy. By means of the electrical energy generated by the first apparatus (30) and, if necessary, by electrical energy from a public electricity grid (40) an electrolysis cell (34) is operated in which water is divided into hydrogen and oxygen. Hydrogen and oxygen can be converted back to electrical energy in a fuel cell (62), but the oxygen can also be used to improve the quality of wastewater (effluent) (at 60). The hydrogen can be stored in a storage facility (57) and/or be converted in a second apparatus (78) into thermal energy and/or into electrical energy or be used to drive motor vehicles (96) equipped with hydrogen engines. <IMAGE>

Patent DE-3917214-A1 (DE)
Title: Method for the bit-serial transmission of datawords
Inventor: FUNK GERHARD
IPC: H04L25/49
Filed: 1989-05-26
Abstract: The bit-serial data transmission method assigns binary datawords (C1, C2, ..., Cn) in a channel code to binary datawords (D1, D2, ..., Dn) of an output code before transmission in a transmission channel. This data transmission method is to be distinguished by a high transmission efficiency. This is achieved by the datawords (D1, D2, ..., Dn) of the output code exhibiting an octet structure and a dataword with twelve binary characters of the channel code being assigned to each dataword of the output code. Each dataword of the channel code also exhibits six equal binary characters and six binary characters which are inverse thereto. The binary character sequence in each dataword (C1, C2, ..., Cn) of the channel code is also selected in such a manner that in the bit-serial succession of datawords (C1, C2, ..., Cn) of a message (10), three identical binary characters at the most occur next to one another. In addition, the channel code is selected in such a manner that certain binary character sequences (SZB, SZE) provided for the message synchronisation do not occur in arbitrary sequences of datawords (C1, C2, ..., Cn) of the channel code. <IMAGE>
