Title: Face/gate transfer
Inventor: ADAM UDO
IPC: E21F13/06
Filed: 1985-06-26
Abstract: Used for the face/gate transition area of winning operations in underground mining and tunnelling is a transfer station in which the gate conveyor, the curve-going conveyor and the face-conveyor transfer means with its transfer table form a unit, which, however, is sufficiently flexible in order to permit adaptations to changing conditions. The face-conveyor transfer means or the transfer table is connected to the advancing units of the gate conveyor so that all parts can be shifted with one and the same advancing apparatus. Via lifting devices, the face-conveyor transfer means can in each case be rotated and swivelled vertically and via a rotary table can also be rotated and swivelled horizontally. At the same time, the curve-going conveyor receiving the spillage coal is also integrated with the transfer station and is of such articulated design that it can be displaced in the direction of the roadway side when required. It is thereby possible to reliably catch all the spillage coal and to push the curve-going conveyor close up to the roadway side. <IMAGE>

Title: Double-acting two-stroke internal combustion engine
Inventor: REST GUENTHER
IPC: F01B9/04
Filed: 1986-03-06
Abstract: The invention relates to a double-acting two-stroke internal combustion engine with at least one cylinder and a twin piston on a rectilinearly guided piston rod with exhaust ports in the middle area of the cylinder, with inlet devices to both working chambers and with at least one charging device connected to the inlet devices. Known combustion engines of this type are expensive in terms of their inlet control and function with unsatisfactory efficiency and high exhaust emission. According to the invention, a compact internal combustion engine functioning with high efficiency and low exhaust emission is created in that the piston rod is of continuous design with at least one hollow chamber and is guided in both ends of the cylinder and that a first flow connection is provided between the hollow chamber of the piston rod and the charge device and alternately open second flow connections are provided between the hollow chamber and each working chamber. In this way the hollow piston rod takes over the inlet control.

Patent DE-3619175-A1 (DE)
Title: Method for laboratory simulation of multipath fading processes
Inventor: BESSAI HORST DR ING
IPC: H04B17/391
Filed: 1986-06-06
Abstract: To simulate multi-path fading processes on microwave links in the laboratory, a frequency-selective variable attenuation is to be achieved in the transmission band. For this purpose, the transmitted signal x is split in familiar manner into a direct and an indirect beam which, before they are recombined, are subject to different attenuation and propagation-time influences. The indirect beam is produced after passing through a  lambda /4 resonator, the terminating impedance and resonator length l of which can be changed. Recombination with the direct beam is carried out by heterodyning the latter with the echo signal returning from the  lambda /4 resonator due to a mismatch, the depth of the attenuation dip being determined by the terminating impedance, its frequency deviation from the centre frequency of the transmission band being determined by the resonator length l. By connecting a number of  lambda /4 resonators, decoupled by isolating amplifiers, in cascade, a number of frequency-selective attenuation dips can be achieved. If the length of the  lambda /4 resonator is changed by adding or disconnecting discrete line sections via a computer-controlled (9) switching matrix (16) and if its resistive termination is changed via a voltage-controlled field-effect transistor (17), an automatic signature measurement is possible (Figure 3). <IMAGE>

Title: Temperature regulator
Inventor: KICHERER ROBERT ING GRAD
IPC: H01H37/36
Filed: 1986-06-07
Abstract: A temperature regulator for electrical heating devices or the like has a two-piece housing (2) (which, in a housing chamber (5), has a regulator switch (6) and, alongside it, an operating element (10) which is provided for said regulator switch (6)) as well as connecting contacts (7) which project freely on its outside. In order to achieve enhanced air-clearance values and leakage-path values and thus to protect the temperature regulator against a significantly increased test voltage, an insulation supplement set (23) is provided which consists of an outer cover (24) for the connecting contacts (7), an additional intermediate plate (25) for covering the housing chamber (5), a switching element (12) with an insulating plate (26), and an opposing holder for the switching contact of the regulator switch (6). In consequence, the temperature regulator (1) can be mounted, by means of its mounting and control side (15), even directly on a metallic chassis, that is to say an electrically conductive chassis, without any additional insulation measures.

IPC: C01B21/40
Filed: 1986-08-13
Abstract: In a process for producing nitrogen dioxide rich gas, (NO2-rich gas) useful for the production of hydroxylamine or nitric acid for example, and/or reaction gas with a high content of oxygen or nitrogen, a nitrogen monoxide (NOx) containing gas, for example flue gas from combustion processes, is passed over or through a reaction mass essentially composed of dimanganese trioxide at a temperature of between 20 DEG  and 80 DEG C, and the resulting manganese nitrate is subjected in a second stage to heat treatment at a temperature of between 200 DEG  and 450 DEG , in order to regenerate the dimanganese trioxide. To obtain oxygen-free nitrogen dioxide, stages of nitrogen dioxide separation and deoxidation can be carried out separately with a preliminary stage at 80 DEG . The oxygen produced in the deoxidation stage can be used for enriching with oxygen the combustion air, thus helping to purify the exhaust fumes of combustion engines. The absorption in an exchangeable container located near the combustion engine and the regeneration of the manganese oxide after the recovery of the manganese nitrate produced can also be centrally carried out on a large scale in bigger units. To produce pure oxygen and pure nitrogen, atmospheric oxygen is added to dimanganese trioxide at a temperature of between 300 DEG  and 450 DEG C and the resulting sorbate is thermally desorbed at a temperature of between 480 DEG  and 560 DEG C, thus releasing pure oxygen.

Title: Process and device for treating fluidised bulk materials in fluidised-bed apparatuses
Inventor: SCHUART LOTHAR PROF DR SC TECH
IPC: B01J8/42
Filed: 1987-03-10
Abstract: The invention relates to a process and an apparatus for treating fluidised bulk materials in fluidised-bed apparatuses. The invention relates to processes in the chemical industry, in agriculture and the food industry and in the raw material industry. The aim of the invention is to prevent the discharge of dust from the fluidised-bed apparatus without separating off the dust on a filter surface, to intensify the processing procedure and to avoid the installation of voluminous separators within or outside the fluidised-bed apparatus. The technical object is to remove, by suitable process steps and means, dust particles and/or liquid droplets entrained by the exhaust airstream in the space above the fluidised bed and to return them to the bed. According to the invention, the object is achieved by combining the effect of processing techniques known individually per se, in that the suspended particles ejected from the fluidised bed pass into the calmed zone of the fluidised-bed apparatus situated above the bed, are there charged in the electrical field built up, are agglomerated and fall back into the bed.
