Patent DE-3206840-A1 (DE)
Title: Fuel carburettor for vehicle engines
Inventor: HUTZENLAUB ERNST
IPC: F02M17/26
Filed: 1982-02-26
Abstract: Fuel carburettor for vehicle engines, in which the fuel is vaporised by passing through a fully encapsulated, cylindrical packing of metal whiskers, heated electrically or by the exhaust gases of the engine, and released to a vapour chamber and from this fed by way of a valve, controllable according to the fuel demand of the engine, into the flow of the engine intake air, the fuel recondensed in the vapour chamber being forced back, on closure of the controllable valve, by way of a pressure relief valve into the fuel feed system. It is proposed, for electrical heating of the whisker packing, to provide a coaxial induction coil around this, which can be connected into a high-frequency current circuit.

Title: Process for cleaning filtering separators
Inventor: RITSCHER GUENTER DIPL ING
IPC: B01D46/00
Filed: 1982-05-03
Abstract: A process is described for cleaning individual or serially arranged, hollow filter elements, open on one side and impinged from the outside to the inside with dust-containing gas, in particular filter bags and filter cartridges of different geometrical shapes, from dust separators and air filters. The object of the invention is to allow the cleaning process to be improved at static pressures of 4-8 bar with simplified design of the injector and without additional energy consumption in such a manner that even at underpressures between 2000 and 6000 Pa in the clean gas space, optimal cleaning efficiencies are achieved. According to the invention, this is achieved in that the length between the outlet of the injector nozzle and the outlet of the booster nozzle is in a defined ratio to the internal diameter of the injector nozzle as is the internal diameter of the booster nozzle to the internal diameter of the injector nozzle.

Filed: 1982-05-15
Abstract: In order to avoid temperature sensors and switches, the heating plate, equipped with PTC elements (9), of a hot spot arrangement for an internal combustion engine is connected to an exhaust gas heat exchanger pipe (5) in a heat-conducting fashion. During the cold start and warm running phase of the engine, the heating-up and temperature control of the heating plate (2) by means of the PTC elements to a temperature value predetermined by the resistance dependence of the PTC elements on their temperature take place and after the exhaust gas heating by the heat exchanger pipe (5) is activated the PTC elements remain, as it were, continuously switched off due to their resistance characteristic. <IMAGE>
Patent DE-3221014-A1 (DE)
Title: Ecologically friendly ocean mining
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: E21B4/16
Filed: 1982-06-04
Abstract: A "freezing grab" friendly to the marine ecology for the stripping and raising of ores from deep sea beds is described. Freezing the material to the grab while dispensing with a horizontal movement of the material, which clearly encourages mud emission, permits grabbing of the nodules for vertical transport. In the process, a larger nodule zone is simultaneously stripped with a single elevating grab movement. Liquid air or liquid carbon dioxide or carbon dioxide snow provided in the grab is used to freeze material and water. Also described is a deep-sea drill whose percussion and rotary drive is operated by liquid air stored in the drill, the exhaust air allowing the drilled out material in the hollow drilling nose to be frozen and raised free of mud. Here, cryopneumatics becomes the key to modern ecologically friendly ocean mining.

IPC: B05B12/14
Filed: 1982-06-05
Abstract: The invention relates to a gear pump for volumetric metering, in particular when applying surface coating agents. In order, when changing colours, to reduce the rinsing times and the consumption of solvent for a complete cleaning of the gear pump, a sealable rinsing channel is provided in the pump, which channel bridges with fluid the tooth engagement of the pump gears. It leads respectively into and out of the pump housing at the start and at the end of the tooth engagement in the region of the axial end sides of the pump gears. During rinsing, all that is required is for the pump to be turned over at low speeds of rotation, in which case there is no risk of seizing.
Patent DE-3222830-A1 (DE)
Title: Pipe for air-conditioning systems in underground mining operations
IPC: F16L59/16
Filed: 1982-06-18
Abstract: Cold-insulated pipeline runs for air-cooling systems in underground mining operations have for a long time consisted of a medium pipe as the core and of a curved sheet-metal jacket comprising a plurality of short lengths, and of a cold insulating medium fitted between the sheet-metal jacket, the medium pipe and the end discs at the ends. During installation, the curved jacket length must be expanded and subsequently compressed again. Permanently elastic sealing compounds and screw connections are provided in the overlapping regions. However, because of the high stresses underground, gaps may occur through which air humidity reaches the insulation and makes it unuseable. According to the invention, pressed shells (6), of semicircular cross-section, are now provided which are welded to one another over their longitudinal edge regions (8) and are welded both to the end discs (4) as well as to one another via the end edge regions (10). The insulating means consists of an insulating foam (12) which is inserted into the space between the end discs (4), the medium pipe (2) and the shells (6) via closeable filling holes (5) in the end discs (4). The space is closed such that it is proof against diffusion of water vapour. The shells (6) are constructed to be stiff with respect to twisting and are additionally reinforced by lateral beads. <IMAGE>

Title: Intermediate element for flat roofs
Inventor: BUENDGEN HANS HORST
IPC: E04D13/17
Filed: 1983-03-03
Abstract: An intermediate element for flat roofs, which is arranged, by itself or in association with other identical intermediate elements, between the outer sealing cover layer of the flat roof and the actual roof construction, approximately in the form of the conventional heat-insulating slabs. The intermediate element (1) according to the invention is slab-shaped and has longitudinal grooves (5) and transverse grooves (6) on each slab side and in each case one ventilating hole (7) at each slab end. In addition, each slab element is provided with a peripheral bracket (2) enabling a plurality of intermediate elements to be joined together in the manner of a tongue and groove. Embedded between cover layer and roof construction, the intermediate element (1), or a multiplicity of intermediate elements, forms a system of longitudinal and transverse channels which is connected to the atmosphere in each case via a ventilation pipe insertable into a ventilation hole (7) at each end of the entire system and thus always exhibits atmospheric equilibrium. The production of vapour pressures exceeding atmospheric pressure is thereby prevented. The passage of water into the spaces lying below the flat roof is prevented in the case of an undamaged roof skin. <IMAGE>

Title: Flowmeter counter
Inventor: CHWIERALSKY ALFRED DR ING
IPC: G01F1/075
Filed: 1983-07-11
Abstract: The invention relates to a turbine-wheel flowmeter counter for liquid or gaseous media. The starting torque of the turbine wheel is to be reduced so that the counter responds even at very low flow rates of the medium. For this purpose, there is mounted on the turbine wheel axis (14) a cam disc (18) whose angular position is scanned from outside through the partition (16, 22) by a contactless sensor (11, 19) which is not subject to the effects of force. The output signal of the sensor (11, 19) represents a proportional pulse sequence of the speed of the turbine wheel (6) and can be evaluated by a counter as a measure of the rate of flow. <IMAGE>
Patent DE-3325097-A1 (DE)
Title: Method of construction of annular gap columns for counter-current rectification using glass-ceramic material
Inventor: DILLMANN HEINZ J
IPC: B01D3/28
Filed: 1983-07-12
Abstract: The separation efficiency in the separation by distillation of liquid mixtures in annular gap columns is conventionally based on the heat exchange and mass transfer between the liquid phase, which trickles down on the walls of the concentrically fused-in glass tubes forming the annular gap, and the vapour phase, which rises in the annular gap. The separation results depend on the distance between the surfaces forming the annular gap and on the dimensional stability of the materials forming these surfaces. To increase the dimensional stability and obtain any desired separation, the inner part is now produced from a glass-ceramic material which permits machining on the lathe. A column is further described in which the inner parts are exchangeable and the effective cross-sectional gap areas can thus be changed as desired. In conjunction with the use of glass-ceramic material for the inner parts, an annular gap column is produced, the versatility of which was not hitherto obtainable.
