Title: Winning member
Inventor: PIWOWARSKI WLODZIMIERZ DIPL IN
IPC: E21C27/02
Filed: 1984-03-09
Abstract: The invention relates to a winning member, in particular for the winning of in-situ coal by means of a wall combine. The member according to the invention, which is apparent from the drawing, consists of a cutting disc (1) which is attached at a distance equal to the depth of the intended depth A of cut from the front of the cutting/loading part (4) fastened to a common wheel hub (3), the entire width of the winning member corresponding to twice the size of the intended depth A of cut. A splitting wedge (5) or several splitting wedges (5) arranged in a curve shape are at the same time arranged on the inside of the disc (1). The splitting wedges (5) are advantageously triangular in cross-section. The member according to the invention functions in two cycles. In the first cycle, the disc (4) cuts off the in-situ coal to the depth of the intended depth A of cut and the wedges (5) break down the coal, which is fed by the cutting/loading part (4) to the conveyor (7). In the next cycle, the front part of the member works as above, and the cutting/loading part (4) instead wins the residual ridge (8) and at the same time conveys the splintered coal to the conveyor (7). <IMAGE>
Patent DE-3410316-A1 (DE)
Title: Multi-boiler heating installation for liquid heat-transfer media
Inventor: JAEGER FELIX DIPL ING
IPC: F24D12/02
Filed: 1984-03-21
Abstract: To avoid the difficulties arising in multi-boiler heating installations in the interplay of hydraulic network and control installation, the multi-boiler heating installation is equipped with a special pressureless distributor, which has an individual closable short-circuit line for each boiler, and a special control installation. The installation thus equipped makes it possible to supply the heat-transfer medium overflowing from the forward-run distributor to the return-run collector selectively to one boiler exclusively. Consequently, only the return-run temperature of this boiler is affected by the overflowing heat-transfer medium, while the remaining boilers which are in operation can work unaffacted by the overflowing mass flow. In the interplay with the control installation, it is thus achieved that in all load states only ever one boiler carries out the adaptation of the installation to the consumer load, while the other boiler units which are in operation feed their entire output into the network. The installation thus achieves a considerable energy saving at the same time as increasing operational safety.

Patent DE-3418780-A1 (DE)
Title: Method and apparatus for preparing a cut-to-length yarn end for the repiecing of an open-end spinning machine
Inventor: ARTZT PETER DIPL ING DR
IPC: D01H4/48
Filed: 1984-05-19
Abstract: In order to improve the repiecing, particularly in terms of its success rate, at high spinning speeds, the free yarn end cut to a pieceable end and retained after the cutting to length is exposed to a turbulent air flow which sets it in whip-like oscillations. The surface of the yarn end is thereby roughened. The yarn end thus treated is subsequently transferred to the fibre-collecting surface of the open-end spinning machine. The roughening of the surface of the free yarn end is accelerated if the yarn end is whipped against an edge-like projection or a rough face.

Patent DE-3425258-A1 (DE)
Title: Multi-plate brake
Inventor: WEND RAINER DIPL ING
IPC: B23Q1/28
Filed: 1984-07-10
Abstract: The invention relates to a multi-plate brake, the use of which as a clamping means and safety clutch under conditions of restricted space is also advantageous. The aim of the invention is a brake which, with a lower technical outlay and a smaller design, guarantees high braking torques and play-free clamping. The object on which the invention is based is to provide a multi-plate brake in which play in the brake when the torque acting on the brake is reversed in the braked state is avoided and in which the plates separate from one another automatically when the brake is released. The object is achieved by virtue of the fact that the plates assigned to each of the two components to be braked relative to one another are firmly connected to these components. Between the individual plates, at the fastening location, are intermediate layers of essentially the same thickness as the plates situated opposite.

Title: Process for separating out and disposing organic pollutants, in particular polychlorinated dibenzodioxines (PCDD) from flue gases
Inventor: SEIPENBUSCH JUERGEN DIPL ING
IPC: B01D53/72
Filed: 1984-07-14
Abstract: The invention relates to a process for separating out and disposing organic pollutants, in particular polyhalogenated, aromatic compounds from flue gases or other exhaust gases by thermal decomposition of the pollutants at temperatures above 1,000 DEG C, the organic pollutants first being removed from the flue gas absorptively, preferably by means of an activated charcoal filter, then being desorbed at elevated temperatures and then being removed from the desorption gas, which makes up only a fraction of the volume of the flue gas, by incineration at temperatures from 1,000 to 1,400 DEG C. The heating of the desorption gas is carried out using external heat. Expediently, the heat content of the hot combustion gas is utilised, for example to preheat the combustion air.
Patent DE-3428777-A1 (DE)
Title: Backwash filter
Inventor: ROLL JUERGEN
IPC: B01D29/05
Filed: 1984-08-01
Abstract: A known backwash filter is developed for the absorption of oil from an oil/water mixture (untreated water), to the effect that the filter cartridges are formed by filter cylinders 16 closed at the periphery and filled with oil-absorbing material, that, in addition, to backwash the oil-absorbing material, a washing circulation flowing through the filter cylinder 16 is present, which is formed by backwash slides 30, 31 connectable to the two ends of the filter cylinder 16 and that finally wash lines 41, 42 of a washing device 45 are connected to the backwash slides 30, 31. By this means, a pulsed cleaning of the oil-absorbing material located in the filter cylinders 16 is made possible with alternating flow impingement using a wash medium (surfactant/water mixture) on the one hand and heated water on the other. The oil-absorbing material proposed is, in particular, granular polyurethane of precisely defined grain size. <IMAGE>
Patent DE-3429663-A1 (DE)
Title: Simultaneous SO2 and NOx scrubbing
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/60
Filed: 1984-08-11
Abstract: It is known to separate out SO2 and NOx in a scrubbing solution in a single scrubber or in multistage scrubbers, in which the scrubbing solution is enriched with limestone, white lime powder, EDTA and/or a polycarboxylic acid. Since the simultaneous separation does not proceed in harmony, there are high oxidation rates of iron(II) to iron(III) and thus an inactivation of the complex. In order to reactivate the complex portion, according to the invention it is proposed to feed the scrubbing liquid, after contacting with SO2 and NOx, via the outlet of the scrubbing liquid vessel (3) to a solids/liquid separation stage (7) which feeds the separated scrubbing liquid to the activator vessel (8) in which reducing agents (9) are added and, after activation, the scrubbing liquid is returned to the scrubbing liquid vessel (11) by means of a pump (10) and/or is directly reintroduced into the scrubbing process via nozzle pairs (5). <IMAGE>
Patent DE-3432513-A1 (DE)
Title: Apparatus for fastening panel-shaped facade claddings, in particular panels consisting of natural stone
Inventor: GARTNER FRITZ DR
IPC: E06B9/323
Filed: 1984-09-04
Abstract: This device exhibits carrying rails (28) which run horizontally and/or vertically on the building wall and on which the facade panels (14) rest on their underside. For this purpose, the facade panels are preferably designed with a groove (22). Undercut grooves (74) are provided on the carrying rails themselves or on profile parts (70) fitted on the carrying rails. Undercut tongues arranged on cramps (84), located in a groove (92) in the panel (14'), or on angle pieces, fastened on a facade panel, are introduced into said undercut grooves and then engage in a locking manner therein. The groove (74) on the profile piece is designed with a stop (71) on the underside, with the result that the downwards path of the cramps (84) is restricted. In the case of angle pieces fastened on the panels, locking is effected via locking elements which engage with undercut tongues both into undercut grooves on the profile piece and into undercut grooves on the angle pieces. The locking of each panel can be released from outside without neighbouring panels having to be removed for this purpose. If vertical carrying rails are used instead of horizontal carrying rails, then profile pieces can be dispensed with since locking grooves can then be formed on the outer side of the carrying rails. <IMAGE>
