Title: Mine gallery or tunnel interlocking warping plate - has metal strips welded inside bend forming protrusion with reinforcing element
Inventor: HOPFGARTEN HANS DIPL ING
IPC: E21D11/15
Filed: 1978-06-08
Abstract: The interlocking warping plate is esp. for use in conjunction with tunnels and underground galleries. Interhooked and mutually overlapping warping plates are set between support system and ridge, with stabilising lengthways profiling, and with matching seams and punch-out sections for interconnection. Flat plates without lengthways profiling have S-shaped end bends, in a hook shape with a full-width protrusion. The protrusion (4, 4') projecting on at least one broad side of a warping plate (1) is made up from wire and/or sheet metal strips welded on the side of the bent section (2). This section incorporates a reinforcing element (8) which partially or wholly embraces the plate; this can be a strirrup-shaped wire or strip welded to the outside (9) of the section. This can absorb considerable forces along the line of the gallery.

Title: Purificn. of waste gas contg. noxious gases - where part of heat in impure gas is used to evaporate wash liq. employed in gas scrubber
Inventor: MOHN ULRICH DIPL ING
IPC: B01D53/50
Filed: 1979-02-15
Abstract: The impure waste gas is first divided into two streams; and one stream is fed through a spray dryer and then a dust extractor. The other stream is fed directly into the first gas stream leaving the dust extractor so both streams can be fed through a gas washer, which uses a wash liq. fed through the spray dryer to recover crystallised salts. The second stream may be subdivided into two streams, one of which is fed into the dust extractor, the other being mixed with gas on the inlet side of the washer. The first stream is pref. 10-50% of the initial impure gas. Heat in the initial impure gas can be used to recover salts from the wash liq. in the gas washer.
