  • Patent number: 4971777
    Abstract: The process removes acid components including sulfur oxides and nitrogen oxides from the exhaust gases of industrial furnaces and includes oxidizing the nitrogen oxide contained in the exhaust gases with the oxygen contained in the exhaust gases at a exhaust gases temperature between 300.degree. and 900.degree. C. before entry of the gases into a first absorption stage, with an addition to the exhaust gases of an organic compound, preferably methanol, as a radical former. After oxidation of nitrogen oxides the exhaust gases undergo a two-stage absorption using aqueous ammonium salt solutions as absorption liquid, whose pH-value is continuously adjusted to less than 5 by addition of aqueous ammonia solution. The mol ratio of NO.sub.2 to SO.sub.2 in the exhaust gases introduced to the second absorption stage is maintained between 0.01 and 0.5 by diverting a portion of the exhaust gases prior to the first absorption stage to the second absorption stage.

  • Patent number: 4969270
    Abstract: A power saw has two oppositely reciprocating saw blades guided and supported in a receiving slot in a support plate. The blades are supported during sawing along shoulders on their outside by lower edges of support sections of the support plate. The arrangement is such that forces generated in operation during cutting press the saw blades together in the area of their teeth. This prevents saw dust, chippings etc. penetrating between the two saw blades. Preferably, the thickness of the saw blade shoulders are not greater than half the thickness of the saw blades, and preferably no greater than the thickness of the support section edges. The teeth of the saw blades may be so ground and arranged that the resultant force on the teeth during cutting also forces the saw blades together at their teeth.

  • Patent number: 4622303
    Abstract: Troublesome foaming in the fermentation of yeast is suppressed by the addition of polyglycol ethers which are derived from saturated and monounsaturated C.sub.16 -C.sub.18 fatty alcohols and which contain on an average of from 1 to 4 ethylene and/or propylene glycol ether groups. Preferred defoamers contain oleyl and cetyl alcohol residues in a ratio of from 3:1 to 1:1, and on average 2 ethylene glycol ether groups. The defoamers do not inhibit yeast growth or lead to premature softening and liquefaction of the compressed yeast.

  • Patent number: 4573621
    Abstract: An electro-magnetic tacker, which can carry out a limited number of driving strokes when its main switch is actuated, has a staple magazine pivotal between a blocking position and an operating position. In the operating position of the staple magazine, a staple blocking member blocks the front staple located in the staple magazine and, in the blocking position of the staple magazine, releases this staple for entry into a staple output channel. A coupling element connected to the staple magazine has an engagement portion which, in the switched-on position of an actuator element of the main switch, is in engagement with this. In this switched-on position, the actuator element holds the staple magazine in the operating position via the coupling element, so that the tacker can be lifted off from a workpiece, while at the same time the operating position of the staple magazine and the blocking action of the staple blocking member are maintained.

  • Patent number: 4470878
    Abstract: In a coking process, coal to be coked is preheated in a cascaded whirling bed drier into which the coal is charged from above and exposed to an indirect heat transfer while whirling in a coal-stream mixture. Hot gas applied to the heating pipes in respective cascades of the drier is branched off from the total amount of hot gases discharged from a dry cooler in which hot coke from the coke oven is cooled by recirculating cooler gas constituted by a partial gas stream discharged from the cascades of the drier and reunited with the other partial stream subject to a heat exchange for generating steam. Steam from the whirling beds is discharged from the cascaded drier, separated from the entrained dust particles, and then the excessive steam is drained in a branch conduit and the remaining steam is compressed and reintroduced into the lowermost whirling bed in the drier.
