Abstract: Provided is a quench vessel containing at least two separate internal vessels. A receiving liquor is contained in the first internal vessel and a washing liquid bath is contained in a second internal vessel.
Abstract: A closed loop, carbon monoxide self-contained preferably continuous process and apparatus for the production of nickel or nickel coated objects by nickel vapor deposition (NVD), comprising placing an object to be treated with nickel carbonyl in a deposition chamber; feeding a gaseous mixture of nickel carbonyl and carbon monoxide to the chamber; producing the nickel or nickel coated object and a nickel carbonyl-depleted gaseous mixture; removing nickel carbonyl from the nickel carbonyl-depleted gaseous mixture in a primary and subsequent secondary condensation unit and, preferably, a tertiary condensation unit to produce an essentially nickel carbonyl-free gas. The secondary and tertiary condensation units operably freeze out and subsequently thaw nickel carbonyl and most preferably each comprises a pair of units linked in parallel arrangement operative in alternating, alternate freeze-thaw modes. Carbon monoxide-containing gas is recycled to a nickel carbonyl reactor.

Abstract: A device for applying frosting or icing to a cake or pastry from a cartridge containing pastry dough, frosting or icing. The device has a walled cartridge container and a hand-held gun for dispensing pastry dough, icing or frosting.
Abstract: A mixing apparatus for mixing black liquor from cellulose production with ash from flue gases which is generated on combustion of black liquor. The mixing apparatus contains a cylindrical tank, a stirrer mechanism having a propeller secured on the upper part of a vertical shaft, rotating baffles secured on the lower part of the shaft, and stationary, vertical, radial baffles arranged around, and at a distance from, the rotating baffles. The invention also provides a method for mixing black liquor and ash.
Abstract: A Pulp Mill Recovery installation for producing liquors containing different concentrations of recovered process chemicals or combustion gasses containing different concentrations of process chemicals from a spent liquor obtained from the production of pulp.
