Abstract: Provided is a novel device for dispensing pastry dough, frosting or icing from a cartridge The device has a cartridge container and a hand-held gun. A hydraulic cylinder having a piston is coupled to the cartridge container. The piston acts on a plunger of the cartridge to apply pressure on the pastry dough, frosting or icing to permit the pastry dough, frosting or icing move to the gun to be dispensed. An alternative device utilizes a frosting cylinder in place of the cartridge.

Abstract: A method for impregnation and chemical digestion of lignocellulosic material and recovery of pulping liquors. A spent impregnating or cooking liquor is withdrawn and sulphurous compounds are recovered therefrom in a partial oxidation reactor. These sulphurous compounds are converted into hot liquid elemental sulphur which thereafter is mixed with a hot sulphide containing liquor to provide a polysulphide liquor with a concentration greater than 10 g/l and which is essentially free from thiosulphate. This polysulphide liquor is used for carbohydrate stabilising impregnation and/or for cooking at a relatively low temperature.

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.
