摘要： The invention relates to a blasting method for removing coatings of paint, varnish or like substances from objects coated with such substances, in which the objects are cooled in a condensed gas, e.g. liquid nitrogen, and then subjected, in a chilled state, to the effect of a blasting agent, e.g. steel shot, delivered by a blasting machine. The coating fragments dislodged are collected together with the blasting agent and mutually separated one from the other in a separator. The recovered blasting agent is then returned to the blasting machine. The method is characterized by adding an absorbent to the blasting agent in the blasting machine.

摘要： The invention relates to a method for recovering non-ferrous metal from a dross starting material containing this metal, optionally together with non-ferrous metal scrap, and/or a starting material comprised of such scrap. The method comprises introducing the starting material into a rotary furnace or rotatable converter provided with a refractory lining, heating the starting material to a temperature above the melting point of the metal while rotating the furnace either continuously or intermittently, and removing the resultant molten metal from beneath the overlying dross residues. The method is characterized by heating the starting material in the absence of a protective salt layer with the aid of a so-called oxy-fuel-burner which is supplied with a fossil fuel and with a gas that contains at least 80 % oxygen, and by rotating the furnace at a speed of 5 r.p.m or lower.

摘要： There is described a method for treating delimed and bated hides, i.e. pelts. According to the inventive method, the pelts are brought to a suitable mineral tanning state and then tanned with mineral salts. The inventive treatment process corresponds to the conventional processes of pickling, tanning and basifying. The inventive method includes the treatment of pelts with weakly acid treatment liquids while supplying carbon dioxide and additions of tanning mineral substances subsequent to pretreatment, without or with the addition of solely a small amount of liquid, wherein the quantity of treatment liquid is supplemented after a predetermined treatment time.

摘要： A system for forming hollow pressed glass articles (20) utilizes a flow of cryogen that is mixed with air supplied by tube (50) to provide a cooling gas that enables newly pressed articles to be removed from their molds after a thin skin of solidified glass has been formed on internal surfaces of the articles. Two flows of cryogen are used, one being a gentle, substantially continuous flow of cryogen gas, the other being a controlled intermittent flow of cryogen vapor in liquid and/or gaseous form. To assure a proper introduction of cryogen vapor, and to prevent debilitating accumulations of ice within and about the tube that is used to inject high pressure cryogen, the high pressure injector tube (62) is surrounded by a low pressure cryogen tube (64), through which a flow of low pressure cryogen gas is maintained on a substantially continuous basis.

摘要： The disclosure relates to a method in processing, in particular the treatment of cellulosic materials, in a treatment zone with a gas in a liquid, the gas being added to the liquid and being transported therewith to the treatment zone. The method according to the present invention is characterized in that, to increase the capacity of the liquid to retain and transport the gas, the foaming properties are improved and/or particles are added to the liquid with a capacity to retain gas bubbles. The foaming properties of the liquid may be increased by adding foaming agents, by deactivating and/or removing ions which hamper or hinder present foaming agents from forming foam, by deactivating and/or removing ions by means of complex formers, deposition agents or ion exchangers or by adding cellulosic fibres.
