A method is disclosed for achieving improved reduction efficiency and economy in the reduction of particulate metal ores, e.g. iron ore, in a vertical shaft, moving bed reactor having a reduction zone in which a heated reducing gas is caused to flow through a portion of the ore bed to reduce the metal ore thereof to metal; e.g. sponge iron. The improved efficiency and economy is achieved through a...

In strand user devices such as a yarn storage feeder system of the type disclosed in U.S. Pat. No. 3,776,480 and having a yarn storage unit upon which a quantity of yarn is maintained from a yarn supply for intermittent withdrawal and delivery to yarn consuming means, a significant improvement in efficiency of the strand user device is achieved by incorporating strand guide means which are operabl...

Steam, for example, is produced from aqueous brine, by a system that employs preferably hot waste fluid, and nozzle means and rotary separator means generally of a known kind per se. The method steps include transferring the waste heat of combustion source (22) to the brine flowing in heater exchanger coil (23), expanding the hot brine through nozzle means (24) to form a jet of steam and liquid dr...

1. Apparatus for determining oxygen concentration in gases, liquids and tissues by measuring the decrease in light emission of a luminescent surface (Fst) with an excitation light of a certain wave length comprising a light source (L) for producing the excitation light and a device (F2 , PM) for measuring the intensity of the emitted light, characterized in that the surface (Fst) is the surface of...

An industrial truck comprising a travel drive and a steering drive and sensors for scanning a trail laid in the ground and for guiding the vehicle along that trail includes a microprocessor for delivering steering commands to the steering drive. At least two pairs of sensors consisting of coils are connected to a multiplexer. Only a single processing channel is provided between the multiplexer and...

The shell is removed from a crustacean by creating a pressure difference across the shell. Initially the crustacean is heated until body liquid adjacent the shell is just below boiling point. The pressure on the crustacean is then suddenly lowered to induce the liquid to boil and thereby create the pressure difference across the shell. After pressure treatment, the crustaceans are projected into a...

Polyurethane foam products comprising a foam filled with a foam and a large amount of combustion retardant materials are described. The foams are prepared by foaming a polyurethane foam-forming diisocyanate and polyol around pre- formed polyurethane foam chips having incorporated therein solid combustion retardant materials. The polyurethane foam-filled foams are suitable for furniture upholstery ...

Vapour phase hydrolysis of scrap polyurethanes, especially flexible polyurethane foams, is improved through the use of catalytic amounts of basically reacting alkali metal or alkaline earth metal compounds applied to the foam prior to hydrolysis.

A sound insulating double glazing unit comprises a laminated pane (2) and a monolithic pane (3) connected together and sealed at their edges in spaced apart relationship 10 to 20 mm apart. The laminated pane comprises two sheets (7, 8) of 3 mm glass adhering to an intermediate layer (9) of polyvinyl butyral 0.38 mm thick over the facing surfaces of the sheets, and the monolithic pane (3) is a pane...

Chromium is electroplated from a bath which includes a trivalent chromium salt and chloride ions. Chlorine gas production at the anode is reduced through the incorporation in the plating bath of at least one salt having a nitrogen containing cation and at least one soluble salt yielding from about 0.001 mole per mole liter to about 0.01 mole per liter of bromide ion. The bath can further include s...
