Abstract: A steam generator consists of a chamber (12) with heating elements (13), fed with water by a pump (11) and equipped with an electrically- controlled valve (15) for expelling steam. It also has a regulator in the form of a temperature or pressure sensor (14) to monitor the amount of water in the chamber and to actuate the pump. The regulator is connected to an electronic system which carries out a succession of measures and operates the pump as a function of the temperature or pressure in the chamber (12). The chamber can comprise a metal container (12a) in thermal contact with the sensor (14), which incorporates an electrical resistance such as a thermistance, and the heating elements are controlled by the electronic system on the basis of data supplied by the sensor.

Title: Vehicle spring suspension arrangement
IPC: B60G5/00
Filed: 1984-02-16
Abstract: A vehicle such as a 6x2 tractor having at least three axles is provided with a novel leaf spring suspension (1) for its middle axle. When the load, imposed on the chassis by a semi-trailer, exceeds a predetermined threshold, the free, rear, end of the leaf spring (1) engages the under-surface of the upper portion of a slipper bracket (4) attached to the chassis, and the middle axle takes a proportion of the load. With loads below the threshold, the free end drops through a vertical "air gap" and is held by a lower supporting arm on the slipper bracket, the middle axle being unloaded. The rear, driving, axle is thus more heavily loaded whenever the vehicle is part-laden, ensuring greater traction.

Abstract: Chlorine may be recovered from residues from the fluidised bed chlorination of iron-containing metalliferous oxidic materials, such as ilmenite, bauxite, chromite, wolframite, scheelite, tantalite or columbite, the residues containing condensed iron chloride and blow-over bed solids, by heating the residue to revolatalise the iron chloride and reacting it with oxygen. The quantity of iron chloride in the oxidic material is controlled relative to the quantity of blow-over carbon so that the quantity of carbon is sufficient on combustion to provide the required heat but is insufficient to cause undue dilution of the chlorine produced by virtue of its combustion products. Chlorine of a concentration suitable for direct recycle to a chlorination process, e.g. of 30% to 50% volume concentration is produced.

Abstract: 1470417 Distilling zinc ISC SMELTING Ltd 12 Sept 1975 [11 Oct 1974] 44066/74 Heading C7D Zinc vapour is condensed in a multi-stage condenser in each stage of which the vapour is contacted with a spray of molten lead produced by a rotary impeller immersed in a pool of molten lead and the temperature of the molten lead in an intermediate stage is maintained in the range 475-515C. In the apparatus shown zinccontaining vapour is passed from inlet 1 to outlet 2 of a three-stage condenser whose first stage has impellers A and B while impellers C and D provide the second and third stage respectively. Molten lead passes in countercurrent to the gas and is recirculated through a cooled launder 4 to form a two phase melt, the upper zinc layer being separated at 5. Temperature control at the intermediate stage may be effected by heating the said intermediate stage, by returning some of the hot lead leaving the condenser directly to the intermediate stage through duct 9, or by feeding some of the cooled lead after it has left separator 5 direct to the first stage through duct 10. In this last method the reduced flow of lead through the intermediate stage causes an increase of temperature at that stage. In a further embodiment Figs. 2-5 (not shown) a part of the lead spray in the first condensation stage is caught in ducts (15) sloping down towards an aperture (14) in baffle 7 and the lead so caught is returned to the intermediate stage directly through the said aperture.
