  • Publication number: 20140257286
    Abstract: The present invention relates to an anatomically personalized and mobilizing external support, a method for manufacturing is, as well as the use of a component of an invasively attached external support in determining the path of the joint being supported. In the method according to the invention, the kinetic dynamics of the joint are measured with the aid of a component of an external support invasively attached to two bone groups, on the basis of which an external support is arranged between the bone groups.

  • Patent number: 4883599
    Abstract: A method for cleansing metal-containing solutions, particularly, but not exclusively, process water which contains such metals as mercury, cadmium and/or lead, where the metals concerned are present in water-soluble form, such as the form of a chloride complex. The method is characterized by passing the solution through an ion-exchange material (4) which consists essentially of sulfhydrated cellulose, the metals being adsorbed in the sulfhydrated cellulose; regenerating the ion-exchange material (4) subsequent to the adsorption of a predetermined quantity of metal, by rinsing the ion-exchange material with an aqueous solution that contains hydrochloric acid (HCl) at a concentration of at least about 1 molar HCl; and precipitating the metals concerned in sulphide form, in a known manner, from the liquid that is eluted from the ion-exchange material (4) in the aforementioned rinsing process.The invention also relates to apparatus for carrying out the method.

  • Patent number: 4583999
    Abstract: A method of flue-gas cleaning comprising the separation of water-soluble substances from flue gases containing water vapor. The invention is characterized in that the flue gases are caused to be cooled by direct contact between flue gas and atomized water in two or more separation steps, where in a separation step (2) subsequent in the flow direction of the flue gases the flue gases are cooled by atomized water to a temperature, at which the water in the flue gases is condensed out, which water is collected and thereafter both recirculated for utilization in said subsequent separation step (2) and introduced into a separation step (1) prior in the flow direction of the flue gases. In said prior separation step the water is atomized and meets uncleaned flue gases, the water-soluble and potentially water-soluble substances of which thereby are solved in the atomized water. The water thus impurified is collected for further treatment.
