Abstract: The invention relates to a method for purifying aqueous solutions containing at least one impurity element from the group consisting of arsenic, phosphorus, mercury and other heavy metals and solid matter by precipitation in at least two stages with the aid of precipitation reagents possessing ions capable of forming not-readily dissolved hydroxide precipitate. In accordance with the invention the main part of the precipitation reagent is introduced to the stage or stages following the first stage. The impurity element-containing precipitate formed in the aqueous solution subsequent to adding the reagent is separated therefrom substantially completely, and is returned so as to be present in the first precipitation stage, while that part of the solution which has been freed from precipitate in a later stage is withdrawn from the system. Substantially all the impurity element amount present in the ingoing aqueous solution are separated therefrom in the form of a sludge prior to the second precipitation stage.The amount of reagent introduced to the precipitation stages is suitably adapted so that the ratio of equivalence Me to mole of impurity elements, expressed as X is at least 2, preferably 10-15, in the last stage, and at least 0.8, preferably 1-3, in the first stage.

Abstract: This invention relates to a method of producing carbonaceous bodies, in particular electrodes of parallelepipedal, cubic, or cylindrical shape, e.g. in the production of aluminum or steel by calcining raw shaped bodies (12) containing pyrolyzable substances, in a tunnel type furnace. The method's peculiar aspect is that, at least until the binder within the carbonaceous bodies (12) has turned soft throughout, a consistently divided weight according to the binder used is made to act on the surface(s) covering the carbonaceous bodies (12). Where carbonaceous bodies of elongate shape are to be calcined, they may be disposed vertically so as to utilize their own weight.

Abstract: A method and apparatus of providing a visual representation of a curve image wherein curve image data is provided by a B-Spline equation computed with a forward difference technique using scaled integer variables. The method provides for the scaling of the initial base matrix computation of the geometry vector coefficients followed by the computation of the forward difference interval coefficients using integer arithmetic. The curve coordinate values for each interval are computed from the forward difference interval coefficient integers descaled by the scaling parameter. By employing integer arithmetic in a divide approximation technique, the use of floating point arithmetic is avoided. The apparatus for producing the visual representation of the curve image includes a computational section that provides for pipelined computations of the forward difference interval coefficients to provide high-speed curve coordinate value computation.

Date Jun. 4, 1987.A tape rule or other displacement measuring apparatus comprises a reader means and a member that are relatively movable. The member carries a position track defined by a sequence of alternative markings made in succession along the member. The alternative markings record different values in a pseudo-random sequence which is the result of repetitive operations on a seed consisting of a small number of elements. The sequence has the property that a group of successive markings of length at least equal to that of the seed occurs at a single position in the sequence so that a succession of markings read from the track and of length at least equal to the seed defines an absolute position of the reading means and the member. The reading means has at least three sensors arranged to respond to different locations within each marking with the pattern of the markings and the location of the sensors arranged so that only a single sensor changes state each time that the member moves through an interval of displacement relatively to the sensing means. The states occur consecutively in alternative sequences along the member that are recognizable by decoding logic fed with successive states as a logical value corresponding to one of the alternative markings depending upon which sequence has been followed.
