Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus for controlling the real and reactive power behavior of a high voltage transmission (HDT) system characterized by a rectifier station connected to a first three phase network and an inverter station connected to a second three phase network.  The rectifier and inverter stations have positive and negative station-halves connected to each other over positive and negative D.C. transmission lines to form positive and negative poles, each station having a common ground or return wire.  Each station is equipped with current and voltage regulators, as wall as control angle and quenching angle regulators whereby in case of the tripping of line protective devices monitoring line current in a faulty pole, and the consequent unloading of the faulty pole, the regulation of the intact pole assumes control for a short time to protect against network transients resulting from the load drop.  In the event of a line disturbance, both the current set-point for the current regulator and the control angle set-point for the control angle regulator of the intact station-half of the intact pole are increased according to preset functions, with the control angle set-point subordinated to the magnitude of the current angle set-point.

Abstract: METHOD AND APPARATUS FOR CONTROLLING THE EFFECT          OF THE CENTRIFUGAL FORCE ON THE STOCK IN PULP                     DEFIBRATING APPARATUS                   ABSTRACT OF THE DISCLOSURE     A method and apparatus is provided for controlling the effect of centrifugal force on pulp stock while being ground in the grind-ing space of a defibrating apparatus defined between a pair of grinding discs which rotate relative to one another in a fluid en-vironment under superatmospheric pressure and corresponding elevated temperature.  The grinding space includes a central portion, a first outwardly extending grinding space and a second outer grinding zone extending at an inclined angle from the first grinding zone.  Pulp stock to be ground is introduced into the central portion and ac-celerated through the first and second grinding zones by centrifu-gal force generated by the rotating discs.  The inclined grinding zone serves to split the centrifugal force into a vector perpen-dicular to the direction of flow of the pulp material and a vector aligned with the axial flow to reduce the accelerating force on the pulp grist in the direction of outward flow.  By reducing the out-ward acceleration, the dwell time of the grist in the second grind-ing space is increased, resulting in optimum utilization of the en-tire grinding space for optimum refining efficiency.

Abstract: ABSTRACT OF THE DISCLOSURE     The specification discloses a method of analysing a liquid biological medium such as human blood in order to detect or identify viruses therein having antigen properties (i.e. virus antigens) or erythrocyte or cell antigens or antibodies. According to the disclosure in order to determine whether a biological medium contains virus antigens or erythrocyte or cell antigens or antibodies, a method of analysis is used involving immunological reactions between cells or particles and a serum and then between the thus treated cells or particles and an antiglobulin, the method being characterised in that the reaction medium containing the cells or particles and the antiglobulin is introduced into a vessel, the wall of which has a point of convergence or apex situated on the axis of symmetry of the vessel, molecules capable of an immunological reaction with the antiglobulin having been fixed on the walls of the vessel, and the reaction medium is subjected to a centrifugal force substantially parallel to the aforementioned axis under con-ditions such that at least the cells showing a positive reaction, i.e. an analytical reaction performed on a sample of the biological medium containing the antigen or antibody to be identified, progressively stick to and remain stuck to the vessel wall by bonding forces of a first kind, i.e. immunological bonding forces involving the antiglobulin, which are added to bonding forces of a second kind, whereas the cells showing a negative reaction at the end of centrifuging are not stuck to the wall except by bonding forces of the second kind, so that the last-mentioned cells are collected at the apex of the vessel by applying a centrifugal force sufficiently strong to destroy the bonding forces of the second kind (i.e. connecting a negative cell to the vessel wall) but not sufficient to destroy the sum of the bonding forces of the first kind and the bonding forces of the second kind (i.e. connecting a positive cell to the vessel wall).

Abstract: SPECIFICATION                 ABSTRACT OF THE DISCLOSURE           A knee joint prosthesis comprises a femoral component having laterally spaced-apart condylar portions shaped to match generally the shapes of the condylar surfaces of the femur and a tibial component having a plate-like platform portion which includes laterally spaced-apart concavities in the external surface, each of which receives and supports one of the condylar portions of the femoral component in all positions of the leg.  The femoral component has a box-like intercondylar portion interconnecting the condylar portions and defining an intercondylar recess which receives a post that extends upwardly from the tibial component.          At and near full extension of the leg, any tendency for posterial dislocation of the femur results in engagement between the anterior surfaces of the post and recess to prevent posterial dislocation of the femoral component relative to the tibial component.  At leg flexions approaching full flexure, the posterior surface of the recess engages the posterior surface of the post in the event of a tendency toward anterial dislocation of the femur, thereby preventing anterial dislocation.        Large antero-posteriormovements and dislocation are prevented in all leg positions by engagement between surfaces of the post and recess.  The post and recess are shaped and dimensioned to permit essentially normal rotation and lateral angulation of the prosthetic joint in all positions.

Abstract: ABSTRACT OF THE DISCLOSURE A burner system for gaseous or liquid fuels adapted for insertion through a circular tile opening in a furnace wall, comprising a burner tube for alternate supply of gaseous or liquid fuel.  The burner tube is coaxial with and inserted into said circular opening.  A first stationary annular vane assembly comprises a plurality of symmetrically-placed tangentially-directed vanes enclosing a cylindrical open chamber coaxial with and up-stream of the burners.  A second movable assembly of radial vanes is adapted to slide axially about the burner tube and to be moved from a first position where it is entirely outside of the chamber space, inwardly to a second position, where it is entirely inserted into the chamber space and inside of the first annular vane assembly.  Combustion air is passed at selected pres-sure through the tangential vanes and into the chamber space.  When the sec-ond vane assembly is moved to its first position, the tangential vanes pro-vide a swirling helical flow of air into and axially along the chamber space, and into the downstream of the burners, providing a swirling flame.  When the movable vane assembly is in its second position, inside of the chamber space, then the tangentially-directed air flowing through the first vane assembly flows into the second vane assembly with its radial vanes.  This completely cuts off the helical flow, and causes only axial flow of air past the burners and into the flame zone.
