Abstract: ABSTRACT OF THE DISCLOSURE         An electromagnetic device comprises an outer annular member and an inner member, the two members each having a helical rib on their presented surfaces.  Two presented side faces of the ribs define working surfaces and on one of the working surfaces is defined a groove which extends the length of the rib and the groove accommodates an electrical winding which when energised creates a pair of magnetic poles on the one working surface.  The magnetic circuit of the poles includes the other working surface and the two surfaces move towards each other to reduce the mag-netic reluctance thereby causing relative movement of the members.

Abstract: Abstract of the Disclosure Disclosed is an electronic hybrid circuit which enables telephone conferences to be set up.  The known systems have various limitations.  For example, in one type of system, more than one person cannot be heard simul-taneously.  Known systems also tend to be fairly limited in the number of telephones which may be connected up in a single conference.  Otherwise, sig-nal degradation takes place due to worsening signal to noise ratio and impedance matching problems.  The present invention provides an electronic hybrid circuit which enables a large number of telephones to be connected in a conference set up and which has a number of advantages, including the fact that more than one person say talk at one time.  The disclosed hybrid circuit comprises a local input and output and a system input and output.  The local input is connected to an analog switch and to a comparator which provides a control voltage to turn on the analog switch if a signal on the local input exceeds a predetermined minimum.  The analog switch has an output connected to an amplifier which, in turn, feeds two parallel branches connected as inputs to a differential amplifier, one parallel branch including a high resistance in series with the system input and output and the other parallel branch in-cluding an adjustable voltage divider whereby the input signal levels to the differential amplifier may be made equal for signals originating from the local input and output.  The differential amplifier has an output connected, via an amplitude limited amplifier, to the local input and output.

Abstract: ABSTRACT OF THE DISCLOSURE           A baton twirling doll having a torso, arms, legs, and a head which are all connected so as to simu-late the human body can be connected to a support struc-ture used to provide power to move one or more parts of the body with respect to other parts of the body.  The support structure used includes a wheeled platform and a support member extending from the platform to the torso of the doll.  A mechanical drive is connected to the wheels of the platform so as to be operated when the platform is rolled along a surface.  This drive is con-nected with a motion transmitting structure within the torso of the doll for moving at least one part of the doll relative to the remainder of the doll.  Preferably the doll is constructed so that a hand on one of the arms of the doll is rotated as the arm holding this hand is rotated and so that the legs of the doll are moved to simulate normal leg movement as the wheeled platform is moved along a surface.  With such a structure a baton may be held by the movable hand so that it will rotate to simulate normal baton movement as the platform is moved.

Abstract: REMOVAL OF UNDESIRABLE METAL IONS IN THE CONCENTRATION  OF DILUTE SULFURIC ACID SOLUTIONS CONTAINING IRON(II) SULFATE            ABSTRACT OF THE DISCLOSURE          A process is described for the extensive removal of undesirable metal ions, especially chromium ions, in the reconcentration of dilute iron(II) sulfate containing sulfuric acid solutions by evaporating water and separating iron(II) sulfate wherein the dilute sulfuric acid solution is evaporated up to a content of 60 to 70% by weight H2SO4.       According to the novel feature the dilute sulfuric acid solution or a preconcentrated sulfuric acid solution produced from it, without separation of metal salts, without simultaneous addition of clarified sulfuric acid or sulfuric acid solution is placed continuously into a receiver which contains a sulfuric acid metal salt suspension of which the liquid constituent contains 60 to 70% by weight H2SO4 and that at the same time so much water is evaporated that the sulfuric acid concentration in the liquid part of the metal salt suspension is maintained in the range of 60-70% by weight, and that continuously or at certain intervals a part of the sulfuric acid containing metal salt suspension is removed from the receiver and that the precipitated metal salts are separated.          These solutions are used in the manufacture of titanium dioxide pigments.

Granted: 1981-06-02
Abstract: FLOATING-PRIORITY STORAGE CONTROL FOR PROCESSORS           IN A MULTI-PROCESSOR SYSTEM            ABSTRACT OF THE DISCLOSURE The disclosure describes a floating-priority storage access control arrangement for plural processors to a shared main storage in a multi-processing (MP) system.  The shared main storage logically couples the main storage units provided with each of the processors into a single expanse of real addresses available to each processor.  Exclusive access to the shared storage is given to any processor for as long  as that processor can provide a burst of one or more successive storage requests.  The burst ends when that processor misses a storage cycle by not providing a locally granted request.    The shared storage access is controlled in each processor by means of an MP priority pointer circuit which receives storage requests granted by a local priority circuit in the processor.  The MP priority pointer circuits are interconnected between the processors.   When a burst ends for one processor, another processor having one or more pending storage requests is given priority and begins its burst during the missed cycle, continuing with highest priority until it completes its burst by not having a locally granted request during a cycle.  If no processor makes a request during a storage cycle, and both processors simultaneously make a request during a following cycle, priority for an access burst is given to the processor which last had priority.  Thus, priority flip-flops back and forth between the processors as they respectively access main storage in bursts of requests.
