Abstract: ABSTRACT OF THE DISCLOSURE       A speed switch for a motor has an electrically conductive disc which rotates with the rotor of the motor. A drag member adjacent the disc is mounted for limited pivotal movement and has a permanent magnet linked mag-netically with the disc to cause electromagnetic interaction resulting in a force on the drag member which varies with the speed of rotation of the disc.  A switch is operated by a movement of the drag member to actuate an alarm or to actuate a protective device for the motor.  An improved latching means restrains the drag member from movement until a predetermined rotational speed of the disc is reached.  The latching means has a permanent magnet having a length, height and thickness and is mounted with its height extending in a direction at right angles to the plane of the disc and its thickness extending in a plane parallel to the plane of the disc.  A pair of pole pieces are mounted on each side of and engaging the permanent magnet of the latching means, the pole pieces defining the thickness of the permanent magnet.  The pole pieces project towards the drag member and terminate in a wedge-shaped, flux concentrating configuration.  The drag member has at least three teeth and two of the teeth, which are separated by at least one tooth, are located opposite to and closely spaced from the terminating wedge-shaped ends of the pole pieces.  The pole pieces also extend in a direction opposite the wedge-shaped ends and have inwardly directed arms extending towards one another to form a gap between the. A screw is mounted so that it can be advanced into the gap and withdrawn therefrom to provide a finely adjustable magnetic shunt. The adjustment of the shunt varies, the magnetic latching force and thereby the speed causing actuation of the switch.

Abstract: DIFFERENTIAL PRESSURE GAUGE               Abstract of the Disclosure A differential pressure gauge of the type comprising a controlling magnetic helix device carrying a pressure indicat-ing arm, the position of which is controlled by a magnet mounted on the free end of a cantilevered leaf spring actuated by a pressure diaphragm exposed to differential pressures.  The helix cooperates with a magnet having a planar pole face parallel the axis of the helix and defining a magnetic axis that is normal to and intersects the helix axis.  The gauge housing defines an integral one piece pressure wall that separates the helix from the magnet and defines within the gauge housing pressure cavity an operating space within which the magnet and its supporting leaf spring are mounted and operate.   Between the helix and the magnet the pressure wall is of film dimensions and is contoured to stress in bending. The leaf spring is mounted on a mounting plate disposed within the pressure cavity and engaging the gauge housing only at its rim for stress isolation purposes.  The mounting plate also shiftably mounts an adjustable fulcrum for the leaf spring in the form of a clamp device which may be both positionally adjusted and operated through a common access opening in the housing.  The housing includes a zero datum and a device for setting the indicating arm on the zero datum including an adjustment mechanism coupled to the helix and seated on the housing in alignment with the helix axis.

Abstract: ABSTRACT OF THE DISCLOSURE      A process for the liquefaction of a calcium-containing sub-bituminous or lower rank coal; wherein the coal is first treated to form a water-insoluble thermally stable calcium compound which remains in the pore of the coal on liquefaction, by (i) contacting the coal in particulate form with single compound MX, in an aqueous solution, capable of forming the said water-insoluble, thermally stable calcium compound, M being H+, an ammonium ion or a monovalent or multiple cation selected from the group consisting of the Group IA, IVA, VIB, and VIII metals of the periodic table of the elements, and X being sulfate, carbonate or phosphate, and (ii) maintaining the contact for a period of time sufficient for impregnation of the compound into the pores of the coal; and wherein the thus single compound impregnated coal is then recovered and subjected to coal liquefaction conditions.  On separation of the impregnated particul-ate coal from the solution, the coal can be liquefied in a coal liquefaction reactor (reaction zone) at coal liquefaction conditions without significant formation of vaterite or other forms of calcium carbonate scale on reactor surfaces, auxiliary equipment and the like.
