Abstract: METHOD AND APPARATUS FOR MAKING HIGH PURITY AMORPHOUS SILICA FIBERS     Abstract of the Disclosure A method and apparatus are disclosed for producing amorphous silica fibers having excellent resistance to devitrification at temperatures up to 2500°F by leaching glass fibers.          The method involves controlling the non-silica ingredients in the starting glass fibers and periodically gently stirring the glass fibers during leaching.          The apparatus comprises a perforated basket resting in the upper half of a leaching tank.  An acid solution is added to the tank through a rotating spray arm until the solution just barely covers a fibrous mass of loose sodium silicate fibers which are disposed in the perforated basket. A mechanical stirrer or agitator is provided proximate the top surface of the fibrous mass in addition to or in combination with the acid solution rotating spray arm. The periodic stirring and fluffing of the fibrous mass during the leaching cycle and a subsequent rinsing operation produces the uniformity desired  in the leached fibers.

Abstract: A B S T R A C T     A process for making citraconic anhydride by the vapor phase oxidation of mesityl oxide at a tempera-ture of 200-500°C.  Air or pure oxygen can be used for the oxidation, wherein the molar ratio of oxygen to mesityl oxide is 10:1 to 100:1.  Preferred catalysts are vanadium oxide, vanadate salts and vanadyl salts.  If desired, the catalyst can be deposited on a suitable support such as alumina, silica, pumice or silicon carbide.  Small amounts of maleic anhydride are normally produced in the reaction and can be separated from the reaction product, if desired.

Abstract: S P E C I F I C A T I O N     LINKAGE FOR CONTROLLING TWO                      INDEPENDENT POWER UNITS     ABSTRACT OF THE DISCLOSURE A linkage is provided to simultaneously control two independent hydraulic drive motors for a vehicle, each having a control arm movable between a high speed position and a low speed position.  The linkage comprises a control shaft having a pair of spaced apart cam elements mounted thereon which engage each of the control arms to pivot them in opposite directions as the shaft is rotated.  The linkage is also movable in an axial direction which thereby insures that both control arms reach corresponding high or low speed positions.  For instance, if one control arm should reach a respective position prior to the time the other control arm reaches its corresponding position, further rotation of the shaft and cam elements therewith also results in axial movement thereof thus insuring that such other control arm reaches its corresponding position.

Abstract: ABSTRACT OF THE DISCLOSURE              A differential transformer having a core of low perme-ability ferromagnetic material, a pair of identical primary windings and a secondary winding of relatively few turns capable of producing a large voltage output for a small magnitude ground fault current. A cross-field winding is utilized to periodically saturate a portion of the flux path in the transformer core to produce sudden changes in magnetic flux, which flux changes vary in magnitude proportional to the amount of fault current.  During the time interval when the cross-field portion of the sensor is not saturated by a pulse of sampling current, a second pulse of current is introduced into the sensor secondary winding for detecting a grounded neutral wire by sensing the output voltage produced in response thereto.

Abstract: APPLIANCE TIMER                  ABSTRACT OF THE DISCLOSURE    An appliance timer including an axially narrow pro-gram wheel or disc mounted for rotation and having a plu-rality of grooves formed in its axially facing surfaces, the grooves being concentric with the wheel's axis.  The bottoms of the grooves define the program controlling sur-faces.  A plurality of double-pole, single-throw switches are mounted in the appliance timer housing, the distal end of the throw of each of the switches being formed to pro-vide a follower which rides in one of said grooves against its program controlling surface, thereby controlling the switch.  The switches in turn control the various appliance cycle portions.  In the preferred embodiment, the program wheel is driven from a constant speed motor through an es-capement mechanism.  The escapement mechanism includes a cylindrically shaped driving member which is concentric with the program wheel axis.  One or more cam lobes pro-viding camming surfaces are formed on the interior cylin-drical wall of the driving member.  A ratchet wheel is disposed for rotation on the program wheel drive shaft.          A pawl having a ratchet wheel engaging member at one end and a follower at the other end is actuated by the camming surfaces on the driving member to disengage the pawl from the ratchet wheel, to cause the pawl to move a predetermined distance in a first direction, re-engage the ratchet wheel, and then return the same distance in the opposite direction to advance the ratchet wheel, and an output shaft to which the ratchet wheel is drivingly connected, in response to rotation of the driving member.

Abstract: A B S T R A C T         A static circuit arrangement for the production of three-phase current, comprising a plurality of waveform generating stages arranged in cascade.  Each stage is adapted to provide either a positive or negative voltage.         The stages are controlled so that in the case of increasing a voltage from zero to a maximum (either positive or negative) the first stage is rendered conductive, then the second, third and so on until the nth stage is conductive together with all the other stages, and in the case of a voltage decreasing from a maximum to zero all the stages are conductive and these are rendered non-conductive one at a time starting with the nth, then (n-1)th and so on until the first stage is rendered non-conductive.         The first stage comprises three amplifier circuits, one for each phase, whereas the second and successive stages each comprise a single circuit which is common for all phases of a voltage to be generated.  Each circuit of the first stage has its own phase load, e.g. a motor winding connected thereto.

Abstract: SELF-UNLOADING SHIP WITH TWO TUNNEL BELTS           AND A CENTRAL RECLAIMER                  ABSTRACT OF THE DISCLOSURE         A self-unloading ship includes two longitudinal tunnels with conveyor belts below two rows of hoppers at the bottom of the holds which extend nearly from one end of the ship to the other for unloading bulk material such as coal, iron ore gypsum or the like.  During unloading, the hopper gates are opened and the bulk material on the starboard and port sides of the cargo holds flows by gravity through the open hoppers onto the tunnel belts.  A central ridge of bulk material remaining on the bottom floor of the holds between the two rows of hoppers is moved to the hoppers by a wheeled reclaimer having oppositely pitched augers which split the central ridge of bulk material, moving one-half to the starboard row of hoppers and one-half to the port row of hoppers.  The reclaimer includes a power driven, endless chain harrow which drags down the central ridge of bulk material to prevent avalanching and an endless belt brush for cleaning the hold floors between the two rows of hoppers.  The forward hold of the ship extends into the area of the bow having diminished width with the outboard walls of the forward hold converging to a reduced distance therebetween.  Such ship construction (which affords increased capacity) is possible because of the use of two laterally spaced rows of hoppers and a central reclaimer for clearing bulk material from the floor between the hoppers.          The inclined surfaces of the holds and their hoppers may be lined with a smooth plastic or similar material to improve the gravity flow of bulk material from the holds.
