Abstract: ABSTRACT OF THE DISCLOSURE          Disclosed is a hopper arrangement having a wall structure including a discharge opening and a downwardly swinging hopper door connected to the wall structure for opening and closing the discharge opening.  An improved over-center locking mechanism for the hopper arrangement includes a lock support bracket connected to the wall structure of the hopper with a keeper member located on the door and a latch element having a keeper engaging end portion being pivotally mounted on the bracket adjacent to the opening.  A first link is pivotally connected at one end to the latch element, and a bell crank lever is pivotally mounted on the bracket, the other end of the first link being pivotally connected to the bell crank lever.  Means are connected to the bell crank lever for rotating the same to move the latch element through the first link between locking and unlocking engage-ment relative to the keeper, and the pivotal connection of the first link to the bell crank lever is movable to a latch locking, limiting over-center position relative to the pivotal connection of the first link to the latch element to secure the keeper engaging end portion in locking engagement with the keeper member.

Abstract: Abstract of the Disclosure A radiant tube burner mixes liquid fuel and/or gaseous fuel with air for combustion in a radiant tube to produce a quiet and stable luminous flame through the entire length of the radiant tube.  A flame holding plate is positioned within the radiant tube to define a feed zone and a combustion zone.  A liquid fuel nozzle positioned centrally in the plate directs fuel through the plate and into the combustion zone.  The plate defines a series of apertures circumscribing the nozzle and another passage outward from the series of openings and concentric therewith.  Combustion air is proportioned and admitted to the combustion zone through the series of openings and the passage.  Gaseous fuel may be admitted to the combustion zone through the series of openings.

Abstract: TO ALL WHOM IT MAY CONCERN:          BE IT KNOWN THAT WE, Joseph G. Gorman, John M. Hicks, and Francis A. Holmes, citizens of the United States of America, residing in the cities of Murrysville, Verona, and Monroeville, respectively, County of Westmoreland and Allegheny, State of Pennsylvania, have invented certain new and useful improvements in a REPULSION COIL ACTUATOR FOR HIGH SPEED HIGH POWER CIRCUITS of which the following is the specification.                   Abstract of the Disclosure A pair of pancake-like coils have a coil axis substantially colinear with one coil mounted to a framework and the other coil mounted on a movable member. The coils are wound such that when electrically energized simul-taneously the resulting magnetic fields are in opposition, thereby producing a repelling force therebetween. A spring is disposed between the framework and the movable member to urge the movable member in a sense opposite to the repelling force. A power supply is connected to the coil pair providing for a high initial energy transfer and a lower sustaining energy transfer. A shock absorber is mounted on the framework to arrest the moving member which is set in motion by the repelling force. An armature is attached to the moving memeber which enters the field of a holding coil as the moving member is displaced by the repelling force. When the holding coil is energized with the armature situated therein, the moving member is held against the spring force.

Abstract: ABSTRACT            The presence of antibodies (Ab) and antigens (Ag) in a liquid is detected by mixing the liquid with two different particulate reagents which mutually agglutinate but whose agglutin-ation is inhibited by the particular Ab or Ag under assay.  By detecting the extent of agglutination, the presence or absence of the Ab or Ag can be confirmed.  By measuring the extent of agglutination or non-agglutination quantitatively, an amount of Ab or Ag can be determined.  The particulate reagents prefer-ably comprise latex.

Abstract: ABSTRACT OF THE DISCLOSURE      A technique for heat treating the upper surface of the head of an in situ rail is disclosed.  A car carrying an induction heater followed by an air quencher and then an air and water quencher is passed along the track.  In this way the upper surface of the rail head passes through successive stages of heating from ambient temperature, austenization, hardening, tempering and cooling to ambient temperature thus bringing about desired hardening of the rail head.  The tendency of the rail to bend con-cave upwardly due to this heat treatment is counteracted by applying an upward mechanical force to the rail to tend to bend the rail in the opposite direction i.e. concave downwardly.  The mechanical force is applied by a lifting mechanism carried on the rail car, the lifting mechanism progressively bending the rail simultaneously with the heat treatment.

Abstract: ABSTRACT OF THE DISCLOSURE         A motion transmitting remote control assembly of the type for transmitting forces along a curved path by a flexible motion transmitting core element movably supported within a conduit.  An elongated adjustment member having teeth disposed on the bottom flat side of its irregular shaped cross section is attached to the conduit at one end and extends through a passage-way in a support member adapted for attachment to a support structure.  An L-shaped metal latch member is supported in a guideway in the support member and includes an aperture with a tooth extending along one edge of the aperture for engaging the teeth along the bottom of the adjustment member,  A spring biases the latch member in a direction so that the tooth in the aperture thereof engages the teeth along the adjustment member.  A pair of flanges extend into the passageway of the support member adjacent one end to define a generally T-shaped opening.  The adjustment member has a conforming T-shaped cross section along a length thereof between a circular flange at one end and shoulders disposed along the length of the adjustment member whereby the longitudinal movement of the adjustment member is limited relative to the support member and the adjustment member is also prevented from being removed from the support member after initial assembly.  The assembly allows the length of the conduit to change as the adjustment member moves longitudinally relative to the support member whereby the distance the core element extends from the end of the conduit may be adjusted, the adjustment being affected either manually or automatically in one direction as the teeth ratchet relative to one another.

Abstract: ABSTRACT OF THE DISCLOSURE           A fire rated dry wall ceiling support system having fixed, aligned main beam members spliced together in a manner so as to absorb longitudinal compression, as for example resulting from thermal expansion during a fire. Each main beam includes a web surmounted by a bead with flange portions extending laterally outwardly from the web. Each web end includes a tongue extending axially outwardly for locking engagement with the adjacent beam member web and is so configured that the tongues fold in a longitudinal manner and become laterally displaced out of the normal plane of the tongues when the beam members are longitudinally compressed towards one another. Accord-ingly, the bead means become laterally displaced while may in fact overlap one another in a longitudinal sense. The system further includes support channels disposed trans-versely to the main beam members and engaged therewith. The main beans include pairs of longitudinally spaced slots which receive the ends of the transverse cross channels from both sides of the main beam. The ends of the cross channels are locked in the main beam slots. The slots and cross channel ends are designed to absorb thermal expansion in the transverse cross channels during a fire situation. In addition the cross channels include a horizontal base portion which provides an effective mounting surface for dry wall ceiling panels.
