Abstract: A burner of relatively small BTU rating embodying a multiplicity of jets and particularly suited for burning pulverized coal in small air heater or furnace applications. The subject burner includes a housing having first inlet means formed at one end thereof and outlet means formed at the other end thereof. The first inlet means is connectable to a pipe means through which pulverized coal and primary air are fed from a suitable source thereof to the burner. The burner is further provided with second inlet means, the latter being formed in the burner housing so as to be located therein in close proximity to the aforesaid first inlet means. The second inlet means is connectable to a suitable source of secondary air from where secondary air is fed to the burner.

Abstract: A pulverizing bowl mill embodying improved air deflector means and particularly suited for use in effecting the grinding of material. The subject bowl mill includes a substantially closed separator body in which a grinding table is supported for rotation. A plurality of grinding rolls are supported within the separator body and cooperate with the rotating grinding table to effect the grinding of the material, which is disposed upon the grinding table. Air deflector means corresponding in number to the number of grinding rolls are mounted within the separator body so as to be located in juxtaposed relation to the inner surface of the separator body and so that an air deflector means is interposed between each pair of adjacent grinding rolls. An air supply means suitably formed in the separator body is associated with each of the air deflector means. Each of the air supply means is operable to supply air from an external source thereof therethrough to the interior of the separator body.

Abstract: An apparatus for forcefully feeding cabling in an underwater environment into a container includes a gripper block positionable above the container and an air cylinder for reciprocating the gripper block vertically. Jaws on the gripper block are pivoted to grasp the cabling when the gripper block is reciprocated downwardly but to release the cabling when the block is reciprocated upwardly. This permits forceful feeding of the cabling by mere reciprocation of the gripper block.

Abstract: A plate tube spacer structure operable for concomitantly effecting both the spacing and the supporting of the individual tubes of a tube bundle, the latter commonly constituting one of the components of a conventionally constructed heat exchanger. The subject plate tube spacer structure includes a plurality of elongated plates that are suitably disposed in stacked, spaced relation so as to allow for a layer of tubes to be interposed between each pair of adjacent plates. The plates each have a multiplicity of tube engaging means formed along each longitudinally extending side edge thereof. The multiplicity of tube engaging means are suitably disposed so as to effectively provide each plate with two parallel rows thereof. The arrangement of the rows of tube engaging means of each plate is such that the multiplicity of tube engaging means of one row thereof are aligned with, but face in a direction opposite to that of the multiplicity of tube engaging means of the other row thereof.

Abstract: A Venturi dispersing feeder particularly suited for utilization as part of a flash drying system, and through the operation of which wet material is introduced into a hot gas stream for purposes of effecting the rapid evaporation of the moisture in the material. The subject Venturi dispersing feeder includes a feeder body, which functions as a housing for rotor means. The latter rotor means is equipped with a multiplicity of blade means suitably mounted thereon for rotation therewith. The feeder body further has formed therein inlet means, connectable in fluid flow relation with a source of wet material and operable for feeding the wet material therethrough into the feeder body, and outlet means, connectable in fluid flow relation with a stream of hot gases and operable for discharging the wet material from the feeder body into the stream of hot gases in substantially parallel relation to the path of flow of the latter. The feeder body is suitably supported on a base.

Abstract: A venturi-type rod scrubber for effecting the cleaning of the flue gas produced as a by-product of the combustion process that occurs during the course of the operation of fossil fuel firing steam generators, before the flue gas flows up the exhaust stack and is released to the atmosphere. The subject scrubber includes inlet means through which the flue gas enters the scrubber. A first spray system is suitably mounted in juxtaposed relation to the inlet means so as to be operative to introduce liquid into the stream of flue gas entering the scrubber through the inlet means. In alignment with but in spaced relation to the inlet means, the scrubber is provided with a throat region, i.e., a region of restricted cross-section. A plurality of spaced rows of parallel rods are suitably mounted within the throat region so as to extend substantially perpendicular to the path of flow of the flue gas flowing therethrough.

Abstract: An energy absorbing system, operable as an impact attenuation device for reducing the severity of vehicular collisions, comprising guidance frame means, energy absorbing means and impacting plate means. The guidance frame means, which is operable to secure one end of the energy absorbing system in fixed relation to an object, includes an attachment plate through which the guidance frame means is fastened at one end to the aforesaid object, structural tubing members having one end thereof secured to the attachment plate, first support means operable for supporting the structural tubing members and for securing the other end of the structural tubing members to the aforesaid object, and reinforcing means mounted on the structural tubing members operable to provide additional structural strength to the structural tubing members.
