Abstract: Abstract of the Disclosure This is an improved smokeless flare powered by air supply to the burner at substantial velocity, The flare includes an air flow-operated tamper for the purpose of preventing the back flow of flame ant hot gases under adverse wind conditions.  The damper consists of two semi-circular plates which are hinged along the diameter of the air supply pipe and are held in a closed (transverse) position by means of tension springs.  Another feature of this flare is that in the sectors between the spider arms of the burner there are baffles which are triangular in shape and have substantial longitudinal dimension.  There are narrow passages between the baffles and each of the adjacent spider arms so that the air flow from the blower must pass through these restricted passages and therefore will move at a higher velocity.  A third feature involves openings through the side wall of the air flow pipe opposite the baffles so that there is induced flow of air through these openings into the baffle space and up through the triangular wall of the baffle to prevent accumulation of soot.

Title: Volatile liquid supply equipment and processes and apparatus for introducing volatile cross-linking agents into polyolefin compounds and for the extrusion of cross-linkage polyolefin compounds

Abstract: Abstract of the Disclosure In accordance with an exemplary embodiment of the instant invention,  a volatile cross-linking agent such as liquid peroxide is introduced, at ambient temperature and under atmospheric pressure directly into the input of an extruder at the same pressure as a poly-olefin compound to be cross-linked. The resulting compounds are put under pressure within the extruder as the temperature increases so that the mixture reaches its definitive shape at the extruder output and may be fed directly into a hot cross-linking enclosure which is maintained under pressure. The peroxide is thus incorporated in a single operation permitting complete control of the ingredients mix-ed and allowing perfect homogenization of the mixture while defusion and consequent loss of the highly volatile peroxide are avoided.      The system for introducing the highly volatile cross-linking agent includes a peroxide storage tank, a filling pump, a feed vessel, an incremental feed pump with a pressure meter, a flow meter and numerous safety features. These elements control the flow, temperature and ambient conditions of the cross-linking agent feed system within a controlled environment to ensure the safe and precise handling of a highly volatile liquid while at the same time controlling the feeding of the liquid as a function of the material processed by the extruder so that the percentage of the cross-linking agent inserted at the input to the extruder remains at a constant, predetermined percentage, regardless of extruder speed variations. Additionally, various addi-tives which are soluble in the volatile cross-linking agent may be introduced within the feed system therefor in sufficient amounts for effecting protection of the resulting polymer without altering the efficiency of the feed system or that of the additive so that the entire process may be carried out at the processing site without initial preparation of various mixtures  to be further processed.

Abstract: ABSTRACT OF THE DISCLOSURE             A method is disclosed of making sintered parts with cryogenically produced powder derived from scrap metal, such as machine turnings.  The scrap metal is subjected to two impacting operations (such as by use or a ball milling machine).          The first operation is carries out with the use of a refrigerating agent (to lower the temperature of the scrap metal below its ductile-brittle transition temperature) thereby resulting in comminution of the scrap to a cryogenic powder.          The second impacting operation is carried out at ambient temperature conditions utilizing two groups of milling elements, one which impacts cold work to at least a portion. of the cryogenic powder and another group which simultaneously mechanically impacts copper to substantially each particle of said cryogenic powder to form a continuous copper envelope thereabout.  The coated cryogenic powder is then compacted and sintered; the sintered product may be subjected to hardening or tempering treatments if desired.

Abstract: ABSTRACT OF THE DISCLOSURE                 A pressing tool for electrical connectors, or the like, including an elongated housing, an anvil carried by the housing adjacent one end thereof, a presser carried by and movable relative to the housing toward and away from the anvil along a presser path perpendicular to the anvil, an elongated handle extending longitudinally of the housing and accessible from the exterior thereof, means connecting the handle to the housing for producing longitudinal movement of the handle relative to the housing in response to lateral movement of the handle relative to the housing, and means for converting such longitudinal movement of the handle relative to the housing into movement of the presser along the presser path toward the anvil.  Reversed movement of the handle is prevented until the presser has been moved a predetermined distance toward the anvil.  A track means conveys successive connectors to be pressed into a pressing chamber which is so inclined relative to the track means that each connector is separated from the succeeding connector.          An interceptor means prevents movement of a connector from the track means into the pressing chamber when intermittent operation is desired.  The anvil is cantilevered toward the track means and the pressing chamber is open sided for easy access to a connector in the pressing chamber.  With this construction, several different types of connectors may be processed with left handed and right handed orientations, without any need for attachments, or interchangeable parts.
