Abstract: APPARATUS FOR DEFROSTING LOW TEMPERATURE HEAT EXCHANGER       Abstract of the Disclosure An evaporator heat exchanger is disposed within a vertical, rectangular duct.  A heater for defrosting the heat exchanger is disposed beneath the exchanger.   During the defrost cycle heated air rises by convection vertically through the heat exchanger.  The defrost cycle is initiated by sensing the pressure drop across the heat exchanger.  This is done by extending a small diameter pipe through a wall of the duct downstream of the heat exchanger so that an air current is drawn through the pipe during normal operation of the system.   A constant energy output heater heats the air current in the pipe so that the temperature of the heated current remains constant so long as the air volume flowing in the pipe remains constant.  As the pressure drop across the heat exchanger increases as a result of an increasing fro t buildup, relatively more air is drawn through the pipe.  As a result the temperature of the heated air in the pipe decreases.  A control switch is adjusted so that it initiates the defrost cycle whenever the air current temperature reduction in the pipe reaches a predetermined value.

Abstract: Abstract of the Disclosure A fuel injection arrangement for an internal combustion engine having a cylinder head comprises a fuel injection device located against a step in a borein the cylinder head.          The device includes a valve member which is spring loaded to a closed position but which is opened by fuel under pressure which flows through an inlet.  The device is retained against the step in the bore by a member having a head and a shank portion the latter being in screw thread enlargement in the bore.  The shank portion defines a surface to engage an enlarge-ment on the fuel supply pipe and the enlargement also engages surface formed on the device adjacent the inlet.  The member therefore serves to retain the pipe in sealing engagement with the inlet and also retains the device in position within the bore.

Abstract: ABSTRACT OF THE DISCLOSURE            A method and apparatus for forming a heated end of a plastic pipe into a bell having a sealing groove therein arranged to receive a seal so that it may be sealingly joined with a plain end of a second pipe inserted therein.  The apparatus comprises a mandrel base rigidly secured to a mandrel core having annular grooves formed thereabout communicating with a vacuum source through a passage formed in the core and base. A mandrel shell comprising four separable segments is secured on the core.  The mandrel shell has a plurality of apertures formed therein communicating with the annular groove on the core such that a vacuum may be drawn through the apertures.  A heated plastic pipe is forced over the mandrel shell until it engages a tapered shoulder formed on the mandrel base, thus forming a seal between the end of the pipe and the base.  A vacuum is drawn on the cavity formed between the plastic pipe and the mandrel shell thus drawing the plastic pipe to the shell, forming an annular internal groove in the pipe.  Segments of the mandrel shell are removed from the end of the pipe after withdrawing the mandrel core therefrom.

Abstract: ABSTRACT OF THE DISCLOSURE     A snap roller utilized as a snatch lock employs a pulley and a rod fabricated from a wire-like spring material to which the pulley is journalled.  The rod has n portion of its length, located substantially in the central regions thereof to which the pulley is journalled.  A pair of portions of the length of the wire-like rod extends radially outwardly from the longitud-inal axis of the pulley in a direction substantially parallel to one another.  The ends of the wire-like rod are formed into oppositely directed hooks such that each of the distal ends approach, and if desired contact the opposed length of the pair of portions of the wire-like rod.  In use, a rope or line may be passed between the hook-like ends so as to engage a groove in the pulley due to the fact that each hook-like end resides in planes that are skew to one another allowing the distal ends of the hooks to be forced outwardly from the opposed one of the pair of portions of the wire-like rod.  In similar fashion an eye-hook or other bight-like element, such as an eye-hook or spring bight may be engaged within the opening defined by the hooks and the pair of portions of the length of the wire-like rod and the pulley, by passing the bight in between the hook-like ends until the portions of the bight pass the distal ends of the hook.  A twisting motion to the bight or the wire-like rod enables the bight to reside capturing the hooks.  The line or the bight way be disengaged by reversing the pro-cedure utilized to capture these elements to the snatch block.          An alternate embodiment utilizes a hook-like excursion on the hook-like ends of the wire-like rod which engage portions of the lengths of the wire-like rod in a locking like arrangement, which enhance the ability of the rod to carry great forces applied to the line or the eye hook carried thereby.     -ii-
