Abstract: Elrick Case 1 SLURRY CAST DOUBLE BASE PROPELLANTS      Abstract of the Disclosure A slurry casting process is described capable of producing crosslinked double base propellant having improved burning rates and high specific impulse.  Such propellants can be formulated to be smokeless.  Improved burning rates are achieved by incorporating into a slurry of double base composition, casting powder granules containing 20% to 75% by weight of small particle ammonium perchlorate.  The casting powder granules substantially retain their identity in the cured propellant matrix.  The casting powder granules have a high burning rate and are uniformly distributed throughout the propellant.  The granules are responsible for increasing the burning rate of the entire crosslinked double base propellant composition of the invention.

Abstract: ABSTRACT OF THE DISCLOSURE         An internal combustion engine is illustrated having an engine block, a cylinder located in the engine block, and a cylinder head defining an end wall of the cylinder.  A piston is housed in the cylinder and defines with the cylinder and the cylinder head a combustion space adapted to receive a mixture of fuel and air therein.  The piston is reciprocably movable toward the cylinder head to compress a fuel mixture in the cylinder and movable away from the cylinder head, the piston engaging one side of the cylinder as the piston moves toward the cylinder and engaging an opposite side of the cylinder as the piston moves away from the cylinder head.  The piston includes an annular groove, and the piston ring is housed in the annular groove, the piston ring including opposite ends being spaced apart and forming a gap. The piston ring is positioned with the gap adjacent that side of the cylinder engaged by the piston as the piston moves away from the cylinder head such that the gap provides for pressure release from the combustion chamber during movement of the piston toward the cylinder head.

Abstract: ABSTRACT        The novel esophageal-endotracheal airway has a shorter outer tube and a longer inner tube.  The airway is adapted to become inserted into either the trachea or into the esophagus.  Each tube carries an expandable member on its outer wall and near its distal end.  The outer wall of the inner tube and the inner wall of the outer tube form an annular passageway therebetween.  Suction tubes can be inserted through this passageway for pumping out either the stomach or the lungs.  This annular passageway cannot become totally occluded by any tissue from an adjacent body channel because the inner tube, as it exits from the annular passage-way, acts to prevent tissue encroachment.  By having the longer tube inside the shorter tube, which terminates in the posterior pharynx, a suction tube can be advanced through the annular passageway exiting at the outlet of the shorter tube in an anatomical position to be advanced directly into the esophagus without any interruption of artifical respiration

Each leaf spring assembly (28, 30) is secured between one of the outer equalizing beams (18) and the inner equalizing beam (20).  The leaf spring assemblies (28, 30) include an axle connection (34) for supporting an axle (14) and a ground-engaging wheel.  Load equalization is enhanced by radius rods (80, 100) which extend between one of the axles (14) and one of the trunnion tubes (46).
