Abstract: POWER OPERATED SURFBOARD                    ABSTRACT OF THE DISCLOSURE           A power operated surfboard which has a raised rear hollow portion at the rear in which is disposed an impeller housing having an impeller therein and a water discharge pas-sage extending rearwardly from the housing.   An internal combustion engine is supported above the impeller housing and has a short vertical axis connected to the impeller which rotates about a vertical axis.  Surrounding the impeller housing is an exhaust gas housing which communicates with the exhaust gas passage of the engine and with a discharge chamber beneath the floor of the surfboard.  The exhaust gas housing is gas tight and provides a gas cushion which retards the entrance of water through the discharge chamber into the exhaust passage of the engine, when the surfboard is not being operated.  This is aided by a flexible valve disposed at the discharge outlet of the discharge chamber to retard the entrance of water into the discharge chamber. Associated with the exhaust gas discharge chamber and forming a part of a two part chamber is a water inlet chamber which communicates with the intake of the impeller through the floor of the boat and extends over the opening to the impeller to prevent accidental contact with the rotating impeller either by an occupant or by some foreign object.         A belly pan has a bottom wall disposed between the engine and the impeller housing and surrounds the engine to form an engine compartment.  Disposed at the bottom of the engine compartment is a one way valve which permits draining of water or fuel from the belly pan but hinders the access of water into the interior of the belly pan.

Abstract: ABSTRACT OF THE DISCLOSURE         A process is disclosed for producing an air jet textured polyester yarn having a low dry heat shrinkage. The process comprises the steps of:  (a) cold drawing a spin-oriented polyester yarn at a draw ratio of from 1.3 to 2.0; (b) preheating the drawn yarn at substantially constant length; (c) feeding the yarn to an air jet at a 10% to 40% overfeed; (d) jet-texturing the yarn with the air jet; (e) drawing the jet-textured yarn at a draw ratio of 1.04 to 1.12; and (f) winding up the resulting air jet-textured yarn.  In an embodiment of the process a step of post-heating the jet-textured yarn is included between step (e) and step (f) in order to reduce the size of the surface loops and to improve the stability of the jet-textured yarn.
