摘要： The present invention, hereinafter referred to as the Basketball Return System employs a frame and net to catch the ball, whether made or missed, and funnels the ball directly back to the shooter at the free-throw line. The Basketball Return System consists of a frame to be clamped onto the basketball goal's backboard, and a net which hangs down from the frame and trails out toward the free-throw line. The frame is clamped to the bottom edge of the backboard, and extends downward slightly below the bottom of the backboard, tapering inward from the sides. The frame also extends upward on each side of the basket, with a forward-projecting fin or wall on each side of the hoop, and a shelf-like crosspiece projection above the hoop. From the bottom of the Basketball Return System frame is hung a net, similar in weave to the basketball net, and this net tapers inward from the frame and is laid out in a narrowing drape toward the free-throw line. The Basketball Return System prevents errant free-throw shots from rebounding outward from the goal and returns both made and missed shots to the feet of the player at the free-throw line.

摘要翻译： 本发明以下称为篮球返回系统，采用框架和网来抓球，无论是制造还是丢失，并且在罚球线上将球直接返回射手。 篮球返回系统包括一个被夹在篮球场的篮板上的框架，一个从框架上挂起的网路向罚球线移动。 框架被夹紧到背板的底部边缘，并且向下稍微向下延伸到背板的底部，从侧面向内逐渐变细。 框架还在篮子的每一侧向上延伸，在箍的每一侧上具有向前突出的翅片或壁，以及在箍上方的搁板状横档突起。 从篮球返回系统框架的底部挂起一个网，类似于编织到篮网，这个网从框架向内逐渐变细，并以狭窄的悬垂方式摆放在罚球线上。 篮球返回系统可以防止错误的罚球从球门外向外反弹，并将罚球命中的射门和射门返回球员脚下。

摘要： A fuel inlet system (12) for an internal combustion engine (10) comprises a heat exchanger (22), heated by engine exhaust gases, to preheat air being supplied to a carburetor (14). The air is introduced into the carburetor (14) at a temperature of between about 375.degree. to 400.degree. F. The carburetor (14) has an annular heating chamber (122) in which the heated air is circulated. A fuel inlet conduit (63) is in thermal contact with the heated air in the heating chamber (122) to preheat the fuel. The air and fuel is mixed in two stages, the first being during travel along a conduit (144) and the second in a mixing chamber (170) in the carburetor (14). The carburetor (14) includes a valve (148) for restricting the amount of air flowing to the mixing chamber (170). The fuel inlet system (12) further comprises means (20) for adding water to the air/fuel mixture.
