    Abstract: An extruder shut-off nozzle with a valve body and orifice having a plurality of metering ports feeding the nozzle passageway. A closure member captive in the body of the torpedo capable of being moved by compressed air after an injection cycle to seal the extruder orifice and prevent drooling of plasticized material at the nozzle when starting the next mold cycle. A suck-back action of the extruder screw at completion of the injection cycle will cause melt normally in the nozzle to be pulled back into the extruder chamber, thereby preventing drooling of plastic from the nozzle when the piston is in the shut-off position.

    Abstract translation: 具有阀体和孔口的挤出机关闭喷嘴具有供给喷嘴通道的多个计量端口。 鱼雷体内的封闭构件能够在注射循环之后被压缩空气移动，以密封挤压孔，并防止在启动下一个模具周期时喷嘴处的塑化材料流出。 在注射循环完成时，挤出机螺杆的回吸作用将导致喷嘴中的熔体通常被拉回到挤出机室中，从而当活塞处于关闭位置时防止塑料从喷嘴流出。

    Abstract: Apparatus for finishing the inner surface of a workpiece having an epitrochoidal configuration as, for example, the combustion chamber casting of a rotary internal combustion engine. A special mounting assembly adapted for eccentric rotation about a mandrel includes a tool holder for supporting tools which operate on the epitrochoid-shaped inner surface of the workpiece. Drive means for the mounting assembly include a rotatable spindle having a cam fixed thereon which urges the mounting assembly and tool holder to orbit about the mandrel. A fixed gear on the mandrel and a ring gear on the mounting assembly control the rotation in a timed relationship as the ring gear is urged to orbit about the fixed gear to cause a tool carried on the tool holder to describe an epitrochoidal path and thereby follow along the inner surface of the workpiece.

    Abstract: A controlled friction tape roller for a tape transport system for reel to reel operations is described. A controlled friction tape roller is arranged adjacent a tape reel to introduce a high tension in the tape extending between the reel and the controlled friction roller to allow the tape to be more tightly wound or packed on the reel.

    Abstract: A horizontal spindle machine that is constructed and arranged to carry out a variety of machining operations such as milling, drilling, boring, tapping and the like, and which includes an automatic tool changing means for transferring tools in a predetermined sequence between a tool storage conveyor and a tool spindle. The machine includes a work table mounted on a rotary index table that is carried on two movable, perpendicularly disposed members to provide movement of the work table along the ''''X'''' and ''''Z'''' axes. The tool spindle is slidably mounted on the front side of a rigid column for movement along the ''''Y'''' axis. The tool storage conveyor is mounted on the left side of the rigid column on the operator''s side of the machine. The tool changing means includes a transfer arm for transferring tools between the storage conveyor and a 90* tool turn around means, and a second transfer arm for transferring tools between the 90* turn around means and the tool spindle.
