摘要： A true union ball valve comprising a body having a continuous axial chamber; a rotatable ball in the center of the chamber; a cylindrical seal carrier on each side of the ball, the diameter of the inner portion of each seal carrier being approximately equal to the diameter of the chamber and the diameter of the outer portion of each seal carrier being less than the diameter of the chamber to define an abutment in the outer surface of each seal carrier and a radial space between the outer portion of each seal carrier and the body; the body having an internal groove therein, perpendicular to the axis thereof, surrounding each radial space; a split locking ring positioned around each seal carrier, in the radial spaces; and a cam ring extendable into each radial space, from the ends of the valve body, between the seal carriers and the locking rings, for expanding the locking rings into the grooves in the valve body thereby wedging the locking rings between the grooves in the body and the abutments on the seal carriers to lock the seal carriers in the body.

摘要： A single device for driving a pair of floppy discs, preferably the smaller mini floppy discs, is disclosed herein and identified as a dual floppy disc machine. A drive motor is coupled to a pair of rotatable spindles mounted side by side. The spindles receive respective floppy discs thereon, and are driven at a speed not to exceed 50 rpm, much lower than the speed of conventional floppy disc machines. A pair of read/write heads are provided which have a capacity of reading no more than 20,000 bits per second, again well below conventional rates but sufficient for the speeds used in the present invention. A single carriage has both read/write heads mounted thereon in spaced relationship, and is moveable along an axis bisecting a line connecting the centers of the spindles. As a result, the read/write heads are moveable in unison radially relative to the respective spindles. A stepping motor is coupled to the carriage to move the carriage along its axis. The pair of floppy discs are clamped to their respective spindles, and the read/write heads are biased against the respective discs so that both discs can be utilized.

摘要翻译： 本文公开了用于驱动一对软盘，优选较小的小型软盘的单个设备，并被标识为双软盘机。 驱动马达与并排安装的一对可旋转主轴连接。 主轴在其上接收各自的软盘，并以不超过50rpm的速度驱动，远低于常规软盘机的速度。 提供了一对读/写头，其具有每秒读取不超过20,000位的能力，这仍然远低于常规速率，但对于本发明中使用的速度是足够的。 单个托架具有以间隔的关系安装在其上的读/写头，并且可沿着将连接心轴中心的线平分的轴线移动。 结果，读/写头可以相对于相应的主轴径向地一体地移动。 步进电机联接到滑架以沿其轴线移动滑架。 一对软盘被夹紧到它们各自的主轴上，并且读/写头被偏压到相应的盘上，从而可以利用两个盘。
