摘要： Adsorbed gaseous species and elements in a carbon (C) powder and a graphite crucible are reduced by way of a vacuum and an elevated temperature sufficient to cause reduction. A wall and at least one end of an interior of the crucible is lined with C powder purified in the above manner. An Si+C mixture is formed with C powder purified in the above manner and Si powder or granules. The lined crucible is charged with the Si+C mixture. Adsorbed gaseous species and elements are reduced from the Si+C mixture and the crucible by way of a vacuum and an elevated temperature that is sufficient to cause reduction but which does not exceed the melting point of Si. Thereafter, by way of a vacuum and an elevated temperature, the Si+C mixture is caused to react and form polycrystalline SiC.

摘要： A generally rectangular open topped vessel with vertical walls around the periphery of a floor consisting of two integrally formed levels, the lower level being at one end providing a footwell and having a drain therein. Near the end of one side wall, in the area where the footwell is located, is a door opening. This door opening has a ferromagnetic faced door stop around the edge. A door is hingedly attached to the edge of the opening such that it swings horizontally inward towards the nearest adjacent end wall. The door has a flange along its two vertical edges and along its bottom horizontal edge. Mounted concentrically on the flange are two magnetic gaskets such that when the door is closed the gakets force a water tight seal with the ferromagnetic plate on the door stop. A second drain is located in the surface of the bottom door stop such that when the door is closed water in the vessel cannot reach the drain due to the sealing of the outer gasket. With the door open water will go down this drain before it reaches the door opening.
摘要翻译： 一个大致矩形的敞开的顶部容器，其具有围绕由两个整体形成的水平面组成的地板的周边的垂直壁，下部水平面在一端提供一个脚部空间并且在其中具有排水口。 靠近一侧墙的尽头，在脚部井位于的区域，是一个开门。 这个门开口在边缘周围有一个铁磁面门。 门铰接地连接到开口的边缘，使得其向着最靠近的相邻端壁的水平方向摆动。 门沿着其两个垂直边缘并沿其底部水平边缘具有凸缘。 安装在法兰上的两个磁性垫片是两个磁性垫片，这样当门关闭时，套筒会与门锁上的铁磁板一起进行防水密封。 第二排水管位于底门挡板的表面，使得当门关闭时，由于外垫圈的密封，容器内的水不能到达排水管。 在开门开门之前，开门的水将会下降。

摘要： A motorized treadmill exercising device comprising a generally planar frame equipped with a planar slider bed and head and tail rollers journalled respectively at the head and tail ends of the frame, over which an endless plastic belt is trained. The treadmill at its head end is equipped with a cross member that pivotally mounts a motor assembly including an electric drive motor and shaft driven by same that is keyed to a variable speed pulley aligned with an ordinary fixed speed pulley keyed to the treadmill belt head roller, and between which a drive pulley belt of the V type is tensioned by the biasing action of the variable speed pulley that subjects the motor assembly to uniform spring biasing action about the pivotal mounting of the motor assembly for tensioning the pulley belt into drive transmitting relation with the respective pulleys, and with the treadmill apparatus including hand hold railing on either side of same between which the treadmill user exercises, with one of the hand rails having mounted on same and connected with the treadmill drive motor assembly for pivoting same, a control mechanism that is adapted for hand actuation by the treadmill user when using the treadmill, for changing of the tensioning of the pulley belt, and the adjustment of the variable speed pulley, for convenient infinitely variable speed changing of this treadmill belt between its maximum and minimum speeds provided by the treadmill apparatus involved and protection of the drive equipment against damage.
