摘要： A rotating disc has perforated seed pockets which pick up individual kernels of seed from a cavity of a planter housing. Bulk seed flows by gravity from a hopper to the cavity which is pressurized by a blower. As the disc rotates through the cavity, air flowing through the perforated pockets will move the seeds into the pockets and hold them there as the disc rotates to bring the seed carrying pockets into axially confronting relation with a flat sealing surface. The flat sealing surface holds the seed in the pockets as the disc rotates further to a position wherein the pockets are exposed to an open bottom area of the housing at which point the seeds are free to fall by gravity into the soil.

摘要： A breakaway mechanism for supporting a non-contact tool to protect the tool in the event of an inadvertent collision includes a non-redundant locating system to establish precise tool repositioning and a magnetic holding device to retain the tool in its operative attached position. The non-redundant locating system assures initial mounting and relocating after breakaway which is immune from inaccuracies resulting from manufacturing tolerances and the magnetic mounting device permits breakaway separation free from any mechanical restraint. The invention is particularly suitable for use on an automatic metal cutting torch, but may be applied to many non-contact tools which are positioned and operated by computer or robotic control.

摘要： A vertical spindle numerically controlled machining center includes a stationary bed or base on which a workpiece holding table is slidably mounted for movement along a first axis. A vertically extending upright or column, having a vertically reciprocal spindlehead slidably mounted thereon, is slidably mounted on the bed for movement along a second axis perpendicular to the first axis so that the spindlehead overlies a portion of the table. Within the upright is a recess adjacent to the bed. A tool storage magazine is located in the recess and is slidably mounted on the bed for movement through the recess along an axis parallel to the second axis. During a tool change cycle, the toolholder then held in the spindle is returned to the tool storage magazine by first moving the spindlehead to the ready position and then moving the tool storage drum toward the spindlehead to engage the tool then held in the spindle. To provide the spindle with a new tool, the spindlehead is first moved upwardly to clear the toolholder shank and then the tool storage drum is indexed to position a new tool directly beneath the spindle so that the spindle can engage the tool when the spindlehead is moved downwardly to the ready position.
摘要翻译：垂直主轴数控加工中心包括固定床或基座，工件保持台可滑动地安装在固定床或基座上以便沿着第一轴线移动。具有可滑动地安装在其上的垂直往复主轴头的垂直延伸的立柱或立柱可滑动地安装在床上，用于沿着垂直于第一轴线的第二轴线移动，使得主轴头位于台的一部分上。在立柱内是与床相邻的凹槽。工具存储盒位于凹部中，并且可滑动地安装在床上，用于沿着平行于第二轴的轴线移动通过凹部。在刀具更换循环期间，通过首先将主轴头移动到就绪位置，然后将工具存储鼓移动到主轴头，然后将夹持在主轴中的刀架返回到刀具存储仓库，从而将刀具保持在主轴中。为了向主轴提供一个新的工具，主轴首先向上移动以清除刀柄，然后将工具存储滚筒转位，以将新刀具定位在主轴的正下方，以便当主轴头移动时主轴可以与刀具接合向下到准备位置。
