摘要： Each of a plurality of passages in a fixture has a piston movable therein and cooperating with a collet therein to simultaneously move each collet to its workpiece retaining position and to release each collet from its workpiece retaining position. A recess in the bottom of the fixture supports a locking nut for each passage. Each locking nut has a circular passage extending therethrough to receive an end of the collet having threads on its outer surface. The circular passage has threads of the same pitch but the threads have an interrupted portion in the circumferential and axial directions. The locking nut has a first portion movable relative to a second portion to take up the pitch clearance in the threads on the collet due to the interrupted portion of threads in the circular passage to prevent rotation of the collet prior to the piston moving the collet to its workpiece retaining position.
摘要翻译： 夹具中的多个通道中的每一个具有可在其中移动的活塞并与其中的夹头配合以同时将每个夹头移动到其工件保持位置并且将每个夹头从其工件保持位置释放。 固定装置底部的凹槽支撑每个通道的锁紧螺母。 每个锁定螺母具有穿过其延伸的圆形通道，以接收在其外表面上具有螺纹的夹头的一端。 圆形通道具有相同螺距的螺纹，但是螺纹在周向和轴向上具有中断部分。 锁定螺母具有可相对于第二部分移动的第一部分，以便由于圆形通道中的螺纹的中断部分而卷绕在夹头上的螺纹中的间距间隙，以在活塞将夹头移动之前防止夹头旋转 其工件保持位置。

摘要： A bar feeder support has two longitudinally spaced swivel mounts for supporting longitudinally spaced portions of a cylindrical body for both sliding and swivel movement. The cylindrical body supports a feed tube for feeding a bar stock to a lathe. The front swivel mount, which is closest to the lathe, also has a clamp arrangement for clamping the cylindrical body against movement. The swivel mounts allow the cylindrical body to swivel sufficiently to slide from a position in which its longitudinal axis is aligned with an axis of a spindle of the lathe and an access position in which a new bar stock may be disposed in the feed tube, the feed tube may be removed from the cylindrical body, and another feed tube may be loaded into the cylindrical body.
摘要翻译： 一个送料器支架具有两个纵向间隔开的旋转安装座，用于支撑圆柱形主体的纵向隔开的部分，用于滑动和旋转运动。 圆柱形主体支撑用于将条形坯料供给车床的进料管。 最靠近车床的前旋转安装座还具有用于夹紧圆柱体抵抗运动的夹紧装置。 旋转安装件允许圆柱体充分旋转以从其纵向轴线与车床的心轴的轴线对准的位置以及可以在进给管中设置新的棒料的进入位置滑动， 进料管可以从圆柱体移除，另一个进料管可以装载到圆柱体中。

摘要： A plurality of female couplers and a plurality of male couplers are simultaneously connected or disconnected by simultaneously applying an axial force along the aligned axes of each pair of female and male couplers. A pushing force is employed for connecting, and a pulling force is utilized for disconnecting. The forces may be employed manually, pneumatically, or hydraulically.

摘要： Disclosed are systems and methods relating to an automated or semi-automated arrangement of modules that helps gather, process, display, and coordinate meetings among matches based on a set of predetermined and crowd-sourced traits, values, interests, preferences and activities. Such systems of integrated modules in certain embodiments may be used to rank matches in a variety of applications and situations where participants are identified through tailored criteria that organizers, participants and sponsors determine to be most valuable. Embodiments of the present invention may offer advantages and improvements over prior computer and traditional networking and matching systems because they may provide interactive modules that automatically or semi-automatically combine human expertise with automated data management based on the expertise of an event organizer's event-management strategies with real-time and automated data management.

摘要： An actual pressure of a fluid having an ambient pressure as part thereof is sensed by a sensor. When the actual pressure decreases below a predetermined pressure, a signal is produced. If desired, the sensor may cause production of the signal when the actual pressure of the fluid exceeds a predetermined pressure.

摘要： A two-stage reciprocating compressor has its low pressure stage inlet connected to a source of gas generating a varying volume of gas. When the supply of gas generated is reduced to an extent that the pressure at the low pressure stage inlet decreases below a predetermined pressure, the compressor is unloaded at either the discharge outlet of its low pressure stage or the discharge output of its high pressure stage through opening a valve in a line connecting the discharge outlet of the low pressure or high pressure stage with the inlet of the low pressure stage.
