摘要： A machining center for machining a variety of different workpieces. Tool heads with a wide variety of tools are transferred from a storage area and oriented and presented one at a time by a turret to a machine tool in which they are received, accurately located, securely clamped and driven to machine a workpiece. A transfer device moves tool heads from a tool head circulating mechanism to the turret.

摘要： A linear actuator divert switch, a limited angle motor driven divert switch and a limited angle motor driven cross-over switch are provided for sortation conveyors. In addition conveying members of inverted substantially "U" shaped having spaced relatively hollow legs spanned by a bridge that is either hollow or not are also provided for sortation conveyors. A package diverter is formed with a cavity extending therethrough to surround the conveying member and so as to carry a divert/guide pin and cam follower part of which is disposed in the space between the conveying member legs to provide a relatively high positioning for divert/guide pin and cam follower with respect to the conveying members. Special lands extend out from the walls of the cavity to cock each package diverter on its conveying members in the direction of conveyor movement. The divert/guide pins are formed with a generally football shaped cross-sectional configuration to facilitate passage thereof through the various switches.

摘要： A conveyor and method for preventing stick-slip friction conditions from exciting the conveyor into surging and for preventing surging vibration from adversely affecting operation of the conveyor. The conveyor has a pair of endless, flexible roller chains that are laterally spaced apart and carried on sprockets keyed to a drive shaft that is in communication with a drive at one end of the frame and sprockets keyed to a take-up shaft at the opposite end of the frame. Preferably, the take-up shaft is split into two shaft sections rotatively secured adjacent their ends by a pair of bearings on a mounting block to permit each conveyor chain to move on its idle sprocket independently of the other chain. The conveyor components are selected to provide a combination of chain stiffness and conveyor mass moment of inertia at maximum payload that produces a conveyor having a high enough natural frequency to prevent stick-slip friction conditions from exciting the conveyor chains into surging. Should a conveyor possess a natural frequency falling within the range of natural frequencies causing the conveyor to be susceptible to surging, a dampener that includes a flywheel disc coupled to the conveyor take-up shaft by a spring is attached to one or preferably both ends of the take-up shaft of the conveyor for preventing stick-slip from exciting the conveyor chains into surging and reducing the amplitude of any surging vibrations which might occur so they do not adversely affect operation of the conveyor.
摘要翻译：用于防止粘滑摩擦条件刺激输送机进入浪涌并用于防止浪涌振动不利地影响输送机操作的输送机和方法。输送机具有一对无端的柔性滚子链，其横向间隔开并且承载在链轮上，链轮被连接到驱动轴上，驱动轴与框架的一端处的驱动器连通，并且链轮被链接到相对的卷取轴框架结束。优选地，卷绕轴被分成两个轴部分，两个轴部分通过安装块上的一对轴承旋转地固定在其端部上，以允许每个输送链条在其空转链轮上独立于另一个链条移动。选择输送机部件以提供链刚度和输送机质量惯性矩的组合，以产生具有足够高的固有频率的输送机，以防止粘滑摩擦条件刺激输送链进入浪涌。如果输送机具有落在固有频率范围内的固有频率，导致输送机易于浪涌，则包括通过弹簧联接到输送机卷取轴的飞轮盘的阻尼器附接到一个或优选两端输送机的卷取轴，用于防止粘滑剂刺激输送链进入浪涌并减小可能发生的任何浪涌振动的振幅，从而不会对输送机的操作产生不利影响。

摘要： A system for electronically storing revisions or modifications to documents which are already electronically stored in unrevised or unmodified form. The system compares, at the pixel-by-pixel level, a modified document bit map with a stored document bit map and determines from the differences between the two bit maps, at the pixel-by-pixel level, which differences are significant and which are insignificant. A revised document bit map is then formed from the portions of the stored-document bit map exhibiting no significant bit map differences and the significant differences bit map. The result is a revised document bit map in which no unnecessary changes have been introduced into the initial stored-document bit map. The system also includes steps for defining, on a pixel-by-pixel basis, a significant region bit map from the significant difference bit map and for forming the revised document bit map using the significant region bit map.

摘要： An auto-changer for optical discs. At least one carousel rotatable about a horizontal axis stores a large number of discs. A picker moves into the carousel to grasp a disc in a horizontal position in the carousel and then move the disc to a position outside of the carousel. A transfer arm grabs the disc from the picker and swings the disc in an arcuate path over to a disc player, where it is deposited for playing.

摘要： A velocity servo comprising a servo drive package (7) including a servo motor (8) and a feed back loop including a tachometer (9) coupled to the servo motor (8). An analog velocity command (6) and a command pulse train (21) are generated by a velocity profile generator (1) and the command pulse train (21) and a feedback pulse train from a pulse generator (10) are connected to a position error counter (11) which compares these pulse trains and generates a digital output representative of the difference therebetween. This digital output is transformed to an analog position error signal (22) having the correct polarity, and an operation amplifier (13) sums the velocity command and the position error signal to drive the servo drive package (7).

摘要： An integrated wire/surface guidance system (100) is disclosed wherein automatically guided vehicles (102) are made to follow a predetermined guidance layout (122). The guidance layout (122) comprises guidewire segments (130) forming wire loops buried beneath the floor surface (124). The guidance layout (122) also includes surface guidepath segments (144), and each of the vehicles (102) includes a surface guidepath sensor arrangement (190) and a buried wire sensor arrangement (172) for detecting the position of the vehicle (102) relative to the surface and buried wire path segments (144, 130), respectively. A control system (170) mounted on the vehicle (102) selectively controls acti vation of the sensor arrangements (190, 172) and is responsive to sensing signals received from the sensor arrangements so as to control steering and movement along either type of segment, in addition to selectively switching detection control between the same.

摘要： An in-process grinding gauge providing a means for continuously indicating the diameter of a cylindrical workpiece (13) being ground comprises a mounting bracket and gauging head arrangement including a body (14) carrying fixed upper and center pads (18,20 respectively) and an arm (22) pivotally secured to the body (14) and carrying a lower pad (21), and an arm spring (27) for urging the lower pad into engagement with the workpiece. A leaf spring (11) is secured to a mounting brakcet (12), and has a free end to which the gauging head (10) is secured. The gauging head is positioned so that the upper and center pads (18, 20) engage the workpiece (13) which is to be ground to size, the leaf spring (11) and the arm spring (27) comprising means for continuously maintaining all three pads in contact with the workpiece as it is ground to size.
