摘要： A method and multiple station flexible boring machine for transferring and locating a pallet carrying a workpiece to be machined. The machine has at least two machining stations and a part loading and unloading station adjacent a transfer table carried by a base for carrying, generally locating and transferring a pallet and a workpiece to each station. The pallet has a curvic coupling locator ring with a plurality of circumferentially spaced and generally radially extending teeth for complementary mating engagement with a locator ring on an independent base of each station to accurately radially, axially and circumferentially locate the pallet on the station base. At the load station, the locator ring on the pallet is received in complementary mating engagement with the locator ring on the load base accurately locating the pallet with respect to the base and a workpiece is loaded, accurately located with respect to the load base and clamped to the pallet. The transfer table generally locates and transfers the pallet from the load station onto the base of a first machining station accurately locating the workpiece for machining. After at least one machining operation is performed at that station, the table transfers the pallet and workpiece onto the base of the next machining station. Upon completing all machining operations, the pallet and workpiece are returned to the part load station where the finished workpiece is released and removed and thereafter another workpiece to be machined is loaded, accurately located and clamped to the pallet.

摘要： A synchronized drive for a slide with a slip clutch which dissipates excess energy in an overload or crash situation to prevent damage to the mechanism. The slip clutch is coupled between a servo motor and a gear reducer to dissipate excessive force during a crash or an overload condition. A position feedback transducer is coupled to the gear reduced downstream of the clutch to maintain synchronization, even after a crash or overload condition, without requiring any re-homing sequence.

摘要： Diversion-type switches and cross-type switches are provided for inclusion in suspended rail conveyor arrangements to form a rail conveyor system. Each of said switches includes at least one shiftable rail section movable between a first position of cooperation with spaced rails of one conveyor pathway and a second position of cooperation with spaced rails of another conveyor pathway. Rail alignment and load transmitting elements, in the configuration of coacting fingers and seats, are disposed at the respective end of the shiftable rail section and fixed rail section and coact therewith so that load forces acting on the shiftable rail section act to align the shiftable rail section with the spaced rails of the respective conveyor pathways and so that load forces applied to the shiftable rail section are transmitted directly to the fixed rail section. Operating elements, including cams and cam followers are provided to move the shiftable rail section to separate the rail alignment and load transmitting elements to shift the shiftable rail section and to bring together the rail alignment and load transmitting elements.

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： A counterbalance actuator is disclosed for reducing the energy required in weight lifting operations. The counterbalance actuator includes a piston and a flexible bellows attached to the piston. A bellows extension is attached to the top of the bellows with a gas impervious seal. The bellows extension permits the counterbalance actuator to achieve an extended stroke while allowing the counterbalance actuator to be collapsed to a reduced size.

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.
