Patent number: 5692870Abstract: An apparatus is provided for inserting workpieces such as electrical components into a workpiece holder. The apparatus includes a housing with push pins mounted on a press plate for engaging and inserting the workpieces into receptacles in the workpiece holder. The pins are mounted in such a manner that if the entire housing is pushed downward in the direction of the exposed pin shafts and perpendicular to the plane of the bottom surface of the press plate, and if a given pin shaft encounters a restrictive force greater than or equal to a predetermined safe resistance, that pin shaft will be allowed to travel upward vertically through the plate frame. This escape release feature thus has the effect of a vertical "clutch," preventing damage to the pins, the loading plates, and the components whenever the pin shaft encounters excessive resistance.Type: GrantFiled: April 16, 1996Date of Patent: December 2, 1997Assignee: Electro Scientific Industries, Inc.Inventor: Douglas J.

Patent number: 5637968Abstract: A method and apparatus for correcting torque overshoot in power tools wherein torque per angle rate is sensed on each rundown and the speed of the tool is automatically adjusted to maintain torque accuracy on higher torque rate joints while maintaining speed on lower torque rate joints, automatically minimizing tool heating and maximizing job rate. In the setting of threaded fasteners, joint rates are defined as high (hard), medium or low (soft). Two torque points are defined, a first torque point and a second torque point, which are percentages of the target torque, for example 25% and 50% respectively. Two angle values are defined corresponding to the number of degrees of tool spindle rotation measured along the portion of the torque/angle curve between the first torque point and the second torque point on typical linear hard and medium joints.Type: GrantFiled: October 25, 1993Date of Patent: June 10, 1997Assignee: The Stanley WorksInventors: Stephen M.

Patent number: 5233742Abstract: Make-up of a pipe section and coupling to form a tubular joint having proper stand-off at proper make-up torque is automatically controlled. The coupling is first rotated onto the pipe section to a hand-tight position and the length of the coupling and the distance from the open end of the coupling to the pin end of the pipe section are measured by a digital measuring device which inputs these measurements to a computer. The number of turns of the coupler required to attain optimum stand-off is calculated by the computer. The pipe section is held stationary and power tongs rotate the coupling further onto the pipe section while the applied torque and the number of turns are measured and provided as inputs to the computer. The computer determines that the made up tubular joint is acceptable or not acceptable during the rotation by determining if the stand-off is within a predetermined make-up stand-off range at the same time that the make-up torque is within a predetermined make-up torque range.Type: GrantFiled: June 29, 1992Date of Patent: August 10, 1993Inventors: N.

Patent number: 4347546Abstract: Inspection apparatus is especially useful to verify the presence of metal parts such as pull tabs on can-production lines and to shut down lines not only if parts are missing or misplaced, but also if the sensors are shorted or the timer switch or circuit operation has otherwise been disturbed. Four stages of operation are coordinated with the mechanical progress of the machine, regardless of its speed of operation; these stages are the activating and deactivating of sensors (usually just before and just after a mechanical operation), then on switching a timing switch to low, and then on switching it back to high just before the sensors are again activated. At and after the stage of deactivation, the sensors are read for actual lack of signals, and latches of their signals during activation are also read to determine whether the parts were actually sensed. The signal to read is turned off when the timing switch goes high.Type: GrantFiled: August 25, 1980Date of Patent: August 31, 1982Inventor: Paul J. Unnerstall
