Abstract: The method and means for installing blind fasteners involves a pulling head design such that will cause the stem of the rivet pin to be broken at a predetermined location by a trimming or notching action of the head. This allows a previously unweakened blind fastener pin to be weakened for breaking at a prescribed location after the fastener is installed, thus accomplishing a pin break off substantially flush with the head of the fastener over an extremely wide range of thickness and types of materials being fastened. The pulling means may include a support housing which slidably receives a chuck assembly for pulling the blind rivet pin. A collet is also mounted in the support housing. The collet has suitable cutting edges for weakening the pin stem immediately adjacent the head of the rivet sleeve when appropriate load forces are reached. Cooperating cam surfaces on the support housing and collet react to the load forces to effect this weakening action.

Abstract: A calculator for continuously exhibiting the status of an individual's Bio-Rhythm cycles and, in particular, an individual's physical, emotional and intellectual Bio-Rhythm cycles. The calculator comprises a display panel having three dial faces corresponding to the three Bio-Rhythm cycles and each having indicia thereon defining the critical days within its particular cycle. Indicating elements are provided to sequentially scan each of the dial faces wherein the physical dial face is scanned once in a 23 day period, the emotional dial face once in a 28 day period and the intellectual dial face once in a 33 day period. A high or low critical day in any one of the Bio-Rhythm cycles is defined when the position of an indicating element corresponds to the critical indicia on a dial face. The calculator may be personalized by appropriately presetting the indicating elements relative to their dial faces based on data derivable from an individual's birth date.

Abstract: A method and apparatus for operating a pair of vertically disposed pinch rolls to facilitate the withdrawal of a strip of material from a rotatable mandrel is disclosed. The lower roll is operated conventionally at a preselected rotational velocity tending to advance the bottom surface of the strip through the rolls at a corresponding speed. The top roll is operated hydrostatically in response to strip speed and torque output feedback signals so as to maintain a constant output torque at a rotational velocity tending to advance the top surface of the strip at the monitored value of strip speed. As a result, the strip is advanced through the pinch rolls at a speed corresponding to the preselected rotational velocity of the bottom roll.

Abstract: The alarm system, which may be fastened to an object whose movement is to be monitored, includes a unique sensor array providing no output in any static orientation and a pulsating output in response to motional disturbances. A latch circuit is connected to the sensor array and develops a logically high output in response to a pulse from the sensor array. The output of the latch circuit remains logically high until the sensor array fails to output a pulse for a first predetermined time. A triggering circuit generates a trigger signal for activating a series of alarm functions after the latch circuit output has been continuously logically high for a number of the first predetermined time periods. Also, an alarm function may be connected to the latch circuit so as to activate whenever the latch output is logically high.
