Title: High-range and resolution determinate mount and positioner
Inventor: BROWN DONALD G
IPC: F16M11/12
Filed: 1990-04-04
Abstract: Abstract of The Disclosure The invention relates to a device for accurately positioning an object, such as  a mirror 3 used to precisely aim a  laser.   The  invention uses kinematic  principles  to  hold the  object.   Here a  2-2-2  kinematic  bipod system is employed.  The invention uses three actuators 5 to position the object.  Each actuator acts as a bipod restricting the object in two of its six degrees of freedom.  Each actuator has three degrees of freedom it can transmit to the object.  The actuator can rotate on its single-axis flexure 7 so that the actuator can rotate on one axis relative to support 4.  Each actuator has a two-axis coincident flexure 8 on one end for allowing the object to be moved  in two  rotational  degrees  of  freedom and the roller sleeve 50 allows a third rotational degree of freedom.   Each actuator is positioned circumferencially about the central coordinate axis of the object to be moved, 120 degrees apart.  Each actuator is powered by a stepper motor 6  which  drives  the  differential  roller  screw  accurately,  providing translational movement to the system in the shortest length possible.

Title: Electronic gap sensor and method
Inventor: WILLIAMS ROBERT S
IPC: B22D11/06
Filed: 1990-11-06
Abstract: An apparatus and method for  regulating  the  gap between a casting nozzle and a casting wheel in which the gap between the casting nozzle and the casting wheel is monitored by means of at least one sensing element  protruding  from  the  face  of  the  casting nozzle.  The sensing element is preferably connected to a voltage source and the casting wheel grounded. When the sensing element contacts the casting wheel, an electric circuit is completed.  The completion of the circuit can be registered by an indicator,  and the  presence  or  absence  of  a  completed  circuit indicates the relative position of the casting nozzle to the casting wheel.  The relative positions of the casting  nozzle  and  casting  wheel  can  thereby  be selectively  adjusted  to   continually  maintain   a predetermined   distance   between   their   adjacent surfaces.
