Abstract: A method and system for generating command signals for a computer monitor or other equipment. The system includes at least one pressure responsive potentiometer and a device operatively connected with such potentiometer for generating a command signal indicating at least one of the direction, intensity and duration of pressure applied to such potentiometer. The method remotely controls a function of a computer monitor or other equipment in response to signals obtained from pressure sensitive potentiometers manipulated by a user.

Abstract: An apparatus for heating powders or powder compacts for consolidation in a pressure vessel having a chamber. There is a device for directly induction heating the powder or powder compact. Additionally, the apparatus is comprised of a device for compacting a powder or powder compact. The device for directly induction heating the powder essentially provides uniform heating to the powder while the compacting device compacts the powder or powder compact in the chamber of the pressure vessel. A method for consolidation of powders or powder compacts which has the steps of heating directly by induction the powder or powder compact, and applying an isostatic stress to the powder or powder compact.

Abstract: The finishing apparatus is a grinder or like device having a workpiece holder manipulator which is translatable along X and Y axes and rotatable about a Z axis, an axis of tilt with respect to the plane of the X and Y axes and an axis normal to the plane of tilt. The grinder head is mounted on an arm which moves toward and away from the workpiece holder manipulator. All of the above movements are hydraulically powered through servo valves driven by feedback amplifiers, the feedback coming from position and rate transducers on the apparatus. Signals from those transducers are supplied through analog-to-digital converters to a digital computer with random access memory. The grinder is operated in the Teach mode by manually controlling the movement of the workpiece manipulator and grinder head to cause the grinding element to transverse the faces of a finished workpiece or a pattern thereof and the successive positions are stored in the memory.
