Abstract: ABSTRACT         A high voltage switching system switches large load currents in short periods.  Gas is contained within an envelope at a pressure of the order of magnitude of at least 0.1 atmos-phere.  The gas provides a relatively high electron drift vel-ocity at a relatively low electric field strength.  A pair of electrodes are spaced apart within the envelope and are con-nected to respective switch terminals for connecting to a load.          The voltage gradient between the electrodes so spaced is insuf-ficient at rated voltage to produce any substantial secondary ionization.  The gas is ionized by a beam of high energy elec-trons introduced into the gas through the envelope.  Means is provided for turning the beam on and off, thereby closing and opening the current path through the gas and effecting the switching of current through the load.

Abstract: PREPARATION OF ACETYLENE-SUBSTITUTED         POLYIMIDE OLIGOMERS     Abstract of  the Disclosure An improved method is described for the preparation of certain acetylene-substituted polyimide oligomers which are substantially free of reaction solvent and thus do not fracture at use temperatures above 600°F. (316°C.).  The acetylene-substituted polyimide oligomers are prepared by reacting an aromatic tetracarboxylic acid dianhydride such as benzophenone tetracarboxylic acid dianhydride with an aromatic diamino compound such as a diamino polyarylene ether in the presence of N-methyl-2-pyrrolidone (NMP) as a solvent to form a first reaction product which is in turn reacted with an aminoaryl-acetylene to form a solution of an acetylene-substituted polyamic acid oligomer in NMP.  The polyamic acid oligomer is thereafter converted to the desired acetylene-terminated polyimide oligomer by heating in the continued presence of said N-methyl-2-pyrrolidone.          The N-methyl-2-pyrrolidone can then be removed by any suitable means such as by precipitation of the acetylene-substituted polyimide oligomer in a non-solvent such as ethanol.

Abstract: POSITIONING SYSTEM EMPLOYING FEEDFORWARD AND FEEDBACK CONTROL          Abstract of the Disclosure A positioning system for moving a member between positions in time optimal fashion employs concurrent feedforward and feedback control.  The feedforward control system provides coarse control and the feedback control system provides fine control to correct for deviations between the actual and a nominal system.  The feedback loop may thus be of low bandwidth permitting desensitization to high frequency disturbances or the employment of inherently low bandwidth controlled variables.    The feedforward control function includes successive portions of opposite polarity corresponding to acceleration and deceleration of the member and also includes a subtractive velocity related component.  This function represents the approximate input to an electromagnetic coil actuator of a nominal system required to move such a member between posi-tions in time optimal fashion.

Abstract: ABSTRACT OF THE DISCLOSURE          A reclinable chair is rockable on a frame which is movable forwardly on a base.  The chair and frame are supported on the base on a pair of facing channels which slope downwardly from the rear to the front of the base.  The frame and base are locked together in the rear and forward positions, the lock at the rear being released when the activating handle for the legrest at the side of the chair is raised 10 or 15°.  The further movement of the handle extends the legrest forwardly of the seat.          The seating of the occupant in the chair assists in the movement of the chair to the forward position during which a spring between the frame and base is tensioned for returning the chair to the rear position when the occupant leaves the seat and permits the springs of the seat to move upwardly and release the front latch.  A lever prevents the rocking of the chair until it reaches the forward position where it is stopped in its forward movement to release the chair for rocking.  When in forward position, the back of the chair may be reclined and the legrest may be extended in which position a ratchet mechanism becomes effective to prevent the chair from rocking or tilting forwardly.
