Abstract: ABSTRACT           A circular bore transversely excited gas discharge laser (10) is disclosed which may be con-structed and operated with no physical contact between the active discharge and the metal excitation electrode structure (14).  The discharge is excited by RF in the frequency range 10 MHz to 1 OHz applied to a transverse metal electrode structure (14) designed to maintain a relatively uniform electric field in the discharge bore (12). The disclosed laser may be configured as a wave-guide laser or a large bore laser operating in a non-waveguide mode.           A means for inductively coupling RF energy from a suitable RF energy source to the electrode struc-ture (14) and a means for attaching mirrors (15) to the discharge tube using no organic sealing material is disclosed.  Without physical contact between the active discharge and the metal excitation electrode structure or organic sealants, long lifetime, superior laser per-formance, and capability for liquid cooling of the discharge tube is achieved.

Abstract: ABSTRACT         A spacer formed of a relatively rigid frame is slidably adjustably mounted on and extends between a pair of horizontally spaced vertically extending ribs of electrostatic precipitator plates to maintain the plates in a predetermined horizontal spaced relationship. The frame preferably is formed by one or two rectangular-shaped frame members having U-shaped hooks attached thereto. The hooks are either attached directly to the plate ribs to frictionally slidably mount the frame between the spaced plates, or connect the two plates together with the plate ribs being clamped therebetween.  The frame members and U-shaped hooks preferably are formed of round metal bars.  The frame members are mounted on the ribs either at the top or bottom of the precipitator plates and then slidably moved along the ribs until posi-tioned at the desired vertical location.  The sliding clamping pressure of the frame members or hooks against the ribs enable the frame to be positioned between the plates without dismantling the plate supports and without a workman entering between the plates to attach the frame in the desired position.

Abstract: Abstract of the Disclosure A method and apparatus wherein there is provided a source of fiber forming material, with said fiber forming material being pumped into a die having a plurality of spinnerets about its periphery.   The die  is  rotated  at a predetermined adjustable speed, whereby the liquid is expelled from the die so as to form fibers.   It  is  preferred  that  the  fiber  forming material be cooled  as  it  is  leaving  the  holes  in the  spinnnerets during drawdown.  The fibers may be used to produce fabrics, fibrous tow and yarn through appropriate take-up systems.  The pumping system provides a pumping action whereby a volumetric quantity of liquid is forced into the rotational system independent of viscosity or the back pressure generated by the spinnerets and the manifold system of the spinning head, thus creating positive displacement feeding.   Positive displacement feeding may be accomplished by the  extruder  alone  or  with  an  additional  pump  of  the  type generally employed for this purpose.  A rot?ry union is provided for positive sealing purposes during the pressure feeding of the fiber forming material into the rotating die.

Abstract: ABSTRACT OF THE DISCLOSURE    An electron gun system  providing beam convergence is disclosed for use in a color CRT display system.  Means including cathode means develop three electron beams, two of which are off-axis with respect to a center axis of the gun. A plurality of electrodes means provide shaping and focusing, and assisting in the converging  of the beams at the tube screen.  Means are provided for developing and applying to the electrode means a pattern of potentials which form field components in the gaps therebetween; at least one of the electrode means receives  a varying dynamic focusing voltage for dynamically focusing the beams as they are deflected across the screen. At least selected ones of the plurality of electrodes means for the off-axis beams are so structured and arranged as to cause a plurality of the field components to be asymmetric and effective to converge the off-axis beams.  The strengths of the asymmetric field components vary in response to changes in the dynamic focus voltage.  The asymmetric field components according to the invention have such polarity and strength, due to the structuring and arranging of the electrodes, and the application of the pattern of voltages, that a change in the levels of the dynamic focus voltage causes a change in the strength of each of the asymmetric field in a direction effective to additively deflect a common off-axis beam in a common angular direction so as to create a strong dependency of the convergence of the off-axis beams on variations in the focus voltage.
