Abstract: ABSTRACT OF THE DISCLOSURE    A method and apparatus for producing stable and reproducible ultra-short lasing radiation pulses are disclosed. The duration of incoming pumping pulses for the dye laser arrangement is reduced in stages to produce the ultra-short pulses.  A first dye laser cavity of a series of at least two cascaded dye laser cavities is excited with lasing radiation pulses.  The lasing radiation pulses emerging from each dye laser cavity of the series are directed into the next successive dye laser cavity of the series.  The photon cavity lifetime of each dye laser cavity of the series is sufficient for a given duration of the incoming pumping pulses to produce the ultra-short pulses emerging from the final dye laser cavity of the series.  The maximum photon cavity lifetime of each dye laser cavity of the series is selected to thereby reduce in stages the duration of the incoming pumping pulses.  This reduction yields from the final dye laser cavity of the series the ultra-short lasing radiation pulses.

Abstract: ABSTRACT OF THE DISCLOSURE         An improved anode for use in the electrolysis of hydrogen chloride for the generation of chlorine gas in an electrolytic cell having a solid polymer electro-lyte membrane with a cathode bonded to one side of the membrane and an anode bonded to the other side of the membrane, is described.  The length of the diffusion path within the anode where the electrolytic oxidation takes place, is decreased or the porosity of the anode where the electrolytic oxidation takes place, is increased, to increase the rate of transport of the reactants (hydrogen chloride) and the reaction products (chlorine gas) within the anode.  The diffusion path length is decreased by de-creasing the thickness of the anode catalyst material.  A preferred anode catalyst for the oxidation of an aqueous hydrogen chloride solution has a thickness of about 6.0 microns to about 50.0 microns.

Abstract: ABSTRACT OF THE DISCLOSURE         Character matrices are stored in and retrieved from a magazine automatically.  The matrices can be complete discs or pie-shaped "petals" which are assembled to form a disc.  A single pivotably-mounted support arm is used to support the spinning disc, and to move it for selection of concentric arrays on the disc, as well as for storage and retrieval of matrices. A reversed zoom lens is used to magnify the characters.         The character spacing carriage can move continuously , in order to increase the speed of operation.  Proper location of the characters can be done by simply altering the carriage speed between projections, or by using a shuttling lens for character spacing compensation, together with flash delay and carriage deceleration.          A system for inputting images from any one of three separate discs also is provided.          A double-dove prism and optical wedges are used for altering the shapes of characters.          Rules are formed by operating a flash-lamp very rapidly to shine light through an appropriately-shaped opening and moving the image along the photosensitive surface in a linear path.          The matrix can be moved in a varying speed mode in which the matrix is moving slowly or stationary when the character is flashed.  This allows the light intensity of the flash lamp to be raised significantly without significant degradation of the quality of the output.          Controls are provided for automatically adjusting the base-line of the characters, the margins, the degree of enlarge-ment, the flash intensity, and the focus.          A simple attachment is provided for doubling or halving the size of the characters.

Abstract: COMPARATOR                            Abstract A comparator circuit cell has an output which switches between first and second states when an input voltage (or current) reaches a controlled trip point having a controllable positive, zero or negative temperature coefficient.  First and second common emitter transistors are forced to operate at different emitter current densities at the trip point thus requiring the operation of a .DELTA.VBE across a first resistor coupled between the bases of the first and second transistors in order to get the circuit output to switch.  The positive temperature coefficient current which flows through the first resistor to generate .DELTA.VBE is summed at the base of the second transistor with a negative temperature coefficient current flowing through a second resistor.  This creates a required input current having a controllable magnitude and temperature coefficient.  The input current may be provided through an additional resistor to the base of the second transistor to create a voltage input trip point having a controllable magnitude and temperature coefficient.

Abstract: CORONA CHARGING APPARATUS                      ABSTRACT OF THE DISCLOSURE         A corona charging device includes a dielectric-coated elongate conductor contacting or closely spaced from a control electrode.  In the first version of this device, the control electrode comprises a conductive grid, which is mounted against an insulating support and in a second version, the control electrode consists of a slotted conductor, with the dielectric-coated elongate conductor embedded in a slot.  A high voltage varying potential between the elongate conductor and control electrode induces a glow discharge in an air region in proximity to the two conductors.  The control electrode may act as a grounding member to provide a corona discharge device with respect to a proximate surface or alternatively, the control electrode may be maintained at a desired potential to provide a charging device with an automatically limited voltage.  The corona charging devices of the invention are characterized by a linear relationship between output ion currents and a direct current extraction potential.  In further versions of the second corona device, the slotted conductor and dielectric-coated conductor may be replaced with alternative structures which provide an equivalent enclosure.

Abstract: Abstract Described herein is an integrated process for the preparation of substantially linear high molecular weight thermoplastic polymers derived from aryl polyhalide monomers.  Aryl polyhalide monomers are first prepared by the reaction of an alkali metal salt of a phenol compound, e.g., dipotassium salt of bisphenol A, with a dihalobenzenoid compound, e.g., 4,4'-dichlorophenylsulfone, in a liquid phase of an aprotic solvent and an azeotrope former, e.g., toluene.  Water is removed from the reaction mass as an azeotrope until substantially anhydrous conditions are attained.  The aryl polyhalide monomers are then coupled by contacting the monomers with a catalyst mixture of a nickel compound and a ligand in the presence of a reducing metal, e.g., zinc, and an aprotic solvent under substantially anhydrous conditions to form substantially linear high molecular weight thermoplastic polymers.

Abstract: ABSTRACT OF THE DISCLOSURE      An efficient, portable, easy to operate fastener applying tool is disclosed that is powered by the gases produced from the internal combustion of a fuel and air mixture.  A supply of liquified gas stored under pressure in a cylinder provides the source of power.  A piston connected to a fastener driver is slidably mounted within a cylinder to move reciprocally downwardly and upwardly through a driving and a return stroke.  A combustion chamber is formed at the upper end of the cylinder.  A spark plug powered by a piezo-electric firing device, is located within the combustion chamber.  The combustion chamber features a set of fan blades driven by an electric motor which is continuously in operation when the tool is in use. main valve mechanism actuated by a set of lifting rods which are moved upwardly and downwardly when the tool is moved toward and away from the workpiece, is used to control the flow of fresh air through the combustion chamber.  When the combustion chamber is isolated from the atmosphere and the fuel and air are thoroughly mixed, the spark plug is fired to explode the fuel and air mixture and force the piston through its driving stroke.  A bumper is located at the lower end of the cylinder to keep the piston from striking the bottom of the cylinder.  Combustion gases are discharged from the cylinder at the end of the driving stroke which aids in producing a thermal vacuum within the combustion chamber.  Air supplied to the lower face of the piston from the atmosphere forces the piston through its return stroke.  A unique trigger interlock mechanism is provided to insure that the tool cannot be operated until the combustion chamber is closed and the combustion chamber cannot be reopened after ignition until the trigger is released.
