Abstract: APPARATUS AND METHODS FOR FORMING A PLURALITY OF                   ELONGATED MEMBERS            Abstract of the Disclosure A plurality of separate, elongated, metallic members, such as wires, are formed simultaneously, e.g., through the application of hydrostatic extrusion techniques, by passing a single metallic workpiece through a die with a plurality of apertures.  The apertures extend longitudinally through the die from an entry wall of the die, and are so arrayed, and the die entry wall includes surfaces which are so configured, as to cooperate to create cross-shear stresses in the material of the workpiece in the vicinity of the apertures.  These cross-shear stresses separate, or assist in separating, the workpiece into a plurality of elongated members, so that the forming process may take place at reduced operating pressures.           -i-

The waveguide is a circular symmetric  fiber having a cladding With an index of refraction n2 surrounding a core whose index of refraction is graded from an on axis value of n1 to a value of n2 at the core-cladding interface.  The index of refraction within the core is defined on terms of a profile function F by the following equation n2 = n?(1-F) where F is O on the axis and a function of the radial coordinate r and wavelength A within the core and satisfies the following equation   where D is a function of A having a value approximately equal to F for minimum modal dispersion and   is the group index on axis.     The modal dispersion achieved with this design is only a function of n1 - n2 and is independent of the profile dispersion

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention relates to electrical connecting devices and, particularly, to a novel insulation-piercing contact which may be used in a variety of electrical applications to effect solderless elec-trical terminal connections.  A number of disadvantages are associated with the prior art devices, resulting in their performance being not wholly satisfactory.  For example conventional prior art devices employ a thin, insulation-piercing jaw having a forked construction, with inside edges which penetrate the insulation and which also serve as contact surfaces to make the necessary electrical connection with the conductor.  While these thin inside edges facilitate the insulation. piercing function of the contacts, they do not serve as optimal elec-trical contacts because of the small surface area actually engaging the conductor.  Moreover, these edges have a tendency to cut or score the conductor thereby weakening the conductor and sometimes adversely affecting the desired current flow.  Accordingly, in the present invention, a novel insulation-piercing terminal element is employed with an active contact element. The insulation-piercing terminal includes insulation-cutting means to initially penetrate the insulation, insulation-stripping means to subsequently expose a longitudinal portion of the conductor and conductor-engaging means for establishing wiping engagement between the conductor and the contact member over an extended area.

Abstract: ABSTRACT OF THE DISCLOSURE A detector for x-radiation or other ionizing radiation comprises a pair of curved metal bars lying in spaced apart parallel planes. Ceramic members are bonded to the respective bars in facing relationship. Each ceramic member has a plurality of radially extending circumferentially spaced grooves facing similar grooves in the other member. A plurality of  electrode plates are held in juxtaposed and circumferentially spaced apart relationship by disposing their respective upper and lower edges in the grooves of opposed ceramic members. The faces of adjacent electrode plates define gas-filled gaps in which photoelectron-ion pairs are produced when radiation enters from the front edges of the plates.  The above described assembly is disposed within a pressurized gas-filled chamber having an x-ray transmissive window adjacent the front edges of the plates. A cover encloses the chamber . It has insulator feed-throughs for connecting the electrode plates with external electric circuits. Photoelectrons and/or ions, created by the ionizing radia-tion, are collected on the electrode plates and thereby generate an electrical signa1 which corresponds to the incident ionizing radiation.

Abstract: MULTILAMP PHOTOFLASH UNIT ABSTRACT OF THE DISCLOSURE A photoflash unit comprising two parallel columns of horizontally disposed lamps mounted in a planar array with flash indicators aligned behind each lamp   The lamps of one column are staggered with respect to the other, and the two columns are located on opposite sides of the  vertical centerline of the unit.  The lamps are connected to switching circuitry for sequentially flashing the lamps in response to firing pulses applied to a connector at one end of the unit.  The two columns of staggered lamps are positioned so that the lowest lamp is located on the side of the unit centerline opposite that on which the lens axis is located when the unit is connected to a camera, thereby farther removing the closest lamp from the lens axis to minimize the "red-eye" effect.  The switching circuitry is connected to provide an order of flashing that proceeds alternately between the two columns from the lowest to the highest lamp of the array, thereby providing a more readily interpretable flash indicator pattern.

Abstract: ABSTRACT OF THE DISCLOSURE          A radiation curable coating composition for various substrates contains an adduct of acrylic acid and an epoxy resin (which may be modified with an anhydride, such as maleic anhydride), and a reactive acrylate monomer vehicle.          The coating composition can be pigmented and can also contain additives commonly used in coatings, such as wetting agents and flow control agents.  The coating composition does not require the usual hydrocarbon vehicles that give rise to air pollution problems.  Surface gloss of a UV cured film obtained from a pigmented coating composition can be increased by using a photosensitizer combination of 2-chlorothioxanthone and a phenylketone, such as benzophenone.  Adhesion of a cured coating is improved by replacing the tertiary amine co-sensitizer, at least in part, with dimethylaminoethyl acrylate.
