Abstract: Pierson-Stockey 8-63 PHOTOSENSITIVE GLASSES                    Abstract of the Disclosure This invention is concerned with the preparation of glass articles wherein a portion thereof is opaque and another portion thereof is transparent and, optionally, integrally colored.  The opaque portion is produced through the thermal reduction and precipitation of a controlled number of submicroscopic particles of at least one metal selected from the group of copper, gold, palladium, platinum, and silver with the subsequent nucleation and growth of NaF crystals on said metal particles to a size sufficient to scatter visible light.  The transparent portion is developed through the photoreduction of at least one photosensitive metal selected from the group of copper, gold, and silver to produce additional submicroscopic particles of said metals upon which NaF crystals are nucleated and grown, but which remain in a size too small to scatter visible light.  The presence of copper or gold alone gives rise to a single color, whereas the inclusion of  silver permits a full spectrum of colors to be produced.      Where silver is present, microcrystals of NaF contain-ing a silver halide selected from the group of AgCl, AgBr, and AgI are grown upon which a coating of metallic silver is developed or within which metallic silver is deposited.      The method involves sequences of exposures of the glass to high energy or actinic radiation followed by heat treat-ments.

Abstract: ABSTRACT OF THE DISCLOSURE          A cutting press has a resilient die pad aligned with an axially reciprocal die rule having a cutting surface defined by generally equally spaced piercing points and cutting edges between the piercing points.  Each cutting edge extends from a piercing point toward a next adjacent piercing point for substan-tially the entire distance between the two.  The cutting edges extending in a direction away from the die pad at an angle with a line through the tips of the piercing points of between about only one and fifteen degrees, thereby forming a generally check-marked shaped cutting surface valley between each of the piercing points, the valley having a depth of not more than three six-teenths of an inch.  The piercing points thereby have to penetrate into the pad for a distance equal only to the depth of the valley for the die rule to completely cut through the thickness of the material being cut.

Abstract: ABSTRACT OF THE DISCLOSURE The present invention relates to a method of pro-ducing multiple contact assemblies and the contacts for use therein, and more particularly to electrical contacts formed by slotting blanks from a strip of material and subsequently bending the blanks and attaching a terminal post.  In known multiple contact assemblies, the contacts are formed by slotting blanks from a band and individually bending the blanks around a line of symmetry parallel to the longitudinal axis to the contact.  A termial post is then attached to each contact, and the contacts are individually inserted in an insulating housing.  However, due to the large number of steps required for the produc-tion of the individual contact blades, the above process is time-consuming and expensive.  In addition, due to the shape of the blanks, there is a great deal of waste when the blanks are slotted from the strip of material.  According to the method of the present invention, a plurality of blanks are simultaneously bent around a common axis, while the blanks are connected together by a web.  The advantages of the present process are due to the fact that the connected contact members are bent simultaneously around common axes of bending, so that the terminal posts can be simul-taneously applied to the contact members and welded in a single step, whereby all the contacts can be simultaneously inserted into the insulating housing.

Abstract: (Weisse) E??:vk UNITED STATES PATENT AND TRADEMARK OFFICE      Title:    MULTICHAMBER PHOTOREACTOR      Inventor: G?nther O.  Schenck ABSTRACT OF THE DISCLOSURE Various embodiments of photoreactors are disclosed which have at least two irradiation chambers with a window therebetween.  Ultraviolet radiation is introduced into one of the chambers at a side opposite the window so that it passes through that chamber, through the window and into the other chamber.  The fluid medium to be purified is passed through the chambers and subjected to the radiation while in the chambers.  The flow of the medium is through the chambers in series in some embodiments and in parallel in others.  An embodiment is disclosed wherein a recirculation line is established around the reactor with the recirculation being continuous or intermittent.  When intermittent the purified fluid medium also is drawn off intermittently, between the periods of recirculation.  In some embodiments the amount of radiation transversing all the chambers is monitored.  If the monitored amount drops below a given amount, the apparatus is shut down.  Alternatively, the rate of flow of the medium is adjusted, based on that mon-itored amount, with the rate of flow increasing or decreas-ing, respectively, in response to increases or decreases in that amount.
