Abstract: Abstract of the Disclosure A socket for holding a baseless incandescent lamp to be in electrical contact with terminals of said incandescent lamp, includes a socket body having a receiving cavity with a  rectangular section into which a squeezed portion of said baseless incandescent lamp is to be fitted, a pair of terminal members attached to said socket body and to be brought in electrical contact with the terminals of said incandescent lamp when the squeezed portion of said incandescent lamp is fitted in said receiving cavity, and two pairs of ribs formed as a unit with said socket body and protruding from a facing pair of inner side faces of the receiving cavity of said socket body so that the projected ends of said ribs may elastically engage said squeezed portion in the vicinity of an exhaust tube of the lamp, the projected ends of two among said ribs squeezing themselves between said exhaust tube and the terminals of said incandescent lamp, thereby preventing   said terminals from moving toward said exhaust tube.

Abstract: ABSTRACT OF THE DISCLOSURE        An improved, hand actuatable pump assembly. A stem and piston assembly extend into a valve body. The piston sealingly engages the wall of the valve body and together they define a pressure chamber therebelow.  The piston seals a discharge passageway in the stem.  As the pump assembly is primed, air in the pressure chamber escapes through the discharge passageway.  When the pump is ready for use, the force of hydraulic pressure below the piston opens communication between the pressure chamber and pas-sageway.  When the piston nears the end of the stroke, it is mechanically held open to complete dispensing.  At all times, a positive seal between the piston and the valve body wall is maintained to prevent passage of the contents of the pressure chamber therebetween, thereby to minimize sticking and clogging of the pump assembly.

Abstract: ELECTRICALLY INSULATED CONDUCTORS WITH ULTRA-VIOLET CURED COATINGS Abstract of the Disclosure An electrical conductor for a telecommunications cable has a coating or layer of U-V cured material on the metallic conducting member.  The ultra-violet cured coating is partially cured before application of pulp insulation.  Further curing then produces a chemical bond between the ultra-violet cured coat and the pulp insulation to assist in holding the pulp on the conducting member.  The conductor is economic to produce while providing an efficient moisture barrier between the pulp insulation and conducting member.

Abstract: ABSTRACT        OXYGEN-CURABLE MERCAPTOORGANOSILOXANE COMPOSITIONS CONTAINING BOTH REDOX AND IRON CARBONYL COMPOUNDS AND METHOD OF FORMING HIGHER MOLECULAR WEIGHT PRODUCTS THEREFROM         Compositions, stable in the absence of oxygen, are formed by mixing the following substantially in the absence of oxygen: (A)  100 parts by weight of at least one mercapto-functional organosiloxane containing at least two mercapto-functional substituents per molecule; (B)  a catalytic amount of an iron carbonyl compound catalyst selected from the group consisting of Fe(CO)5, Fe2(CO)9, Fe3,(CO)12, dicyclopentadienyldiiron tetracarbonyl, butadieneiron, tricarbonyl and cyclohexadieneiron tricarbonyl, preferably from 0.1 to 6 parts by weight of catalyst per 100 parts by weight of part (A); (C)  optionally, at least one filler;      and (D)  0.1 to 6 parts by weight per 100 parts by weight of a redox compound such as copper (II) sulfate or iron (III) oxide. The compositions polymerize or sure to form higher molecular weight products upon exposure to oxygen.  The use of a redox compound appears to increase the cross-link density of the cured composition and results in harder resins and more durable elastomers.  An important novel feature of the redox compounds is that their use enables one to formulate compositions which cure to low-modulus elastomers possessing excellent unprimed adhesion to many common substrates such as glass, metal and concrete.  Such low-modulus elastomeric compositions are very desirable for use as building sealants.

Abstract: ABSTRACT OF THE DISCLOSURE            Disclosed is an apparatus for detecting magnetically conductive metals in a flow of material.  The apparatus includes a metal casing open at both ends thereof and adopted to receive the material flow therethrough.  Magnet bars are attached at two opposite inner walls of the casing in such a manner that, on one side, the north poles are directed inwards into the casing and the south poles are attached magnetically conductively to the casing, and on the other side the polarity of the magnetic bars is opposite, detector means being provided at the two remaining walls of the casing so as to detect the magnetic field at those positions.  Finally, electronic circuit elements are connected to the detectors in order to convert the detected magnetic field variations into an observable form.  The material flow may take place in a trough positioned within and extending through the casing.

Abstract: Abstract of the Disclosure Resin-forming polyepoxides are mixed with poly-oxazolidinyl compounds or polymers containing pendant oxazolidinyl groups in which the carbon atom in the 2-position of the heterocyclic ring is substituted with saturated hydrocarbon groups, such as dialkyl, or with an alkylene group forming a saturated ring with the carbon atom in the 2-position of the oxazolidinyl ring to form, in the absence of water, a stable composition which can be stored in closed containers for months without undergoing gelation.  When such compositions are spread into films and the films exposed to moisture at ambient temperature, e.g., to ambient air having a relative humidity of at least 20% and temperature of about 15° to 25°C., the polymer serves to react with and cure the polyepoxide.

Abstract: AN IMPROVED METHOD OF AND APPARATUS FOR MAKING IMPRINTED PAPER                           ABSTRACT      An improved method of making imprinted paper on a Yankee dryer type papermaking machine wherein a substantial length portion of a loop of imprinting fabric post-wraps an arcuate sector of the Yankee dryer immediately after a pressure roll-Yankee dryer nip, and by being tensioned imposes radially inwardly acting compressive loading on a corresponding length portion of the web disposed between the fabric and the dryer surface.  This enables, for instance, improved Yankee dryer speed, improved web tension and edge control of the paper when creped off the Yankee dryer, reduced use of adhesive on the Yankee dryer surface, im-proved fiber transfer efficiency, and reduced energy con-sumption per ton of paper made.

Abstract: OPTICAL FIBER SWITCH            Abstract of the Disclosure Switching between optical fibers is achieved through the use of a fixed and moveable housing disposed within a slotted support member.  The fixed and moveable housings respectively contain first and second sets of optical fibers.  Each housing has two grooved and parallel exterior surfaces.  Both housings are disposed in substantial abutment to one another in the slotted support member with the both sets of optical fibers parallel to one another.  The sidewalls of the slot are grooved to be the mating opposite of the grooved housing surfaces.  The first housing is fixedly positioned in the slot by the mutual engagement of the grooved exterior housing surfaces and the grooved sidewalls.  Switching between optical fibers is accomplished by the translation of the moveable housing surfaces to either of two positions which axially align a predetermined number of optical fibers in the first and second sets.  Each position of the moveable housing is precisely determined by the engagement of one grooved exterior housing surface and one grooved sidewall.

Abstract: Roadable Grouser for Track Shoes Abstract A roadable track shoe grouser is provided for track-type vehicles, for example, tracked farm tractors, to prevent damage to finished road surfaces when driving such tractors upon such road surfaces. The grouser includes a rubber grouser bar which is bonded to a mounting plate to facilitate replacement of the grouser after the rubber grouser bar is worn out by use.  Owing to interruptions in the bond provided to accommodate the heads of track shoe retaining bolts underlying the grouser, the bond is subject to premature failure, resulting in the loss of the rubber grouser bar from the track shoe.  The grouser described herein solves this problem by using a mounting plate having an aperture.  The aperture is of a size to receive a head of a track shoe retaining bolt.  A plug is of a size and construction to be press fitted into and close the aperture and to provide a continuous, uninterrupted bond interface across the mounting plate.
