Abstract: ARMORED GRILLE                        ABSTRACT           A vehicle body armored grille (20) disclosed has particular utility with a front engine compartment opening (24) and includes vertically spaced louvers (26) of an improved armor plate construction for stopping projectiles from passing through the grille.  Each louver (26) has an elongated shape extending horizontally across the opening and includes an outer armor plate (30) that is inclined downwardly in an outward direc-tion and an inner armor plate (32) secured to and extending downwardly from the upper and inward extremity of the outer armor plate.  An upper extremity (34) of each inner armor plate (32) projects above the associated outer armor plate (30) to deflect a projec-tile impacted therewith upwardly toward the next higher louver.  Orienting the outer armor plate at an inclination of 45° with respect to the horizontal and the inner armor plate at a greater angle, i.e. 55°, defines an acute junction therebetween at which the plates are welded to each other and at which a pro-jectile deflected upwardly from the next lower louver is trapped.  Opposite ends of each louver (26) are welded to side plates (36) on a peripheral plate-like support (28), that mounts the grille on the associated vehicle body.

Abstract: ABSTRACT OF THE DISCLOSURE Novel shredded tobacco stem material having a much lower burn rate than other stem material and other beneficial properties and useful in the formation of cigarettes is formed by a novel procedure which produces only a rela-tively minor proportion of particulate material.  The pro-cedure, which is also applicable to tobacco stalk and tobacco winnowing, involves an initial thorough soaking of the stem, stalk or winnowings to a relatively high moisture level and mechanical fiberizing of the soaked material in a disc refiner at atmospheric pressure and preferably at ambient temperatures. The resulting shredded stem, stalk or winnowings in fibrous form is dried to the desired moisture level.

Abstract: ABSTRACT OF THE DISCLOSURE         Paper of improved properties is produced from pulp in which filler is selectively and substantially entirely loaded within the fiber lumens.  The paper is produced by vigorously agitating a suspension of pulp and an excess of insoluble filler having an average particle size smaller than the average pore size of the lumen entrances of the pulp fibers until the pulp becomes loaded with filler higher than the level desired in the paper and the lumens become loaded with filler to the level desired in the paper.  The filler-containing-pulp is separated from the suspension of residual filler.  The filled pulp is vigorously and turbulently washed (e.g., under conditions of shear, preferably with an aqueous solution of filler aid, e.g., alum) until substantially all of the filler on the external surfaces of the fibers is removed.  This procedure reduces the loss in strength values in the paper normally associated with filling paper and achieves high filler levels within the lumen.  The residual filler which is separated is recovered from the filler-containing pulp on fresh pulp.  Retention on the paper machine is increased by the use of such lumen-loaded fibers.  The papers have an enhanced combination of strength and optical properties.

Abstract: PRESSURE ACTUATED VENT ASSEMBLY      FOR SLANTED WELLBORES                   ABSTRACT OF THE INVENTION         A pressure actuated vent assembly for completing a slanted wellbore.  The assembly is connected in series relation-ship within a tubing string at a location below a packer, and the packer elements are located between the casing and the tub-ing string, thereby dividing the casing annulus into an upper and lower annular area.  The vent assembly includes a ported sliding sleeve which is slidably received about a ported main body member.  The sleeve is held into position by a shear pin.          Guide pins maintain the ports of the sleeve and main body member aligned with one another.  When pressure is applied to the in-side of the tubing, the sliding sleeve is forced  to slide from an upper closed position, in a downward direction, where the sleeve locks into the opened position.  The vent assembly is especially useful in slanted boreholes because various tools may be circulated down through the axial passageway of the assembly and downhole to perform a number of different downhole operations, such as completing a new wellbore, for example.

Abstract: PROGRAMMABLE CONTROLLER FOR USING              CODED I/O DATA TECHNIQUE               Abstract of the Disclosure A programmable controller has a scanner module that couples a main processor through two multidrop serial data channels to a relatively large number of remotely located I/O interface racks.  The main processor executes a control program to examine input status data coupled from I/O devices on a controlled system through the I/O interface racks and determines output status data which is coupled through the I/O interface racks to control output devices on the con-trolled system.  The scanner circuit encodes a stream of output status data by generating an output mask word and the adapter circuit encodes a stream of input status data by generating an input mask word, the mask words being appended to streams of status data that are coupled to and from each rack in serial data messages.  I/O status data that is selected for transmission over the serial data links is limited to data that has changed since the last time its associated I/O rack has been scanned, and refresh data that is periodically coupled to or from each rack, whether such status data has changed or not.

Abstract: TITLE               IODINE REMOVAL FROM A GAS PHASE          INVENTOR                    Andreas Ch. Vikis ABSTRACT OF THE DISCLOSURE Iodine, usually at least partially in the form of organic iodides, can be removed from a gas phase by irradiating the gas with radiation selected to photodecompose the iodides present until organic iodides have photodecomposed to elemental iodine, providing that ozone is present in the gas phase and reacting all iodine with ozone to form solid iodine oxides which separate from the gas phase.  If no organic iodides are present, the initial photodecomposition can be omitted, Where the gas phase contains oxygen the ozone can be generated photochemically in situ.  Alternatively, the ozone can be generated separately and fed to the gas phase reaction zone.  The method has application to removing radioactive iodine from air and other gases.

Abstract: MOLD ATMOSPHERE CONTROL SYSTEM            Abstract of the Disclosure A method and apparatus for maintaining a dehumi-dified atmosphere or other controlled atmosphere around the mold of a reciprocating-platen molding press, in which a sheet of light weight flexible material, preferably a transparent plastic film, is mounted on the platens, as by a plurality of permanent magnets, to form an open bottom tent enclosing both halves of the mold.  For a dehumidified atmosphere, a dehumidifier generates a stream of warm dry air that is continuously discharged into the tent, from locations adjacent each platen, with a volume sufficient to maintain the tent inflated for all platen positions despite continuing air loss through the open bottom of the tent.  The dehumidifier preferably uses a chilled water supply that is also employed to cool the molds in order to obtain automatic dew point correction. For other atmospheres, an appropriate source is substituted for the dehumidifier.

Abstract: ABSTRACT          High phosphorus polyphosphides, namely MPx, where M is an alkali metal (Li, Na, K, Rb, and Cs) or metals mimicking the bonding behavior of an alkali metal, and x = 7 to 15 or very much greater than 15 (new forms of phosphorus) are use-ful semiconductors in their crystalline, polycrystalline and amorphous forms  (boules and films).  MP15 appears to have the best properties and KP15 is the easier to synthesize.  P may include other pnictides as well as other trivalent atom-ic  species.   Resistance  lowering may be accomplished by doping with Ni, Fe, Cr, and other metals having occupied d or f outer electronic levels; or by incorporation of As and other  pnictides.   Top  contacts  forming  function  devices doped with Ni and employing Ni as a back contact comprise Cu, Al, Mg, Ni, Au, Ag, and Ti.  Photovoltaic, photoresis-tive, and photoluminescent devices are also disclosed.  All semiconductor applications appear feasible.     These  semiconductors belong to the class of polymer forming, trivalent atomic species forming homatomic, cova-lent bonds having a coordination number slightly less than 3.  The predominant local order appears to be all parallel pentagonal tubes in all forms, including amorphous, except for the monoclinic and twisted fiber allotropes of phosphor-us .     Large crystal  monoclinic  phosphorus  (a birefringent material)  in two habits, a twisted fiber phosphorus allo-trope and a star shaped fibrous high phosphorus material are also disclosed.     Single and multiple source vapor transport, condensed phase, melt quench, flash evaporation, chemical vapor depo-sition,  and molecular flow deposition may be employed in synthesizing these materials.  Vapor transport may be em-ployed to purify phosphorus.     The materials may be employed as protective coatings, optical coatings, fire retardants, fillers and reinforcing fillers for plastics and glasses,  antireflection coatings for  infrared  optics,  infrared  transmitting  windows,  and optical rotators.
