Publication number: 20040078434Abstract: An automated method, system and program product for automated document export control are disclosed. In accordance with the present invention, a user, by entering one or more user inputs into a data processing system, builds and submits an electronic document export request specifying a document for which export authorization is requested, an identity of an export control reviewer, and an indication of an export control policy under which export of the document is permitted. In response to submission of the electronic document export request, the data processing system automatically notifies the export control reviewer of the electronic document export request and permits the export control reviewer to electronically access, review and annotate the electronic document export request.Type: ApplicationFiled: October 17, 2002Publication date: April 22, 2004Applicant: Lockheed Martin CorporationInventors: Richard G. Parker, Graham Rutherford

Patent number: 5900796Abstract: An electric noise suppressor is provided for suppressing high-frequency electric noise which comprises a thermoplastic housing and two ferrite members disposed therein. The thermoplastic housing is formed from two hingedly connected case halves, which are substantially identical. A ferrite member is secured to each case half by a laminated compressible adhesive-foam element, which is comprised of a resilient foam core layer and opposing adhesive layers disposed thereabout. Due to the resiliency of the foam core layer, the ferrite members are pressed into tight engagement within the thermoplastic housing. The end walls of the thermoplastic housing are formed with circular apertures, which are each formed with a diameter which is slightly smaller than the diameter of the cable which is engaged by the electric noise suppressor. The dimensional differences between the cable and the apertures allows the end walls to grippingly engage the cable at a predetermined location.Type: GrantFiled: May 29, 1997Date of Patent: May 4, 1999Assignee: Fair-Rite Products CorporationInventor: Richard G.

Patent number: 5896079Abstract: Common mode ferrite bead is provided for suppressing EMI/RFI. The bead includes a ferrite body of substantially rectangular configuration with top and bottom surfaces, first and second end surfaces and first and second side surfaces. Six apertures pass entirely through the body from the first end surface to the second end surface. Grooves may be provided in bottom surface. Two conductors are provided through the body such that each of the conductors passes through each of three of the apertures through the body. The opposed ends of the conductors are bent to fit in the grooves in the bottom surface of the body. These ends of the respective conductors define contact which can be soldered to conductive pads on a circuit board.Type: GrantFiled: June 24, 1997Date of Patent: April 20, 1999Assignee: Fair-Rite Products CorporationInventor: Richard G. Parker

Patent number: 5095296Abstract: A split ferrite bead case is provided for a flat conductor cable. The case includes opposed elongated slots for a flat conductor cable to extend through so that the split ferrite bead can suppress electromagnetic interference carried by the flat conductor cable. The opposed elongated slots include cable holding means which are operative to prohibit lateral and angular shifting of the flat conductor cable in the split ferrite bead and prevent the case from sliding along the length of the flat conductor cable.Type: GrantFiled: December 31, 1990Date of Patent: March 10, 1992Assignee: Fair-Rite Products CorporationInventor: Richard G. Parker

Patent number: 4801627Abstract: Vinyl chloride (VC) resins, particularly poly(vinyl chloride) (PVC) and chlorinated poly(vinyl chloride) (CPVC) are reinforced with glass fibers which have been sized with a particular aminosilane coupling agent and a particularly characterized basic film former. At the processing temperature of VC resin, containing a stabilizer against degradation during thermoforming, for example in an extruder, or on a mixing mill used to blend the resin with sized glass fibers, a reaction occurs between an aminosilane coupling agent and the VC resin which reaction involves C.dbd.C bonds in the homopolymer, provided the polymer film former in the size is more basic than poly(vinyl acetate) ("PVA"). The film former catalyzes the thermal dehydrohalogenation of the VC homopolymer at the fiber-resin interface so as to generate allylic Cl moieties in chains of the homopolymer, which moieties react with the amine groups of the aminosilane.Type: GrantFiled: August 18, 1986Date of Patent: January 31, 1989Assignee: The B. F. Goodrich CompanyInventors: Douglas B. Rahrig, Angelo J. Magistro, Richard G. Parker

Patent number: 4459387Abstract: A process is disclosed for photochlorinating poly(vinyl chloride), ("PVC"), suspended in liquid chlorine ("Cl.sub.2 ") which swells the PVC and permits chlorination to occur in a gel phase. PVC starting material is in the form of solid free-flowing macrogranules which are slurried in from about 5 to about 50 times their weight of liquid Cl.sub.2 in a reaction zone maintained at a temperature in the range from about -50.degree. C. to about 50.degree. C., and a pressure sufficient to maintain the chlorine in its liquid state. Since liquid Cl.sub.2 itself swells the PVC to provide a gel phase in which photochlorination occurs, no conventional chlorinated hydrocarbon swelling agents, catalytic materials and the like are necessary. The process may be operated as a batch process, or a continuous process. Typical chlorine content of PVC is about 56.7 percent by weight (% by wt.), and the product of chlorination is chlorinated poly(vinyl chloride), ("CPVC"). When formed, this CPVC is dissolved in the liquid Cl.sub.Type: GrantFiled: September 16, 1982Date of Patent: July 10, 1984Assignee: The B. F. Goodrich CompanyInventor: Richard G. Parker

Patent number: 4377459Abstract: A process is disclosed for the preparation of chlorinated poly(vinyl chloride), (hereinafter "CPVC" for brevity), in the form of free-flowing macrogranules which are derived from solid free-flowing macrogranules of poly(vinyl chloride), (hereinafter "PVC" for brevity), by causing from about 0.6 to about 3.0 parts by weight (wt) of liquid chlorine which are absorbed perunit wt of solid PVC macrogranules to react with the PVC, without shedding reacted material from the macrogranules. The macrogranules of PVC containing absorbed liquid chlorine held therewithin, are maintained in a wetted but free-flowing, apparently dry reaction mass (due to which the process is referred to as "the relatively dry chlorination" or "the low liquid chlorine" process), in a reaction zone maintained at a temperature in the range from about -50.degree. C. to about 50.degree. C., and a pressure sufficient to maintain the chlorine in its liquid state.Type: GrantFiled: August 14, 1980Date of Patent: March 22, 1983Assignee: The B. F. Goodrich CompanyInventor: Richard G. Parker

Patent number: 4247664Abstract: Novel compounds formed by alkylating a polyvinyl aromatic resin with a substituted 1,2-dihydroquinoline (hereafter "TMDQ" for brevity), are found to be powerful stabilizers for organic materials subject to oxygen and heat degradation. As antioxidants these compounds are essentially non-bleeding and non-staining in rubber and polyolefins. Compositions comprising from about 0.1 to about 10.0 parts by weight of the novel compounds per 100 parts organic material, are found to be essentially stable for extended periods of time under normal conditions of use.A process for alkylating a polyvinyl aromatic resin with TMDQ necessarily utilizes at least a stoichiometric quantity, with respect to TMDQ, of an anhydrous Friedel-Crafts type acid-acting metal halide catalyst in a solvent for the resin. The reaction is carried out at an elevated temperature preferably at about the boiling point of the solvent.Type: GrantFiled: October 2, 1978Date of Patent: January 27, 1981Assignee: The B. F. Goodrich CompanyInventor: Richard G. Parker
