  • Patent number: 4776937
    Abstract: A method of producing ultrafine powders comprising metal silicide powder and the products produced by the method are disclosed. The ultrafine powders comprising metal silicide powders are ideally suited to form stable colloidal suspensions which are used in the production of conductive metal silicide containing films. The process employs gaseous reactants comprising a metal halide and a silicon-containing compound. The reactants are exposed to high intensity light to produce ultrafine powders. In addition to the production of metal silicide powders, the ultrafine powders may also include silicon powder and metal subhalide powder. The ultrafine powders are particularly suited for use in VLSI and VVLSI production.

  • Patent number: 4771605
    Abstract: A master cylinder assembly (10) and method for manufacturing the same includes a housing 12 for movably receiving a pair of pistons (32, 34) which cooperate with seals (28, 30) to communicate fluid pressure to respective brake circuits during braking. A reservoir 40 is formed by an integrally molded single unit which also extends into the housing bore (11) to define a liner (46) which substantially positions the seals (28, 30) within the bore (11). A sleeve (26) is also positioned in the bore 11 by the liner (46). When the master cylinder assembly (10) is manufactured the reservoir (40) and liner (46) are formed simultaneously.

  • Patent number: 4772443
    Abstract: A fluid filter is formed by manufacturing an air laid batt containing randomly disposed structural fibers and a thermoplastic binder fiber. The interstices between the fibers are fixed by applying a latex resin to the batt, thereby fixing the pore sizes of the filtering media before the filtering media is molded. The filtering media is then molded into shape by using a plunger to tuck the media into an open cavity mold. The mold may be heated and pressure may be applied to the batt to mold the batt.

  • Patent number: 4770471
    Abstract: A proportioning valve assembly (10) in a housing (12) is pressure responsive to control the flow of fluid to a wheel brake. A proportioning valve (20) is disposed within a chamber (26) having an inlet (33) and outlet (114), the inlet (33) receiving pressure from a pressure generator such as a master cylinder. A poppet (80) of the proportioning valve (20) is connected by a shaft (90) with a plunger (100) disposed within another chamber (30), the other chamber (30) being isolated from fluid pressure in the chamber (26) housing the proportioning valve. A fluid-containing chamber (13) contains an inertia sensing mass (40) which engages a valve mechanism (34) that controls fluid communication between the fluid-containing chamber (13) and other chamber (30). A friction element (120) of the wheel brake engages a braking torque responsive valve (140) which communicates fluid pressure to a chamber (30a).

  • Patent number: 4767699
    Abstract: A reagent complex is disclosed containing (1) a probe polynucleotide having a target binding region complementary to a target nucleotide sequence and (2) a signal strand polynucleotide bound by base pairing to a portion of the target binding region. The signal strand is displaced from the reagent complex by the target nucleotide sequence and separated from intact reagent complexes. A digestable ribonucleotide segment of the displaced signal strand, such as a 3' , terminal segment, is digested to ribonucleotide phosphates, which are phosphorylated to ATP. The ribonucleotide phosphates or ATP are detected.

  • Patent number: 4767646
    Abstract: Aqueous overfinish compositions, yarns treated therewith, and methods of producing wet abrasion resistant cordage from the yarn are all disclosed. One of the compositions includes an oxidized polyethylene emulsified with a non-nitrogen, nonionic emulsifier and neutralized with an alkali hydroxide, and a compound selected from the group consisting of a siloxane of the comonomers dimethyl and 3-[(2-aminoethyl)aminopropyl], and an amide melamine wax. An alternate finish composition comprises an oxidized polyethylene, neutralized with ammonium hydroxide and emulsified with a non-nitrogen, nonionic emulsifier. Yarn treated with this alternate finish has enhanced wet abrasion resistance. Yarns of this invention are ideally suited for heavy ropes and other industrial cordage applications where wet and dry abrasion resistance and strength are desirable.

  • Patent number: 4766064
    Abstract: A diagnostic reagent is disclosed containing a complex of a probe polynucleotide (P) bound via purine/pyrimidine hydrogen bonding to a labeled polynucleotide (L). The probe (P) contains a target binding region (TBR) capable of binding to a target nucleotide sequence (G) of a biological sample. A method is disclosed in which contact with a sample containing the target nucleotide sequence (G) causes binding, initially between G and a single-stranded portion (IBR) of the target binding region (TBR). Thereafter the labeled polynucleotide (L) is displaced from the complex by branch migration of (G) into the (P)/(L) binding region. A volume excluding polymeric agent such as poly(ethylene oxide) (PEO or PEG) or other polyethers enhances the rate of appearance of displaced labeled polynucleotide. Determination of displaced labeled polynucleotide (L) gives a value which is a function of the presence and concentration of target nucleotide sequence (G) in the sample.

  • Patent number: 4765042
    Abstract: An improved moving cavity yarn texturing device is described. One improved feature is a two stage energy tube which provides for more effective filling of the moving cavity by the yarn. The first stage has a cross section with a major axis and a minor axis. The second stage has a cross section with a major axis and a minor axis whose ratio is less than that of the first stage. A second feature is an improved chamber design which employs a channel having a "V" shaped cross section which eliminates snagging of the yarn by the cavity.
