  • Patent number: 5058860
    Abstract: A pair of plates of a hard material (a socalled ceramic material or the like), intended to form the members for flow control of a faucet of the socalled screw type, and having an extended control field, wherein at least one of the sides which define the passage opening of at least one of the plates of the pair has substantially the shape of an arc of linear spiral (Archimedes' spiral), and the end portion having the smaller width of the passage opening defined by this arc of linear spiral is located near the plate periphery. The stated shape like an arc of linear spiral may be chosen for one side of the passage opening of one plate only, or even for one side of the passage openings of both plates, but in this latter case it is needed that the two spirals have a different slope. By means of this pair of plates it is possible to obtain control angles extending in the field from 1/2 turn and 3/4 of a turn, for example angles of 230.degree. or 270.degree..

  • Patent number: 5059644
    Abstract: Polyacetal compositions containing 0.05 to 5 weight percent of an oxo-piperazinyl-triazine hindered amine light stabilizer wherein the hindered N.sup.4 atom in the piperazinone ring of the stabilizer is alkylated with a metyl, ethyl, or propyl group, said compositions being relatively stable upon exposure to UV light. A polyacetal composition containing a specific oxo-piperazinyl-triazine hindered amine light stabilizer wherein the hindered N.sup.4 atom is not alkylated is shown to be relatively stable upon exposure to UV light. Both compositions possess stability during melt processing and do not significantly lose physical properties upon exposure to heat and light.

  • Patent number: 5059638
    Abstract: A glass or mineral fiber-filled polyester resin comprising a polyetherester or poly(etherimide ester) or a blend of one or both of a polyetherester or a poly(etherimide ester) with poly(butylene terephthalate) or poly(ethylene terephthalate). The composition must not have a matrix phase of poly(butylene terephthalate) or poly(ethylene terephthalate). The fiber has substantially no adhesion for the polyester base resin. The glass or mineral fibers effectively control the coefficient of linear thermal expansion of the polymer blend. The low adhesive fiber does not result in the reduction in toughness associated with conventional reinforcing adhesive fiber (which is coated with a coupling agent for the resin).
