Abstract: A flame retardant polyamide composition comprising a polyamide, a non-halogenated, phosphinate-based flame retardant, an impact modifier comprising an alkene/acrylate copolymer/terpolymer, a flame retardant synergist and an optional reinforcing agent. The flame retardant polyamide composition demonstrates a passing value for a glow wire end product test as measured by IEC 60695-2-11, a passing value for a glow wire ignition test as measured by IEC-60695-2-13:201; a passing value (V0 rating) for UL94 performance at 0.8 mm; and an elongation at break greater than 2.7%, as measured by to ISO Test No. 527:2012.

Abstract: The invention relates to relatively short peptides (termed O-Superfamily conotoxins herein), about 20-40 residues in length, which are naturally available in minute amounts in the venom of the cone snails or analogous to the naturally available peptides, and which preferably include two disulfide bonds.

Abstract: A post hole digging tool has a semi-cylindrical blade member, an elongate handle member, and a pair of hand grip members which can be quickly and easily assembled and disassembled. The blade has a top end wall and a short cylindrical reinforcing ring at its upper end and is semi-circular in transverse cross section. The bottom edge and longitudinal edges of the blade are sharpened to provide soil penetrating surfaces. A threaded collar extends upwardly from the center of the top wall. The handle member is removably connected at its lower end to the collar on the top wall of the blade and extends upwardly in axial alignment with the central axis of the blade and has a tee-shaped portion at its top end. Each hand grip member is removably connected to the lateral ends of the tee-shaped portion and may have an outer covering of resilient material to provide a comfortable gripping surface for the hands of the user and prevent blisters.

Abstract: Good salt rejection, flux characteristics and resistance to degradation are obtained with semi-permeable reverse osmosis membranes made by coating a microporous substrate with a copolymer of a hydroxy containing methacrylic ester and methacrylic acid, and cross-linking the copolymer subsequent to deposition on the substrate.

Abstract: Impure sugar solutions containing charged particulate impurities are treated with strongly basic emulsion anion exchange resin particles to form flocs of the charged particulate impurities and the resin particles. These flocs remove dissolved ionic impurities because of their ion exchange functionality, and also remove color-imparting impurities.

Abstract: Sulfur dioxide and sulfur trioxide may be removed from gases over a broad range of temperature and moisture conditions by utilizing a class of resinous adsorbents which retain their capacity at low moisture levels. Preferred embodiments are those resins which may be thermally regenerated to recover the sulfur.
