  • Publication number: 20080032924
    Abstract: The present invention provides antifungal and antibacterial peptides, especially antifungal peptides obtained from insect species, particularly lepidopterans. The present invention also provides methods of using these antifungal peptides to treat or prevent fungal growth for a variety of purposes such as; protecting plants from fungal infections, treating fungal infections of animals, especially humans, and prevention of food spoilage. In particular, the invention provides transgenic plants that produce an antifungal peptide, said plants having increased resistance to fungal infections/growth.

  • Publication number: 20060272908
    Abstract: A brake shoe key for attaching a railroad car brake shoe to a brake head has a stop which engages the brake head to limit the insertion of the key into the brake head's keyway. The stop is located on the key so that when it engages the brake head the knee of the key will engage the lug of the brake shoe and the tang of the key will be spaced from the brake head. This correctly positions the key for retaining the brake shoe while leaving space between the tang and brake head to permit access with a prying tool for subsequent safe removal of the key.

  • Patent number: 7030296
    Abstract: The invention relates to the identification and isolation of a polynucleotide molecule encoding a new class of protein insecticidal toxin produced by the bacteria Photorhabdus luminescens. The polynucleotide molecule may be incorporated into, for example, insect-specific viruses (including entomopox and nuclear polyhedrosis viruses), bacteria (including Gracilicutes, Firmicutes, Tenericutes and Mendosicutes), protozoa, yeast and plants for control of pest insects.

  • Patent number: 7029869
    Abstract: The invention relates to any assay for the identification of nematicidal compounds such as anthelmintics for the control of nematodes. The assay comprises: (i) incubating a nematode sample (i.e. a “test nematode sample”) containing a pre-determined amount of nematodes with an ingestable substrate labelled with a readily detectable label, under conditions suitable for nematode feeding, wherein said incubation is conducted in the presence of said candidate nematicidal compound or follows a pre-incubation of said nematode sample with said candidate nematicidal compound, and (ii) determining whether said candidate nematicidal compound affects nematode feeding by detecting an increase or decrease in ingested substrate as compared to that which has been ingested by a control nematode sample which has been incubated without said candidate nematicidal compound.

  • Publication number: 20040055036
    Abstract: The invention relates to the identification and isolation of polynucleotide molecules encoding a new class of protein insecticidal toxins which are produced by bacteria from the genera Xenorhabdus and Photorhabdus. The polynucleotide molecules may be incorporated into, for example, insect-specific viruses (including entomopox and nuclear polyhedrosis viruses), bacteria (including Gracilicutes, Firmicutes, Tenericutes and Mendosicutes), protozoa, yeast and plants for control of pest insects.

  • Patent number: 6177412
    Abstract: An insecticidal composition includes (1) at least one compound of formula (I): wherein R1 is bromine, chlorine, methyl, or ethyl, R2 is bromine, chlorine, or ethyl, R3 is hydrogen, halogen, or trifluoromethyl, X is —O—, —S—, or —NH—, and n is 2, 3, or 4, and (2) at least one compound of formula (II): wherein R and R1 independently are an alkyl, alkenyl, or alkynyl group containing up to 6 carbon atoms, R2 is hydrogen, an alkyl group containing 1 to 18 carbon atoms, a cycloalkyl group containing 3 to 8 carbon atoms, an alkenyl group containing 2 to 18 carbon atoms, or an alkynyl group containing 3 to 18 carbon atoms, R3 is hydrogen or an alkyl group containing 1 to 6 carbon atoms, and Y is —O— or —S—. A method for killing insects such as the tobacco budworm and other Lepidopteran pests of cotton includes applying an insecticidally effective amount of such a composition to an area to be treated.

  • Patent number: 4778548
    Abstract: A porous, woven carbon fabric friction material is bonded to a solid substrate, such as a conical transmission synchronizer, with a high temperature thermosetting adhesive, such as a synthetic rubber-phenolic resin base adhesive. Prior to applying the adhesive, a thin layer of one surface of the friction material is removed, such as by contacting the surface with a band-type sander, to break through the pyrolytic carbon coating on the substantial portion of the carbon fibers. The adhesive is applied to the abraded surface of the friction material and/or a roughened surface on the solid substrate, the friction material is clamped to the solid substrate and the thus-assembled parts are heated to at least substantially cure the adhesive. Improved bonds between the adhesive and friction material are produced and a tendency for the adhesive to "bleed through" the pores of the friction material and migrate to the friction surface during curing is significantly reduced.
