  • Patent number: 6829799
    Abstract: A seat cushion including a first and second pillar positioned specifically for receiving the ischial tuberosities of a user. The pillars relieve the pressure of the ischial tuberosity areas, but are easy and inexpensive to manufacture. In addition, the position of the pillars can be customized for a particular user. Hence, pressure reduction is accomplished only where it is needed. The invention can be used on flat cushions and on cushions with a molded shape.
    Type: Grant

  • Publication number: 20020155518
    Abstract: The invention relates to a method for identifying chemical or biochemical agents capable of suppressing asexual reproduction in fungi. The method comprises identifying compounds that form a differential zone of development in the area surrounding the test compound on fungal agar plate cultures as compared to normal growth in the surrounding region. Active anti-sporulation compounds are identified based upon the observed suppression of spore formation in the absence of fungal mycelium vegetative growth inhibition. The invention also provides agricultural fungicide and antimycotic compositions, and methods of applying such compositions to control fungal diseases and /or conditions.

  • Patent number: 4782053
    Abstract: Fungicidal compositions comprise at least one morpholine-type fungicide and at least one imidazole derivative of general formula (I): ##STR1## or a salt thereof; where R represents an optionally substituted phenyl group, R.sup.1 represents an optionally substituted alkyl, cycloalkyl, alkenyl, aryl or aralkyl group, R.sup.2 represents an optionally substituted alkyl, cycloalkyl, cycloalkylalkyl, alkenyl, alkynyl, aryl or aralkyl group, and X represents an oxygen or sulphur atom or a group --NR.sup.3 --, where R.sup.3 represents a hydrogen atom or an optionally substituted alkyl group or R.sup.2 and R.sup.3 together with the interjacent nitrogen atom represent a 5- or 6- member saturated or unsaturated heterocyclic ring optionally containing one or two further heteroatoms. The compositions are particularly useful in combating wheat leaf spot and powdery mildews.
