  • Publication number: 20030104024
    Abstract: Nitrogen containing compounds are effective as subterranean termite feeding stimulants/aggregants and as masking agents for concealing the presence of other compounds which are repellents to termites, when they are used in low concentrations, less than or equal to about 1000 ppm (0.1%, by weight). The nitrogen containing compounds may be formulated alone, or optionally in a bait or in combination with other compounds effective for controlling or marking subterranean termites.

  • Patent number: 6326119
    Abstract: A method of forming a toner having controlled properties for use in a developer composition finding particular use in a hybrid scavengeless development scheme includes feeding at least one binder and at least one colorant into a mixing device at a feed ratio, upon exit of the mixture from the mixing device, monitoring one or more properties of the mixture with at least one monitoring device, wherein if the monitoring indicates that the one or more properties being monitored is out of specification, removing the monitored mixture from the method and adjusting the feed ratio by adjusting the feeding of the at least one binder or of the at least one colorant, thereby retaining in-specification mixture in the method. The in-specification toner is ground, optionally together with a portion of one or more external additives, classified, and mixed with one or more external additives to obtain the toner having controlled properties.

  • Patent number: 5899168
    Abstract: An improved artificial diet or growth medium for rearing the insect parasitoid Catolaccus grandis is disclosed. The growth medium is composed of amino acid, mineral, vitamin, lipid, and carbohydrate fractions which are present in amounts and proportions effective to support growth of Catolaccus grandis, and the amino acid fraction includes alanine, glutamic acid, histidine and proline at concentrations of about 3.0-5.0%, 8.4-9.4%, 10.0-15.1% and 11.7-12.8%, by weight, respectively. The growth medium is suitable for mass propagation of C. grandis from egg to adult for their subsequent release as biocontrol agents. Alternatively, the growth medium may be used to support growth of adult female wasps of C. grandis for use as breeding stock for continued mass propagation.

  • Patent number: 5333237
    Abstract: A computer-aided expert system comprising a hypermedia structured expert system and a hypermedia-structured multi-level electronic document archive linked thereto. The expert system includes a knowledge base, an inference engine that interacts with the knowledge base to generate advice. A hypermedia interface having knowledge base transfer means is provided on a display that includes selectable areas that provide access to active and passive documents in the document archive. The document archive includes active and passive electronic documents interlinked by means of the hypermedia interface and linked to the expert system by means of the hypermedia interface. Each active and passive electronic document includes active document transfer means that provide for transfer from the active document to another active document, a passive document, or a knowledge base linked thereto.

  • Patent number: 4185339
    Abstract: A flush tank is provided including a lower outlet opening and internal structure for guided movement of a free spherical buoyant valve ball into seated position in the outlet opening of the tank after the flush water has been drained therefrom. The tank includes a float controlled water inlet valve and float operated structure for at least partially unseating the valve ball from the water outlet in response to the level of water within the tank exceeding a predetermined maximum established by the float controlled water inlet valve, in the event of a malfunction of the water inlet valve to completely terminate the entrance of water into the tank as the level of water reaches the aforementioned predetermined maximum. Further, the lower outlet opening includes an upwardly facing annular concave spherical seat of the same radius of curvature as the valve ball and the seat is defined by a tapering peripheral lip portion of a resilient valve ball seat.
