  • Patent number: 9490630
    Abstract: A method and system for the prevention of Destructive Electrostatic Discharge (DED) damage to outer garments caused by triboelectric charge discharging to the wearer's body through a distinct point of discharge at a conductor in contact with or close proximity to the wearer's skin. The method consists of interposing an insulating layer of high dielectric strength at the conductor such that the conductor is insulated from either the skin of the wearer or the outer garment and the circuit of triboelectric charge through the conductor is broken. The system includes a conductor and an insulating layer positioned between the outer garment and the skin of the wearer on either side of the conductor.

  • Patent number: 8298594
    Abstract: A dry powdered animal repellent that does not harm animals or plants. The repellant uses dried and powdered blood meal mixed with chili powder and/or cayenne pepper. The repellant is mixed together in a large moisture resistant container and then sprinkled around or into the soil around plants or into a tunnel opening formed by a rodent. In the first embodiment, designed to repel dogs and cats, the composition contains a 60%/40% (w/w) mixture of blood meal and chili powder (with 10% or less moisture content) with the chili powder being made from peppers with a heat rating of at least 85,000 Scoville units or greater. In the second embodiment, the concentration of blood meal to chili powder is increased to 80%/20% (w/w) respectively, to promote greater plant growth and for greater absorption into worms or grubs living in the soil.

  • Publication number: 20100234981
    Abstract: The disclosed time capsule safekeeping system comprises a controlling organisation maintaining a secure registry system of data records relating to a plurality of physical time capsules and a secure storage system for a plurality of physical time capsules. Each physical time capsule is proactively assigned by the controlling organisation a unique identifying code and an at least one identifying device that facilitates access to the data record within an interactive computer based database and additionally prima facie proves ownership of the time capsule. The time capsules are stored within uniquely numbered crypts at the storage facility. Family crypts allow for the storage of a plurality of time capsules comprising a family group. Such a storage system allows for the use of lower cost mass produced time capsule components. The controlling organisation is of a form that gives confidence to the general public in its long term stability and longevity.

  • Publication number: 20080295864
    Abstract: A scavenging cleaner utilizing in combination within a cleaner body, a high-pressure liquid cleaner and recycling system, designed for substantially domestic use and in particular for where water use restrictions apply and for the cleaning of hard surfaces of any orientation. The cleaner comprises a reservoir of liquid, a supply and recovery sub-system with a variable capacity vacuum pump arrangement coacting with a pressure pump such that as the pressure pump capacity is decreased or stopped the capacity of the vacuum pump arrangement automatically increases to maximize liquid scavenging. Total electric current draw is maintained substantially constant and below a preset maximum. A flexible connecting hose system connects the body to a handheld delivery/brush/recovery head that is worked over the surface to be cleaned. Liquid is delivered at high-pressure to the surface with substantially all the liquid being recovered, filtered and repeatedly reused.

  • Patent number: 5877008
    Abstract: An electromechanical device for driving the tip of a microinjection cannula, or needle, through the outer barrier of a blastocyst, cell, or cell nucleus for the injection of cells or other bioactive materials. Either a flexible frame or a ram moving within a base member is employed. Cannula motion is achieved by means of a piezoelectric stack and spring return system. The thrust motion over a predetermined microscopic distance is achieved without cannula setback prior to the thrust movement. Instead of specially prepared beveled and tipped needles, standard unimproved cannulas or needles can be used.

  • Patent number: 5825501
    Abstract: A structure and yarn sensor for fabric directly determines pick density in a fabric thereby allowing fabric length and velocity to be calculated from a count of the picks made by the sensor over known time intervals. The structure and yarn sensor is also capable of detecting full length woven defects and fabric. As a result, an inexpensive on-line pick (or course) density measurement can be performed which allows a loom or knitting machine to be adjusted by either manual or automatic means to maintain closer fiber density tolerances. Such a sensor apparatus dramatically reduces fabric production costs and significantly improves fabric consistency and quality for woven or knitted fabric.
