The present invention relates to an apparatus and method for rapid flash-like volatilization of high and low vapor pressure components from liquid or solid emanators which is in contact with a point or localized heat source. Vaporization is promoted by a geometrically small electrically resistive heating element with variable activation for pulsed or cyclic heating of an emanating surface containing the volatile components. The apparatus is primarily directed towards the treatment of residential air for fragrancing, odor elimination, treatment of insects or pests, air sanitization, air and surface antibacterial or antimicrobial treatment, or other ambient air or surface modification by way of gas or vapor distribution.

A composition for a Coating System (paint) which forms an insulating material being designed to both reflect infrared radiation and have reduced thermal conductivity. The coating system may be either a single Thermal Coating or may be a Thermal Coating used in combination with a Thermal Primer. The Thermal Coating is formulated using conventional techniques and a resin used in paint manufacture, but utilizes primary pigments and extender mineral pigments which preferentially reflect in the infra red area of the solar spectrum. A method of characterizing particulate materials for their infra red reflectivity is described, which provides a means for preferential selection of particulate additives based on their relative visible light and infrared reflectivity. Additionally the incorporation of hollow micro-spheres is desired to reduce thermal conductivity. The Thermal Primer is designed to provide adhesion between the Thermal Coating and the substrate on which it is applied and uses conventional techniques to achieve those properties. However it has been found advantageous to incorporate hollow micro-spheres with low thermal conductivity, such as glass, ceramic or polymeric micro-spheres and/or an extender pigment with low thermal conductivity such as calcined clay to further reduce heat flow through the Coating System.

A firearm grip with a rest is provided, which at least has a grip body with a hollow portion, a shell encasing and combined with an outside of the grip body and exposing a bottom of the grip body, and a rest received in the grip body and capable of being projected from the bottom of the grip body to position and support the firearm grip against a setting surface. The grip body and the rest can be coupled to each other by an elastic member that allows the rest to be resiliently retracted back into the grip body. Alternatively, the rest can be pivotally coupled to the grip body and rotatably retracted into the grip body. The above firearm grip eliminates the shortcomings of the prior art.

A composition for promoting the formation of clots in blood comprises a binder and a zeolite disposed in the binder, the zeolite having an adjusted calcium content. A method of forming a blood-clotting composition comprises the steps of providing a zeolite, combining the zeolite with a binder, and adjusting a calcium content of the zeolite to have an amount of calcium such that upon application of the composition to a wound, a heat of hydration is reduced and thereby heat transferred to the wound is reduced. A method of clotting blood flowing from a wound comprises the steps of applying a zeolite to the wound and maintaining the zeolite in contact with the wound for a predetermined amount of time. The zeolite preferably has an adjusted calcium content and is capable of producing a controllable blood clotting effect on the wound.

A plastic discharge tube extends through a swaged cap bore through a metal swaged cap. A conical cap portion of the metal swaged cap is pressed into a retainer ring passage through a metal retainer ring. A swage surface in the retainer ring passage swages the conical portion of the metal swaged cap thereby fixing the position of the plastic discharge tube in the swaged cap bore and locking the swaged cap in the retainer ring passage. The plastic discharge tube is inserted into a steel injection tube fixed to a soil cutting knife. A ring bottom positioning surface contacts and injection tube upper end of the injection tube. A delivery hose is telescopically received on a plastic discharge tube retainer assembly and the steel injection tube. Hose clamps clamp the delivery hose to the retainer assembly and the injection tube.

The ring assembly is positionable between the top and bottom cooking surfaces when the top housing is in its closed position. The ring assembly comprises a top ring, a bottom ring, and an optional center cooking plate. The center cooking plate is movable between (i) a closed position in which a space defined by the ring assembly is divided into top and bottom cooking cavities and (ii) an open position.

A plurality of pulses each having relatively low energy are consecutively applied to a subject fuse to cause breakdown, wherein the total energy of pulses is set in light of a prescribed breakdown threshold, which is calculated in advance. The subject fuse has a pair of terminals and an interconnection portion that is narrowly constricted in the middle so as to realize fuse breakdown with ease. A pulse generator generates pulses, which are repeatedly applied to the subject fuse by way of a transistor; then, it stops generating pulses upon detection of fuse breakdown. Side wall spacers are formed on side walls of fuses, which are processed in a tapered shape so as to reduce thermal stress applied to coating insulating films. In addition, pulse energy is appropriately determined so as to cause electro-migration in the subject fuse, which is thus increased in resistance without causing instantaneous meltdown or evaporation.

An apparatus and method are disclosed in which ultrasonic vibration is used to assist the degassing of molten metals or metal alloys thereby reducing gas content in the molten metals or alloys. High-intensity ultrasonic vibration is applied to a radiator that creates cavitation bubbles, induces acoustic streaming in the melt, and breaks up purge gas (e.g., argon or nitrogen) which is intentionally introduced in a small amount into the melt in order to collect the cavitation bubbles and to make the cavitation bubbles survive in the melt. The molten metal or alloy in one version of the invention is an aluminum alloy. The ultrasonic vibrations create cavitation bubbles and break up the large purge gas bubbles into small bubbles and disperse the bubbles in the molten metal or alloy more uniformly, resulting in a fast and clean degassing.
