Abstract: A thin metal wire 8 is fused and vaporized by a predetermined amount of electrical energy supplied to the thin metal wire 8 for a short period of time, whereby a blasting substance 3 is expanded in volume. Therefore, a vaporization expansion force caused by the fusion and vaporization of the thin metal wire 8 moves a shock delivering member 22, so that the shock delivering member 22, colliding with a to-be-blasted object H1, delivers a shock to the to-be-blasted object H1, thereby blasting the to-be-blasted object H1.

Abstract: A ventilation training analyzer manikin, for providing a quantitative measurement of the relative proportions of breathable gas volume delivered to a patient's lungs and patient's stomach during ventilation attempts by a user, thus demonstrating that the user is or is not using proper ventilation methods and equipment operating techniques. The manikin has a pressure actuated valve that opens at 15 cm H2O gas pressure to mimic the opening of the human esophageal sphincter. The opening of the valve at high pressure shows users that delivery of excess volumes of high pressure gas results in aspiration of the stomach contents, potential lung damage and risk of death in some cases.

Abstract: The invention relates to a lightweight gypsum coated decorative moulding, for installation on an interior building surface. The moulding is lightweight and flexible enough to withstand handling without cracking of the finished gypsum surface of the moulding. A gypsum coated surface is advantageous in that: fire resistance is enhanced; the moulding can be painted and repaired easily; and liquid gypsum compound can be used as an adhesive to install the lightweight moulding without mechanical fasteners or other support. Bevel joints can be cut with standard carpentry tools and the joints can be secured with liquid gypsum compound as well. The use of liquid gypsum compound as an adhesive and finishing coat ensures accurate fitting and finishing of joints as well as ease of repair. The moulding has an elongate foam core of a resilient expanded polystyrene foam solid, having a cross-sectional profile proportionately smaller than the desired cross-sectional profile of the finished decorative moulding.

Abstract: The invention provides a novel impact angle changing shower for spraying a fluid upon a moving belt surface while the belt travels at a selected belt velocity. The shower includes nozzles journaled to rotation about an axis in a plane normal to the belt surface and transverse to the belt direction. The nozzles are continuously supplied with pressurized fluid and direct a fluid stream at a selected nozzle velocity and nozzle angle relative to the plane. The orientation of the nozzles is selected to optimize the desired function namely, to clean the belt surface without damaging the belt fabric or felt, or to penetrate the belt to increase fluid absorption by the belt. The fluid stream nozzle velocity can be decomposed using vector mathematics into two vector components: a belt velocity vector component parallel to the belt direction; and a belt impact velocity vector oriented at an impact angle defined relative to the normal transverse plane.
