  • PUMP
    Publication number: 20140286809
    Abstract: A pump includes a second housing member in which a suction-side groove and a discharge-side groove are formed at a predetermined interval in a circumferential direction of a bottom of a pump chamber so as to be recessed in the bottom of the pump chamber. Fitting portions that are fitted to bosses are formed on an outer surface of the second housing member. A protruding portion, which overlaps with the bosses in a thickness direction, is formed so as to protrude from a surface of the housing on which the fitting portions are formed. A relief valve is provided in the protruding portion, and the relief valve discharges fluid from the discharge-side groove when pressure in the discharge-side groove is equal to or higher than predetermined pressure.

  • Structural Component that Will Fragment into Particles of Selected Geometry and Reactivity
    Publication number: 20140286818
    Abstract: An embodiment in accordance with the present invention provides a method for creating and consolidating fragments and a useable structure formed from said consolidated fragments. The method includes swaging a metal powder into a first consolidated structure. The consolidated structure is ground to form particles and the particles are sifted to select those with a predetermined diameter. The particles having the predetermined diameter can then be swaged into a second consolidated structure. The resultant second consolidated structure is therefore configured to fragment controllably. The second consolidated structure can also be formed from reactive metal laminates such that the structure also has chemical energy.
