  • Static pressure testing apparatus
    Patent number: 5092162
    Abstract: A pressure testing apparatus for a fire hose utilizing a source of water under relatively low pressure and flowable at relatively high volumetric rate. The apparatus employs a manifold using a hose filling valve. The source of water communicates with the manifold and a low pressure inlet of a pump. The outlet of a pump pressurizes the manifold at a relatively high pressure. Check valves prevent back flow from the manifold to the source of water and the outlet of the pump. A regulator valve is positioned in the manifold to determine the highest pressure found in a portion of the manifold for filling and testing the fire hose.

  • Apparatus for determining interskeletal distances
    Patent number: 5082003
    Abstract: Apparatus for determining the distance between points on first and second skeletal bodies. The apparatus may continually achieve such distance determination during relative movement between the skeletal bodies. The apparatus includes first and second clamps or aimers each including a tip and base. Aimers are attached to the first and second skeletal bodies and are connected to an articulated linkage. The angular motion of the articulated linkages determines and correlates the movement between first and second aimers attached to the skeletal bodies. The signal produced by the articulated linkage is translated into a measurement of distance between the tips of the first and second skeletal bodies.

  • Apparatus and method for separating particles
    Patent number: 5080770
    Abstract: A method and apparatus for separating particles mixed with liquid utilizing a container for holding the same. The system also employs at least one separation membrane, which is permeable to the heterogeneous particles mixed with the liquid, divides the container into first and second separation chambers. A pump biases the flow of the particle liquid mixture from one side of the membrane to the other. Simultaneously, an electric field or potential is applied to the particle liquid mixture to bias flow of the same in the other direction.
