摘要： Braces for bracing objects in structures against forces due to earthquakes are tested by subjecting components of the braces for attaching the braces to the object or structure to cyclic loading of approximately 15 cycles. The cyclic forces are applied to different samples of the components at differing angles, and a load rating is determined for each angle. Prior to cyclic testing, forces are applied monotonically to the components in both tension and compression, the flexible loading direction of the component is determined from the monotonic testing, and the deformation that the component can resist when a load is applied in cycles is estimated from the monotonic testing.

摘要： A probe for measuring the temperature and moisture of a gas has an aspirated flow passage with a configuration that causes the gas to have turbulent flow and, therefore, to mix. A dry bulb thermometer and a wet bulb thermometer positioned in the flow passage downstream of the configuration that causes mixing measures the temperature and moisture of the gas. A wick and a water reservoir for keeping the wet bulb thermometer wet are cleaned and refilled by a flow of water through the gas passage. The gas passage is heated to prevent condensation of any moisture in the gas.

摘要： A method for quantifying droplet fluxes of a water mist spray uses different measuring apparatuses and compares the measurements of the two apparatuses with one another. One of the measuring apparatuses is an iso-kinetic sampling probe in which the air velocity of the portion of the water spray mist entering the probe is made equal to the air velocity of the water mist spray around the probe by connecting a source of vacuum to the probe. The drops of the spray entering the probe are prevented from passing out of the probe. The air velocity of the spray entering the probe is measured by an anemometer, the drops of the entering spray are collected in a reservoir, and the depth of water in the reservoir is measured by a differential pressure transducer. The output of the pressure transducer is sent to a computer that calculates the water collection rate based on the sectional area of the probe opening and the water collection rate in the reservoir.

摘要： A device for measuring the flux received by a specimen in fire test apparatuses has a copper disk or plate of the same dimensions and the same type of surface coating as a typical material specimen, an embedded heating coil and thermocouple, and an insulated sample holder similar to that used for a specimen. The transient response of the embedded thermocouple is measured for several different levels of imposed incident radiation without electrical heating and for several different known levels of electrical heating without any imposed radiation. The principle of Electrical Substitution Radiometry (ESR) is applied, and the transient responses to incident radiation and electrical heating under identical thermal conditions are compared to determine the amount of incident radiation that is actually absorbed by the device while it is being irradiated. The situations are kept thermally identical, thereby insuring that all effects due to heat losses (e.g. convection, radiation and conduction) are exactly the same.
