Abstract: A blood sampling instrument includes a blood collecting tube having a stopper fitted therein for maintaining the interior of the tube depressurized in order to collect a predetermined amount of a blood sample, and a holder into which the blood collecting tube is inserted in order to be used. When vulcanized rubber having a large permanent compression set or an inexpensive a polymeric composite material which does not require vulcanization is used as the material constituting the stopper, which will be punctured by a hollow needle, there is little frictional force produced between the needle and the stopper and, hence, the blood collecting tube may be forcibly urged away from the holder by the elastic restoration force of a collapsed rubber shroud in the holder when a blood sampling is taken. To prevent this from occurring, the blood collecting tube or the holder is provided with frictional resistance bodies so that the tube and the holder will engage each other frictionally.

Abstract: Lead with a low alpha particle emission is produced by selecting an orebody wherein lead mineral is present in a coarsely disseminated form and substantially free of impurities.  The ore is selected from a host rock that is relatively low in alpha emitters, such as a carbonate rock. The ore is mined and is mined such that the lead mineral can be separated from the host rock and any other minerals. The ground ore may be screened into one or more fractions having a narrow range of particle sizes.  Each fraction is formed into a fluid suspension, and each suspension is subjected to gravity separation to remove the host rock and any other minerals which substantially contain the alpha particle-emmitting substances, and to recover the lead mineral as a concentrate with a low alpha count.  The lead concentrate is subjected to a suitable reduction operation that may include a conversion of the concentrate into a reducible form, without the introduction of alpha emitters, for the recovery of a low alpha lead.  When the lead mineral is galena, suitable reductions include the smelting with sodium carbonate with or without an oxygen-bearing gas and electrolytic reduction in a molten bath of lead chloride. The low alpha lead recovered from these operations has an alpha count of about 0.02 alpha particle per cm2 per hour or less, and the count does not substantially increase with time.  The recovered low alpha lead may be further purified by electro-refining.

Abstract: ABSTRACT         A hydraulic actuator includes an actuator cylinder and a ram slidable therein from a retracted position to an extended position.   This rain has an axially extending chamber positioned in an end section and a number of outer passageways extend between this chamber and the outer surface of the ram. A locking ball is positioned in each passageway. A ring is slidably mounted on the ram and is positioned at its forwardmost point of travel to hold the balls so that they do not project from the passageways. A spring biases the ring towards its forwardmost position. A ball moving spool is slidably mounted in the chamber and has an annular ball receiving recess. A stop is located in an end section of the cylinder for preventing further forward movement of the ring and this stop causes the ring to slide rearwardly relative to the ram upon further extension of the latter.
