An apparatus for charging a dosimeter which has a capacitor connected between first and second electrodes and a movable electrode in a chamber electrically connected to the first electrode. The movable electrode deflects varying amounts depending upon the charge present on said capacitor. The charger apparatus includes first and second charger electrodes couplable to the first and second dosimeter electrodes. To charge the dosimeter, it is urged downwardly into a charging socket on the charger apparatus. The second dosimeter electrode, which is the dosimeter housing, is electrically coupled to the second charger electrode through a conductive ring which is urged upwardly by a spring. As the dosimeter is urged into the socket, the ring moves downwardly, in contact with the second charger electrode. As the dosimeter is further urged downwardly, the first dosimeter electrode and first charger electrode contact one another, and an insulator post carrying the first and second charger electrodes is urged downwardly. Downward movement of the post effects the application of a charging potential between the first and second charger electrodes. After the charging potential has been applied, the dosimeter is moved further into the charging socket against the force of a relatively heavy biasing spring until the dosimeter reaches a mechanical stop in the charging socket.

Dosimeter charging apparatus

Different embodiments of multiple branch systems in which each branch includes multiple stations, a carrier reversing tube closed at one end, and a diverter having separate ports individually connected to (a) a branch tube which facilitates carrier transfer to and from the branch, (b) station tubes respectively associated with the different stations of the branch, and (c) the carrier reversing tube. The branch diverters selectively complete carrier-conveying paths between (a) the stations of their respective branches or their respective branch tubes and (b) their respective carrier reversing tube. Each branch has a single air supply connected to its carrier reversing tube to alternatively and selectively transfer carriers between stations of the branch via the station tubes, diverter and carrier reversing section, as well as transfer carriers to and from the branch via the branch tube. The multi-branch system, in one form, includes a further diverter and associated carrier reversing tube which selectively interconnects a pair of branch tubes respectively associated with a carrier sending and a carrier receiving branch. Inter-branch transfer is effected by utilizing the air supply of the sending branch in the pressure mode to push the carrier into the carrier reversing tube of the inter-branch transfer network via the sending branch tube and network diverter, and utilizing the air supply of the receiving branch in its vacuum mode to pull the carrier from the network carrier reversing tube to the receiving station via the network diverter and receiving branch tube.
