Title: Venting pipe system coupling for e.g. radioactive liq. - with screw plug removable by slotted tool in t piece attachment
Inventor: SCHNEIDER DIETER
IPC: F16L55/11
Filed: 1978-10-20
Abstract: A coupling for a pipe, for example the coolant cleaning system of a pressurised water reactor, can be disengaged to purge the end section from contaminated coolant. The pipe end has an outer thread for a union nut and an inner thread for a plug which is screwed in up to a shoulder. The plug has a cross pin by which a slotted tool can be used to unscrew it, after a T-piece has been attached to the pipe and by the union nut. This allos safe venting of radioactive liquids or gases used as coolant, from the space between the pipe end and nearest step valve.

Title: Multiple fluid expansion energy extraction appts. - has number of succeeding expanders, with by=passing of subsequent expansion to obtain max. torque
Inventor: GREENE CLARENCE KIRK
IPC: F01K7/00
Filed: 1978-10-30
Abstract: The latest energy in expansible fluids is converted to mechanical or electrical energy, by the utilization of a number of expanders wherein succeeding expanders derive energy from fluid emanating from a preceding expander from which energy was previously derived. Bypassing, as desired, of subsequent expansions is carried out so that maximum torque can be obtained when desired. The mechanical outputs of the expanders are connected by differential energy distributing means so as to accommodate for changes in the relative capacities of the two expanders by reason of changes in conditions in such manner that the relative changes of capacities are accommodated by relative changes in the speed of the mechanical output of the expanders.
