Patent FR-2106362-A1 (FR)
Title: Piston/lifter for control rods - with automatic catch locking mechanism, for use in a nuclear reactor
IPC: B66F3/30
Filed: 1971-09-06
Abstract: Hydraulic poiston lifter has three axially movable parts in the interior of the piston maintained in a rest state in a lower terminal position by pressure accumulators. The upper of these parts supports the catch mechanism of the piston, which can be disengaged by the central part when this is displaced towards its lower terminal position, while the lower of the three parts constitutes a working piston subjected to the pressure of the motive fluid of the piston lifter; the latter has a slide, in contact with the central part and with mechanisms for pushing the catch mechanism into the piston lifter during the upward movement of the lower part and has a piston surface of dimensions, relative to the pressure accumulators which maintain it in a state of rest in a lower terminal position, such that the lower part has already been raised by the motive fluid to a pressure of this fluid less than that required to raise the piston lifter.

Title: Centrifuge with multi-wall cylindrical channels - for water purifcn
IPC: B04B11/02
Filed: 1972-01-10
Abstract: Centrifuge is for use in the sepn. of liq. substances or volatile solids from liqs. or gases with different specific gravities. It has a cylindrical sepn. wall at the evacuation end of each cylindrical channel; this wall is 5-15 mm thick and its extension forms two series of radial evacuation channels which open into the central evacuation pipe. Feed scoops extend on a closed drum above the channel linings up to the closing wall. Each lining wall, except the outer one, carries helical projections; they are fixed in a posn. so that, on rotation, and by the relative movement of the neighbouring linings, the liq. is directed in the evacuation direction. The clean liq. is sepd. from the dirty liq. by the sepn. wall because the dirty liq. is deposited by centrifugal force on the outer lining walls. The clean liq. is conducted by the evacuation channels to the outlets pipe. For an equal yield the centrifuge is substantially cheaper than one of the conventional type.

Title: Reactor bottom entry control rod with emergency hydraulic drive - by hollow piston has rolling contact between piston and surrounding tube
Inventor: BERGLUND AKE
IPC: G21C7/12
Filed: 1975-10-24
Abstract: An insertion device for a bottom-entry control rod of a nuclear reactor comprises a mechanical spindle-nut drive and a hydraulic drive for rapid run-in of the control rod; in normal operation in the spindle rotates with its threaded portion in a non-rotating threaded nut, while in emergency rod insertion a hollow piston, which surrounds both the threaded spindle and also the nut and normally rests on the top of the nut, is hydraulically driven upwards to run the control rod into the reactor core; the hollow piston is permanently connected to the control rod by a coupling. A guide tube surrounds the spindle, the nut and the hollow piston and has a seal at its top end, through which the piston passes. The bottom end of the hollow piston has a non-return ratchet device, which is normally non-effective during mechanical operation but comes into action when hydraulic operation is used and prevents the piston from falling back again after it has been driven upwards to drive the control rod into the core. The seal between the upper end of the guide tube and the hollow piston is constituted as a labyrinth seal consisting of a number of annular grooves on the inner, cylindrical face of the guide tube; contactless movement between this cylindrical face and the outer face of the hollow piston is ensured by a number of guide rollers each mounted on a horizontal shaft and housed in a recess inside the cylindrical surface of the guide tube and bearing against the outer face of the hollow piston. Pref. these guide rollers are of a hard metal. The rolling contact of the guide rollers is used as a substitute for the more commonly used sealing rings and graphite sealing bearing. The new arrangement is much more reliable, less subject to wear and unlikely to adversely affect the operation of the control rod.
