Patent FR-2290740-A1 (FR)
Title: Bottom entry control rod with emergency hydraulic drive - by hollow piston has rolling contact between piston and spindle
Inventor: BERGLUND AKE
IPC: G21C7/14
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 the spindle rotates with its threaded portion in a non-rotating thread 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 pistons from falling back again after it has been driven upwards to drive the control rod into the core. The upper end of the threaded spindle is journalled inside the hollow piston by a number of horizontally rotating, vertical-axis guide rollers, each mounted upon a cantilevered shaft projecting upwards from the top end of the threaded spindle, so that they bear on the inner, cylindrical surface of the piston. Thus, during normal operation, these rollers simply roll inside the hollow piston whereas, during emergency run-in of the control rod, they slide axiallu throughout virtually the full length of the hollow piston. Preferably, the length of each cantilevered shaft is at least twice the axial length of the rollers and the rollers are mounted in two or more different planes. The system of rollers on cantilevered shafts indicated is an effective substitute for the more commonly used sliding bearing of graphite, which is subject to high wear and is not very reliable inoperation.

Filed: 1977-07-13
Abstract: Dispositif permettant de compenser les fuites d'huile et les erreurs de synchronisme dans un ensemble de deux ou plus vérins dont l'action doit être synchronisée. Il comprend une butée sur laquelle les tiges de piston des vérins viennent buter en fin de course de retour, alors que, au même moment, s'ouvre une soupape assurant l'alimentation en huile sous pression des vérins, rétablissant ainsi les volumes d'huile normaux.

Title: Appts. for pyrolysis of hydrocarbon(s) - in which hydrocarbon supply is controlled to form hydrodynamic crater in molten heat carrier
Inventor: KHMELEVSKAYA ELENA DMITRIEVNA
IPC: C10G9/34
Filed: 1977-08-03
Abstract: Appts. for pyrolysis of hydrocarbons comprises a horizontally split casing contg. a molten heat carrier. Injector(s) for feeding a jet of hydrocarbons into the casing are mounted in an upper part of the casing so that the outlet of the injector nozzle is at, and directed towards, the surface of the heat carrier. Pyrolysis prods. are removed from an outlet in the upper part of the casing and heat is supplied directly to the heat carrier within the casing. The supply of hydrocarbons is controlled to provide a rate sufficient for the formation of a hydrodynamic crater in the heat carrier with a depth sufficient to ensure an intensive supply of heat to the prods. undergoing pyrolysis. Overheating of the casing material is avoided by supplying heat directly to the heat carrier.
