Title: Seal for rotating shaft exposed to sulphur - for electricity generation by binary cycle sulphur vapour and steam
Inventor: LAURENT ROBERT
IPC: F01K25/08
Filed: 1974-06-18
Abstract: The shaft has a sleeve which encloses molten sulphur which is maintained at a temperature between 170 deg.C and 200 deg.C. When the sulphur is in a viscous state. The sulphur in contact with the shaft remains in the liquid state due to friction, which results in a slight leak. To replace this leakage additional liquid sulphur is supplied which is cooled by water under pressure at a temperature of 180 deg.C. Since water vapour is inert with respect to sulphur there is no danger of the sulphur igniting at these temperatures as would be the case if the sulphur were in contact with air.

Title: Elimination of tubular hot-spots in heat exchange reactors - by dividing outer casing into individually temp.-controlled compartments
IPC: F28F9/26
Filed: 1975-01-03
Abstract: A tubular heat exchange reactor comprises a hollow casing divided into a series of compartments each with its own inlet and outlet and between each compartment there is a hollow tube box. Tubes, set into tube plates which form the walls of the tube box between compartments, traverse longitudinally each compartment linking all the tube boxes formed by the outer casing. Water boxes at each end of the outer casing form the inlet and outlet for the tubes, which can be packed with catalyst, if required. One or more thermocouples in each compartment of the outer casing sense the tube temp. and regulate via a temp. controller the flow of cooling fluid to the compartment, (heating fluid if the reaction in the tubes is endothermic). Used for tubular heat exchange reactor as used in e.g. catalytic oxidn. of benzene into maleic anhydride. Allows control of hot spots on the tubes which vary with condition of catalyst and/or varying concentrations of reactants or operating conditions. Increases output by permitting max. possible space-time output.

Title: Flow control device for air compressor - has purge orifice valve controlled by membrane
IPC: F16T1/12
Filed: 1975-04-18
Abstract: The air is cooled during its passage through a spiral tube (28) then enters the control device (14) through an opening (32). Oil and water are separated in a cyclone (34). At the bottom of the cyclone chamber is a purge valve (46) controlled by the pressure difference across a membrane (40) attached to a shaft (42). Air leaving the cyclone passes through a filter (50) to a non-return valve (54), a by-pass valve (53), a pressure reducing nozzle (52) and an auxiliary valve (55), these four being in parallel. These components work in conjunction with a humidity sensitive device placed downstream of the main filter (18) to operate the purge valve and to permit a reverse flow of air through the filter when the compressor is stopped, drying the filter, if this is necessary.

Title: High sensitivity differential relay - acts on the vectorial sum of network currents and has pinion magnification
IPC: H01H71/32
Filed: 1976-01-09
Abstract: The high sensitivity differential relay acts on a given threshold level of current which is the vectorial sum of circulating currents in the associated distribution network. The relay is intended to provide protection against overloads of about 30mA to 50mA, i.e. that level likely to cause electrocution. The threshold detector is two winding soft iron cored relay which operates through a series of pinions providing amplification of the initial relay armature movement to the contactor actually breaking the supply circuit. The speed of response and sensitivity to overload duration is governed by the pinion inertia. Overall geometry is minimised by having only two pinion planes.
