Title: Gas venting valve for switchgear - has hinged flap with pivoted laminations to allow outflow resistance to increase with pressure
IPC: H02B13/025
Filed: 1974-12-04
Abstract: The gas venting valve for switch gear in transformer substations etc. has a hinged main flap with fixed angled baffles and pivoted laminations. In normal conditions the gas in the switchgear escapes through the gaps between the baffles and laminations. When the pressure rises, due to short circuit or arcing, the laminations pivot to close the outlet gaps and allow the pressure inside the switchgear to rise. As the pressure increases further the large main flap is pushed outwards to allow the gas to escape through a port etc. The valve allows the outflow resistance to increase with pressure.

Title: Electrode plates of electrolytic cell arranged horizontally - are separated by sheets folded in u-fashion around each intermediary plate
Inventor: GOUALARD JACQUES
IPC: H01M8/24
Filed: 1974-12-11
Abstract: An electrolytic cell with electrode plates of alternate polarity arranged horizontally in a pile and having >2 end plates and 2 intermediary plates, has a porous separator impregnated with electrolyte formed from several sheets separating the electrode plates. Each intermediary plate has a separator sheet folded in U-shape about it so that 2 adjacent plates are separated lby 2 separator sheets. The separator sheets have at leasts the same contact area as the electrode plates and can be made to overlap the separator sheet of the plate adjacent to it so that it is in contact with the adjacent electrode plate and not the one to which it is attached. >=1 of the end plates of the pile has a separator sheet folded round it so that one part of the sheet is external to the pile of electrodes and the other part is between the end plate and the adjacent plate. In electrolytic cells and in particular electrochemical generators, e.g. nickel-hydrogen accumulator. In existing cells during working the electrolyte tends to concentrate towards the bottom of the pile which tends to give a heterogeneous distribution of electrolyte between plates and an uneven distribution of current, but the electrolytic cell built in accordance with the inventin overcomes this.
