Abstract: Abstract of the Disclosure A process is described for electrolyzing aqueous alkali metal chloride solutions in a membrane cell which contains an anode chamber with the anode and a cathode chamber with the cathode, the two chambers being separated from one another by a cation exchanger membrane.  The cathode is porous and foil-like.          The cathode and cation exchanger membrane form the cathode chamber which is filled with catholyte and the cathode and cell wall form a gas space.  Water is fed into the cathode chamber and alkali metal hydroxide solution is withdrawn from it, hydrogen is withdrawn from the cathode chamber and gas space, and aqueous alkali metal chloride solution is fed into the anode chamber and gaseous chlorine, together with depleted alkali metal chloride solution, is withdrawn from it.  A direct voltage which is at least the same as the decomposition voltage is applied to the cathode and anode.  A higher pressure is established in the cathode chamber than in the gas space.

Title: Automotive radiator cap

Filed: 1987-04-16
Granted: 1992-06-09
Abstract: ABSTRACT            A radiator cap for a filler neck of an automotive radiator tank.  The radiator cap has an inner cap rotatably connected with an outer cap, a pressure valve functionally connected with the inner cap in such a manner that the pressure valve can move vertically so that the pressure valve opens the filler  neck  when the  pressure  within  the  radiator  tank increases up to a predetermined pressure.  The radiator cap further includes a coil spring provided between the inner cap and the pressure valve for biasing the pressure valve toward the filler neck.  Since the connecting point between the coil spring and the pressure valve is lower than the connecting point between a sealing portion of the pressure valve and the filler neck, a rotating moment is generated which returns the pressure valve to a horizontal position whenever the pressure valve becomes inclined, and prevents any tendency to return to an inclined position.  The pressure valve disclosed can maintain its position horizontally and can open the filler neck always at the predetermined pressure.
