  • Ion vapour deposition apparatus and method
    Patent number: 5660693
    Abstract: Spectacle lenses are coated by ion vapor deposition by means of sputtering target materials. A plurality of lenses to be coated are introduced into a sputtering chamber by a load lock device, and when in the chamber the lenses are covered by a disc which is rotated at high speed (50/60 rpm). During this rotation alternate targets of magnetrons are sputtered releasing metal particles which are oxidized by an oxygen plasma created by a third magnetron and metallic oxide coatings are formed on the lenses as alternate layers of different materials. At the end of the operation of coating, which is pre-programmed, the lenses are returned automatically to the load lock device from whence they can be removed. After placement or the lenses in the load lock device the entire process is effected automatically by pressing a button.

  • Apparatus for holding open a door or the like
    Patent number: 4053961
    Abstract: Apparatus for holding open a door or similar closure member for a limited period, which may be predetermined, whereupon the door is automatically released and is able to return to its closed position, includes suction means for attachment to the door and/or surface against which the door is to be held in face-to-face relationship. The period of time during which the suction means is active may be determined by means of an air leakage to the suction means, or by means of a spring acting against the suction means.

  • Catalytic process
    Patent number: 3939104
    Abstract: In a supported catalyst for treating internal combustion engine exhaust gases the active material comprises a non-noble metal or compound thereof and the support comprises a primary support carrying a secondary support; the secondary support consists essentially of one or more involatile acidic and/or amphoteric oxides substantially in combination with one or more basic oxides from Group II, III or IV of the Periodic Table. A platinum group metal may also be present. The catalyst can be used for reductive or oxidative treatment or for simultaneous reduction of nitrogen oxides and oxidation of carbon monoxide and hydrocarbons and exhibits high activity and long life.
