Title: Prodn. and storage of fermentation gas - from cellulosic waste under pliable fabric or plastic dome
IPC: C12M1/107
Filed: 1977-01-04
Abstract: Prodn. and storage of gas, produced by the anaerobic fermentation of cellulosic waste under water is efected in a tank covered by a pliable dome erected in the open air. The dome is made from a fabric, which is impermeable to gas, or from a plastic film it is adapted to the shape of the tank by suitably arranged folds and an adhesive, or is sewn with waterproofed thread. Its periphery is fitted into a gutter formed in te summit of the tank walls and is made rigid by iron or plastic tubes; this gutter is filled with water. The dome can be folded back when charging or discharging the tank. To avoid the formation of a crust, which would inhibit gas prodn., liq. is withdrawn from the base of the tank and distributed over the surface of the material by a row of sprinklers (3) around the periphery. At the start of the operation seeding bacteria can be introduced through the sprinklers to cause a rapid start to the fermentation. The temp. in the tank can be increased by passing the liq. through a heat exchanger (4) where is its heated by the boiler or by the cooling system of an electric generator. To increase the gas pressure, steel plates or concrete slabs can be laid against the pliable dome. Very large tanks can be made at a low cost and provide direct access to the charging and discharging vehicles. The gas produced during the night is stored under the dome for use during the following day.

Title: Rotor head for helicopter - has coaxial counter-rotating sets of blades of different lengths to reduce deflection
IPC: B64C27/10
Filed: 1977-10-12
Abstract: A helicopter has two co-axial rotors rotating in opposite directions in order to cancel the driving torque and so eliminate the need for a tail rotor. In order to reduce the height of the rotor head the blades (P1) of the upper rotor are shorter than the blades (SP2) of the lower rotor. With these shorter blades there is less deflection and so there is no risk of contact between the upper and lower blades with a compact rotor head. In addition the aerodynamic interference between the rotors is reduced with a consequent increase in efficiency of propulsion.
