Title: Filter for fluids, with porous cylindrical filter - has element in partitioned chamber, allowing uninterrupted flow during replacement
IPC: B01D35/147
Filed: 1977-02-21
Abstract: New filter for fluids comprises a porous cylindrical filter element through which the fluid flows upwards and radially, passing through the side wall of the element. The improvement is that the filter incorporates a vertical perforated cylinder, sepd. into two compartments, one over the other, by a horizontal partition. The filter element is placed in the periphery of the lower chamber. A spring loaded valve in the upper compartment normally closes a hole in the horizontal wall. The spring exerts a press. slightly above the fluid press. When the filter element becomes clogged, the fluid press. increases and opens the valve, allowing the fluid to enter the upper chamber. Design renders it unnecessary to stop the operation while the filter element is being changed. The fluid flow continues without interruption, but along two different paths according to the state of the element.

Title: Attitude control of space vehicle - utilises kinetic moments from rotating wheels also used to store energy
IPC: B64G1/28
Filed: 1978-04-18
Abstract: Attitude control of space vehicle is performed utilising exchange of kinetic moments between rotating wheels and the body of the vehicle. Wheels also permit storage of energy without degrading control performance. Identical contrarotating wheels are coupled to motors and generators. A switch permits connection of generators to a bus bar and torque control is effected by a detector sensing voltage difference relative to a reference voltage. The error signal is corrected and amplified to control the motor generators. Tachometer outputs are processed for calculation circuit. Input from the attitude sensor enables the calculator to determine the resultant kinetic moment for attitude control.
