Title: Disc filter with internal cleaning - using curved double sided brushes which rotate between filter surfaces
Inventor: ARVANITAKIS KOSTAS SAVAS
IPC: B01D33/23
Filed: 1976-10-18
Abstract: Cleaning of disc filters to remove sludge, spent cake etc. from their surface consists of a curved arm which can be rotated in the space between adjoining discs. The upper and lower surfaces of the arm have flexible and elastic projections which contact the filter surface. This elastic part forms in effect a brush which causes its components to move across the filter surface when the arm is moved. In this way an effective but relatively gentle cleaning action is achieved. The shape of the arm ensures that sludge so removed is propelled to edge of the disc, where it can fall off into a sump, etc. Used to clean filter disc filters for pressure filtration. The system permits effective cleaning without opening the filter and without damaging the filter medium or reducing its filtration efficiency.

Title: Camera aperture setting control - uses electromagnet and photoresistive cell to position aperture lever in one of two possible positions
Inventor: WAGNER KARL DIPL ING DR
IPC: G03B7/083
Filed: 1977-02-28
Abstract: The setting control for a camera aperture uses a control lever in conjunction with electromagnets to move the aperture setting between one of two possible positions. The yoke lever of the electromagnets is rotable about the control lever, the latter being spring loaded. The mechanism is arranged so that the weight of the shutter closure device is greater than the difference between the tractive force of the electromagnets and the spring force. The aperture control mechanism is also controlled by a photoresistive cell responsive to brightness of incoming illumination, because the resistance of the cell is incorporated in a battery circuit with a coil working in conjunction with one of the magnets.
