Title: Mobile crane electronic overload warning system - has detectors for centre of gravity movement in any direction
IPC: B66C23/90
Filed: 1973-11-07
Abstract: The safety and warning system is designed to allow maximum use of the capacity of a crane, excavator etc. as regards radius, and detects movement of the centre of gravity in any direction when the chassis is tilted, the result being fed to two separate measuring devices. Typically, this can be effected by pendulums, spirit levels etc. with tapping devices such as potentiometers, rotary capacitors, inductive angle indicators, photo-diodes or contacts. Power absorption devices can also be used. The angle of jib inclination can also be detected and fed to the measuring equipment, which can also evaluate the ratio of chassis length to width, and the tipping moment. The equipment can be arranged to release pump pressure and/or disengage the clutch if any of the indicator devices fail, and also a set number of seconds after the sounding of the alarm signal.

Title: Rotating sewage sludge vacuum filter - using second endless filter ribbon for passage through ganged pressure rolls
Inventor: VOIT KARL
IPC: B01D33/00
