摘要： This invention relates to floor treatment machines, e.g. for scrubbing and polishing floors comprising a pair of driving wheels with independent speed control, a pair of independently movable manually operable control members mounted side-by-side on the machine, with each of said control members being operably connected to an individual electrical component forming part of the speed control for one of the driving wheels, whereby synchronized movement of the control members provides equal adjustment of the wheel speeds, whereas differential movement of the control members provides a steering effect. When operated by a walking operator, such machines have been found to exhibit a tendency to hunt for a selected speed, and in order to avoid this damping means is provided between the operator's control and the electrical components to reduce the sensitivity of the mechanism.

摘要： A cyclone is provided above a liquid receptacle (4) in a housing (1,3) whose interior is at reduced pressure in operation. Liquid and solid particles carried by the incoming stream of air accumulate in the cyclone (18) and circulate as a body of solid-laden liquid while coming repeatedly into contact with the incoming stream. Excess solid-laden liquid flows down into the receptacle (4) from the cyclone (18) through a lower outlet (23a). The air leaves the cyclone substantially freed from liquid droplets and solid particles.

摘要： A floor treating machine, particularly for scrubbing or polishing a floor is provided with a recording and replay device for the power supply to the traction motors so that it may be programmed to repeat a pattern of movement automatically. In order to provide constant and periodic checks on the accuracy of the repetition over long straight runs, there is provided a distance check device for comparing the distance run in operation with the distance run on recording, and means for correcting the path should discrepancies arise.

摘要： According to the invention there is provided a floor treating machine having laterally spaced drive wheels driven by separate electric traction motors under electronic control so as to be driven by separate train of pulses, comprising means for recording the trains of pulses to the traction motors and means for replaying the record to reproduce the trains of pulses whereby the machine will repeat the operation. When replaying the record it is normally necessary to provide course correction by means of sensing devices for sensing the presence of a wall or other physical obstruction and further sensing devices for sensing the presence of unscrubbed floor, and means for providing overriding control by signals from the sensing devices.
