Abstract: A viscous fluid shear clutch comprises a two-part outer casing 14,15 and an inner clutch member 10 between which is defined a clearance gap into which viscous fluid may flow to provide an adjustable degree of coupling between the casing and the clutch members. Fluid is continually pumped out of the gap by a circumferential scoop pump. The clutch may be assembled for reverse operation by indexing the casing parts relative to one another. The quantity of fluid in the gap may be controlled dependent on sensed temperature and sensed speed or sensed temperature alone. A thermo pressure valve provides a pressure force related to the sensed temperature; this relationship may be inverse for failsafe operation.

Abstract: An apparatus for cleaning escalator steps having grooved front surfaces cleans during the operation of the escalator. A brush extending across the entire width of each step is positioned under the rear edge of the tread. The bristles of the brush press against the front surface of the adjacent step when the steps are in predetermined regions of the escalator.
