Abstract: An input device can include a housing defining an internal volume and a lower portion, the lower portion defining an aperture, an input sensor disposed in the internal volume, and a haptic assembly disposed in the internal volume. The haptic assembly can include an actuator and a foot coupled to the actuator and aligned with the aperture. The actuator can be configured to selectively extend the foot through the aperture to vary a sliding resistance of the input device on a support surface.

Abstract: A process for recovering edible oil and bleaching clay from an edible oil-bleaching clay waste stream and for recovering edible oil and nickel catalyst from a hydrogenated edible oil-nickel catalyst-filter aid waste stream; the recovered bleaching clay may be reused directly and the recovered nickel catalyst and filter aid mixture is pelletized for metallurgical nickel recovery.

Abstract: A burner apparatus provides on-site destruction of waste liquids such as liquid anti-freeze, waste motor oil, and the like independently of the liquid concentration thereof. The apparatus comprises a storage tank for waste liquid including a reservoir and a level sensor for sensing the level of the waste liquid in the reservoir, and a burner unit energized responsive to the level sensor when the level of waste liquid exceeds a predetermined value. The burner unit includes first and second chambers connected together by a flame port provided between the chambers at the bottom of the chambers. An atomizing injector injects waste liquid from the storage tank, in an atomized form, into a flame produced by a first burner located at the top of the first chamber so that combustion products that are produced fall towards the bottom of the first chamber and pass through the flame port into the second chamber. A second burner burns combustion products exiting from the flame port into the second chamber.
