Abstract: A window bird feeder. In a described embodiment, a window bird feeder includes a bird feed storage compartment bounded by an arch fastened to a base. The arch has openings therethrough for dispensing bird feed from the storage compartment onto the base. A rail on a front wall of the storage compartment separates a bird feed dispensing area of the base from a bird positioning area of the base. An upper lip and a lid of the bird feeder are configured for ease of filling the storage compartment.
Abstract: A liftable independent suspension system which may also be steerable. In a described embodiment, a liftable suspension system for use on a vehicle includes wheel spindles positioned to extend outwardly at each respective lateral side of the vehicle. The spindles are displaceable independent of each other. An actuator is operable to raise at least one of the spindles, so that a tire rotatably connected to the spindle is liftable out of engagement with a road surface when the actuator raises the spindle.

Abstract: A sequential hydraulic well control system provides actuator selection and operation utilizing pressure applied to hydraulic lines in a sequence. In a disclosed embodiment, an actuation control device of a well control system includes multiple pistons, at least one of which is included in a latch for selectively permitting and preventing displacement of another of the pistons. When one of the pistons displaces in response to pressure applied sequentially to hydraulic inputs of the control device, an associated actuator is placed in fluid communication with the inputs.
