Abstract: The present invention is a wireless electronic control device, primarily intended to be attached to the impulse valve of a Hydraulic Ram Pump (‘HRP’), enabling remote automatic and manual management of the HRP. The Electronic Ram Pump Controller (‘ERPC’) may be used to control the HRP, through the restriction of the fluids entering/or exiting the pump. In the presented form, the Impulse Valve Manager (‘IVM’), attaches to an impulse valve and restricts, to a varying degree, the aperture size of the impulse valve. Through this control mechanism the HRP may be sealed, started, or tuned—either remotely by a user or automatically through the ERPC's automated systems. The presented version can be augmented with valve actuation and sensing of the impulse cycle. The ERPC may be retrofitted or incorporated into the design of a new HRP.

Abstract: A motor control system is presented. The motor control system includes a motor controller and a motor driver. The motor controller and motor driver are coupled by an interface which includes a conductor configured to carry both a motor speed control signal from the motor controller to the motor driver and a motor feedback signal from the motor driver to the motor controller. The motor controller provides a motor speed control signal to the motor driver and the motor driver provides a motor feedback signal to the motor controller.

Abstract: The present invention provides a furniture assembly that includes rods and connection members, and that can be fully assembled without using tools or additional hardware. In one embodiment, the rods include a threaded end and an unthreaded end, and the connection members include an interior member and an exterior member, where the interior member and exterior member may be separate or of unitary construction. The exterior member includes unthreaded apertures for receiving the rods and the interior member includes an unthreaded aperture and a threaded aperture, also for receiving the rods. The rods and connection members are interconnected and gradually tightened to provide a stable furniture frame. Multi-level framing and methods of assembly are also provided. In an alternate embodiment, a connector assembly is provided for securing a plurality of rods within a connector using a leg threaded into the connector obliquely to a plane occupied by the rods.

Abstract: A device for flushing out a clogged drain of a household plumbing system; the device including a long flexible plastic tube which at one end is inserted into the drain and which at its other end is attached to a faucet, a plastic sleeve around the tube forming a seal at the drain opening and an additional grommet being selectively used around the sleeve so to seal a basket sink strainer.
