Abstract: An alfalfa valve telemetry system for regulating irrigation fluid to an irrigation-dependent field provides an alfalfa valve that operates over an opening to a fluid supply pipe in a field, so as to selectively discharge fluid to the field. The alfalfa valve telemetry system provides a telemetry-controlled valve actuation assembly that axially or pivotally displaces the alfalfa valve between an open position and a closed position over the opening in the pipe.

Environmental sensors and fluid sensors in the field communicate data signals with a primary controller that controls the valve actuation assembly. The position of the alfalfa valve is based upon the data signals received from the sensors, indicating fluid levels, fluid flow rate, and environmental conditions on and near the field.

Abstract: A valve actuator having a pivotal cam-lever driven push-pull mechanical linkage system. A power mechanism moves a cam-lever member which then moves a connecting rod to move a push-pull member to lift out or push in a conventional valve stem. This then opens or closes the valve. In an alternative embodiment, the actuator includes an adjustable block member to which the cam-lever is pivotally attached. This provides a separate adjustability for the ultimate maximum movement of the push-pull member and thereby also of the valve stem in order to ensure a proper closing force is imparted to the valve. Also in this embodiment, it is preferred that the push-pull member includes at least one spring washer disposed therein. This provides a desirable compressibility in the system during the imposition of the force that the push-pull member exerts on the valve stem during the opening and/or closing process.

Abstract: A drive means for an oscillating spout is presented which includes a control mechanism which directs a control arm to perform the movement required by the spout and a transmission device which acts to transmit the control arm movement and reproduce it as spout movement. The control mechanism consists of a driving rod pivotally connected to an intermediate lever arm and a universal joint connecting the lever arm to the control arm. A novel movable torque means is associated with the universal joint and enables the spout to be moved in and out of a vertical orientation by overcoming the tendency of the components of the control mechanism to become axially locked in a 180.degree. angle. The movable torque means accomplishes this result by reducing the angle between the intermediate lever and control arm when that angle reaches 180.degree..

Abstract: The invention relates to a braking mechanism for braking the chain of a portable power chain saw when a hazardous state occurs. The operating lever rotatably mounted on the chain saw casing is in operative connection with a control lever acting on a brake band by means of a lever-like device. Thus, in the braking position the control lever is transferred into an angular position with a simultaneous position change of the two brake band articulation points. As a result, the brake band is applied to the brake drum, which ensures that the braking mechanisms act without any delay.
