Abstract: A branch or other similar article bundler including a central rod, a skid at its forward end and a handle assembly at its proximal end. The handle assembly has a forward molded hand grip coaxial with the rod and a rear twine spool for dispensing twine around a guide in the skid and the guided twine is cleated back on the handle assembly. The bundler with twine looped through the skid guide and cleated back to the handle assembly is slid under the branch pile, the twine end is then uncleated and wrapped forwardly around the branches and tied off adjacent the forward skid guide.

Abstract: An audio-visual EKG monitoring system that segments components of the patient's EKG waveform and synthesizes a plurality of audio driving signals, each representing peak values of the segmented components, and also derives similar peak value signals for driving a CRT bar graph microprocessor.

Abstract: An independently powered mowing attachment for small or medium sized lawn and garden tractors of the low profile type having a rotary mower mounted on the underside of the tractor frame. The attachment has spaced mower assemblies that cut swaths on both sides of the tractor mowers central cut. The mower attachment includes a frame pivotally connected to the tractor drawbar having rear wheels that steer as the tractor turns to assure that the mower assemblies follow and overlap the swath of the leading tractor mounted mower.Each mower assembly is pivotally mounted about a horizontal axis at one side of the attachment frame and has three rotary cutting blades driven by an internal combustion engine mounted centrally on the frame. Two hydraulic actuators are provided for raising and lowering the mower assemblies either simultaneously prior to transort and use, or independently when an obstruction is encountered on one side of the cutting path.
