IPC: A01B1/16
Filed: 2002-05-21
Abstract: A garden tool with a non-slip handle grip, designed for immediate and not difficult removal of deep-rooted plants such as Thistle and Dock weeds. The body of the tool is of rigid and strong construction, with angled cutting faces and includes a plant/soil containment chamber. The tools angular cutting faces and profile, are designed to produce efficient insertion and soil compression when downward thrust is applied, which therefore holds captive the plant root in the containment chamber, hence achieving successful plant removal from the ground when the tool is withdrawn.

Title: Differential length metering apparatus and method for the cabling of insulated conductors with fillers using the double twist process
Inventor: WHITE PAUL
IPC: H01B13/02
Filed: 2000-11-29
Abstract: Apparatus and method for manufacturing helically wound insulated conductors with filament fillers includes first and second payoff stations for paying off a plurality of insulated conductors and elongate filaments of filler materials. These cable components are guided from the payoff stations to a closing die, and are arranged in positions suitable for twisting into a cable by a double twist machine to form a cable of twisted insulated components forming radially outwardly facing helical interstices each of which is substantially filled with another one of the filaments of filler material. Differential or incremental lengths of filler material are metered upstream of the double twist machine to compensate for the differences in the radial distances of the insulated conductors and filaments of filler material on the center or cable of the axis. In this way, the helical interstices are more fully filled and the resulting cable has an exterior surface with minimal voids so that covering of the resulting cable with an outer elastomeric jacket or coating results in a substantially smoother and aesthetically pleasing cable with minimal surface irregularities.
