20160137500 | MODIFIED SULFUR, METHOD FOR PREPARING SAME, APPARATUS FOR PREPARING SAME, AND USE THEREOF - Disclosure relates to modified sulfur, preparation method thereof, preparation equipment thereof. The modified sulfur has spinnability or includes micro-structures such as fiber-, film- and network-like structure. The modified sulfur can be prepared by inducing polymerization with ultrasonic or ageing. The modified sulfur has various excellent features such as anticorrosiveness, waterproofing, strength, and fast drying and can control the features depending on its viscosity or polymerization degree. In addition due to the above features, the modified sulfur can be applied to anticorrosive or waterproofing material and can prepare anticorrosive or waterproofing material which has good workability, hardening, salt spray resistance, and weldability exceeding a certain level, and specially improved adhesiveness. Furthermore, when applying the modified sulfur to asphalt composition, gelation and depression are reduced, properties such as bending strength and tensile strength are improved, and it is possible to obtain asphalt composition with good working stability at RT. | 05-19-2016 |

20090293698 | SAW BLADE HAVING TEETH WITH VARYING DEPTHS AND ALTERNATE TIP BEVELING - A saw blade for improved cutting efficiency includes teeth having depths and tip-to-tip spacings that vary as a function of distance from an end of the blade to the tooth, the teeth extending from the plane of the blade at alternating angles and having a recurring pattern of alternate tip beveling. | 12-03-2009 |
20110113635 | PRUNING LOPPER WITH AN ADJUSTABLE ATTACHMENT MECHANISM - A pruning lopper with an adjustable attachment mechanism to provide for versatile cuts of tree branches and shrubs. The attachment mechanism is a ball joint that can rotate in an x-direction, a y-direction, around the axis of rotation of the pole, or any combination of the three. A pulley system internal to the pole prevents entanglement with tree branches while in operation. | 05-19-2011 |
20120279072 | MULTIPLE CUT ZONE BLADE ASSEMBLY FOR A HAND OPERATED CUTTING TOOL - A hand pruner having a first and second handle, the first handle having a hook, formed at a far end, the second handle having a cutting blade formed at the far end. The first handle and hook and second handle and blade pivotally connected for movement with respect to each other. The blade and second handle having a cup formed between the blade and second handle. The hook and first handle having a cup formed between the hook and first handle. The cutting edge of the hook is formed along two concave intersecting arcs of different diameters, the smaller diameter arc located next to the pivot. The cutting edge of the blade is formed along two convex intersecting arcs having diameters that complement the two concave arcs in the hook cutting edge. | 11-08-2012 |
20150048174 | Sprinkler Arc Adjustment Mechanism - The present invention is directed to a rotor or sprinkler that allows its watering arc to be rotated, increased, or decreased by user-rotation of the sprinkler's rotating nozzle base. | 02-19-2015 |
