Abstract: A road surface crushing apparatus includes: a cylinder-shaped drum configured to be rotatably installed on one side of a main transportation means; a plurality of crushing units each formed to protrude from one side of the outer circumferential surface of the drum in an outward direction, and configured to crush a road surface to be repaired; and one or more cutting units each formed to extend from one side of one of both ends of the outer circumferential surface of the drum in a direction away from the outer circumferential surface of the drum, and configured to cut a boundary surface between the road surface to be repaired and a road surface not to be repaired; wherein when the drum is rotated, both a crushing operation of the crushing units and a cutting operation of the cutting units are simultaneously performed.

Abstract: A snow plow assembly comprising a main plow body, at least one butterfly gate, at least one blocker and a diverter. The at least one butterfly gate and the at least one blocker are jointly connected to the main plow body and are controlled by actuators to be opened and closed. The actuators allow the users to control when to release or hold snow collected into the main plow body. This feature is used to prevent the buildup of high snow ridges in front of small pathways such as driveways.

Abstract: An agricultural tillage implement, including: a frame tube; and a disc blade hanger mounting assembly. The disc blade hanger mounting assembly includes: a disc blade hanger; at least one L-shaped bolt; and an L-shaped clamp, the L-shaped clamp being connected to the at least one L-shaped bolt and clamping the frame tube and the disc blade hanger together by way of the at least one L-shaped bolt.

Abstract: A heavy-duty scraping and rake attachment for excavator buckets for clearing brush-covered earth. The attachment is easily mountable to the bucket, thus avoiding the work and expense of removing the bucket from the arm. The scraper portion provides for offset toothed scrapers, a combination of toothed scraper and blade, and blade only use and is used in conjunction with a heavy-duty rake and power-operated thumb to grasp and remove the material rooted or scraped up from the earth by the scraper. The scraper portion and rake are included in a single unit, attachable and detachable from the excavator bucket. Scraper and blade attachments either detachably connected to the unit with bolts or permanently welded in place as desired.

Abstract: An apparatus for attachment to the bucket of a front end loader, skip loader or any other power-operated bucket. The apparatus comprises a plurality of teeth supported in a frame that attaches to the bucket of a front end loader. The apparatus may be used to sort unwanted material, e.g., small and large pieces of wood, rocks and waste products such as manure, from dirt and then to transfer the unwanted material into the bucket of the loader.

Abstract: A rake attachment and a bucket attachment incorporating the same, the rake attachment generally comprising a plate, a plurality of apertures in the plate and a plurality of teeth. The elongate plate has a plurality of mounting holes extending therethrough and a plurality of integrally formed teeth projecting therefrom. The entire rake attachment is formed from a unitary plate of material to provide strength and durability. The rake attachment is designed to be fixed to the bucket attachment of a loader. Different bucket attachments are produced by various manufacturers and each have differently spaced apertures extending through a lower lip of the bucket. The rake attachment features a plurality of holes that can be combined into many different sets, each set corresponding with the spaced apertures of a specific manufacturer's bucket attachment. As such, one rake attachment can be used with a variety of different bucket attachments for loaders.

Abstract: An attachment assembly is provided for quickly and conveniently mounting a roller onto and immediately ahead of an elongate blade of a road grader or other vehicle which manipulates and moves the blade over a ground surface. The portable roller has an elongate body with a continuous cylindrical outer surface for contacting and working the ground surface, and an axle element about which the roller rotates and which protrudes from each opposed end of the roller body. The attachment assembly is removably receivable on the blade and rotatably holds the roller by the protruding axle element. The location and orientation of the roller relative to the ground surface is controlled by manipulating the blade. The assembly provides an alternative to traditional road grading, namely by allowing a road grader to carry a roller to simultaneously level and compact a ground surface, such as a gravel road.

Abstract: An apparatus for improving the power dissipation of a semiconductor device surface mounted on a printed circuit board having at least a top printed circuit board layer and a bottom printed circuit board layer is provided. The apparatus includes a first pad of metallic material connected to a top surface of the top printed circuit board layer. The semiconductor device is connected to the first pad. A second pad of metallic material is connected a to the top surface of at least one of the top and bottom printed circuit board layers, wherein the second pad is electrically isolated from the semiconductor device. The apparatus also includes at least one thermal via for heat transfer through the printed circuit board layers thermally coupled to the thermal pad. A heat sink is thermally coupled to the at least one thermal via.

Abstract: There is disclosed a new and improved rearwardly folding combination harrow sprayer drawbar. A plurality of quick detach harrow arms are adapted to be quickly connected and disconnected to a plurality of harrow arm receivers. The implement can be used for spraying and harrowing at the same time, or once the harrows are detached and left in the field, the implement can be used for post-emergent spraying. A wet spray boom can be height adjusted by means of a plurality of manual spring loaded levers. The unit is equipped with hinged boom draws which can be pinned to be rigid such that it can be moved rearwardly in order to re-attach the harrows quickly and easily. The unit is also capable of lifting the harrows into a transport position and folding rearwardly into a narrow transport position in order to pass over roads or move through narrow entrance ways.

Abstract: Commercially available seed planters have V-wings mounted immediately in front of the seed openers to sweep clods away and skim off the top player of the bed. However, V-wings are not effective in trashy and sticky soils. The attachment of the present invention is mounted on the V-wing and has downward-rearward directed fingers extending below the V-wing. The fingers push clods and trash away and assist in maintaining uniform depth in all soils.
