Abstract: A finishing machine for the laying of the asphalt surface having a conveyer, and a hopper for the storage and the distribution of material. The conveyer, that moves material from the hopper to the auger, has a couple of chains connected with one another by transversal splines that are suitable for the transport of the material. The material crawls on a plurality of fixed plates secured to the frame of the machine, and the chains run on the plates. The last plate, which supports the passing material, is floating in comparison with the fixed plate which precedes it. The last plate is on a weighing device, and the device is connected with a control power unit. The control power unit detects a signal relevant to the reading of the weight of the material. The signals are detected at time intervals, depending on the angular speed of the hopper, and allows weighings to take place after all the weighed material has been unloaded from the weighing plate.

The cylindrical handle member (60) is fixedly attached to the plurality of support members (30, 40). The handle member (60) transfers a force through the support members (30, 40) to the engagement member (20).

Abstract: An actively controlled rotary steerable drilling system for directional drilling of wells, the system having a rotary drive component rotatable within a tubular sliding tool collar that incorporates elastic anti-rotation members to maintain a coupled relation with the borehole wall during drilling. An offsetting mandrel is supported within the tool collar by a knuckle joint for pivotal movement and for rotation relative to the tool collar and has a lower end extending from the tool collar and supporting a drill bit. To achieve controlled steering of the rotating drill bit, orientation of the tool collar is sensed and the offsetting mandrel is maintained geostationary and selectively axially inclined relative to the tool collar by orienting it about the knuckle joint.

Abstract: A device for cutting filler material from concrete joints comprises a blate attached to the front of an elongated arm, the elongated arm is pivotably joined to a mounting plate. The elongated arm is limited in its movement by a retention bar located on a front edge of the mounting plate and a spring which biases the elongated arm toward the center of the mounting plate. An attachment lip is provided on the front edge of the mounting plate to assist in securing the mounting plate to a bucket of a power machine such as a front end loader. Bolts extending through the mounting plate and a rear turnbuckle also assist in securing the device to the bucket. Mounting is accomplished by placing the mounting plate in the bucket and hooking the lip around the front edge and under the bottom of the bucket. The rear turnbuckle includes a V-plate that engages the top rear of the bucket along the top rear edge.

The pavement edging having an elongated body with a front wall, a rear wall and a plurality of interposed longitudinal and transverse walls forming a generally egg crate construction.

Abstract: A dock leveler mountable in a pit including a rear wall, the leveler including a deck with a front end and that is capable of pivotal movement relative to the rear wall; a lip capable of movement to a substantially coplanar position relative to the deck; and a bumper mounted adjacent the deck front end beyond the lateral width of the lip.

Abstract: A surface seeded exposed particulate concrete method of use includes use of small particulates, the particulates not necessarily chemically inert in the concrete mixture. The particulates are broadcast over the upper surface of the concrete, and mixed into the cement paste derived from the concrete matrix by floats and finished by hand sponging. A surface retarder and vapor barrier are applied, and washing and curing operations follow. The present invention adds a chemical treatment of hydrolyzed alkali silica solution, preferably lithium quartz, penetrating the upper surface of the concrete mixture with minerals and silicates within the concrete mix. The resultant exposed particulate concrete has extreme flatness and high wear resistance suitable for high-traffic flooring applications, aesthetics resembling terrazzo or ceramic tile at a fraction of the price, and the strength and resistance to corrosion expected of concrete surfaces.

Abstract: An apparatus for forming a pattern on the surface of asphalt comprising an endless belt having a surface formed of an elastic material and having a pattern in a form corresponding to a pattern to be impressed into the asphalt. The apparatus includes a belt pressing device, which may be in the form of a weighted roller or plate, for pressing the belt into the asphalt; and a pair of rollers spaced from either side of the belt pressing device, and at a higher elevation with respect to the asphalt surface to provide controlled lifting of the belt from the pressed asphalt. The belt is formed of an elastic material which has little compressibility, so that when pressed down by the belt pressing device, it spreads laterally outward to form pattern elements that are wider than when pressure is released, to provide clean separation from the asphalt surface.

Abstract: An automated weldless inter-locking grating assembly for bridge decks and the like which includes a plurality of primary load-bearing members located laterally, a plurality of transverse secondary load-bearing members and a plurality of trimorphic load-bearing members. Secondary load-bearing structural members are inserted sideways into apertures of primary load-bearing members and trimorphic load-bearing members. Thus, when a horizontal force is applied to alternate primary or trimorphic load-bearing members or any combination thereof, rotation of secondary load-bearing member or members occur to efficiently and automatically lock secondary load-bearing member or members into primary and trimorphic load-bearing member or members completing assemblage thereof into a rigid structural form.

Abstract: A motorized finishing machine has a rotatable guard system enabling it to finish concrete surfaces next to walls, posts, conduits, or other obstacles. Deployed as a concrete trowel, the machine comprises an internal combustion motor that powers a gearbox to revolve a downwardly projecting rotor. Numerous radially spaced-apart finishing blades controlled by the rotor frictionally contact the concrete surface being treated. A protective guard, which circumscribes the rotor, is rotatably suspended by a plurality of rollers. The guard, which is shaped somewhat like a truncated cone, comprises an inner ring coaxially secured above a larger diameter, outer ring. Radially spaced apart spokes extend between the upper and lower rings and brace the guard. The bearing-equipped rollers mounted by radially, spaced-apart arms have upper and lower flanges. The inner guard ring is captivated between the rollers, and it is vertically constrained between the roller flanges.

Abstract: A bucket wheel excavator has a scraper blade mounted on the bogie and whose height is independent of the raising and lowering of the bucket wheel to maintain a level track for the crawler bogie. The scraper blade can be tilted about a horizontal axis by at least one hydraulic cylinder.

Abstract: A safety marker includes an hollow frusto-conical body; a base having an bowl-shaped main portion and a resiliently flexible skirt for yieldably stabilizing the marker against tipping relative to a supportive surface, the body being connected in upstanding relation to an inner portion of the base and concentric therewith, the base being formed to clear the cone defined by the inside surface of the body, the bowl being sufficiently large relative to the body and the base being weighted sufficiently that the marker is self-righting, the skirt being sufficiently flexible to be deflected against the bowl for preserving the self-righting capability of the marker.
