Abstract: A base supports an inclined screen having a uniform mesh selected to remove larger aggregate from a first cement mixture to form a second cement mixture that passes through the screen. A powered vibrator vibrates the screen to separate the concrete mixtures and larger aggregate. Springs and/or dampers in support legs isolate the vibrating screen from the base. A guide frame on the top surface of the screen guides the first concrete mixture along the screen and guide the separated aggregate out a bottom opening into an aggregate container. A support frame on the bottom surface of the screen stiffens the screen to help support the weight of the concrete. A concrete container, preferably wheeled, is below the screen to collect the second concrete mixture and move it to its use location.

Abstract: A concrete dowel placement system and methods for making the same. The system allows for accurate and easy substantially-parallel or parallel placement of slip dowels within sections of concrete so that adjacent sections of concrete may be allowed to undergo thermal expansion and contraction while remaining in a common plane without cracking or faulting. The system includes a coupler and a sheath. The sheath is configured to be slidably extensible over the coupler and may be held to the coupler by friction. An outer surface of the sheath may be textured. Additionally, a method of constructing the concrete dowel placement system includes extruding material to form two tubes of different sizes. The tubes are then attached to each other, then material is extruded or injection molded to form a sheath. Alternatively, construction may include extruding material to form a tube, then removing some of the material from the tube in order to form a coupler.

Abstract: A concrete surface with a cold joint, dowel slip system and method for forming that surface are provided. Baseplates having tubular projections are fastened to at least one first form using fasteners extending part way into the first form, with the first form forming part of a periphery of a first concrete slab. When the first form is removed, the baseplates, projections and fasteners remain embedded in the first concrete slab. Slip dowels are inserted into the tubular projections and a second concrete is poured adjoining the first concrete slab, with the second concrete embedding the slip dowels, backplates and projecting distal ends of the fasteners and forming a cold joint.

Abstract: A lift for a motorcycle, with the lift being useable with a hitch receiver. The lift comprises a connector engageable with the hitch receiver, and a guide rail having a first end portion coupled to the connector and a second end portion opposite the first end portion. A carriage is operatively coupled to the guide rail and is traversable between a first position and a second position, the carriage moving toward the second end portion of the guide rail as the carriage moves from the first position toward the second position. A platform is coupled to the carriage and is engageable with the motorcycle and capable of supporting the weight of the motorcycle when engaged therewith and as the carriage is moved from the first position toward the second position, causing the motorcycle to be lifted from the ground.

Abstract: A concrete dowel slip tube assembly is provided for use in maintaining a planner consistency of a cured concrete slab formed on a support surface. The assembly comprises a plurality of elongate slip tubes, each having a length dimension and a tubular hollow interior compartment. Dowels are slidingly engageable to the hollow interior compartment to allow for translation along the interior compartment. A support frame defines a plurality of integral slip tube retaining members, disposed at evenly spaced locations along the support frame, the retaining members being configured to receive and engage associated slip tubes to the support frame in a common defined orientation. The support frame and the retaining members are formed as a unitary construction.

Abstract: A decorative concrete with a very uniform finish surface and a method of fabricating the same is disclosed. A concrete mixture is poured over a subgrade which defines an exposed surface. The exposed surface is finished with any of several techniques, and the surface is then worked with an abrasive material, and additional techniques are used to color and seal the concrete.

Abstract: A method of forming an architectural concrete structure having a desired look (i.e., color) and texture, wherein the method generally includes pouring a base concrete layer using conventional concrete. A surface concrete mixture is prepared and includes a mixture of sand and small aggregates to give the surface concrete mixture the desired color and texture for the architectural concrete structure. The base concrete layer provides strength and durability to the concrete structure, while the surface concrete layer provides the desired look and texture of the concrete surface. The surface concrete mixture preferably includes small aggregates to create a smooth and uniform texture.

Abstract: A dowel placement system including a fastener configured to be engageable with a form, and a radially compressible bushing coupled to the fastener and defining an adjustable outer diameter. The system further includes an elongate dowel sleeve having opposed proximal and distal end portions, and an axial opening having an inner diameter and extending into the dowel sleeve from the proximal end portion to the distal end portion. The bushing is insertable within the axial opening of the dowel sleeve, and the bushing and dowel sleeve are configured such that insertion of the bushing within the dowel sleeve causes the outer diameter of the bushing to compress and conform to the inner diameter of the dowel sleeve and to create a friction force between the bushing and the dowel sleeve to mitigate movement of the dowel sleeve relative to the bushing during formation of the concrete structure.

Abstract: A slip dowel tube and elongate dowel are disclosed herein which allow for transverse and longitudinal movement of two adjacent concrete slabs and also limit vertical movement of the two concrete slabs. The slip dowel tube is housed within a sheath that provides a void to allow for transverse movement of the slip dowel tube when the first and second slabs move transversely with respect to each other. The elongate dowel is slidably disposed within the main tube to allow for longitudinal movement or movement which brings the two slabs closer to or further away from each other. This system also limits vertical movement between the two adjacent slabs.

The method further includes providing an elongate irregular surface forming tool having a gripping portion and a distressing portion defining an irregular configuration. The exposed surface is repeatedly struck with the distressing portion of the irregular surface forming tool to define an irregular surface.
