Abstract: Provided is an adjustable attachment apparatus, system and method, including in various example embodiments a block adapted to rotatably engage a ball portion of an arm, where the arm may be connected with a base that connects with a helical rotatable member. In various example embodiments the ball portion of the arm may “pop” in and out of the block when compressing fasteners in the block are loosened, and the ball portion of the arm may be locked in place by tightening the compressing fasteners, to position the arm and attached structures in any of a variety of positions. In various example embodiments the block may be rotatably mounted to a surface, and the base may be rotatably mounted to the arm, and the helical rotatable member may be pivotally mounted to the base. A plurality of arms may be connected together using one or more double-ended blocks.

Abstract: A stairway having an alternating series of risers and treads wherein two risers and a tread form a step structure for use in constructing the stairway. The step structure including a first riser having a front portion and a rear portion, a tread having a support surface and an opposite surface, a second riser having a front portion and a rear portion, and wherein the tread is positioned between the rear portion of the first riser and the front portion of the second riser and wherein the second riser of one step structure becomes the first riser of the next-up step structure.

Abstract: A support assembly is constructed to support a part-spherical base portion of an object holding device. A cover portion cooperates with the support assembly to capture the part-spherical base portion. The object holding device also includes a mounting post which has a proximal end fixed to the part-spherical base portion and extends radially outward from the support assembly to a distal end on which to attach an object. The support assembly has a piston. Fluid pressure moves the piston member upward which applies a clamping force on the part-spherical base portion to lock the object holding device and thus the object mounted to the post. When fluid pressure is released, a spring restores the object mounting member to an unclamped position where it is freely moveable. Different embodiments employ various combinations of fluid pressure and mechanical springs to lock and unlock the device.

Abstract: A cylindrical body has a first part-spherical socket portion in the top, fittingly receiving a ball. A ball retainer has a second part-spherical socket portion facing the first part-spherical socket portion and receiving the ball therein. A post has a proximal end fixed to the ball and extends radially outward from the ball and away from the body to a distal end, and has screw threads at the distal end to receive a fastener thereon for attachment of an object to the distal end of the post. The ball-in-socket mounting of the post enables freely swiveling the ball and thereby the swiveling the distal end of the post to an infinite number of loci in a spherical envelope centered at the center of the ball, as well as enabling the post, and any object mounted to the post, to be rotated on a radial line from the center of the ball to the location of mounting of the object to the post. The body has a hydraulic cylinder in the bottom receiving a piston.

Abstract: A dispenser is mounted on an X-Y coordinate arrangement of sleeves and guide shafts. It is driven by a motor mounted to a carriage assembly and having a magnetic follower unit driven by the motor and associated with a cam on a support made of ferromagnetic material, the cam being contoured as determined by the pattern of the gasket to be formed by the deposited gasket material. The magnetic follower unit is magnetically attached to the cam support and includes a wheel which is rotated by the motor and drives itself around the profile of the cam as the gasket material is deposited onto a work path of the workpiece. In one embodiment the cam is a chain and the drive wheel is a sprocket gear operating on the chain.
