Methods and Apparatus to increase the efficiency of roll-forming and leveling systems are described herein. An example strip material processing apparatus are described herein includes a first drive system to drive a first plurality of workrolls and a second drive system to drive a second plurality of workrolls. A controller provides a first command reference to the first drive system. The controller measures a first output parameter of the first drive system when the first drive system operates at the first command reference. The controller determines a second command reference based on the first output parameter and the controller drives the second drive system based on the second command reference.

A novel conduit design is disclosed. The conduit includes a cylindrical body having defined therein a first aperture and a second aperture, wherein the first aperture is designed to receive a shaft of a turbine and the second aperture is sufficiently large to facilitate ingress or egress of a probe through the second aperture, and wherein the second aperture is located a distance away from the first aperture such that when a turbine is disposed through the first aperture, an entry by a probe into the cylindrical body through the second aperture is not prevented by presence of the turbine.

The present invention is an improved lighting system. In particular, the present invention is directed to an LED lighting system with replaceable circuit boards. The lighting system comprises a printed circuit board with a set of LEDs on top and two electrical contact surfaces on the bottom that snaps into a module assembly. The module assembly has an exterior element with two contact windows on its surface with a set of fingers extended to hold the circuit board to two electrical contacts. The electrical contacts pierce two electrical leads inside channels in an interior element of the module assembly.

An armature for use in an electric traction motor comprises a rotor having a central portion and a peripheral portion with the peripheral portion having a plurality of cavities. Permanent magnets solidified from liquid magnetic material are disposed in the cavities to form poles of the rotor with at least a portion of the cavities having directly abutting permanent magnets comprised of at least first and second magnetic materials of different properties injected in liquid or mobile form into single cavities. In interface regions between the at least first and second magnetic materials the first and second magnetic materials are intermingled to form a transition zone. A method of making the armature includes injecting the magnetic materials simultaneously as well as injecting a subsequent magnetic material when the initial magnetic material is still fluidly mobile.

An apparatus for measuring, leveling, securing and plumbing. The apparatus contains a slide element slidably mounted to a body element. The body element is fixed to a base element. The slide element defines a viewing channel for viewing a side level fixed to the body element. The slide element has a pair of longitudinal trapezoidal rails fixed to the back of the slide element and running its length. The body element has a pair of longitudinal trapezoidal channels along the front of the body element. The channels within the body element receive the rails of the slide element to slidably fix the slide element to the body element. The slide element may be moved along the body element to a set position, the apparatus aligned, and the slide element locked into place for measuring or plumbing.

An integrated straw and container. The container includes an interior bottom surface and defines an opening near an upper portion of the container. A cap can be placed onto the container to close the container, and then removed to open the container. The straw includes a shape that operates as a spring operates to create two states: a resting or expanded state and a compressed state. In the resting state of the straw, the overall distance from the first end to the second end is greater than the distance from the interior bottom surface of the container to the opening of the container. The straw is placed into the container and the container is sealed forcing the straw into a compressed state. Upon removal of the cap, the straw returns to a resting state in which the upper end protrudes from the container opening.

A guide for assisting in marking a measurement and/or scoring a sheet of drywall, paneling or other planar building material has a bore for receiving a pencil or other marker and has a slot for receiving a scoring blade therethrough. The guide may have a support for maintaining the pencil, marker or a knife having a scoring blade, in a steady relationship with the surface to be scored or marked. The guide may have a curvature or curvatures for cooperating with the pencil, marker or knife. The guide may also have an attaching structure, such as a flange or slot, to attach the guide to a measuring device, including a retractable carpenter's tape, combination square or other rule.

The present invention is directed toward a method of that provides a user with the ability to choose the combination of dye species that best fits his or her application. Users can create prints that are colorful, lightfast, or some combination of these two. In one embodiment, the invention takes into account the characteristics of the printing medium and determines from that information how to optimize the lightfastness and gamut of an image. Lightfastness and gamut tend to relate inversely, in that the better the lightfastness, the worse the gamut and vice versa. The lightfastness and gamut of an image can be altered by changing the colorants used to print the image. High-chroma inks produce images with high gamut values. Conversely, images printed with low-chroma inks have increased lightfastness. An embodiment of this invention uses the characteristics of the print medium, upon which the image will be printed, to optimize the tradeoffs that exist between lightfastness and gamut. In this embodiment the relative amount of high- and low-chroma ink varies depending upon the characteristics of the print medium.

A stretchable string (100) having a first cross sectional diameter at rest and a second smaller cross sectional diameter when stretched. An aglet (200) positioned on the string. The aglet has an inner cross sectional diameter that is smaller than the cross sectional diameter of the string at rest and approximate to the cross sectional diameter of the string when it is sufficiently elongated. The aglet is moved along the string when the string is sufficiently elongated. The aglet can be repositioned along the string by stretching the string such that the diameter of the string is approximate to the inner diameter of the aglet. Excess string can then be removed.
