Abstract: A universal tram is provided for aligning machine tools. The universal tram includes a slide rail, featuring a rail along its length, to which a clamping coupler attaches. In turn, the clamping coupler attaches to the indicator holder. The indicator holder is configured to hold an indicator. The slide rail is configured for direct attachment to horizontal and vertical milling machines, for example. Optionally, the universal tram also includes a machine adapter and adapter plate.

Abstract: Various aspects of tape measures with one or more of a sensor, a motor, and a clutch, are shown. The sensors described herein detect, through various mechanisms, the position of the retraction system of a tape measure. The measurements by the sensors may be used to control a motor to adjust an amount of tension in the spiral spring of a tape measure. In various embodiments a motor interacts with the retraction system of the tape measure via a clutch, which moderates an amount of force that the motor can communicate to the retraction system.

Abstract: The invention relates generally to a system used to produce a prototype part and subsequently an accurate design specification for a fluid or gas handling system/hose and or tube assembly, followed by the subsequent communication of that specification into an ordering interface that processes the specification into a usable format as a means to accurately produce and re-create the original specification in a remote location by a specific manufacturing process, in order to supply the originator of the design an accurate, working part, produced in the specified materials in a rapid, convenient and cost effective manner. The process has global applications in various industries, markets and vehicle or machinery types, particularly where it is inconvenient or prohibitively expensive to have the work performed on-site by a technician.

Abstract: A digital linear measuring device that digitizes the length of the extended tape and displays this measurement on a primary display screen that continually updates to a current measurement. The user can decide when to save a measurement, at which point the saved measurement will appear on a secondary screen (either a portion of the primary display, or a secondary adjacent display) as a previously taken measurement. These measurements can account for both an external measurement read from the tape measure, as well as an internal measurement, and the measurement may be adjusted where necessary to take into consideration the length of the device body. In use, there is no need to write down or remember a previous measurement, as they are displayed and easily accessible.
