Abstract: A vector brush can be attached to the front face of a movable carriage of a device for cutting foil material. The vector brush includes an air brush, which can be adjusted in height, thereby adjusting the size of its atomizing cone. The motion of the air brush is controlled by the motion of the carriage in one direction and the motion of the foil strip moved underneath it in the perpendicular direction. After a pattern has been sprayed on the foil material with the vector brush, it can immediately be cut out with a cutting tool mounted on the same carriage.

Abstract: A tool guiding measuring apparatus or apparatus for measuring a portion of a workpiece and guiding a tool during an operation on the workpiece. The apparatus includes an aligning body portion for positioning the apparatus in a desired orientation against a workpiece. Two tapes are provided on the aligning body portion for measuring the dimension of a portion of the workpiece. A selectively positionable clamp on a free end of the tape is used to calibrate the apparatus to provide a true measure on the tape of the dimension of the workpiece while compensating for the dimensions of the apparatus and tool. The selectively positionable clamp securely attaches to each of the tapes at a desired calibration position on the respective tape to provide ease of use and repeatable measuring. The apparatus also includes a clamping device which clamps the apparatus to the workpiece to prevent movement of the apparatus while cutting.

Abstract: A method and system for measuring a profile of a strip of material produced in a reversing mill in which a direction of travel of the strip is reversible includes a single thickness gauge that measures the thickness of the strip and generates the thickness signals, and a moving device coupled to the gauge. The moving device controllably moves the gauge transversely to the strip so that the gauge measures the thickness of the strip and different points across a width of the strip in one pass of the strip through the gauge. The moving device maintains the gauge in a stationary position in another pass of the strip through the gauge such that the gauge measures the thickness of the strip and different points along the longitudinal lines of the strip. The measurements of the thickness of the strip at the different points are interpreted into profile data. This profile data can be either displayed or used by a mill computer to control the processing of the strip.

Abstract: A sideslip tester detects sideslip and scrub in a vehicle having a steering axle and one or more pairs of tandem axles. The sideslip tester has a runway having a measurement plate which is moved laterally with respect to its longitudinal axis as a tire of the vehicle passes over the measurement plate as a result of lateral forces acting upon the tire. A lateral movement sensor operatively connected to the measurement plate determines the amount of lateral movement of the measurement plate as the vehicle tire passes over the plate and provides an output corresponding to the amount of lateral movement measured. The sideslip tester can determine when it is presented with tandem axles. When it is presented with tandem axles, the sideslip tester will determine the scrub angle of the tandem axles to determine if they are parallel.

Abstract: An integral angle measurement device employs a printed circuit board having electronic components mounted on the front surface thereof and having a pair of sensor plates etched into the back surface thereof. Containment of the sensor fluid adjacent the sensor plates is accomplished by soldering a sensor cover to an etched sealing ring on the back of the circuit board. The sensor plates etched into the back of the printed circuit board, in combination with the sensor fluid, act as variable resistors whose resistance changes as a function of their angle of rotation from a reference position. An output signal across these variable resistors is in or out of phase with an applied reference signal. The output signal is demodulated with the same reference signal and then filtered to a DC level that corresponds to the angle of rotation. An output stage serves as a driver and also as a means for permitting the user to remotely control the electronic gain of the angle measurement device.
