Patent number: 6829944Abstract: An apparatus and method for measuring the tension in bolts, screws, rivets, and other fasteners, is disclosed wherein the deformation of the fastener head is measured, (or the end of fastener in such cases as there is not a distinct formed head, for example stud bolts). The deformation generally is an analytic function of the tension in the fastener. The deformation is a continuous two-dimensional distribution over the surface of the fastener head, which allows redundant measurement and therefore more reliable measurement of fastener total axial tension, and also allows in some instances an evaluation of the bending stresses in the fastener from the distortion of the deformation pattern on the head. An advantage of the invention is that the length of the fastener or its temperature need not be known. The measurements can be determined by optical, capacitance, optical imaging, air gauging and piezoresistive techniques.Type: GrantFiled: October 8, 2002Date of Patent: December 14, 2004Inventors: Stuart M.

Patent number: 6829948Abstract: An input unit for receiving a signal from an oscillator corresponds to an ultrasonic wave received by the oscillator has an input impedance significantly smaller than an impedance of an inter-electrode capacitance in the oscillator. This arrangement allows the delay of timing of the received wave to be influenced by a change in the input impedance of the input unit than by a change in the impedance of the oscillator. Since the influence of the change in the impedance of the oscillator against the delay of timing of the received wave is reduced, a flow meter can measure a propagation duration of the ultrasonic wave accurately. More specifically, the flow meter can measure the propagation duration accurately regardless of a change of the inter-electrode capacitance of the oscillator by temperature, thus measuring a flow rate of fluid correctly.Type: GrantFiled: March 13, 2003Date of Patent: December 14, 2004Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yuji Nakabayashi, Shuji Abe

Patent number: 6829971Abstract: An improved cutting fixture for heat-shrink film sleeve labeling machines comprised of a mounting frame disposed around the outer periphery of the center guide post in a sleeve labeling machine that secures a plurality of blade assemblies at equal intervals apart. Each blade assembly is positioned on a drive plate by means of an inserted eccentric shaft to maintain synchronous operation. The eccentric shafts of the blade assembly are driven into reciprocal rotation by a power structure, each eccentric shaft causing the blades at their lower extents to alternately project and retract for cutting heat-shrink film at a required travel and time to effectively shorten the period involved and thereby increase production efficiency. Each cutter shaft is restrained by a check plate and anchoring screws to prevent 360 -degree free rotation, which not only results in safer blade replacement, but at the same time also prolongs the service life of the transmission and structural components.Type: GrantFiled: June 4, 2003Date of Patent: December 14, 2004Inventors: Chien-Tsai Huang, Chun-Hsiang Huang
