20110000306 | Method for detecting the stop of the yarn unwinding from a yarn feeder provided with a stationary drum - In order to detect the stop of the yarn unwinding from a yarn feeder provided with a stationary drum and with a sensor generating a pulse per each yarn loop unwound from the drum, a threshold time interval is continuously computed, which corresponds to the maximum interval between two successive pulses, above which it should be regarded that an accidental stop of the yarn has occurred. The threshold time interval is updated in real time as a function of the yarn-drawing speed. Then the delay from the last pulse is continuously measured and compared with the updated threshold time interval. The machine is stopped when the measured delay overcomes the updated threshold interval. | 01-06-2011 |
20110232393 | SEALED SENSOR WITH STRAIN GAUGES - A sealed sensor includes a test body configured as a deformable simple parallelogram, including a one-piece test body having a generally H- or X-shaped central opening extending therethrough, whose shape determines four hinge positions of the parallelogram, between the end of each arm of the opening and one face of the test body, and the thickness thereof. At least one hinge is a measuring hinge on one side of the test body. The outer face of the body has a recess and housing for strain gauges and circuits. At least one pair of side cavities define therebetween the width of the measuring hinge(s) and the thickness of the sheets of material connecting side edges of this measuring hinge to side edges of the test body corresponding to the hinge, preventing strains generated in the measuring hinges from being affected by strains from the side edges of the test body. | 09-29-2011 |
20120111122 | METHOD AND DEVICE FOR DETERMINING THE PROPERTIES OF A PRESSURE-MANIPULABLE TEST SAMPLE - A method for determining the plasto-elastic properties of a test sample, which can be affected by the action of pressure, includes pressing a test body against a surface of the test sample with a defined force. Plasto-elastic changes of the surface resulting therefrom are recorded during and/or after the pressure application. A centrifugal force generated by rotating the test body around an axis is utilized as a pressure force which is generated by radially movably guiding the test body, which is disposed between the test sample and the axis, relative to the radially fixed test sample. | 05-10-2012 |

20130283923 | DETERMINATION OF NEAR SURFACE GEOPHYSCIAL PROPERTIES BY IMPULSIVE DISPLACEMENT EVENTS - The invention is an improved technique for measuring near surface attributes of the ground while conducting a seismic survey. The improved technique is enabled by an electric vibe using a number of linear electric motors that direct a rod or piston to contact the ground in a recurring fashion. By applying constant force on the rods of the linear electric motors against the ground, the penetration into the ground may be measured for both rate and overall deformation. This information provides an accurate indication of viscosity and stiffness. In addition shear velocity and compression velocity may be measured and in some conditions, even the type of prominent shear wave may be identified for the area. | 10-31-2013 |
20140137659 | DUAL THRESHOLD SENSOR FOR DETECTING RELATIVE MOVEMENT - A sensor detects relative mechanical movement between two components. The sensor has two arms, and is to be mounted on one of the two components. Each of the arms has pins received in an opening in two fuse portions. The arms are pivotal within a fuse bracket. The two fuse portions include a thin portion to allow each to fracture. The fuse portions are designed to be distinct such that a distinct amount of relative movement between the first and second arms is allowed before each of the fuse portions fracture. | 05-22-2014 |
