Abstract: The present invention relates to a drill tool for rotary and/or percussive drilling comprising a drill head (10;10˝) including a pilot means (11;11˝) and a reamer means (12;12˝) located behind the pilot means (11;11˝) seen in the feed direction of the tool, guide means (16;16′;16˝;16‴) to guide said drill tool relative to a casing tube (15;15′) surrounding said guide means (16;16′;16˝;16‴), and cooperating driving means (18,19) on the guide means (16;16′;16˝;16‴) and the casing tube (15;15′), respectively, for downwards axial displacement of the casing tube (15;15′), and means for connecting said drill tool to a hammer drilling equipment. The invention also relates to a casing tube and a guide means per se. 
     When drilling through an overburden by a drill tool of the type specified above it quite often happens that the casing tube get stuck by wedge action from loose rock segments or by a sucking action, especially when the overburden consists of clay. 
     The present invention is characterized in that the casing tube (15;15′) is rotated by cooperating driving means on the guide means (16;16′;16˝;16‴) and the casing tube (15;15′).

Abstract: An adjustable, elastic wristband for dissipating the buildup of excess electrostatic discharge from an individual. The wristband has two straps or strap sections (18,20), one (18) electrically insulative and the other electrically (20) conductive, and at least one of the two straps or strap sections being elastic. A connector case (14) provides the electrical connection between the conductive strap (20) and a conductive grounding tether. Various clasps (16) are used to adjust the insulative strap (18) or strap section. In each of the disclosed alternative embodiments, the wristband may be adjusted for comfort without requiring trimming of the excess strap material which is pulled through the clasp (16), and without otherwise exposing any conductive portions of the wristband, since the excess adjusted material is electrically insulative and thus may be left dangling.

Abstract: The present invention pertains to a thin film magnetic recording head which minimizes erase fringing and the process for manufacturing the thin film magnetic recording head. The head is used to record and read information made up of alternating magnetization patterns on a magnetic recording medium. Known recording heads cause erase fringing of the magnetic medium during the write operations. The structure of the recording head of the present invention has the ABS portion of one of two magnetic poles beveled away from ABS at the gap to zero throat, reduces erase fringing of the magnetic recording medium and is easily manufactured. By reducing erase fringing, the present invention enables an increase in disk density of information without risking loss of data integrity.

Abstract: An algorithm for classifying cardiac arrhythmias comprising multiple stages and dual chamber sensing. A first stage includes the steps of comparing ventricular and atrial rates and declaring that the heart is in atrial tachycardia or atrial fibrillation on the one hand, or that the heart is in ventricular fibrillation on the other hand. The second stage is entered if no determination is made in the first stage and, in particular, when the atrial rate equals the ventricular rate. A third stage is entered in which the heart is paced (ventricular, atrial or both) at a predetermined rate for a set period of time. Cardiac rhythm classification is made based on heart responses during and after pacing.
