Abstract: TITLE OF THE INVENTION          IMPROVED MANDREL HAVING AN EDDY CURRENT PROBE            ABSTRACT OF THE DISCLOSURE    An improved fluid mandrel having an eddy current probe connected thereto is disclosed herein. The eddy current probe generally comprises a probe body which is detachably connectable to the bottom of a fluid mandrel on one end, and a source of hydraulic fluid on the other end. The probe body includes a pair of sensing coils which are separated along the longitudinal axis of the body by a distance approximately equal to the thickness of the metallic structure desired to be detected. The improved mandrel finds particular application in performing expansions which eliminate the clearance between heat exchange tubes extending through the baffle plates in nuclear steam generators. In such an application, the sensing coils of the probe are longitudinally spaced the same distance as the thickness of the baffle plates in order to generate a sharp and unambiguous electronic signal indicative of the relative positions of the mandrel and the baffle plate.

Abstract: ABSTRACT                 A SEALED FLUID SWIVEL JOINT        A seal arrangement for a fluid swivel joint such, as is commonly used on offshore loading terminals for tankers, includes first and second adjacent joint rings 30, 32 which are rotatable relative to each other about a common central longitudinal axis. The joint rings 30, 32 have a small annular clearance gap 34 therebetween to allow relative rotational movement, and one of the rings includes an annular seal housing groove 42 communicating with the clearance gap 34.  An annular seal is positioned in the seal housing groove 42, and includes a pliant annular, sealing member 44 and an adjacent free-floating anti-extrusion ring 46 to prevent the pliant sealing member 44 from being deformed into the clearance gap by a relatively high fluid pressure differential existing across the seal.  An oil injection system circulates a flow of oil between a sealing face on one of the joint rings 30 and the contacting surfaces of the sealing member 44 and anti-extrusion 46 so as to remove generated heat and any seal wear debris from the seal arrangement.

Abstract: ABSTRACT OF THE INVENTION/      A connector element (62) to provide a releasable connection between two framing components, in particular a support and a casing profile, the connector element (62) being arranged and fixed within the casing that is configured as a hollow profile, and having at least one lock element (64) in a housing (63), with which the connector (62) and thus also the casing can be releasably connected with the support, and in which connection an eccentric is mounted in the  housing (63) of the connector (62) so as to be rotatable, by means of which the lock element (64) can he moved longitudinally within the housing (63), whereby a component (70) of the lock element (64) that projects from the face side of the housing (63) can be introduced into an undercut groove in the support and there clamped, and in which  the eccentric head (76) of the eccentric (75) that can be pushed into the housing (63) can snap into a drilled hole in the casing, this connector being so developed that by using it it is possible to achieve a heavily loadable, releasable connection for two framing components, in which regard the connectors are to be of the same size as already known connectors and simple to assemble.  This has been achieved in that the component (64,70) of the lock element, which projects from the housing (63) is rotatable through a limited angular range about its longitudinal axis, in the the lock element (64) is movably connected through a tension element (74) with the eccentric (75) and in that the free end of the projecting component (64) terminates in a cross bolt (70).

Abstract: ABSTRACT OF THE DISCLOSURE:           A method and an equipment for the detection of a mechanical abnormality or injury in the lumbar spine of a patient and for the identification of this abnormality or injury as being of the compression or torsion type.  In a first step, any variation of the lumbar curve of the patient is measured using a combined visual and an electromyographic (EMG) technique.  Then, any discrepancy or assymetry is detected in said measured variation of lumbar curve.  In practice, the absence of any variation or the detection of any discrepancy or assymetry in the case where a variation is measured, is indicative of the presence of a mechanical abnormality or injury of the lumbar spine of the patient, and of the nature of this particular abnormality or injury.

A front electrode comprises a tubular metal member having a bore therethrough, the front electrode being mounted within the housing and in coaxial alignment with the rear electrode and having an inner end adjacent the open outer end of the rear electrode and an opposite outer end.  Vortex generating means is provided for generating a vortical flow of a gas at a location intermediate the rear and front electrodes and which is in coaxial alignment with the rear and front electrodes.  A power supply means is operatively connected to the rear and front electrodes for generating an arc which is adapted to extend axially from the rear electrode through the vortical flow of gas and to an attachment point located on the front electrode.  The improvement pertains to the bore of the front electrode including an outer end portion which is cup-shaped in cross section to define an outwardly facing radial shoulder, and wherein the power supply means includes a direct current source with the anode thereof connected to the rear electrode and the cathode thereof connected to the front electrode. Means is provided for coordinating the vortex generating means and the power supply means such that the arc attaches on the radial shoulder of the front electrode, and whereby the attachment of the arc to the radial shoulder results in erosion of the material of the front electrode along an axial path of travel rather than radially through the electrode, to thereby extend the life of the front electrode.

Abstract: MAGNETIC HEAD POSITIONING APPARATUS AND METHOD Abstract of the Disclosure An apparatus and method are disclosed for positioning magnetic heads relative to the recording tracks of a recording medium such as a floppy disk having circular, concentric recording tracks formed thereon.  The magnetic heads are mounted on a head carriage, and the head carriage is moved, in response to received command pulses, so that the heads are moved linearly, by step increments, along a radius of the floppy disk.  The heads are thereby moved across the spaced tracks on the disk, with each incremental movement of the heads being a distance less than the distance between the tracks, and being, for example, one-half or one-fourth of the total distance between tracks. Acoustic noise due to head movement is minimized by moving the heads by increments less than the distance between the tracks, with such movement avoiding exciting the resonances of the head moving apparatus.   The magnetic heads are initially moved at a rate known to avoid exciting the resonance and, during such initial movement, the rate of received command pulses is determined.  If the received command pulse rate is within a predetermined range, and is a rate that will not excite resonance, continued movement of the head is at the rate of the received command pulses.
