Title: Method of detecting cracks in constructions
Inventor: HELLQVIST KJELL A
IPC: G01S5/18
Filed: 1981-08-24
Granted: 1984-11-27
Abstract: ABSTRACT The invention relates to the monitoring of the presence of cracks, formation of cracks and growth of cracks in constructions, preferably complex steel con-structions, for example off-shore platforms.  The crack indication is brought about by recording and analysis of acoustic emission from a crack in the construction and the invention is characterized in that a plurality of sensors, for example microphones or hydro-phones, are mounted in the medium which surrounds the construction and record acoustic emissions from a crack to the medium which surrounds the construction. The sig-nals measured by means of the sensors are fed to a signal analysis system in a computor which renders it possible to determine the position of the emission source, that is to say the crack, by analysis of the sensor signals caused by acoustic emission.

Abstract: ABSTRACT OF THE DISCLOSURE A single ended hydraulic actuator requiring hydraulic pressure to extend the piston for raising the cowl door of a jet engine and the like. A preload spring device carried in the piston-rod assembly produces an extend force when the actuator is retracted and the door is closed which preloads the actuator to help eliminate fretting of the bearings and piston rod which otherwise can occur due to flight vibrations when unloaded.

Abstract: Abstract Method and Apparatus for Reducing Electrolyte Loss from an Electrochemical Cell In an electrochemical cell wherein during operation electrolyte evaporates into a reactant gas stream, the evaporated electrolyte, before it leaves the cell as a vapor in the reactant gas exhaust stream, is condensed from the gas stream by reducing the temperature of the reactant gas stream just before it exits the cell.  The condensed electrolyte is taken up by the cell electrode and redistributed throughout the cell by diffusion and capillary action.

Abstract: Abstract of the Disclosure An orthopedic surgical instrument for arthroscopic arthroplasty of the joints of the body, adapted for insertion into the joint through a puncture wound and capable of removing degenerated cartilage and bone over an extended surface area, to a limited depth, to expose blood supply to induce growth of fibrous secondary cartilage to regenerate an articular surface.  The instrument is a rotating, semi-shielded cartilage and bone abrading, suctioning instrument featuring an outer tubular sheath attached to a support and within the sheath, an inner tubular shaft; at the distal end of the inner tubular shaft, partially shielded by the outer sheath, is an abrading element that is rotated to present an abrading surface.  At its proximal end, the inner tubular shaft is connected to a vacuum source for removal of tissue-carrying fluid and bone abraded from the joint surface.  This fluid reaches the tubular shaft from the region of the abrading element via an inlet and a passage through an annular distal bearing which supports the inner tubular shaft, the shaft being subject to transverse loading during bone-abrading engagement.  Powered means are provided to rotate the inner tubular shaft relative to the outer sheath under bone-abrading load.

Abstract: Abstract of the disclosure:     According to the continuous process according to the invention for digesting cellulose-containing material (substrate) with gaseous hydrogen fluoride, HF is sorbed by the substrate at a temperature above its boiling point in n sorption steps and thereafter the sorbed HF is removed from the substrate by heating in n desorption steps.  The number n of sorption steps and of desorption steps is identical and the reaction steps mentioned each occur in reactors which are separated from one another in a gas-tight manner.  After introduction into the first sorption reactor (1a), the substrate passes consecutively through gas-tight valves into the second (1b) ...nth sorp-tion reactor and from the latter, optionally via a hold-up reactor (2) into the first, second, ... nth desorption reactor (3a) and is removed from the nth desorption reac-tor (3a).

Abstract: ABSTRACT      A magnetic gas gate adapted to operatively connect two adjacent dedicated chambers, in the first chamber of which a first layer is deposited upon a magnetic web of substrate material and in the second chamber of which a second layer is deposited onto the first layer.  The first chamber has introduced thereinto gas constituents used to form the first layer while the second chamber (1) has introduced thereinto gas constituents used to form the second layer which constituents include at least one gas not introduced into the first chamber; and (2) is operatively associated with a mechanism for unidirectionally drawing the gases from the first chamber side of the gas gate toward the second chamber side of the gas gate.  It is important that the second chamber gas constituents be substantially prevented from backflowing or diffusing through the gas gate to contaminate the gas constituents in the first chamber,  To prevent contamination of the first chamber constituents from the second chamber gas constituents, the present invention substantially reduces the size of the passageway through the gas gate by creating a magnetic field adapted to urge the unlayered surface of the magnetic substrate into sliding contact with one of the walls of the passageway.          Since the size of the gas gate passageway is re-duced, the backflow of gas constituents from the second chamber is correspondingly reduced, thereby providing for the production of a more efficient product.  The magnetic gas gate of the present invention provides the additional benefit of re-ducing warpage of the magnetic web of substrate material which also results in the production of a more efficient product.
