Abstract: APPLICANTS:  SVENSKA TRAFORSKNINGSINSTITUTET          TITLE: METHOD FOR SAWING A LOG OR A BLOCK INTO PIECES OF LUMBER     ABSTRACT OF THE DISCLOSURE            The present invention relates to a process for sawing a log or a block into pieces of lumber, such as blocks, planks, boards, etc. The method is characterized in that pieces of lumber are sawn out with longitudinal cut surfaces such that - when the log is viewed in cross section - the lateral surface of the piece of lumber facing the center of the log is substantially concave while its lateral surface facing away from the center of the log is substantially convex, the concavity and convexity being adapted to the local tangential and radial shrinkage properties of the wood so that the sawn pieces, after drying to the desired moisture ratio, will have substantially plane-parallel sides.

Abstract: Abstract of the Disclosure A lathe for cutting a spiral strip of veneer from the surface of a log includes motor driven mechanisms for adjusting the knife blade pitch angle and edge height, and for moving a pressure head relative to the knife to adjust the vertical gap and horizontal gap between the knife edge and the roller bar, and provides sensors for determining the actual positions of movable elements of the lathe, thus enabling computer-controlled adjustment of the movable elements of the lathe during lathe operation.       A knife clamp of the lathe includes a plurality of separate clamp segments for pressing against different portions of a knife bar to hold it firmly, resisting deformation and rocking of the knife bar.  Fluid-pressure-biased bearings eliminate looseness between relatively movable parts of the lathe, reducing the amount of variation of thickness in veneer produced using the lathe.  Veneer thickness is controlled by monitoring cumulative movement of the lathe spindles and the main feed carriage.

Abstract: ABSTRACT           A squelch circuit in which a phase locked loop (PLL) 5 having a voltage controlled oscillator (VCO) 7 and a phase comparator 10 is used to detect the number of zero crossings, these being low for a speech signal and high for noise.   The error voltage produced in the phase locked loop 5 is fed through a network 12 which ensures that the matching of the input signal to the oscillator is faster when the input frequency drops than when the input frequency rises.   The input signal is clipped to enhance the freq-uency spectra of speech by using a limiting amplifier.  The muting gate 2 output is derived from the VCO 7 control volt-age of the PLL 5 to mute the output of the receiver when the VCO 7 output frequency is higher than a preset frequency for more than a preset time.

Abstract: ABSTRACT            RAPID CLOSING MECHANISM OF A MINIATURE CIRCUIT BREAKER            Rapid manual closing of a miniature circuit breaker with a pivoting operating handle (10) is brought about by the presence of a flexible strip (56) engaged by a protruber-ance (54) on the handle (10) in the course of the pivoting movement of the latter. The deformation of the flexible strip (56) imposes an increased effort to operate the han-dle and, once the deformed flexible strip (56) has been overrun, this increased effort is available for a rapid movement with contact spring (42) loading to closed pos-ition of the contacts (38, 40). A manual opening operation by pivoting the handle (10) in the opposite direction takes place normally, the flexible strip (56) withdrawing by sim-ple pivoting from the trajectory of the protruberance (54).            Refer to figure 1.

Abstract: ABSTRACT          A protective device is disclosed for a platform installed in the open sea.  The device protects the platform against the impact of floating objects such as icebergs or ships.  A protective body surrounds the platform to be protected and has a bottom with inclined bearing surfaces. This body is movably supported on large bearings having inclined bearing areas that engage slidingly the bearing surfaces.  A foundation supports the bearings which preferably are mounted for rotation on the foundation.  When the device is struck by a floating object the kinetic energy of the impact pushes the protective body upwards on a portion of the inclined bearing areas and is transformed into potential energy of the elevated body.  The protective body is able to slide back to its initial position after impact using its received potential energy to thrust away the floating object from the endangered platform.

Abstract: METHOD OF MAKING AN INTRAMEDULLARY BONE PLUG AND BONE PLUG                MADE THEREBY                       ABSTRACT           This invention relates to a method of making an inflatable bone plug for plugging the open end of an intramedullary bone canal which is capable of restricting the flow of bone cement, particularly, during the insertion of bone cement, particularly during the pressurized injection of such a cement, during an operative procedure involving the fixation of the stem of an artificial joint prosthesis such as a femoral hip joint prosthesis to the end of a bone such as a femur.  The bone plug is designed to be pressurized with a biocompatible fluid and to thereafter deflate in a controlled manner after the cement hardens. Preferably, the bone plug is made by forming a hollow expandable container of a silicone elastomer permeable to carbon dioxide gas which has a valve stem attached to one end of the container and an opening at the opposite end of the container.  A shrinkable elastomeric band is placed over the valve stem in which a channel has been made to receive a further cooperating injection means such as a needle.  The elastomeric band shrinks over the valve stem to form a resealable valve assembly.  The valve assembly is located in the hollow interior of the bone plug and the opening opposite the valve stem is sealed to complete construction of the bone plug.  When such a plug is inflated with a biocompatible fluid such as carbon dioxide, the plug remains pressurized for a sufficient amount of time to allow the cement to harden, but the pressure drops to a minimum within about 24 hours after inflation.
