Abstract: ABSTRACT            LONGITUDINAL MODE STABILIZED LASER Stabilised, single-mode operation of semiconductor lasers is obtained by introducing longitudinally spaced variations in the effective refractive index along the active waveguiding medium (12) by means of variations (10-1 to 10-m) in the thickness of one of the cladding layers (11).  These index changes have a spatial period corresponding to many half-wavelengths of the guided optic wave.  Because the spatial period of the variations is relatively long, as opposed to half an optical wavelength used in the propr art distributed feedback lasers, a Laser in accordance with the invention is much easier to fabricate.

Abstract: ABSTRACT:          Method of monitoring a radio link between a base station and a mobile station.     In radio transmission systems which are known the monitoring of a radio link between a base station and a mobile station is effected by means of an evaluation of the received field strength or of the sig-nal-to-noise ratio. This evaluation is not reliable in the case of a radio transmission system with a high number of transmission channels or in the case of radio zones which overlap to a considerable extent.         Radio messages are registered and evaluated in the base sta-tion in order to monitor an existing radio link.

Abstract: NHL-KFJ-02 Canada AN IMPROVED NICKEL OXIDE BASED DIAPHRAGM                     ABSTRACT OF THE DISCLOSURE    The invention concerns a NiO-based ceramic oxide diaphragm for the alkaline water electrolysis.  The diaphragm, in accordance with the invention, contains 0.5 to 10% by weight estimated as Ti based on the oxide mass of titanium oxide in the porous NiO layer.  Diaphragms of this type are obtained, in particular, by the oxidative sintering of a mass of nickel powder which has been applied under pressure to a nickel support, especially one consisting of nickel wire gauze.  In the process the titanium is in the form of titanium metal, titanium oxide or a titanium compound which is added to the initial nickel powder.          The titanium is present in the form of its oxide after the oxidation sintering treatment.  In an alternative embodiment of the process,  an already sintered porous mass of nickel or nickel oxide can be impregnated with a titanium compound and calcined to convert the titanium compound to its oxide.

Abstract: "MATERIAL HANDLING DEVICE" ABSTRACT OF THE DISCLOSURE               The device is operative to discharge the triangular ridge of grain, which remains in the bottom of a cylindrical storage bin after the bulk of the bin contents has been discharged by gravity through a central outlet in the bin floor.  The device comprises a vertical, rotatable driven shaft mounted to extend upwardly from the outlet.  A free-floating sweep arm is pivotally attached at its inner end to the base of the shaft, so that said arm can rise or fall in a vertical plane.  The sweep arm extends outwardly to the wall of the bin.  A plurality of parallel, spaced apart, stationary fins protrude downwardly from the undersurface of the sweep arm.  The fins are arranged at a trailing angle of about 45°, relative to the longitudinal axis of the sweep arm.  The forward end of each fin is located on a radius which is equal to or larger than the radius on which the rear end of the next outer fin is located.  Thus grain moved inwardly by the outer fin is contacted by the inner fin.  The fins progressively increase in depth from the outer end of the sweep arm to its inner end, so that each fin is adapted to move about the same volume of grain,even though each fin moves at a different velocity when the arm is sweeping. In operation, the fins penetrate by gravity into the grain.          The free-floating arm is adapted to constantly conform with the surface of the grain body.  The fins thus consistently move a constant volume of the grain inwardly, for discharge through the central outlet.

Abstract: ABSTRACT           The invention is concerned with an absorbent body of fibrous material for absorbing body fluids. The body being generally planar and elongated and having a substantially uniformly compressed peripheral edge extending about essentially the entire periphery of the body.  The peripheral edge has a density of at least ten times greater than the least dense portion of the body, the dense peripheral edge extending inwardly from the extreme periphery for a distance of at least 0.1 cm.  The body is provided with a longitudinal density gradient.  The longitudinal gradient extending from a point of least density longitudinally toward the compressed peripheral edge with the density increasing toward the peripheral edge at an increasing rate.  The body is also provided with a transverse density gradient, the transverse gradient extending from a point of least density transversely toward the compressed peripheral edge and the transverse density increasing toward the peripheral edge at an increasing rate.  Thus, body fluid striking the body at a point in proximity to the peripheral edge will be transported rapidly away from that point.

Abstract: ABSTRACT      A device for sorting fish into uniform head-tail alignment is characterized by a truncated conic disc driven rotatingly about a horizontal axis, which disc, with its corundum-coated smaller frontal surface in connection with a gripping surface fixed to the frame of the device and opposing the frontal surface in the region above the axis, forms a gripping gap into which fish supplied with their tail end leading are introduced with their tailfins.  Due to the rotation of the truncated conic disc the tail part of the fish is entrained by frictional engagement.          During that process the fish is gradually placed on its tail so that a shift into the head-first position occurs, in which position the fish is set free at the end of the gripping surface.

Abstract: ABSTRACT OF THE DISCLOSURE         In a system for recording and reproducing digital signals on a magnetic tape by using a rotary head, in which signals are recorded as a series of slanted tracks without guard bands, a pilot signal that controls tracking alignment of a playback head is recorded at a particular position in a specific pilot signal record region, independent from the information signal record region.  The pilot signal is arranged at first predetermined positions separated from the ends of the slanted tracks in the pilot signal record region on every other one of the slanted tracks and at second predetermined positions separated from the ends of the slanted tracks in the pilot signal record region on the alternate ones of the slanted tracks.  An erase signal can also be recorded in the pilot signal record region  such that a start position of the erase signal corresponds substantially to a center portion of the pilot signal on the adjacent track.  When the recorded tracks are reproduced by a rotary playback head having a tracing width greater than the track width, the pilot signals from the adjacent tracks will be detected and compared in level, and the comparison output used to control the tracking alignment of the rotary playback head.

Abstract: ABSTRACT OF THE DISCLOSURE      The vane slot 20 and lubricating oil passageway 21 in the cylinder member 3 of a rotary vane compressor are configured such that the radial length of the slot wall 20a on the low pressure side of the vane 5 is less than that of the opposite wall 20b on the high pressure side.  Such a shortened low pressure side slot wall reduces wear by providing improved lubrication at the critical inward edge of the slot (FI), and facilitates the flushing away of abrasive particles formed during the initial seating of the vane.  For a horizontal installation the lubricating oil level is maintained below the radially outermost edge of the wall 20a to prevent the oil from being drawn into the low pressure chamber 17 when the compressor is stopped.
