Abstract: ABSTRACT OF THE DISCLOSURE          This invention relates to an improvement in a video disc playback system which derives video signals from a track on a video disc using a light source and an optical path to a lens system which is supported by an air bearing at a pre-determined spacing from the surface of the disc.  In the prior art, it has been extremely difficult to maintain an exact spac-ing between a read head and a video disc, and the variations in such spacing result in the reading beam going in and out of focus, producing a poor quality picture.  The present invention maintains constant spacing between the read head and the video disc by providing a read head which is yieldably mounted on a head support and adapted to be maintained in close proximity to the video disc surface.  A fluid bearing support member is coupled to the read head and has a surface adapted to create a fluid hearing between the fluid bearing support member and the rotating video disc.  An adjustable bias assembly, responsive to the radial position of the read head, applies a varying force to the read head in the direction of the disc to achieve the desired predetermined spacing between the head and the disc substantially independent of radial position of the head.

Abstract: ABSTRACT OF THE DISCLOSURE       Iron powder of high compressibility and low bulk density is made by atomizing a stream of molten steel by means of a conical jet of water from a nozzle downstream of a nozzle chamber at a rate in excess of 10 cubic meters water per metric ton of steel, the half cone angle is between 40° and 60°, preferably 45°; and air suction is provided in a region upstream from the cone, adjacent to the stream at a pressure of 0.02 to 0.20 bars below ambient, by means of a length adjustable tube extending down from the nozzle chamber.  The powder is reduced at 1,000°C to 1,200°C, and the resulting cake is broken up to obtain a powder having a particle size distribution with a higher content of larger particles than the powder immediately resulting from the atomization.  The iron powder combines high compressibility with high green strength of an article formed there-from by pressing of the powder.

Abstract: ISOTROPIC NONPLANAR RING LASER              ABSTRACT OF THE DISCLOSURE          A nonplanar ring laser for use as a laser gyro includes an even number of at least six reflecting surfaces which are preferably all made from the same coating batch or coating run so that they have substantially the same anisotropy charcteristics.  The mirrors are divided into pairs of mirrors, and the mirrors in at least each pair must match in their anisotropic characteristics.  Note that the matched mirrors need only be in the laser path but not necessarily adjacent.  The nonplanar geometric arrangment of the reflecting surfaces is such that the reflecting plane of incidence of each mirror is at substantially a right angle to the reflecting plane of incidence of at least one of the adjacent mirrors in the laser path.  Note that the reflecting plane of incidence of each mirror may optionally be at right angles to the reflecting planes of incidence of both its adjacent mirrors in the laser path.  The angles of incidence of the mirrors in each matched pair must be substantially the same.  Using this geometry, and at least the mirrors in each matched pair being from a single coating batch having the same anisotropy characteristics, the phase and attenuation shifts which are introduced by imperfect coatings are cancelled in the ring laser cavity.  Due to the substantial reduction in phase and attenuation anisotropy this ring laser configuration reduces coupling between the two modes travelling in the same direction when used in a multioschillator laser gyro, and therefore improves gyro performance.

Abstract: MAGNETIC CORE WITH MAGNETIC RIBBON IN GAP THEREOF    Abstract of the Disclosure A ferrite toroid has two radially extending gaps.  Into each gap there is inserted a magnetic metal ribbon folded over an insulative shim.  When current is applied to a winding on the core, the resultant magnetic flux is steered into the magnetic ribbons and around the gaps.  For high frequency excitations, eddy current losses in the ribbons are high and the windings have low Q, but high inductance.   At high winding currents, the magnetic ribbons are saturated, the inductance is reduced, and the Q of the winding increases.  In a switching voltage regulator, this inductor tends to generate only a small amount of ringing and electromagnetic radiation noise.
