Abstract: GYROSCOPIC APPARATUS              ABSTRACT OF THE DISCLOSURE            A gyrocompass has a gimbal (18;218) rotatable about an upright axis (22;222) and a gyro (10;210) ro-tatably mounted in this gimbal (18;218) about an inner axis (16;216) transverse to the upright axis (22;222). The gyrocompass also includes a level sensor (30,32;230, 232) supported by the gimbal (18;218) for providing a level signal signifying the tilt of the upright axis (22;222) from vertical.  Also included is a controller (50) connected to the level sensor (30,32;230,232).  The controller includes equipment (50) responsive to the level signal for rotating the gimbal (18;218) into an initial position (SP(l)) at which the level signal has a predetermined value.  A method employing the fore-going apparatus includes the steps of rotating the gimbal (18;218) until the level sensor (30,32;230,232) indicates the inner axis (16;216) is horizontal.  Another step is measuring the torque applied to the gyroscope (10;210) by the horizontal component of rotation of the earth with the spin axis (SAl;SA) of the gyroscope (10;210) rotated about the inner axis (16;216) into a horizontal position.  Other steps are rotating the gimbal (18;218) 180 degrees and remeasuring the torque applied to the gyroscope (10;210) by the horizontal component of rotation of the earth with the spin axis (SAl;SA) of the gyroscope (10;210) rotated about the inner axis (16;216) into a horizontal position.

Abstract: HIGH POWER CESIUM LAMP SYSTEM FOR LASER PUMPING           Abstract of the Disclosure A long-life cesium lamp is disposed within an evac-uable outer envelope surrounding a cesium lamp arc tube with their respective surfaces spaced a fixed distance apart so that a heat-transferring gas, such as helium, is disposed between the arc tube and the wall or the outer envelope.  Fur-thermore, means are provided for cooling the outer envelope, such as by surrounding it with a water jacket.  The resulting lamp system is capable of operating at higher levels of average lamp power and arc tube wall loading (watts/cm2) without caus-ing too low a cesium pressure, as would happen if one directly water-cooled the alumina arc tube, and without causing too high an alumina arc tube temperature, as would happen if one merely evacuated the outer envelope.  The lamp system of the present invention is also employed in a housing in which the lamps are disposed along the foci or a dual-elliptical cavity so that light emissions from the lamps are focussed upon a slab of lasing material, so as to form, for example, a neodymium-YAG laser.

Abstract: ABSTRACT OF THE INVENTION    A cursor control device having particular application to a computer  display system  is disclosed. The cursor  control includes a unitary framer having a domed portion substantially surrounding and retaining a ball which is free to rotate.  X-Y position indicating means are provided, such that rotation of the ball provides signals indicative of X-Y positions on the display system.  The ball is free to "float" in the vertical direction within the dome, and thereby maintain good surface contact.  X-Y positions are established by movement of the control device over a surface.  A display system and method is disclosed for use in conjunction with the cursor control device, which permits a user to select command options simply by movement of the displayed cursor over a "pull-down" menu bar.

Abstract: ABSTRACT OF THE DISCLOSURE           A moderator having a high modulus of elasticity is disclosed for use in an article of footwear having an upper and at least a sole secured to said upper and including a cushioning material located between the sole wearer's foot.  The moderator is made of a relatively thin, light weight material having a modulus of elasticity of at least about 250,000 p.s.i.  The moderator has the ability to deflect without permanent deformation in response to an applied load creating a deflecting stress within the member and will return to its original shape upon removal of the applied load.  The deflection of the member permits absorption, redistribution and storage of the energy of localized loads applied thereto and returns the energy to the wearer at a rate equal to or greater than the rate at which the applied load is removed. This results in improved comfort, support and stability for the foot and lower leg.

Abstract: ABSTRACT           METHOD AND APPARATUS FOR REMOVING  DRAWN CONTAINER FROM DRAW HORN    Apparatus for removing a drawn container from a draw horn which is carried by the inner slide of a double acting press includes a stripper assembly also carried by the inner slide and capable of controlled axial movement relatively of the draw horn.  The draw horn and draw riser have coaxial, centrally disposed bores within which is received an elon-gate shaft of the stripper assembly.  The distal end of the shaft carries a stripper pad while the proximal end  is adjustably connected to a pivoting linkage mounted on the inner slide and normally pivoted under pressure by a pneu-matically actuated piston so as to maintain the stripper assembly in retracted condition, the pad then forming the bottom of the horn.  The method includes timing the press so that, upon movement of the inner and outer slides away from the bottom platen of the press, the inner slide trails the outer slide by a predetermined amount so that the outer slide  comes  into contact with  one  end of  the  pivoting linkage of  the  stripper  assembly thereby overcoming  the piston and enabling the stripper pad to be disposed in an axially extended position with respect to the draw horn.  As the inner and outer slides continue to move away from the lower platen, the stripper pad, which is in contact with the bottom of the drawn container, effectively holds the con-tainer while the horn is pulled out of it.  Final removal may be assisted by air pressure.
