Abstract: METHOD FOR RECORDING INFORMATION     SIGNAL AND CONTROL SIGNAL               ABSTRACT OF THE DISCLOSURE    A first main information signal is recorded in a first track extending longitudinally along one side of a length of magnetic tape and a corresponding first secondary, or control, signal is recorded in a narrow parallel track spaced from the first main track.  A second main signal is recorded in a third track within the other half of the tape, and a corresponding second secondary, or control, signal is re-corded between the first secondary signal and the first main signal, whereby the two main signals and the two secondary signals are interleaved with each other.  The first and second main tracks are equal in width, and the first and second secondary tracks are also equal in width but are much narrower than the first and second main tracks.  If desired, the first and second main tracks can each be divided into first and second sub-main tracks to permit two channel record-ing with a control track in each direction but with each con-trol, or secondary, track being separated from its own nearest subtrack by a distance equal to the width of the other second-ary track plus two guardbands, one on each side of the other secondary track.

Abstract: ABSTRACT OF THE DISCLOSURE           This disclosure relates to a segmented retainer for rollers of a roller bearing.  The retainer includes a pair of end rings having circumferentially spaced separator bars extending therebetween.  The separator bars are fixedly secured to the end rings against displacement and rotation.          Each separator bar has a configuration wherein at each side thereof there are two radially spaced bearing surfaces separated by a lubricant pocket.  The convex shape of the bearing surfaces, in conjunction with the convex rolling surfaces of associated rollers provide for suitable lubricant pockets and lubricant flow thereby providing adequate lubri-cation between the roller and the separator bars.  The bars are secured to the end rings by a plurality of different means including welding and interfitting mechanical inter-locks.  Primarily, each bar is provided at each end thereof with a projection which is of a stepped configuration wherein the interlock between each bar and each side ring is of a greater than normal radial extent thereby preventing twisting or rotation of the bar with respect to its associated side rings.

Abstract: ABSTRACT OF THE DISCLOSURE    Disclosed is a piston ring including a spacer-expander spring member.  In a preferred embodiment the ring is of cast iron and includes two axially spaced cylinder wall contacting lands. At least one generally rectangular inwardly facing spring receiving recess is formed in the interior wall of the ring to receive the spring member which is formed from a flat strip of metal in a "U" configuration with the legs thereof facing outwardly, preferably aligned with the lands on the ring.  A plurality of slots are pro-vided in the spring member dividing the periphery into a plurality of feet.  In a preferred embodiment the feet are radiused as seen in plan view to a radius less than the radius of the pocket in which they fit.  This has been found to reduce wear in the spring receiving groove and to reduce the tendency of the ring and spring to become united which is detrimental to performance and is a common problem in rings of this general type.

Abstract: PNEUMATIC CONTROL OF THE MOTION        OF OBJECTS SUSPENDED ON AN AIR FILM                     ABSTRACT    This specification deals with the stopping, posi-tioning,orienting and redirecting a semiconductor wafer being transported along a track on an air film or bed of air.  The stopping mechanism is an air jet located in a groove in the track, wafers passing over this air jet on an air film are sensed by a pneumatic sensor that turns on the air jet to set up an air stream under the transporting surface of the air film.  This air stream sucks the fluid in the air film along with it in the groove causing a vacuum in the bed in the area of the noz-zle of the air jet.  The wafers are then stopped by the suction of the vacuum.    Positioning, orienting and redirecting is done using the air jet and pneumatic sensor in combination with special air jet arrangements and operations.

Abstract: ABSTRACT OF THE DISCLOSURE           Closed loop propagation channels for magnetic bubbles are mutually exclusively accessed by means of two different sets of repeating sequences of discrete, pulsed magnetic drive field orientations.   A closed loop bubble propagation circuit is driven by a repeating sequence of pulsed orientations in which a plurality of interlaced subsets of the sequence operate corres-ponding sections of the circuit.   A closed loop zigzag circuit traversing sections of the loop parallel to the sides of an equilateral triangle is driven by a sequence of pulsed field orientations aligned respectively with the sides of the equilateral triangle.   Continuous overlay circuits are introduced driven by sequences of discrete nonorthogonal, pulsed drive field orienta-tions repetitively realigning with consecutive segments of the overlay circuit.

Abstract: ABSTRACT OF THE DISCLOSURE      An improved pressed glass lens member for a sealed beam lamp unit is provided to include an outer sealing rim of varying thickness to compensate for thermal contraction of the lens member when molded in a predetermined manner. Specifically, the ordinary warped condition encountered with thermal contraction of the pressed glass article when initially formed is compensated for so as to permit subsequent heat sealing with a pressed glass reflector member by thermally fusing the glass material of both members in the sealing regions and without encountering the manufacturing defects now being experienced. The preferred embodiments illustrate such controlled thickness variation of the body section in the outer sealing rim region of a pressed glass lens member for both circular-shaped and rectangular-shaped lens con-figurations. Additionally, the rectangular-shaped pressed glass lens member embodiment illustrated can further include a molded projection provided on the back sealing surface of the rim region to further reduce unwanted deformation which otherwise occurs when the lens member is initially formed by pressing in glass molds.

Abstract: Abstract of the Disclosure A method for reacting pulverized coal with heated hydrogen-rich gas to form hydrocarbon liquids suitable for conversion to fuels wherein the reaction in-volves injection of pulverized coal entrained in a minimum amount of gas and mixing the entrained coal at ambient temperature with a separate source of heated hydrogen.  In accordance with the present invention, the hydrogen is heated by reacting a small portion of the hydrogen-rich gas with oxygen in a first reaction zone to form a gas stream having a temperature in excess of about 1000°C and comprising a major amount of hydrogen and a minor amount of water vapor.  The coal particles then are reacted with the hydrogen in a second reaction zone downstream of the first reaction zone.  The products of reaction may be rapidly quenched as they exit the second reaction zone and are subsequently collected.
