Abstract: Abstract of the Disclosure An oil cooled diesel engine piston is designed to restrict heat loss from the combustion chamber through provision of a combustion chamber insert defining a central non-oil-cooled chamber and a surrounding annular insulating air gap.  The air gap controls heat flow primarily between the combustion gas exposed wall of the insert and an adjacent coolant exposed wall of the main piston volume.          The insert is press fitted into a recess in the main piston body and is positively locked therein by a retaining ring.  A seal ring closes expansion clearance provided at the upper edge of the insert against signifi-cant gas flow into the insulating air gap.  Insulating efficiency of the air gap is maximized by forming the gap with a thickness throughout a major portion of its extent of between about .040 and .060 inches.          Numerous additional features are also disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE     To the body of a feeding bottle, of the type in glass or other reusable material, or of the type in plastic or other disposable material, there is applied a valve for manual regulation, without interruption of feed-ing, of the quantity of air which must replace the escaped liquid as a function of the sub-pressure generated by the sucking.  The nipple has an area which is of lesser thickness than the rest and is therefore of a geometry that varies automatically with the sub-pressure present in the bottle so as to appraise the variation of this sub-pressure in the course of the sucking and to control the effects of said air valve.

Abstract: ABSTRACT OF THE DISCLOSURE Method and apparatus for recovering information at a substantially constant rate from a rotable information storage disc.  The information is stored on the disc in a plurality of substantially circular and concentrically arranged information tracks, with a substantially uniform recording density, and it is recovered by controllably rotating the disc, relative to a transducer, at an angular velocity substantially inversely proportional to the radius of the corresponding track.  The apparatus includes a coarse speed control potentiometer for producing a measure of the radius of the particular information track from which information is being recovered, and fine speed control means for comparing the relative phase angles of a periodic signal in the recovered information and a periodic reference signal and for producing a fine speed control signal proportional to the phase difference.  The measure of radius and the fine speed control signal are summed together and coupled to a voltage-controlled oscillator to produce a composite speed control signal, which is coupled to a servo to rotate the disc at a corresponding angular velocity.

Abstract: METHOD AND MEANS FOR DAMPING SUBSYNCHRONOUS OSCILLATIONS   AND DC OFFSET IN AN AC POWER SYSTEM            Abstract of the Disclosure Subsynchronous oscillations and DC offset in an electri-cal power system are dampened by measuring the half-cycle period of current or voltage line waves, comparing the measured half-cycle time periods to a desired half-cycle time period and dissipating the line waves in measured half-cycle time periods which are longer than the desired half-cycle time period.  Damping apparatus includes a reactance connected in a power line with selectively bi-directional conductors in parallel with the reactance whereby the reactance can be shorted.  Alternatively, the selectively bi-directional conductors can connect a power line to ground or neutral when half-cycle time periods exceed a desired half-cycle time period.

The character definitions and screen buffer for each picture to be displayed are constructed in a remote host central processing unit.  In order to minimise the time that a user has a blank screen the character definition and screen buffer data is sent from the c.p.u. to the display unit in groups relating to rows of character cells on the screen, then a coherent picture is displayed growing from the top downwards, giving a roller blind effect.  Data relating to the first significant row is sent initially followed by groups of character definitions and screen buffer data, the size of the groups dependent upon the characteristics of the transmission buffer.

Abstract: VAPOR RECOVERY        Abstract of the Disclosure Volatile liquid, such as benzene, isoprene, cyclopenta-diene, butadiene present as a vapor in a blanket gas released from a storage zone for the liquid is absorbed from the gas by use of an absorption oil, followed by contacting of the rich absorption oil with an immiscible extraction solvent in an amount much less than the absorption oil to extract absorbed volatile liquid and provide a lean absorption oil. The volatile liquid is recovered from the extraction solvent, for example, by stripping. By recovering the volatile liquid from the small amount of extraction solvent, rather than the absorp-tion oil, heating and cooling duties are decreased.

Abstract: RECOVERY OF PRECIOUS METALS FROM SPENT ALUMINA-CONTAINING CATALYSTS            Abstract The invention relates to the recovery of precious metals which is accomplished by melting an alumina-containing spent catalyst having therein a minor amount of a precious metal.  The melted alumina containing carrier material is heated to about 2100°C in an electric furnace.  The alumina material is poured from the furnace for utilization in abrasives manufacture.  The precious metal collects in the bottom of the furnace and is either poured off and allowed to solidify or allowed to solidify in the furnace.  In one embodiment of the invention, the steps of melting spent catalyst and heating to form a molten mixture is repeated a multiplicity of times with pouring off of the molten carrier material.  As a multiplicity of meltings and pourings are carried out, gradually there is an appre-ciable accumulation of the precious metals in the bottom of the furnace.

Abstract: ROTARY ACTUATOR                    ABSTRACT OF THE DISCLOSURE           A rotary actuator having an output drive rod mounted within an output sleeve that is rotated by a drive motor.  A driving mechanism for coupling the torque of the drive motor to the output sleeve includes a worm wheel that is mounted on the output sleeve so as to be freely rotatable relative to the output sleeve and a driving portion for transmitting power from the worm wheel to the output sleeve.  A clutch also is mounted on the output sleeve for rotation with the output sleeve.          The clutch however is axially movable along the output sleeve.          When in its first position, the clutch couples the drive portion of the drive mechanism to the output sleeve for transmitting the rotational force.  The clutch is normally biased into its first position for engagement with the drive portion of the drive mechanism.  A declutch mechanism is capable of causing the clutch to be moved into a second position out of engagement with the drive portion.  The declutch mechanism is used if the drive portion ceases to operate and the output sleeve is to be rotated by a hand wheel.  When the clutch is moved out of engagement with the drive portion, it is moved into a coupling arrangement with the hand wheel which in turn is able to manually drive the clutch and transmit a rotational force to the output-sleeve.  The clutch is retained in its second position until operation of the driving portion is resumed.  Upon resumption of the rotation of the driving portion of the drive mechanism, the clutch is automatically returned to its first position in engagement with the driving portion.
