Abstract: DERIVATIVES OF BRANCHED-CHAIN MONOCARBOXYLIC ACIDS, ENGINE LUBRICATING OILS, LUBRICANT COMPOSITIONS FOR POLYMERS, WAX COMPOSITIONS IN WHICH THESE DERIVATIVES ARE INCORPORATED AND A PROCESS FOR PREPARING SAID BRANCHED-CHAIN MONOCARBOXYLIC ACIDS.     ABSTRACT           Derivatives of branched-chain monocarboxylic acids are dis-closed. Such derivatives are selected from the group consisting of a) esters of phenols or aromatic, aliphatic or cycloaliphatic alcohols  having at least 1 to 10 primary or secondary hydroxyl groups;          b) amides of ammonia or aliphatic, cycloaliphatic or aromatic amines having at least 1 to 15 primary or secondary amino groups;     c) salts of alkali metals or alkaline earth metals, amphoteric metals, heavy metals, of ammonium or of a compound containing a tertiary amino group.   The branched-chain monocarboxylic acids are telomeric acids obtained by the free radical addition of 1 mole of acetic anhydride to at least three moles of hexene and/or higher olefins containing up to 30 or more carbon atoms (C30+) in the presence of a trivalent manganese com-pound. The products of this invention are suitable for use in engine lubricating oils, lubricant compositions for polymers and wax composi-tions.

Abstract: ABSTRACT OF THE DISCLOSURE A flexible dispenser for dispensing the top sheet of flexible material from a sheaf or pile of flexible materials, e.g., paper, is pro-vided herein.  The dispenser includes an anchor for anchoring the dispenser, for example, in the form of a flange to be interposed between the top edge of a sheaf of paper, and the front wall of a receptacle containing such paper, and a flexible or partially flexible relatively elongate dispensing member, such dispenser extending over the top sheet of paper provided near its bottom edge with friction gripping substance on the top and bottom sur-faces.  When the dispensing member is moved rearwardly away from the point of ultimate emission of the paper, it will bow into  a convex configuration causing the top sheet of paper to assume a similar configuration, thereby causing it to lift away from the remainder of the material in the sheaf and become available to be grasped for removal from the receptacle.

Abstract: SPEECH/SILENCE DISCRIMINATOR FOR SPEECH INTERPOLATION          ABSTRACT OF THE DISCLOSURE       The speech/silence discriminator is used on a telephone line to distinguish between periods of speech and periods of silence.  A signal derived from the speech signal is, in the speech state compared to an adaptive threshold which is a fraction of the maximum, to be eventually quantized, reached by said signal during the period of speech which is considered; the speech to silence transition being determined when the signal decreases below said threshold level, the threshold level being determined during each speech period as a function of the maximum attained during the period.  The adaptive threshold has a minimum value of -60dBm.          It is also comprised of a noise level evaluation circuit which determines the threshold decision level ( ? -60dBM) for the transition from silence to speech which once reached, in the period of silence, enables the discriminator to go from the silent state to the speech state.  It is useable in speech interpolation systems.

Abstract: ABSTRACT OF THE DISCLOSURE        An accumulator type, rechargeable atomizing spray mechanism having a container for the liquid to be atomized, and further having an atomizer body, an atomizer head, an engaging member having a large-diameter hollow cylindrical portion.  The atomizer head is arranged to cooperate with skirt-like small-diameter and large-diameter pistons formed at a piston member.  The large-diameter hollow cylindrical portion of the engaging member is telescopically inserted within the peripheral wall of the atomizer head and is formed with a rod portion depending from the upper inside portion thereof.  Both the pistons are respectively telescopically inserted into the upper large-diameter and lower small-diameter cylindrical portions of the engaging member and the atomizer body.  The atomizer body has a longitudinal annular recess formed on the intermediate surface of the cylindrical guide portion thereof and a hole perforated at the connecting portion between the lower cylindrical portion thereof and the cylindrical guide portion thereof.  The engaging member has a longitudinal slot perforated at the upper portion of the rod-like valve body thereof.  The longitudinal slot operates to communicate the interior of the accumulator chamber with the passage of the suction tube when the valve body reaches its lowermost position to thus exhaust the residual pressure in the accumulator chamber into the liquid suction passage.  Thus, the atomizer of this invention can prevent the residual pressure from opacifying the liquid in white in the container.

Abstract: ABSTRACT OF THE DISCLOSURE           A steel strip heated to a temperature above recrystal-lization temperature is passed through a cooling unit including a plurality of cooling rollers cooled by cooling water flowing through the interior thereof.  The steel strip is caused to pass alternately about upper and lower surfaces of the cooling rollers.  By raising and lowering alternate cooling rollers, the contact area, i.e., the contact time between the strip and the cooling rollers is varied to change the cooling rate.  When the cooling rollers are separated from the strip, cooling water is filled into the cooling unit to directly cool the strip.          Cooling gas may be ejected against the strip before it enters into the cooling unit.  Where the strip is cooled indirectly, so that it is passed about a series of cooling rollers cooled by water flowing through their interior, it is possible to cool the strip without forming oxide films thereon.  The type of cooling is selected according to the type of the steel strip.          With this method and apparatus it is easy to adjust the cool-ing rate of a steel strip.

Abstract: ABSTRACT OF THE DISCLOSURE An elongated conveying device suitable for connecting spaced work stations, for example, receives a flow of objects such as component parts at an appropriate entrance. The objects are placed on a pair of spaced stationary rails from which the objects are lifted, carried forward and then returned to the stationary rails by a pair of movable rails which is rotator in a circular-shaped cycle.  With each cycle of the movable rails, the objects are stepped from the entrance to an exit located some distance away.  Because the rate of object input may vary from the rate of part dis-charge, the conveying device may include holding stations adjacent to the exit allowing the objects to accumulatate in a damage resistant manner until removed from the conveying device.
