Abstract: ABSTRACT OF THE INVENTION        Improved processes and products based on the discovery that metal atoms in complex relationship with complexing agents can be used to moderate the formation of organic salt seed crystals which promote an exceptionally well-ordered acicular growth of organometallic salts such as oxalates of the metal.  Some acicular, i.e. needle-like, products have particular utility for being reduced to ferromagnetic metal particles which retain a surprisingly large degree of acicularity and possess extraordinarily favorable properties  for use in magnetic recording applications.

Abstract: METHOD OF PREPARING STABLE CONDENSATION   PRODUCTS USING AN  ALCOHOL-ALKYLENE OXIDE TREATMENT AND PRODUCTS THEREFROM     Abstract of the Disclosure Products which are phosphorus containing oligomers having   linkages between phosphorus atoms and which are obtained by the self-condensation of .beta.-haloalkyl esters of pentavalent phosphorus acids or by condensation of these esters with an alkyl ester of a pentavalent phosphorus acid are treated with an alcohol having the formula ROH wherein R is a C1-C20 alkyl group or a substituted alkyl group and then with an alkylene oxide for a period of time after residual acidity has been neutralized, e.g., by treatment with an alkylene oxide, which is sufficient to enable the alcohol and the alkylene oxide to act upon labile groups contained in the condensed product and to neutralize any further acidity generated by the opening of such groups.          The stabilized product formed by this process when incorporated in a polyurethane foam gives a foam having superior green strength to a foam containing a condensed oligomer which is not so treated.

Abstract: BI-LEVEL CONDITION MONITOR USING  REVERSE-BIASED CONTROL DIODES     Abstract of the Disclosure An integrated circuit timer connected for astable oscillation in response to the charging of a timing capaci-tor to the threshold level of the timer, the timer energizing an indicator light when in oscillation.  A current bypass path with a diode therein is connected across the capacitor, the diode being reverse-biased to limit the level to which the capacitor may charge.  A condition-responsive voltage, proportioned to and variable with the level of a monitored condition, is used to maintain the reverse bias of the diode at a level below the threshold level of the timer and thereby prevent oscillation of the timer when the condition is on one side of a predetermined level, and used to maintain the reverse bias of the diode at a level above the timer threshold so the timer may oscillate when the con dition is on the other side of the predetermined level.          Two such timers are used when two predetermined levels of the condition are to be detected, and the timers may be set into oscillation in response to rising or falling changes in the monitored condition.

Abstract: APPARATUS AND METHOD FOR FORMING TAMPONS             AND ASSEMBLING SAME IN INSERTERS          Abstract of the Disclosure Apparatus and procedures for continuously forming rosette shaped tampons from aggregate containing tubular sacks or overwraps having withdrawal strings at one end and assembl-ing the tampons in inserters, the apparatus comprising rotary transfer mechanism for engaging the withdrawal strings of the sacks and sequentially delivering them to a rotary assembly turret having a multiplicity of assembling stations mounted around its periphery.  Each inserter comprises inner and outer parts, and feeding means are provided to individually feed and position an inner inserter and an outer inserter in holders at each assembly station.  Each station has a reciprocating string engaging rod which acts to remove a sack by its string from the transfer mechanism and positions the sack to be drawn upwardly by vacuum into an overlying annular inversion chamber wherein the sack is inverted into rosette shape by the action of a pressure-vacuum reciprocating inversion rod.  The shaped sack is then moved downwardly into an underlying compression cone wherein it is radially compressed and drawn downwardly into an underlying cylindrical compression chamber, whereupon the outer inserter is positioned to overlie the compression chamber and the inner inserter, which underlies the compression chamber, is moved upwardly by a reciprocating assembly rod which causes the inner inserter to push the compacted tampon upwardly into the overlying outer inserter, and at the same time the upper end of the inner inserter engages within the outer in-serter to complete the assembly.  The assembled inserter is then transferred from the assembly station to a discharge wheel for delivery to a collection station or other mechanism for wrapping, packaging, or the like as the rotary assembly turret completes its cycle of operation.

Abstract: ABSTRACT        A particle laden gas stream is cleaned by passing it through an all metal fabric including a base with pile fibers connected to the base.  The flowing gas forces the pile fibers to lie down upon each other to form a depth filter media adapted to entrap fine particles.  This depth filter media is cleaned to remove entrapped particles by passing air through the fabric in a direction counter to the direction the particle laden gas flows through the fabric. Consequently, the pile fibers tend to open and extend out-wardly from the base, permitting entrapped particles to be carried by the air from the fabric.  Apparatus including a tubular element made of an all metal pile fabric is also disclosed.  The tubular element has associated with it one or more nozzles adapted to blow air through the fabric along an incremental portion of the tubular element.  Consequently, a small portion of the fabric is cleaned while simultaneously the remainder of the fabric filters particles from the gas stream.

Abstract: DIESEL ENGINE INTAKE AIR PREHEATER FUEL CONTROL          ABSTRACT OF THE DISCLOSURE          A metering and control system is described for supplying fuel to a burner nozzle of a burner assembly which preheats intake air in a diesel engine.  Fuel for the control system is derived from the regulated pressure output of a fuel pump in the engine fuel supply system.  The fuel metering and control system includes a series of parallel flow lines connected between the fuel pump and the burner nozzle.  Each line has a metering orifice and check valve set to pass flow above a given pressure level.  For intermediate rpm flow is through one line and at high rpm flow is through both.  As a result, the fuel flow rate into the burner nozzle is directly proportional to engine rpm to provide a uniform nozzle preheat temperature over the full range of engine rpm.  Suitable control inputs are provided to initiate or terminate flow to the burner in response to selected engine operating parameters.  In addition, supplemental fuel flow may be provided during start up and/or cold operating conditions, again initiated or terminated by selected engine operating parameters.
