Abstract: ABSTRACT OF THE DISCLOSURE      New and improved catalysts for polymerizing alpha-olefins of formula CH2 = CHR in which R is a C1 to C6 alkyl, more particularly propylene, mixtures of the alpha-olefins, and mixtures thereof with ethylene are disclosed. The catalysts are prepared form Al alkyl compounds and a solid product including a Mg dihalide and reaction products of said halide with at least one Ti compound and an electron donor compound which is an ester of and organic or inorganic oxygenated acid. The improvement consists in providing catalysts prepared from components (a) and (b) molar ratios between the alkyl Al compound and the Ti compound of component (a) in the range of from 1 to 30, preferably from 2 to 20, and in which if the alkyl Al compound is complexed with an electron donor compound, the latter is used in reduced amounts such that at least 85% of the alkyl Al compound is in a form not combined with an electron donor compound, i.e., catalysts which are highly active and highly sterospecific but which involve a lower consumption of alkyl Al compound with respect to the Ti compound than has been required in the case of various prior art catalysts and which make it possible to use a lower amount of electron donors compound complexed with the Al alkyl compound.

Abstract: Disclosure 5333 PROCESS FOR RECOVERING DISSOLVED IMINODIACETONITRILE                FROM EFFLUENT LIQUORS          Abstract of the Disclosure A process for recovering iminodiacetonitrile (IDAN) values from an aqueous IDAN solution comprising: (a) extract-ing the aqueous IDAN solution with methylene chloride to dissolve a portion of IDAN in the methylene chloride to form a methylene chloride solution of IDAN; and (b) separating and recovering the IDAN values from the methylene chloride.     In an alternative embodiment the IDAN values can be separated from the methylene chloride solution of IDAN by extracting the methylene chloride solution with an aqueous alkali metal hydroxide solution to form water-soluble di-alkali metal iminodiacetate (IDAM2 wherein M is an alkali metal cation) which remains in the aqueous alkali metal hydroxide solution.  The IDAM2 can be recovered from the alkali metal hydroxide solution by conventional methods (e.g., by treating with a strong acid to precipitate imino-diacetic acid (IDA)).     Each extraction (the extraction with methylene chloride and the extraction with aqueous alkali metal hydroxide solu-tion) can be conducted as a batchwise extraction or as a continuous counter-current extraction.

Abstract: ABSTRACT OF THE DISCLOSURE     A magnetic latch for a clapper type contactor having an electromechanical system comprising an operating coil, a coil core, a magnet frame, and an armature includes a magnetic latch plate.  The magnetic latch plate includes a stop portion having a pair of ears mounted on a pivoted contact arm.  The stop portion of the latch abuts against the magnet frame before energization of the coil so that a flux path includes the core, the magnet frame, the magnetic latch, the armature and the air gap between the armature and core of the coil.  After the coil is energized and the current begins to build the magnetic latch saturates an additional parallel flux path travels from the core to the magnet frame through the heel air gap of the armature through the armature to the air gap between the armature and core of the coil until the combined force across the heel air gas and the air gap between the magnet frame and armature and the armature and the core, respectively, are greater than the force between the magnet frame and the magnetic latch, then the armature closes against the core.  The amount of latch force desired is controlled by adjusting the cross-sectional area of the magnetic latch.

Abstract: METHOD FOR PRODUCTION OF HIGH MOLECULAR WEIGHT POLYESTER WITH LOW CATALYST LEVEL AND LOW CARBOXYL CONTENT                ABSTRACT OF THE DISCLOSURE             A high molecular weight polyester is dis-closed, having a low carboxyl content, and utilizing a low catalyst level, produced by a two-stage process; a melt process until the intrinsic viscosity of the prepolymer reaches about between 0.15 and 0.45 dl/g, and a solid state polymerization in a fluidized bed until the intrinsic viscosity of the polycondensed polymer reaches at least 0.60 dl/g.  The melt process employs addition of excess initial glycol, delayed addition of excess glycol, and delayed addition of catalyst, in any combination, to achieve a low car-boxyl content polyester prepolymer capable of use in the fluidized bed solid state polymerization. This prepolymer with a minimal carboxyl content achieves a maximum solid state polymerization rate in a fluid-ized bed.  This prepolymer also permits the use of a very low catalyst level to achieve high product pur-ity and still maintains economically satisfactory polymerization rate.Stability and color clarity of the polycondensed product is obtained by this method.

Abstract: Abstract A semiconductor substrate is selectively etched to produce a spaced succession of narrow, shallow trenches separated by narrow silicon mesas.  Silicon oxide is chemical-vapor-deposited on the horizontal and vertical surfaces of the etched structure to a thickness equalling the width of a desired silicon oxide mask.  The mask is used for etching multiple deep trenches in the substrate, the trenches being separated by thin walls of silicon.  The thickness of the walls is uniformly equal to and determined by the thick-ness of the deposited silicon oxide mask.  The deposited silicon oxide is reactively ion etched away from the hori-zontal surfaces, leaving the oxide only on the sidewalls of the shallow trenches.  The silicon is deeply etched, using the remaining oxide as a mask.  Boron is ion im-planted and the resulting structure is thermally oxidized sufficiently to completely oxidize the silicon under the deposited oxide mask and to oxidize the silicon surfaces at the bottoms of the trenches.  The remaining trench volume is filled in with chemical-vapor-deposited silicon dioxide.

Abstract: Abstract of the Disclosure An improved method and grinding machine are used to grind lobes on a camshaft.  The grinding machine includes a longitudinally extending rocker bar which is pivotally mounted on a work table or carriage.  A headstock and tailstock are connected with the rocker bar to rotatably support the camshaft as the cam lobes are ground by a grinding wheel.  A control assembly includes a motor which is operated to pivot the rocker bar from a retracted or loading position through an index position to an operating position in a range of operating positions.  Immediately before the rocker bar reaches the range of operating positions, the speed of the motor is reduced to effect a corresponding reduction in the speed of movement of the rocker bar.  In addition, the motor actuates a biasing assembly to urge the rocker bar toward the camshaft with a relatively large force during a rough grinding operation and a reduced force during a finish grinding operation.          During the rough and finish grinding operations, a master cam assembly and follower cooperate to move the rocker bar in the range of operating positions as a function of the desired cam lobe configuration.  The cam follower is movable into alignment with a selected one of a plurality of cam elements in the master cam assembly by a motor which is mounted on the carriage.  A stop member is utilized to stop the rocker bar when it has moved away from the grinding wheel to the index position.  This enables the cam follower to be aligned with a selected master cam element between the grinding of successive lobes on the camshaft without moving the rocker bar all the way back to the loading position.  When the grinding of the camshaft is completed, the stop member is retracted to enable the rocker bar to be pivoted to the loading position.
