Abstract: ABSTRACT OF THE DISCLOSURE   An aqueous ferrous sulfate waste stream is converted into sludge and improved water effluent by a preferably ambient indoor temperature and pressure flow process comprising:  turbently mixing said stream with a sub-stantial excess of gaseous oxygen and a small excess of impalpable calcium carbonate in a reaction zone until the iron content of said stream is vir-tually all sludged; classifying resulting sludge into a coarser solids frac-tion ( a portion of which is recycled to the sludging operation) and an aqueous suspension of finer solids; and separating finer solids from such aqueous suspension.  As such streams usually contain free sulfuric acid, it is desirable to first precipitate from the stream a primary gypsum product by neutralization prior to such sludging operation.

Abstract: Abstract of Disclosure The invention relates to input and output circuits for multiplexing equipment, especially the kind used in telephone systems where nominally identical clocking signals have natural deviations of timing (called "plesiochronous" signals).  The invention uses the "justification" principle to ensure the clock synchronization of plesiochronous numerical signals.  A buffer memory, with independent writing and reading capabilities, is formed of two first in-first out or "FiFo" memories connected in series.  The request signal for a "justification" is made when a connection is completed between an IR (Input-Ready) output of the second FiFo memory and an input SO (Shift-Out) of the first FiFo memory, if there is an undesirable phase shift between the input and output clocking system.  A reading clock oscillator has a frequency which is governed by a governing signal, which depends, at least in part, upon the electrical state existing in the series connection between the IR output of the second FiFo memory and the input SO of the first FiFo memory.  The receiving and demultiplexing system uses a similar buffer memory to extract any "justification" signals which were added on transmission. A phase-locked loop including a quartz-controlled oscillator controls the output clocking of the demultiplexer.

Abstract: COMMUTATING CAPACITOR CHARGE DETECTION      CIRCUIT AND METHOD ABSTRACT OF THE DISCLOSURE             A circuit and method is disclosed for detecting the presence of charges of appropriate magnitude and polarity on commutating capacitors of an inverter that converts a DC output current to a drive current of variable magnitude and frequency for driving an AC electric motor producing controllable rotation and torque.  The presence of charges of appropriate magnitude and polarity is detected by measuring the voltages across the conduction controlled rectifying devices in the inverter.  In addi-tion, the existence of condition controlled rectifying devices in the conducting state is determined by measuring the magnitude of the DC output current.  An output signal is generated when the charges of appro-priate magnitude and polarity are detected, which output signal is effective to allow the inverter to generate normal drive current.  The absence of the output signal is effective to force the magnitude of the DC output current below a predetermined magnitude value and is effective to prevent the sequencing of gating signals to the inverter, whereby the drive current is such that the motor produces substantially zero rotation at substan-tially zero torque.

Abstract: FIRE-RESISTANT DEMOUNTABLE PARTITION STRUCTURE     ABSTRACT OF THE DISCLOSURE         A fire rated, demountable partition structure is disclosed which provides H-shaped studs having a core of combustion-resistant insulation material and opposed channel-shaped metal members secured to opposite faces thereof.  Spline clips secure one side of the stud to the panel at joints therebetween.  Each clip includes a lateral projection extending with a close fit into a kerf in the edge of the panel and a reverse bend providing opposed clip walls which fit along opposite sides of an adjacent flange on the stud.  If the partition is exposed to a fire or the like, which tends to cause shrinkage of the panels and opening of the joints, the core of the stud bridges the joint and prevents direct exposure of the metal channel elements of the stud to heat or water through the opened joint.  The spline clips are free to expand if the clips are subjected to greater heat than the channel members so that the stud is not caused to bow toward the fire side of the partition.

Abstract: ABSTRACT OF THE DISCLOSURE         A chuteless rotary scything mulching lawn mower is described which is particularly adapted to be powered by an electric motor including sealed motors.          The cutting chamber includes a toroidal portion bounded by concentric skirt walls wherein the cross sectional area of the toroid increases towards the inner skirt.  The inner skirt slopes downwardly towards the axis of the cutting blade, and terminates close thereto so as to reduce air leakage from the toroid.          Air passage openings are provided into the housing on the axial side of the inner skirt through which cooling air is drawn for the motor.  This air stream combines with air from the toroidal chamber which is redirected by the inner skirt wall to distribute grass cuttings over a comminuting portion of the blade.  The blade is sharpened to a chisel edge along the upper surface thereof, the bevelled surface of the chisel edge fucntioning as an air propelling surface.  The efficiency of the housing permits blades with less twist to be employed, reducing the incidence of blade cracking.
