Abstract: ABSTRACT OF THE DISCLOSURE       A system and method for controlling energy input to a series of electrostatic dust separator devices having a common gas inlet and a common gas outlet.  A detector unit is disposed in the gas outlet to detect the dust concentration or evaluate the actual dust loss in the exhausted gas.  Energy control circuitry is coupled with each separator device to control the energy input to each separator device.  The control circuitry is actuated by an actuating device to first change and then restore the energy input to each of the separator devices in a selected sequence to thereby change and restore the dust concentration in the exhausted gas.  Computation circuitry is coupled with the detector unit to compute the change in dust concentration resulting from a certain change in energy input to each of the separator devices in the sequence.  Calculator circuitry selects the separator devices producing a desired change in the dust concentration in response to the certain change in energy input to each of the separator devices.  The actuating device is coupled with the calculator circuitry and the control circuitry of each separator device to change the energy input to at least one selected separator device producing the desired change in dust concentration.

Abstract: LOW SPEED LASER SCANNING APPARATUS            Abstract of the Disclosure Apparatus for generating a scanning pattern for the omni-directional reading of bar code indicia. In one embodiment, a rotating mirror assembly is imaged onto itself by a lens and mirror combination which introduces a light displacement of the image resulting in the displacement of the input beam from the angle of incidence on the mirror of the input beam.  Using an array of such lenses and mirrors, a plurality of spa-tially displaced light beams of substantially equal power are generated without the use of specialized beam-splitting coatings for use in the generation of a scan pattern.  In a second embodiment, the array of mirrors deflects a laser beam two or more times at the same facet of a rotating mirror assembly to increase the angular velocity of the deflected beams, thereby enab-ling the mirror assembly to be rotated at a lower speed while still maintaining the required angular velocity of the deflected output beam.

Abstract: HEAT-RESISTANT, WEAR-RESISTANT, AND HIGH-STRENGTH ALUMINUM ALLOY POWDER      AND BODY SHAPED THEREFROM               ABSTRACT OF THE DISCLOSURE     The present invention relates to an aluminum alloy powder.     Aluminum alloy powder having a high Si content is known but its heat resistance, wear resistance, and strength are poor.     The aluminum alloy powder according to the present invention is characterized in that it contains from approximately 10.0% to approximately 30.0% of silicon and at least one element selected from the group consisting of from approximately 5.0% to approximately 15.0% of nickel, from approximately 3.0% to approxi-mately 15.0% of iron, and from approximately 5.0% to approximately 15.0% of manganese, the silicon crystals in the aluminum alloy powder being 15 µm or less in size.  Due to the high content of nickel, iron, and manganese, the matrix is hardened and strengthed by the presence of finely dispersed intermetallic compounds and the silicon crystals, and thereby the high-temperature characteristics are improved.     The shaped body, e.g., a hot-extruded shaped body, according to the present invention comprises an aluminum alloy having the above composition powder of the present invention and preferably a solid lubricant, the silicon crystals in the shaped body being 15 µm or less in size, and the intermetallic compounds 20 µm or less in size being finely distributed in the shaped body.     The high-temperature characteristics of the shaped body are very excellent, thereby enabling it to be used as a cylinder liner which is inserted into an aluminum cylinder block body by casting the body.

Abstract: ABSTRACT       Conventional water wheels are rarely used to generate hydroelectric power due to the low efficiency caused by turbulence and splashing when water hits the blades, by excessive back pressure generated in housings which complete-ly enclose the water wheels, and by leakage of hydraulic pressure.  This invention relates to a water wheel housed in a flow-duct which encloses only the blades of the water wheel, and which directs the flow of water onto the blades, thereby minimizing splashing and turbulence.  The flow duct is designed to discharge the water at a point where the water ceases to exert a downward rotational torque on the wheel.          Novel seal means are provided around the periphery of the flow-duct so as to minimize leakage of hydraulic pressure.

Abstract: ABSTRACT OF THE DISCLOSURE    An improved scannable latch circuit allows  its output  to  be monitored during effectively 100% of the system clock cycle.  The circuit further provides dual isolated outputs, one of which is used as a latch output and the other of which is used as a shift-register output.  A computer system, in which the scannable latch circuit is used,  in conjunction with combinatorial logic and error detection circuitry, may thus monitor the latch output, which is not loaded down by the shift register output,  for error detection and other purposes without having to slow down the system operating speed.  A preferred embodiment of the scannable latch circuit includes first, second, and third latch elements.  When operating a latch circuit, the first  latch element operates as the  "master" and the second latch  element  operates  as  the  "slave"  of  a  master/slave  latch circuit.  When operating as a shift register circuit, shift-in data is  coupled  to  the  second  latch  element,  and  this  second  latch element  operates  as  the  "master"  and  the  third  latch  element operates as the "slave" of a master/slave latch through which data is selectively shifted by appropriate clock signals.

A circuit for recovering the carrier of an ampli-tude- and- phase-modulated input signal (in particular QAM signal) is provided with a frequency-controlled oscilla-tor for producing the carrier, with a quadrature detector for supplying signals representing the amplitude of the input signal projected on two quadrature components P and Q of the carrier signal produced by the oscillator and for thus determining the modulation states of the input signal, and with correction means for forming a correction signal for the frequency control of the oscillator on the basis of output signals from a circuit which determines zones in the plane of the quadrature components P and Q. To provide for a satisfactory operation also in the presence of se-lective fading, the correction means comprise a weighting circuit connected to the zone-determining circuit for producing the correction signal in accordance with distinct weights allocated to the respective zones defined by the zone-determining circuit.

Abstract: PIPE COUPLING Abstract of the Disclosure A pipe coupling for the joining of plain end pipe that includes an annular gasket and a compressible lock ring at each end of the coupling between a tubular middle ring and an annular follower.  Bolts extending between the opposite followers are effective when tightened to compress both the gasket and lock ring into their operative relation for sealing and gripping a coupled pipe end, respectively.  An annular recess contained in the backface of the gasket affords a clearance of controlled dimension initially about the juxtaposed portion of the lock ring.  The clearance functions when the bolts are tightened to enable gasket sealing pressure to be achieved about the pipe sequentially before an effective grip on the pipe is attained by the lock ring.
