The appara-tus includes a filter element for receiving the gas flow and substantially trapping the ammonium nitrate particles.  Injec-tion nozzles inhabit a conduit which delivers the exhaust gas flow to an inlet of the filter and inject a water mist into the gas flow which mist acts to irrigate the filter.

Abstract: ABSTRACT OF THE DISCLOSURE     A collapsible revolving door is described and in-cludes upper and lower latching mechanisms which normally retain leaves of the door in radially disposed, angularly spaced positions but which allow the leaves to collapse flat against one another in the event that abnormal forces are applied thereto.  Each latching mechanism includes one latch member for each leaf.  The latch member is mounted on a pivot pin for the leaf so that the latch member will turn with the member from a normal radial position to a collapsed position.  The latch member is coupled at a posi-tion generally centrally of its length to the pin so that respective end portions of the latch member are defined on opposite sides of the pin.  The latch member is retained in its normal position by spring biassed detent means acting between each end portion of the latch member and the housing.          The detent means are designed to release when abnormally high forces are applied to the leaf so that the leaf can move to its collapsed position.

Abstract: ABSTRACT OF THE DISCLOSURE            The disclosure is directed to a method and apparatus for determining the velocity of a material within a body, and which is also capable of simultaneously imaging sections of the body.  In the velocity-determining method, a focused beam of ultrasound is directed, over a given aperture, toward the skin of the-body, the central ray of the focused ultrasound beam being oriented substantially normal to the skin.  The ultrasound beam reflected from the body is received over the same aperture.  Preferably, the steps of directing and receiving the ultrasound employ the same single transducer, and focusing is achieved using a focusing lens.  Beat frequency signals are detected in the received beam,these signals resulting from the beating of Doppler effect components reflected from the moving material, for example, blood corpuscles of moving blood within the body.  Velocity-representative indications, for example, audio or video presentations, are then generated as a function of the detected beat frequency signals.  The detected beat frequency signals are beats between Doppler effected portions of the received ultrasound beam which have frequency components above and below the frequency of the originally directed ultrasound beam.

Abstract: Abstract of the Disclosure There are provided circuits for removing the equivalent pulses from the video signal.  A composite sync signal separated from a video signal is applied to a gate circuit, so that only horizontal sync pulses are extracted.  The gate pulse applied to the gate circuit is formed in the following manner.  Clock pulses of a frequency 175/4 fH (fH:  a horizontal scanning frequency and about 15,734 KHz), for example, is frequency-divided in-to a signal of a frequency 175/256 fH by a frequency divider.  A reset circuit processes the frequency-divided output signal, the delayed sync signal and the inverted composite sync signal to form pulses in synchronism with the horizontal sync pulses.  The pulses thus obtained reset the frequency divider.  At the same timing of the pulse generation from the reset circuit, a gate pulse generating circuit generates pulses whose pulse widths are longer than the pulse widths of the horizontal pulses, which in turn are applied as tile gate pulse to the gate circuit.
