Abstract: ARRANGEMENT FOR DETERMINING LIQUID AND GAS FLOW RATES     ABSTRACT OF THE DISCLOSURE      By means of sonic or ultrasonic energy, flow rate is determined as a linear function of the difference between two frequencies by taking measure-ments in the direction of flow and in the direction opposite thereto. Trans-ducers are used alternately as generators and pickups. To this end, the transit time difference is determined by means of a phase detector, and the frequencies of two oscillators are readjusted in accordance with the results of the measurements. The difference frequency can be indicated and calibrated in flow rate, and the number of cycles can be counted, the flow volume being directly proportional thereto.

Abstract: ABSTRACT OF THE DISCLOSURE           Scum skimmer apparatus having a skimmer blade slideably disposed on support rods extending downwardly from an oscillating bridge which is moveable over the clarifying tank in a biological waste treatment plant.  An air tight ballast chamber is secured to the skimmer blade having a source of air communicating with the ballast chamber, the source having a valve for controlling the air flow.  As the bridge moves toward the scum trough at one end of the clar-ifying tank the air is evacuated from the ballast chamber, allowing the blade to engage the surface of the liquid.  Upon moving away from the scum trough air is pumped into the ballast chamber providing a buoyancy force which raises the skimmer blade away from the surface.  When the opposite end of the clarifying tank is reached the skimmer blade is lowered back to the water by venting the air out of the bal-last chamber.  A circular treatment tank is provided having spaced concentric walls with partitions therebetween forming alternate aeration and clarifier zones on the periphery thereof with a central digester zone such that separate aeration zones may be used for organic carbon removal and nitrogen removal.

Abstract: A METHOD FOR FORMING DIELECTRIC ISOLATION      COMBINING DIELECTRIC DEPOSITION AND THERMAL OXIDATION                     Abstract of Invention In the fabrication of integrated circuits, a method is provided for forming recessed silicon dioxide isolation in which the "bird's beak" problem associated with conventional silicon dioxide-silicon nitride composite masking structures is minimized.  A conventional composite mask comprising a bottom layer of silicon dioxide and an upper layer of silicon nitride having a plurality of openings defining the regions in the silicon substrate which are to be thermally oxidized is formed on the substrate.  Recesses are then etched in the silicon substrate in registration with the openings in the composite mask.  The silicon dioxide layer should be, in effect, over-etched to extend the openings in the silicon dioxide to greater lateral dimensions than the openings in the silicon nitride layer whereby the silicon nitride layer at the periphery of the openings is undercut.    A layer of a material capable of blocking the oxidation of silicon and having a greater etchability than silicon nitride is then deposited in said recesses and covering said undercut portions of said silicon nitride masks.  At this point the structure is blanket etched to remove said blocking material from the portions of the recesses not under said silicon nitride and to, thereby, expose the silicon in these portions.  Finally, the structure is thermally oxidized so that the exposed silicon in the recesses oxidizes to form recessed regions of silicon dioxide substantially coplanar with the unrecessed regions of the silicon substrate.  Because of the undercutting and the deposition in the undercut portions of the recesses of the blocking material, the "bird's beak" effect is minimized.

Abstract: Abstract of the Disclosure The present invention is directed to a demodulator for demodulating a wideband spread spectrum four-phase PSK          (phase shift keyed) modulated carrier signal wherein the phase modulation was in response to an encoded data signal and wherein the encoding of the data signal and spreading of the spectrum was accomplished by the mixing of the data sig-nal with a pseudo-random pulse sequence (PN-sequence).         The demodulator is comprised in part of a generator means for providing a pseudo-random pulse sequence correspond-ing to the sequence used to encode the data signal; and an encoding means for converting the provided PN-sequence into a four-phase PN sequence.  A correlation means correlates the generated four-phase PN sequence against the received four-phase PSK modulated carrier signal to provide a two-phase collapsed spectrum signal.  A switching means inter-posed between correlation means and the generator means switches two of the four phases of the four phase PN-se-quence signal applied to the correlation means until proper phasing is achieved.

Abstract: ATTACHMENT MEANS OF AN OBJECT TO A SUPPORT              ABSTRACT OF THE INVENTION    A shock-, vibrations- and  tampering-proof attachment means of an object, such as a signal producing insert of an ionization alarm system coaxially and non-rotatably to a support, such as for land-,marine-and air vehicles provides a spring assembly with a spring and biased coaxial protrusion in the bottom of the object with a helically wound canal running through the protrusion having end orifices in its surface .  The support is provided with a U-shaped fork fixed with its yoke in it.          A connecting means equipped with a rod traverses the protrusion perpendicularly to its axis. The rod is fastened to both free ends of the yoke. Optimum shapes and dimensions of the respective parts are established, also with the view of maintaining a minimum size of the object itself. The object with the fixed protrusion is mounted by rotation thereof to the support, thus hiding the attachment means and making them vibration proof and inaccessible from the outside. An attempt to disassemble the attachment by re-rotation of the object relative to the support results only firstly in moving the point of engagement of the attachment upwardly toward the vertex of the canal, simultaneously distancing the protrusion from the spring assembly and subsequently reversing the axial motion of the protrusion toward the spring assembly with the point of engagement of the attachment continuing to move to the end of the canal or channel, thus preventing axial separation and a reverse rotation without excessive force.

Abstract: ABSTRACT OF THE DISCLOSURE          The specification discloses a process for preparing resinous particles for a coating composition including the following steps.  Firstly, a resin containing an ionic group, or a mixture of another type of resin and a dispersing agent containing an ionic group, is dissolved or  ispersed in water by treatment with a neutralizing agent for the ionic group.          Secondly, the resin is removed from solution or dispersion by the use of a powdering agent and the resin thus deposited is pulverized in the aqueous medium.  Thirdly the powder thus formed is removed from the aqueous medium.  The resulting powder can then be used to preparing coating compositions or can be used directly for spray coating.  The advantage of this type of powdered material is that it is produced entirely without the use of organic solvents and their attendant pollution, health and fire hazards etc.

Abstract: RCA 70,849 TELEVISION TUNING SYSTEM WITH PROVISIONS FOR RECEIVING RF CARRIER AT NONSTANDARD FREQUENCY           Abstract of Disclosure A tuning system for a television receiver includes a phase locked loop for tuning a local oscillator to the nominal local oscillator frequencies required to tune the receiver to RF carriers at standard broadcast frequencies allocated to the various channels a viewer may select.  The tuning system also includes an automatic fine tuning (AFT) frequency discriminator fox tuning the local oscillator to minimize any deviation between the frequency of an actual picture carrier and the nominal picture carrier frequency.          If the receiver is coupled to a television distribution system which provides RF carriers having nonstandard freq-uencies arbitrarily near respective ones of the standard broadcast frequencies, when the phase locked loop has achi-eved lock at a nominal frequency, a mode control unit selectively couples the discriminator and a frequency drift control circuit to the local oscillator.  If the frequency of the local oscillator drifts more than a predetermined off-set from the frequency synthesized under phase locked loop control because no carrier has been detected by the discrim-inator, discriminator and drift control are terminated so that the receiver will not be tuned to an undesired carrier such as, for example, the lower adjacent channel sound carr-ier, and phase locked loop control is reinitiated to synthe-size a local oscillator signal having a frequency incremented from the frequency of the originally synthesized local oscillator signal by a predetermined amount.  After the phase locked loop is locked at an incremented frequency, discriminator control is again initiated.  If, during this cycle of discriminator control, the local oscillator again drifts more than the predetermined offset from the RCA 70,849 incremented local oscillator frequency because no carrier is detected by the discriminator, phase locked loop control is again reinitiated to synthesize a local oscillator signal having a frequency decremented from the frequency of the originally synthesized local oscillator signal by the pre-determined amount.  If during any discriminator control cycle the local oscillator has not drifted further than the predetermined offset because the discriminator has tuned the local oscillator to a carrier within the predetermined offset, phase locked loop control is not reinitiated and the tuning sequence is complete.     -1a-

Abstract: ABSTRACT OF THE DISCLOSURE           Rectangular frame for suspending a filter element in a cassette is made of U-shaped channels open at the periphery of the frame.  The filter element includes a collar complementary with the frame, the collar including four sleeves extending almost the entire length of the respective sides of the collar.  Longer sides of the channels are provided with longitudinal flanges reducing the size of opening of the respective channel.  Two L-shaped locking bars are arranged to engage the collar sleeves such that one,longer leg of the respective bar passes through the respective longer sleeve of the collar and through the longer channel, said flanges of the channel preventing the sleeve surrounded leg of the locking bar from escaping from the channel.  The other, shorter leg of the bar releasably presses adjacent shorter sleeve to turn same inwardly into the opening of the shorter channel of the frame, without passing through the shorter sleeve. The two L-shaped locking bars thus releasably secure the filter element frame.  The invention facilitates replacement of filter elements.
