Abstract: Case 3169 00 PLASTIC SCREW GROMMET            Abstract A one-piece plastic screw grommet for use in mounting a screw relative to a blind bore located in a fibrous material. The grommet includes a shank portion and may have a laterally ex-tending head at one end. The shank has a first diameter portion adjacent the head complementary in size to the bore and connected to a smaller free end portion by a tapered intermediate portion.          Annular rings and axially disposed anti-rotation means, each having a radial extent greater than said bore, are carried on the exterior of said shank, A transverse slot extends through the intermediate and first diameter portions and a pair of flexible shouldered arms are disposed within the slots in opposed walls and extend axially toward said head end from their connection to said free end. A non-circular bore extends through the head end and first portion and blends into a cylindrical bore in said free end portion with the interior opposed arm surfaces of said arms having a concave cross section, the concavity having a radius of curvature substantially equal to the free end bore which equals the pitch diameter of the screw to be accepted therein. Each arm includes an interior and exterior taper and carries a flange at its free end for engaging the bore of the fibrous material to prevent inversion of said arms when subjected to pull-out forces.

Abstract: ANTI-SKID AND ANTI-SPIN      BRAKE SYSTEM     ABSTRACT OF THE DISCLOSURE A brake system for a vehicle having at least one wheel assembly comprises a master cylinder which is operable by an operator to communi-cate pressurized fluid to a wheel cylinder on the wheel assembly, thereby braking a rotatable member of the wheel assembly.  The brake system also includes a pressure storage member and a pump which communicates pressurized fluid thereto.  If a skidding condition is imminent, a control unit cooperates with a modulator valve to reduce the pressure communicated to the wheel cylinder, and when skidding is no longer imminent, the control unit cooperates with the modulator valve to communicate the pressure storage member to the wheel cylinder to reapply braking,  If a spinning condition is evident, the control unit cooperates with the modulator valve to communicate the pressure storage member with the wheel cylinder of the wheel assembly thereby retarding rotation of the spinning rotatable member.  In particular, a reservoir supplies fluid to the pump and the master cylinder, and the wheel cylinder is vented to the reservoir by the modulator valve upon an Imminent skidding condition or at the termination of a spinning condition.

Abstract: IMPROVED METHOD OF SEPARATING SALTS FROM SOLUTION     ABSTRACT OF THE DISCLOSURE     Disclosed is an improved method of separating a first salt and a second salt from an aqueous solution containing both salts and salt im-purities, where the solubility of the first salt increases more with increas-ing temperatures than the solubility of the second salt, and at least a portion of the salt lmpurities precipitates as slower settling rate crystals than the settling rate of precipitated second salt.  The solution is passed through a series of evaporators in which second salt and salt impurities are precipitated.  The bottom of each evaporator communicates with an elutraition leg into which precipitated salts settle, and into which a fluidizing liquid is introduced to carry precipitated salt impuri-ties back to the evaporators and from which second salt slurry is withdrawn. In the improved method, evaporator mother liquor effluent overflow having a temperature and salt composition near the temperature and salt composition of the solution in the evaporator communicating with the elutriation leg into which the fluidizing liquid is introduced is utilized as a fluidizing liquld (electriant).

Abstract: ABSTRACT OF THE DISCLOSURE A transducer assembly includes a first half wavelength double-dummy section having a pair of quarter wavelength ultrasonic horns and a driving element sandwiched therebetween.  A second half wavelength stepped amplifying section extends from one end of the first section and has a theoretical reso-nant frequency equal to the actual resonant frequency of the first section. When used as a liquid atomizer, the small diameter portion of the stepped amplifying section has a flanged tip to provide an atomizing surface of in-creased area.  To maintain efficiency, the length of the small diameter por-tion of the second section with a flange should be less than its length with-out a flange.  A decoupling sleeve within an axial liquid passageway elimi-nates premature atomization of the liquid before reaching the atomizing sur-face.

Abstract: ABSTRACT OF THE DISCLOSURE The Apparatus and System for Wireless Reception and Transmission of Coded Audio and/or Sonic Alarm Signal mobilizes people, by sounding an audible alarm, without the need for interconnection wiring through the system. The advancement in this art is accomplished by several factors: 1) By the use of coded audio signals, 2) The absence of radio waves, thus the absence for licensing, 3) A combination of audio alarm signals within hearing range, with coded transmission and reception of other related data, in a broader sonic range, for further processing, 4)  The absence of extensive labour for wiring.  The invention finds a utility is a broad range of alarm detecting, transmitting and receiving equipment and systems, such as fire, smoke, gas holdup burglary, telementery and control apparatus. As an illustration, one of the many applications of the said Apparatus and System, is described in conjunction with a conventional smoke detector. With the existing technology when a smoke detector is triggered by fire, all others are triggered via interconnecting wire, as well as the alarm monitoring and control unit, as a system.  This invention accomplishes both the detection and the transmission of the alarm without wiring.  When any one of the smoke detectors is triggered, it will sound an audible alarm and simultaneously transmit a coded signal to all other detectors in the system and to the central control and monitoring unit, to sound a general alarm within the whole system.

Abstract: BUFFERING DATA SIGNALS     ABSTRACT     The data bandwidth of a set of alternating buffers is broadened by switching or alternating between -the buffers when one of the buffers is empty and another buffer receiving signals has received a predetermined number of signals even though that receiving buffer is not yet full.  Data can be transferred in blocks of data bytes; then switching between buffers occurs on the address boundaries of such data blocks.  Therefore, switching or alternating between buffers can occur at a plurality of points within receiving one of the buffers.  The just described apparatus is useful for connecting a plural-port high-speed common unit to a plurality of data burst units such that each data burst unit has greater access to the high speed common unit.
