Abstract: A monodisperse aerosol generator forms a stable jet of liquid at a velocity allowing columnar breakup into droplets of uniform size and spacing. To prevent degradation of the monodisperse aerosol, it is disposed by entrainment in a high velocity gaseous stream. To provide an interface for direct injection onto a particle collection device or into an infrared or Raman spectrometer or to interface a liquid chromatograph with a particle collection device or an infrared or Raman spectrometer, the generator is followed by a desolvation chamber operation at about atmospheric pressure and a multistage pressure reducer which evacuates solvent vapor and gaseous medium to form a high momentum, solvent-depleted solute aerosol beam which is input into the infrared or Raman spectrometer.

Abstract: A compact disposable diaper is disclosed having flap-like compartments on opposed ends of the rear portion of the diaper assembly for retaining cleansing and drying towelettes for use in clean up of a child when changing the diaper.

Abstract: A compact pneumatic air filter system for filtering conditioned air laden with dust and reusable debris is disclosed, which has an initial filter stage for collecting reusable debris from air and separately storing it for reuse, and a secondary filter system for collecting remaining dust from air for disposal and re-releasing conditioned air to a work environment. The system utilizes alternating positive and negative air pressures to move debris and dirt to appropriate storage spaces within the system, and to move filtered air back into the work environment by migration through filter walls, thereby retaining the conditioned property of the filtered air.

Abstract: A surge arrester of modular form, including a metal oxide varistor disk having a coaxial shunt gap located within the disk. The metal oxide varistor disk has a hole located essentially through the center of the disk and includes top and bottom electrode plates having centrally located projections which protrude inwardly of the disk into the hole of the disk, thereby forming a shunt gap within the disk. The module may be used unhoused in under-oil applications or as a component part of a housed arrester. For under-oil applications, the electrode plates are solder sealed to the disk providing a seal preventing oil or moisture from entering the hole in the shunt gap. As an alternate embodiment the surge arrester module may include a series of two or more of such disks stacked between the top and bottom electrode plates.

Abstract: Laterally shiftable front and back needle bars are slideably mounted on a main needle bar, the front needle bar carries a front row of needles and a back needle bar carries a back row of needles. Cut pile loopers cooperate with the needles of the back row and cut-loop loopers cooperate with the needles of the front row. Needles in the front row are larger and handle larger size yarns than needles in the back row and a yarn feed control dictates whether yarns in the front needles make low loops or high cut piles.

Abstract: A conventional tufting machine is provided with front and back juxtaposed, laterally shiftable, needle bars positioned on a common needle bar support, the needles of the front needle bar cooperating with loop pile loopers and the needles of the back needle bar cooperating with cut-loop loopers. Yarn feed controls respectively feed yarns to the needles according to individual prescribed patterns. The needle bars are respectively shifted laterally according to individual prescribed patterns.Tufted fabric produced by the machine is illustrated in which the loop tufts produced by the front needles are of relatively small cross section while the selectively cut or loop tufts produced by the back needles are of relatively large cross section. The large loop tufts are interspersed with small loop tufts due in part to lateral shifting of the needles.
