Title: Liquid membrane modules with minimal effective membrane thickness and methods of making the same
Inventor: CARROLL ROBERT H
IPC: B01D69/00
Filed: 1992-04-13
Abstract: ABSTRACT      Modules for use in fluid separations, especially contained liquid membrane separations, exhibit minimal effective membrane thickness.  The modules have a module case and a bundle of a dense plurality of hollow fiber membranes contained in the case.  One set of the fiber membranes in the bundle constitutes feed-fibers while another set of the fiber membranes in the bundle constitutes strip-fibers for use in contained liquid membrane separations.  The feed-fibers and strip-fibers are disposed within the elongate module case in opposite generally wave-like paths such that the feed-fibers and strip-fibers converge at generally lengthwise-separated crossing regions within the module.  This disposition of the feed-fibers and the strip-fibers minimizes the effective membrane thickness value of the module as compared to conventional contained liquid membrane module thereby enhancing the efficacy of fluid separations.

Title: Recovery of condensable organic compounds from inert streams laden therewith
Inventor: KOVACH J LOUIS
IPC: B01D53/04
Filed: 1992-05-11
Abstract: RECOVERY OF CONDENSABLE ORGANIC COMPOUNDS      FROM GAS STREAMS LADEN THEREWITH                                     ABSTRACT OF THE DISCLOSURE The present invention relates to the recovery condensable organic compounds formgas streams laden therewith. The streams may be process gas containing high concentrations of organic contaminants, or inert gas employed in regenerating adsorbent beds used to strip and concentrate organic contaminants from process or humid process gas streams. Where at least a pair of adsorbent beds are used, a first adsorber is operated until the organic contaminant is detected at a preset "breakthrough" level in the outlet gas. The outlet gas is then passed through a second adsorber until the level of organic contaminant is determined to be at approximately the level of organic contaminant in the humid contaminant-laden gas being passed into the first adsorber, and at which point part of the less well-adsorbed water has passed into the outlet gas of the first adsorber. At such time, passage of the humid contaminant-laden gas into the first adsorber is discontinued and, instead, the humid contaminant-laden gas is passed into the second adsorber. During passage of the humid contaminant-laden gas into the second adsorber, the first adsorber is regenerated. To recover the organic contaminant desorbed from the adsorbent bed upon its regeneration, the regenerative gas laden therewith may be expansively cooled in a turbine expander to effect a condensing separation and a recovery of the condensable organic compound from the relatively noncondensable inert gas or air component. Where, however, no adsorbent beds are employed, the process gas stream may be passed directly into the compressor side of a turbine compressor-expander to effect a pressurization of the process gas stream prior to its introduction into the expander side of the turbine compressor-expander, thereby enabling the process to handle increased condensing loads.

Title: Fourier spectrometer arrangement and method of operating a fourier spectrometer
Inventor: BAERWALD WOLFGANG
IPC: G01J3/453
Filed: 1992-11-06
Abstract: ABSTRACT OF THE DISCLOSURE           In a Fourier spectrometer arrangement for Fourier transforming an interferogram for determining the optic spectrum of a radiation, the readout of the interferogram is decoupled from particular phase positions of the reference signal through elimination of otherwise required synchronization with an external fixed clock pulse to thereby enable a lowering of the reference frequency and simultaneously to maintain or increase the scan frequency of the interferogram.  The Fourier spectrometer arrangement includes an extrapolation filter which receives the incoming reference signal and employs adaptive state estimation processes in order to generate extrapolation values by which the future course of the reference signal can be projected. These extrapolation values can be calculated at times which are closer together than e.g. zero crossings of the reference signal and may have an arbitrary phase position thereto.  In this manner, the interferogram can be scanned at times which are independent of the phase position of the reference signal and, if necessary, at shorter intervals.

Abstract: An arrangement for discharging hard material from the grinding head (10) of a meat grinder. The hard material is passed through openings (32) formed in the meat grinder orifice plate (18), and collected in a collection cavity (76) defined by a cup member (74). A hard material discharge auger (84) is located within the collection cavity (76), and is rotatable with the feed screw (14) of the grinder. A restricting arrange-ment is provided for building up back pressure within the collection cavity (76), which minimizes   the amount of usable soft material which passes into the collection cavity (76). In one form, the discharge au-ger (84) extends through the collection cavity (76) and into a discharge passage defined by a discharge tube (82).  The auger (84) has an outside diameter only slightly smaller than the diameter of the passage, so that the auger (84) essentially defines a rotating flow path through which the hard material is discharged.
