Title: Removal of impurities formed during the production of 1,3-propanediol
Inventor: BLACKBOURN ROBERT LAWRENCE
IPC: C07C29/88
Filed: 2003-10-30
Abstract: This invention describes improvements upon a process for the production of 1,3-propanediol (PDO) wherein an aqueous solution of 3-hydroxypropanal (HPA) is formed and the HPA is subjected to hydrogenation to produce a crude PDO mixture. One improvement on this process comprises treating the crude PDO mixture with an acidic zeolite, an acid form cation exchange resin, or a soluble acid to convert the MW176 cyclic acetal to more volatile materials which can be easily separated from PDO by distillation. Another improvement involves removing water from the crude 1,3-propanediol mixture, contacting the resulting mixture with a solid acid purifier at a temperature of from about 50 to about 250 °C to convert the MW 132 cyclic acetal to more volatile cyclic acetals, and separating the more volatile cyclic acetals from the 1,3-propanediol by distillation or gas stripping.

Title: Coal liquefication process
Inventor: AMENDOLA S
IPC: C10G1/06
Filed: 1979-06-29
Abstract: Essentially solid carbonaceous material, such as coal (R), is rapidly converted to a high percentage of liquid hydrocarbon products by first reacting said material with an acid (16) to form carbon addition products which then are reacted with a Group V halide ion-acceptor system (super-acid system) (22), the acid content of which is greater than the Group V halide content, and thereafter with a hydrogen donor source (26). All phases of the process may be carried out at atmospheric pressure and relatively low temperatures, thus making said process far more economical than known coal liquefication processes.

Title: Pollution abating,energy conserving glass manufacturing apparatus
Inventor: SENG S
IPC: C03B3/00
Filed: 1980-04-01
Abstract: Apparatus for preconditioning and preheating pellets of glass batch prior to heating and melting them in a furnace. Components of glass batch are mixed together and combined with water to form agglomerates, e.g. pellets. These agglomerates are supplied to a hopper (14) through which hot combustion gases are passed and they are preheated to an elevated temperature in the hopper prior to entering the melting furnace (16), thereby resulting in a savings of substantial amounts of energy. Moisture is removed from the agglomerate prior to their being supplied to the hopper; hence, the tendency for the agglomerates to adhere to one another and form aggregates, or clinkers, is substantially controlled. For that purpose, the agglomerates (120) are collected in a preconditioner (94) having a receptacle (102) located above the bed (28) of agglomerates in the hopper (14) with the hot gases also passing through the agglomerates in the receptacle after passing through the bed (28) in the hopper (14). After moisture is removed, the agglomerates are dropped from the receptacle (102) onto the bed in the hopper. The agglomerates may be melted in a combustion fired melter or in an electrically powered melter.

Title: Dynamic data display system,as for use with eeg
Inventor: DEMETRESCU M
IPC: G06F3/048
Filed: 1981-03-09
Abstract: A dynamic display system for discrete events of complex data that are carried by discrete electrical signals which indicate values in three coordinates as triads. A cathode ray tube display apparatus (16) (television monitor) with a plane surface (20) is actuated by format signals to exhibit a pictorial three-dimensional perspective field of reference somewhat in the figure of an elongate box (22) viewed in perspective. Specifically, as disclosed, the data events or elements are manifest in the form of lines (24) or linear symbols that indicate coordinate values by symbol height and position. The independent variable, time, is scaled from an origin line (40) in the field of reference to extend along the depth of perspective so that the linear symbols advance along the path of perspective to accomplish a dynamic display with the illusion of motion. The specific system herein displays EEG waves, effectively indicating the magnitude and frequency of individual brain waves with respect to time of occurence. Consequently, a marching display is provided revealing fresh information together with a recent history of events in chronological order and in a concise and readily perceivable form. Additionally, recorded data may be later played back affording examination of a past history of EEG. Furthermore, color is utilized in the display to add still another dimension. A conventional television format is employed in which the linear symbols (24) are formed along scanning lines of the television raster pattern.

Title: Deposition techniques for archival recording media for digital data storage
Inventor: LEE NEVILLE
IPC: G11B7/2433
Filed: 1982-11-05
Abstract: Embodiments show a recording medium (10) adapted for recording and read-out with relatively low-power laser means (212) to write digital data "bits" (v) (as reflectance changes) for high density computer storage. One preferred medium comprises a disk support (12) having an "anti-reflective" surface (1-AR) on which is laid a gold "information layer" (15) adapted to absorb recording radiation (from laser beam) (212 a,b,c) and so "write" the bits. The anti-reflective surface (1-AR) may comprise a high-reflectance surface, like an aluminum film, covered with a transparent (to beam) dielectric "spacer" (14) like SiO2. The gold absorber layer (15) exhibits surprisingly high sensitivity, apt for low power recording, and extended archival stability; more surprisingly, it appears to be formed without any evidence of the usual "pit formation" or other deformation and by relatively slight laser heating, well below the melting point.

Patent WO-8600047-A1 (WO)
Inventor: SUMNER EARL COMPTON
IPC: B32B7/08
Filed: 1985-04-22
Abstract: Procédé de jonction de deux matériaux par enclenchement mécanique d'"éclats" (16) à leur surface de contact. Les éclats, composés d'un des deux matériaux devant être joints ou d'un troisième matériau, sont incrustés dans la surface du premier matériau lorsque celui-ci est formé afin de créer des surfaces qui "surplomblent" le premier matériau (134). Le deuxième matériau (12) est ensuite formé contre les surfaces en surplomb des éclats afin de créer l'enclenchement mécanique. Cette technique est particulièrement utile pour fixer un matériau dissemblable à un matériau polymère ayant des propriétés médiocres d'adhésion et/ou une température élevée de fusion, par exemple des fluoropolymères, comme illustré par la formation par moulage rotatif du manchon intérieur d'un carter de pompe. Dans cette illustration, de petites particules et éclats sont uniformément distribués sur la surface d'un moule enfermé, chauffé de sorte à fondre les particules et entraîner l'adhésion des éclats au moule, et refroidi pour former une couche sur laquelle les éclats font saillie afin d'obtenir l'enclenchement lorsque le carter est formé contre le manchon intérieur. D'autres aspects de l'invention comprennent l'article fabriqué selon le procédé ci-dessus.

Title: Mandrel for forming an internal enlargement for a gasket or sealing ring in a pipe or tube
Inventor: LEE ROBERT J
IPC: B29C57/02
Filed: 1986-06-20
Abstract: A mandrel device (10) which guides the end of a pipe or tube (14) to a position outwardly of the path of an expander body (26), with a camming mechanism (36) to force the expander body from an inward position to an outward position, and holding that outward position so as to achieve the desired gasket-receiving enlargement of the tubular work object. In a subsequent stage, another camming feature (46e) forces the expander body radially inwardly, to permit the tubular work object, now carrying the sealing ring (12) in a position which would mean interference by the expander body, to be released over the end of the mandrel. The two camming components are carried by sub-assemblies axially movable with respect to the stationary parts of the mandrel; and they are interrelated to have both movement together and movement with respect to one another, achieving the outward and inward camming effects in a plural-stage motion sequence and nature.

Title: High resolution imaging doppler interferometer
Inventor: ADAMS GENE WYLIE
IPC: G01S13/48
Filed: 1987-05-04
Abstract: A system for simultaneously locating a plurality of targets from noise which utilizes phase detector (164) techniques to generate complex voltage signals and obtain phase information. Spectral analysis (172) is performed on the complex voltage temporal functions to generate doppler frequency functions. Both spectral phase function and spectral amplitude functions are generated from the doppler frequency functions (174). Spectral phase functions are analyzed using interferometry techniques (178) to determine if a potential target has a common locational source from returns of a plurality of sensors. A zenith angle is also generated using interferometry techniques to provide locational information of the multiple targets. Range gating (182) and two-frequency range detection methods provide high resolution range information as to the location of the targets. High resolution range information and two-frequency pulse can be generated simultaneously or sequenced within a pulse in a manner which is phase coherent. The two-frequency pulse eliminates problems associated with range aliasing, zenith angle aliasing, scattering point analysis and allows for range location with high resolution. An error correction factor is also generated which eliminates spectral smearing.

Title: Collapsible gridworks for forming structures by confining fluent materials
Inventor: JOHNSON ROBERT HARLAN JR
IPC: E02D17/20
Filed: 1988-03-11
Abstract: Collapsible gridworks for confining fluent materials within cells defined by the gridworks to form stable columns capable of withstanding substantial vertical and horizontal loading are each made up of a plurality of interwoven/intermeshed longitudinal and latitudinal strips (104, 108). In the preferred embodiment, the strips include slots (106, 110) formed on alternating sides thereof, with the gridworks being formed by interweaving the slots (106) on one side of the longitudinal strips with corresponding slots (110) on the opposite side of the latitudinal strips such that the gridwork is defined by mechanically interlocking joints which permit motion for collapsing the gridwork into both a multilayer strip and a substantially flat sheet. The open state of the gridwork and both of its collapsed states are similarly stable and can be freely handled without fear of the gridwork falling apart. The strips may be extended in width to reinforce and stabilize stacked gridworks, with the widthwise extensions of the strips being slotted for such stacking. The strips may also be extended in length beyond the outermost walls of the gridwork and slotted such that two or more of the gridworks can be interconnected to one another by interweaving the slotted length extensions of the longitudinal and latitudinal strips.
