Abstract: An acceleration nozzle for particles entrained in a carrier gas comprises a first central nozzle having a first diverging cross-section, and an extension nozzle section extending from the first nozzle. The extension nozzle section has a flare or diverging angle which is greater than that of the first acceleration nozzle. The nozzle extension is surrounded about its mouth or opening by a second nozzle forming a casing or housing therearound; the second nozzle being connected to a source of gas. In a preferred embodiment, instead of utilizing two distinct gas sources to supply the first acceleration nozzle and the second "housing" nozzle, a portion of the gas passing through the acceleration nozzle may be diverted by means of slits built into the latter. The slits act as a separator of the gaseous phases and solid particles, and prevent the solid particles from penetrating the second nozzle. Acceleration nozzles of the present invention are typically used for delivering carboniferous powdered materials into a steel bath.

Abstract: Epoxy resins containing both terminal hydroxyl groups and epoxy-derived groups are prepared by advancing a polyepoxide with a polyol and terminating the reaction at a point such that the epoxy resin reaction product contains both epoxy and terminal hydroxyl groups. The epoxy groups are then further reacted to form epoxy-derived groups and the rate of curing is further improved. The resulting epoxy resins exhibit lower melt and solution viscosities than those exhibited by conventional epoxy resins having the same epoxy equivalent weight, as well as curing quickly when used. The resins are usefully employed at high solids levels in can coating formulations and other epoxy formulations wherein the resin is applied from an organic liquid solution or aqueous dispersion.

Granted: 1994-09-06
Abstract: A paper forming apparatus has a lower looped forming wire disposed for a portion of its travel over a curved apron board.  The paths of forming wire travel upstream and downstream of the apron board diverge.  Such divergence allows a secondary headbox to be brought into such a juxtaposition with the forming wire coming off the apron board as to permit the stock stream to impinge the forming wire both at a low angle and at a short distance to enhance formation of an additional web ply over  a previously formed web ply. In one embodiment, an upper looped forming wire is brought into co-running engagement with the lower forming wire over the downwardly extending downstream path of travel.  In two-wire embodiments, the turning roll for the upstream end of the upper forming wire is downstream of both the headbox slice and apron board to permit the headbox slice to be positioned close to the lower forming wire and allow the stock stream to be projected downwardly to impinge the lower forming wire at a small angle or a short distance from the slice, or both.

Abstract: A process for eluting a gold-iodine complex from a strongly basic anion-exchange resin on which the complex is  adsorbed  is  described.    The  process  involves recovering a gold-iodine complex by adsorption with a strongly basic anion-exchange resin from a wash solution containing a  low concentration of gold-iodine  complex that results from iodine-aided leaching of gold from a gold-containing  material,  and  thereafter  eluting  the complex from the resin.   This method is useful for the washing system associated with a lixivial process using an iodine/iodide lixiviant, such as in situ, heap, vat, or agitated leaching.

Title: Wideband expander for stereo and sap signals
Inventor: ANDERSON MARK R
IPC: H03G7/06
Filed: 1991-01-17
Granted: 1994-02-15
Abstract: ABSTRACT A decoding arrangement for decoding audio signals previously encoded in accordance with the dbx format, includes a wideband expander instead of a full dbx expander.  The wideband expander employs a relatively simple, and therefore inexpensive, peak detector in place of the true RMS detector of a full dbx expander, and does not include apparatus for spectral expansion of the audio signal.  Although the decoding is noncomplementary with respect to the encoding, the stereo audio reproduction as perceived by a listener, is surprisingly good.

Title: Tape cassette
Inventor: TANAKA MASATO
IPC: G11B23/28
Filed: 1991-09-18
Granted: 2000-01-18
Abstract: A tape cassette includes one or more manually settable slider elements that are detected to prevent erroneously erasing information recorded on the cassette.      The element slides in a through hole in the cassette case and includes stop surfaces that limit the travel of the slider element by cooperating with protrusions or shoulders that are formed by the respective half cases making up the cassette case. The slider element also includes a click-stop protrusion that cooperates with a protrusion in the through hole that is formed in only one of the two half-cases.       The slider element further includes a through slot that permits deformation of the slider element as the click-stop protrusion goes over the protrusion in the through-hole, thereby requiring less force to move the element. The stop surfaces can be formed by two spaced apart protrusions that also permit deformation of the slide element as the click-stop protrusion travels past the protrusion in the through-hole.
