Abstract: WOVEN BELTING          Abstract of the Disclosure This invention relates to a woven belting.  The belting has a single-ply central portion, which is preferably woven as a   twill weave.  The belting also has tubular edge portions, which are integrally woven with the central portion, preferably as a   hollow plain weave.  A particularly high abrasion resis-tance can be imparted to the belting if the warp threads for the tubular edge portions are shrunk to such an extent before the weaving operation that the warp threads in the edge portions of the belting become subsequently shrunk to the full extent of their potential shrinkage during the heat setting of the woven belting.  Belting of this type combines most or all of the desirable features that belting intended for safety belts should possess.

Abstract: IN SITU LEACH METHOD FOR          RECOVERING URANIUM AND RELATED VALUES         Abstract of the Disclosure An in situ leaching process for recovering uranium values from a subterranean formation containing calcium-based clays wherein the lixiviant used has a cationic composition essentially the same as that of the formation connate water with only minute quantities of innocuous leaching chemicals, i.e., CO2, and an oxidant, e.g., O2, present therein.  The pH of the lixiviant at the injection well is maintained at a value approximately equal to that of the formation connate water, i.e., 7.5 to 8Ø  The pH control to this level is achieved by addition of limes without introducing additional cations to the leaching circuit.  This lime addition also serves the purpose of calcium removal (water softening) from the lixiviant.  Since there are no cations, e.g., NH4+, added to the lixiviant, there is no problem of contaminating the formation water and altering the nature of the formation, itself, thereby eliminating the need to restore the formation after the leach.  Further, since the lixiviant is essentially of the same cationic composition as the formation water, swelling of clay in the formation is minimized.

Abstract: "METHOD OF AND SYSTEM FOR PRIORITY    TRANSCRIBING OF DICTATION"                          ABSTRACT         A method and system for priority transcribing of a particular unit of dictation in a dictation-transcription system in which units of dictated material may be simultaneously recorded on, and transcribed from, a single continuous recording medium.  The portion of the continuous recording medium from which dictated material has been transcribed is transferred to one of a plurality of bins or to one of a plurality of locations within a single bin from which it is withdrawn to be used for the recording of subsequent dictated material, and the system and method disclosed allows a priority unit of dictation in the sequence of units of dictation recorded on the recording medium to be selected from among other units of dictation in the sequence for transcribing without making any untranscribed unit of dictation in the sequence available for the recording of additional dictation which would obliterate any such untranscribed units of dictation.  The system includes means for forming a zone into which a portion of the recording medium carrying untranscribed dictated material may be placed while a particular unit of the dictation is being transcribed and from which said portion of the recording medium can be withdrawn only for the transcribing of the untranscribed dictated material.  The method includes the steps of moving a portion of the continuous recording medium having dictated material recorded thereon past a transcribing location without transcribing said dictated material and diverting said portion of said recording medium into a retaining zone until a particular priority unit of dictated material is reached at the transcribing location, transcribing the particular priority unit of dictation at the transcribing location while retaining said untranscribed portion in the retaining zone, subsequently returning the untranscribed portion from the retaining zone to a position allowing transcription of said untranscribed portion, and transcribing the dictated material on the previously retained untranscribed portion of the recording medium.

Title: In-mold coating of sheet molding  compound moldings

Filed: 1978-04-24
Granted: 1981-12-22
Abstract: Abstract of the Disclosure Liquid compositions suitable for hot post-mold coating of cured sheet molding compound (SMC) parts com-prise a reaction product of an epoxide and an unsatur-ated carboxylic acid mixed with a low shrink additive. These liquid compositions are used to smooth surfaces, fill porosity and other voids and to eliminate or reduce sink marks.  Coatings typically are cured in less than two minutes and appear able to provide many features of normal painting without paint facilities except possibly those needed for touch-up.         The application method used to date has been to compression mold an SMC part in the usual way, separate the mold halves, inject the liquid composition and re-close the mold for a second cure cycle.  A unique feature of the liquid composition is its ability to ad-here to an uncleaned SMC molding.

Abstract: ABSTRACT OF THE DISCLOSURE A continuous flow stream of combustion products conducted through a chamber, is mixed with moisture-laden ambient air and ignited by discharge from a spark plug connected to the high voltage terminal of a secondary winding in an ignition coil assembly having a primary winding connected between a source of d.c. voltage and a terminal exposed to a gaseous mixture in the chamber.  The high voltage applied to the spark plug is induced by intermittent interruption of the flow of current through the ionized gaseous mixture grounded in the chamber, resulting from restricted inflow of said moisture-laden air into the chamber.

Abstract: ABSTRACT OF THE DISCLOSURE In a top operated tank car valve, a mounting flange is welded to an opening in the bottom of the tank.  A valve seat is located inboard of, and above the lower surface of, the mounting flange.  A vertically extend-ing cage is integrally attached to the mounting flange.  A top operator ex-tends to the top of the tank, and a stem is attached to the lower portion of the top operator.  The stem extends into an opening in a valve closure plug.  A non-round cavity is formed in the bottom of the stem.  The closure plug includes a seat which engages the valve seat located within the mount-ing flange.  The closure plug includes a circular guide ring which engages a portion of the vertically extending cage as the closure plug moves between open and closed positions.  The closure plug includes a vertical, generally central opening which communicates with the circular head portion of the valve stem. A retainer, held in place with retainer fasteners extending from the bottom of the retainer into the closure plug, holds in place a seal located in a circumferential groove in the closure plug.  The retainer includes an extension which extends through the vertical, generally central opening in the closure plug.  The retainer fasteners can be removed from the bottom of the car, providing access to the non-round cavity in the valve stem.  Thus, the closure plug may be opened from the bottom of the tank with a tool extending through the vertical center opening.  Since the valve seat is located within the mounting flange which does not extend more than one (1) inch below the tank bottom, a tank car skid is not needed to comply with AAR regulations concerning projections from the bottom of railway tank cars.
