Abstract: ABSTRACT OF THE DISCLOSURE A Schottky barrier amorphous silicon solar cell incorporating a thin highly doped p-type region of hydrogenated amorphous silicon disposed between a Schottky barrier high work function metal and the intrinsic region of hydrogenated amorphous silicon wherein said high work function metal and said thin highly doped p-type region forms a surface barrier function with the intrinsic amor-phous silicon layer.  The thickness and concentration of p-type dopants in said p-type region are selected so that said p-type region is fully ionized by the Schottky barrier high work function metal.  The thin highly doped p-type region has been found to increase the open circuit voltage and current of the photovoltaic device.

Abstract: DEMULSIFYING PETROLEUM EMULSIONS WITH ARYL SULFONATES-OXYALKYLATED PHENOLFORMALDEHYDE RESINS AND                    ALKALI METAL HALIDES  (D#51,500-TexEx-52-F) Brian W. Allan ABSTRACT OF THE DISCLOSURE         A process for recovering oil from oil-in-water petroleum emulsions stabilized with clay and/or other solids by subjecting them to the action of an optimum amount of non-ionic, water-soluble, aryl sulfonates-oxylakylated phenol formaldehyde resins at a pH of 7.0 to 8.0 and then adding a saturated aqueous alkali metal halide solution to the resulting mixture.  The process is carried out at between about 200°F and 240°F and the mixture is allowed to stand in the quiescent state for a period of about 1 to about 10 hours to allow the halide solution to increase the specific: gravity of the resulting aqueous phase by at least 0.02 thereby causing the bitumen to float and facilitating recovery of the oil.

Abstract: A B S T R A C T        The present invention concerns the use of an aqueous solution of a silicate as a binder, particularly for hardening foundry mold  and cores without the use of acid or other re-agents to convert the silicate into a silica gel.  According to the present invention, the silicate binder is not reacted but instead is rapidly dried, preferably enough within the space of 5 seconds to 10 minutes to reduce the initial water content of the aqueous silicate solution by at least 25%.  In the preferred embodimants, this is achieved by forcing air through opposed porous sides of the mold box and the green sand contained therein.          The present invention is also applicable to other composite forms such as the manufacture of plywood, particle board, briquettes, and the like.

Abstract: Abstract Of The Disclosure A welding machine includes a programming device to move a welding head relative to horizontal main X and Y axes, and to rotate the head about a vertical C axis.  A sensor is connected to rotate with the welding head on a rotator.  A sine cosine resolver is mounted on the rotator so that its shaft is geared to the rotator gear.  Deviations from the programmed path which may occur in the weld groove are sensed by the sensor, which in turn causes the resolver output to drive a slide mechanism which defines deviation axes Xd and Yd and which causes the weld head to move from its programmed path to the desired corrected path, when needed.  The overriding correction is independent of the program.

The tubular component (20) is connected to an introducer cannula (52) that has been placed in a body passageway (65).  Pressurized fluid is forced around and along the catheter (22) in the tubular component (20) to flow the catheter (22) into the body passageway (65).  An enlarged proximal end (29) of the catheter (22) seats in a tapered por-tion (56) of the introducer cannula (52).  The proxi-mal portion (56) of the introducer cannula (52) be-comes the connector for connecting the catheter (22) to an intravenous unit (70).  In a modification, a y component (32) has a needle (60a) in one leg of the Y for insertion into a body passageway (65) so that, after the needle (60a) is withdrawn, the catheter (22) may be flowed by pressurized fluid through the other leg of the y component (32) into the body passageway.  Additional modifications pro-vide for forming the tubular component in a coil form (220) or in a U-shaped form (420).  In all forms of the tubular component (20), the catheter (22) is stored in a configuration wherein no length of catheter (22) contacts any other length of the catheter (22) and the catheter is supported so as not to kink or double over during insertion.

Abstract: ABSTRACT      A synergistic extractant combination consisting of di(2-ethylhexyl) phosphoric acid (D2EHPA) and dibutyl butyl phosphonate (DBBP) in kerosene is employed in a two-cycle separation process for the recovery of uranium from wet-process phosphoric acid.  The addition of the sulfuric acid and water scrubbing steps for the recycled extractant produces no problems to the contamination and dilution by the ammonium ion and water to the phos-phoric acid and also no precipitation occurs in the second cycle extraction step.  The advantages of this process are lower chemical cost, higher product purity and better phase separation in comparison with the previous process.

In use, the tool may be linearly and angularly reciprocally mounted in a power operator, and may be heated for softening the obturating materials, such a gutta-percha.  The reciprocation of the tool, particularly the linear reciprocation, forces the shoulders into compressive contact with the softened material and, when adequate density is attained, backs out of the root canal naturally through reverse action without specific operator effort.  Preferably, the flutes are doubled and continuous and means is provided to rotate the tool at high rpm, oppositely to the direction of the spiral.
