Abstract: ABSTRACT OF THE DISCLOSURE      Multiple wellbores  may  be  extended  from  a  common, generally vertical wellbore and completed for conduction of fluids between said common wellbore and each of said wells by drilling the common wellbore, inserting a seal bore into the common wellbore below the junction  of a deviated well with said common wellbore, inserting a whipstock and then drilling the deviated well.   The  whipstock is removed  and a  guide member is inserted into the common wellbore and secured to the anchor member.  A dual packer is inserted in the common wellbore above  the  junction  of  the  deviated  well  and  is connected to the guide member to provide a flow passage into the wellbore located  below the junction. A second tubing guide connector member is inserted into the common wellbore with a  tubing string extending downwardly  therefrom.   The tubing string is passed through the dual packer and into the deviated well and the second guide member is latched to the dual packer  to provide  dual  flow  paths from each  of  the separate wellbores into the common wellbore or to the surface.          The second guide member includes separate configurations for the respective flow passages to permit  insertion of tubing strings and separate guide heads into the selected wellbores for various well operations.

Abstract: ABSTRACT     A cold weather system for keeping a wearer comfortable in a temperature of about -60°F-+40°F and winds up to 100 miles per hour, utilizes a shirt, pants, parka and wind shirt and wind pants.  A sleeping bag and moisture handling pad/deicing cloth are compressed in compressor bags and easily transported by the wearer for comfort during sleeping too, and used with a bivvy sack having a tent flap.  The shirt and pants are ventable so that they provide comfort over a wide temperature range, the vents being completely closed when maximum thermal protection is desired.  The parka includes a windskirt which engages the wearer's legs.  The wind garments are made of fine denier 100% synthetic material tightly woven so that they have very low air porosity.  The parka and wind shirt can be connected together to provide an emergency bivac sleeping bag   The shirt, pants, and parka include an inner fabric of 100% synthetic material, an inner layer of foam at least 1/8 inch thick, and up to about one inch thick, and an outer shell of low porosity, but high moisture vapor transmission, material.  Portions of the shirt and pants that will be vented also include a fabric covering the insulation, the insulation covering fabric having very high air porosity.

Abstract: SUBSTANTIALLY FLUID-IMPERVIOUS MICROBUBBLED  POLYMERIC WEB EXHIBITING LOW LEVELS OF NOISE        WHEN SUBJECTED TO MOVEMENT                          ABSTRACT A microbubbled, substantially fluid-impervious polymeric web exhibiting substantially the same consumer preferred soft and cloth-like tactile impression and low noise generation levels heretofore only achievable in micro-apertured, and hence substantially fluid pervious, polymeric webs. In a particularly preferred embodiment, the present invention pertains to a microbubbled polymeric web exhibiting a fine-scale pattern of discrete mushroom-shaped surface aberrations, each of said surface aberrations having its amplitude oriented substantially perpendicular to the surface in which the surface aberration originates. However, unlike microapertured webs which are fluid pervious, at least one tiny, continuous membrane bubble, i.e., a microbubble, is provided substantially coincidental with the maximum amplitude of each surface aberration. Thus, the microbubbled web is substantially fluid-impervious. In addition, such a web employing the fine-scale pattern of microbubbled surface aberrations does not exhibit the "rattling" or "rustling" noises typically exhibited by prior art fluid-impervious polymeric webs when subjected to movement. As a result, webs of the present invention have particular utility in environments such as substantially fluid-impervious backsheets for disposable infant diapers and adult incontinent diapers. Preferred method and apparatus for producing microbubbled webs either in "planar" or "macroscopically expanded" form are also disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE          A regenerable cryosorption pump with a movable physical barrier in which the barrier includes a cylindrical body closed at one end and having a circumferential baffle around the open end.  The baffle engages a flange on the hydrogen isotope condensing and pumping surface to require all gases entering the pump during normal operation to pass through the hydrogen isotope condensing and pumping surface, thus avoiding bypass of that surface.  The barrier is advanced by a bellows system to isolate the hydrogen isotope condensing and pumping surface from the sorbent surface during regeneration and thus ensuring separation of hydrogen isotopes such as tritium from helium which is sorbed onto the sorbent surface.

Abstract: ABSTRACT OF THE DISCLOSURE         The  characteristic  ability  of  Streptococcus  faecalis  and inability of Streptococcus lactis to produce the butyrate esterase formed the basis for the development of a differential agar medium to separate these species in pure and mixed cultures.  The differential agar medium contained 0.5% bacto-peptone, 0.3% bacto-yeast extract, 1.0% 2-naphthyl butyrate or 1.0% indoxyl butyrate, 1.5% agar and the remaining 96.7% water (pH 6.5).   S. faecalis colonies grown on naphthyl butyrate agar (24 h; 30°C) produced an intense violet color on immediately after the addition of detector reagents, while S.  lactis did not.   A solid medium with indoxyl butyrate as indicator was found suitable for both qualitative and quantitative  differentiation  by  direct  observation  of  indigo  blue formation around the colonies of S. faecalis.  This is a first rapid new medium developed for separating S. faecalis and S. lactis colonies without inhibition.
