Abstract: LIQUID-COOLED TRANSITION MEMBER AND METHOD OF              MANUFACTURE OF THE TRANSITION MEMBER     Abstract of the Disclosure An improved structure is provided for liquid cooling a transition member which conducts hot motive gases from a combustor to a turbine inlet in a gas turbine power plant. The liquid-cooled structure includes a transition member body having a longitudinal inlet manifold and a longitudinal collection mani-fold attached to opposite sides of the body. The body has a plurality of internal laterally disposed passages which communicate liquid coolant from the inlet manifold, around the body to the collection manifold. The liquid coolant transfers heat from the member in a circumferential flow pattern; then the coolant is discharged from the member by a discharge manifold which is connected to the collection manifold. The method of manufacturing of the transition member provides for forming the body in two mating half subassemblies having internal coolant passages. Each half of the body is blanked from a flat sheet having a shape conforming to the developed shape of the body. Lateral slots are machined on the surface of the sheet. The coolant passages are formed by diffusion bonding a metallic skin over the slotted surface in one method and by embedding tubular members in the slots in an alternate method. The subassemblies are then formed into the contoured shape of the body. The sub-assemblies and components forming the manifolds are welded together to form the transition member.

Abstract: METHOD AND APPARATUS FOR COMPLETING        A SLANTED WELLBORE                 ABSTRACT OF THE INVENTION         A wellbore is formed with the lower marginal end portion thereof being turned substantially horizontally, thereby exposing a relatively large surface area of the pay zone to the cased borehole.  A jet perforating gun has a member extending radially therefrom and into close proximity to the inside peripheral wall surface of the casing, and the shaped charges thereof are oriented so that they fire and perforate in a direction opposed to the arm.  The gun is run downhole into proximity of the pay zone with the shaped charges being directed in a substantially downward direction so that when the gun is fired, the casing is perforated with the perforations extending downwardly into the hydrocarbon bearing formation.  This expedient enables the perforated forma-tion to be produced without flowing any of the unconsolidated formation into the wellbore.

Abstract: ABSTRACT OF THE DISCLOSURE     An optical fiber hydrophone system is described in which a single optical fiber is used for all of the acoustical sensors in the system.  A signal source and detecting means provides an optical signal in selected form, such as continuous or pulsed and detects and extracts an identifiable output signal.  Each sensor is in the form of a sensing portion of the single optical fiber.  Each sensing portion includes two optical reflectors separated one from another by a predetermined length of said optical fiber. Variations in acoustical pressure incident on the sensing portion causes a change in said predetermined length.  This causes reflected portions of the optical signal to interfere with one another.  Such interference is detect-able for extraction of the identifiable output signal.  In one form each sensing portion has two terminal branches of a mechanically deformable material, deformable in response to the fluctuations in acoustical pressure. Preferably, the optical fiber has two portions, a sensing portion thereof underwater and having a first optical cavity, and another portion thereof on board a vessel and having a second optical cavity, typically tunable with respect to the optical length thereof to maximize the interference in the detected optical signal.
