Title: Depressed cladding optical fiber cable
Inventor: GARTSIDE CHARLES H III
IPC: G02B6/036

Granted: 1992-01-07
Abstract: DEPRESSED CLADDING OPTICAL FIBER CABLE Abstract An optical fiber cable includes a core comprising plurality of units Each unit is formed by a plurality of optical fibers which are assembled together without intended stranding. Each of the optical fibers includes a core, and inner and outer claddings with the inner cladding characterized by an index of refraction depressed from that of the outer cladding The ratio of the inner cladding diameter to the core diameter and the ratio of the difference in the indices of refraction of the inner and outer claddings to the difference in indices of refraction between the core and the inner cladding are such that each optical fiber is capable of operation in a single mode fashion at a predetermined wavelength. Also, the difference between the indices of refraction of the core and the inner cladding is sufficiently high to cause eachfiber to be substantially insensitive to microbending. The plurality of units are enclosed in a common tube which provides a predetermined packing density. In one embodiment, a waterblocking material is disposed within the tube to fill the interstices between the optical fibers and between the units. The waterblocking material is such that its critical yield stress does not exceed about 70 Pa at 20°C and such that it has a shear modulus of less than about 13 KPa at 20°C. The common tube is enclosed with a sheath system. This arrangement is such that the optical performance of the cable is not degraded at temperatures as low as -40°F.

Abstract: ABSTRACT OF THE DISCLOSURE          The invention relates to a method of manufacturing a surface material made from different materials.  A heat-resistant mold having its inner surface corresponding to the product to be produced, and a second mold to contain materials, are put together to form a molding chamber inside; and the materials of powder, paste of liquid thermoplastic resin materials are then placed in the molding chamber.  In heating the chamber to form the surface materials, a partition is formed to divide the overall mold into a plurality of molding chambers leaving  a certain gap against the inner surface of the mold.          A groove is provided on the upper end of the partition and a small projection corresponding to the groove is made on the inner surface of the upper mold wall.  Different kinds of resin materials are placed in the plurality of chambers and a resin body is placed in the groove of the partition.  The upper mold and the material-containing mold are put together with the projection inserted into the resin body to form the surface materials in the molding chambers simultaneously; and the surface materials in the adjacent chambers are bonded together by the melting resin in the groove.

Abstract: Abstract of The DisclosurE A system and method for cleaning contaminants from shed blood to enable reinfusion of a cell concentrate in the patient employs successive rotary membrane filtering stages in which Taylor vortices are generated.  Shed blood led into the first rotary membrane stage is filtered to a hematocrit in the range of 50-60 with some of the waste matter being removed.  The intermediate cell concentrate is passed to the second filter stage where further waste matter is initially extracted.   At any intermediate region, however, a major amount of wash solution is fed into the concentrate and effectively mixed by the Taylor vortices.  In the remaining length of the second filter stage waste matter is entrained in wash solution and both waste and wash solution are filtered out to provide a cell concentrate from which the great majority of contaminants have been removed.

Abstract: ABSTRACT OF THE DISCLOSURE A modular connector for interconnecting a coilable tubing string with a downhole electrical tool and wherein an electric signal conducting cable extends through the tubing string and through the connector. The connector includes a swivel coupling having a coupling body with a spherical socket for receiving a spherical coupling member which is connectable to the downhole tool through a cable connector body secured to the spherical coupling member. A pin disposed in the coupling body projects into a slot in the spherical coupling member to prevent rotation of the tool with respect to the longitudinal central axes of the connector and the tool. The connector includes a frangible coupling for retrieving the tubing string if the downhole tool becomes stuck. Separation of the frangible coupling exposes a fishing head for retrieving the tool. A one-way check valve in the connector body permits injection of fluid into the wellbore through the tubing string while precluding wellbore fluids from flowing in the opposite direction up through the tubing string. The connector body is adapted to be connected directly to the downhole tool if the swivel coupling is not required.

Granted: 1992-08-04
Abstract: PROCESS FOR PRODUCING ELEMENTAL SULPHUR                   A B S T R A C T    The present invention relates to the production of elemental sulphur from sulphur dioxide and hydrogen sulphide by the Claus reaction.   To obtain elemental sulphur, into a catalyst bed di-vided into at least two parts the reaction gas having tem-perature of not less than 120°C is introduced in the direc-tion perpendicular to the cross-section along which the catalyst bed is divided. At least into one part of the catalyst bed sulphur dioxide and hydrogen sulphide are introduced at a temperature below the dew point of sulphur. Between parts of the catalyst bed resulting from its divi-sion intermixing and/or cooling of the reaction gas is effected. In at least one part of the catalyst bed the direction of supply of the reaction gas is effected to the opposite when the difference in temperatures of this gas at the inlet and outlet of the catalyst bed reaches 50-150°C. Gaseous sulphur formed as a result of interaction of the reaction gas with the catalyst is withdrawn from the catalyst bed and subjected to a further condensation.

Title: Data format conversion circuit
Inventor: YOUNG JOHN S
IPC: H04Q11/04
Filed: 1988-04-28
Granted: 1992-10-27
Abstract: DATA FORMAT CONVERSION CIRCUIT   ABSTRACT OF THE INVENTION This circuit converts data in an ISDN data format to data in a T-carrier compatible data format and vice versa.  The converted data is then stored in a memory for subsequent transmission.  Due to the format differences, the data may be discontinuous.  This circuit stores the data in memory in a contiguous fashion to promote and to facilitate the subsequent transmission of the data.  This circuit includes a timing and control arrangement which indicates the size of each channel and frame of input data.  This circuit generates memory addresses for the storage of both ISDN and T-carrier formatted data which are contiguous over multiple frames of data.  A counting arrangement of this circuit converts data received in a module 32 format to stored data in a module 24 format or vice versa.  In addition, this circuit provides output signals for generating proper framing bits and extended superframing information.

Abstract: Abstract of the Disclosure Methods for forming or purifying organometallic compounds of elements of Group III-A of the Periodic Table.  An intermediate compound is formed which is an adduct of the desired organometallic compound and a Group I-A or Group II-A compound.  The adduct is nonvolatile, so volatile impurities are removed from the adduct by distillation. The adduct is decomposed to release the volatile organometallic compound, which is then distilled away from the nonvolatile remainder of the adduct.  The method can be used to produce organo-metallic compounds which are substantially free of volatile metallic compounds and complexed solvents.   A method of separating volatile Group II-B impurities from volatile Group III-A compounds is also disclosed.
