Abstract: BEHIND CASING FLUID FLOW DETECTION   IN PRODUCING WELLS USING GAS LIFT          (D#74,517-3-F) ABSTRACT OF THE DISCLOSURE      Methods are provided for locating and measuring the linear flow velocity and volume flow rate of undesired water production behind casing in a producing well operating on gas lift while the well remains in a producing configura-tion.  A well logging tool sized and adapted for passing through production tubing is lowered through the tubing string into the producing zone.  The tool contains a source of 14 MEV neutrons and two longitudinally spaced gamma ray detectors.  The detector may be placed alternately above or below the neutron source on the tool while maintaining the same source to detector spacing.  With the well on produc-tion under gas lift the earth formations behind the casing are irradiated with 14 MEV neutrons, either continuously or in bursts, to activate elemental oxygen nuclei comprising the molecular structure of the undesired water flow.  The decay of unstable isotope nitrogen 16 produced thereby is detected by the detection of its characteristic gamma rays at the dual  spaced detectors.   These measurements may then be interpreted in terms of the linear flow rate and volume flow rate of the undesired water flow.                             -I-

Abstract: ABSTRACT OF THE DISCLOSURE     A universal digging boom assembly is disclosed for attaching either a conventional type digging chain or a rock type digging chain for trenching operations.  The boom assembly includes a box-like core section having upper and lower stiffening strips wherein each stiffening strip includes a plurality of embossments along its longitudinal extent.  These embossments form mounting portions between the stiffening strips and the core section so that sprocket assemblies or channels may be attached to the boom assembly depending on the type of digging chain being used.  The digging boom also includes an attachment portion which permits the boom to be mounted on the trencher for both center and offset trenching operations.          Other features include the sprocket assemblies and a rock chain channel which provide additional ease in the utilization of the various types of digging chains on the boom assembly.

Abstract: Abstract of the Disclosure The present invention relates to the sphere of electronic retouching technology and provides a method of and a circuit arrangement for partial elec-tronic retouching in colour picture reproduction.   The colour values of the individual colour components, which are obtained by image-dot-by-image dot and trichromatic colour picture scanning, are stored in a storage medium.  A colour increment unaffected by location, which in each case represents the minimum modificatory quantity for the colour values, in deter-mined for each colour component which is to be retouched. A location-dependent retouching factor which indicates the retouching intensity as the number of the colour increments which are to be added or subtracted per image dot, is determined for each image dot which is to be retouched, which is marked by the operator by means of a co-ordinate stylus. Location-dependent corrective values are calculated image-dot-by-image dot for the stored colour values, from the colour increments and the retouching factors.  The unretouched or retouched colour picture is illustrated on a colour monitor for the purpose of visual checking.

Abstract: ABSTRACT OF THE INVENTION            Surgical needles are attached to sutures with controlled pull-out characteristics by a short crimp - that is a crimp whose length is markedly less than the length of the end of the suture in the needle; with an essentially undistorted portion of the needle adjacent to where the suture emerges from the needle, and an essentially undistorted portion around the front of the suture, so that only a short section of the needle is crimped around the suture.  The application relates to a two-piece symmetrical swaging die for swaging the crimp in the needle.  The die has a land with a radius slightly less than the needle radius, a width along the axis of the needle less than about half the blind hole depth, and a slight enlargement at the end of the land radius near the die face.          The enlargement permits metal displacement.

The nozzle valve device employs a design in which a nozzle throat blockage element can be moved by translational motion into and out of the nozzle throat section of the de-vice.  The blockage element is designed so that in the closed position the nozzle throat has a minimum cross-sectional flow area and therefore the nozzle throat is never fully closed. The seals employed in the nozzle/valve device are isolated from contact with reaction products of the gas generator and effective use of minimum amounts of erosion resistant mate-rials is achieved.

Abstract: ABSTRACT OF THE DISCLOSURE            The present invention relates to a process for pro-ducing moulded parts from flat tangled fibre fleece mats, preferably formed from binder-containing cellu-lose or lignocellulose fibres in which the fibre mat is compressed by press tools and is subsequently op-tionally provided with a decorative surface layer. The compression takes place in two stages of pre-moulding and final moulding in successive strokes in a single press without intermediate cooling and the decorative surface layer is supplied to the press after final moulding. Between the press tools which are in the open position for the first process stage is introduced a premoulding tool used for premould-ing the fibre mat, for the decorative process stage following the final moulding in the open press tool an auxiliary tool is introduced which, with regards to the compression moulding pressure, temperature, shaping and/or surface strucutre, can be matched to the characteristics of the decorative surface. The apparatus for performing the process is an auxiliary and premoulding tool which can be inserted and removed by guides and permits a vertical adjust-ment.

Abstract: ABSTRACT         A calender roll whose shell consists of ferromagnetic material is heated by several groups of electromagnets which are mounted within the shell on a stationary carrier and whose pole shoes are adjacent to the internal surface of the shell.  The temperature of the external surface of the shell is monitored at several locations as considered in the axial direction of the roll, and the resulting signals are compared with reference signals denoting the optimum or desired temperatures at such locations.  Signals denoting the differences between the actual temperature signals and desired temperature signals are used to regulate the characteristics of electric current which is supplied to the windings of the electromagnets.  Each electromagnets of each group can be regulated independently of all other electromagnets.  Alternatively, two or more electromagnets of each group or entire groups of electromagnets may be regulated simultaneously.  Additional electromagnets are provided to heat the end portions of the shell. Alternatively, such end portions can be heated by the rotors of electric motors which rotate the shell.  The characteristics of current which is supplied to the windings of certain electromagnets can be influenced by signals which denote the magnitude of flexural stresses upon selected portions of the shell so that the corresponding electromagnets oppose deformation of adjacent portions of the shell.
