Abstract: ABSTRACT OF THE DISCLOSURE           A method of intermittently stopping and restarting the laying of pipe offshore from a reel pipelaying vessel having a reel for spooling relatively inflexible pipe thereon, pipe working and handling means for straightening the pipe as it is upspooled from the reel, vessel motive source means for imparting a forward thrust to the vessel, and a reel drive mechanism associated with the reel for imparting at least a dynamic braking force to the reel in an unspooling mode.  The method comprises the steps of:    (a) stopping the forward motion of the vessel in the direction of pipelaying by (1) gradually reducing the forward thrust imparted to the vessel by the vessel motive source, and (2) concurrently gradually increasing the dynamic braking force imparted to the reel by the reel drive mechanism, (3) to cause the reel to decrease its rotational rate toward zero while continuing to unspool pipe and to thereby maintain sufficient tension in the pipeline to hold the pipeline in a desired profile;    (b) locking the reel against further rotation in the direction of unspooling when the vessel has stopped its forward motion;    (c) thereafter controlling the forward thrust of the vessel motive source to maintain the vessel in a station keeping mode and to maintain the pipeline under said sufficient tension to hold the desired pipe profile while the vessel is in said station keeping mode;    (d) performing any necessary operations on the pipe and/or coating while the vessel is in said station keeping mode;     - a -(e) thereafter resuming forward motion of the vessel in the pipelaying direction by (1) disengaging the means locking the reel against the rotation in the unspooling direction, (2) concurrently substantially increasing the dynamic braking force imparted to the reel by the reel drive mechanism such that the dynamic braking force exceeds any increases in the forward thrust of the vessel's motive source at least up to the pipelaying thrust level required to move the vessel in the forward direction at a desired laying speed, (3) gradually increasing the forward thrust imparted to the vessel by the vessel motive source up to said pipelaying thrust level, and (4) thereafter gradually reducing the dynamic braking force of the reel drive mechanism at least until the forward thrust imparted to the vessel by the vessel motive source exceeds the dynamic braking force of the reel drive mechanism and the vessel begins to move forward.          The step of performing necessary operations on the pipe and/or coating may for example comprise the step of applying one or more sacrifical anodes to the pipe at a designated work station located along the pipe path downstream of the straightening means in the unspooling direction.     - b -

Abstract: ABSTRACT CONTINUOUS EXTRUSION OF METALS A continuous extrusion machine in which feedstock is admitted (at 50) to a peripheral groove (12) in a rotating wheel (10), is enclosed in that groove by a cooperating shoe (24), and is frictionally dragged along the arcuate passageway (48) formed by said groove and a protecting portion (30) of said shoe towards an abutment (36) carried by the shoe.  The pressure in the metal in front of the abutment continuously extrudes a metal product through a die (42).  The abutment tip and adjacent wheel parts disposed downstream of the abutment are cooled directly by a jet of cooling fluid issuing from a nozzle (64) carried downstream on the shoe.  An annular band (Figure 2, 74) of a good thermally-conductive metal embedded concentrically in the wheel enhances the cooling obtained.  Flash (68) extruded through clearance gaps (32, 34) between cooperating wheel and shoe surfaces is intercepted and broken off periodically, in short lengths, by teeth 70 projecting from the wheel.  The radial depth of the passageway (48) progressively decreases in the direction of wheel rotation in a zone extending upstream from the abutment (36), so as to improve in that zone, in the case of particulate or comminuted feedstock, the metal flow pattern adjacent the abutment, such feedstock in that zone being in a fully compacted condition without voids. This is achieved by the shaping of a surface (40A) of a die block (40) which adjoins the abutment (36) and incorporates the die member (42).  That shaping produces with particulate or comminuted feedstock a metal flow pattern closely resembling that achievable with feedstock in solid form.  A continuous extrusion product (Fig. 5, 102) issuing from a continuous extrusion apparatus (Fig. 1, 10; Fig. 5, 100) is threaded through a treatment die (104) whereby to change its cross-section, and is continuously drawn therethrough by a tensioning device (106, 112) under the control of a system which (a) senses the temperature of the product (102) as it leaves the extrusion apparatus (100); (b) converts a temperature signal (120) so produced, in a function generator (124), into a tension reference signal (126); (c) compares with that tension reference signal a tension feedback signal (116) derived from a sensor (118) adjacent the extrusion apparatus; and (d) controls the tensioning device in accordance with the difference of the tension reference and feedback signals so as to prevent the sensed tension in the product extending between the extrusion apparatus (100) and the treatment die (104) from exceeding a safe value which is less than the yield stress tension of that product at the sensed temperature.

Abstract: Abstract:     A log bark peeling apparatus comprising nozzles (55) through which high-pressure water is sprayed onto the log. Conveyor means are provided to advance the log in a path (16) through the bark peeling apparatus. The apparatus comprises a first unit (21) which is mounted for rotation about said path, said unit comprising an annular water housing (28) arranged, upon its rotation, to contain a co-rotating ring of water, and a second rotatably mounted unit (22) which supports at least one pitot tube (60). The pitot tube is intended to move with a mouth (61) formed therein foremost in a direction opposite to the rotation of the ring of water and via a channel (48) it communicates with one of the nozzles (55). Upon rotation of the two units in opposite directions water from the ring of water is forced into the mouth (61) of the pitot tube (60) through said channel (48) to be ejected through said nozzle (55) in the form of a jet. The jet is directed against the log (6) which is located in the path and thus in the centre of rotation upon advancement of said log along the path.

Abstract: Abstract The present invention is directed to a fluorescent X-ray method for analyzing a solution specimen.  A parti-cular quantity of the solution specimen to be analyzed is impregnated into a thin porous sheet, for example by a dripping method, and the sheet is dried by evaporating the solvent.  The sheet is placed on an appropriate holder in a vacuum atmosphere or an atmosphere of helium gas, so that primary X-rays are irradiated and the wavelength or the intensity of the fluorescent X-rays generated from the solute remaining in the sheet may be detected.  The strength of the solution may be changed by concentration or by dilution, so that an adequate intensity of the fluorescent X-ray may be generated.  The specimen sampler is made of a porous sheet material, to which the solution specimen to be analyzed is impregnated and dried so that only the solute of the solution remains in the sheet.  To the circumferential edge of the sheet is attached a sup-port, so that the central portion of the porous sheet is sufficiently spaced from the circumferentially provided support.
