Title: Improvements in or relating to the production of petroleum coke
IPC: C10B55/00
Filed: 1959-09-01
Abstract: A hydrocarbon liquid consisting of a petroleum distillate or a hydrocarbon product derived therefrom by physical treatment and/or chemical reaction is treated with oxygen, e.g. in the form of air, at atmospheric pressure at a temperature of 175-400 DEG C., the oxygen-treated liquid is partially distilled, and the distillate is thermally cracked to produce petroleum coke.  The distillate may be coked in an autoclave for one hour at 500 DEG C.  A shaped mixture of the petroleum coke with the undistilled residue as binder may be successively baked and graphitised.  The baking and graphitising may be repeated one or more times after impregnation with further undistilled residue as densifier.  The undistilled residue may have a softening point of 90 DEG C. and a specific gravity of 1.1 for use as a binder and a softening point of 70 DEG C. and a specific gravity of 1.08 for use as a densifier.  Specification 862,221 also is referred to.

Title: Gas analysis
IPC: G01N27/18
Filed: 1965-07-14
Abstract: 1,071,896. Analysing gases electrically. SOLVAY et CIE. July 14, 1965 [July 17, 1964], No.29818/65. Heading G1N. To measure continuously the percentage of hydrogen in chlorine produced by electrolysis of brine, the gas is led through a bubbler 1, a first thermal conductivity measuring cell 2, a reaction tube 3, where ultraviolet radiation causes interaction of the hydrogen and chlorine, and a second thermal conductivity measuring cell 4. The measuring cells 2, 4 contain respective resistance thermometers 21, 41 connected in a Wheatstone bridge circuit having a millivoltmeter 12 graduated in percent hydrogen and operating an automatic recorder. A predetermined unbalance in the bridge may activate an alarm. A plurality of analysers may analyse the respective outputs of a plurality of electrolysis cells. The bubblers 1 (which cool and clean the gas and provide a rough indication of the flow rate) are irrigated with cold chlorine saturated water which is circulated through a common system comprising a reservoir 6, pump 7, filter 8 and refrigerator 9. Cleaning of the analysers is effected by closing valve 11 to direct water from the bubblers through the measuring cells and reaction tubes, the water returning to the reservoir 6 via pump 5 which is conveniently a water ejection pump.
Patent GB-848811-A (GB)
Title: Yarns and coated fabrics
IPC: D01F6/62
Filed: 1956-10-01
Abstract: A travelling bundle of filaments of polyethylene terephthalate is stretched in a continuous manner at a temperature between 325 DEG  F and 450 DEG  F but the bundle is not thereafter heat-set by holding it for an appreciable time, under a tension sufficient to prevent it from shrinking, at a temperature equal to or higher than the temperature at which it was stretched.  The thus treated yarn has a tenacity of 7-9 grams per denier both before and after shrinkage, and if maintained at a temperature between 230 DEG  and 275 DEG  F while being allowed to shrink freely for a period sufficient to ensure that substantially no further shrinkage occurs, and then allowed to cool to normal room temperature, has an elongation at break of not over 12% and a shrinkage of not more than 4% when reheated and maintained at 230 DEG  F for 4 hours and a shrinkage of not more than 6,25% when reheated and maintained at 275 DEG  F for 4 hours.  A high tenacity polyethylene terephthalate yarn sold under the Registered Trade Mark "Dacron" may be hot-stretched 15% or more at a temperature within the range 325 DEG  F to just below the melting point of the polymer.  It has been found that, if the treated yarn is subjected to a "heat setting" step, this step no longer effects a decrease in the shrinkage of the yarn when maintained at 250 DEG  F.  Yarns such as "Dacron 5100" are preferably hot stretched 20% and yarns of initially lower tenacity, such as "Dacron 5500," are preferably stretched to a greater degree.  In an example, zero twist 50-filament "Dacron 5100" yarn having a tenacity of 6,6 grams per denier and an elongation at break of about 8,4% is stretched 18% at about 400 DEG  F, but without heat-setting.  The tenacity of the yarn is thereby increased to about 9 grams per denier and its elongation at break is reduced to about 7%.  After being maintained at 248 DEG  F for 1 hour at no load the tenacity of the yarn is only reduced to 8,3 grams per denier and its percentage elongation at break is only increased to 11,0%.  The stretching of the yarns may be effected by passing them from a bank of feed rolls through an oven maintained at the prescribed temperature to a bank of draw rolls driven at a higher peripheral speed.  Instead of an oven, a hot-plate maintained at an appropriate temperature may be used. A few turns, preferably two turns, of Z-twist per inch are preferably imparted to the yarn before the hot stretch treatment to improve the weavability of the yarn.  Yarns treated as described above may be used to weave fabrics which are then coated in turn with methylene diisocyanate and chlorosulphonated polyethylene (see Group VIII).  Specifications 603,840 and 679,619 are referred to.

Title: A new or improved method of and apparatus for securing a metal support to an articleof fused silica
IPC: H01K1/46
Filed: 1930-10-07
Abstract: 364,188. Mercury vapour l a m p s . BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Buttolph, L. J. ; 1, Columbia Avenue, Grantwood, New Jersey, U.S.A.) Oct. 7, 1930, No. 30014. Convention date, Oct. 7, 1929. [Class 39 (i).] A method of attaching a metal ring, ferrule, or annular support to a hollow article of fused silica, particularly to the envelope of a mercury vapour arc lamp, consists in forming the ring of metal having a relatively high coefficient of expansion as compared with that of silica, heating part of the silica article until it is plastic, and then inserting it in the metal ring and expanding it by internal pressure into contact with the ring. The silica does not contract much on cooling, but the contraction of the metal ring is considerable and it grips the article firmly when cold. A machine for attaching rings to silica arc lamp envelopes is shown in Fig. 1 and comprises a bedplate 1, a fixed headstock 2, and a sliding headstock 3 which can be moved by a hand-wheel 9. The head 2 supports a rotatable chuck 4, while the head 3 supports a mould 5 which is coaxial and rotates in unison with the chuck. A hand-lever 10 opens the chuck, and a hose 11 connects the hollow spindle of the chuck to a source of compressed air. Gas blowpipes 12 are mounted in a slidable carriage which can be moved along the bed by a handwheel 13. The mould 5, Fig. 2, is preferably formed of graphite and is provided with a recess 15 to hold a metal ring. In use, a metal ring 16, Fig. 4, is inserted in the recess 15 in the mould, and a tube 17, Fig. 1, of fused silica, having one end closed, is placed in the chuck 4. The chuck and the mould are rotated, and part of the silica tube 17 is heated by flames from the blowpipes 12. When the silica is sufficiently soft, the mould 5 is applied to the tube by means of the hand-wheel 9, and air under pressure is admitted through the hose 11 to the interior of the tube to expand the softened part into contact with the mould. The metal ring 16 is also heated by the silica and expands, so that its subsequent contraction on cooling causes it to grip the silica tube. The mould may be so shaped that the metal ring rests in a depression in the silica tube, as shown in Fig. 4. In other cases, where a depression is inadmissible, holes are formed in the metal ring and the softened silica is forced into these holes to engage the ring and lock it in place. When the silica tube forms part of a mercury arc lamp, a tubular guard is slipped over the end of the lamp and secured to the ring 16 by screwing or by the use of silver solder.

Abstract: 636,774. Blind riveting. BRITISH UNITED SHOE MACHINERY CO., Ltd., and COOPER, B. P. Nov. 15, 1947, No. 30406. [Class 43] In a hand or poweroperated tool for blind riveting, the mandrel having a shouldered pulling part with which the pulling portion of a member in said tool co-operates to pull the mandrel and thus set the rivet, said member has a slot into which the mandrel stem is introduced transversely of the direction of pull so that the pulling portion of said member lies between the shoulder of the mandrel and the. work, the abutment means which hold the rivet up to the work during setting comprising a number of jaws, the abutment faces of which together normally form a continuous surface for engaging the rivet all round the mandrel, but which are separable to allow transverse introduction of the mandrel stem therebetween. The tool includes a sleeve 13, which is pulled down vertically in its casing 11 by operating lazy tongs mechanism of the type shown in Specification 348,818, the pulling portion 45 of the sleeve lying at one end of an axial bore 43 in the latter, and being provided with a radial slot 47. Opposed jaws 49, pivoted at 53 to the casing 11, have integral depending arms 57, the ends of which enter opposed slots 59 in the casing 11 to be acted on by leaf springs 61. By extending the lazy tongs mechanism fully the sleeve 13 pushes apart the jaws 49 against the action of the springs 61 to allow introduction into the tool of an assembly comprising a headed rivet 35 threaded on the stem of a headed mandrel, the projecting stem part 37 of which terminates in a shouldered pulling part or head 39. The stem part 37 of the mandrel is passed horizontally through the slot 47 in the sleeve 13 until the lower head 39 of the mandrel lies in the bore 43 below the pulling portion 45 of the sleeve 13, and the upper end of the stem part 37 lies centrally between the jaws 49 ; by slightly pushing in the operating knob of the mechanism the jaws 49 engage one another under the action of the springs 61, the stem of the mandrel being accommodated in central'semi-circular recesses in the abutment faces 65 of the jaws, these faces now forming a continuous surface engaging the rivet all round the mandrel stem. In use, the rivet, supported by the faces 65, is held against the work by manual pressure on the casing. 11, and the lazy tongs mechanism is operated so that the pulling portion 45 of the sleeve 13 pulls down the shouldered part 39 of the mandrel to effect setting, the jaws 49 being urged more tightly together as setting proceeds since the pivot pins 53 are off-set from the line of action of the pull.
