Title: Improved manufacture of organo-siloxanes
IPC: C07F7/08
Filed: 1944-04-25
Abstract: Thermally stable liquids suitable for use as filling medium for transformers, circuit-breakers, submarine cables, condensers and for use as lubricants or fluids in hydraulic pressure systems; or which may be further polymerized to give viscous liquids or thermoplastic solids, are obtained by hydrolysing mixtures containing a silane of the formula R, R1, R11SiX with a second silane having formula R, R1, SiX2 or R, R1, R11SiX, where R, R1, R11 are the same or different saturated monovalent hydrocarbon radicals and X is either an alkoxy or a halogen radical and where both the silicanes have the formula R, R1, R11SiX, one or more of the radicals R, R1, R11 are different in the respective silicanes, followed by dehydration so as to obtain intercondensed silicones.  The intercondensation is performed by introducing the silicane mixture preferably dissolved in a common solvent, e.g. alcohol, dioxane, acetic acid, acetone drop by drop to the necessary amount of water, dioxane being preferred where halides only are present.  A trace of acid (hydrochloric) may be added as catalyst.  The intercondensates are soluble in benzene and toluene and may be completely dehydrated by heating.  In examples: (1) equimolecular parts of (C6H5)(CH3)2SiCl and (CH3)2Si(CO2H5)2 were mixed and added drop-wise to water diluted with 4 volumes of alcohol. On evaporation, a mobile liquid suitable for use as a transformer oil was obtained.

Title: Improved coking processes for converting heavy oils
IPC: C10G9/32
Filed: 1955-03-18
Abstract: In a process of cracking heavy oils such as petroleum distillation residua by contact with mobile heat-carrying particulate solids, a small quantity of finely divided solids is added to the oil feed or to the cracking-vessel in order to check the tendency of the coated particles to agglomerate.  A fluidized bed system comprises a coking vessel 11 with superposed sections 15, 17, 19, 23, surmounted by a scrubber 71 and fractionator 73, a burner vessel 13 for reheating the solid particles being connected therewith by pipes 31, 43 provided respectively with aerating taps t1 ... t4 and t5 .. t7 for propelling the particles to and from the retort.  Oil is fed through a line 61 to spray nozzles 63, 65, preferably at various levels in the bed. Vapours separated from fine solids returned through a <PICT:0765832/III/1> dip leg 69 pass to the scrubber 71 and thence through the fractionator 73 to an outlet 75.  Fractionator bottoms may be pumped to the top, used as scrubber liquid or withdrawn through a line 83.  Scrubber bottoms containing very fine solids may be recycled by line 85 or diverted through a line 87 together with some of the oil feed if desired admitted through a branch 89, and returned to the bottom of the bed.  One source of fine solids to be mixed with the feed comprises product coke which, after being stripped by steam &c. admitted through an inlet 101 is withdrawn through a line 37 and propelled by steam &c. injected through inlets t8 ... t11 into a riser 111 and thence through a grinder 113 to a hopper 115 supplying the oil feed line.  An oil, vapour, or steam jet 119 and a mixer 91 may be used for thoroughly dispersing the solids. Another source of fine solids is obtained from the cyclone 131 in the burner vessel by diversion through a line 139 to the grinder or hopper 115.  The amount of solids combined with the feed preferably ranges between .25 and 7 per cent by weight and may be the same material as the heat-carrying particles or different: coke is usually preferred to carborundum, glass, alumina or metal.  A stream of particles such as "transfer line" dispersion may replace the fluidized bed. The coking temperature is preferably 850 DEG -1200 DEG F.  The fines may be introduced dry into the coking vessel.

Title: Improvements relating to electromagnetic apparatus for use in the examination of ferrous articles
IPC: G01N27/90
Filed: 1943-05-20
Abstract: 564,451. Magnetic tests and measurements. MORRIS MOTORS, Ltd., BROWN, R. J., and BRIDLE, J. H. May 20, 1943, No. 8049. [Class 37] Ferrous articles are compared as regards composition, hardness, presence of flaws, or other conditions affecting their magnetic qualities by means of electromagnetic apparatus. The sample work-piece f to be tested, such as an iron or steel stud or screw, is inserted into a pair of air-cored windings consisting of a primary winding a and a secondary winding b spaced apart. The pattern c with which it is to be compared is inserted into a similar pair of windings comprising a primary winding a<1> and a secondary winding b<1>, its position being determined by a stop d. One end of the sample f abuts against a slidable stop e which is formed on or secured to a rack g engaging a pinion h. This carries a pointer i moving over a scale k. A spring l presses the stop e into contact with the sample f. The range of movement of the stop e is such that the sample can be moved towards and beyond a mean position corresponding to the position of the pattern c. A projection m closes either of a pair of switches n at its limits of movement, the switches controlling lamps or other signalling means. The two primary windings a, a<1> are connected in series and supplied with alternating current. The secondary windings b, b<1> are connected in series opposition. In order to determine when the E.M.F.'s generated in the secondary windings are in a state of balance, a cathode-ray tuning indicator is connected to the secondary windings b, b<1> through an amplifier. The sample f is pushed inwards until a state of balance is indicated on the cathode-ray indicator, the position of the pointer i then being noted.

Abstract: 1499011 Forming sealing elements W GOULD and C GOULD 26 Feb 1975 [8 March 1974] 8064/75 Heading B5A [Also in Division F2]  Tubular elements, e.g. sealing elements 10 and 11 are formed by a controlled sequence of operations in which a reel of cold-flow polymeric resin tubular stock 18 is withdrawn by feed wheels 19 and 20 and is fed along a linear path between a pair of clamp members 26 and 27 and thence through a circular forwardly tapering guide opening 28 in plate 29. The clamp member 26 is stationary while the clamp 37 is actuated by rod 30 in and out of stock clamping engagement with clamp 26. Axially aligned with the guide opening is a rolling tool 53 which can also be reciprocated along its axis. The driving mechanism is arranged so that at the start of the cycle the tube is aligned with the end of the plate 29 after the seal has been formed and cut by cutter blade 34. In sequence clamp 27 is retracted permitting the advance of the stock into engagement with the tool 53. Clamp 27 then closes to lock the tubular stock against axial movement. The rotating tool 53 is then advanced so as to roll the end of the tube until the edge of the stock reaches the guide plate 29. Clamp 27 and tool 53 are retracted and the stock follows the tool until the desired length of seal is reached. Clamp 27 locks the stock again and the tool is fully retracted. Following the full retraction of the tool the disc cutter 34 moves across the tubular stock and severs the finished element 11. The cycle is then repeated.

Title: Production of hydrogen enriched with deuterium and of heavy water
IPC: C01B5/02
Filed: 1960-03-09
Abstract: In the production of heavy water, NH3 is enriched in deuterium by exchange with H2, the NH3 is decomposed, N2 is liquefied and separated from the resulting gas and evaporated, the remaining D-enriched H2 is cooled and rectified, <PICT:0903367/III/1> and heavy water is produced from the enriched H2 by oxidation and rectification.  N2+H2 synthesis gas enters, and is withdrawn from exchange column 3 at 1, 2 and H2 flows in a closed cycle 9 through cold and hot exchange columns 7, 8, in countercurrent to liquid ammonia containing catalyst flowing from 5 to pipe 4.  Enriched NH3 is withdrawn at 14 from evaporator 13 to cracking plant 15, where NH3 is decomposed at 900 to 1,000 DEG  C. in the presence of a nickel and iron oxide catalyst to produce a mixture of N2, H2, and HD.  The gas mixture passes through heat-exchangers 17, 18 where N2 is liquefied and allowed to separate, and, after evaporation, by return countercurrent to the entering gas, is passed to NH3 synthesis plant 6.  Remaining gas passes through heat-exchanger 19 to rectifying column 20, whence the D-impoverished fraction of H2 is withdrawn at the head and is circulated, from 21, countercurrent to the gas in heat-exchangers 17, 18, 19, and to a portion of the circulating gas, withdrawn through compressor 24, in heat-exchangers 25, 27. The withdrawn compressed portion passes through 25, 27, and expansion turbines 26, 28 to condenser-evaporator 29 of column 20, and condensed liquid is sprayed into the head of the column. Circulating H2 is also withdrawn through 22 to the NH3 synthesis 6, or to the feed to the exchange column 3.  The enirched H2 passes through 33 to combustion chamber 34, whence the vapour mixture passes to rectification column 36 for recovery of heavy water at 40.  The D-impoverished fraction is electrolysed at 11 and H2 is returned at 10 to the cycle through columns 7, 8.  Alternatively, the H2 from the NH3 decomposition may be heated to split H-D bonds and recombine D by the equation <FORM:0903367/III/1> by passage over a nickelchromium catalyst.  The D2 is separated by rectification and oxidized.
