Title: Tool joint wear protectors
IPC: F16L15/00
Filed: 1976-03-17
Abstract: 1496641 Drill pipe tool joints CHRISTENSEN INC 17 March 1976 [21 July 1975] 10654/76 Heading E1F A well drill pipe tool joint has an array of discrete areas of hardfacing material distributed non-uniformly over an axially-extended region thereof. Spaced from the free end of the joint, the areas of hardfacing material being distributed more densely closest to the free end and progressively less densely away from the free. Such a distribution of the hardfacing material ensures that the axially - extended region wears to a tapered form and that no extensive abrupt shoulder develops between that region and an adjacent unprotected region. In the box joint of Fig. 1, a split steel wear protector band 20 is secured in a recess by welds 27, 28 and also has its two halves welded together. The band has circumferentially - extending rows of hardfacing elements, the number and disposition of the elements in the rows being such that the elements can be considered as arranged in triangular plots G. The elements are rectangular and can be orientated axially of the joint, as shown or on the skew. In another embodiment, the ring 20 is retained in an undercut groove by circumferentially extending strip of malleable metal hammered into one end of the groove. Relative rotation between the ring and the joint in such latter case is prevented by disposing friction paste between the base of the groove and the ring. Equivalent wear protecting arrangements may also be embodied in the mating pin joints.

Patent GB-692024-A (GB)
Title: Film forming compositions
IPC: C09D11/10
Filed: 1949-04-25
Abstract: A coating composition comprises free furfuraldehyde and a partial condensate of a furfuraldehyde (i.e. furfural, polymerized furfural or a short-chain alkyl substituted furfural) and an aryl diamine, wherein the two amino groups are substituted directly on the aromatic nucleus, the condensate being obtained by reacting the furfuraldehyde with the diamine in the ratio by weight between 2.8 : 1 and 4 : 1, and the free furfuraldehyde being the excess remaining after formation of the condensate. The composition may be applied in a liquid state to an article to be coated and hardened thereon by the action of heat or by exposure to an acidic gas, e.g. sulphur dioxide. The presence of iodine in the composition increases the speed of hardening.  The compositions may be modified by incorporation of cellulose esters or ethers, waxes, natural or synthetic resins, e.g. phenol-formaldehyde resins (the term phenol includes all homologues and polyhydric phenols such as resorcin, naphthols and compounds such as diphenylol-methane and -propane), and alkyd resins, wetting agents and plasticizers such as triphenylphosphate, tricresylphosphate, triacetin, camphor, p-tolune-or p-xylene-sulphonamide, diethylphthalate, dibutylphthalate and dibutyl tartrate. Condensation of the furfuraldehyde and diamine, the mixing of which engenders heat, may be controlled by cooling the mixture during the addition of the aldehyde to the diamine, and the condensation may be effected in the absence or presence of the above modifiers.  In examples, compositions are made by mixing a neutral polyoxyethylene stearyl phosphate, an oil-modified glycerol-phthalate resin, ethyl cellulose and 2 : 4-diaminotoluene with (1) heat-polymerized furfural and tetrahydrofurfuryl phthalate, and (2) furfural and dibutylphthalate.  The compositions, to which pigments, dyes, &c. may be added if desired, may be applied as films on carbon paper or objects.  Quick setting inks may be made by dispersing colouring matter in the compositions together with organic vehicles or diluents such as tetrahydrofurfurylphthalate (which requires an emlusifier) or a heavy refined mineral oil.  The ink may be hardened by means of an acidic gas.  Printing inks exemplified are made by incorporating (1) carbon black and (2) iron blue into a mixture of furfural, an oil-modified glycerol phthalate resin, a neutral polyoxyethylene stearyl phosphate, ethyl cellulose, tetrahydrofurfurylphthalate and 2 : 4-diaminotoluene, and (3) by mixing together furfural, 2 : 4-diaminotoluene, carbon black, heavy refined mineral oil and a vinyl acetate polymer.  Specification 542,331 is referred to.

Title: Jet fuel compositions
IPC: C07F5/02
Filed: 1957-04-05
Abstract: Jet fuels are improved by the addition of fuel-soluble esters of boron acids, either by dissolving the ester in the fuel, or by adding the ester to the fuel to precipitate impurities, the precipitate being filtered off to leave fuel containing a residual amount of the ester which may be allowed to remain, or may be removed by washing with water to obtain an improved fuel, to which further ester may be added, if desired.  In examples, fuel compositions are obtained by dissolving diphenyl phenylboronate, dodecyl tetraborate, methyl dibenzylborinate and di-(catechol) pyroborate in jet fuels, and by adding methyl metaborate, n-propyl orthoborate, n-butyl metaborate, phenyl metaborate, hexyl metaborate and tetramethylphenyl metaborate to jet fuels, and filtering off the precipitates which are formed to obtain fuels containing residual amounts of the esters; after removing the precipitate formed by the tetramethylphenyl metaborate, the remaining ester is removed by washing with water, and the 2-methyl-2,4-pentanediol ester of n-octyl boronic acid is added to the fuel.  Other esters mentioned are methyl orthoborate, butyl orthoborate, isobutyl orthoborate, decyl orthoborate, ethyl metaborate, isopropyl metaborate, cetyl metaborate, tetraphenyl tetraborate, tetrapropyl pyroborate, methyl dimethylborinate, octyl di-sec.-butylborinate, methylethyl methylboronate, didecyl butylboronate, cyclohexyl orthoborate, cyclohexyl thiometaborate, dicyclohexyl cyclohexylborinate, cyclohexyl tetraborate, tetracyclopentyl pyroborate, triphenyl orthoborate, benzyl metaborate, tetratolyl pyroborate, phenyl dibenzylborinate, di-(phenyl)-phenylboronate, diphenylmethyl orthoborate, tolyltributyl pyroborate and dimethyl phenylboronate.
