Title: Coupling for steel pipes for withstanding high pressures, and showing little tendency to seizing
Inventor: PLAQUIN BERNARD
IPC: E21B17/042
Filed: 1983-02-18
Granted: 1986-09-25
Abstract: The invention relates to a joint for steel pipe, which is oil-tight at high pressure, being of the type including at least one pair of slightly conical sealing surfaces arranged at at least one end of the male member or of the female member, and is insensitive to seizure. This joint is characterized by the fact that the first contact 5 of the sealing zone lying at the end of one member occurs against the corresponding sealing surface of the other member and that at the time of this first contact the taper of the sealing surface which is situated at the end of one of the members of the joint is less than the taper of the corresponding sealing surface which is situated on the other member of the joint, the sealing surfaces at the time of tightening the joint, becoming applied against one another with a contact pressure sufficient to ensure oiltightness. <IMAGE>

Title: Fabric softening composition
Inventor: PARSLOW MICHAEL WILLIAM
IPC: C11D3/20
Filed: 1983-02-08
Granted: 1989-06-01
Abstract: A fabric softening composition comprises an aqueous base, a cationic fabric softener and up to about 10% lanolin. The cationic softener and lanolin are preferably in the ratio of 20:1 to 1:20 and the level of cationic softener in the composition may be from 0.5% to 30%. Other conventional fabric softening composition ingredients may be present. The lanolin may be replaced by a lanolinlike material such as derivatives thereof or one or more of the active constituents of lanolin either extracted therefrom or derived from other sources. The presence of lanolin in the composition improves the viscosity and performance thereof.

Title: Method of making a gasket
Inventor: BATE CECIL ALBERT
IPC: F02F11/00
Filed: 1984-08-17
Granted: 1987-01-29
Abstract: A method of making a gasket by pressing particles of expanded graphite in a mould onto the opposed faces of an apertured reinforcement plate to compact the particles and unite them with the plate makes use of a mould assembly comprising a base plate, first and second moulding rings, and a moulding punch which is apertured to conform with the apertures of the reinforcement plate. The first and second moulding rings are positionable above the base plate to form lower and upper mould recesses, into which expanded graphite is successively charged, so enclosing the apertured reinforcement plate. The punch is then operated to compact the graphite particles and unite them with the reinforcement plate. Compaction in the mould assembly can produce either the finished gasket or at least a composite whose graphite layers are firm enough to be handled outside the mould assembly to permit further compaction. The method is specially applicable to the manufacture of cylinder head gaskets for internal combustion engines.

Title: Coacervation process for microencapsulation and microcapsules prepared by such coacervation process
Inventor: BAKER RICHARD
IPC: B01J13/02
Filed: 1984-05-09
Granted: 1988-03-10
Abstract: In an improved complex coacervation process for micro-encapsulation of core ingredients that are partially soluble in the microcapsule walls the core ingredient is first mixed with a coacervation adjuvant selected from an ionizable colloid, an ionic surfactant and an ionizable long-chain organic compound prior to forming a first colloidal emulsion of core ingredient, and, after combining the first emulsion with a second colloidal solution and cooling to cause gelation, a water-soluble wax derivative is added. No pH adjustment or dilution is necessary, and very high yields of non-agglomerated microcapsules are obtained, both in terms of quantity of microcapsules and content of core ingredient. When deet is the core ingredient there is obtained a long-lasting mosquite repellent.

Abstract: The system uses a 3B2T line code, i.e. one in which sets of three or triplets of binary digits are converted into pairs or duplets of ternary elements. All nine of the possible ternary duplets are used, in such a way that the same ternary duplet does not occur twice consecutively. This is done in one version by using the ninth duplet 00 as a repeat indicator, and in the other version by a conversion process in which each conversion operation takes into account the result of the preceding operation.

Abstract: A method for improving utilization of limestone in a sodium-limestone double alkali flue gas desulfurization process. Spent alkaline absorber solution, containing sodium sulfite and sodium bisulfite, is diverted for regeneration treatment in a series of stirred tank reactors, where it is contacted with the limestone regenerating agent. Dilute slurry from the last reactor is concentrated in a thickener, and the concentrated underflow slurry from the thickener is then treated further in an after-reactor circuit. Since the thickener underflow slurry contains residual unreacted limestone, the slurry is contacted with a side stream of spent alkaline absorber solution in the after-reactor circuit to promote further reaction of residual limestone before the solids are separated and discarded.
