Patent GB-757883-A (GB)
Title: Method of filling the pores of carbon bodies
Inventor: MCKEE JAMES HUNTER
IPC: C04B41/82
Filed: 1951-03-22
Abstract: The pores of a solid carbon body, or at least the surface pores thereof, are filled by expelling the contents of the pores, filling the pores by immersing the body in a hardenable liquid mixture of furfural and an amine and heating the impregnated body at at least 100 DEG C. to harden the mixture within the pores.  The pores may be evacuated by subjecting the body to subatmospheric pressure and the body may be under atmospheric or subatmospheric pressure when immersed in the liquid mixture.  Alternatively the expulsion of the pore contents and the filling may be effected simultaneously by heating the liquid mixture, while the body is immersed therein, at the boil for a period insufficient to harden the mixture.  The impregnated body should be heated to at least 200 DEG C. preferably 300 DEG C., and may be heated above the carbonization temperature of the hardened pore filling, e.g. at 1000 DEG C.  Amines may be aliphatic, aralipathic, aromatic, or heterocyclic amines including aliphatic amines containing at least two primary amino groups or at least one amino group and at least one hydroxyl group, e.g. monoethanolamine, N-hydroxyethylethylene diamine, ethylene, propylene, or hexamethylene diamines, polyalkylene polyamines, aniline, p - phenylene diamine, piperidine, or benzylamine.  The mixture may contain 30-60 per cent amine, but it is preferred to use a proportion of furfural greater than the amine.

Abstract: 890,329. Mineral-mining; tunnel linings; goaf-filling. BERGWERKSVERBAND ZUR VERWERTUNG VON SCHUTZRECHTEN DER KOHLENTECHNIK G.m.b.H. March 6, 1958 [March 6, 1957; April 5, 1957], No. 7195/58. Classes 68(1) and. 85. A method of mining mineral by the longwall system from a steeply inclined seam comprises first driving at the working limits of the seam two parallel roadways extending along the line of strike of the seam, secondly driving a pair of parallel drifts extending between and at right angles to the limits of the roadways, and then removing mineral from the seam by attacking the upper face simultaneously at a number of points spaced along the upper exposed face of the seam by winning means that cause removal of the mineral along the face, down a drift to conveyer means in the lower roadway, the winning means, preferably including ploughs, having associated therewith means that as the face is advanced downwards seal of the working area from the worked out zone of the seam. This sealing means may be an inflatable tube or tubes attached to the roof support system of the winning means for advance therewith. Alternately the means may comprise a stack of wire mesh panels, the stack extending between the drifts and the panels being so interconnected that the panels are automatically drawn from the stack as the support system advances downwards to lie at regularly spaced intervals parallel to the advancing face in the worked out zone as the uppermost panel is anchored in the zone adjacent the upper road. The roadways and drifts can be so driven in the seam before mining commences as to extend from the top of the seam to well below the seam so that the roadway can still be of use after the roof of the worked out space sinks to the floor thereof.

Title: Improvements in or relating to envelopes for aircraft
IPC: B64B1/00
Filed: 1926-03-18
Abstract: 249,542. L³bbecke, W. March 21, 1925, [Convention date]. Acrostats; planes, construction of; parachutes. -An envelope of variable form for rigid and non- rigid balloons, aircraft planes and parachutes is composed of a number of triangular or quadrangular pieces of fabric, netting, &c. having intersecting threads, joined together in such a manner and so disposed that variations of the relative angles of the strands of the material may take place under stresses in certain directions and thereby change the shape of the envelope as a whole. Pieces of fabric mav be cut and set so that one or both sets of intersecting threads is or are parallel to one or two sides, of a triangle, which sides would then be indeformable in length, or the threads may be set in other predetermined directions to limit deformation in one direction, or specially woven net which may have knotted intersections may be used. The edges of the pieces are strengthened by sewn on bands. To control the variation of shape, pieces of indeformable shape may be introduced where necessary. A. balloon is described capable of varying from a prolate to an oblate spheroid as the gas expands or contracts and the load is carried bv an external netting having diagonal connections across the meshes, different diagonals becoming stressed as the balloon changes in shape. The load may be transferred to an internal suspension arranged parachutewise on the upper inner part of the balloon, the balloon then being assisted to assume the spherical and finally the oblate form. Should the balloon collapse it forms a parachute. The fabric or net may be proofed or provided with plates O or strips to form overlapping scales as shown in Figs. 10 and 11, as applied to deformable planes of an aeroplane. The planes can be moved as shown independently on the two sides of the machine. The fabric mav be of interwoven metal strips or plain or twilled fabric of cotton linen, silk, straw, wood, hair, rubber or wire. The displaceabde quadrangles allow movements similar to those of a fish during flight by alternately exerting a pull on one or the other side of the balloon envelope. The expansion of the sections in the directions not parallel to the threads may be limited by bands of fabric leather or perforated sheet metal, for example at the nose of an airship. In the case of a parachute the unalterable sides of the fabric sections are made tension and compression members and their nodal points connected by rods in one or more rings to a central vertical rod, the stretch of the quadrangles when in tension corresponding to the lengths of the rods extending from the rings.
Patent GB-571018-A (GB)
Title: Improvements in or relating to the production of pigmented linear polyamides
IPC: C08J3/20
Filed: 1943-05-13
Abstract: Pigmented linear polyamides, including polyesteramides are produced by heating to amide-forming temperature (e.g. 180-300 DEG  C.) an aqueous dispersion of a finely-divided pigment containing a protective colloid a polyamide-forming reactant or reactants and such additional water as is necessary to render the mass fluid before polyamide-forming temperatures are reached.  In the preferred method, the pigment and, if desired, a dispersing agent are ground in water to the desired particle size which is generally less than 4 microns, the protective colloid is added and the polyamide-forming materials with the required additional water and the mixture is heated as described in Specification 506,125. The preferred protective colloids are protein salts and the preferred dispersing agents are the sodium salt of b -naphthalene sulphonic acid-formaldehyde reaction product, the sodium salt of lignin sulphonic acid or the polyether from hexylphenol and ethylene oxide.  Ammoniacal casein or gelatin is a suitable colloid for use with alkaline dispersing agents.  Gum arabic is suitable for use with an acid dispersing agent, e.g. tannic acid. In example 1 an aqueous dispersion of carbon black was prepared by ball milling carbon black, water and a dispersing agent, the dispersion was diluted with aqueous alkaline casein solution and the mixture added to aqueous hexamethylene - diammonium adipate containing acetic acid as stabiliser.  The mixture was heated as described in Specification 506,125 and extruded as a monofil.  In example 2 alkaline aqueous casein was mixed with a self-dispersible grade of titanium dioxide, the surface of which contains salts which function as dispersing agents.  Aqueous hexamethylene diammonium adipate was added and the mixture passed through a disper-mill.  The dispersion was added to the bulk solution of hexamethylene diammonium adipate, the mixture was heated and spun into filaments.  The pigmented polyamides may be used for filaments, films, fibres, moulding powders or coating compositions.  Specifications 461,236, 461,237 and 554,718 also are referred to.
