Abstract: 1297806 Aluminosilicophosphate zeolites UNION CARBIDE CORP 26 Nov 1969 [27 Nov 1968] 57783/69 Heading C1A [Also in Divisions C2 and C5] A crystalline aluminosilicophosphate zeolite (claimed per se) has the molar composition, expressed in terms of oxide: where M is an alkali or alkaline earth metal or ammonium, y ranges from 0À1 to 0À75 and x+y ranges from 0À95 to 2À31 and wherein the phosphorus is present as a crystalline framework substituent. When M is sodium, the zeolite may be prepared by digesting a reaction mixture containing alumina, silica, phosphate and Na-cations at a temperature between 50‹ and 220‹ C. The reaction mix may be prepared by combining NaAlO 2  solution, H 3 PO 4  solution and an SiO 2  source or AlCl 3 -H 3 PO 4  in solution may be precipitated by adding NaOH to bring the pH to about 7À5, and then blending with silica slurry and NaOH solution, or preferably by adding aqueous solutions of NaAlO 2 , NaOH and H 3 PO 4  to a stirred aqueous slurry. Typical reactant compositions in terms of mole oxide ratios are Na 2 O/Al 2 O 3 =1À4-3À2, SiO 2 / Al 2 O 3  = 1À2-2À0, P 2 O 5 /Al 2 O 3 = 0À5-1À3 and H 2 O /Al 2 O 3 = about 3À0 to 200. In the preferred method H 2 O/Al 2 O 3 = about 110 and the mix is digested at 100-150‹ C. for 12-96 hrs. (Example IV) Potassium, calcium and ammonium aluminosilicophosphates may be prepared by ion exchange of their chlorides with a sodium aluminosilicophosphate prepared by the preferred method. The Ca<SP>2+</SP> zeolite may be used as a catalyst for the dimerization of isobutylene (Example V-see Division C5) and the dehydration of methanol (Example VI-see Division C2)

The solution or extract of coal may be made using a solvent containing at least one aromatic ring and boiling above 200‹ C., for example a polynuclear aromatic hydrocarbon. The coal may contain between 80 and 90% by wt. of carbon, and the solution or extract may contain between 40 and 60% by wt. of solvent. The solution or extract may be melt spun to form the fibre or filament. The fibre, filament or film may be drawn or stretched whilst being extruded or spun or at some point between completion of spinning and winding on to a receiving roll. The oxidation step may be achieved using a gas containing oxygen molecules at an elevated temperature, which molecules may be ozone molecules. The preferred gas used is air. The oxidation step may be performed under tension. The carbonization temperature may be between 800‹ and 3000‹ C. The process may be performed continuously by extruding the film, filament or fibre at 100‹ C. for example and passing the product directly into a furnace having suitable atmospheres and temperature gradient. The fibres produced may be used to reinforce a polymer e.g. epoxy resin matrix.

Abstract: 1326625 Continuous casting DEMAG AG 9 Sept 1970 43098/70 Heading B3F A strip or slab or metal, e.g. a continuously cast slab being guided from a mould, passes through a cooling zone where a water spray 2, at any instant wets a band area 10 across the strip or slab 1; the kinetic energy of the water 7 striking the edge regions of the strip or slab is less than that of the water striking the middle, so that the cooling effect increases from the edges towards the middle. Guide rollers for the slab may each be sprayed over their length in a similar way to the metal. The spray head is swept to and fro to shift steam bubbles. Instead of the spray being produced by a single spray head 5 with a slot orifice there may be two adjacent heads 5, 11, Fig. 2, one behind the other and having different sized orifices and capable of separate operation. Alternatively, there may be two spray heads side-by-side and each spraying just over half the strip or slab so that, where they overlap, the kinetic energy of the water is increased. The spray heads are spaced along a supply pipe 9 and connections to this may be by hose to permit adjustment, by screw gear and motor, of the distance from the slab face, e.g. during casting or to accommodate different slab widths or for tilting of the nozzles.

Title: Manufacture of toric single vision spherical or aspheric bifocal multifocal or progressive contact lenses
IPC: G02C7/04
Filed: 1993-11-23
Abstract: A method for making a finished aspheric single vision, spherical or aspheric bifocal, multifocal or progressive addition contact lens includes the step of fitting a patient requiring a near correction with a single vision spherical or aspheric contact lens for optimal distance vision and comfortable fit. If desired, the patient is then over-refracted to determine the required near correction to be embodied in the contact lens. A portion of the optic corresponding to the center location of the pupil is marked on the convex side of the optic to form an optical preform. In some instances, the lens may not stabilize on the cornea to a suitable degree. Thus, it is often desirable to stabilize the contact lens, either prior to placing the lens on the patient or after rotation is observed on the cornea of the patent. Observation of rotation on the patient's cornea is enhanced by means of the mark that is used to designate the center of the patient's pupil. The optical preform is removed from the eye of the patient and the concave side of the optical preform is marked at a position corresponding to the mark on the convex side that denotes the center of the pupil. The mark disposed on the convex side of the optical preform is removed. A specified volume of polymerizable resin is placed in a mold embodying the required correction, which includes an add power zone so that the resin fills the intervening space between the mold and the optical preform. The add power zone is aligned on the optical preform to a predetermined position with respect to the mark on the optical preform designating the center of the pupil. The resin is then polymerized the optical preform is demolded to obtain the finished contact lens having the required correction.
