Title: Improvements in or relating to reconstituted tobacco products and method of making same
Inventor: STRUBEL DAVID GARNET
IPC: A24B15/12
Filed: 1965-08-19
Abstract: 1,070,819. Reconstituting tobacco. BROWN & WILLIAMSON TOBACCO CORPORATION.. Aug. 19, 1965, No. 35714/65. Heading A2C. A method for making reconstituted tobacco products in which water and finely-divided tobacco elements are made into a mixture and the mixture is formed into a predetermined configuration such as a sheet or rod and then dried, comprises the steps of flash freezing the configuration before drying by subjecting it to a temperature substantially lower than the freezing point of water so that the configuration is rapidly set and drying the configuration in its frozen condition by subjecting it to a temperature below the freezing point of the mixture and to a reduced pressure at which water is sublimed from the solid to the vapour state. The reduced pressure under which the configuration is dried is less than approximately 5mm. Hg absolute. Sheet configurations are cast on a belt before freezing whilst rod configurations may be formed by extruding a tobacco slurry, casting it, or moulding it to the required shape. Longitudinal air channels 17 may be made in the rod 16 by e.g. wires, before freezing. The rod may be formed in cigarette or cigar lengths or cut into such lengths, and provided with a filter and wrapped in the usual manner after drying.

Title: Manufacture of shaped carbon bodies
IPC: C25C7/02
Filed: 1961-10-10
Abstract: The invention comprises shaped carbon bodies made by mixing uncalcined petroleum coke particles obtained by the fluid coking process and containing 5.0 to 7.0 weight per cent of volatile matter measured at 1750 DEG  F., with from 10 to 25% by weight of the mixture of a carbonaceous binder, having a softening point between 120 DEG  and 300 DEG  F., at a temperature above the softening point of the binder and between 130 DEG  and 375 DEG  F.; moulding the mixture under a pressure of at least 2,000 p.s.i. at a temperature near the softening point of the binder; and baking the moulded mixture by heating for from 10 hours to 8 days to at least 1,400 DEG F. and holding the final temperature for 1/2 to 20 hours.  The products may be electrodes for use in the electrolytic production of aluminium and, as such, should have a minimum compression strength of about 4,400 p.s.i., a minimum seal density of about 1.40 g./c.c. and a maximum resistivity of about 0.0035 ohm inch. These values are attained when two or more component coke fractions are used having a mean particle diameter ratio of at least 3 to 1.  Preferably, when electrodes are produced, 15 to 50% of the coke is resized by grinding so that 25 to 60% of the ground part passes a 325 mesh sieve (Tyler Standard) and all passes a 150 mesh sieve.  Coal tar, or petroleum, pitches are used as binders and preferably have coking values of 40 to 80 weight per cent and benzene and nitro-benzene insolubles of 10 and 40% and 5 and 30% of the binder respectively.  Pressures of 2,000-6000 p.s.i. are quoted and baking temperatures of 1600 DEG  F. or up to 2,400 DEG  F., or higher when lower resistivities are required.  The heating is carried out gradually during the first stage of baking until the final temperature is attained and then held at that temperature for a relatively shorter time.  Carbon blanks, bricks, brushes, tubes and pipes may also be made and where strength is the main consideration soaking should be effected at a relatively lower temperature, e.g. 1,650 DEG  F. for about 48 hours and the coke preferably contains a relatively large proportion of finer particles. Examples are provided of the preparation of electrodes and the physical properties of the products are compared with a product obtained from an uncalcined delayed coke.

Abstract: 840,781. Grinding tools. AMERICAN OPTICAL CO. Nov. 22, 1957 [Jan. 18, 1957], No. 36545/57. Class 60. An abrading tool for surfacing a lens blank, to a desired shape, comprises a replaceable facing 13, Fig. 2, of relatively thin foraminous material which is contoured into engagement with the body 11 of the tool and provided with means either forming part of the sheet or by a separate clamp for retaining it in position. The facing, which may be of soft galvanised steel, bronze or nickel wire mesh, is initially sprayed on one side with a thin layer of slowsetting waterproof adhesive to which, before it has set, short lengths of synthetic or natural fibrous material 15, Fig. 4, such as rayon or cotton are applied ; this material is then subjected to electrostatic or like treatment to cause the major portions of the fibres to stand away from the adhesive coating. The facing 13 is secured to body 11 of the tool by applying a second adhesive coating 16 to either the facing 13 or the tool ; the latter may be of cast-iron, sintered metal or plastic and its surface may be convex or concave of substantially the desired curvature to be formed on the blank. In another embodiment, the facing is coated with a heatsensitive adhesive, such as a mixture of 75% rosin and 25% hydrogenated methyl ester or rosin, and bonded to the tool which is heated sufficiently to soften the adhesive ; alternatively, a pressure-sensitive adhesive may be used. In a further embodiment, the facing is cut large enough to overlap the sides of the tool and retained in position by a spring-type clamp 18, Fig. 6, or other suitable clamping means. In use, the tool is mounted on an oscillating arm 19, Fig. 7, and the lens blank 20, which is adhesively-attached to a holder 20a, describes, by means of alignment-retaining means 21 and a crank spindle 22, a path of movement relative to that of the tool so that a scrubbing action takes place on the surface of the blank while an abrasive slurry 23 is applied to the facing of the tool. A plastic polishing pad of substantially the same thickness as the wire mesh facing may be used to replace the latter during polishing of the lens blank.
