Title: Rotary buffing sections
IPC: B24D13/08
Filed: 1953-04-23
Abstract: 725,203. Buffs. SCHLOSS, M. April 23, 1953, No. 11196/53. Class 60 The fabric plies of an annular rotary buffing section have relatively stiff warp threads and relatively soft filler threads and are bias cut and helically wound so that all warp threads in the outer zone of the section are inclined from a radial direction in the same rotational direction, the plies being secured together at the inner zone of the section. The section is formed by cutting a number of strips 38, Fig. 11, diagonally from a strip of material and securing such strips together so that all of the warp threads 36 are parallel. The continuous sfrip thus obtained is rolled tightly into a hollow cylinder one end of which is contracted to form a series of uniform convolutions 24, Fig. 1, held together by a hub plate 26, a binder ring 27, and a series of metal staples 28, Fig. 3. The latter also serve to provide driving engagement between axially assembled sections. The end plies of each section are rendered continuous by sewing the free ends of the strip of material to severed portions 43, 44, Fig. 13, of adjacent convolutions. Rotation of the buff in the direction indicated by the arrow in Fig. 3 causes the warp threads 36 to engage the workpiece 54 with a rearward slant .and so produces a polishing action, while rotation in the reverse direction produces a roughing or cutting action. The stiffness of the warp threads may be obtained by the use of heavier or hardertwisted threads, by.sizing the threads, or by using a different material from that employed from the filler threads. Cooling air is blown through spaced openings 34 in the hub plates 26 by fan blades 33 and 33a, Fig. 5, which are oppositely inclined so as to be effective for either direction of rotation and mounted on an auxiliary plate 32 rotatably adjustable on the hub plate 26 to regulate the effective size of the opening 34. Cooling air also flows radially outwards through interstices 25 under the action of centrifugal force.

Filed: 1943-07-21
Abstract: Styrene, a -methyl styrene, or a nuclear alkylsubstitution product thereof, separately or in any combination thereof are polymerized by the action of heat in the presence of a peroxidic catalyst containing the radicle of an unsaturated organic acid and in the presence of a non-solvent-diluent (i.e. a solvent for a monomer, but not for the polymer), at a temperature not greater than 150 DEG  C.  The non-solvent-diluent may be methanol, ethyl alcohol, amyl alcohol, di-acetone alcohol, acetic acid or heptane, and may contain a small amount of water.  The organic acids of the catalyst are those compounds which contain a pair of aliphatic double-bonded carbon atoms, but which have no pronounced tendency to polymerize themselves, e.g. crotonic acid and cinnamic acid. The non-solvent diluent is present in a concentration of from 10-60 per cent by weight, and the catalyst in an amount of from 0.05-1 per cent by weight, of the polymerization mixture.  In the examples, mixtures of (1) styrene, methanol and crotonyl peroxide; (2) styrene, ethanol, water and crotonyl peroxide; and (3) styrene, methanol and cinnamyl peroxide are used.
Patent GB-883264-A (GB)
Title: Aluminium oxide filler for the brightening of paper
IPC: C01F7/32
Filed: 1960-04-04
Abstract: An aluminium oxide filler for paper is prepared by incomplete thermal decomposition of hydrated aluminium sulphate to produce an alumina containing more than 5% SO3.  The initial aluminium sulphate, preferably the octadecahydrate, may be prepared by treating Bayer aluminium hydroxide or calcined kaolin with sulphuric acid and separating the silica before crystallising the octadecahydrate. Alternatively the silica from the kaolin may be left as an additional filler.  According to an example, crystalline aluminium sulphate octadecahydrate is injected in suspension with air into the upper end of a conical heating chamber, at the lower end of which combustion gases enter tangentially.  Effluent gases leave tangentically from the top of the chamber and deposit the entrained aluminium oxide formed in a cyclone.  The outlet temperature may be from 800-1100 DEG C. Reference is made to the employment of such alumina as a component in a bleached sulphite cellulose which also contains aluminium sulphate.  Specification 673,336 is referred to.
Patent GB-420520-A (GB)
Title: Improved process for chlorinating hydrocarbons
IPC: C07C17/12
Filed: 1933-04-24
Abstract: Naphthalene is chlorinated by passing chlorine through the molten hydrocarbon in the presence of a halogen carrying catalyst until a product containing 40--44 per cent of chlorine is obtained, distilling the product and further chlorinating the distillate.  The product may further be treated with a solvent, e.g. trichlorethylene or white spirit, a decolourizing agent, e.g. fuller's earth or carbon, crystallizing and melting, to purify.  The partially chlorinated naphthalene after distillation and recrystallization, if desired, may be further chlorinated by dissolving in carbon tetrachloride and treating <PICT:0420520/IV/1> at boiling point with chlorine in presence of a halogenating catalyst, with or without the presence of iodine.  According to an example, naphthalene, containing a small quantity of ferric chloride, is heated to 110 DEG  C., chlorine passed in a fast stream starting at 85 DEG  C., the temperature after rising to 170 DEG  C. is held there until 40--44 per cent chlorine is absorbed, the product is distilled at 300--330 DEG  C., if necessary repeatedly and the distillate is further melted with a small quantity of ferric chloride and treated with dry chlorine while continually raising the temperature to keep the mass melted.  The product may be purified by neutralizing after the addition of trichlorethylene, shaking up with decolourizing earth, crystallizing and melting. The Figure illustrates an apparatus for effecting the further chlorination in the presence of carbon tetrachloride.  The partially-chlorinated naphthalene dissolved in carbon tetrachloride is introduced into vessels a, b, c surmounted by inlet pipes m for the chlorine and outlet pipes g for the solvent vapour and unabsorbed chlorine.  Condensers j are also provided from which pipes n lead to the next succeeding absorption vessel. The chlorine dissolves partly in the condensed solvent passing round the U-bends k before entering the absorbing vessels.  The hydrochloric acid generated is absorbed in milk of lime in a vessel e, a trap d being provided to prevent milk of lime from entering the reaction chambers.  Pressure above atmospheric is maintained throughout the system by compressed air admitted at the cock r.  Fresh, partly chlorinated naphthalene in carbon tetrachloride is introduced at cock p in the vessel c to displace the contents of the vessels c, b and a successively through the cock q.  A cock r is preferably provided in vessel e to enable liquor to be withdrawn at the cock u while forcing in fresh milk of lime at t.  Water may be employed instead of milk of lime as absorption agent for the hydrochloric acid.  An indicating device is desirably included in the first chlorination vessel showing when no more acid is present and full chlorination has been effected.
