Title: Improved centrifugal husking machine for coroze nuts and similar hard fruits
IPC: A23N5/00
Filed: 1926-06-22
Abstract: 253,949. Bertocchi, G., and Marina, G. June 22, 1925, [Convention date]. Hulling, husking, and decorticating. - A machine for husking coroze nuts and similar hard fruits by centrifugal force comprises a revolving lower cone 2 into which the nuts are fed from holes in an upper cone 1, and from which they are thrown against the upper cone 1 revolving at a different speed, or being stationary so that the nuts travel along the helical ribs or blades or roughened surfaces 4 of this cone and then fall back into the lower cone 2. The lower cone is provided with helical blades 3, and its curvature near the bottom edge is eased to give smooth transfer of the nuts. To distribute the nuts uniformly a slowly rotating centre cup 5 receives the nuts that fall back from the upper cone and pass them to the lower cone. The nuts are discharged by opening a butterfly valve 9 by a hand lever 7. To cool the machine an air opening 8 is provided in the upper cone so that air is drawn down and discharges the detached husk at the periphery where the two cones meet. The blade and rough surfaces of the upper cone are replaceable, while to facilitate erection the cone is cast in four segments. The stationary cone is carried on a ring which can be raised or lowered by gearing to adjust the relative curvature at the edge to larger or smaller nuts.

Title: Process for the manufacture of an embossable rubber composition particularly suitable for artificial leather
Filed: 1934-05-28
Abstract: Chlorinated rubber is added to rubber compositions to reduce their resiliency and allow them to be embossed, particularly in the manufacture of a leather substitute, the mixture obtained being vulcanized.  An addition of 10 per cent is sufficient, but up to 60 per cent may be added.  Hot or cold vulcanization or the two processes consecutively may be employed.  Articles may be made of the composition or an outer film which may be of different colour from the base may be applied by vulcanization. The surface may be coated with a cellulose lacquer, in which case, a softener compatible with both rubber and the lacquer such as castor oil, linseed oil, sipalin, should be used in the rubber composition, or an increased proportion of chlorinated rubber should be added.  When an oxidizable oil is added, the surface-hardening process described in Specification 400,001, is applicable.  A specified composition is 100 parts of rubber, 3 parts of sulphur, 1 part of accelerator, 30 parts of oxidizable stand oil, 20 parts of chlorinated rubber, and 10 parts of colouring matter.

Title: Method of producing synthetic resins
IPC: C08G63/48
Filed: 1935-05-31
Abstract: Oil-soluble resins are prepared by reacting glycerol, phthalic acid, a polybasic aliphatic acid and a fatty acid, the polybasic aliphatic acid being in amount more than 15 per cent, but no more than equimolecular proportion based on the amount of phthalic acid, and the amount of fatty acid being in excess of 1 mol. for each mol. of dibasic acid.  Suitable polybasic aliphatic acids include malic, maleic, fumaric and succinic acids.  The resins are soluble in benzene, toluene, solvent naphtha, petroleum distillates, acetone, alcohol, and they are miscible with oils, resin varnishes, natural and synthetic resins, phenol-formaldehyde resins containing a natural resin or an ester gum and nitrocellulose.  When it is desired to blend the product with chinawood oil it is desirable to produce the resin in the presence of the oil.  In examples, soya bean oil fatty acids, phthalic anhydride, maleic acid, and glycerol are used; the fatty acid derived from linseed, perilla, wood, poppyseed, cotton seed, olive, castor, sunflower, corn, sesame, rape seed, rubber seed or fish oils may replace the soya bean oil fatty acids wholly or in part.

Patent GB-459436-A (GB)
Title: Manufacture of anhydrous ferric sulphate
IPC: C01G49/14
Filed: 1935-06-04
Abstract: Anhydrous ferric sulphate is prepared by treating a solution of the salt with the anhydrous salt in amount sufficient to remove substantially all the water of solution under conditions of temperature sufficiently moderate and/or conditions of acidity preventing the formation of material quantities of insoluble products, and expelling the water of crystallization.  The ferric sulphate solution may be obtained by reacting sulphuric acid of 35--40 DEG  B<\>ae., with an excess, e.g. a 20 or 25 per cent excess, of ferric oxide or burnt pyrites.  Water may be added to prevent separation of acid salts.  After about 27 to 50 per cent of the p acid has reacted, the solution can be concentrated, e.g. to 59 or 60 DEG  B<\>ae., at normal boiling temperature if separation of crystals is prevented and the time of heating does not exceed say 6--7 hrs. The concentrated solution is intimately admixed with the finely divided anhydrous salt under controlled temperature conditions.  A temperature below 70 DEG  C. would be ideal but, to obviate solidification, the feed liquor is kept at, e.g. 80--90 DEG  C., the resulting temperature on admixture being say 105--110 DEG  C. Such temperatures can be maintained within reasonable limits of time if sufficient free acid is present, viz. 3--10 per cent free SO3 based upon total sulphate radical.  With 3--6 per cent free acid, the time limit is about 1--2 hrs.  With less free acid the temperature should not rise above 80--85 DEG  C. for any extensive time.  The dry product may be calcined by passage through a rotary kiln at about 450 DEG  C.  In examples: (1) ground anhydrous ferric sulphate, which may be at 100 DEG  C. or more, is fed to a screw conveyer, and a 60 DEG B<\>ae. solution at say 90 DEG  C. is sprayed on in a number of fine streams, preferably over one third the length. The product forms hard granules; (2) the hot solution and anhydrous salt are fed continuously to a rotary mixing drum which discharges continuously.
Patent GB-622657-A (GB)
Title: Improvements in or relating to the preparation of oil-soluble phenolic resins
IPC: C08G8/28
Filed: 1946-05-28
Abstract: Oil-soluble phenolic resins for use in varnishes or coating compositions are prepared by reacting an aldehyde, e.g. formaldehyde or paraldehyde, with one or more monohydric phenols having in the o- or p-position a cyclohexyl group or an alkyl group higher than methyl, in the presence of a sulphonic acid of the phenol or of one of the phenols in the mixture or of p-tert.-amyl phenol, and dehydrating the reaction mixture.  The resins may be dispersed in drying, semi-drying or other oils, e.g. fatty oils which have conjugated and non-conjugated double bonds and which dry by oxidation or by heat-polymerization, such as tung, oiticica, dehydrated castor, linseed, soya bean, rape seed and perilla, fish oils and glycerides of fatty acids having 6 to 22 carbon atoms in the chain.  Natural resins, such as rosin, copals, elemi and mastic and synthetic resins such as coumarone or phenolic resins, plasticizers and other ingredients, e.g. driers such as solutions or mixtures of organic salts of lead, cobalt and manganese may be added.  In the examples, the catalyst is (a) the sulphonic acid produced in situ (by adding concentrated or fuming sulphonic acid to the phenol used in the reaction), (b) the sulphonic acid of, or one of, the phenols to be used in the reaction, or (c) p-tertiary amyl phenyl sulphonic acid, and in example (1) comparative tests are described using concentrated sulphonic acid or oxalic acid as the catalyst.  p-Tertiary-butyl phenol and formalin were condensed in the presence of catalysts (a) and (c), in (2) p-secondary butyl phenol and catalyst (a) were used, (3) p-tertiary amyl phenol and catalysts (a), (b) and (c) were used, (4) o-amyl phenol and catalyst (c), (5) p-cyclo hexyl phenol with catalyst (a) and (b), (6) p-phenyl phenol and catalyst (a), (7) o-phenyl-phenol with catalyst (a), (8) p-octyl phenol and catalyst (a), (9) nonyl phenol and (a), (10) a mixture of p-phenyl phenol and p-tertiary butyl phenol was reacted with formalin in presence of p-tert.-butyl phenol sulphonic acid, (11) phenol and p-tert.-amyl phenol were reacted with formalin in presence of the sulphonated amyl phenol, (12) a mixture of di-(4-hydroxyphenyl)-dimethyl methane and p-tert.-amyl phenol was condensed with formalin in the presence of p-tert.-amyl phenol sulphonic acid, (13) a mixture of p-cresol and p-tert.-amyl phenol was condensed with formalin in presence of the p-tert.-amyl phenol sulphonic acid, (14) p-tert.-butyl phenol was reacted with paraldehyde in presence of the phenol sulphonic acid.

Title: Improvements in carbon manifolding packs and apparatus for use therewith in typewriters
IPC: B41L1/16
Filed: 1928-06-05
Abstract: 302,864. Gill, H. A., (Burt Co., Ltd., F. N.). June 5, 1928. Ink-ribbon mechanism.-To facilitate the taking of manifold copies upon superposed record strips in a typewriter, a number of flexible carbon sheets are superposed and directly attached to each other at points spaced apart laterally on the sheets so as to permit the record strips to be threaded between them. A checking-bar is attached adjacent to the platen of the typewriter to prevent the carbon sheets being removed from the machine when the record strips are fed forward after portions thereof have been filled in. The carbon sheets 11 - - 14, Fig. 1, are attached to each other, preferably by stitching along lines 15, 16, the sheets being either of the same width throughout their length or, as shown, made wider at their points of attachment. The edges 22, Fig. 3, between which the record strips are threaded are preferably in overlapping relationship and folded upon themselves to facilitate the insertion of the record strips, the folded portion 23 of the carbon sheet 14 being, however, substantially as long as the other sheets. When the record strips are threaded between the carbons and arranged in the typewriter the extension 23 of the sheet 14 is passed around a thin flat bar 24, Figs. 6 and 9, of flexible metal which is supported by the platen carriage, at the delivery side of the platen. The bar 24 is mounted upon a rigid bar or plate 26 which keeps the outermost record strip closely against the bar 24. The bar 26 is removably fitted within slots in end brackets screwed upon the ends of the platen carriage, and carries a lug 33, Fig. 6, upon which one end of the bar 24 is pivoted, the other end of the latter bar being pivoted to an arm 34 provided with a lug 36 to receive a screw 38 secured within a lug on the bar 26. By adjusting the screw 38 the tension of the bar 24 may be varied. Fig. 9 shows the carbon sheets and record strips in position in a typewriter, the arrangement being such that, after entries have been made upon a set of forms in position on the platen 1, by rotating the operating-knob the filled-in forms are fed past the platen for detachment, movement of the carbon sheets being restrained by the checking-bar. The new set of forms now in superposed relation to the carbon sheets are brought, together with the carbons, into position for typing by rotating the platen in the requisite direction.
