In further modifications, the shaft for driving the slide-block is separate from the shaft 4 operating the clamping mechanism.
Patent GB-427332-A (GB)
Title: Process for the manufacture of new dyestuffs of the anthraquinone series
IPC: C09B1/34
Filed: 1933-10-20
Abstract: Anthraquinone dyes are prepared by causing compounds of the formula NH2--RSOR<1> wherein R stands for aryl which may be substituted, R<1> for alkyl which may be substituted and the --SOR<1> groups are in m- or p-position to the amino group, to react upon anthraquinone compounds containing at least one negative substituent capable of being replaced by amino radicles (such as halogen or hydroxy groups), and introducing a sulpho group by the action of fuming sulphuric or chlorsulphonic acid, or, if the product still contains halogen atoms, by the action of a neutral alkali metal sulphite, the introduction of the substituents being performed in any sequence.  Alternatively in place of the group --NH--R--SOR<1> the corresponding group --NH--R--S--R<1> is first introduced, and the sulphide group oxidized to sulphoxide simultaneously with or subsequent to the introduction of the sulphonic acid group by causing oxidizing agents, such as hydrogen peroxide or lead tetracetate to react upon the same.  The products are water soluble blue to green dyes possessing good levelling capacity.  In examples: (1) 1 - amino - 4 - bromanthraquinone-2-sulphonic acid is condensed with 4-aminophenyl-methylsulphoxide to give a product dyeing wool blue shades; using 4 - methyl - 3 - aminophenylmethylsulphoxide instead or 4 - aminophenylethylsulphoxide similar dyes are obtained; (2) 1-amino-2,4 dibromanthraquinone is condensed with 4-aminophenylmethylsulphide whereby the 4-bromo atom is replaced by a 4<1>-methylmercaptoanilido residue; treatment of this product with sodium sulphide in aqueous phenol-pyridine or aqueous alcohol medium to replace the 2-bromo atom by a sulpho group and oxidation with peroxide or lead tetracetate in acetic acid or pyridine (these operations being performed in either sequence) yields the desired product of (1); (3) leuco quinizarin-6-sulphonic acid is condensed with 4 - methyl - 3 - aminophenyl - methylsulphoxide in presence of boric acid; wool is dyed green shades; the same product is derived by condensing the sulphoquinizarin with 4-aminophenylmethylsulphide, condensation being carried out by reduction of the quinizarin derivative with zinc dust, followed by oxidation of the sulphide derivative with aqueous peroxide; (4) quinizarin admixed with leuco quinizarin is condensed with 4-aminophenylmethylsulphide, the product sulphonated and then oxidized in aqueous pyridine.  The Specification as open to inspection under Sect. 91 relates to the manufacture by methods known per se of anthraquinone compounds containing at least once as substituents the group --NH--R--SO--R<1>, wherein R stands for aryl which may be substituted, R<1> for a hydrocarbon radicle (such as alkyl, aryl, aralkyl, or hydroaryl) and the sulphonic acid group, and reference is made to the use of 4-aminodiphenylsulphoxide as a condensing agent.  This subject-matter does not appear in the Specification as accepted.

Abstract: 280,215. Budd Wheel Co., (Assignees of Hughes, J. W.). Nov. 3, 1926, [Convention date]. Rolling discs.-Tapered wheel discs are rolled from square &c. blanks a by rolling along substantially radial lines first in one direction to give the shape as shown in Fig. 4, and then in the opposite direction to give an approximately circular shape. The apparatus comprises two rolling stations and one feeding station arranged at 120‹ on a turntable. A single square blank or a pack is placed with its corners fitting into recesses in a platen 22 and the turntable 14 is rotated 120‹ to bring- the blank under a conical roll 10 or station B. The whole turntable is then raised by the reciprocation of a wedge 36 to bring the blank into contact with the continuously driven roll 10. When rolled the turntable is lowered and rotated by gearing through 120‹ to bring the blank under the oppositely rotated roll at station C, while fresh blanks come under the roll at station B. The blanks are ejected by a raised portion in a cam groove 39 which pushes up the shaft 28 and so raises the platen, lifting the blank free of the recesses in the plate 22.

Title: Polymers of conjugated dienes and their preparation
IPC: C08F36/04
Filed: 1965-07-12
Abstract: One or more conjugated dienes or a mixture of at least one conjugated diene and at least one aromatic vinyl compound are polymerized in solution in a hydrocarbon solvent in the presence of a catalytic system comprising an organic lithium compound and an effective amount of a catalytic adjuvant which is an organic mono- or poly-halide having at least one mobile halogen atom which is associated with a carbon atom located alpha to either a double bond or an aromatic nucleus, the ratio of the total number of halogen atoms to the total number of lithium atoms being from 0.1 to 1.0 whereby the polymer or copolymer product has an increased molecular weight as compared with a polymerization in the absence of the adjuvant.  The preferred products have an inherent viscosity of more than 2.5 and have more than 50% of the polymer structure in the cis 1-4 configuration. Specified lithium compounds are n-butyl lithium, dilithium naphthalene, and 1,4-dilithium butane while 1,4 - diodo - 2 - butene, allyl bromide, allyl chloride, allyl iodide, 1 - bromo - 2 - butene, 1,4-dibromo-2-butene, benzyl chloride and 3,4-dibromo - 1 - butene are specified adjuvants. The adjuvants may be prepared in situ, e.g. by adding elemental halogen to a solution of a conjugated diene, as in the preparation of 1,4-diodo-2-butene from iodine and 1,3-butadiene, or by the addition of such saturated halogen compounds as tertiary alkyl halides and alkylene halides (which release halogen) thereto.  The polymerization may be carried out in the presence of 0.03 to 0.12 molar equivalent of lithium per 100 mols of monomer, the ratio of the total number of halogen atoms to the total number of lithium atoms being from 0.1 to 0.7. Examples are given of the polymerization of butadiene, isoprene, and butadienestyrene mixtures.  Those products having an inherent viscosity above 3 may be blended with low molecular weight components having an inherent viscosity of from 0.5 to 1.5 to produce a mixture of inherent viscosity from 2 to 3, or also, in the case of the copolymers, of inherent viscosity above 2.2.  The mixtures may be compounded with the usual additives and vulcanized.
