To provide a rising stiffness deflection characteristic in a torsionally resilient connection between the centre hub 1 and the outer plate 2 of a friction clutch plate for automotive transmissions, load transmitting rubber blocks 11 are moulded on four radial arms 5 of the hub 1, and bonded or adhered each side in pockets 9 formed with conically elongated clearance spaces 14 in outer plate flange members 7, so that the blocks 11 deflect initially in shear whilst heavier loads cause a ribbed end 16 of each block to move into increasing contact with the adjacent conical end of its pocket whereafter the blocks are also compressed and the stiffness considerably increased until finally, when the appropriate clearances 14 are absorbed, a near solid drive is effected with the rubber in volumetric compression. The rubber blocks may be attached direct to the side walls of the pockets 9 or, as shown, to plates 12 located therein by flanged edges 13. The arms are basically rectangular in cross-section and recessed each side to incease the surface area for rubber adhesion. The ratio of the thickness of the section to the axial width of the pockets is between 0.4 and 0.7.

Patent GB-911881-A (GB)
Title: Manufacture of quinacridone
IPC: C09B48/00
Filed: 1959-02-03
Abstract: Linear quinacridone is made by oxidising 6:13-dihydroquinacridone in a medium comprising water, an alkali and a water-miscible polar organic solvent stable therein, the relative proportions of the medium being in parts by weight 20 to 120 of alkali per 100 of water and at least 5 of alkali per 100 of total liquid and the amount of organic solvent being at least as much as the water, such as to effect at least partial solution of the dihydroquinacridone. Solvents specified are methanol, ethanol, n-propanol, isopropanol, isobutanol, glycerol, ethylene glycol and the monomethyl and monoethyl ethers thereof, ethanolamine, dioxan, ethylene diamine, pyridine, quinoline and dimethyl sulfoxide.  Oxidising agents mentioned are sodium nitrobenzene-m-sulphonate and sodium polysulphide.  The product is obtained predominantly in the b -crystal phase when the solubility of the dihydroquinacridone in the medium is low, or when the proportion of alkali in the medium is sufficient to precipitate sodium quinacridone and the latter is rapidly hydrolysed with water.  The g -crystal phase is predominantly obtained when the solubility of the dihydroquinacridone in the medium is increased, e.g. by increasing the proportion of the solvent or by using good solvents for dihydroquinacridone such as pyridine or mixtures thereof with alcohols or quinoline.  The g -phase may also be obtained by digesting the b -phase in an alkali/solvent/water medium of sufficient solvent power or by seeding with g -phase crystals an oxidising mixture which would otherwise produce the b -phase.  Examples are given.
