Patent GB-656743-A (GB)
Title: Method for improving vulcanised rubber mixtures
IPC: C08K3/34
Filed: 1948-07-06
Abstract: A vulcanizable rubber mix comprises a filler which is either a clay naturally having a sufficiently high content of acidic organic extract as normally to prevent or substantially retard vulcanization, or a non-clay filler to which the said acidic organic extract has been added, together with a substance which counteracts said vulcanizing-impeding effect of the acid extract substance.  The acidic clays are usually grey or black and of the cryptocrystalline type such as halloysite.  The extract may be obtained by using a ketone such as methylisobutyl-ketone or diethyl-ketone.  The vulcanizing impeding effect of the acid may be counteracted by adding ammonium carbonate to the mix or by adding the acidic extract material in the form of an alkaline salt, amine salt, metal salt, or an ester or anhydride.  In addition to clays, the fillers may comprise carbon black, precipitated silica, magnesium carbonate and zinc oxide.  In examples the effect of adding such modified fillers to a standard mix comprising smoked sheets, zinc oxide, stearic acid, pine tar, sulphur, benzothiazyl disulphide, diphenyl guanidine, ammonium carbonate, and hexamethylene tetramine is illustrated. Specifications 616,069 and 640,169 are referred to.

Heading A1F. A combine harvester adapted for hillside operation comprises a table 18 including a platform 20 and an inclined body 19 so articulated that the platform is able to follow ground contours. Mounted on the platform are an auger and a finger-type beater 39 for crop conveyance to the elevator 40 mounted within the inclined body 19. The platform is articulated to the inclined body by means of a universal connection 42, allowing two degrees of rotational freedom, said connection being disposed on the axis of grain flow below the inclined body. In an embodiment, the connection comprises a spherical mounting 47 fixed on a cross-beam between beams 76, 77 and a ball support on the inclined body. Spring blocks 43 on both sides of the inclined body serve to balance most of the weight of the platform and a tension adjustment by means of bolts 59 allows optimum contour following by the shoes 69. Limiters 71, 72 disposed on the sides of the inclined body prevent rotation in the horizontal plane and comprise grooved guides 73 along which rollers fixed on members 76 move freely. The free ends of the members 76, 77 mount externally arranged rollers 80, 81 which slide inside flanged brackets 78 whose cross-section is such as to permit free movement of the members with the platform in the working position but to limit movement when the platform is in the transport position. Free movement of the platform is ensured by employing a drive mechanism comprising a telescopic cardan shaft.
