Machine guns.-A modification of the screw mechanism described in the parent Specification for operating the sliding bolt-sleeve of a shortrecoil gun, comprises a fixed screw-threaded stem on which is mounted a rotatable sleeve adapted to be reciprocated by the barrel and formed with a helical cam which operates the bolt-sleeve. As shown, a fixed non-rotatable stem 1 is formed with steep pitch screw threads engaged by corresponding internal threads on a sleeve 11 adapted to be driven back, and consequently rotated, by the barrel. The sleeve has an external cam 12 adapted to engage a projection 14 on the boltsleeve so that its rotation effects relative displacement of the bolt-sleeve. For effecting the axial movement of the sleeve 11, the barrel extension 19 is formed with a projection 21 adapted to engage a circumferential groove 20 at the front of the sleeve, the front wall 23 of this groove being formed with a longitudinal slot 24 into which the projection 21 passes when the barrel is in its forward position, as shown in Fig. 1, the sleeve being then locked against rotation. A longitudinal slot 13 is formed through the cam 12 and rear flange to allow of the return movement of the projection 14 on the bolt-sleeve. The stem 1 and sleeve 11 are mounted in a cylindrical chamber 2 in a detachable cover 3 of the breech casing.

Abstract: 1,157,404. Treatment of furs. ROHM & HAAS, G.m.b.H. Feb. 15, 1968 [Feb. 17, 1967], No.7481/68. Heading C6C. In a process for loosening the structure and thus improving the pliability of conventionally dressed furs, such as lamb and calf furs, they are treated with at least one proteolytic enzyme in the presence of water. The treatment may be effected at temperatures between 40 and 50 C., and between 0À5 and 3À0% of proteolytic enzyme (s), based on the weight of dressed furs, may be used. The treatment may be carried out in the presence of at least one reducing agent, e.g. selected from; sodium bisulphite, sodium sulphite and sodium dithionite. The proteolytic enzyme may be a fungal protease, e.g. obtained by culturing Aspergillus oryzae or Aspergillus flavus, and the treatment may then be effected at pH 4À5 to 6. Alternatively, the proteolytic enzyme may be a bacterial protease, preferably obtained from a strain of Bacillus subtilis, and the treatment may then be effected at pH 5 to 7. As a further alternative, the proteolytic enzyme may be a pancreas tryptase, and the treatment may then be effected at a pH above 6À5. According to Example 3, Persian lamb furs are dressed and finished in a conventional liquor, and then treated with an aqueous liquor containing pancreas tryptase and a fungal protease, a dye and a fat-liquoring agent, and the treated furs are finally washed. The proteolytic enzyme may be added to furs in an aqueous fat-liquor, immediately after the furs have become fat-liquored. The dressed furs are preferably treated according to the invention after they have been finished, e.g. matched, bleached or bated with metal salts.
