Title: Keratinolytic enzymes
IPC: C12N9/62
Filed: 1958-11-25
Abstract: Keratinolytic enzymes are produced by cultivating a keratinase-producing strain of Aspergillus flavus, e.g. ATCC 13003 or Aspergillus niger, e.g. ATCC 13004, in an aqueous nutrient medium containing a source of protein rich in sulphur containing amino acids and disulphide bonds and inorganic salts.  Suitable proteins are keratins, e.g. hair, feathers, wool, horn meal, hoof meal, horn-hoof meal and partially degraded wool, i.e. an alkali degradation product of wool soluble to the extent of 10% in water and containing 15.3% nitrogen, 4.1% sulphur, 7.0% moisture and 0.5% ash.  Suitable inorganic salts are sodium chloride, magnesium sulphate, calcium chloride, ferrous sulphate, zinc sulphate, potassium acid phosphate and dibasic potassium phosphate.  In the example, the culture medium is an aqueous solution of all the above specified salts plus partially degraded wool.  The pH is 5 to 9 and especially 6.5 to 7.5. The enzyme is isolated from the clarified broth by (a) adsorption and (b) precipitation.

Title: Percussion mechanism for rocket or other projectile launching weapons
IPC: F41A19/52
Filed: 1957-12-09
Abstract: 832,436. Firing mechanisms for rocket launchers. ANSTALT FUR DIE ENTWICKLUNG VON ERFINDUNGEN UND GEWERBLICHEN ANWENDUNGEN ENERGA. Dec. 9, 1957 [Jan. 18, 1957], No. 38252/57. Class 92 The firing mechanism of a rocket launching weapon comprises a striker 16 on a hammer 15 pivoted at 22 and swung rearwardly after firing by the propulsive gases of the rocket against the action of a percussion spring 26, the hammer being held in the cocked position by a cocking sear 17 and a safety sear 18. A lock 20 pivoted at 40 has a latch portion 21 projecting into the barrel for securing the rocket in the barrel and is urged into this position by a spring 46. Withdrawal of the lock 20 from the barrel is effected either manually or automatically, on firing, by the hammer as shown in Fig. 5 or by the introduction of a rocket into the barrel, the arrangement being such that withdrawal of the lock brings the safety sear 18 into its active position. By operating a lever F the safety sear 18 is moved into inactive position shown in Fig. 4 and a nose 35 of this sear engages a pawl 36 on one end of a bell-crank lever 19 pivoted at 40 and having its other end 41 engaging in a recess 42 in the lock 20. On pressing the trigger 2, Fig. 2 (not shown) a transmission rod 11 moves an arm 32 of the cocking sear 17 to release the hammer 15 and a recess 23 on the hamber engages a finger 25 of the lock 20 to withdraw it from the barrel and free the rocket. Such withdrawal moves the arm 41 on the lever 19 downwardly and disengages the pawl 36 from the nose 35 of the sear 18 which comes into its active position and together with the sear 17 re-engage with the hammer. If a rocket is being inserted in the barrel when the mechanism is cocked, the downward movement of the lock 20 similarly causes the safety sear 18 to reengage with the hammer. To extract a rocket already put into position in the barrel, a lever S solid with the lever 19 is moved to move the arm 41 and hence the lock 20 downwardly to free the rocket. This again results in bringing the sear 18 into active position if it were not there previously. Finally, if after cocking the mechanism by actuating the lever F, it is desired to re-secure it, the lever S is operated to such an extent that the pawl 36 is freed from the nose 35 but the latch 21 of the lock 20 is not lowered, this being possible by means of the clearance available to the arm 41 in the recess 42.
Patent GB-344099-A (GB)
Title: Improvements in folded stationery adapted to be bound in book form
IPC: B41L1/32
Filed: 1929-12-16
Abstract: 344,099. Manuscript books. POWER, R. F., 18, Chesterford Gardens, Hampstead, London. Dec. 16,1929, No. 38550. [Class 16.] In a record strip adapted to be folded in zig-zag fashion to form sheets, marginal projections are provided by which the folded sheets may be secured in a binder or book. A long strip of paper 1, Fig. 4, is creased alternately at 2, 3 to form pages 4, with shoulders 5, 6 giving a border 7 to each longitudinal edge of the strip. The binding elements are formed by slitting the strip 1 longitudinally at intervals, as shown at 8. The separate portions of the border 7 may be laterally creased at 9 so that on folding the main strip in zig-zag fashion, portions of the separate border 7 form projecting lugs 10, Fig. 3, at each side of one edge of the folded strip 1, which may be perforated as at 11 for filing in a binder or cover. In a modification the borders are not continuous for the whole length of the strip, but are only located adjacent each alternate fold so that lugs of only single thickness are provided. In the modification shown in Fig. 6, the borders are cut away at 21 and folded back and secured by adhesive on the portion 20, thus making alternate sheets 4 of full width, and intermediate sheets somewhat narrower for a portion of their length. Semi-circular recesses 23 may be provided on the inside edges of the lugs 20 for engagement with movable filing-bars. In the modification shown in Fig. 7, one of each pair of binding lugs project from alternate sheets 4, the lug 26 being formed from a simple slit which leaves a portion projecting from below the crease 2 when the strip is folded, and the lug 27 projecting from above the crease 2. Where single binding projections are employed, packing blocks or other spacing means may be associated with the binder so as to ensure that the covers lie flush when the folded strip is bound. By extending the longitudinal slits within the area of the pages 4 the manipulation of the folded strip in book form is facilitated. The strip 1 may be in the form of a roll before being printed, and then the various points at which the folds are to occur are creased or perforated, the required apertures or slots being also provided in the binding projections during manufacture.

Abstract: 917,305. Small parcels transferring apparatus. FISCHER, E., and JENSSEN, H. A. W. G., [trading as SCHMIDT SOHNE, C. AUG.]. Nov. 10, 1960 [Nov. 11, 1959], No. 38618/60. Class 78 (1). A container arriving at a station 1 under the action of suction in a conduit 1 is braked by the action of a reversal of air flow in a section 7 of conduit 1. The container actuates a switch 8 to energize a relay 10. This results in the closing of a solenoid-operated valve 13 and the opening of a valve 14. The former cuts off the suction from the blower 4, and the latter opens the conduit section 7 to atmosphere. Suction in the main section of conduit 1 is maintained by means of a by-pass 5. In a modification, the by-pass 5 is normally closed by a valve 18 which is opened when the switch 8 is closed.
