Title: Improvements in or relating to projectiles
IPC: F42B10/16
Filed: 1945-12-14
Abstract: 602,219. Projectiles. STEVENS, A. H. (Aerial Products, Inc.). Dec. 14, 1945, No. 33874. [Class 9 (i)] A rocket projectile includes a cartridge casing which is inserted in the barrel of a launching pistol and retained the reinafter discharge and which contains a minor launching charge, the major charge being housed in a part of the projectile upon which slides a member which, in conjunction with a second member, supports some pivotally mounted guiding vanes, the latter being normally held in frictional contact with the inner wall of the cartridge casing but being moved towards the rear end of the projectile by friction on discharge and then opening out under spring action. In the construction shown, a projectile containing a parachute D and attached flare E, and also a rocket propulsion charge 45, is ejected from the barrel of a firearm by a charge 21 located in front of a detonator 24 in a cartridge case 14. The case has a groove 11, which is held by a suitable retainer in the gun on firing. The front of the charge 21 is a disc 25 which is perforated so that, on firing, the detonator will be able to ignite a projecting portion 50 of a fuze 47. The fuze is located in the charge 45 which is disposed between plugs 49, 52, in a casing 42. As shown, in Fig. 1, this casing is normally surrounded by four vanes 30 which are pivoted on rods 28 extending between a ring 27 and a sleeve 37. Springs 32 tend to swing the vanes outwards, that is to the operative position shown in Fig. 2. When the projectile is fired the frictional contact of the vanes with the interior well of the case 14 causes the vane structure to move to the rear as shown in Fig. 2, and when the projectile leaves the barrel the vanes are opened by their springs 32. The charge 21 is sufficient to send the projectile a distance of 25 to 50 feet, and at this stage the fuze 47 ignites the main propellant charge 45. When the projectile reaches a predetermined height, the charge 45 ignites a release charge 63 which, by pressure on a plug 64 expels the flare E and parachute D from a cylindrical container at the front of the projectile. The flare is ignited by the charge 45 through an axial hole 53. In Fig. 6 (not shown) a projectile is shown in which the vane and rocket structures are as in Fig. 1, but in which the head contains an explosive charge and has longitudinal and transverse grooves so that it may break into fragments when its nose strikes the target.

Title: Improvements in and relating to the recording and reproduction of sound
IPC: G11B15/50
Filed: 1932-12-02
Abstract: 399,043. Sound recording or reproducing apparatus. I. G. FARBENINDUSTRIE AKT. - GES., Frankfort on- Main, Germany. Dec. 2, 1932, No. 34166. Convention date, Dec. 2,1931. [Class 40 (ii).] Comprises means for recording a helical sound-record upon an endless record band or for reproducing from such a record, wherein the speed of the relative transverse movement between the recording or reproducing device and the band can be adjusted to suit the length of the band. The invention is shown in Fig. 1 as applied to mechanical recording or reproducing apparatus. A motor 3 drives, through a gear box 4 and shaft 5, a friction wheel 6 which serves to rotate a disc 7. Rotation of the disc 7 is transmitted through a worm 12 to a disc 13 on which is mounted frictionally a crank disc 14 connected by a crank 15 with a recording or reproducing device 10, so that the device 10 is moved across the width of the record band 2 as the latter travels in the direction of its length. The speed of movement of the device 10 is adjusted to suit the length of the record band by means of a pointer 9 movable over a dial 11 to adjust the friction roller 6 in position along a radius of the disc 7. A stop 15a, in the path of the crank pin on the disc 14, prevents further travel of the device 10 at the end of its transverse movement. In the modification shown by Fig. 2 the recording or reproducing device 1 is kept stationary while the record band 2 is moved transversely as well as longitudinally. For this purpose the record band support 16 is fixed to a slide 17 which carries a roller 19 bearing against one of a number of cams 20. The gradients of the cams are varied to suit different lengths of record band and the cam shaft can be displaced to bring either of the cams into contact with the roller 19. The invention may be applied to optical sound-recording or reproducing apparatus.

IPC: F16D43/26
Filed: 1965-08-11
Abstract: 1,099,137. Positive clutches; clutch combinations. ENGLISH NUMBERING MACHINES Ltd. July 28, 1966 [Aug. 11, 1965], No. 34302/65. Heading F2C. In a clutch means whereby a plurality of driven members are successively rotated during a predetermined number of revolutions of a driving member, an inwardly spring-biased pawl 15 pivoted on a driving member 31 is successively engageable with projections (43), (21) respectively of driven members 11, 20 under the control of a fixed cam 17, a non- rotatable but transversely movable cam 16, and a rotatable programme member 10. The driven members 11, 20 are respectively drivingly connected to an arm 1 and a sprocket wheel 8. The fixed cam 17 is supported via a bushing 36, on the driving member 31 and prevented from rotation by a fixed pin (37). The programme member 10 has two or more steps, such as (12), (13), (14) described, and a cam swell (18), and is rotatable on the bushing 36. The cam 16 is mounted on an eccentric boss 39 of the programme member 10 and has a radial slot (41) engaged by the fixed pin (37) so that rotation of the programme member effects transverse movement of the cam 6. In operation of the clutch means shown, first the driving member 31 is coupled to an outside drive by known means not described. The pawl 15, on rotation, engages successively the programme member step (12) and the projection (43) of the driven member 11. The programme member and the driven member 11 are then rotated until the pawl 15 is raised from the step (12) and the projection (43) by the fixed cam 17 after one revolution of the driving member 31. The driven member 11 is returned to its initial position by spring means not shown. On further rotation of the driving member 31, the pawl 15, leaving the swell of the fixed cam 17, successively engages the projection (21) of the driven member 20 and the programme member step (13). The programme member and the driven member 20 are then rotated. When the pawl 15 again reaches the fixed cam 17 it releases from the programme member step (13) but remains engaged with the projection (21) so that the driven member 20 continues to be rotated. When the pawl 15, on further rotation, engages the programme member step (14) the latter is again rotated and the eccentric boss 39 extends the swell of the cam 16 beyond that of the fixed cam 17 so that when the pawl 15 again approaches the fixed cam 17 it is released by the cam 16 from both the step (14) and the projection (21) so that the programme member 10 and the driven member 20 come to rest. Finally, the pawl 15, continuing rotation, is then lifted by the swell (18) of the programme member 10 to effect, by suitable means not described, disconnection of the driving member 31 from the outside drive. The programme member steps (12), (13), (14) are so disposed that the projection (43) of the driven member 11 is only engaged during the first revolution of the driving member.
