Title: Improvements in or relating to hydraulic internal reaction propulsion for ships
IPC: B63H11/12
Filed: 1926-12-03
Abstract: 262,467. Angelini, O. Dec. 3, 1925, [Convention date]. Propelling by water jets.-Water which flows into a tube 1, Fig. 1, past a non-return flap 18 is expelled by compressed air through a small opening 19 in the flap, the issuing jet being used to propel the ship containing the tube. Directly connected pistons 4, 5 are reciprocated by power resulting from a two-stroke internal combustion action in the cylinders 2, 3, and on the inner side act as compressors drawing air from a reservoir 7 through suction valves 23 and delivering through valves 24 into a receiver 6. Air from the reeciver 6 is used to drive a gear wheel motor 8 on the shaft of which is an eccentric 14 the rod of which moves a valve 15 for opening the receiver 6 to the tube 1 and blowing water out of the tube and also moves valves 16, 17 for allowing the air to go back to the receiver 7 when water is to flow into the tube. The valve " period " is controlled by the speed of the motor 8 which is regulated by the admission valve 9. A drain cock 40 and suction valve 38 are fitted to the reservoir 7. More than one flap 18 may be fitted to each tube, and more than one tube may be installed in a ship. In a modification, the rod 26, Fig. 21, connecting the pistons carries a cam 32 which controls the valve 34 in the fuel supply pipe to the nozzle 30 and also controls the valve 33 admitting air to the inlet 29 surrounding the nozzle.

A polycaproamide polymer having an intrinsic viscosity not less than 1À20, as determined in solution in m-cresol, is spun at a speed of at least 350 m./min., and the extruded filaments, which have a birefringence of at least 0À015, and preferably of from 0À015 to 0À035, are drawn in two or more steps, the draw ratio of the first stretching step for filaments having a birefringence of 0À015 being from 3À5 to 4, and that for filaments having a birefringence of 0À035 and above being from 2À5 to 3À5, the draw ratio of the first stretching step for filaments having a birefringence of 0À015 to 0À035 being obtained by interpolation from the accompanying diagram (Fig. 1). The starting yarn may be obtained by spinning a polymer having an intrinsic viscosity of 1À20 to 1À50 at a speed of 400 m./min. to 800 m./min., Figs. 2 and 3 (not shown), illustrate stretching apparatus. In Fig. 2, the first stage stretching is effected between rolls 11 and 19, suitably heated to 150‹ to 200‹ C. and especially to 170-185‹ C., and second stage stretching between rolls 19 and 21, roll 19 being heated. In Fig. 3, roll 19 is not heated but the threadline is heated by passage through heater 20, suitably heated to the same temperature as roll 19 in Fig. 2. Snubbing pins may be inserted between rolls 11 and 19, or rolls 19 and 21, if desired, and said pins may be held at room temperature or heated to 40-75‹ C. and preferably to above 60‹ C.

Printing-plates such as 4, 4<SP>1</SP>, Fig. 7, are secured to a printing-cylinder 1 by means of clamping-hooks 33 and register hooks 14 engaging recesses in the underside of the plates near the two straight edges of each plate. In the form described, four pairs of semi-cylindrical plates each having four recesses near each edge are secured to the cylinder. Each clamping hook assembly comprises a hook member 33 and an actuator arm 34 held together, with the surface 38 of the arm 34 in contact with the hook member 33 and a portion 39 of the arm bearing in a groove 40 of the member 33, by means of springs 35, a bolt 36 and a nut 37. On counter-clockwise rotation of a look-up shaft 46, a cam surface 48 thereof first pivots the hook assembly to move the hooks into the recesses 8; the assembly being provided with lugs 45 rotatably received in clamp supports, and then forces the face 38 off the member 33 so that the hooks are held resiliently in the recesses by the force of the springs 35. Each pair of register hooks 14, Figs. 7 and 9, which engage in recesses 8 near the opposite edge of the plate, is carried in a register support member 52 so as to be rotatable about an axis radial to the cylinder. The hooks are inserted in the member 52 at right-angles to their operative positions through bores 57 having extensions 58 to accommodate lips 51 on the hooks, and on rotation into operative position cannot be removed. Each hook is acted upon by two spring- urged plugs 62, one on either side of its axis of rotation, so that the hooks are resiliently mounted to maintain uniform pressure along the length of the slots. The member 52 is also provided with a cam surface engaging a corresponding surface on a register adjustment bar 55<SP>1</SP>, which is movable axially of the cylinder to move the member 52 circumferentially, so far as permitted by a groove 54 in the cylinder, for circumferential adjustment of registry of the plate. Each plate is provided with means for axial adjustment thereof on the cylinder, comprising a screw 11, Fig. 2, carrying at each end a disc 12 protruding from the cylinder surface, the discs abutting the curved edges of the plate near the straight edge engaged by the register hooks. Each disc is provided with holes 25 for engagement by a wrench to rotate the screw for said axial adjustment. Inadvertent rotation of the screw is prevented by detent means comprising grooves 23 in an extension of the screw engaged by spring-pressed balls 19.
