Title: Improvements in or relating to torpedoes or the like
IPC: C11D3/066
Filed: 1934-03-17
Abstract: 435,549. Submarines. KONSTANTINOFF, J., 11<bis>, Rue Alfred Roll, Paris. March 17, 1934, No. 8457. Convention date, March 18, 1933. [Class 113 (ii)] [See also Group XXI] To prevent the visible wake of a torpedo, the rear end of the propeller shaft 1 thereof is fitted with a device comprising a hollow shaft 2 presenting in serise a balance chamber 10, a Venturi tube 13, and a chamber 15 which houses a runner 18. The shaft is surrounded by a shell 6 having a vacuum chamber 36 which receives the discharge from the chamber 15 and is fitted with injectors 38 which deliver water thereinto. The vacuum chamber communicates with an atomising chamber 39 from which discharge is effected to the exterior by way of a spring-loaded non-return valve 23 and a stirring chamber 28. In the construction shown, the shell 6 is screw-threaded to engage a turbine rotor 5 to which it is locked by screws 8, the rotor 5 together with the shaft 2 being locked to the propeller shaft 1 by bolts 4. The balance chamber 10 has fins 11 and openings 12 so devised as to permit the escape of some of the exhaust gases and thus to prevent the occurrence of back-pressure on the torpedo motor. The tube 13 is secured to the chamber 10 by screws 14 and is adapted to double the speed of the gas which impinges on the runner and causes it to rotate in the reverse direction to the shafts. The gas then enters under high pressure into an annular pocket 43 and thence issues through openings 16 to create the vacuum in the chamber 36 whence it passes to the atomizing chamber 39. The latter is fitted with blades 35 upon which the gases and water impinge in such manner as to supply further power in driving the shaft 1. The stirring chamber 28 into which the mist, created in the atomizing chamber, is then discharged houses two water directors 29, 32. The director 29 is loosely mounted upon a collar 27 secured to a stem 22 of a plug 19 which is screwed into the end of the chamber 15. This director is fitted with adjustable studs 21 which determine the lift of the valve 23, and with vanes 30 which prevent the director from revolving with the other parts of the device. Water enters this director through openings 31 and into the director 32 through openings 33. The mist passes between the directors where it is thoroughly mixed with water by vanes 34. Vanes 7 serve to promote the flow of water along the shell. In a modification the rotor is screwed directly into a boss on the propeller and in another construction the propeller blade and rotor are cast together, the rotor being provided with blades. The Specification as open to inspection under Sect. 91 states also that the device may be used in conjunction with the Diesel-electric generators employed in submarines for charging the storage batteries. This subject-matter does not appear in the Specification as accepted.

Abstract: 700,295. Thread tensioning devices. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 26, 1951 [April 5, 1950], No. 8614/50. Class 120(2) [Also in Group XVI] A tensioning mechanism for filamentary or strip material, comprises a pulley, spool or bobbin adapted to be rotated in one sense by the said material moving in engagement therewith, a shaft on which the pulley, Spool or bobbin is fixedly mounted and a helical braking spring wound on, the shaft, the direction of winding being such that the shaft, as it rotates in the one sense, assists the spring to expand diametrically, one end of the spring being secured in position, and the other end comprising a tongue arranged to bear upon the filamentary or strip material, the arrangement being such that the spring tends to expand diametrically when the tension in the material increases. As shown, 1 is a shaft having a pulley 2 fixedly mounted thereon and 3 is a helical spring encircling the said shaft, one of the ends 4 of the spring being secured by a clamp (not shown) to some fixed Dart of the device. The other end 5 of the spring is in the form of a tongue and 'carries a light pulley 6. Thread 7 extends around pulleys 2 and 6 and the arrangement is such that an increase in the tension in thread 7 causes the spring 3 to expand diametrically to reduce the braking effect on the shaft 1 and a decrease in tension allows the spring 3 to contract and increase the braking effect. The end 5 of the helical spring is biased by a further spring 8. For tensioning strip materials the pulleys 2 and 6 may be replaced by rollers and the spring 3 may be duplicated on the other side of the pulley or roller the respective ends 4 and 5 being joined by cross-members if desired.

Filed: 1926-03-30
Abstract: 250,238. Dubilier Condenser Co. (1925), Ltd., (Assignees of Jacobson, M.). March 30, 1925, [Convention date]. Condensers. - A multiple circuit condenser comprises sets of rotor plates, the sets of plates being mutually insulated and having a separate contact, and a set of stator common to all the rotor plates and common operating means for all the rotor plates. In the form shown in Figs. 1 and 2, the metal end plates 12, 13 are connected by spacing posts 14 and support a control shaft 15 and rotor spindles 16 - - 18 which are operated from the shaft 15 by means of a central spur gear 22 and gears 23 - - 25. The diameter of the gear 22 is half that of the others, so that rotation of the spindles through 180‹ produces 360‹ rotation of the knob and pointer. The spindles 16 - - 18 carry the rotor plate sets 26 - - 28 which are placed intermediate a set of stator plates 29 of triangular form mounted on posts 14 by means either of spacers or also by soldering. To insulate the stator from the rotor the gear 22 may be of rubber or the like and the spindles 16 - - 18 may be mounted in bushings 39 of hard rubber. For connecting the rotors in circuit, springs 30 are adapted to bear on the spindles and are mounted on " Bakelite " blocks 31 and provided with flanges 34 to prevent their turning on the blocks. In the modification shown in Figs. 3 and 4, the gear 22 is replaced by right-handed worms 52 and a left-handed worm 52a secured to the control shaft 45 and engaging worm wheels 53 - - 55 on spindles 46 - - 48 carrying the rotor plate sets 56 - - 58. The latter co-operata with a common stator plate set 59 secured to posts 44 and connecting end plates 42 in which the spindles 46 - - 48 are pivoted. The shaft 45 passes through a sleeve 43 which is journaled in a bracket 60 and carries a pointer 50. Motion is transmitted to this sleeve and pointer from the control shaft by means of bevel gears 64, 65 and spur gears 62, 63, the latter being on the sleeve 43. The pointer 50 may be then geared to rotate with the same velocity as the spindles 46 - - 48 while the pointer 49 may have the velocity of the shaft 45. The pointer 46 will thus indicate the relative position of the rotor sets and the pointer 50 their angular displacement. Fig. 5 shows a form of rotor plate 66 provided with a number of holes 67, the number gradually increasing towards one end to give a straight line wave-length or frequency characteristic or any other desired characteristic, and the stator plates may also be apertured.
