Title: Means to synchronize several internal combustion engines for ship propulsion driving a common propeller shaft
IPC: F02D25/02
Filed: 1951-01-03
Abstract: 686,634. Variable-speed gearing. SUBERKRUB, F. Jan. 3, 1951, No. 278/51. Class 80 (ii). [Also in Group XXVII] In variable-speed gearing for the propeller shaft of a ship driven by a number of internal combustion engines, the crank shafts are permanently geared together while running to ensure uniform ignition timing. In a reversing gear, Fig. 2, two motors 1 are connected through flange or claw couplings 3 to shafts 2 carrying pinions 8 which are permanently intergeared through pinions 10 and a gear 11, and the latter gear may be connected to the propeller shaft 7 by a friction clutch B to give reverse motion. For forward motion clutch B is disengaged and pinions 5 are clutched to shafts 2 to drive a gear 6 secured to the shaft 7. In gearing giving two forward speeds and reverse, Fig. 4, the two shafts 2 are intergeared through pinions 12 and a gear 13, and the latter may be clutched to the shaft 7 to give one forward speed. The second forward speed is obtained by clutching pinions 14, which engage a gear 15 secured to shaft 7, to the shafts 2. For reverse gear clutches A and D are disengaged and a clutch C is engaged to connect a pinion 18 meshing with the gear 13 to a shaft 16 carrying a pinion 17 which drives the gear 15 through a reversing pinion 19. The arrangement of Fig. 4 may be modified to give three forward speeds by omitting the pinion 19 and allowing the pinion 17 to mesh with the gear 15. Three forward speeds and reverse may be obtained by adding a shaft having two pinions, one fixed and the other clutched thereto, meshing with and interconnecting the gears 13 and 15. Where the power is too great to be transmitted by a clutch on the propeller shaft the gears 8, 12 may be clutched to the shafts 2 and an additional set of gears be provided to synchronise the motor shafts. The clutches may be of the laminar disc type and be housed within the gears.

Abstract: 621,107. Photographic and radiographic stereograms. DUDLEY, L. P. C. J. Jan. 4, 1945, No. 361. [Classes 97 (i), 98 (i) and 98 (ii)] A method of producing an auto-stereoscopic image with means for estimating depth, comprises juxtaposing or superposing a graticule or a projected image thereof and an autostereoscopic picture of a subject (or a projected image thereof), the graticule being an auto-stereoscopic picture of a depth indicator. The pictures which are X-ray or visual photographs may be parallax stereograms or parallax panoramagrams. The indicator structure may comprise evenly spaced rings 1 of metal wire, mounted on a frame 2 of material transparent to X-rays or to visible light, the rings being of increasing diameters. Alternatively the rings are of equal diameter and parallel with their centres on a line inclined to the base; or a conical helix of the wire may be mounted in the frame. Alternatively again, the helix may be of uniform diameter, mounted with its axis at an angle to the base. Further examples are of straight bars 7 of opaque material extending between straight or curved end-pieces 8 comprising a supporting frame of transparent material. Bars of opaque material may also be supported on a serpentine support. In all cases, the wires or bars may be embedded in a solid block of transparent material. A stereoscopic photograph or radiograph of the appropriate form is taken of the structure and the graticule so made is viewed along with the stereoscopic photograph or radiograph to be measured. This may be achieved by printing the record of the graticule onto the sensitive surface of the photograph or radiograph, or by viewing the two records together by means of a suitable grid; or an image of the graticule is projected on to a screen and viewed through a grid along with the photograph or radiograph or a projected image of the latter.

Title: Improvements in or relating to depth setting gear for submarine mines
IPC: F42B22/16
Filed: 1925-01-07
Abstract: 250,314. Vickers, Ltd., and Pratt, H. B. Jan. 7, 1925. Mines, marine. - Relates to automatically moored submarine mines of the kind provided with means for adjusting the length of the plummet line determining the depth of the mine. According to the invention, the unwinding of a predetermined length of plummet line is controlled by varying the starting position of contiguous members adapted to be angularly displaced relativelv to one another by the unwinding of the plummet line. Tn the form shown, when the mine is launched, the plummet A, Fig. 5. falls off, and its line B breaks a twine lashing a and, after taking up the initial slack, pays itself out from and rotates a drum C. A planet pinion E rotatable on a pin E<1>, Fig. 1, on the drum is carried round two toothed wheels F, G, one F fixed and the other G rotatable and formed with a few teeth more or less than the fixed wheel. Each revolution of the drum, therefore gives a small angular displacement to the wheel G, until a spring plunger J carried thereby snaps through a hole f in the wheel F and into a hole c in the drum, thereby locking the drum to the spindle H. An arm K on this spindle connected to a lever L by a block M thereupon shears a pin N and releases a slip hook P, freeing the mine from the sinker. And on a further slight rotation of the drum the lever K acting through a block S and a link R on a bell-crank lever u pulls a stop T from a ratchet T' on the mooring rope drum, allowing the mooring operation to take place. When the plummet touches bottom, the slack in the plummet line allows a spring V to restore the pawl T into engagement with the ratchet T to stop the mooring rope drum. The effective length of plummet line paid out of the drum C is determined by the initial angularposition of the spring plunger J relatively to the hole f. This is adjusted by pulling the pinion E out of mesh with the wheels F, G by means of a screw W, then turning the wheel G to the desired angle relatively to the wheel F, as indicated by a pointer on the wheel G against a. scale on the wheel F, and finally re-engaging the pinion E with the wheels F, G. This mechanism is protected by a detachable cover X.

[Classes 75 (ii) and 75 (iv)] In a vehicle lamp comprising a reflector built up from upper and lower half paraboloids which are so disposed with respect to the light source as to project a beam which is below a horizontal plane, visibility of the beam from aircraft is reduced by providing the lamp with a light filter having a high transmission for light of the shorter visible wavelengths which is liable to considerable scattering in the atmosphere (4000-5000 A.U.), and low transparency for light of longer wavelengths which is readily transmitted through the air (6000-7000 A.U.). The light source may comprise a short straight filament disposed horizontally along the axis of the lamp, and the lower half paraboloid may be arranged horizontally with its focus coincident with or in front of the front end of the filament, whilst the upper half paraboloid may be downwardly inclined so that its focus is substantially vertically below that of the lower half paraboloid. Alternatively, the upper half paraboloid may be arranged horizontally with its focus coincident with or to the rear of the rear end of the filament, whilst the lower half paraboloid may be downwardly inclined so that its focus is substantially vertically below that of the upper half paraboloid, or it may be displaced forwardly so that its focus coincides with or is in front of the front end of the filament. The Figure shows a combination of the last two arrangements. The upper and lower half paraboloids R1, R2 have foci F1, F2 respectively, a shield 5 which is dull black on all sides is provided on or near the bulb B to intercept forward and upward direct rays from the filament L, and a similar cowl C is fitted to the upper half of the lamp casing D. The front glass G may have a green tint to form the colour filter.
