Title: Improvements in or relating to ship propelling installations
IPC: B63H23/00
Filed: 1954-07-06
Abstract: 764,005. Propelling ships. AKT.-GES. WESER. July 6, 1954 [July 7, 1953], No. 19802/54. Class 114. [Also in Group XXVII] In a marine propulsion plant comprising a number of internal combustion engines which are connected via a common gearwheel drive and through the medium of fluid clutches to the propeller shaft a gearwheel is provided preferably with the interposition of a fluid clutch on each of the crank shafts of at least two of the internal combustion engines forming the plant these gearwheels being in permanent geared connection with each other and the crankshaft gearwheels being in permanent geared connection with two first pinions arranged to rotate in opposite directions to each other, the pinions being mounted each on an associated shaft which drives via a fluid clutch a second pinion meshing with a gearwheel on the propeller shaft the arrangement being such that when the plant is in operation, engagement of one of the latter fluid clutches causes the propeller shaft to be rotated in one direction and engagement of the other of these fluid clutches causes the propeller shaft to be rotated in the opposite direction. In Fig. 1, non- reversing internal combustion engines 1, 2, 3, 4 are connected to a propeller shaft 22 through the gearing shown and fluid clutches 11-14 and 17 and 18. For travel ahead the clutch 17 is filled and the clutch 18 is emptied and vice versa for travel astern. The plant can be doubled for craft having two screws. A slow speed stage is obtained by an electric motor 24 which is supplied for example, from a generator 23. In Fig. 2 the engines 2, 3 drive a gear wheel 21 on a propeller shaft 22 respectively through pinions 19, 20. The engines 1, 4 drive the wheel 21 through pinions 28, 29. As in Fig. 1 a very slow speed stage can be coupled with the plant and is supplied for example, from the generator 23. It is possible to couple with the plant other auxiliary power units which for example permit of a very slow speed stage and which can be either an internal combustion engine or an electrical driving unit. Also reference is made to interposition of additional fluid or mechanical clutches between the transmission gearing and the engines. The clutches 17 and 18 are of such size and design that the inner internal combustion engines can be placed so close to one another that only a catwork remains free between them without the clutches coming in contact with one another. In the space thereby gained at the outside of the engines auxiliary engines such as pumps or the like can be arranged.

Title: Improved labelling machine
IPC: B65C9/06
Filed: 1949-07-29
Abstract: 670,362. Labelling-machines. ARNOLD, J. C. (Pneumatic Scale Corporation, Ltd.). July 29, 1949, No. 19950/49. Class 73. A labelling-machine has a plurality of labelling mechanisms to which containers are successively presented by a conveyer means being provided to move the containers relative to the conveyer so that after receiving a label the labelled face is presented to a presser pad and a different face is presented to each labelling mechanism. Containers are transferred from a conveyer 52 by a spider 54 on to platforms 16 on which they are clamped by members 62, not shown. The platforms 16 are rotatably mounted in a plate 10 which is itself rotated about a shaft 12. Mutilated gear members 84 on the shaft of the platforms 16 have concave portions 82 and teeth 290 which co-operate with teeth 292, 302 on a stationary disc 86. Label applying mechanisms 18, 20 have suction pads 122 on arms 124 rotated about a shaft 134 in timed relation to the plate 10. The pads remove labels from a pile 150 in a container 158 and have adhesive applied by a pad 210, mechanism being provided to prevent operation of the pad 210 if a label is missing, and tack it to a container. Presser pads 55 on arms 294 mounted on a disc on the shaft 12 are reciprocated by a cam mechanism to press the labels after they pass from the labelling position. In operation, a container is passed from the conveyer 52 on to a platform 16 and clamped thereon. The platforms 16 rotating about the shaft 12 reach the labelling unit 18 where a label is tacked on one side by a pad 122, continued rotation of the platforms 16 engages one set of teeth 290 of the mutilated gear 84 with teeth 292 on the stationary disc 86 to turn the container 180 degrees about its axis until a concave portion 82 of the gear 84 faces the disc 86 and the tacked label faces the presser pads 55 which are then reciprocated against the container while it is opposite a supporting rail 300. The container is now in a position, as the pressure pads retract, to have a label applied to its opposite face by the mechanism 20, where a similar operation is performed before the container is replaced on the conveyer 52 by a spider 57.

Title: Improvements in or relating to photographic projectors
IPC: G03B21/53
Filed: 1964-05-14
Abstract: 1, 016, 567. Photo-electric control of automatic focussing. HONEYWELL Inc. May 14, 1964 [June 10, 1963], No. 20131/64. Heading G1A. [Also in Division G2]  A photographic transparency projector is automatically focused by forming an image on the transparency and forming a re-image of that image on photo-electric means sensitive to the position of the re-image simultaneously to adjust the projector lens and bring the re-image back to a datum position relative to the photo-electric means. An image of the filament of projector lamp 10 is formed via mirrors 27 and 30 by a lens 31 on the surface of the transparency 15. A lens 33 attached to the projector lens holder 21 forms the re-image at a point 34 between photo resistors 35 and 36. Movement of the transparency 15 owing to buckling shifts the re-image more on to one or other of the photo resistors 35, 36. This unbalances the bridge 40 and one or other of the triodes 41, 42 conducts to energize a corresponding relay 43, 44. Motor 26 moves the lens 33 to reposition the reimage at the point 34, and in so doing moves the projector lens 20 to maintain the projected image in focus. Initial manual focusing is by means of a friction wheel 22 which adjusts the position of the projector lens 20 relative to the lens carrier 21. In a modification, Fig. 2, (not shown) the lens 31 and not the lens 33 is attached to the projector lens carrier 21, and a lamp separate from the projection lamp is provided for the automatic focusing arrangement. To avoid interference between the projection light and the light used for automatic focusing, they may be made to have different spectral compositions e.g. by use of filters.
