Title: Improvements relating to the Construction of Ships' Hulls
IPC: B63B9/00
Filed: 1966-08-11
Abstract: 1,174,604. Building and enlarging ship's hulls. SWAN HUNTER GROUP Ltd., and FREDRICK TAYLOR. 17 March, 1967 [11 Aug., 1966], No. 36018/66. Heading B7S. [Also in Division E1] A method of constructing a ship's hull includes the steps of launching two prefabricated portions H1, H2, Fig. 3, of the hull and effecting permanent connection thereof to each other by, e.g., welding, while they are afloat and temporarily held together by, e.g., external connecting-means (not shown) or bolting internal ribs R1, R2 in one portion to corresponding ribs in the other portion, external connecting- operations on the plates below the waterline L being performed within a caisson 10 that is temporarily placed adjacent said portions in the region of the joint therebetween. The portion H1 may be constructed so that it initially includes the adjacent end section of the portion H2, which section is delimitated by a plane C, this section being severed by, e.g., flame cutting, from the portion H1 before this portion is launched, whereafter the remainder of the portion H2 is constructed such that it is incorporated with said section. This procedure ensures that a satisfactory joint is obtained when the two portions are united in the manner aforesaid. The ribs R1, R2 in said section and the corresponding ones in the portion H1 may be either rendered integral with each other and severed by flame cutting before this portion is launched or provisionally attached to each other by bolts E, Fig. 4, engaging with flanges F on the ribs, which are spaced apart by a packing strip D to provide compensation for loss of material when the plates are cut during severance of the end section, the packing strip being omitted when the two portions are united. Alternatively, the ribs R1, R2 are rendered such that a gap exists between the plates on the adjacent ends of the two portions of the hull when they are brought together, this gap being subsequently bridged by lodging additional plates between said ends and attaching these plates by welding. The hull may comprise more than two prefabricated portions and the method may be employed in effecting enlargement of a hull by insertion of at least one prefabricated portion between the existing portions of the hull. The caisson 10 has the configuration of an open channel and is furnished with upwardlyextending sections at its ends, flanged plates A being provisionally fixed to the sides of each portion of the hull to facilitate sealing of the lateral edges of said sections. Sealing strips 22 are lodged in the edges of the caisson and buoyancy chambers (see Division E1) are formed in the caisson so that it can be conveniently manoeuvred and held against the portions of the hull while water in a working space or gallery 14 is discharged.

Abstract: 1462809 Cameras FUJI PHOTO FILM CO Ltd 16 Aug 1974 [17 Aug 1973] 36266/74 Heading G2A In a camera having a chamber 5 for a film supply spool and a chamber 6 for a take-up spool, and a passageway 10 between the two, the camera body is formed with at least one eave portion 14 which projects over the junction of the passageway with one of the chambers to restrain the film from lateral movement. As shown, there are in fact two such eaves 14, 15, one at each end of the passageway. When the top cover of the camera is removed, it is seen as in Fig. 3. To load the camera, one end of a supply reel of unexposed film on spool 7 is unwound sufficiently to be attached to spool 8, and the two spools are dropped into their respective chambers, the length of film 13 between them being slotted into the passageway. (The walls of the passageway are formed by an inner wall 9 of the camera and a rear wall not seen in Fig. 3.) The length of film 13 is initially slack enough to pass round the eaves 14, 15, but after spool 8 has been rotated sufficiently to take up the slack, the film is now held beneath the eaves, as seen in Fig. 3, and so restrained from any lateral movement parallel to the axes of the spools. A restraining and guiding spring clip is provided round the film on spool 7 to hold the film firmly, one end 16b of the clip guiding the unwinding film so that it always remains under the eave 14. Another spring clip 17 holds the film firmly as it is wound on to spool 8.

Abstract: 889,712. Dispensing sheet or ribbon-like material. JONES & CO. (ENGINEERING) Ltd., SAMUEL, and PHILLIPS, C. H. Oct. 18, 1960 [Oct. 26, 1959], No. 36275/59. Class 18. Gummed tape or sheet material is fed from a roll (not shown) by means of a driven roller (not shown) with which the tape is maintained in frictional engagement by a spring-loaded knurled idler wheel 1, the tape passing over a fixed anvil block 13 and beneath a cutter 2, and the idler roller and cutter blade being actuated by a dual toggle linkage 6. . . 8. The idler wheel shaft 3 rotates freely in a carriage 4 which is pivoted to lugs on a casing 12, and the cutter blade 2 is fixed to a similarly pivoted carriage 5. The toggle linkage comprises a first arm 6 pivoted at its lower end to the casing 12, a second arm 7 pivoted to the upper end of the first arm and pivoted to the cutter blade carriage 5, and a third arm 8 also pivoted to the upper end of the first arm and pivoted to the idler wheel carriage 4. Operation of a solenoid 11 causes a lever 10 to actuate rod 9 and shift the linkage in a sense tending to bring the second arm out of alignment with the first arm and tending to bring the third arm into alignment with the first arm. A rocking movement is thereby imparted to both carriages, a relatively slow powerful movement of the cutter blade carriage 5 causing the blade to sever the tape against the fixed knife 13, and a relatively rapid movement of the idler wheel carriage 4 lifting the idler 1 out of contact with the tape so that feed ceases.

Abstract: 802,478. Fluid-pressure servomotor-control systems. SOC. FRANCAISE DES REGULATEURS UNIVERSELS ARCA. Dec. 21, 1955 [Dec. 22, 1954], No. 36647/55. Class 135. A pneumatic control system for regulating a variable condition, e.g. temperature, in which the regulator is controlled by a pressure modulated by movement of a baffle relatively to a discharge nozzle is characterized in that movement of the baffle is effected by the set point setting means and by movements of an indicator the position of which reflects the variable condition. The discharge nozzle 3, Fig. 1, is located in a conduit 2 which, downstream of the nozzle, leads directly to a bellows 12 and via a restrictor 16 to a bellows 13 and a controlling capacity 17. The bellows 12, 13 are spring-loaded and mounted on a common base 11. The baffle 4 is connected by a rod 6 to a floating lever 7 connected at one end to a pivoted lever 9 fixed at 10 to the base 11. The other end of the lever 7 is attached to a lever 22 connected to a nut 23 on a screw rod 24. The lever 22 is also connected by a rod 25 of adjustable length to a lever 26 pivoted at 27 and connected to a nut 28 on a screw rod 29 manually rotatable by a knob 38, the position of which is indicated by a set-point indicator 37 carried by a cable 35 which moves over pulleys 36 and round a drum 34 on the rod 29. A cable 31 carrying a control point indicator 33 moves over pulleys 32 and round a drum 30 on the rod 24. The pointer 33 is movable in accordance with changes in the variable condition, e.g. temperature, and the regulator, not shown, is connected to the system by the conduit 42. In operation, movement of the pointer 33 due to a change in temperature, results in a corresponding movement of the baffle 4 and a change of pressure in the conduit 2. The floating lever 7 assumes a new position and the change of pressure is reflected within the proportioning bellows 12, and after a time delay determined by the restrictor 16 and the capacity 17, within the integral bellows 13. The base 11 moves until the baffle 4 is positioned so that the regulator restores the temperature to the set-point. The proportional action may be adjusted by varying the position of the pivot 19 of the lever 9. Pressure gauges 39, 40 measure the pressures within the bellows 12, 13.
