Patent GB-2138531-A (GB)
Title: Spooling Previously Laid Pipeline
Inventor: TESSON A
IPC: F16L1/20
Filed: 1983-10-06
Abstract: A method of spooling a portion of a previously laid pipeline on to a reel pipelaying vessel comprises the steps of (a) maintaining the vessel in a station keeping mode and the pipeline under sufficient tension to hold same in a desired profile while the vessel is in said mode; (b) locking the reel against rotation in the unspooling direction when the vessel is in said mode with the one end of the pipeline secured to the reel; and (c) spooling at least a portion of the pipeline onto the reel while maintaining the pipeline under sufficient tension to hold the desired pipeline profile. The pipeline is maintained under such sufficient tension by (1) placing the reel drive mechanism into a spooling mode; (2) adjusting pipe straightening means for a no-load condition whereby the straightening means imparts substantially no straightening force to the pipe passing therethrough in the spooling direction; (3) gradually increasing drive torque imparted to the reel by the reel drive mechanism to overcome forward thrust imparted to the vessel and begin rotating the reel in the spool-up direction; (4) thereafter disengaging the means locking the reel against rotation in the unspooling direction; (5) thereafter spooling at least a portion of the laid pipeline; (6) thereafter gradually reducing the reel drive torque to a value which substantially balances the forward thrust imparted to the vessel to thereby decrease the rate of spooling rotation of the reel towards zero when the desired amount of pipeline has been spooled onto the reel; and (7) thereafter again locking the reel against further rotation.

Patent GB-874471-A (GB)
Abstract: 874,471. Selective punching-machines. BUD, M. Dec. 13, 1957 [Dec. 19, 1956], No. 38650/56. Class 31 (2). [Also in Group XIX] Apparatus for recording time periods on a card having e.g. 600 elemental areas arranged in 10 rows and 60 columns comprises two punches 24, 25, Fig. 1, arranged to punch in the same elemental area, one 24 being operated at the beginning of a period by a hand lever 26 and the other 25 at the end of the period by lever 36. The punches work in a block 23 slidable on a rod 5 in a carriage 2 itself slidable on rods 11, 12. Clockwork 21 drives the block 23 from row to row at intervals of six minutes through ratchet bar 55 and pin 57 and the block 23 is located in each row by ratchet notches 53 in a bar 6 and spring-loaded pawl 54. At the end of each hour a spring 62 returns the block 23 to the first row and the clockwork 21 drives the carriage 2 into position over the next column through pawls 22 and ratchet racks 15. In and out records may be distinguished solely by their different positions within an elemental area or the difference may be emphasized by making the punches 24, 25 of different shapes, suitable pairs being shown in Fig. 3. In another embodiment in which a punch carrier 123, Fig. 6, is driven through clockcontrolled electromagnets, depressing a start button energizes a solenoid 127 causing the punch 124 to operate. Depressing a finish button 136, Fig. 13, starts a motor 1176 which drives three cam discs of which disc 1181 closes a holding circuit while disc 1177 simultaneously closes the circuit of a solenoid 1167 which shifts the punch carrier to bring a punch 125 into the position relative to the card carrier just vacated by the punch 124. Then the disc 1178 closes the circuit of solenoid 137 momentarily to operate punch 125 after which the disc 1177 breaks the circuit to the solenoid 1167 to release the carrier to spring back to its former punching position and the disc 1181 opens the holding circuit. Thus distinguishing holes are punched for the start and finish of a period. In another embodiment, Fig. 14, an eccentric, suitably shaped punch 271 is caused to turn through half a revolution when operated at the end of a period in order to make a distinction between start and finish holes.
