Title: Method for Laying Underwater Pipeline

IPC: F16L1/26
Filed: 1967-09-26
Abstract: 1,154,199. Laying under-water pipe lines; pipe couplings. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 26 Sept., 1967 [28 Sept., 1966], No. 43731/67. Headings F2G and F2P. A method of laying an under-water pipeline recoverable to the surface of a body of water, comprises connecting the pipeline to a pair of separate fixed facilities, at least one of the fixed facilities being on the water floor, suet that the connected pipeline will have an intermediate looped portion ro tatable upwards from the water floor to the water surface, and vice versa about an axis substantially containing the fixed facilities. As shown a pipe line 18, connected to a wellhead 16, is first laid along the water bed 13 in the direction of a central collecting facility 17 over a guide 14 on a barge 10 which gradually changes course by substan tially 90 degrees so that the pipeline is laid in an arc and held in this configuration e.g. by anchors 24 as shown, by guide lines from an auxiliary vessel or, by the weight of the pipeline when the end of the pipeline has reached a position where the distance X is at least equal to the depth of water the pipeline is lowered by a recovery line 20 and marked by a buoy 19. The pipeline 21 is connected to the facility 17 and then laid in an arc of substantially 90 degrees in the same direction as the pipeline 18. The lines 18, 21 could be laid simultaneously by using two vessels. The free end of the pipeline 18 is raised and is joined to the free end of the pipeline 21 by means of a connector (22), Fig. 5, not shown, a method of installing the connector 22 being described with reference to Figs. 19-23, not shown. The looped line 18, 21 is then lowered by moving the barge in the direction of an arrow, Figs. 6, 7, not shown, away from the loop and by paying out a guide line under controlled tension, the loop swinging in an arc about an axis containing the fixed facilities 16, 17 until it reaches the water bed. In an alternative method the pipelines 18, 21 first laid in arcs are laid to extend, e.g. for several hundred yards parallel to each other, the free ends of the pipelines being then secured by a connector having a return bend with an arc of 180 degrees. In this manner the necessity for a second guide on the barge, Fig. 4, not shown, is avoided. In another method the pipelines 18, 21 are not laid in a curve, but in a straight line with overlapping ends which are then raised to form a vertical loop and which, after fitment to a connector, are lowered in the manner described above. Alternatively the pipelines can be drawn together in a straight line to reduce their sag and to form a vertical loop for fitment to a connector member, buoys being connected to the pipelines to prevent them from being restored to the original catenary conditions. Other methods of joining vertically looped pipelines are also described.

Title: Correction of block errors in transmission of data
IPC: H04L1/00
Filed: 1969-09-10
Abstract: 1,274,706. Error correcting system. R.C.A. CORPORATION. 10 Sept., 1969 [12 Sept., 1968], No. 44608/69. Heading G4A. The invention relates to an error detecting and correcting system. An n bit word is arranged into k blocks each having a check bit and a word composed of the blocks is transmitted serially or in parallel. To form the blocks the n bit word is arranged into k subsets S 1 -S k , where k must be a prime number. The subsets form the rows of a matrix whose ith column is X (i-1)t+1 , X (i-1)t+2 ,...X it 0,0,0, X it  ... X (i-1)t+1  cyclically shifted i-1 positions, where t=(k-3)/2 e.g. for n=14, k=7, t=2. A parity bit aj is formed for the jth subset of the matrix e.g. a 1  = X 1 #X 3 #X 6 #X 14  where # = exclusive OR and is inserted in the position occupied by the centre 0 in each row as shown in brackets in the matrix. Digits to form k blocks B1-k to be transmitted are obtained from the columns of the matrix such that B 1 =X 1 X 2 A 4 , B 2 =X 3 X 4 A 5 , B 7  = X 13 X 14 A 3  so that each block contains three digits from three different subsets. The blocks are transmitted and when received are used to form a syndrome Z = Z 1 Z 2 Z 3 ...Z 7  formed by the modulo 2 summation of the digits in each subset formed from the received words. If the words are correct each Z i =0 and Z i =1 only if an odd number of received S i  is in error. If an information bit in a single block is wrong the syndrome Z will include a pair of "1"s. If a check bit in the block is wrong Z will have a single 1 and the position of the "1" or "1"s will indicate the faulty bit e.g. if B 1  is incorrect Z=e 1 <SP>1</SP> e 2 <SP>1</SP> 0 e 3 <SP>1</SP> 0 e 2 <SP>1</SP> e 1 <SP>1</SP> where e is "1" if the corresponding received x or a is wrong. Since the pattern is symmetrical and a similar pattern cyclically shifted will apply to the other blocks B 2 -B 7  an analyser can be used to check the pattern, e.g. Z 1  = (Z 1 #Z 7 ) + (Z 2 #Z 6 ) +Z 3 +Z 5 =0 thus if d 1 =Z 1 , d 1  = 1 only if the symmetry pattern is as above or all zeros. A similar pattern cyclically shifted holds for the other values. If the error is correctable then exactly one of the d's is a "1". If more than one "1" is present there is an error in one or more analysers. If all the d's are zero then the error is not correctable. In binary operation the bit identified by the syndrome pattern is complemented to correct the error. If k = 19, B=8 which is a common size of a byte in computers.

Abstract: 1526085 Controlling variable displacement pumps PLESSEY CO Ltd 26 Oct 1976 [4 Nov 1975] 45724/75 Heading G3P A variable displacement pump 2 for supplying fluid through a valve 82 to a hydraulic system which is normally supplied by a main pump has two piston and cylinder actuators 31, 33 for urging a swash-plate 30 towards maximum and minimum pump displacement positions respectively, and means 70 responsive to a condition in the system (i.e. downstream of the valve 82) for controlling the supply of liquid from the system to operate means 50 through which liquid is supplied to the actuator 33, the means 50 being operative, when it is receiving liquid, to move the swash-plate to an on-swash condition to supply liquid to the system in the event of a lack of output from the main pump. When the pump is started, non-return valve 82 is closed and no liquid is pumped to the valve 70, and the spool of valve 50 is urged to the right (as shown in Fig. 1) by spring 100; thus liquid supplied to the actuator 31 moves the swash-plate 30 to the maximum displacement position, and none reaches the actuator 33 until the pressure acting on the valve spool balances the spring. As the pressure rises the valve 82 is opened and fluid is supplied through the valve 70 to act on the spool of valve 50 in opposition to the pump pressure, so that this valve (and hence the pump displacement) is controlled in dependence on the pressure drop across orifice 80. When the pressure in the system reaches a predetermined level the valve 70 interrupts the supply of control liquid to the valve 50, which cuts off the supply to the actuator 33, so that the swash-plate is moved to the minimum displacement position, and the pump remains in this stand-by condition until the pressure in the system falls to allow the valve 70 to open. The valves 50, 70 are described in detail with respect to Figs. 2-4 (not shown).
