Title: Apparatus and methods for laying underwater pipelines
IPC: F16L1/16
Filed: 1970-09-23
Abstract: 1,256,439. Laying underwater pipe-lines. SANTA FE INTERNATIONAL CORP. 23 Sept., 1970 [24 Sept., 1969], No. 45367/70. Heading F2P. [Also in Division H2] A pipe-line, cable &c. is laid along a predetermined underwater path wherein a pipe-line pulling assembly is coupled to the end of the pipe-line and, following a guide, draws the pipeline along the path. The guide comprises a cable C attached to an offshore anchor. The pipe-line pulling assembly comprises a sled carrying two cable grippers 20, 30 connected by twin hydraulic rams 22, one gripper 20 being rigidly attached to the sled and the other gripper 30 being axially movable on the sled. A second sled 40, carrying a pipe pulling head 46 to which is attached the end 43 of the pipe-line, is coupled to gripper 30 by a linkage 48, 50. Each gripper 20, 30, Fig. 6, comprises two fixed jaws 62, 64 and an intermediate movable jaw 66 operated by an inflatable tube 68. The pipe-line pulling assembly operates as follows: (a) hydraulic fluid is fed to gripper 30 to inflate tube 68 and cause the cable C to be gripped and simultaneously fluid is fed to the hydraulic rams 22 to extend the pistons 26 to cause the forward sled and gripper 20 to move forward along the cable C, until a predetermined pressure in the fluid is reached. (b) Fluid is then fed to gripper 20, to grip the cable C, and to the hydraulic rams 22 to retract the pistons 26, whilst the fluid fed previously is bled off to a reservoir. This causes gripper 30 to release the cable C and thus gripper 30 and the pipe-line are drawn towards the forward sled until the pressure in the fluid reaches a predetermined value, whence stage (a) is repeated, then stage (b) &c. Air filled tanks are carried by the two sleds to provide slight negative buoyancy and thus minimize friction for sled movement. The pipe-line pulling head 46 is sealed with the pipeline end 43 to retain some buoyancy in the pipe; line for similar frictional reasons. Before the pipe-line is detached water is allowed to enter via a valve in head 46 to settle the pipe-line in position.

Abstract: 1,201,273. Calculating deivces. AKUSTISCHE u. KINO - GERATE G.m.b.H. 5 Oct., 1967 [29 Nov., 1966], No. 45553/67. Heading G4B. [Also in Division H4] A movable member provides correlation of the setting of the gain of an amplifier (e.g. of a tape recorder) with the distance of a sound source from a microphone. A simple lamina (Fig. 1) has a volume control scale on the left and distance scales in metres, feet and paces on the right. A slide 2 correlates the volume control scale with distance for loud, normal or soft talkers. Alternatively circular scales are provided on a disc and a slide in the form of a sector of a circle has a window which displays "distance" for a given setting of a volume control (Fig. 2, not shown). A microphone housing 1 (Fig. 5) of cylindrical form has a slide 2c with two windows 3 one of which correlates the volume control scale with distance in metres and the other of which correlates the volume control scale with distance in feet. If desired, a single distance scale, calibrated in metres, Fig. 4 (not shown), may be used instead. In other arrangements, volume control and distance scales (Fig. 9) are inscribed on a cylindrical microphone housing and a rotatable ring 2g has a window 3 and a pointer 20b. The ring 2g may be moved axially so that the window registers with one of three distance scales, calibrated in paces, feet and metres respectively. In a simpler embodiment Fig. 7 (not shown), there is only one distance scale and the rotatable ring (2e) is not movable axially. In a further arrangement the ring (2d), Fig. 6 (not shown), has reference marks which co-operate with a distance scale above it and with a volume control scale below it. Alternatively the ring (2f), Fig. 8 (not shown), has a distance scale and a volume control scale around it. These cooperate with two marks on the cylindrical microphone housing. One mark is adjacent the distance scale and the other mark is adjacent the volume control scale. Alternatively the volume control may be set by a slide 12 (Fig. 11) on the amplifier housing, the slider 12 being of pointer form to correlate the volume control scale with a distance scale. In another arrangement, Fig. 10 (not shown), the volume control is set by a knob, which may be marked with a distance scale alone or, if preferred, with both a distance scale and a conventional volume control scale. In a further embodiment (Fig. 13, not shown) a circular volume control calibrated with a distance scale forms part of the microphone. The window of the slide, or the marks, may indicate maximum and minimum distances for a given volume control setting. The distance scale and volume control scale may be adjusted relative to one another to cater for use with alternative equipment.

Abstract: 1,163,270. Antibiotic enduracidin. TAKEDA CHEMICAL INDUSTRIES Ltd. 13 Oct., 1966 [13 Oct., 1965; 26 Oct., 1965], No. 45843/66. Heading C2A. An antibacterial antibiotic Enduracidin is obtained by culturing an enduracidin-producing strain of Streptomyces fungicidicus, e.g. strain B-5477 (ATCC 21013) or its mutant (ATCC- 21014), in a medium containing assimilatable carbon sources, digestible nitrogen sources and other nutrients necessary for the growth of the micro-organism under aerobic conditions of surface or submerged culture. The antibiotic is present in mycelium and clarified broth and may be isolated from both, preferably separately. The washed mycelium is extracted preferably with aqueous acetone or aqueous methanol under neutral or acid conditions, the pH of the extract adjusted to 5 to 6, the organic solvent removed therefrom, the pH adjusted to 3.0 and the extract then further extracted with ethyl acetate. The aqueous layer is separated, adjusted to pH 8.0 and then extracted with nbutanol. The n-butanol extract is treated with aqueous acid of pH 2À0 and the aqueous acid re-extracted with n-butanol at pH 8.0. After concentration, the antibiotic is precipitated by the addition of ether. Purification is by adsorption on activated charcoal followed by treatment with a weakly basic ion-exchange resin to remove the acid. The hydrochloride is formed by treating a methanol solution of the antibiotic with hydrochloric acid. Enduracidin (free base) is a colourless polypeptide antibiotic which on hydrolysis with hydrochloric acid gives threonine, serine, glycine, alanine and aspartic acid; melting point 205-225 C., decomposing 225- 240 C.; sparingly soluble in water and anhydrous solvents, soluble in aqueous acetone, aqueous methanol, aqueous butanol, aqueous acids and aqueous alkalies; elementary analysis 0=53À2%, H=6.54%, N=14.45%, Cl= 3.36%; specific rotation [α]<SP>23</SP> D =+8510 (C=0À5 in dimethylformamide); R f  value acetic acid-n-butanol-water (1: 4: 5) 0À450À1: ultra-violet absorption spectrum (Fig. 1) maxima 230 mÁ E<SP>1</SP>% 1cm.  =22015, 263 mÁ E<SP>1</SP>% 1cm.  = 15010 (95% aqueous methanol); infra-red absorption spectrum as in Fig. 2 (free form), Fig. 5 (not shown, hydrochloride form).

Abstract: 973,060. Knitting-machines. KENDALL CO. Dec. 4, 1962 [Dec. 5, 1961], No. 45845/62. Headings D1C and D1K. A knitted garment comprises a circular knit seamless band including an elastic yarn 51 inlaid in a generally spiraloid course of jersey-knit stitches of the band and an additional course of jersey-knit stitches between and separating turns of the spiraloid course in a portion less than the circumference of said band. In a scratch 50 (Fig. 5) the knitted stitch main yarns are shown at 52 (a, b, c and d) forming the spiraloid courses. Additional yarns 53 . . . 56 are knitted into a stitch of the main yarns as at 57 and then float across as at 58 to be knitted into a second stitch with the main yarns before being formed into an additional course for that portion of the circumference, whereafter it is floated across the normal fabric and later trimmed. The end of the additional course is secured in a similar manner as at the commencement. A second method of introducing the yarns Fig. 6 includes separately knitting the additional yarns as at 68 between the stitched 67. The structure shown in Fig. 7 is obtained by causing the alternate needles to take and to knit the main and additional yarns in that order at one feed and the intermediate needles to take and knit the additional and main yarns in that order at the other feed prior to the commencement of and at the end of each additional course. A further alternative construction Fig. 8 (not shown) is similar to that of Fig. 6 but the stitches composed of both yarns are staggered. Bare spondex may be used for the inlay yarn and the garment after knitting are stretched over a form and heat set to final shape. Fig. 9 illustrates the layout for a modified cam ring 90 for the Scott & Williams AM F circular knitting machine modified by making the left clearing cam 98 adjustable by inserting a dividing cam 107 and by modifying the intermediate jack clearing cam 104 which was formally triangular to make it adjustable by the addition of a movable auxilliary cam 105. Intermediate jacks are raised by cam 104 with cam 105 down and then raise the alternate needles to the tuck position where they take elastic yarn. Intermediate needles are not raised by the intermediate jacks and hence the elastic yarn passes over their hooks. These intermediate needles are lowered to the level of the similar ribs by the dividing cam 107. The path of the needle butts is indicated at 108, the path of the alternate needle butts at 109 and the path of the intermediate needle butts at 110. Thermoplastic or non thermoplastic elastic yarn including natural and synthetic rubber and elastomeric forms of other polymers may be used.
