Abstract: 1,248,676. Pipe laying vessels. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 13 Oct., 1969 [14 Oct., 1968], No. 50079/69. Heading B7A. [Also in Division F2] A vessel for laying a pipeline on the floor of a body of water comprises a plurality of hollow elongated spaced-apart hull members or pontoons, a plurality of vertically extending columns carried by the hull members, a deck supported by the columns for carrying pipeline laying equipment, including a pipeline ramp and adjusting means for vertically adjusting the height of the ramp with respect to the water surface, and pumping means for selectively flooding and evacuating the pontoons so as to vary the buoyancy of the vessel. Pipeline laying vessel 10 described in the preferred embodiment comprises a pair of spaced hull members or pontoons 12 (Fig. 2) interconnected by structural members 13. Pontoons 12 are elongated hollow and buoyant thus forming water-tight compartments. The pontoons 12 are raked fore and aft and their longitudinal cross-section is rectangular. Each pontoon carries a row of evenly spaced elliptical columns 19, placed close to the outer edges of the pontoons in order to increase the transverse stability of the vessel. The columns may alternatively be circular in cross-section (Fig. 2A, not shown). The columns 19 support deck structure 16 comprising an upper working deck 17 and a lower deck 18. The upper working deck 17 includes an elongated narrow extensible portion 24 for extending the length of the pipeline assembly area. Equipment for joining pipe sections 25, such as cranes 26, welding stations 41-46, coating station 47, tension machine 48 and hatches 27 [for access to pipe storage bins (28, Fig. 4, not shown)] are also provided. The pipeline is transferred to the water by an articulated ramp or stinger 20, Fig. 1, which is adjusted so that its lower end 21 is always near the water surface. In heavy seas the vessel is submerged to depth D by partial flooding of pontoons 12, and the ramp is in a position shown in Fig. 1. In shallow waters the pontoons are pumped dry and ramp 20 is lowered to the water surface 22. Ramp 20 is preferably located centrally of vessel 10 along the longitudinal axis L-L, Fig. 2, so as to reduce the heave motion of the pump line due to the rolling motion of the vessel.

Abstract: 1,253,388. Rotary positive-displacement engines. ROLLS-ROYCE Ltd. Oct. 15, 1969 [Oct. 29, 1968], No. 51284/68. Heading F1F. An I. C. engine has a crank-shaft 19 fixed to a stationary structure 13 and carrying a vaned rotor 22 to which an annular housing 20 is coupled so as to rotate therewith at substantially the same speed. Fuel-air mixture fed through a conduit 12 is pre-compressed by a centrifugal compressor  14 before it enters spaces between the rotor vanes 23 by way of a conduit 16 and a port 57 in a rotary valve-disc 60 between ported flanges 31, 43 on the rotor. Slots 28 permit hot gases to ignite the compressed mixture in the spaces on the trailing sides of the vanes as the latter pass through the top-dead-centre position, there being slight movement of the vanes back and forth across these slots as the rotor and housing rotate. Slots 26 ensure turbulence of the mixture. Exhaust gases escape through a duct 36 controlled by a rotary valve-disc 61 adjacent a flange 32 on the rotor. Mechanism coupling the housing to the rotor includes a gear system 38 wherein teeth 42 on the flange 43 mesh with gears 41 on an eccentric wheel 46 carried by the crank-shaft and a gear 37 is fixed to the impeller so that the latter contra-rotates relative to the rotor and housing.

A fibrous material for example a non- woven fabric, or a yarn as described in specispecifications 1,114,151 and 1,131,282 respectively, or discrete fibres - is produced by drawing an extruded foamed thermoplastic material to orientate it essentially in one direction, and breaking the walls of, the foam down by the action of a turbulent stream of fluid to form the fibrous material. The composition, production, and drawing of the foamed material is as described in the above mentioned specifications. The fluid may be air, nitrogen, argon, or helium and may contain carborundum particles, or a liquid, which may be a non-solvent for, or cause a partial swelling of, the foamed material, may be used, for example water, acetone, methyl alcohol, ethyl alcohol, benzene, toluene or xylene. The fibrous material may pass through a tube having solid or porous walls - for example of wire gauze. There may be several jets of fluid arranged around the tube or there may be an annular jet. The fluid may be directed in a direction inclined to or opposed to the direction of movement of the material. The fluid treatment may be preceded by a rubbing, rolling, twisting, shaking, or beating treatment, for example by being passed through a nip between a series of reciprocating rollers or between reciprocating bars.

Abstract: 1522312 Trimming residual flesh from fish skeletons BLUE LAKE FORGE CO Ltd 28 Nov 1975 [28 Nov 1974] 51619/74 Heading A4C [Also in Divisions A1-3] Apparatus for trimming residual flesh and associated lateral bones from fish skeletons after removal of fillets comprises means for the successive feeding of the skeletons to a cutting station at which a pair of cutting devices 17A, 17B are located, the cutting devices being spaced apart laterally with respect to the skeleton feeding direction and being adapted to sever simultaneously from the skeletons two side portions while allowing unobstructed passage of the backbones, means for detecting the approach to the cutting devices of an enlarged portion of the skeleton, such as a belly portion, and operative on detection of the enlarged portion to actuate means for varying the spacing of the cutting devices so as to allow substantially unobstructed passage between the cutting devices of the enlarged portion, separating substantially all of that portion from the severed side portions. The means for feeding the skeletons include a belt 13 and feed wheels 15, 16 adapted to engage successive skeletons. The cutting devices each comprise an upper serrated cutting knife 18 and a pair of lower serrated cutting knives 19 rotatable about a common axis parallel to the axis of rotation of the upper knife, the lower knives being spaced apart axially to embrace a peripheral portion of the upper knife so as to effect a shearing action. The teeth on wheels 15 and 16, on upper knives 18 and on the innermost lower wheels of each pair 19 are trailing with respect to the skeleton movement, and the outermost wheels of each pair 19 are leading with respect to the skeleton movement, so that the back bone is not held by the teeth and passes to a waste shoot 24, whereas the side portions are carried by the outermost knives and fall on to a delivery conveyer 22. A pivoted feeler arm 27 projects into the path of movement of the belly cavity portions and is moved upon encountering a bell cavity portion, thus triggering a fluid-pressure actuator which alters the spacing between the cutting devices 17A, 17B, when the belly cavity portion of the skeleton has reached the cutting station.
