Patent GB-2098944-A (GB)
Title: Moorings
IPC: B63B22/02
Filed: 1981-04-01
Abstract: A mooring comprises a mooring buoy 1 and a flexible mooring cable extending down from the buoy to an anchorage point 3. The upper run of the mooring cable is located within a length of flexible tubular hose 11, the upper end of the hose being secured to the tail 8 of the buoy with the hose- end axis substantially upright. The lower end of the hole 11 is secured to a buoyancy assembly 9 which is anchored to the anchor point 3 by the lower run 6 of the cable. The hose is chosen such that its natural torsion stiffness resists relative twisting between its ends, thereby avoiding kinks in the cable and the need for swivels in the cable. Localised flattening of the hose is avoided by arranging the inner diameter of the hose to be not much greater than the envelope diameter of the cable, and, particularly, in deeper water, by providing access for water to enter the hose, for example at one or both ends, so that local hydrostatic pressures over the inner and outer walls of the hose are equalised. The buoyancy assembly may be distributed along the length of the lower run 6. <IMAGE>

Title: Machine tool
IPC: F16M5/00
Filed: 1982-03-04
Abstract: A machine tool comprises a machine bed 3 and a machine column 5 which are made of steel plate and are of welded construction. Formed in the machine bed 3 by vertical and horizontal dividing walls 38-41, are compartments 30-34. Compartments 31, 32, 33 are provided with openings 35 or charging tubes 36 for filling them with loose particulate quartz sand. The machine column 5 has two walls 50, 51 to provide a double-walled construction so that an outer compartment 52, which can be filled with quartz sand, and a hollow inner space 53 are created. The welded construction offers the advantage that the correct wall-thickness can be selected for each zone of the machine, and a thinner outer wall can be considerably strengthened by additional ribs; thus costs can be reduced on account of the lower weight of material. The ballast distributed in the chambers enables the weight of the material to be distributed in the optimum manner; in addition, vibrations are damped down over a wide frequency band. <IMAGE>

Title: A survival cabin for use at an offshore vessel
Inventor: BENGTSSON BO
IPC: B63C9/06
Filed: 1983-06-21
Abstract: A survival cabin for an offshore vessel includes a buoyant capsule (10), which normally hangs in a davit (30) at least partly outside a side of the vessel. The davit comprises a basically Z- shaped arm structure (35) which is pivotably supported at a considerable distance below the deck (32) of the platform, and carries the capsule at a single point. The davit is operated by a brake (42), which permits the folding- out of the davit to a position, where the capsule reaches a maximum distance from the side of the vessel. The davit pivoting is controlled by a hydraulic piston or pump brake. An accumulator in the hydraulic circuit raises the arm after release of the capsule. The capsule has a false bottom with holes to allow water inflow thus dampening impact with the water after a free drop, and it has an auto-pilot governing an azimuth propeller, which will bring the capsule away from a damaged vessel in a preselected direction. <IMAGE>
