Title: Multi-body offshore arrangement
Inventor: BRADLEY MICHAEL SHAUN
IPC: B63B21/50
Filed: 1981-09-22
Abstract: This specification describes a compliant multi-body offshore concept suitable for production and/or drilling purposes wherein the buoyant mooring 1 and load carrying elements 4 are separated. The buoyant mooring elements 1 are attached to the sea floor by means of tensioned vertical moorings 3. Because of the separation of the load carrying and tension leg mooring elements the invention is less susceptible to the effect of increasing payload reducing mooring tension which occurs in the conventional tension leg platform. The central process facility may be easily moved to other locations, and the comparatively small size of the tension leg mooring buoys eases their fabrication and installation. The invention may also be used for the deep water or hostile environment mooring of conventional semi- submersibles where the spread of a catenary mooring would prove to be excessive. <IMAGE>

Title: Wind-operated automatic control device for a yacht
IPC: B63H25/04
Filed: 1982-01-06
Abstract: A wind indicator 1 is connected to the steering arm of a rotating shaft 13 by means of a gear-like connection 5, 9, the load arm of the rotating shaft 13 being connected to the adjustable blades 35 of a blade-wheel by means of a coupling 18, 19, 27, 29, 32. The blade wheel is coupled to an auxiliary rudder or the main rudder 47 of the yacht by a driving shaft 40 and a driven shaft 43 which are connected together by a mitre gear 41, 42, the rudder 47 being coupled to the shaft 43 by a cable 46. The driven shaft 43 is provided with a spindle nut 45 which serves to adjust the pivot 15 of the rotating shaft 13, and is thereby integrated in the gear-like connection of the wind indicator 1 to the blades 35. If the yacht goes off course, the wind indicator 1 swings out of its neutral position and this causes the blade angle of the blades 35 to be adjusted which in turn leads to a corresponding deflection of the rudder 47. This provides a particularly efficient course correction with negligible loss of travelling speed. Adjustment of the pivot 15 of the rotating shaft by the spindle nut 45 tends to move the indicator 1 and the blades 35 back to their neutral positions after course correction. <IMAGE>

Patent GB-2111537-A (GB)
Title: Automatic washing machine
Inventor: CAMPAGNOLO FLAVIO
IPC: A47L15/42
Filed: 1982-11-23
Abstract: An automatic washing machine is provided with a decalcifier 11 which, during one phase of the operating cycle of the machine is regenerated by being flushed through with water which has passed through a salt container 12. The water for this regeneration phase comes from a tank 8 which has an internal basin arrangement 17 which in other phases of the machines' operation returns water from the free air-gap arrangement 6 at the inlet end of the water feed circuit to the tub 4. The decalcifier 11 discharges into the tub 4 via a one-way-valve 10 and the discharge side of a pump 20 of the machine. In order to initiate the regeneration of the decalcifier 11, the pump 20 is operated at the same time as the water inlet valve 5 is opened. The operation of the pump 20 causes the one-way valve 10 to close and this in turn causes the interior of the tank 8 below the basin 17 to fill with a predetermined amount of water. The pump 20 is then stopped enabling the valve 10 to open and thus the water which has accumulated in the tank 8 to discharge via the salt container 12 and a one way valve 13 through the decalcifier 11. <IMAGE>
