Title: Squat Seabed Mooring System
IPC: B63B22/02
Filed: 1979-01-18
Abstract: For mooring a vessel such as an oil tanker, the lower end of an articulated swivelling arm is built into a squat base unit so that the upper end is free to rotate and to move around and over the base unit. A tanker hauls in a hawser and lifts the head of the arm into its reception chamber. It is thus moored by the arm to the base unit. The head of the mooring arm is held rigidly in the reception chamber and moves with the tanker. The base unit can be an oil reservoir and the arm can be hollow and be used to transfer fluid between reservoir and tanker. When not in use the mooring arm lies flat on the base on the sea bed, (or within a depression in the sea bed), where it is in no danger of damage from deep keels. <IMAGE>

Title: Integrating Filaments into a Strand
IPC: B65H69/00
Filed: 1979-05-03
Abstract: A method and apparatus for integrating a newly formed continuous filament into a continuous strand by the operations of drawing a plurality of continuous filaments 3 from a bushing 1 into a filament fan 4 by gathering the filaments 3 into a continuous strand 6 at a deflection roller 5. Should one of the filaments 3 break, a new continuous filament 8 is formed which is deflected by a chute 9 toward the roller 5. A water stream 13 separates the filament 8 from its associated initially formed needle and drop section and concomitantly predraws the filament 8 to an initial diameter conducive to integration. The filament 8 is further predrawn and conducted by the stream 13 between guide bars 15 to the roller 5 where the strand 6 and the filament 8 are jointly deflected along a common path X defined at least by the roller 5 and another roller 7 such that the newly formed filament 8 is drawn to its final diameter and integrated with strand 6. <IMAGE>

Title: Lock with Door-opening Restrictor
IPC: E05B47/02
Filed: 1979-05-22
Abstract: A deadlock for a door and like apertures to secure the door against unauthorised entry while permitting easy and frequent authorised entry. The deadlock includes a deadbolt (DB) extendable to engage loosely in a bolt box or socket (BB). The bolt is biassed by spring (BS) to be retracted when the door is open. A magnet (PM) on the door frame acts as an armature (AR) when the door is near to the frame to overcome the bias and extend the bolt to engage the socket and secure the door. The magnet can also pull the door in to align the bolt with the bolt box and keep the door closely seated in the frame. An electromagnet (EM) wound on the armature can be energised to overcome the permanent magnet and allow the bias to retract the bolt or can repel the bolt releasing the door. The bias and magnets can act on the bolt via a swing link (LK) and operating quadrant (OQ). Remote control via switches, which may be key operated, is possible. <IMAGE>
