Abstract: The invention refers to a tying system employing an accessory bearing a quick attachment hook, for tying a plastic cover film for agricultural crops such as soft fruit covers. Cultivation of soft fruits in covered space has been growing in recent decades. Several solutions have been developed including greenhouses or gable systems. The placement, fastening and fixing of the plastic film is achieved with ropes, elastic cords or soft PVC tubing. However, the cost of binding the plastic film is significant as skilled staff and considerable amounts of man hours are required to tie the plastic film to the supporting structure. Tying the film, in most cases, is carried out by employing knots on grommets that the plastic films.

Abstract: A tie down system includes at least one device hook having a hook base; at least one hook opening in the hook base; a generally elongated hook shaft extending from the hook base; a curved hook finger extending from the hook shaft; a hook base extension extending from the hook base in spaced-apart relationship to the hook shaft; and a hook slot between the hook shaft and the hook base extension.

Abstract: There is disclosed a system and method for retaining portable rechargeable devices to recharging stations wherein one or other or both of the recharging station and the portable device are provided with connecting means adapted for temporary releasable connection of the two. This is particularly advantageous when used with recharging stations, which permit the device to be recharged in multiple places on the recharging station, providing a positive means of retaining the device. This is particularly advantageous if the recharging station is to be used in a mobile environment such as a car, or on a wall or ceiling.

Abstract: A sail fastening apparatus (18) for a yacht. The apparatus (18) comprises a first track (21) extending along a sail clew (12) in a direction generally normal to a preferred vertical sheeting angle of the sail, a first carriage (22) slidably mounted for movement along the first track (21), and a sheet (16) extending between the first carriage and a sheeting point (27) on the yacht aft of the clew. The first carriage tends automatically to adopt a stable equilibrium position on the track such that the preferred vertical sheeting angle (B) for the sail is maintained.

Abstract: A sailboard boom clew fitting member comprising a pair of members (11 and 12) engagable with the ends of a pair of boom members of the boom. One member (11) having a transversely directed socket. The pawl (13) being snugly engagable in the socket and being retained in engagement by a latch member (22) pivotally supported by one of the members and resiliently biassed into a position at which it will be engaged with the engaged pawl member and socket to prevent their disengagement. The pawl member and socket when engaged providing a support surface (15, 17 and 19) for a rope which fixes the clew of a sail to the clew fitting.

Abstract: The cringle or grommet disclosed is adapted for applying substantial loads to a fabric sail such, for instance, as a main sail or a genoa jib, and may be located at the clew of the sail to which point some rope or the like is attached for trimming the sail. The cringle employs a pair of complementary ring members, one on one side and the other on the other side of the fabric of the sail, each having a multiplicity of holes therethrough which are in registering relation and through which holes there is located rivets to clamp the rings together on the sail. The rings may be applied to the sail before an opening through the rings or through the sail is made after which an opening is made through the rings by a heated tool guided by the inner edge of the rings, which step melts the synthetic fabric of the sail so that the melted thickened periphery enters the chamfered inner edge of the rings, thus assisting in applying more resistance to a sail being pulled from between the rings.

Abstract: A grumment for sail cloth in which two rings are positioned around the edge of a hole therein which edge has been ravelled and has a thermosetting adhesive smeared thereon and tightly clamped against the edge by a torus-shaped collar enclosing the rings.
