Patent GB-2405176-A (GB)
Title: Load floor latch including pawl retaining mechanism
Inventor: BERG GERT
IPC: E05B65/12
Filed: 2004-08-18
Abstract: The present invention relates to a load floor latch for securing a first closure member to a second closure member panel. When the first and second closure members are fastened, the latch is opened by actuating the handle 2 and the pawl 4 is retracted into the latch. A biasing device such as a torsion spring acts on a retaining locking arm 9 so as to pivot the locking arm such that it engages a slot on the pawl 4. This maintains the pawl in the retracted position. When the first closure member to which the latch is attached is closed so as to bring the first closure member into a closed position with respect to the second closure member, a projection 8 on the locking arm contacts a contact member such that the locking arm is pivoted and the locking arm no longer remains in the slot in the pawl. The pawl is then free to extend out of the latch to a latched position by the action of a compression spring and engage a keeper on the second closure member to thus fasten the first and second closure members. The pivoting locking arm may be replaced by a displaceable detent in a further embodiment which operates in the same way as the first embodiment.

Title: Fire fighting in liquid storage tanks
Inventor: SCOTT STEPHEN
IPC: A62C31/05
Filed: 2006-05-24
Abstract: A fire extinguishing installation for location within a liquid storage tank (10) is disclosed. The installation comprises a delivery nozzle (20) for delivering fire extinguishant, a support structure (22) for the nozzle (20), and means such as a foam generator (40) for delivering extinguishant to the nozzle (20). The support structure (22) is configured to support the nozzle (20) such that it can rotate about a generally vertical axis when in use. When the foam generator (40) is energised, the nozzle will rotate and will evenly distribute extinguishant within the tank (10). The extinguishant will subsequently rise to the surface of the liquid stored in the tank (or fall onto it if the level is low) thus creating an even surface layer to extinguish the fire effectively. A secondary effect is that the cold foam mixture rising from the bottom of the tank will create a movement of cooler fluids from the lower regions of the tank thus cooling the liquid surface and further reducing vapour emissions. The delivery nozzle (20) may comprise a single nozzle or plurality of nozzles or may be in the form of a rotating tube having a plurality of openings (48) being upwardly directed wherein the size of the openings increases with distance from the support pipe.
