Title: Spill overflow prevention system for tanker vessels
IPC: B63B43/00
Filed: 1981-05-05
Abstract: A tanker vessel has a spill overflow prevention system consisting of a longitudinally positioned trunk line, with branch lines coupled at one end to the trunk line and at the other end to the cargo compartments of the vessel. Valves are coupled to the branch lines intermediate their ends for allowing free flow of fluid chemical and petroleum products from the cargo compartments to the trunk line through the branch lines. A retention tank is positioned in the vessel and coupled to the trunk line for receiving fluid chemicals and petroleum products from the trunk line. Fluid chemical and petroleum products overflowing from the cargo compartments of the vessel are directed from the compartments through the branch lines and trunk line to the retention tank thus preventing overflow of the products externally of the compartments. The branch and trunk lines are dimensioned so as to prevent any overpressurisation of the compartments during an overflow. The overflow system reduces safety hazards, cargo loss and the pollution of coastal waterways and ports caused by tank overflows during loading operations, transfers, discharge or cargo expansion in a tank vessel by directing any overflows from the cargo compartments into a retention tank.

Patent PT-98096-A (PT)
Inventor: TROKHAN PAUL DENNIS
IPC: B29K101/00
Filed: 1991-06-26
Abstract: A backside textured papermaking belt is disclosed which is comprised of a framework and a reinforcing structure. The framework has a first surface which defines the paper-contacting side of the belt, a second surface opposite the first surface, and conduits which extend between first and second surfaces of the belt. The first surface of the framework has a paper side network formed therein which defines the conduits. The second surface of the framework has a backside network with passageways that provide surface texture irregularities in the backside network. The papermaking belt is made by applying a coating of photosensitive resinous material to the reinforcing structure and pressing the reinforcing structure into a deformable surface, so that the deformable surface forms protrusions which exclude resin from certain areas which when cured will lie along the backside of the belt, and then exposing the photosensitive resinous material to light of an activating wavelength through a mask which has transparent and opaque regions. A process for making paper products is also disclosed which involves applying a fluid pressure differential from a vacuum source through the belt to a partially-formed embryonic web of papermaking fibers. The fibers in the embryonic web are deflected into the conduits of the papermaking belt by the vacuum pressure while the papermaking belt and the embryonic web travel over the vacuum source. Following the deflection, the paper web is impressed with the paper side network of the belt, and dried to form the final product.
