Abstract: A process for the manufacture of a homogeneous fibriform element comprising a smoke-modifying agent. In the process a mixture comprising a solution of a polysaccharide (an alginate for example) and a smoke-modifying agent (menthol for example) is fed through nozzle means, and a jet of said mixture issuing from the nozzle means is brought into contact with a solution containing multivalent cations (such as calcium ions). Solidification of the mixture is thus effected. In a second aspect of the invention, a fibriform element is manufactured by passing a thread through a mixture comprising a solution of a polysaccharide and a smoke-modifying agent whereby the thread is coated with the mixture. The coated thread is brought into contact with a solution containing multivalent cations thus to effect solidification of the mixture on the thread. A fibriform element as manufactured by the inventive process and a smoking article comprising such a fibriform element are also claimed.

Title: Fish farming system and method
Inventor: ZEMACH SHALOM
IPC: A01K61/00
Filed: 2001-07-27
Granted: 2006-08-08
Abstract: The invention provides a deep-water fish farming system comprising a fi sh cage of controllable buoyancy having one or more chambers, which can be submerged and refloated at a controllable rate to any depth. A winch mechanism mounted preferably on a platform that covers a section of the cage releases and gathers a cable connected to a sinker. When the combined weight of the system overcomes the buoyancy, the fish cage is submerged to a depth determined by the effective length of the cable between the winch mechanism and the sinker, with the sinker touchi ng the sea bottom. The submerged cage is refloated to the surface by remotely activating the winch mechanism, thus releasing the cable, while keeping the sinker on the s ea bottom. When the cage is refloated to the surface, the buoyancy is increased to allow pulling of the sinker from the bottom. The invention further provides a meth od for submerging and raising a fish cage at a controlled rate to any desired depth in deep water.

Title: Signal blocking for a base radio control station
Inventor: OZLUTURK FATIH
IPC: H04B17/00
Filed: 1996-06-27
Granted: 2005-09-27
Abstract: A method and apparatus for communication data signal blocking for a base radio control station (RCS) which wirelessly communicates with subscriber units (SUs) via a spread spectrum communication system is disclosed. A transmitter sends signals as a baseband combined signal over global and assigned channels to SUs. The SUs are set to initial power levels and the power levels are adjusted in advance of receiving signals on assigned channels. The power levels are combined to define an RCS transmitter power level, which is preferably a root mean square value of the baseband combined signal. The transmission power levels are adjusted in response to corresponding power control signals received from the SUs. Transmission of a new communication data signal on an assigned channel is blocked if a predetermined RCS transmitter power level limit is reached before commencing transmission of that signal.

Granted: 2012-06-26
Abstract: A system is provided for unloading accumulated liquids and enhancing the recovery of gas from a reservoir having diminished pressure. An annulus between a tubing string and casing is isolated by a packer and continually pressurized with a slipstream of compressed gas while the well continues to produce. A unique valve positioned in the tubing string is shuttled between a production position in which production fluids are permitted to bypass the valve to the surface and a lift position in which the bypass is blocked and an unloading port is opened to vent high pressure annulus gas to the tubing string above the valve, lifting accumulated liquids with it. Preferably, the valve is actuated to the lift position by the impact of a plunger dropped from a lubricator at the wellhead, when the pressure in the annulus has reached a predetermined threshold. When the gas has been vented and the pressure in the annulus drops, the valve is actuated to the uphole production position as a result of the higher reservoir pressure.
