Filed: 1999-09-20
Abstract: A simple traction attachment which is easy to assemble and connect to a bicycle is provided. This attachment enables the rider to traverse along a snow covered terrain by implementing a wider traction belt at the back wheel. This belt serves the dual purpose of preventing the bicycle wheel from digging deep into the snow and imparting motion through the rear wheel of the bicycle. The front wheel is connected to a simple ski-like attachment as there is no torque input that needs to be transmitted at this wheel, for the mobility of the bicycle. To ensure that there is no slippage in the transmission of torque at the rear wheel, the bicycle attachment, which will be referred to as the b-track, is designed such that a chain drive is utilized. This chain is connected to two sprockets located at the center of the rear wheel and at the front side of the b-track on the rear wheel. The uniqueness and novelty of this invention is the ease with which one can assemble this product and the relatively low cost of manufacture.

Abstract: A smart card payment system (51, 52, 53) using stored value in the form of serialized (51-L) electronic coins (51-D) and electronic bills (51-0, 52-0, 53-0), which provides efficient security monitoring without the need for full centralized accounting of each transaction. Central monitoring of the system-level security includes statistical sampling techniques coupled with efficient tracing of the transaction path of an electronic coin (51-D) back to its source. Only small amounts of data storage and transmission (51-E, 52-2, 52-11) are utilized, eliminating the need for large centralized databases of transaction records. Consumer privacy as well as flexibility in making card-to-card monetary transfers are thereby enhanced, while allowing verification of system-wide security as well as rapid detection and tracing of security breaches. Multiple editions of electronic coins (51-D) permit transparent and periodic renewal of the system and re-establishment of a security baseline, and also provide for the regular reclamation of stored value lost or abandoned by consumers.

Title: Production of low sulfur syngas from natural gas with c4+/c5+ hydrocarbon recovery
Inventor: ALEXION DENNIS GEORGE
IPC: B01D53/04
Filed: 1999-01-15
Abstract: Sour natural gas is processed to remove the sulfur compounds and recover C4+/C5+ hydrocarbons by scrubbing the gas with an amine solution to remove most of the sulfur, followed cooling the gas to remove C4+/C5+ hydrocarbons and more sulfur compounds as liquid condensate to produce a gas having less than 20 vppm of total sulfur. The condensate is sent to a fractionator to recover the C4+/C5+  hydrocarbons. The sulfur and hydrocarbon reduced gas is contacted first with zinc oxide and then nickel, to produce a gas having less than vppb of total sulfur which is passed into a synthesis gas generating unit to form a very low sulfur synthesis gas comprising a mixture of H2 and CO. This synthesis gas is useful for hydrocarbon synthesis with increased life of the hydrocarbon synthesis catalyst and greater hydrocarbon production from the hydrocarbon synthesis reactor. Contacting the synthesis gas with zinc oxide further reduces the sulfur content to below 3 vppb.
