1.WO/1986/000065PROCESS FOR TREATING FLUE GAS WITH ALKALI INJECTION AND ELECTRON BEAM

WO - 03.01.1986

Clasificación Internacional B01D 53/50 Nº de solicitud PCT/US1984/002069 Solicitante RESEARCH COTTRELL, INC. Inventor/a GLEASON, Robert, J.

A process uses limestone injection into a combustion boiler burning pulverized coal or liquid hydrocarbon fuel. Effluent gas from the boiler is humidified and cooled to below 200^oF. During the humidifying and cooling step, sulfur dioxide removal occurs in addition to that which takes place in the combustion zone of the boiler. The effluent gas and unreacted alkali is then fed into an electron beam irradiation chamber which produces energetic conditions for rapid reaction of sulfur dioxide and nitrogen oxides in the presence of water vapor. The remaining unreacted alkali reacts rapidly and in-situ with the sulfuric acid and nitric acid formed in the electron beam chamber.

An operator powered vehicle (200) configured to be ridden by an operator in an upright or forced weight position wherein muscle force provided to pedals (40A, 40B) is augmented by the weight of the operator (30) and by an upward force provided by the operator's arms on the handle bars (31A, 31B). Lever-type pedal arms (38A, 38B) having an up and down motion are employed and the pedal arms (38A, 38B) are coupled to the rear wheel (46) by one or two flexible drive cables (42). The cables (42) are wrapped about the rear wheel hub (70) in unsecured relation thereto so that the bicycle (200) may be moved backwardly without damage to the drive cable or to the wheel (46). The ends of the cables are tensioned to prevent the cables (42) from becoming unwrapped from the rear wheel hub (70). Means (43) are provided to permit disassembly of the steering (220) assembly and the front wheel (36) from the frame (32) to provide for ease of carrying and storage of the vehicle (200) when it is not being used. The mechanical advantage in certain embodiments decreases with pedal travel to effectively match the strength of the rider (30) as a function of leg extension.

3.WO/1985/003980COMBUSTION INITIATION SYSTEM EMPLOYING HARD DISCHARGE IGNITION

WO - 12.09.1985

Clasificación Internacional F02P 9/00 Nº de solicitud PCT/US1985/000319 Solicitante PATE, Ronald, C. Inventor/a PATE, Ronald, C.

A system for initiating combustion of fuel, especially for internal combustion engines, employs a very rapid, intense high power electrical breakdown arc to increase the rate of combustion and thereby reduce the need for advanced engine timing. The use of a distribution circuit (46) which has exceptionally low inductance and resistance results in the rapid electrical breakdown and coupling of at least 50% of stored pulse energy to the breakdown arc channel within the first half period of the discharge current cycle. The resulting arc discharge effects detonation of the fuel mixture through the cooperative effects of photolysis, supersonic hydrodynamic shockwave and high temperature thermal plasma. High voltage pulse generation distribution and switching circuits (Figures 29-36) are provided. Several discharge electrode geometres and closely coupled pulse forming networks for the discharge device are disclosed.

Pressurized air for the pumping of a truck tire is lead through a control device comprising a contact manometer (4), an output pumping hose (10), a pair of switching solenoid valve means (16 and 18) and an electric control unit (20) which by means of a repetition rate source means (26) influences upon one of the valve means (16) to successively switching of the lead-out (8) unto the pumping hose (10) between establishing of a connection with a lead-in for pressurized air (6) and with the manometer (4) respectively in such a manner that the manometer reaches to indicate the actual pressure within the tire between the pumping periods wherein the supply of pressurized air is fully opened. A maximum value contact (24) of the manometer serves to switch the first valve means (16) permanently to the manometer connecting condition when a certain overpressure within the tire is attained and to activate the other valve means (18) to successively switching of the lead-out to the pumping hose (8) between establishing of connection respectively with a venting-opening (30) and the manometer (4). An operational pressure contact (22) of the manometer is applied to establish switch-off of the venting when the pressure within the tire is relieved to the wanted operational pressure. The device is in an all automatic manner able to perform a fast and reliable pumping of the tire also when prescribed that pumping shall take place in a manner establishing a certain overpressure and thereafter venting the pressure until the operational pressure within the tire is attained. .
