Title: Method and apparatus for thermally killing weeds
Inventor: PRULL GREGORY G
IPC: A01M21/04
Filed: 2000-02-03
Abstract: A method and apparatus (10) for thermally killing weeds and other unwanted vegetation from areas where their presence is undesirable. The method and apparatus (10) are especially useful for killing weeds located adjacent auto or rail roadways or airport runways. The method of killing weeds involves first spraying the weeds with an amount of water sufficient to cover a substantial portion of the exposed outer parts of the weeds, and then subjecting the water covered weeds to an elevated temperature sufficient for the time of exposure to kill them. The apparatus (10) for thermally killing weeds by this method includes a water sprayer unit (50) and a heater enclosure or box (20), the water sprayer unit (50) being located in front of the heater box (20). The heater box (20) has burners (44) located at the forward end thereof that impact a heatable element (32) capable of generating infra-red radiation.  A porous apron (23) extends between the bottom (22) of the heater box (20) and the ground to allow exhausting of combustion products and water vapor.

Abstract: L'invention concerne une technique d'injection électriquement induite appliquée à des vaccins d'ADN, qui a permis d'obtenir des réponses immunitaires sensiblement plus importantes. On observe chez les souris et les lapins vaccinés avec de l'ADN codant pour des gènes VIH, des réponses immunitaires jusqu'à vingt fois plus importantes qu'avec des vaccins d'ADN uniquement, lorsqu'ils sont administrés en association avec un courant électrique constant ou une tension électrique constante. L'augmentation a été obtenue dans des conditions de courant constant (ionophorèse) et de tension constante (électroporation).

Title: Method for optimally operating co-generation of electricity and heat and optimally operating district heating power plant
Inventor: VIKSTROM GORAN
IPC: F24D10/00
Filed: 2000-02-24
Abstract: A method for optimally op-erating co-generation of electric-ity and heat in which the district heating power range is divided to a lower range and a higher range is characterized in that: base load electricity and regulation electric-ity are produced with a steam tur-bine operating like a condensing turbine; the lower heating power range (B) is produced mainly by heat pumps using the energy of the exhaust steam of the turbine as an energy source; peak-load power and wintertime regulation electricity are produced with a peak-load engine; and the higher heating power range (A3, A4) is produced partially by heat pumps using said energy as the energy source and partially by the exhaust gas heat of said peak-load engine.  Both the elctricity and the heat are produced with a remarkably higher fuel utilization rate and sig-nificantly more electricity in rela-tion to heat is produced than with conventional district heating power plants. The invention concerns also an optimally operating district heating power plant realizing the above method. At the initial stage of the operation of the district heating power plant, the district heating load being partial, a bigger amount of electricity may be produced of a fuel unit than at the final stage of the operation with a full district heating load. Extra peak power at short notice may be produced with the peak-load engine with a better fuel utilization rate than with the previously known solutions.

Inventor: FUKAZAWA NOBUYUKI
IPC: C07H19/10
Filed: 2001-02-13
Abstract: A mixture of 1-phosphorylated sugar derivative anomers is phosphorolyzed and isomerized to thereby crystallize one of the anomers. Thus, the equilibrium is shifted and a desired isomer alone is selectively produced. From the 1-phosphorylated sugar derivative thus obtained and a base, a nucleoside is produced at a high stereoselectivity and a high yield under the action of a nucleoside phosphorylase. Thus, a process for anomer-selectively producing a 1-phosphorylated sugar derivative and a process for producing a nucleoside are provided.
