Granted: 2000-02-08
Abstract: The distribution-pressurized natural gas is supplied via a conduit (C1) arranged in the piston (P) of an electrovalve (EV) in a nozzle (BG) of which the outlet leads to a cone (C) which provides, with the nozzle (BG), a ring-shaped opening (BA) which, connected to the atmosphere, acts as a secondary nozzle for injecting air into the gas flow. The cone (C) is followed by a cylindrical element (S1) then by an abrupt widening (BC) section (S2) which opens into a heat exchanger (EC) which is in contact with a substrate impregnated with a catalytic material (MC) which oxidizes fuel gas. A small amount of air is sucked up by the widening (BC) and mixed with the gas. This mixture is then treated in the exchanger (EC) up to the transformation temperature of the sulphur-containing compound and the sulphur is then oxidized.

Granted: 1999-03-23
Abstract: A DNA sequence encoding a potato leafroll virus coat protein having at least one internal translation initiation codon in a different reading frame than the native PLRV coat protein DNA sequence altered to a non-initiator codon is provided. Two translation initiation sites at the start of a 17kd open reading frame in a different reading frame than the native PLRV coat protein DNA sequence are preferably altered. A stronger stop codon is also provided in the modified PLRV DNA sequence. The modified DNA sequence having the internal translation initiation codons at the start of the 17kd open reading frame altered to non-initiator codons can be used in a gene to transform plants of the Solanaceae family to obtain transgenic plants resistant to PLRV. A synthetic modified potato leafroll virus DNA sequence is also provided which has the changes in the translation initiation sites and is further made to be more "plant-like". Multiple copies of the modified or synthetic modified PLRV coat protein DNA sequence driven by different promoters have also been transformed into potato with advantageous results. The modified potato leafroll virus DNA sequences of this invention are particularly useful in obtaining transgenic potato plants resistant to infection by potato leafroll virus.

IPC: B31B3/44
Filed: 1993-07-15
Granted: 2003-10-28
Abstract: The mold that belongs to a cardboard box forming machine is comprised of four forming corners, equal to each other, assembled in such a way that they can be moved longitudinally and transversally in order to carry out the adjustment of length as well as width of the boxes to be formed. The adjustment of length is achieved as a result of the corners being assembled on bushings threaded on spindles, each one of the latter having two sections threaded in a different direction so that the rotation of the former involves contrary movement of each pair of forming corners assembled on each spindle. The adjustment of width is achieved on the grounds of movement of said forming corners along linear guides upon which corresponding bridges slide. Forming corners are also completed with means retaining the box during its formation and pressing means for gluing of the corresponding laps.
