The present invention proposes a cutting machine comprising: a cutting mechanism, a hitch structure able to be raised relative to the ground, a carrier beam connected to said cutting mechanism by means of a first pivot articulation and to said hitch structure by means of a second pivot articulation, an operating member intended to pivot said cutting mechanism from a working position to a transport position, a limiter device intended to limit the pivoting of said cutting mechanism so as to stop it in an intermediate position when said operating member is actuated, and a device intended to automatically render said limiter device inactive when said hitch structure occupies a raised position relative to the ground.
摘要:
The present invention concerns the development of a quantitative method for the molecular diagnosis of autosomal recessive spinal muscular atrophy (SMA) by measuring the amount of cytosolic mRNA from human muscle cells. Both the procedure using radioactive material and the Enzyme-Linked Immunosorbent Assay (ELISA) nonradioactive method were developed using 32P-dCTP labeled and biotinylated nucleotide probes. The results obtained demonstrate that the measurement of mRNA could be used as a quantitative method for the molecular diagnosis of SMA. There was a perfect concordance of the results obtained between the procedure using radioactive material, the ELISA method and the single strand conformation polymorphism (SSCP) analysis regarding the negative and positive SMA samples. The methods developed in this study may be applicable to the diagnosis (detection of homozygous and heterozygous deletions in exons 7 and 8 of the SMN gene) and the control of mRNA concentrations in the future gene therapy of patients with SMA.
摘要:
A mower which is to be coupled to a motor vehicle comprises a first cylinder acting directly or indirectly on a deformable structure, which is in direct connection with a second fluid cylinder whose length varies, from a certain value, proportionally to the pivoting of a mowing group around an axis of a joint which connects the mowing group to a support beam of a frame.

A mower includes a supporting structure that can be coupled to a tractor and bears a support beam to which there is articulated a cutter bar that can be brought from a work configuration into at least one transport configuration and vice versa using an unfolding and folding device. The unfolding and folding device includes a tilting element connected to the support beam and to the supporting structure, a link rod connected to the cutter bar, a double-acting jack positioned between the tilting element and the link rod.
摘要:
A cutting device including a gearbox of an upper part, a lower part, and a front piece, the front piece having a thickness greater than the thickness of the upper part. At least one guide bearing is connected to the gearbox by assembly elements. At least one cutting member is connected to the gearbox by the guide bearing, the cutting member being driven in rotation during work about an upwardly directed axis. And, at least one assembly element is anchored in the front piece of increased thickness, attachment of the guide bearing being thus improved.
摘要:
A cutting device includes a cutting mechanism, a hitching structure designed to be connected to a motor vehicle, a support beam joined to the hitching structure and to the cutting mechanism and a traction device. The traction device is comprised of at least one draw-spring designed to lighten the cutting mechanism during operation and a control device designed to void the action of the at least one draw-spring when the cutting device is placed. The control device has, among other things, a rod at one of the ends to which the at least one draw-spring is attached. The control device is comprised of a cylinder which has the rod, a body, a piston which separates the body into first and second chambers, and a fluid circuit which has a device which allows the fluid to enter the first chamber located on the side of the at least one draw-spring when the latter must be tightened, and allows the fluid to leave the first chamber when the at least one draw-spring must be relaxed.
