  • Process for making an annular abrasion bead element for a cutting wire for cutting relatively hard materials
    Publication number: 20070194492
    Abstract: The present invention relates to a process for making an annular abrasion bead element for a cutting wire for cutting relatively hard materials, comprising the following sequential steps: loading a mixture of metal material powder and abrasive granular material into at least one annular seat of a first mold; forming said mixture in said mold, thus obtaining at least one formed annular element with inner through opening (5); and sintering each formed annular element to obtain a finished annular abrasive element.

  • Gene expression in biological conditions
    Publication number: 20060240426
    Abstract: The present invention relates to a method of predicting the prognosis of a biological condition in animal tissue, wherein the expression of genes is examined and correlated to standards. The invention further relates to the treatment of the biological condition and. an assay for predicting the prognosis. In particular, the invention concerns gene expression in epithelial tissue, such as urinary bladder under both normal and abnormal conditions.

  • Gene expression in bladder tumors
    Patent number: 6936417
    Abstract: Methods for analyzing tumor cells, particularly bladder tumor cells employ gene expression analysis of samples. Gene expression patterns are formed and compared to reference patterns. Alternatively gene expression patterns are manipulated to exclude genes which are expressed in contaminating cell populations. Another alternative employs subtraction of the expression of genes which are expressed in contaminating cell types. These methods provide improved accuracy as well as alternative basis for analysis from diagnostic and prognostic tools currently available.

  • Device system for multiple motors
    Patent number: 6815915
    Abstract: A device for supplying energy by means of a first DC voltage source e.g. in the form of a DC voltage bus, a drive system comprising several electric motors is connected to said DC voltage bus. The electric motors are comprised e.g. in a number of yarn feeding devices co-acting with a weft insertion system in a shuttleless weaving machine for producing a woven fabric having a multi-colour pattern. The electric motors operate with energy consumption function phases (start and acceleration) and with energy generating function phases (deceleration or braking). The first DC voltage source is associated with at least one second DC voltage source via a variable voltage converter.

  • Electric motor device for powering a tool clamp
    Patent number: 6479783
    Abstract: An electric motor device for powering a tool clamp, for example a resistance welding clamp, of the type comprising a casing of an electric motor 4 the shaft of which is connected to the clamp, to control the electrodes for opening, closing and clamping them onto a metal sheet, by a system of the through-the-motor type which converts the rotary motion of the shaft into translational motion of a mechanism 5 operating the clamp, this motor being linked to a control variator and a slaving device 10 coupled to the rotor of the motor. The device 10 being arranged at the end of the motor shaft, the shaft is fitted with a gear wheel 14 which can be operated from the outside, for rotating it manually, through at least one opening 15 in the casing offset with respect to the motor shaft.

  • Actuator with approach pre-stroke and working stroke for operating a tool
    Patent number: 6474215
    Abstract: The invention concerns an actuator (21) comprising a pre-stroke rod (29) which can be fixed to the tool body, for example soldering pliers. Thus by pressurising the pre-stroke chamber (27) the working rod (34) for closing the pliers can be brought into an intermediate small opening position, the working piston (31) and the amplifying pistons (36 and 37) remaining retracted in the actuator. Since the rod (29) can then be locked relative to the actuator body (21), pressurisation of the working chamber (32) and the amplifying chambers (38 and 40) will then cause the working rod to be extracted (34) and the soldering pliers to be closed without any recoil from the actuator body.

  • Method for automatically selecting the welding sequence for manual welding electrode holders; manual welding electrode holder for implementing the method
    Patent number: 6337458
    Abstract: The electrode holder comprises a body 1 suspended by an articulated link 9, 13, 14 from a sling 6, this articulated link comprising a pivot collar 13 in which the body can rotate around a principal longitudinal, swiveling axis X and a pivot 14 mounted on this collar and by means of which the body 1 can pivot on the end of the sling 6 around a horizontal lateral axis y perpendicular to axis X. The body 1 is integral with an inclinometer giving the value and sense of the angle of pivot of the body around the principal axis X, and of the lateral axis y in relation to a reference vertical. This information is used to identify the welding location and to automatically select the appropriate welding sequence corresponding to this location. This sequence is coded and transferred to a welding control cabinet to be executed.

  • Method of electrically welding a part such as a screw or a bolt onto a bore in a composite metal sheet
    Patent number: 6294751
    Abstract: A method of electrically welding a part such as a bolt around a bore of a composite sheet comprising an intermediate layer of a substantially insulating material disposed between two metal layers. Said sheet is pre-heated in the vicinity of said bore in order to remove said substantially insulating material therefrom, after which said part is welded onto said sheet by a conventional resistance spot welding method. Preferably, said pre-heating operation is conducted by passing an electric current between a counter-electrode applied to the sheet from the same side as said part to be welded, in the vicinity of said bore, and an electrode applied on said part to be welded.

  • Cylinder with an elastic device for returning a working piston unit to a neutral position
    Patent number: 6283011
    Abstract: This cylinder, which may be entirely pneumatic, has two working pistons 26 and 27 linked to a working rod 28, slidably mounted on which are two small auxiliary pistons 37 and 38 which can be displaced in an auxiliary chamber 35. The latter, being permanently supplied with a compressed gas, can cause the return, by means of the piston 38 or 37, of the fitting 26-27-28 to an intermediate position shown in the drawing, respectively from a fully extracted position (towards the right) of the rod 28 or a fully retracted position (to the left) of this rod.
