IPC: B23H7/10
Filed: 1990-08-24
Abstract: The invention relates to a device for wire comminution, with at least one revolving cutter 2 mounted on a rotating cutter support 1. In order to ensure a neat dividing cut of the continuous wire in a reliable mode of operation, provision is made for an opposing tool to be designed in the form of a cutting disc rotating about a vertical axis and provided with a central recess 5, and for the cutter support 1 to be mounted so as to rotate about a second axis 6 parallel to the first axis 4, and for the cutter 2 to be guided along the cutting disc 3. The device can be adapted to different conveying speeds of the wire and permits exact division of the wire into wire sections which are always identical.

Title: Catalyst system for synthesizing trans-1,4-polybutadiene
Inventor: PATTERSON DENNIS BRUCE
IPC: C08F36/06
Filed: 1990-12-18
Abstract: Trans-1,4-polybutadiene is a thermoplastic resin rather than a rubber at room temperature by virtue of its high degree of crystallinity. Because trans-1,4-polybutadiene contains many double bonds in its backbone, it can be blended and cocured with rubbers. It is accordingly an attractive alternative to conventional fillers such as carbon black, which are typically utilized in compounding rubber. By utilizing the catalyst system and techniques of this invention, trans-1,4-polybutadiene can be synthesized at a high level of conversion. This invention specifically relates to a process for the synthesis of trans-1,4-polybutadiene by an anionic polymerization process which comprises: (a) adding an alkali metal trialkylmagnesiate and an alkali metal alkoxide as a catalyst system to a polymerization medium containing 1,3-butadiene monomer and an organic solvent; and (b) allowing the 1,3-butadiene monomer to polymerize at a temperature which is within the range of about -10°C to about 50°C to produce the trans-1,4-polybutadiene.

Abstract: Selon le système d'alimentation en encre de l'invention, la circulation continue d'encre dans une tête à jet d'encre est assurée par deux réservoirs reliés à chaque orifice de jet d'encre (11) par des passages correspondants (40, 15, 13, 42), de sorte que de l'encre s'écoule en continu à partir d'un réservoir à niveau élevé au-delà de l'orifice, jusqu'à un réservoir à niveau bas. La différence entre les niveaux d'encre (45, 46) dans les réservoirs est maintenue relativement constante par un pompage inertiel pendant le mouvement de va-et-vient de ladite tête à jet d'encre, ou par transfert sous pression d'encre d'un réservoir à l'autre réservoir. Une purge par écoulement transversal d'air ou de poussière provenant de ladite tête à jet d'encre est effectuée par couverture des orifices de jet d'encre (11), et par application d'air sous pression à un réservoir afin de provoquer l'écoulement d'encre et d'air ou de poussière piégée, de ladite tête jusqu'à l'autre réservoir. Une pompe réagissant au mouvement de va-et-vient de ladite tête à jet d'encre, produit une pression d'air positive appliquée pendant la purge, ainsi qu'une pression d'air négative appliquée à un désaérateur afin d'éliminer l'air dissous de l'encre.

Title: Method and apparatus for producing an arbitrary excitation spectrum for fourier transform mass spectrometry.
Inventor: GOODMAN SETH
IPC: G01N27/62
Filed: 1990-05-17
Abstract: A desired mass domain excitation profile is selected and converted to a frequency domain excitation spectrum in which the frequency of excitation is generally proportional to the inverse of the mass-to-charge ratio. In the direct method of the invention, the specified frequency domain spectrum is converted by inverse Fourier transformation to a time domain waveform and multiplied by an expanded window function. The time domain waveform is forward Fourier transformed to produce a second discrete frequency spectrum each frequency of which is assigned a phase scrambled such that maximum reduction of peak excitation voltage is achieved with no distortion of the excitation amplitude spectrum. The phase-scrambled frequency spectrum is inverse Fourier transformed to produce the final time domain waveform which is used to generate the electric field which excites the ions in an ion cyclotron resonance cell. In the iterative method of the invention, the desired frequency spectrum is phase scrambled such that all frequencies are not in phase in any point in time, an inverse Fourier transform is performed on the phase scrambled frequency spectrum, and the result multipled by a window function. The time domain waveform is forward Fourier transformed to produce an output spectrum which is compared to a reference spectrum to provide correction factors which are used to predistort the magnitude of the final frequency spectrum, and the steps are repeated until the output frequency spectrum is sufficiently close to the reference spectrum, whereafter the time domain waveform corresponding to that output frequency spectrum is applied as the excitation signal.
