Patent CA-2019945-A1 (CA)
Inventor: MELLEM JOACHIM
IPC: D04H1/4209
Filed: 1990-06-27
Abstract: ABSTRACT OF THE DISCLOSURE          In the continuous production of mineral wool fleeces, fibre-/ gas-/ air- mixtures (3,4), which are produced by several defibration units (14 to 17), are directed onto collector conveyor units (19, 21) with curved suction surfaces, which are under suction pressure (c, d), for the formation of a wool fleece (25).  Here the arrangement is done in such a way, that each fibre-/ gas-/ air- mixture, which is formed by the individual defibration units (14 to 17), is assigned to an imaginary suction surface, which increases in size in the direction of the movement of the conveyor, namely d > c.  It is thereby possible, under constant suction pressure to produce mineral wool fleeces of good production quality from rock wools with gross densities of even less than 25 kg/m3 per collector conveyor unit in a space saving construction method.  Furthermore, composite webs of felt can be formed by several units connected in series or by way of a pendular deposit of a single fleece.

Title: Method and apparatus for reducing vibration in the press section of a papermaking machine
IPC: D21F3/04
Filed: 1990-09-14
Abstract: Method and apparatus for reducing vibration in the press section of a high speed papermaking machine.  The press section has at least one dewatering felt with means such as a trade line for indicating the orientation of the felt in the press section.  The press section includes means for adjusting the trade line orientation as the felt cycles in a continous loop through the press section.  Barring of the felt, i.e., introduction of thickness variations in the felt by resonant vibrations in the nip, is minimized by progressively altering the trade line orientation as the felt cycles through the press section, the trade line orientation adjustment being accomplished at a rate adequate to iron out bars formed on previous passes and prevent resonant buildup of bars in the felt during operation of the papermaking machine.

Patent CA-2033753-A1 (CA)
Inventor: WANG YANK
IPC: H01J49/26
Filed: 1991-01-08
Abstract: An exact three-dimensional rotationally symmetric quadrupole field or an electric field of higher multipole moments can be generated by closed boundaries with continuously varied potential, especially with linearly variable potential, in the ideal case by simple cone-shaped boundaries with linearly variable potential. An example for the application of the field is storage of charged particles inside the closed boundaries. Within the same cone-shaped boundaries, a homogeneous ideal field in the direction of the symmetry axis can be superimposed. This field can be employed for excitation of the kinetic energy, for quenching, or for energy analysis of the stored charged particles. For the generation of mass spectra the mass-to-charge specific fundamental frequencies of the charged particles stored in the electrode structure are excited. The image currents induced in the electrode structure are frequency analysed (e.g. by Fourier transform).

Abstract: There is disclosed a garbage disposer which pulverizes kitchen garbage, drys it and discharges only the yield water into a sewage system. This apparatus includes a garbage pulverizing segment and a garbage drying segment, both of which are driven by a common motor. The garbage drying segment includes a screw with a helical blade and a cylindrical screen disposed around the screw. In this garbage drying segment the garbage is compressed and dried as it is pressure-fed by the screw within the screen. The water thus produced flows past the screen and is discharged from the garbage drying segment into the sewage system, while the dried garbage is collected in a bag.

Abstract: A shaft furnace for melting solid copper into molten copper has so far been controlled by manual operation with reference to the actual storage quantity of the building furnace.  The burner air pressure of each zone of the shaft furnace is controlled by the actual storage quantity and the time change of it using Fuzzy Logic.  The temperature of the molten copper is adopted as another input signal.          The proportion of burner air pressure of the zones is revised by the temperature of the molten copper.  Automatic control based upon the present invention decreases the fluctuation of the storage quantity of the holding furnace.

Title: Methods and compositions for isolation of nucleic acids from eukaryotic and prokaryotic sources
Inventor: KOLLER CHARLES A
IPC: C12N15/10
Filed: 1990-08-14
Abstract: The present invention relates to methods and compositions for isolation of nucleic acids from cells. In particular aspects, this invention relates to the use of chaotropic compositions, such as guanidine hydrochloride or guanidinium isothiocyanate, in combination with polyanionic compositions, such as those containing sulfated polysaccharides (i.e., heparin or heparitin sulfate), for the isolation of nucleic acids (RNA and DNA). This method involves disrupting and lysing cells using a nucleic acid releasing composition containing a chaotropic component for the release of nucleic acids from the cell (guanidine hydrochloride or guanidinium isothiocyanate). The released nucleic acids are collected by ethanol precipitation and resuspended before exposure to a polyanion-containing protein dissociating composition which promotes the dissociation of nucleic acid associated proteins from the suspended nucleic acids. The isolated nucleic acids are washed, further collected by ethanol precipitation and resuspended in a selective buffer prior to further use.

Abstract: ABSTRACT                      Resealable Packaging Material The invention is a flexible packaging material having a narrow side band (10) of pressure sensitive adhesive (14) beneath a heatsealable surface layer (12).  When the material is formed into a package, a heatseal (30) is formed along the side band of pressure sensitive adhesive.  When the heatseal is opened, the pressure sensitive adhesive becomes exposed at the surface of the seal, which enables the package to be resealed by manual pressure alone.  A particular advantage of the invention is that the pressure sensitive adhesive is present only where it is needed to form the resealable seal.  The packaging material is made by side-by-side coextrusion.
