Patent CA-2033181-A1 (CA)
Title: Two valve micropump with improved outlet
Inventor: VAN LINTEL HARALD T G
IPC: F04B43/00
Filed: 1990-06-12
Abstract: Pumping takes place within the micropump as a result of the deformation of a plate (12) using a piezoelectric pad (13). The deformation produces a variation in volume within a pumping chamber (15) defined inside a plate (11) which is made of a material which can be machined using photolithographic processes. The pump outlet (3) is blocked off, selectively, by a membraned check-valve (18) which is in direct communication with another check-valve (16) via the pumping chamber. The check-valve (16) selectively enables the pumping chamber to communicate with the pump inlet (2). The outlet valve membrane (18) has a layer of oxide (17) providing a pretension on closing. The check-valve thus has a regulatory effect on the pump operation, making the flow almost independent of the outlet (3) pressure.

Filed: 1991-06-18
Abstract: ABSTRACT      A method of delignifying comminuted cellulosic fibrous material (paper pulp) at a consistency of about 30-45% employing ozone as the active bleaching component, and capable of utilizing a variety of different reactor designs.  In each case the paper pulp is fluffed and ozone gas is added to it, and the pulp is maintained in contact with the ozone containing gas while it is tumbled to keep it loose, and homogenous, with a high surface area to volume ratio.  The reactor may be just below a fluffer, or the pulp may be pneumatically conveyed to the reactor.  The reactor may include a screw having lifters on the screw flights, or paddles extending radially outwardly from the screw shaft; or a short screw section may be provided only adjacent the pulp inlet and radially extending paddles provided along the rest of the length of the shaft.  The paddle distal tips have a tangential velocity sufficient to impart a ballistic velocity to the pulp such that the arc described by the particles follows the arc of the vessel shell.  Alternatively, tumbling may be provided by rotating a tubular reactor shell about an axis which slants downwardly with respect to the horizontal.   Lifters may be provided extending inwardly from the inner circumferential periphery of the rotating shell.  The lifters usually being provided just at the discharge end of the shell to lift the treated fluffed pulp into a discharge mechanism.

Title: Article coating system
Inventor: SALISBURY RICHARD
IPC: B05B15/12
Filed: 1990-02-01
Abstract: A system for coating articles by the use of electrostatic attraction of ionized particles which are subsequently cured. The system includes a pair of carriers for jointly carrying each article through the system, from application of the particles to the article through curing of the particles on the article. Each carrier is capable of carrying the article independently of the other. After deposition of the particles on the article the article and the carriers are conveyed through a cleaning station wherein one of the carriers is moved out of carrying engagement with the article and cleaned while the article supported by the other carrier. The other carrier is then moved out of supporting engagement with the article and cleaned while the article is supported by the first carrier. The system also includes a spray booth for depositing the particles on the article which limits the exposure of the carriers to the spray of particles and includes a removable replaceable insert to eliminate the need for cleaning the spray booth when there is a change in the nature of the particles being used, such as color.

Inventor: OZAWA KAZUNORI
IPC: G10L19/16
Filed: 1992-02-25
Abstract: A speech parameter coding method and apparatus which can quantize a spectrum parameter of a speech signal with a smaller number of bits than ever.  A dividing section divides a predetermined order number of spectrum parameters, obtained by division of a speech signal into frames, for each order number of spectrum parameters smaller than the divisional order number.  A vector quantizing section searches codebooks for the divided spectrum parameters for each order number and outputs a plurality of candidates of codevector in order of magnitude from the minimum one.  An accumulated distortion calculating section calculates accumulated distortions for the entire order number for combinations of codevectors.  A minimum judging section selectively outputs a combination of codevectors which minimizes the accumulated distortion thereby to quantize the spectrum parameter.
