Patent CA-2104164-A1 (CA)
Inventor: GREENE BOYD B
IPC: B01D17/02
Filed: 1993-08-16
Abstract: An apparatus and method for removing particles of a first liquid from a second liquid using Stokes' law, the first liquid, such as oil, having a greater buoyancy than the second, such as water, with both liquids being immiscibly combined into a flowing fluid mixture.  Surges in the mixture's flow are dampened, and the mixture is constrained to have a limited horizontal flow velocity through the tank of the apparatus.  A separator chamber with a plurality of parallel subchannels formed by spaced vertical plates has a geometry that reduces and controls the Reynolds number of the subchannels and controls the velocity through the subchannels, causing the flow therethrough to be substantially non-turbulent.  A first gate inhibits the flow of sediment into the separator chamber.  The flow path length through the separator chamber is such that the particles will have sufficient time to rise above a downstream exit, near the bottom of the separator chamber, and into a holding chamber.          A transverse velocity gradient formed within the subchannels causes the particles to spin and follow a curved path toward the lower longitudinal velocity regions adjacent the walls of the subchannels where the particles agglomerate and rise to the surface.  A vertical rising unit is optionally provided to remove very tiny particles that have insufficient buoyancy to rise above the separator chamber's exit, and various filters may remove other impurities.

Title: Tubing sealer
Inventor: HLAVINKA DENNIS J
IPC: B29C65/00
Filed: 1993-09-02
Abstract: An insulating sleeve retains heat in the plastic of a flexible plastic medical tube when the plastic of the medical tube is dielectrically heated by tubing sealer. The heat retained by the insulating sleeve permits additional melting of the plastic of the medical tube after a seal has been formed. The additional melting results in forming an easily tearable web between the segments of the medical tube in the same operation as the sealing operation. The medical tube is selectively sealed without forming the easily tearable web by using the radio frequency tubing sealing without the insulating sleeve.

Filed: 1994-04-25
Abstract: An active adaptive noise canceller (100) that inserts delays into the weight update logic of an adaptive filter to keep the filter stable.  The noise and residual noise are sensed (102, 108) and the respective sensor signals are digitized at a given sample rate for processing in the adaptive filter (113).  To eliminate the need for high sample rates while maintaining flexibility in the frequency regions over which the adaptive filter is stable, the delay (116) introduced into the weight update logic is a non-integer multiple of the sample period.  The non-integer sample delay (118) is obtained by a sample interpolation and decimation procedure.

IPC: H04K1/00
Filed: 1994-07-18
Abstract: A security node disposed in the telecommunications network connecting calling and called parties transforms information (which can be voice, data, facsimile, video and other types of calls or messages) encrypted in a first format to (a) encrypted information in a different format or to (b) non-encrypted information, and vice-versa. The node is accessible from any location connected to the network. By routing calls or messages originated by the calling party and destined for the called party via the security node, and providing appropriate control signals to the node, the information may be encrypted only over a portion of the transmission path between the parties, and clear over the remainder of the transmission path. Alternatively, the information may be encrypted in different portions of the path using different encryption algorithms. This arrangement enables the parties to obtain relatively secure communications even if only one party has a security device at the originating or terminating end, or if the parties have security devices using different handshaking protocols and encryption algorithms.

Title: Particle classification method and apparatus
Inventor: VENTER CON-VIVIER
IPC: G01N21/65
Filed: 1994-12-28
Abstract: The invention concerns a method and apparatus for classifying particles, and in particular for classifying particles according to whether they are diamond or non-diamond particles. In the method each particle (24) is irradiated with a pulse of monochromatic light capable of causing Raman spectral activation in certain particles. Light emitted by the particle is filtered to remove components which are outside a band including a characteristic Raman spectrum for the relevant class of particles. The filtered light is direct onto a light sensitive switch (26) which is arranged to close on receipt of filtered light of predetermined intensity. On closure of the light sensitive switch, an electrical pulse is generated and directed towards a pulse detector (32). The particle is classified according to whether or not the pulse detector (32) detects an electrical pulse within a predetermined time window. The original pulse of monochromatic light can be split into a test portion, used to irradiate the particle, and a control portion used to control a time gating apparatus which sets the time window. The method can be used in a particle sorting method in which, typically diamond and non-diamond particles are separated from one another.
