Patent CA-2263227-A1 (CA)
Inventor: WALTERS MICHAEL R
IPC: B04B5/04
Filed: 1999-02-26
Abstract: A carrier tube system and method for using the same includes a carrier tube that is configured to receive a capillary blood tube, and a cap which seals the carrier tube to isolate the blood in the capillary tube from the surrounding atmosphere. The carrier tube system can be placed in a centrifuge which separates the blood with its component parts and optically reads the resulting layer thicknesses. The cap of the carrier tube can include a gear portion which is adapted for engagement with an indexing mechanism of the centrifuge, so that the indexing mechanism can rotate the carrier tube system about its longitudinal axis during centrifugation, thus allowing the optical reader of the centrifuge to take layer thickness readings at various positions about the circumference of the capillary tube. The cap can also include a float holder which holds a float that is inserted automatically into the capillary tube when the cap is placed

Title: Safety joint
Inventor: MCGARIAN BRUCE
IPC: E21B17/06
Filed: 1997-09-25
Abstract: The present invention relates to safety joints which permit separation of a downhole assembly at the location of the joint. The invention provides a safety joint characterised by the provision of auxiliary interconnecting means on a body (2) for interconnecting said body (2) to an auxiliary shaft after removal of a main shaft (3) from said body (2). Axial loading between the auxiliary shaft and said body (2) may be thereby transferred. Furthermore, torque may also be transferred between the auxiliary shaft and said body (2) in a direction opposite to that in which torque may be transferred from the main shaft (3) to said body (2). Thus, the present invention allows a length of downhole assembly located above said body (2) to be removed from a wellbore by rotation of said length of assembly in a first direction and then allows rotation of said body (2) in the same first direction by means of the auxiliary shaft in an attempt to remove a length of assembly stuck in the wellbore downhole of said body (2).

Title: Partial autocausticization of alkali liquors for wood pulping processes
Inventor: TRAN HONGHI N
IPC: D21C11/00
Filed: 1999-05-31
Abstract: A method is provided for the use of borates in the recausticization of alkali- containing liquors such as those produced in the chemical and semi-chemical pulping of wood and in the oxidation and bleaching of wood pulp. Sodium hydroxide is regenerated from sodium carbonate-containing smelts in such pulp processes by autocausticization through the addition of limited amounts of borate. Autocausticization may be carried out at boron to carbonate molar ratios below 2:1 and at sodium to boron molar ratios exceeding 3:1, resulting in high reaction efficiency. Partial autocausticization using borate may also be combined with conventional lime recausticization for the regeneration of sodium hydroxide from sodium carbonate-containing smelts.

Inventor: FLADDA GERDT
IPC: D21C9/10
Filed: 1998-12-22
Abstract: The invention relates to a method and a device for measuring the amount/activity of the enzyme catalase before or in connection with bleaching of cellulose fibres preferably in a pulp suspension for the purpose of providing a better and more uniform product quality and a correct dosing of the actual bleaching substance during the bleaching. According to the invention a measurement sample is derived from a predetermined volume of the pulp suspension after or during the bleaching. Further, a determined amount of bleaching substance is added to the sample, which is agitated so that the bleaching substance is decomposed and oxygen gas is generated, which oxygen gas pushes out a certain sample volume from the measurement sample, which sample volume is measured after a determined time and is directly or indirectly converted, e.g. via a simple algorithm, to a value representing the actual amount of catalase.

Inventor: ARAVAMUDAN MURALI
IPC: H04M3/56
Filed: 1999-10-06
Abstract: A conference bridge is selected for a conference call so as to reduce the overall cost of the conference call, and the conference bride selected may be changed dynamically, e.g., as parties are added or dropped from the conference call, so as to continuously maintain the low cost of the conference call. User telephones are connected via device servers, which may include a packet circuit gateway (PCG), to a packet network which provides both transport and service. Accordingly, in response to a request for a conference call, the packet network determines the parties to be on the conference call and selects a conference bridge that results in the lowest cost for the conference call, e.g., a bridge located more closely to two of the parties on the conference call. In the event the parties on the conference call change, e.g., by adding an additional party and possibly also by dropping a party already on the call, a new conference bridge is selected for the call that would keep the cost low for the call as configured with the revised parties and the information streams from all of the parties that remain on the call are directed the new conference bridge. Once the transition to the new conference bridge is completed, the old conference bridge is released for use by another conference.

Abstract: This invention provides method and apparatus for ancillary data in a wavelength division multiplexed (WDM) system. According to the invention, a low bit rate channel is provided over a amplitude modulated sub-carrier that is in turn used to amplitude intensity modulate an optical data signal that is output from a transmitter in the network. Data carried by the low bit rate channel can by used by another network element (NE) to determine the identity of the channel source, thereby allowing the NE to verify its connectivity to that source via the network. This invention is particularly useful in metropolitan optical networks (MON) where inexpensive methods of determining network connectivity are required.

Abstract: A projectile (40, 60) for an industrial ballistic tool is formed from zinc or a zinc based alloy. The projectile has symmetry about a longitudinal axis (12) and a rear portion of the projectile engages rifling (80), either within the barrel of the industrial ballistic tool or in a rifled extension (74), imparting ballistic stability.      The projectile (40, 60) is particularly suited for high temperature industrial applications, such as removal of "clinkers" from cement kilns or lime kilns or removal of a plug when tapping an electric arc furnace, as used in the manufacture of metallic alloys such as ferrosilicon. The vaporization temperature of the projectile is sufficiently low that after effecting removal of the clinker or plug, the projectile vaporizes and does not contaminate the kiln, furnace or end product such as lime, cement or metallic alloy.
