Patent CA-2321529-A1 (CA)
Inventor: HOYLE SCOTT BAXTER
IPC: G01F1/684
Filed: 2000-10-02
Abstract: An integrated sensor for automated systems includes a flow sensor, a temperature sensor, and a network interface. In a particular embodiment of the invention, the flow sensor includes a temperature sensor (26) which determines the temperature of the fluid flowing in a flow path (12). A heater (18) is coupled to the flow path, and is energized by a controller (20) with sufficient electrical power to raise the temperature of the heater above the measured fluid temperature by a fixed temperature difference. In order to aid in determining the temperature difference, a sensor (24) may be associated with the heater (18). The amount of power required to maintain the temperature difference is a measure of the flow velocity. The volume low rate is the product of the flow velocity multiplied by the area of the flow sensor. The mass flow rage is the product of the volumetric flow rate multiplied by the mass density of the fluid.

Title: Method for removing atm cells from an atm communications device
Inventor: THUDT RAIMAR
IPC: H04L47/36
Filed: 1999-03-23
Abstract: A number of algorithms have been used in prior art to deal with overload situations in ATM transmission systems. One of these algorithms is the known PPD (Partial Packet Discard) method.

IPC: B29C63/34
Filed: 1999-07-29
Abstract: A method of inserting a liner (10) into a host tubular (60), in which the liner is deformed to reduce its cross-sectional dimensions;  the deformed liner is fed into the host tubular in a downstream direction; and a fluid is injected under pressure into the host tubular to urge the liner in the downstream direction, while the fluid pressure maintains the deformation of the liner.

Filed: 2001-06-07
Abstract: A milk basic protein fraction is heated if necessary, the resulting precipitate is removed to recover the resulting supernatant, alcohol is added to this supernatant, a fraction containing a high concentration of milk basic cystatin is recovered by removing the resulting precipitate and brought into contact with a carrier containing a sulfuric acid group, such as heparin, to recover a fraction which is not adsorbed onto the carrier, and this fraction is then treated with an ultrafiltration membrane having an cut-off molecular weight of 10-50 kDa to recover the permeate to produce a fraction containing a high concentration of milk basic cystatin. Alternatively, a milk-derived basic protein composition is brought into contact with an anion exchange resin to recover a fraction which is not adsorbed onto the resin, after which this fraction is brought into contact with a cation exchange resin to recover the target fraction by eluting a fraction which is adsorbed onto the resin with an eluent to produce a fraction containing a high concentration of milk basic cystatin. Further, a decomposition product of the fraction containing a high concentration of milk basic cystatin is produced by decomposing this fraction containing a high concentration of milk basic cystatin with protease.
