The stripped product stream is then sent to the next downstream reaction stage (110b), the product from which is also stripped of dissolved gases and sent to the next downstream reaction stage (110c) until the last reaction stage (110c), the liquid product of which is stripped of dissolved gases and collected or passed on for further processing. The flow of treat gas is in a direction opposite in which the reaction stages (110a, 110b, 110c) are staged for the liquid flow.      Each stripping stage (160a, 160b, 160c) is a separate stage, but all stages (160a, 160b, 160c) are contained in the same stripper vessel (200).

Inventor: BAY RONALD W
IPC: G04F10/00
Filed: 1999-07-05
Abstract: Timer is provided for allowing a teacher to control the absence of a student in a classroom. The timing device has a main body for mounting the timing device in the classroom, at least one signal member located on the main body and arranged to actuate a signal to indicate to the teacher at a predetermined time and an activation and marker member. The student removes the activation and marker member when leaving the class room thus activating the timer and places the marker on the students desk for identification. If the student returns in good time, the student on return replaces the marker on the body thus deactivating the timer on the main body. If the student is overtime, the timer times out to actuate the signal if the marker is not returned within a predetermined time. A first light indicates when a student is absent. A second signals if the student is overtime.

Patent CA-2293019-A1 (CA)
Title: Device for removing a liquid from capillaries
Inventor: PETERS RALPH-PETER
IPC: B01L3/00
Filed: 1999-12-21
Abstract: Liquid components are separated from a liquid using separation devices, such as filters and membranes, in which capillary forces which retain the liquid component to be separated off in the separation device are effective. If the amount of liquid is only small, it can be very difficult to remove the liquid component to be separated off from the separation device in free and unchanged form. This process step is simplified or facilitated by a wedge-shaped cut-out at the exit end of the capillary or in a columnar body which is in contact with the exit end of the capillary. The radius of curvature of the wedge edge is smaller than the radius of the capillary. The base side of the wedge-shaped cut-out is adjacent to a collecting chamber, in which the separated-off liquid component is collected, and in which the capillary forces are smaller than in the capillary. If interfering capillary forces are still effective in. the collecting chamber, a further wedge-shaped cut-out can be provided at the exit end of the collecting chamber. The device makes it possible to separate off liquid components in the microlitre range.

Title: Secure deterministic encryption key generator system and method
Inventor: FIELDER GUY L
IPC: H04L9/08
Filed: 1998-03-09
Abstract: An encryption key generator (100) is disclosed which is highly resistant to cryptographic analysis or brute force attacks, and which accommodates the destruction of an encryption key after each use by providing for the recreation of the key without need of key directories or other encryption key storage processes. A constant value (51) and a secret E-Key Seed (50) are applied as an input to a bit-shuffling algorithm (52) to provide a first many-to-few bit mapping and produce a first pseudo-random number. The first pseudo-random number in turn is applied as an input to a secure one-way hash algorithm (53) to provide a second many-to-few bit mapping and produce a second pseudo-random number or message digest that may be truncated to a desired bit length to serve as a non-predictable but deterministic encryption key (55). Same constant value (51) and E-Key Seed (50) inputs to the key generator (100) provide the same message digest and hence the same key (55).

Title: On-line synthesis with an immobilized enzyme cascade
Inventor: MARKOGLOU NEKTARIA
IPC: C12N11/18
Filed: 2000-05-26
Abstract: The present invention relates to the use of multiple immobilized enzyme reactors (IMERs) in a liquid chromatographic system to perform enzymatic transformations and compound synthesis. The system is characterized by the utilization of separate IMERs and therefore constitutes a modular approach to multiple on-line synthesis. Individual IMERs can be added, subtracted or replaced to meet the requirements of a chosen synthetic plan. The system can be used for designed synthetic pathways or to mimic natural biosynthetic processes. Alternatively, the system as a whole, or each IMER separately, can be used for the discovery and characterization of new drug candidates. The present invention is exemplified by the synthesis of individual IMERs in the biosynthetic pathway that converts tyrosine to epinephrine.
