Title: Change fitting for process measurement point
Inventor: SCHNEIDER JOSEF
IPC: G01D11/30
Filed: 2000-08-16
Abstract: A change fitting for exchanging a measurement transducer in a measurement chamber, which allows the measurement transducer to be removed for repair under process conditions. The change fitting comprises a first passage, which is located in the wall of the measurement chamber and through which the measurement transducer can be inserted into the measurement chamber, and a second passage, which is located in the wall of the measurement chamber and in which a protective pipe can be moved onto the measurement transducer and to create a seal between the measurement chamber and the space around the measurement transducer. It is thus possible to remove the measurement transducer for cleaning and maintenance without having to interrupt process operation.
Patent CA-2320146-A1 (CA)
Title: Telecommunications platform
Inventor: DANIELS IAN GEOFFREY
IPC: H04M11/00
Filed: 1999-02-08
Abstract: A telecommunications data conferencing platform has a secure zone (10) and a partly secure zone (12) connected by a secure firewall (14). The secure zone (10) contains a master data server (16), a billing system (18) a reservation system (20) and an audio bridge (22) connected to the firewall (14). The partly secure zone (12) contains a pair of slave data servers (30 and 32). The slave data server (32) can be connected through a public firewall (38) to the public Internet (44). The slave data server (30) can receive incoming calls from the public switched telecommunications network (28) via a bank of modems (50).  The secure firewall (14) restricts the passage of messages from the party secure zone (12) to the secure zone (10) to messages which originate directly in the party secure zone (12) but allows the passage of conference data. Thus, unauthorised parties are unable to gain access to the reservation system (20) or the master data server (16). In order to establish a conference, the reservation system (20) creates a conference on the master data server (16). The master data server (16) then invites the slave data server (30 and 32) to join the conference. The slave data servers (30 and 32) then permit participants to join the conference.
Patent CA-2322580-A1 (CA)
Inventor: VAN NIEUWENHOVEN MARCEL
IPC: G11B27/32
Filed: 1999-12-21
Abstract: In a method of recording real-time information on an information carrier, e.g. audio on an optical disc, the real-time information is compressed to units comprising a variable amount of compressed data, and playback parameters are determined in dependence of the compressed data. The playback parameters comprise an access list (Main_Acc_List) having entries, each subsequent entry being assigned to a subsequent interval of a fixed playback time and comprising a pointer (Entry¢N!) to a unit within said interval. In a player the real-time information may be accessed at a selected point of playing time. The corresponding entry in the access list is determined by dividing the selected time by the interval. The entry provides the pointer (Entry¢N!) to the unit corresponding to the selected playing time. Interpolation may be used for calculating an address at a selected playing time within an interval, and the accuracy may be improved by a margin parameter (Access_Flags¢N!), which indicates the maximum distance between the unit of the selected playing time and the interpolated address.

Patent CA-2331893-A1 (CA)
Title: Fabrication of gallium nitride semiconductor layers by lateral growth from trench sidewalls
Inventor: DAVIS ROBERT F
IPC: C30B29/38
Filed: 1999-06-09
Abstract: A sidewall (105) of an underlying gallium nitride layer (106) is laterally grown into a trench (107) in the underlying gallium nitride layer, to thereby form a lateral gallium nitride semiconductor layer ( 108a).  Microelectronic devices may then be formed in the lateral gallium nitride layer. Dislocation defects do not significantly propagate laterally from the sidewall into the trench in the underlying gallium nitride layer, so that the lateral gallium nitride semiconductor layer is relatively defect free. Moreover, the sidewall growth may be accomplished without the need to mask portions of the underlying gallium nitride layer during growth of the lateral gallium nitride layer. The defect density of the lateral gallium nitride semiconductor layer may be further decreased by growing a second gallium nitride semiconductor layer from the lateral gallium nitride layer.

Patent CA-2335092-A1 (CA)
Inventor: VISSER JAN W M
IPC: C12Q1/6876
Filed: 1999-07-28
Abstract: There is provided a method for detecting and/or differentially identifying long-term repopulating hematopoietic progenitor cells. The method comprises detecting expression of tissue transglutaminase, which is uniquely expressed by long-term repopulating cells among blood or marrow cells. Thus, the method can comprise, for example, detecting the expressed protein, detecting an mRNA  encoding the protein, or detecting an enzymatic metabolite of the protein.  There is also provided a method for isolating long-term repopulating hematopoietic progenitor cells, comprising contacting cells from a sample of blood or marrow with an immobilized probe that selectively binds to tissue transglutaminase, to bind the long-term repopulating cells, and then collecting the bound cells. The selective identification or isolation of such long-term repopulating hematopoietic progenitor cells provides specific advantages, including the potentiation of allograft procedures, marrow reconstitution following myeloablation, and similar serious medical procedures.

Title: Drain pump mounted pressure switch for a washing machine
Inventor: HANSEN TED L
IPC: D06F39/08
Filed: 2001-04-25
Abstract: The air pressure sensor of the present invention functions to control the water level in a washing machine tub and to vary the fill volume relative to the clothes load. The sensor or switch is mounted on the drain pump on the base of the washing machine cabinet, so as to be independent from the washing machine tub.      An air dome extends between the switch and the water inlet line of the pump. The switch is set to be actuated at a predetermined pressure. As the water level increases in the tub, the air pressure within the air dome increases, until eventually the switch is actuated. The switch is mounted directly to,the air dome in an angular orientation, thereby minimizing or eliminating condensation problems in the switch. The switch will also be activated by water pressure, in the event of an air leak in the air dome, so as to preclude water overflow of the tub.
