Abstract: A structural framework system for the construction of exhibition display stands and the like makes use of a beam extrusion (1) having dovetail shaped edge formations (5) which enable panel frame extrusions (6) to be hung therefrom and locked in position by virtue of the panel frame extrusions (6) incorporating a locking element (15) which can be retracted into a recess (13) in the frame (6) for initial location of the frame (6) relative to the beam (1) and can then be moved to project from the recess (13) and to clamp to the beam dovetail (5) by insertion of actuating pins (20) into bores (16) provided in the frame (6) and, communicating with the recess (13). A beam end fitting (32) enables a beam (1) to be secured to a transversely-extending second beam (1) by a similar process and a 4-way crown fitting (45) enables nodes to be formed at the intersection of plural orthogonal beams. A means (Fig.5) is also disclosed for leg length adjustment and additionally disclosed is a system (Figs. 6-9) enabling attachment of a fabric roof (92) to a frame work structure by virtue of a "foot" (90) secured along the fabric edge being received in a "shoe" (80) provided in the framework.
Patent CA-2294699-A1 (CA)
Inventor: SHAH NAVIN B
IPC: B29C37/00
Filed: 2000-01-11
Abstract: Method for on-mold surface coating fiberglass-reinforced molded articles during their manufacture with environmentally friendly and physiologically safe thermosetting unsaturated polyester on-mold coating powders which serve as replacements for liquid gel coats. The thermosetting coating powders employed are adapted to cure at low temperatures to avoid causing thermal damage to the heat sensitive plastic molds which must be reused over and over again, and to cure in the presence of atmospheric oxygen to enable over coating with liquid fill resins and fiberglass, which constitute the bulk of the finished article, without having the fill resins bleed through the powder coating film and detrimentally affect the overall quality of the surface finish.

Title: Generation of hematopoietic cells from multipotent neural stem cells
Inventor: REYNOLDS BRENT A
IPC: A61K35/12
Filed: 1998-09-28
Abstract: Multipotent neural stem cell (MNSC) progeny are induced to generate cells of the hematopoietic system by placing the MNSC progeny in a hematopoieticinducing environment. The hematopoietic-inducing environment can be either ex vivo or in vivo. A mammal's circulatory system provides an in vivo environment that can induce xenogeneic, allogeneic, or autologous MNSC progeny to generate a full complement of hematopoietic cells. Transplantation of MNSC progeny provides an alternative to bone marrow and hematopoietic stem cell transplantation to treat blood-related disorders.

Patent CA-2308103-A1 (CA)
Inventor: OLARIU GABRIEL
IPC: H04L12/701
Filed: 2000-05-10
Abstract: A load balancing technique for optimally routing data packets to a hybrid terminal over an asymmetric hybrid network link, which utilizes a bi-directional terrestrial channel and a satellite channel. For each data packet received from an Internet server, a load-balancing algorithm is employed to determine whether to route the packet via the bi-directional terrestrial channel or the satellite channel. The load-balancing algorithm is designed so relatively small data packets are transmitted over the bi-directional terrestrial channel, while larger data packets are transmitted over the satellite channel.  All data packets lost during terrestrial transmission are re-transmitted over the satellite channel. Additional value-added services are added to redirect all Internet traffic terrestrially when the hybrid terminal experiences rain fade or other condition, which disrupts the satellite channel.

Patent CA-2312728-A1 (CA)
Title: Reaction time measurement system
Inventor: DEANGELIS DOUGLAS
IPC: A63B69/00
Filed: 1998-11-25
Abstract: A reaction time measurement system includes a hard-wired or battery-powered accelerometer module attached to a starting block or platform to detect acceleration when a contestant moves. Although the block is grossly stationary, it undergoes slight movement and mechanical vibration, so the accelerometer produces an output signal. A filter or a processing unit in the module processes the output signal to define the reaction time or moment when the athlete starts to leave the block.      Preferably the module removably attaches to the starting block by a rigid coupling, and its processor stores and annotates the accelerometer signal. A  link or connector signals the reaction time, or the stored signal on request, to a central monitor at which false start detection determination are made and records created. A speaker may be attached to or included in the accelerometer module to receive a starting signal and produce a start sound at the block, so that the starting blocks at all positions emit the start sound simultaneously. The module may be used as an individual training device, in which a runner's readiness and take-off impulse are analysed as a reaction waveform, or his reaction time and starting speed recorded. For use in a track system, multiple separately addressed modules each annotate the accelerometer signal trace with one or more externally applied or synchronized timing marks. The processing unit may optionally produce a processed output indicating the interval between start signal and the detected reaction time. Preferably the processor also records the sensed acceleration output signal during the period leading up to and surrounding the start signal, and sends the stored measurement data to the monitoring station on request so that the actual acceleration curve may be visually inspected to verify when a false start determination has been made, and the data may be printed out or otherwise stored for the record. The processor may implement any of several detection rules, and threshold reaction times and/or a blanking interval may be set. Upon identification of a false start, the monitor sends an audible alarm and identifies the offending contestant, as well as displaying the time. Several wired and wireless systems provide actual local simultaneous broadcast of a starting gun sound, the immediate detection of a false start, and the identification and verification of infractions without delay.
