Patent CA-2308690-C (CA)
Title: Extruder die head
Inventor: LINKIES JURGEN
IPC: B29C48/10
Filed: 2000-05-12
Granted: 2007-07-17
Abstract: An extruder die head for producing multilayered tubes made of thermoplastic material includes a central annular channel, which is provided with an annular outlet. Annular slits in the walls of the channel are used to feed a polymer melt into the annular channel. The annular slits constitute the smaller diameter openings of tapered channels, formed in the internal and external surfaces of pairs of stacked, conical rings. To reduce the axial length of the extruder die head, the annular slits, through which the polymer melt passes, also empty into the inside wall of the central annular channel. The shortened flow path of the melt reduces melt degradation problems associated with prolonged heating, and reduces the stress at melt interfaces.
Patent CA-2312728-C (CA)
Inventor: BARTON ANDREW
IPC: G01P15/00
Filed: 1998-11-25
Granted: 2001-08-28
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 determinatio n 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 ti me 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 withou t delay.

Title: Truck rear door opening mechanism
Inventor: VADER SCOTT J
IPC: E05F1/10
Filed: 2000-09-25
Granted: 2009-02-03
Abstract: A four bar link is provided between a walled cargo area of a truck and a rigid rear cargo door. The effective length of the lower link of the four bar linkage is longer than that of the upper link such that the motion of the door is generally up and over the top of the truck body. An eccentric cam is joined to the upper link with a tensioned spring extending around the cam such that the spring slackens as the door opens. The cam is configured so that, as the door is opened, the spring slackens more slowly initially then more quickly. This allows the door to be moved initially mostly outwardly before moving significantly upwardly and still be effectively counterbalanced throughout its motion.

Abstract: The present invention provides for lipid:nucleic acid complexes that have increased shelf life and high transfection activity in vivo following intravenous injection, and methods of preparing such complexes. The methods generally involve contacting a nucleic acid with an organic polycation to produce a condensed nucleic acid, and then combining the condensed nucleic acid with a lipid comprising an amphiphilic cationic lipid to produce the lipid:nucleic acid complex. This complex can be further stabilized by the addition of a hydrophilic polymer attached to hydrophobic side chains. The complex can also be made specific for specific cells, by incorporating a targeting moiety such as a Fab' fragment attached to a hydrophilic polymer.  The present invention further relates to lipidic microparticles with attached proteins which have been first conjugated to linker molecules having a hydrophilic polymer domain and a hydrophobic domain capable of stable association with the microparticle, or proteins which have been engineered to contain a hydrophilic domain and a lipid moiety permitting stable association with the microparticle.

Filed: 1999-10-15
Granted: 2005-07-12
Abstract: A bottled water/tap water cooler and compact oxygen generator system (100) combined within a single housing structure (10). The oxygen generator (100) includes an air compressor (300) for generating compressed air having into dual molecular sieve beds (120, 130) one at a time. As a first molecular sieve bed (120) absorbs nitrogen, up to approximately 95 % pure oxygen is allowed to pass therethrough to a flow meter (50) and into a diffuser (30) which passes the oxygen into a purified drinking water reservoir (20) supplied by the bottled water or filtered tap water. After the first molecular sieve bed (120) is full, the second molecular sieve bed (130) activates and starts absorbing nitrogen while allowing oxygen to pass therethrough, simultaneously, nitrogen is vented from the first molecular sieve into the atmosphere. The first and second molecular sieve beds alternate with one another allowing the system to run continuously by using timer controlled dual 3-way valves (113, 115).

IPC: B01D65/10
Filed: 2000-11-15
Granted: 2009-01-20
Abstract: A filtering element has ultrafiltration or microfiltration hollow fibre membranes extending horizontally between a pair of opposed horizontally spaced, vertically extending headers. Side plat es extending between the pair of vertically extending headers define a vertical flow channel through the element. Modules are created by placing the elements in place without obstructing the vertical flow channels. Each element may be released from the frame, however, and removed by sliding it in a direction substan-tially normal to its headers without disassembling the remainder of the module. The elements have associated releasable water tight fittings between the elements and a permeate collector, the releasable water tight fittings being releasable by removing an element from the frame. An aerator below the module has a plurality of air holes located to provide a line of air holes below each element or below a side plate between each pair of elements. In a preferred process, permeate flux is less than 50 L/m2/h and preferably less than 35 L/m2/h, aeration to scrub the membranes is provided during periods o f time when permeation is periodically stopped and accumulated solids are removed by periodically emptying and refilling a tank containing the elements. A bubble point test is applied to each row of the module in turn, the presence of bubbles in a particular flow channel indicating which, if any, elements of a row are suitable.
