Patent CA-2307987-A1 (CA)
Inventor: DAVIS GARY R
IPC: F17C13/08
Filed: 2000-05-10
Abstract: A composite laminated generally cylindrical container for over-the-road transportation of liquids by truck is fabricated using a core of cellular thermoplastic expanded foam material, with an encapsulating layer adhered to each of the interior and exterior surfaces. The encapsulating layers of the cylindrical portion each utilise at least one layer of resin-impregnated unidirectional filament material, with the primary filaments extending in the longitudinal direction to provide bending strength, and a plurality of layers of spirally wound, resin-impregnated filaments to resist shear, torsion and external and internal pressure. The core and the encapsulating layers define a bonded sandwich type of construction. The container can be supported only at its forward and rearward ends during over-the-road transportation of liquids, like presently available stainless steal containers.

Title: Circuit interrupter with non-symmetrical terminal collar
Inventor: MUELLER ROBERT W
IPC: H01R4/36
Filed: 2000-08-17
Abstract: This concerns a molded case circuit breaker having separable main contacts and an operating mechanism utilized to cause the separable main contacts to open and close. A trip unit is provided to actuate the operating mechanism in desirable circumstances. The circuit breaker has external terminals which are connectable with an external load and-an external power supply. A collar is used to interconnect the circuit breaker terminals with the load and power supply. The terminal collar in this case is non-symmetrical. The non-symmetrical collar provides two functions: the firs t function is that the path of electrical continently between adjacent collars  is enlarged for higher voltage applications because of the non-symmetrical nature of each collar; secondly, the circuit breaker case has a seat therein which has the same cross-section as the non-symmetrical collar, so that the collar can only be inserted therein in one cross-sectional orientation.< /SDOAB>

Title: Combination printing and quilting method and apparatus
Inventor: WHITE BURL
IPC: D06P5/30
Filed: 1999-04-27
Abstract: A quilting machine (10, 100, 200, 300) is provided having a quilting station (27, 127, 227) and a printing station (25, 125, 225) located upstream of the quilting station, with a conveyor (20) extending through each of the stations to convey a web (15) of quilting material through the machine.  At the printing station a top layer (15) is printed with a multi-colored design under the control of a programmed controller (35, 135, 235, 335), which may vary the design from section to section of the web so that individual or small quantities of panel sections of the web may be decorated with a different pattern. The conveyor preferably moves the quilting material relative to stationary heads (30), but the conveyor may alternatively stop at various stations and the printing or quilting heads moved relative to the stationary web on the conveyor. Pre-cise longitudinal position information is maintained of the location of the printed pattern. The conveyor then conveys the top patterned layer web through a drying station (26, 126, 226). After bringing the top layer web together with webs of filler (18) and backing material (17), the conveyor conveys the multi-layered web to the quilting station where a quilted pattern is caused by the controller to be sewn on the printed pattern bearing material in registration with the printed pattern.  Preferably, printing is applied before the quilting, but quilting before printing can be accomplished according to certain aspects of the invention. A cutoff station (28) separates the web panels bearing composite printed and quilted patterns under control of the programmed controller. For mattress cover manufacture, border panels can be quilted and printed in coordination with the top and bottom mattress panels, as part of the same webs of material from which they are then severed or in a separate synchronously controlled border making section (106).

Abstract: L'invention concerne un dispositif microfabriqué permettant de trier des cellules en fonction d'une caractéristique souhaitée. Des cellules marquées par un marqueur peuvent par exemple être triées en fonction de la présence ou de la quantité d'un marqueur sur ces cellules. Le dispositif de cette invention comprend une puce pourvue d'un substrat à l'intérieur duquel est microfabriquée au moins une unité d'analyse. Chaque unité d'analyse comprend un canal principal renfermant un canal d'admission d'échantillon, généralement placé à une extrémité, et une zone de détection située le long d'une partie de la longueur de ladite unité d'analyse. A proximité de cette zone de détection, et en aval de celle-ci, ledit canal principal renferme une zone de séparation ou un point de ramification menant à deux canaux de ramification. Cette unité d'analyse peut également comprendre autant de canaux d'admission, de points de détection, de points de ramification, et de canaux de ramification que nécessaire. Un courant renfermant des cellules traverse ladite zone de détection, de sorte qu'en moyenne, une cellule occupe cette zone de détection à un moment donné. Les cellules peuvent donc être triées dans un canal de ramification approprié, en fonction de la présence ou de la quantité d'un signal détectable comme un signal optique, et ce avec ou sans stimulation telle qu'une exposition à la lumière destinée à favoriser la fluorescence.

Title: A direct methanol fuel cell system with a device for the separation of the methanol and water mixture
Inventor: MATEJCEK LOTHAR
IPC: H01M8/1011
Filed: 2001-02-06
Abstract: A fuel cell system is described with a so-called direct methanol fuel cell (DMFC). To minimize the methanol crossover the concentration of the methanol/water mixture supplied to the anode of the fuel cell is made dependent on the magnitude of the electrical power takeoff. In order to be able to adapt the concentration of the methanol quickly in the case of a load change, it is proposed that a separating column be introduced into the anode cycle which reduces the concentration of the methanol. To achieve adapted increases in the concentration of methanol, both a concentrated methanol/water mixture from a secondary cycle and possibly additionally pure methanol from a tank are supplied. In the case of a reduction in the power demand only the secondary cycle needs to be blocked with the result that a lean mixture is available immediately.
