Patent CA-2224215-A1 (CA)
Title: Filter
Inventor: GALLAGHER PAUL MARTIN
IPC: B01D65/00
Filed: 1996-06-10
Abstract: A filter comprising an array of bundles of open-ended filter tubes each housed within and extending along the length of a support tube. Filter tube seals are arranged at each end of each support tube such that the filter tubes extend therethrough, the seals preventing axial flow through the ends of the support tubes except through the filter tubes. A tubular housing receives each support tube, at least two conduits communicating with openings in each housing. Axially spaced annular seals located between each support tube and the associated housing divide the space defined between the support tube and housing into axially spaced regions which communicate with respective conduits. Openings in the support tubes communicate with respective conduits through the spaces between the housing and support tubes. One of the openings in each support tube communicates with the open ends of the filter tubes, and another communicates with the space within the support tube around the filter tubes and between the filter tube seals. The housings have removable covers which when removed leave apertures axially aligned with the support tubes to enable the insertion and removal of the support tubes in the axial direction. The covers may be transparent to enable visual inspection of the flow within the support tubes, and the housings may incorporate slidable plugs to enable the selective isolation of individual tube bundles.

Patent CA-2231554-A1 (CA)
Inventor: PORTEGIES HANS
IPC: B23P19/04
Filed: 1998-04-02
Abstract: An in-line linear/rotary drive mechanism for a voice coil actuator includes an electro-magnetic drive motor having a rotatable drive shaft. Specifically, both the drive motor and its rotatable shaft are slidably mounted for translational movement on the housing of the actuator. An actuator probe is also slidably mounted on the actuator housing. Importantly, a bearing unit constrains the actuator probe to translational movement along a predetermined axis on the actuator housing. Further, a rotary-servo coupling selectively connects the rotatable drive shaft of the electro-magnetic drive motor with the actuator probe. Within this combination, the actuator probe moves in direct translation with the drive motor along the predetermined axis. Also, within this combination the actuator probe moves in rotation about the predetermined axis in response to the rotatable drive shaft.

Inventor: SORENSON JAMES L
IPC: A61K9/70
Filed: 1996-09-13
Abstract: L'invention concerne une forme médicamenteuse, capable de traverser les ongles et de faire passer un médicament à travers les ongles, les griffes, les sabots ou d'autres tissus similaires, formés par durcissement du derme. La forme médicamenteuse capable de traverser les ongles comprend une enzyme protéolytique qui facilite la perméation de la substance à travers l'ongle dur ou le tissu kératineux. L'invention concerne également une forme médicamenteuse capable de traiter une maladie spécifique. La forme médicamenteuse capable de traverser l'ongle est particulièrement utile pour traiter l'onychomycose des ongles des doigts ou des orteils, ce qui évite d'avoir à prendre des mesures thérapeutiques plus draconiennes, comme l'excision de l'ongle.

Patent CA-2240646-A1 (CA)
Inventor: VINEGAR HAROLD J
IPC: E21B36/02
Filed: 1996-12-17
Abstract: A flameless combustor eliminates the flamme as a radiant heat source, which results in a more even temperature distribution throughout the length of the burner. Flameless combustion is accomplished by preheating the fuel and the combustion air to a temperature above the autoignition temperature of the mixture. The present invention lowers the autoignition temperature by placing a catalytic surface within the desired combustion chamber. Temperatures are maintained above the catalyzed autoignition temperature but less than the noncatalyzed autoignition temperatures for noncatalyzed reaction. Thus, the amount and location of reaction can be controlled by varying the amount and distribution of catalyst within the burner. Removing heat from the combustion chamber in amounts that correspond to the oxidation of fuel within different segments of the combustion chamber can result in low temperatures and relatively even distribution of heat from the burner.

IPC: F25B41/06
Filed: 1999-04-08
Abstract: A refrigerant system having individual thermal expansion valves for controlling refrigerant flow from a common compressor and condenser to separate remotely located evaporators such as for vehicle front and rear seat passenger comfort. One of the remote thermal expansion valves has a thermoelectric cooler in heat conducting relationship with the fluid filled power capsule of the valve. Upon energization of the thermoelectric cooler the sensed temperature of the refrigerant returning through the valve from the evaporator to the compressor is altered to cause the valve to reduce refrigerant flow to the evaporator to compensate for reduced refrigerant supply pressure due to flow through the other thermal expansion valve.
