Patent CA-2307279-A1 (CA)
Title: Optical diagnostic tool
Inventor: KHOURY ELIE
IPC: A61B3/11
Filed: 2000-05-09
Abstract: An optical diagnostic tool for allowing an observer to obtain optical information regarding various characteristics of the eyes of an intended patient. The tool includes an enclosure defining a peripheral wall, a patient end wall and an observer end wall. An optical dividing wall is positioned within the enclosure. The optical dividing wall divides the enclosure into a first and a second optical chamber, allowing for the creation of distinct lighting pattern in the first and second optical chambers. A first and a second patient eye aperture both extend through the patient end wall. The first and second patient eye apertures individually establish visual communication respectively with the first and second optical chambers. An observer visual access structure allows the observer to obtain selective optical access to either one or both of the first and second optical chambers and to either one or both of the corresponding first and second patient eye apertures. A selective light emitting structure mounted within the enclosure allows for the creation of the predetermined distinct lighting patterns in the first and second optical chambers.

Title: Single coil dual path dehumidification system
Inventor: MIERINS RAYMOND A
IPC: F24F3/14
Filed: 2000-08-25
Abstract: A dual path single coil dehumidification system is provided. The system includes a housing that is mounted onto the top of a building that is to be dehumidified. The system draws in outside air which is circulated along its own dedicated path. A cooling coil is disposed in the dedicated outside air path. The outside air therefore passes over the cooling coil and is dehumidified prior to being mixed with any other air. The system also draws in return air from the interior of the building. The system is arranged so that the return air is drawn over refrigeration units that are located in the building to cool the return air. The cooled return air is then drawn into the housing where it is mixed with the outside air only after the outside air passes over the cooling coil. The mixed dehumidified outside air and the cooled return air form a supply air stream that is delivered to the interior of the building.

Title: A method of producing a detector belonging to a gas sensor, and a detector produced in accordance with the method
Inventor: MARTIN HANS GORAN EVALD
IPC: G01N21/35
Filed: 1999-02-04
Abstract: The present invention relates to a method of producing a gas sensor co-acting detector intended for the detection of electromagnetic waves, such as infrared light rays, that pass through a gas cell. The gas cell (2) includes a cavity (21), which functions to enclose a gas volume (G) for measuring of evaluating purposes. The surface or parts of the surface forming walls within the gas cell or the cavity is/are coated with one or more different metal layers (M1, M2) with the intention of providing a highly reflective surface for reflection of said electromagnetic waves. The detector (3) is comprised of a thermal element and is formed on a base structure (31). That part of the base structure that shall form said detector is comprised of one or more topographically structured surface regions. At least said surface region or surface regions is/are coated with a first and a second electrically conductive metal layer (M1 and M2 respectively) which are intended to form said thermocouple. The first metal layer (M1) is applied at a first angle other than 90~, and the second metal layer (M2) is applied at a second angle which is also other than 90~ and which differs from the first angle. The topographical structure and/or configuration including the thus coated electrically conductive layers provides the function of one or more thermocouples, by virtue of the first and the second metal layers (M1, M2) overlapping each other within discrete detector-associated surface parts.

Title: Nonionic surfactant granules by prilling
Inventor: RAEHSE WILFRIED
IPC: C11D17/00
Filed: 2000-12-11
Abstract: The problem addressed by the invention was to provide granules which would have a high content of liquid nonionic surfactants, more particularly above 20% by weight, but which would have little need for a water-insoluble carrier material and would be eminently suitable for incorporation in detergents. It has been found that granules of nonionic surfactants liquid at room temperature which contain a solidified polymer melt as carrier material and less than 10% by weight of inorganic carrier satisfy these requirements.

Title: Ring binder having actuating lever with cushion member
Inventor: TO CHUN YUEN
IPC: B42F13/26
Filed: 2001-01-19
Abstract: A ring binder includes a substantially rigid curved upper plate supporting a pair of hinged leaves. A plurality of ring members are secured to the hinged leaves for engaging corresponding holes in sheets of material retained by the ring binder. An actuating lever is located at each end of the curved upper plate for actuating the hinged leaves to open and close the ring members. Each actuating lever includes a tab having a pair of spaced-apart apertures therein. A cushion member is located on the tab, which includes an inner cushion part and an outer cushion part which are interconnected by a pair of connecting parts which extend through the spaced-apart apertures in the tab to securely attach the cushion member to the tab. The cushion member is engaged by the fingers of a user to pivot the actuating lever in order to move the ring members between the open position and the closed position. The cushion member is a soft pad of resilient material such as rubber or soft plastic. The cushion member provides improved tactile characteristics to the actuating lever, making the actuating lever comfortable to use. The cushion member also minimizes the feedback of undesirable shock forces produced by the snap action of the rings when opening and closing the rings.
