Title: Method of mass producing printed circuit antennas
Inventor: LAMPE ROSS W
IPC: H01Q1/38
Filed: 1996-10-16
Abstract: A method of mass producing printed circuit antennas is disclosed including the steps of providing a substrate of dielectric material having a first side and a second side, removing portions of the substrate to produce an array of interconnected segments of desired size, fabricating a main radiating element on the first side of each substrate segment, overmolding each substrate segment with a protective dielectric material, and separating each substrate segment from the dielectric substrate to form a plurality of individual printed circuit antennas. Preferably, each of the foregoing steps are able to be performed on each substrate segment substantially simultaneously. The method may also include the steps of freeing one end of the substrate segments, attaching an electrical connector to each substrate segment, and overmolding the electrical connector for each of the substrate segments prior to the separating step. Fabrication of additional radiating elements to the first or second side, or alternatively a reactive or parasitic element to the second side, may be undertaken so that the printed circuit antennas are capable of multi-band operation.
Patent CA-2235948-A1 (CA)
Title: Multicolor interference coating
Inventor: SHAW DAVID G
IPC: G02B1/10
Filed: 1996-03-19
Abstract: Several techniques  may be used for forming a colored interference filter coating on a substrate such as polyester film.  The interference filter has two metal reflective films, at least one of which is semi-transparent.  A layer of transparent acrylate polymer dielectric between the metal layers completes the interference filter, which may be sandwiched between protective layers.  The dielectric is formed by evaporating an acrylate monomer having a molecular weight in the range of from 150 to 600.  Preferably the acrylate monomer has molecular weight to acrylate group ratio in the range of from 150 to 400.  The acrylate condenses on the substrate and is polymerized in situ for forming a monolithic film with a sufficient thickness to produce an interference color.  In several embodiments different areas of the film have different thickness for producing different interference colors.  The thickness of the dielectric can be controlled by the amount of monomer condensed, by either controlling the temperature of the condensation surface or controlling the amount of monomer evaporated adjacent a predetermine area of the substrate.  Thickness may also be controlled by condensing a uniform layer of monomer and polymerizing the monomer to different degrees for varying the shrinkage of the film and hence the thickness of the film and color.

Title: Free-standing rotational rod-fed source
Inventor: HILL RUSSELL J
IPC: C23C14/30
Filed: 1998-05-11
Abstract: In a rotational rod-fed electron-beam evaporation source used with sublimating rod material, the ingot rod can be free-standing with respect to the crucible. This means that the side of the ingot rod near the tip of the rod does not contact a cooling crucible. In this way, the system can be operated in a defocused position of the electron beam, and the sweep of the electron beam can go over the edge of the ingot rod tip. Using these features, a substantially radial sweep of the tip of an ingot rod that sweeps over the edge can produce a substantially flat evaporation pattern on the ingot rod, producing a good utilization of the expensive ingot rod material.

Patent CA-2254433-A1 (CA)
Title: Liquid sample assay device
Inventor: MACARTNEY CHARLES TERENCE
IPC: B01L3/00
Filed: 1998-11-19
Abstract: An assay device for determining the presence of specific analytes in a liquid sample comprises a container for collecting the sample liquid and a removable cap for sealing the container. The cap includes one or more test strips, such as chromatography strips, supported thereon for visually displaying the results of the assay. A reservoir attached to the underside of the cap, collects, through a passageway, a predetermined volume of liquid from the container when it is inverted thereby submerging the reservoir in the sample liquid. The liquid collected in the reservoir is transferred to the chromatography strips by a wicking system. A valve member located in the reservoir automatically swells upon absorbing a portion of the liquid in the reservoir. Such swelling causes the valve member to close the passageway to form a hermetic seal between the liquid contained within the container and the outside thereby preventing such liquid from becoming contaminated and any leakage of the contained liquid.

Title: Removable embolus blood clot filter
Inventor: SIMON MORRIS
IPC: A61F2/01
Filed: 1997-07-16
Abstract: A blood clot filter (10, 36) which is collapsible toward a central longitudinal axis into a collapsed configuration for insertion into a blood vessel (22) and which is radially expandable outwardly from the longitudinal axis to an expanded configuration for contact with the inner wall of the blood vessel at two longitudinally spaced locations. A first plurality of spaced, elongate arms (18, 38), in the expanded configuration of the filter, curve outwardly away from the longitudinal axis toward the trailing end of the filter to form a first filter basket (14, 40). These arms (18, 38) prevent movement of the filter in a first longitudinal direction. A second plurality of spaced elongate legs (24, 46) angle outwardly away from the longitudinal axis toward the leading edge of the filter in the expanded configuration thereof. These second legs (24, 46) form a second filter basket (40) opening toward the leading end and prevent logitudinal movement of the filter in a second direction opposite to the first direction.

Inventor: HOON STEPHEN ROBERT
IPC: G01N27/72
Filed: 1997-08-11
Abstract: A method of and apparatus for torque magnetometry is disclosed. A specimen (2), the magnetic moment of which it is desired to determine, is disposed on a support means. A temporally varying, for example sinusoidal, magnetic field Bext is generated in the region of the specimen so that interaction between the magnetic moment M of the specimen and the magnetic field causes a torque to be exerted on the specimen. Consequently the specimen and/or the support are deflected, typically a vibratory motion is set up. Means are provided to measure the motion of the specimen and/or support due to the torque. When the magnitude and direction of the magnetic field are known, the magnetic moment of the specimen can be determined from the results of the motion measurement. The frequency of the magnetic field can be adjusted so that the specimen and/or the support resonate. The support is typically a single silicon crystal having two orthogonal modes of vibration which have different resonant frequencies. This can facilitate the independent determination of the three orthogonal components of the magnetic moment of the specimen.

IPC: D21H17/07
Filed: 1997-08-08
Abstract: Fibrous cellulose materials useful in the manufacture of soft, absorbent paper products such as paper towels, facial tissues, and toilet tissue are disclosed. The paper products contain a vegetable oil based quaternary ammonium chemical softening compound. Examples of preferred vegetable oil based quaternary ammonium chemical softening compounds include diester di(oleyl)dimethyl ammonium chloride (DEDODMAC) (i.e., di(octadec-z-9-eneoyloxyethyl)dimethyl) ammonium chloride) derived from canola oil and/or high oleic safflower oil.
