Title: Multiple band radio
Inventor: WHEATLEY CHARLES E III
IPC: H04B1/40
Filed: 1995-09-27
Abstract: The dual band code division multiple access radio of the present invention operates on multiple frequencies simultaneously on either transmit or receive. The transmit path operates by splitting the transmit intermediate frequency (IF) path (103) and mixing the IF to two different transmit frequencies using two frequency synthesizers (140 and 145).  The receive path (104) has two RF channels (116 and 117) that are mixed with the frequencies generated by the synthesizers (140 and 145) and summed into one IF strip. Thus the radio of the present invention can perform a soft hand-off between frequencies while communicating with both base stations simultaneously. Additional mixing paths and synthesizers can be added if it is desired to communicate with more than two base stations simultaneously.

Title: A filter arrangement for a collection bag for body exudates
Inventor: OLSEN HANS
IPC: A61F5/441
Filed: 1995-09-28
Abstract: A filter arrangement for a bag (1), in particular an ostomy bag with a vent (5), comprising a filter holder (7) fastened to the wall of the bag at the vent and having a through hole forming a passage from the interior of the bag to the surroundings, and a replaceable filter insert (8) designed for positioning in said hole. For position fixing of the filter insert in a use position, the filter holder has both means (13) for engagement with corresponding means (14) on the filter insert where the engagement means are designed such that upon positioning in the use position, the filter insert is prevented from being withdrawn from the filter holder, and within said engagement means has an elastically resilient clamping member (15) which in use position forms a sealing around the filter insert, but allows that this is pushed from the outside through the hole of the filter holder into the bag.  The engagement means may be formed as an inwardly facing shoulder portion (13) in the filter holder (7) and a corresponding outwardly facing shoulder portion (14) on the filter insert (8). The filter insert has within said shoulder portion an internal conical end part with inwardly convergent cross section, and the elastically resilient clamping member (15) of the holder forms a sealing lip around said end part of the insert.

Title: Moisture resistant frozen food packaging using an over-print varnish
Inventor: CLAYTOR ROBINSON CAMDEN PERKIN
IPC: B41M7/02
Filed: 1997-05-30
Abstract: This invention relates to moisture resistant frozen food packaging using highly-sized paperboard and press applied moisture resistant over-print varnishes.   Such structures of this type,  generally,  employ a moisture-resistant coating which is placed between the food product and the paperboard in order to provide a barrier for the food from the board and also to prevent the paperboard from absorbing moisture.  Also, edge-wick moisture absorption is minimized by the use of the highly-sized sheet.

Title: Elimination of cyanides in the dehalogenation of halofluorocarbons
Inventor: ABEL MARC W
IPC: C09K5/04
Filed: 1995-12-19
Abstract: Ozone depleting fluorocarbon compounds (18) are dehalogenated through more economic reduction reaction with solvated electrons formed from lower equivalents of reactive metals (14) than previously used by reacting the partial reduction products with nitrogen-containing bases, such as ammonia (12) or alternatively, without any reactive metal by reacting with the base alone. Mixtures of fluorocarbon refrigerants including difficult-to-separate azeotropes of dichlorodifluoromethane contaminated with clorodifluoromethane are reclaimed by treating only with weak non-aqueous nitrogen-containing bases to provide essentially chemically pure dichlorodifluoromethanerefrigerant suitable for recycling/reuse. Hazardous cyanides which may develop are converted to relatively benign products during the process by introducing a base (22) to convert volatile cyanides to more stable salts which in turn are converted to useful compounds of lesser toxicity.

Patent CA-2218457-A1 (CA)
Inventor: CALLE GILLES MICHEL GEORGES LO
IPC: B21D26/02
Filed: 1997-10-10
Abstract: The procedure consists of assembling the primary components (11) and placing them in a furnace, subjecting to pre-baking and eliminating the binding agent of the anti-diffusion product. Then, without moving the components, the interior of the blade assembly (14) is subjected to a vacuum and a simultaneous increase in temperature to produce a permanent plastic deformation of the components. The interior of the blade assembly, made from a titanium alloy, is kept under the vacuum while an isostatic pressure is applied to the exterior, with the pressure and temperature conditions maintained to ensure a compaction of the anti-diffusion product and a pre-welding of the non-coated zones of the diffusion barrier. The assembly is subsequently inflated by gas pressure and superplastically moulded before subjecting to final machining.

Title: Multi-spectral segmentation for image analysis
Inventor: RAZ RYAN S
IPC: G01N21/27
Filed: 1996-07-18
Abstract: A method for segmenting spectrally-resolved images. The first step comprises acquisition of three images of the same micrographic scene. Each image is obtained using a different narrow band-pass optical filter which has the effect of selecting a narrow band of optical wavelengths associated with distinguishing absorption peaks in the stain spectra. The choice of optical wavelength bands is guided by the degree of separation afforded by these peaks when used to distinguish the different types of cellular material on the slide surface. By combining these images in a particular fashion, it is possible to achieve a high degree of success in separating the cervical cell from the background and the nuclei from the cytoplasm.

Filed: 1996-07-24
Abstract: A classifier (500) measures robustness responsive to object presentation effects and decision boundary effects. A cytological image analysis computer (562) obtains objects of interest and classifies them responsive to a decision tree classifier (Figure 8). The robustness of classification is calculated dynamically as objects are classified responsive to a segmentation robustness (38) and a classification decisiveness measure (42). The results of the decisiveness measure and the segmentation robustness data are combined to provide enhanced overall classification reliability (48).
