Patent CA-2249539-A1 (CA)
Inventor: BROOKS KEITH
IPC: B65G53/24
Filed: 1998-10-05
Abstract: A vacuum particulate transfer apparatus is disclosed which employs a belt conveyor discharge rather than a conventional mechanical discharge auger. This handles products passing through the device more gently than prior art devices employing augers or other discharge apparatus and as such will have brought application in areas where particulate material was heretofore too fragile for handling by a vacuum transfer apparatus with a mechanical auger discharge.

Title: Control system for a plurality of groups of lifts with destination call control system
Inventor: KOSTKA MIROSLAV
IPC: B66B3/00
Filed: 1997-02-18
Abstract: The invention concerns a control system for a plurality of groups of lifts (G1 - G5), according to which system the passenger can input his destination at any destination call input device (TE) without having to know which group of lifts (G1 - G5) serves the desired storey. In this way, in large buildings in which, for structural reasons, the ranges of storeys served by individual groups of lifts (G1 - G5) are disposed adjacent one another in a confused manner, the passenger's search for the appropriate lift is facilitated. The multiple group control system always selects the most favourable lift from all the available lifts and, when the storey ranges served by a plurality of groups of lifts (G1 - G5) overlap, the selection is made from all the possible lifts.  If the passenger has to change lifts, the connecting lift is shown on a display.

Title: Grafts made from amniotic membrane; methods of separating, preserving, and using such grafts in surgeries
Inventor: TSENG SCHEFFER C G
IPC: A61K35/50
Filed: 1998-02-25
Abstract: A method for making, storing and using a surgical graft from human amniotic membrane; the resulting graft; and the storage solution.  The amniotic membrane is obtained from human placenta, from which the chorion has been separated. Sheets of the amniotic membrane are cut to size and mounted on filter paper. The cells of the amniotic membrane are killed, preferably while being frozen and thawed in the storage solution.

Title: Methods and compounds for curing diseases caused by mutations
Inventor: KMIEC ERIC B
IPC: A61K31/7088
Filed: 1997-05-01
Abstract: The invention concerns the use of duplex oligonucleotides having both 2'-deoxyribonucleotides and ribonucleotides, wherein there is base pairing between the two types of nucleotides. The sequence of the oligonucleotide is selected so that the 3' and 5' most regions of the oligonucleotides are homologous with (identical to) the sequence of a preselected target gene of a cell. The two regions of homology embrace a region that is heterologous with the target sequence. The introduction of the oligonucleotide into the nucleus of the cell causes the alteration of the target gene such that the sequence of the altered target gene is the sequence of the heterologous region.  Consequently, the oligonucleotides of the invention are termed chimeric mutation vectors (CMV). In one embodiment of the invention the target gene is a globin gene and the target cell is a hematopoietic stem cell. This embodiment can be used to correct certain hemoglobinopathies such as Sickle Cell Disease, .beta.-thalassemia and Gaucher Disease. The rate of correction of the globin gene is high enough so that no selection of the treated hematopoietic stem cells is required to obtain a therapeutically significant effect. In one embodiment the ribonucleotides of the CMV contain methylated 2'-O.

A horizontal sync component of the video signal is replaced in response to the horizontal sync signal sensed by the inductive pickups. A filter is arranged to filter out a band of frequencies centered about an integral multiple of a power line frequency. The capacitive pickup (12) has a capacitive pickup (12) plate and a capacitive shield plate which is located farther from the socket than the capacitive pickup plate. An axis of one of the two inductive pickups (14) is parallel to an axis of the CRT.

Filed: 1998-11-19
Abstract: A tray and method for packaging foil pans having outwardly-extending flange portions. The tray surrounds the outer bottom and side surfaces of the packaged foil pans, protecting the foil pans from damage. The tray includes an engagement portion with a lower surface and an inward protrusion, whereby the outwardly-extending flange portions of the packaged foil pans are securely held therebetween. An integral hang tab extends outwardly from the packaging tray to enable the tray with packaged foil pans to be hung from a display rack.  Trays with packaged foil pans may be nested together in either a horizontal orientation or a vertical orientation. Foil pans may be snap-locked into the tray by pressing the outwardly-extending flange portions against the inward protrusion, which flexes allowing the foil pans to pass by and then snaps back to retain the foil pans within the tray.

Filed: 1997-10-15
Abstract: A method of preparing a transgenic animal model with enhanced, accelerated pathology for Alzheimer's Disease (AD) and the transgenic animal made by the method are disclosed. The method includes producing an F1 generation by crossing a first and second transgenic parent each carrying a different expressible transgene for differing aspects of the same desired phenotype associated with AD pathology. The offsprings of the F1 generation are then screened and those which carry a transgene from each parental transgenic animal resulting in an enhanced pathology for Alzheimer's Disease are selected.

Title: Apparatus for tracking resonant frequency
Inventor: LONSDALE BRYAN
IPC: G01R23/07
Filed: 1997-11-13
Abstract: An apparatus for tracking the varying resonant frequency of an electrically resonant structure, characterised by: a variable frequency oscillator providing an excitation signal of a variable frequency encompassing the possible resonant frequency range of said resonant structure, a bidirectional RF transmission line connecting said variable frequency oscillator and said resonant structure, said transmission line incorporating a directional coupler which generates a directional coupler signal proportional to the reflected signal from said resonant structure, said directional coupler signal being conditioned by a processor to provide a feedback signal to the input of the variable frequency oscillator, such that the mean frequency of said excitation signal is caused to continuously track the varying resonant frequency of said resonant structure. Typically the tracking of said varying resonant frequency involves at least two functions, a first search function for initially searching the possible resonant frequency range of said resonant structure and, once resonance of said resonant structure is established, a second following function for following said variable resonant frequency as it varies as a function of time.

Title: Prosthetic foot providing plantar flexion and controlled dorsiflexion
Inventor: GABOURIE ROBERT MAURICE
IPC: A61F2/76
Filed: 1999-07-06
Abstract: The present invention relates to a prosthetic foot including an integral spring portion providing motion in the foot, particularly a unitary foot structure providing a selectable degree of plantar flexion and a stiff structure for toe off. The present invention has found that an integrally formed c-shaped spring portion having an anterior gap, joining a connection platform and the heel and forefoot portions can provide a controlled range of natural mobility in a prosthetic foot as an economical design. The c-shaped spring can deflect, angling the connection platform rearwardly to a partially opened position against the bias of the spring, and angling the connection platform forwardly until the stop abuts the top surface of the forefoot in a closed position. The stop is positioned a selected distance above the top surface to obtain the desired angle of dorsiflexion.  The plantar flexion against the bias of the spring is relatively stiff and provides a variable limit to the range of plantar flexion depending on the force exerted. In contrast, the deflection closing the c-shaped spring is relatively compliant but provides an angular range specifically defined by the position of the stop. In addition, the anterior gap also deflects to permit more limited inversion and eversion before the deflection is stabilized by contact between the stop and the top surface. Additional flexibility is obtained using an integral spring element having a substantially S-shape. The posterior facing c-shaped aperture in the S-shaped spring element provides additional deflection for plantar flexion.
