IPC: H01Q15/16
Filed: 1997-07-11
Abstract: A mesh material (10) for a spacecraft antenna (20) reflector is disclosed.  The mesh material has a base material (12) made from a dielectric fabric.   A conductive material (14), such as nickel, is applied to the dielectric mesh.   The type and thickness of the conductive material is adjusted to regulate the final conductivity of the reflective surface to a predefined range.

Patent CA-2213970-A1 (CA)
Inventor: HILLNER PAUL E
IPC: G01Q60/00
Filed: 1996-03-20
Abstract: A combined scanning probe and scanning energy microscope, in which the same scanning system is used for both the scanning probe and scanning energy images. A sample is translated substantially along a horizontal plane either between or below the probe (14) of a scanning probe microscope and the objective (12) of a scanning energy microscope. The probe (14) collects topographic or other information. The objective (12) focuses a fixed beam of energy to a small spot (16) on the sample, then collects energy from the same spot and transmits it to a detector (18). A vertical translator (22) connected to the probe (14) or sample support (10) provides the vertical motion necessary to maintain them in close proximity. The images produced by the two microscopes are in substantial direct registration with each other. The invention is exemplified by a combined atomic force and confocal laser scanning microscope with a translated sample.

Title: Short-range magnetic communication system
Inventor: PALERMO VINCENT
IPC: H04M1/60
Filed: 1996-05-17
Abstract: A system and method communicate signals between a portable unit and a communications system. The portable device communicates with a base unit using inductive coupling. The base unit is further connected to a wider communication system such as a telephone network. Multiple, orthogonally arranged transducers are used in the base unit to provide a more complete magnetic field and to prevent mutual inductance nulls which are otherwise present in a magnetic field. The use of short-range inductive coupling minimizes the power requirements and limits interference with other sources. The inductive coupling may also be used to recharge a battery in the portable device.

Abstract: Chimeric leptin which are proteins comprising leptin or a mutant or a variant thereof fused to a human immunogobulin domain. One favoured immunoglobulin domain is the human immunoglobulin Fc domain. The chimeric derivatives of leptin have, despite their large molecular size, good pharmacological activity combined with prolonged clearance rates. These derivatives of leptin are therefore indicated to be particularly useful for the treatment or prophylaxis of obesity or diseases and conditions associated with obesity such as atherosclerosis, hypertension and type II diabetes.

Inventor: RYALS JOHN ANDREW
IPC: C12Q1/68
Filed: 1997-07-18
Abstract: The nucleic acid sequence of the full-length, chemically inducible Arabidopsis PR-1 promoter has been discovered and is disclosed herein. Furthermore, cisacting regulatory elements in the Arabidopsis PR-1 promoter involved in chemical induction have been characterized using deletion and linker-scanning mutagenesis and in vivo footprinting. It has been discovered that at least a portion of the region of promoter between positions -698 and -621 (relative to the transcription start site of the PR-1 gene) is required for induction of gene expression by chemicals. Two 10-bp linker-scanning mutations centered at 640-bp and 610-bp upstream from the transcription start site abolish the inducibility of the promoter while another 10-bp mutation centered at -670 bp results in average induced expression levels 4-fold higher than the unmutated promoter. Additionally, inducible in vivo footprints are located at positions 629 and -628 and at position -604 on the coding strand and at position -641 on the non-coding strand. The use of chemically inducible Arabidopsis PR-1 promoter fragments to regulate gene expression in plants in the presence of inducing chemicals such as SA, INA, and BTH is disclosed, as well as the use of these elements for the isolation of transcriptional regulatory proteins involved in the promoter regulation and for the construction of inducible hybrid promoters.

Title: Clock signal cleaning circuit
Inventor: ARKAS NICHOLAS
IPC: H04L7/00
Filed: 1996-10-24
Abstract: A device which reduces fitter and narrows the frequency spectrum of a fitter-ridden clock signal includes a basic unit having a plurality of series connected delay elements outputs from each delay element are all connected to an AND/NAND gate. A front end of the device locates missing clock pulses and ensures regular clock pulses are relayed to the remainder of the device. A succeeding section including plural basic units hones the signal such that fitter elements are removed. By the output of this section time duty cycles are uneven, a positive edge triggered flip-flop is then used to obtain 50 % duty cycles at the expense of halving the clock signal's frequency. Optionally a frequency doubler can be employed to regain the clock signal's original frequency.

Title: Method and system for call disposition messaging
Inventor: DARLAND TIMOTHY
IPC: H04M11/00
Filed: 1996-11-07
Abstract: A method and system for creating and sending call disposition messages (300).  When a calling card is validated by the telephone network which issued the card (144), the card issuing network (144) can request a call disposition message (300). In response to validation of the call, a billing detail record (400) is generated and stored. When the call is completed, an operator service record (500) is generated. The operator service record (500) and its corresponding billing detail record (400) are matched with each other, then merged to form a merged operator services record (600). The merged operator services record (600) is processed to add pricing information. If the card issuing network (144) requested a call disposition message (300), the merged operator services record (600) is sent to a gateway (134) coupled to the card issuing network (144) where it is reformatted to create a call disposition message (300). The call disposition message (300) is then sent to the card issuing network (144).

Patent CA-2242155-A1 (CA)
Title: Ucr
Inventor: SCASE MARTIN ANDREW
IPC: B01J20/26
Filed: 1998-08-05
Abstract: A patent is sought for a new application, called UCR, that separates hydrocarbons from earth, sand, tarsand and oilsands. The current process for separating hydrocarbons from water, sand, oilsands, tarsands and earth is inefficient. The use of UCR, which is a combination of polyurethane and wollasontite, increases the efficiency in which the hydrocarbons can be recovered. The combination, which looks and acts like a sponge, attracts hydrocarbons. The hydrocarbons can be removed from the UCR by the use of pressure to squeeze the sponge. After the hydrocarbons are removed from the UCR, the UCR can be used again. The process works for hydrocarbons contained in earth, sand, oilsands and tarsands.
