Inventor: DUNCAN KELVIN WINSTON
IPC: C09K15/34
Filed: 1997-05-22
Abstract: A method for extraction and isolation of proanthocyanidins from botanical material. The method includes the steps of hot water extraction of the material after comminution using deoxygenated water, separation of the solids from the liquor, partitioning a liquor into a concentrated solution and waste streams by a method selected from ultra-filtration, reverse osmosis and a combination of the two in series, and drying the concentrated solution to a solid product. The hot water can be recycled. The residue results in a usable by-product and the tannins can be extracted from the tannin-rich stream. The most preferred botanical material is bark from Pinus radiata trees which are 15 years old, the bark most optionally coming from the upper portion of the tree.

Patent CA-2241948-A1 (CA)
Inventor: MAINE LESLIE
IPC: F16L13/14
Filed: 1997-11-03
Abstract: Two outer steel pipes (16 and 16A) are each lined by corrosion resistant lining pipes (18 and 18A) of compressible plastics material which stop short of the ends (20, 20A) of the outer pipes to leave an annular recess or counterbore (24 and 24A) at each of those ends. A tubular bridging-member (2) of ductile, plastically deformable, corrosion resistant material, for example brass or stainless steel has two tubular end portions (4 and 6) extending in opposite directions from an intermediate tubular portion (8) having an outer diameter greater than that of the end portions (4 and 6) and an inner diameter greater than that of the said end portions. The end portions (4 and 6) are encircled by ribs (12). Initially the outer diameter of the end portions (4, 6) is less than that of the inner diameter of the lining pipes (18, 18A). Thus each lined pipe (16, 16A) can be fitted over the respective end portions (4 and 6) with the intermediate portion (8) occupying the combined counterbore (24, 24A). A tool applied internally, radially expands the end portions (4 and 6) to compress the plastics lining pipes (18, 18A) against the outer pipes (16, 16A) by an amount in the range of 8 % to 30 % of the wall thickness of the lining pipes. Then adjacent ends (20, 20A) of the outer pipes are welded together at 28. The outer surface of the intermediate portion (8) can carry heat insulation material. The bridging-member (2) preserves the integrity of the internal corrosion resistance across the joint between the outer pipes.

Title: Protective cover for baby seats
Inventor: ROH WARREN E
IPC: A47C29/00
Filed: 1996-09-27
Abstract: The present invention describes a protective cover (10) that can be interchanged among a variety of baby seats. It includes a canopy (11) and a sealing element (22) that can interchangeably and flexibly seal around a variety of baby seats. It may also contain a removable hood (20) that may shield a portion of an insect-resistant mesh (15) so that a side mesh (15b) remains open for air and viewing of the occupant under the protective cover (10). Furthermore, the hood (20) may be attached at an approximate midpoint (26) of the canopy (11) to allow versatility in deploying the hood in a rearward direction and fastening the hood with attachment element (38). Likewise, the hood (20) may be folded in a forward direction and attached with attachment element (38) to a forward contour of a baby seat. The protective cover may include a protective foot shield (14) located under the hood (20) that may protect, for instance, feet of an occupant from a stinger or biting proboscis of a flying insect when the feet may touch the inside surfaces of the cover. Another feature of the present invention may include the ability of the present invention to be folded to a reduced state for easy storage and held in the reduced state by an integral restraining element which could be the hood (20). Another feature could be an inclement weather filtering configuration of mesh that could be located on the side to filter light, for instance, to a reduced level for the occupant's comfort.
Patent CA-2245747-A1 (CA)
Title: Telecommunications networks
Inventor: HOY MICHAEL DAVEY
IPC: H04Q3/00
Filed: 1997-02-27
Abstract: In a telecommunications network of the kind which handles non-time-critical calls (NTCC) in addition to normal telephony, a congestion indication is transmitted to NTCC transmitting platforms if volume and/or rate limit for a particular communications route or switch is exceeded. Transmitting platforms (9, 10, 11) establish a transmission rate based on a gaping rate (GR). On receipt of a congestion signal the platforms calculate an Inter call delay based on a random number multipled by a weighting factor determined from the current value of GR. This provides a period during which calls are not attempted after which GR is adjusted using a common ratio to provide a higher value of GR thus transmission rate (or the rate at which calls are offered) to the congestion route is less onerous. Consecutive call failures result in a rapid increase in the value of GR leading to longer ICDs (to allow the congested route/switch to recover) and a lower traffic loading on recovery.  Further, multiple transmitting platforms resume sending at different times due to randomisation of ICDs across platforms.

Title: Amplificateur a grand gain
Inventor: RATTAY BERNARD
IPC: H01L23/66
Filed: 1999-02-05
Abstract: Pour réaliser un amplificateur à grand gain dans une bande hyperfréquence, on propose de relier ensemble, des circuits d'amplification et de recouvrir le boîtier qui les contient, d'un couvercle (31). On ménage dans l'espace (33) situé entre le couvercle et les circuits d'amplification, à l'intérieur du boîtier, des guides d'onde (41-43) dont la fréquence de coupure est telle qu'elle ne laisse se propager aucun des modes pouvant régner aux fréquences de la bande utile. On montre qu'en formant ces guides d'onde dans cet espace, au lieu de le remplir d'absorbants, on obtient une bien meilleure isolation radioélectrique entre la sortie et l'entrée pour éviter des réinjections parasites. De ce fait on peut, dans un même boîtier, réaliser une amplification pouvant aller jusqu'à 90 dB alors qu'auparavant la limite à 45 dB par boîtier était infranchissable.
