Patent CA-2242466-A1 (CA)
Title: Process and apparatus for manufacture of polymer composite products
Inventor: CHARLEBOIS RAYMOND
IPC: D06M15/263
Filed: 1997-01-10
Abstract: Polymer composite products, including products made of polymer concrete, reinforced polymer concrete and reinforced plastics, such as bulk molding compound, sheet molding compound, mineral molding compound and advanced molding compound systems, are produced by the simultaneous application of vibration, heat and pressure to a mixture of filler and polymeric binder. The simultaneous application of vibration, heat and pressure provides a protective layer of polymerized binder that protects the surfaces of the mold and provides products that are substantially free of curling, cracking or voids.  The process and apparatus of the present invention substantially reduce the time required to cure polymer composite products.

Patent CA-2249152-A1 (CA)
Title: Apparatus for and method of managing bandwidth for a packet-based connection
Inventor: CHAPMAN ALAN STANLEY JOHN
IPC: H04L47/267
Filed: 1998-09-30
Abstract: Flow control of packet based traffic by window is known. Novel modification is described which causes the flow control mechanism to reduce sending rate to some configured number rather than just reducing it by a fixed amount such as one half. The description also shows how the flow control mechanism can be constrained to a maximum rate. The configured numbers will assure that the connection can always run at a minimum rate but not more than a maximum rate. If the guaranteed minimum bandwidth is known and the round trip time between the end points is known or has been calculated, then the sender node needs only reduce its window to that which corresponds to a sending rate equal to that configured number. In this way the protocol will still probe for extra, opportunistic bandwidth but will be able to maintain the minimum rate. In a similar way a window that corresponds to the maximum rate can be calculated and used to constrain the maximum rate of sending.

Patent CA-2252057-A1 (CA)
Title: Method for determining pressure
Inventor: PAL ALEXANDER
IPC: G01L11/02
Filed: 1997-04-01
Abstract: A method of determining pressure requires that a three-dimensional surface of an object (14) be covered with a pressure sensitive coating. Next a raw first image (74) is acquired while the object (14) is not under test and a raw second image (74) is acquired while the object is under test. The raw first image (74) and the raw second image (74) are adjusted for a dark image (76) to form an adjusted first image and an adjusted second image. The adjusted first image and the adjusted second image are mapped (78) from a two-dimensional representation onto a three-dimensional model, to form a first model and a second model. A ratio model is formed (80) by taking the ratio of the intensity of the first model and the second model. Finally, a pressure is determined (84) for every surface that forms the three-dimensional model.

Patent CA-2272151-A1 (CA)
Inventor: KHADEM FEREIDOUN FEDOR
IPC: A22C7/00
Filed: 1999-05-25
Abstract: Hamburger patties that are prepared through mass-production must be well cooked but not burned and should also remain juicy. To ensure that the Hamburger meat is well cooked, the amount of heat should be adjusted to the thickness of the patties. Another way to cook the patties properly is to adjust the thickness of the patties to the amount of heat available. The new invention is based on matching the thickness of the meat patties to the amount of heat available from cooking facilities. The equipment for this purpose consists of a surrounding-ring of an appropriate diameter, thickness and height, a bottom and a top plate are prepared each with a pressing-disc, and several matching-discs. The ring is used to keep diameters of the patties constant. In the wall of the ring is a hole prepared to allow the surplus meet be squeezed out.  The pressing discs press the meat and the matching-discs are changeable to change the thickness of the patties. This discs are placed into the ring on top of the bottom pressing-disc. The matching-discs together with the bottom pressing-disc are covered with a thin celluloid film or a plastic foil to avoid the meat from sticking to the mould. A certain amount of meat is put into the ring and pressed down with the top pressing-disc. The top pressing-disc is also covered with a plastic foil. While pressing the meat, the surplus meat is then squeezed out of the mould through the ring hole and matches the patty thickness as required. The top plate with pressing-disc and the surrounding-ring are then removed to take the meat patty out of the mould. If the test patty is not cooked properly, the distance-disc should be changed accordingly until the meat is properly cooked.  Once the thickness of the test patty is matched to the regulated heat of the cooking facility, the subsequent patties can then be made thereafter at any time with the same setting of the equipment.
