Patent CA-2135255-A1 (CA)
Inventor: HEITMANN WILLIAM E
IPC: C21D7/13
Filed: 1994-11-07
Abstract: A billet of steel has a composition comprising small amounts of hardenability agents.  The billet is hot rolled into a continuous bar, in two hot rolling stages with an intervening cooling step employing a turbulent cooling liquid.  After the second hot rolling stage, the bar is gathered into a succession of closely overlapping loops and moved along a roller conveyor where the overlapping loops are cooled by air blowers, after which the bar is coiled.  The resulting hot rolled bar has a microstructure consisting essentially of bainite in fine-sized packets reflecting an average austenitic grain size, before the gathering and cooling steps, of 8-11 ASTM.  A threaded fastener in its final form can be produced from the hot rolled bar by a cold deforming operation without a heat treating operation before or after cold deforming.  The threaded fastener is undistorted and contains residual compressive stresses.

Patent CA-2143633-A1 (CA)
Title: Improved vector quantization
Inventor: NORMILE JAMES OLIVER
IPC: H04N19/94
Filed: 1993-08-31
Abstract: Improved method and apparatus for vector quantization (VQ) to build a codebook for the compression of data. The code-book (600) or "tree" is initialized by establishing N initial nodes (610) and creating the remainder of the codebook as a binary codebook (650). Children entries (670) are split upon determination of various attributes, such as maximum distortion, popula-tion, etc. Vectors obtained from the data are associated with the children nodes, and then representative children entries are recal-culated. This splitting/reassociation continues iteratively until a difference in error associated with the previous children and cur-rent children becomes less than a threshold. This splitting and reassociating process continues until the maximum number of terminal nodes is created in the tree, a total error or distortion threshold has been reached or some other criterion. The data may then be transmitted as a compressed bitstream comprising a codebook and indices referencing the codebook.
Patent CA-2147365-A1 (CA)
Title: Coin sorters
Inventor: STEELE LEONARD MARMADUKE
IPC: G07D3/12
Filed: 1993-11-04
Abstract: There are many occasions when it is required to sort a mixed lot of coins in-to their several denominations and when such a sort is carried out it is important that provision be made for distinguishing not only real coins of the required type one from another but also for differen-tiating both between these real coins and forgeries. The actual sorting - the physi-cal separation of each denomination from the others - can be accomplished in a variety of ways, and two of the most common involve one or other of what are known as disc sorters and ramp sorters; unfortunately, for either a disc or ramp sorter not merely to sort but also to dis-tinguish between proper and improper coins the equipment is inevitably ex-tremely bulky. The present invention seeks to overcome this size and weight problem, and indeed to provide a techni-cally rather more effective apparatus, by proposing a sorter which combines the facilities of both a disc and a ramp sorter. More specifically, the invention suggests a coin sorter (10) having both a disc (11) and a ramp (12), the disc being to gather the coins (14) from an associated feed hopper (15) and to deliver them to the ramp (12) via one or more detector station (16, 17) at which one or more of the coin's physical parameters is measured to determine whether the coin is proper or improper (and, if proper, very preferably what denomination it is), and the ramp (12) being in effect simply to separate the coins (14) into their various size-defined denominations and feed them to the appropriate delivery chutes (17).

Title: Procede et dispositif de regulation sur une plage admissible avec anticipation sur contextes utilisant la logique floue
Inventor: CHEBRE MERIAM
IPC: G05B13/02
Filed: 1995-07-10
Abstract: Le domaine de l'invention est celui de la régulation de grandeurs physiques dans les installations industrielles. Selon l'invention, on maintient entre deux valeurs limites la valeur d'une grandeur physique régulée soumise à des perturbations en modifiant une grandeur d'action. Ladite grandeur d'action doit avoir des amplitudes réduites pour stabiliser les flux en aval et doit évoluer de façon à anticiper les perturbations. Elle est déterminée en effectuant une inférence floue sur un jeu de règles de décision préalablement définies, à partir des valeurs de la grandeur physique régulée, d'une variable secondaire liée à la grandeur physique régulée et d'une variable de contexte obtenue à partir d'au moins une variable de détection ou d'une combinaison de variables de détection représentatives des grandeurs physiques à l'origine des perturbations de la grandeur physique régulée. L'invention trouve son application dans les industries de traitement du pétrole brut, les industries chimiques et papetières, ainsi que dans les installations et réseaux de distribution d'énergie, notamment de gaz.

Title: Casting steel strip
Inventor: ASSEFPOUR-DEZFULLY MASSOUD
IPC: B22D11/06
Filed: 1996-02-05
Abstract: A steel strip (12) is continuously cast from a pool (30) of molten metal that is supported on one or more chilled casting surfaces (22A). The casting surfaces (22A) are moved to produce a solidified strip (12) moving away from the casting pool (30) along a transit path (10).

Title: Method and equipment for producing foam bitumen
Inventor: SALMINEN NESTOR MIKAEL
IPC: B01F3/08
Filed: 1995-02-15
Abstract: The invention relates to a method and equipment for producing foam bitumen. Water is mixed to hot bitumen under a pressure which is lower than the prevailing absolute pressure, and after this the pressure is allowed to rise and the flow rate to drop. The mixing of water and bitumen occurs in a foaming reactor (17), which is connected via a pipeline (6, 8, 9, 10) to a spray bar (1), which also acts as a heat exchanger, and the changes in the flow caused by an inclination in the spray bar are compensated by means of pipes (6) and valves (7). The entire equipments is thermally insulated, and a part of it may be provided with electric heating to prevent the bitumen from solidifying. It is possible to circulate hot bitumen in the equipment by opening a valve (12), whereby the entire equipment is brought to an operating temperature.
Patent CA-2185258-A1 (CA)
Inventor: BARCLAY HUGH W
IPC: A61G5/12
Filed: 1996-09-11
Abstract: The invention is a footrest support structure for attachment to the frame of a wheelchair.  A footrest is carried on the end of a telescoping leg pivotally engaged to a wheelchair frame.   The telescoping leg automatically extends as it is elevated, by means of a folding link that engages the two parts of the leg.  The link is engaged as well by a lever lock that  permits  the  first  arm to  slide  freely  in  a  first direction but not in a second direction until the lock is actuated.   The first arm of the folding link is pivotally engaged to the upper leg at a first pivot point intermediate the ends of the first arm and the leg,  respectively,  for pivoting the arm in a generally vertical plane.  The second arm is pivotally engaged at its lower end to the lower leg at a second pivot point.  The distance between said first and second pivot points extends as the footrest support structure is elevated, thus causing the leg to elongate.

Abstract: An ostomy coupling has a first coupling member and a second coupling member. These are mutually interengageable and surround a region which includes a stomal orifice. A springy resilient ring encircles the two coupling members and has a handle member which can be manipulated to cause the ring to be deformed such that radially-inwardly extending tabs on the ring are shifted between respective first positions in which the ring is undeformed and the tabs lock the two coupling members together and respective second positions in which the ring is deformed in such a way as to shift the tabs radially outwardly to positions where they permit separation of the two coupling parts. The ring has a portion which joins the ends of two limbs of the ring, said portion being readily deformable and optionally sufficiently elastic such that the limb ends are pulled towards each other by the elasticity of said portion.
