Patent CA-2286475-A1 (CA)
Title: Absorbent structure having improved fluid surge management and product incorporating same
Inventor: SHERSHIN ANN MARIE
IPC: A61F13/15
Filed: 1990-04-09
Abstract: An absorbent article includes a retention portion for storing absorbed liquids, and a distinctive surge management portion. The surge management portion, which has a selected basis weight, is constructed to rapidly uptake and temporarily hold at least three (3) successive surges of liquid directed into the target zone of the article and then release each of the surges to the retention portion.      The retention portion desorbs each input of liquid from the surge management portion and stores the liquid. Particular functional and structural parameters can further characterize the surge management portion of the absorbent article.

Title: Method and system for accessing electronic resources via machine-readable data on intelligent documents
Inventor: DURST ROBERT T JR
IPC: H04L9/32
Filed: 1998-05-09
Abstract: A method of accessing electronic resources via machine readable data embedded on a document which comprises compressing input data with a transmitter adapted to save a first bandwidth using a compression method adapted to minimize utilization of bandwidth by the compressed input data while retaining substantially all information content of the input data and appending a compression flag to the compressed input data indicative of the compression method enabling a receiver to decompress the compressed input data. The compression step further comprises utilizing a compression dictionary adapted to map the elements and strings of the input data to minimized representations having redundancies deleted. The compression dictionary may be appended to the compressed input data (as cleartext or cyphertext) under circumstances where a bandwidth occupied by the appended compression dictionary is less than the bandwidth saved by the step of compressing the input data. The compression dictionary may also be selected by the receiver independently from the transmitter independently indexes, pointer registration, application restricted subsets or customized according to the input data content. Also the input data may be encrypted, and an encryption flag appended which is indicative of the encryption method enabling decryption via public or private key cryptosystems as well as utilizing various authentication techniques such as digital signatures to ensure that the document was created by a licensed user.

IPC: B60R13/04
Filed: 1999-12-02
Abstract: A removable, portable, foldable protector for side doors of parked vehicles. A plurality of panels, preferably but not necessarily of plastic are connected, side-by-side, by hinges which will allow the panels to fold on each other when folded and to allow the panels to unfold into a locked position and then mounted to the inner and outer edge of each front door by means of a combination plastic-rubber clamp or any other suitable means. Each panel forming the protector further has a foam rubber material attached to the side of the panel that will face the vehicle door.  Thus, when the device is installed on the vehicle with the vehicle parked in a parking lot, the opening of an automobile door adjacent thereto will not mar the automobile finish.

Inventor: HEITKAEMPER PETER
IPC: C07C263/10
Filed: 1999-12-17
Abstract: Durene diisocyanate is prepared by reacting durene with nitric acid in sulfuric acid, catalytic hydrogenation of the dinitrodurene that is formed, and phosgenation of the resultant durene diamine in a conventional manner. The intermediate products dinitrodurene and durene diamine do not have to be worked up in a complicated manner as solid products, but can be worked up in dissolved form. The intermediate products dinitrodurene and durene diamine do not have to be isolated and purified in a complicated manner, but can be processed directly after preparation. Another advantage of this process is that only a single organic solvent need be used for the overall preparation process. Separation and re-use of spent acid in the conversion of durene with nitric acid also renders the process of the present invention significantly less environmentally harmful than the known processes of the prior art.

IPC: H04M1/663
Filed: 1998-03-12
Abstract: On décrit un appareil de téléphone qui permet à un central de filtrer les appels sur la base de messages contenant des données de message, puis à transmettre ces messages préalablement à la transmission d'une première rafale d'appel. L'appareil inclut un récepteur de messages, un décodeur, une sonnerie d'appel et une commande de la sonnerie d'appel. Le récepteur de messages communique avec la ligne de central et peut être mis en oeuvre pour recevoir des messages pendant que le téléphone est en position de repos. Le décodeur décode le message pour en extraire les données de message. La sonnerie d'appel peut être mise en oeuvre pour émettre une alarme audible lorsqu'un appel téléphonique est reçu et, quand une certaine condition préétablie est remplie par les données de message, ladite commande empêche la sonnerie d'appel de sonner en réponse à la première rafale d'appel.

Patent CA-2310034-A1 (CA)
Title: Compression moulding method
Inventor: KELLY PAUL ANDREW
IPC: B29C43/32
Filed: 1998-11-10
Abstract: A method of compression moulding an article from rubber moulding material incorporating hollow inserts (10, 35) avoids damage to the inserts. Where compression moulding takes place in an enclosed mould at an elevated pressure, the pressure can distort and damage the hollow inserts (10, 35) especially if they are of plastics. In order to avoid such distortion and damage, the method compresses during moulding creating a pressure in a cavity (20, 36) of the insert (10, 35) which substantially balances the pressure exerted on the exterior of the insert by the rubber moulding material in the mould. The pressure in the cavity (20, 36) is preferably produced by introducing some rubber moulding material into the cavity (20, 36) of the insert (20, 35). This material becomes pressurised during moulding and supports the interior of the insert (10, 35).

Patent CA-2323857-A1 (CA)
Inventor: MCNEELY MICHAEL D
IPC: G05D16/16
Filed: 2000-10-20
Abstract: A pilot operator and a relief valve are provided in the same housing. The pilot--operating mechanism is contained partially within the main closure element of the valve and partially within the valve cap. Inlet pressure to the valve is communicated to the pilot via an access passage extending through the main closure element. In response to high-pressure flow from the inlet, a pilot piston moves a spacer rod through the passage and into engagement with a spring-loaded vent closure. The piston-induced movement of the rod opens the vent to relieve the pressure behind the main closure element, which in turn permits the main closure element to open and relieve the inlet pressure through the valve outlet. Opening of the main closure element terminates flow through the access passage. When the inlet pressure is sufficiently reduced, the pilot piston is unseated by the spring force re-opening the access passage to allow the pressure behind the main closure element to increase and close the main closure element. A back-flow- prevention assembly carried in the main closure element prevents reverse flow of fluids from the outlet to the inlet when the outlet pressure exceeds the inlet pressure.

Abstract: A l'étape S101, l'utilisateur entre deux courbes pour le début et la fin et un point correspondant à des références pour chaque courbe. A l'étape S102, les points correspondant à des références sont tracés pour les images consécutives le long de l'axe de temps. Il en résulte que les positions des points correspondant à des références sont déterminées à des stades intermédiaires. A l'étape S103, l'interpolation de formes est effectuée. A l'étape S104, la forme interpolée produite à l'étape S103 est déformée en fonction des points correspondant à des références déterminés par le tracé à l'étape S102. Par conséquent, les points correspondants sur les contours sont tracés de manière précise, même si le contour se déplace de manière non linéaire, ce qui entraîne la formation d'un contour plus précis.
