Title: Classeur a anneaux pliable economisant de l'espace
Inventor: HUDSPITH SYDNEY
IPC: B42F13/16
Filed: 1997-05-14
Abstract: Cette invention se rapporte à un classeur à anneaux (10) économisant de l'espace, qui se trouve en position pliée lorsqu'il n'est pas utilisé, par exemple lorsqu'il est emballé, expédié ou stocké ou lorsqu'il occupe un espace de rangement, et en position droite, lorsqu'il est utilisé pour le classement de feuilles de papier. L'épaisseur de ce classeur à anneaux (10) est considérablement moindre lorsqu'il est position pliée que lorsqu'il est en position droite. Ce classeur à anneaux (10) comprend une partie couverture (14, 16, 18) et une partie reliure (12) fixée à la partie couverture (14, 16, 18). La partie reliure comporte plusieurs anneaux (26) fixés rotatifs à une unité à bascule (22, 24). Les anneaux (26) peuvent pivoter pour passer d'une position pliée, dans laquelle les anneaux (26) définissent un angle aigu par rapport à l'unité à bascule (22, 24), à une position droite dans laquelle les anneaux (26) sont essentiellement perpendiculaires à l'unité à bascule (22, 24).

Abstract: Signal processing to remove unwanted signal components of non-linear elements such as RF amplifiers in broadband wireless communications systems that exhibit unwanted intermodulation products. An information signal is processed to form a processed output signal, Vod. A signal preprocessor includes a base modulator for modulating the information signal to form base modulated signals, a band modulator for modulating the base modulated signals to form an input signal, Vi, a distortion processor for providing a predistortion signal Vpd having selected predistortion terms of the Taylor series form ¢k1(Vi)1, k2(Vi)2, k3(Vi)3,...!, and a broadband processor for combining the input signal Vi and the predistortion signal Vpd to form a predistorted signal Vid with the selected predistortion terms of the Taylor series form ¢k1(Vi)1, k2(Vi)2, k3(Vi)3,...! having reduced amplitude. A non-linear element having a non-linear transfer function for process the predistorted signal Vid to form the output signal with the selected predistortion terms of the Taylor series form ¢k1(Vi)1, k2(Vi)2, k3(Vi)3,...! having reduced amplitude. Amplifiers achieve substantial improvements in efficiency, an increase of 40-80% of usable power, due to the reduction of intermodulation products. In particular, the third order products are reduced.

Abstract: The present invention relates to detergent compositions, including dishwashing, hard surface cleaning and laundry compositions containing a pectinesterase substantially free of other pectic enzymes and especially an alkaline pectinesterase for significant overall cleaning performance and stain/soil removal benefits and in particular removal of body, plant, dried-on fruit and vegetables juice soils/stains.
Patent CA-2263428-A1 (CA)
Inventor: GALLANT DENNIS
IPC: A61B19/00
Filed: 1997-08-21
Abstract: A patient/nurse call system (10) for a hospital includes patient stations (18) capable of generating hospital calls and a remote master station (32) which prioritizes and stores the calls. Hall units (28) outside patient rooms (14) identify the rooms (14) from which the calls originate and the type of call.  Each patient station (18) allows selective retrieval and display of unanswered calls, and the system (10) further permits audio interconnection between any two of the stations (18, 32). Nurse-worn badges (26) transmit pulse-coded infrared signals which are received by receivers (121) at the patient stations (18) and in response, the system (10) generates identity and location signals which are stored at the master station (32). The nurse location and identity information may also be retrieved and displayed at any patient station (18).  Receipt of a nurse's (11) infrared signal at a room station (18) automatically cancels a patient call originating from the room (14) and display thereof by the respective hall unit (28), while actuating a display (122) to indicate nurse (11) presence. By using the nurse call button (22), the patient can establish telephonic communications between the patient station (18) and a wireless telephone (64) being carried by a remotely located nurse.

Patent CA-2269752-A1 (CA)
Inventor: ROBINSON SIMON PIERS
IPC: C12N9/02
Filed: 1997-01-24
Abstract: The present invention relates to the isolation of genes encoding polyphenol oxidase (PPO) from plants. In a first aspect of the present invention there is provided a method for preparing nucleic acid encoding PPO, fragments and derivatives thereof, which method includes providing a sample of plant tissue, a first primer in sense orientation having a sequence corresponding to a conserved region of a PPO gene, a second primer in antisense orientation having a sequence corresponding to a conserved region of a PPO gene; isolating genomic DNA from said plant tissue; and amplifying the genomic DNA using the first and second primers. Surprisingly, the applicant has found that PPO genes in plants lack introns and, therefore, fragments of PPO genes may be amplified directly from genomic DNA of a range of plants. The lack of introns means that the size of the fragments can be predicted and bands of the appropriate size can be selected for cloning.

Title: Extrusion die system with removable insert
Inventor: COOK MICHAEL CHARLES
IPC: B29C48/05
Filed: 1999-05-04
Abstract: A die system for the extrusion of polymer permits external cleaning and maintenance without shutting down the operation. Removable die inserts are located on one or both sides of the die opening section through which polymer is extruded. The inserts are spaced from the die opening section, by a very small distance, so as to avoid interfering with the opening section. When molten polymer accumulates and burns in areas surrounding the die opening section, the inserts can be removed and replaced without interrupting the extrusion of polymer.

Title: Programmable crystal oscillator
Inventor: FALLISGAARD JOHN W
IPC: H03B1/00
Filed: 1998-02-03
Abstract: A programmable crystal oscillator is provided having a memory for storing frequency-defining parameters. Typically, one of these parameters is used to program an adjustable capacitive load circuit coupled to a crystal to thereby adjust the crystal source frequency. Additional parameters are used to program the output frequency of a phase locked loop circuit coupled to receive the adjusted source frequency. A further parameter can also be used to divide the output frequency of the phase locked loop circuit to supply a specified output frequency. The oscillators can be manufactured as generic programmable crystal oscillators without regard for output frequency and then quickly programmed to produce customer-specified output frequencies with a high degree of accuracy.

Patent CA-2288340-A1 (CA)
Inventor: MOJGANI FOAD
IPC: H04M3/48
Filed: 1999-11-02
Abstract: A method is disclosed of conveying information from a caller to an intended recipient along a telecommunications network where if the call cannot be placed initially because the recipient at a directory number (DN) is busy. The network prompts the caller to select between either leaving a message at a forwarded location associated with the recipient's DN, whether voice mail or otherwise or to be disconnected and subsequently reconnected with the intended recipient when the recipient's DN is no longer busy. If the caller chooses to leave a message, the network connects the caller's DN with the forwarding DN and a message is left. If the caller chooses to be connected with the recipient when the recipient's DN is no longer busy, the call is terminated, the recipient's DN is monitored so that when the recipient's DN is no longer busy, a call is set up by the network between the caller's DN and the recipient's DN, whereby the information can be conveyed.      Apparatus for implementing this method using the advanced information network (AIN) protocol is also described.
Patent CA-2289177-A1 (CA)
Inventor: HOFELE HANS
IPC: B21D43/05
Filed: 1999-11-09
Abstract: A transport and position system (15), particularly for the workpiece transfer, has a lever mechanism (23) between its driving motors (41, 46) and its output (18), which lever mechanism (23) carries out a step-up. The lever mechanism (23) takes over the guiding as well as the driving of the carrier device (18) which therefore forms the output of the lever mechanism. As the result of the step-up, high accelerations and decelerations can be achieved at the carrier device (18), in the case of which the mass inertia of used linear guides for the bearing of levers and mass inertial of drives moved along play a clearly reduced role. On the other hand, a high positioning precision can be achieved.
