Patent CA-2149585-A1 (CA)
Inventor: PATEL CHANDRAKANT BHAILALBHAI
IPC: H04N5/44
Filed: 1995-05-17
Abstract: Un récepteur radio permet de recevoir des signaux BLR comprenant des codes de symbole descriptifs de signaux numériques, les signaux TVDH étant exemplaires de tels signaux BLR, un syntoniseur sert à sélectionner un des canaux à différents emplacements dans une bande de fréquences utilisée pour transmettre de tels signaux BLR. Le syntoniseur comprend également des mélangeurs pour effectuer plusieurs conversions d'un canal sélectionné à un signal final de fréquence intermédiaire, qui est numérisé par un convertisseur analogique numérique. Un suiveur de phase, opérant sur des portions filtrées passe-bande étroites du signal final numérisé de fréquence intermédiaire se centrant sur sa fréquence porteuse, supprime une portion imaginaire du signal final de fréquence intermédiaire, découlant de la distorsion multiparcours ou d'une incohérence de phase dans les oscillations locales utilisées pendant la conversion de fréquence. Un oscillateur contrôlé numériquement dans le suiveur de phase donne les descriptions numériques de l'onde porteuse du signal final de fréquence intermédiaire à un détecteur synchrone, lequel détecteur synchrone détecte la portion réelle du signal final numérisé de fréquence intermédiaire conformément aux descriptions numériques de l'onde porteuse. Une paire de filtres numériques passe-tout, qui présentent une différence de pi/2 en réponse de phase pour les signaux passe-bande numérisés et sont conçus selon des fonctions elliptiques jacobiennes tels que décrites par C. M. Rader, est utilisée dans le suiveur de phase pour générer les portions réelles et imaginaires du signal final de fréquence intermédiaire numérisé.

Title: Elevator control systems
Inventor: HEIMANN WALTER
IPC: B66B1/28
Filed: 1995-06-05
Abstract: An elevator control apparatus is intended for an elevator having a car and at least one intermediate floor between top and bottom floors thereof. The apparatus includes an upper proximity switch and a lower proximity switch mounted on the car and vertically spaced-apart from each other. There is a vane at each floor for activating the upper proximity switch and the lower proximity switch to produce first and second signals respectively as the proximity switches move adjacent said vanes. There are up latches for each said intermediate floor for changing a state when the first signal is produced and the elevator moves downwardly past each intermediate floor and when the first signal is produced and the elevator is moving upwardly towards each intermediate floor. There is a down latch for each intermediate floor for changing a state when the second signal is produced and the elevator moves upwardly past each intermediate floor and when the second signal is produced and the elevator moves downwardly towards each intermediate floor. Controls are connected to the latches for controlling the elevator movement according to which latches are latched and unlatched. Preferably the latches are operatively inter-connected so only one said latch is latched or unlatched as each signal is produced. The proximity switches may be connected to a car levelling system which levels the car at each floor. Alternatively, the proximity switches may be connected to a car slow down system.

Title: Separation of anti-metal chelate antibodies
Inventor: BEIDLER DANIEL E
IPC: C07K16/44
Filed: 1994-05-03
Abstract: The present invention provides a method for the separation of anti-metal chelate antibodies from non-specific proteins, including antibodies, by applying a preparation containing the anti-metal chelate antibodies to a carboxylic acid derivatized solid support and eluting first with an elution buffer containing sufficient salt concentration to elute non-specific proteins but not sufficient to elute the anti-metal chelate antibodies and then increasing the salt concentration of the elution solution so as to elute the anti-metal chelate antibodies. In one embodiment, the carboxylic acid derivatized solid support is a carboxymethyl resin. Appropriate salts include sodium phosphate, sodium chloride, sodium acetate and sodium sulfate. The method can be used to separate monoclonal or polyclonal anti-metal chelate antibodies from non-specific proteins as well as to separate bifunctional anti-metal chelate antibodies from monoclonal anti-metal chelate antibodies and other non-specific proteins. The method is also useful for separating anti-metal chelate antibody fragments bearing antigen reactive regions from non-specific proteins.

Patent CA-2163937-A1 (CA)
Inventor: SCHELLINGER MICHAEL JOHN
IPC: H04B17/00
Filed: 1995-11-28
Abstract: A unique method improves channel scanning by reducing the time required to scan channels. The method reduces the number of channels which must be scanned using information previously obtained in a scan. If two sets of channels which overlap are scanned in two separate scanning steps (522), information obtained in a first channel scan can be used, thereby eliminating the time required for a second channel scan. For example, if the dedicated control channels and the paging channels of a cellular telephone system overlap, the channels which overlap need not be scanned during the channel scan of the paging channels. The method further reduces scanning time by ending the channel scanning of a particular channel if an undesired channel type is detected (808).

Abstract: A procedure for the manufacturing of an improved condom features a knitted fabric adhered to the condom. The fabric is deformed in a longitudinal sense in relation to its axle, by means of a system through which the fabric, in the shape of a tube, is introduced into a cone. Two parallel conveyor bands with fastening devices are adhered to the fabric. Once the fabric is cut through in the middle of both bands, it is conveniently guided onto the condom matrixes where elastomeric rings deform and fit it tight, The whole set thus thus is ready to be dipped into an adhesive coating and later dried after which drying, electrically heated metallic rings cut away the remainder of the fabric that failed to adhere to the condom. Thus the latter is rolled and readied for packaging.
