Title: Cable strain relief for a shielded electrical connector
Inventor: REED CARL G
IPC: H01R9/03
Filed: 1993-04-14
Abstract: An electrical Connector (4) terminated to signal wires (SW) of a shielded electrical cable (C) having a drain wire (DW), has an insulating housing (8) containing electrical terminals having contacts (40) electrically connected to the signal wires of the shielded electrical cable (C).  A metal shield (14) covering the lower part of the housing (8) has a grounding clip (48) connected to the rear wall (28) of the shield (14) by means of a strap (62).  The grounding clip receives an end portion of the cable (C) from which the signal wires (SW) extend to the contacts (40) of the connector (4).  The drain wire (DW) is wound in a circuitous path about tabs (58) of the grounding clip (48).  The grounding clip can be bent about the strap (62) to lie in a channel (36) between two rows of the contacts (40) of the connector (4), after the grounding clip has been wound about with insulative tape (T).  The drain wire (DW) accordingly provides strain relief, if the cable (C) is inadvertently pulled, for the electrical connections between the contacts (40) and the signal wires (SW).

Abstract: Divulgation d'un procédé pour purifier des paraffines linéaires, au cours duquel on met en contact un circuit d'alimentation d'hydrocarbures, contenant des paraffines linéaires contaminées par des composés aromatiques, des composés soufrés, azotés ou oxygénés et des corps colorés, et contenant également jusqu'à 5 %, en poids, d'agent de désorption provenant du recyclage d'effluents, avec un adsorbant solide comme de la zéolite NaX ou de la zéolite MgY. Après adsorption, on fait désorber l'adsorbant à l'aide d'un composé aromatique substitué par un alkyle, comme le toluène. Pendant la désorption, l'effluent initial du cycle d'adsorption contiendra des teneurs en agent de désorption et pourra être recyclé vers le circuit d'alimentation d'hydrocarbures. Avant l'élimination des impuretés de l'adsorbant par désorption, l'agent de désorption déplace des paraffines linéaires interstitielles qui sont également recyclées vers le circuit d'alimentation d'hydrocarbures.

Title: Procede de production de gros monocristaux
Inventor: VICHR MIROSLAV
IPC: C30B33/08
Filed: 1993-06-01
Abstract: L'invention est une méthode de production de monocristaux de grande taille. Dans l'une des concrétisations de l'invention, un monocristal de diamant de qualité électronique d'une épaisseur de 100 à 1 000 micromètres environ et d'une aire substantiellement supérieure à 1 cm2 et ayant une perfection cristalline élevée qui peut être utilisé dans les applications électroniques, optiques, mécaniques et autres est produit. Une couche de diamant monocristallin est d'abord déposée sur un cristal maître servant de germe et les couches de diamant résultantes peuvent être séparées du germe par des moyens physiques, mécaniques et chimiques. Le germe d'origine peut être reconstitué par croissance épitaxiale pour être réutilisé comme germe dans les opérations ultérieures. Des germes de diamant monocristallin de grande taille peuvent être produits en combinant des germes orientés de taille plus petite par une fusion épitaxiale latérale. Étant donné qu'il n'y a pas de limite quant au nombre de répétitions des combinaisons de germes, on peut fabriquer des plaquettes de diamant autonomes de taille comparable à celle des plaquettes de silicium.

Title: Process for the manufacture of safe and easy-to-transport pellets of chrysotiles asbestos
Inventor: DELVAUX PIERRE
IPC: C04B14/40
Filed: 1993-11-16
Abstract: ABSTRACT OF THE DISCLOSURE   Disclosed is a process for manufacturing of pellets of chrysotile asbestos fibers, wherein asbestos fibers containing from 5 to 20% by weight of water are pelletized to form wet pellets that are subsequently dried until their residual water content reaches 0 to 1% by weight. Then, an aqueous solution or suspension of a substance compatible with the intended use of the pellets is sprayed onto the same to form a selective protective coating that eliminates release of asbestos dust and air-borne particles. The obtained pellets have excellent mechanical properties that make them easy to handle, thereby allowing safe and easy transportation of chrysotileasbestos in bulk.

Patent CA-2104619-A1 (CA)
Title: Electronic lamp ballast
Inventor: TARY TAMAS
IPC: H05B41/285
Filed: 1993-08-23
Abstract: ABSTRACT OF THE DISCLOSURE            An electronic ballast for discharge lamps comprises an open loop configuration of an impedance converter first stage and an inverter second stage linked by a limiting control stage.  The impedance converter stage presents its load, passive or active, as input resistance.  It draws a continuous current, through large RFI/EMI suppressing input inductors, which is switched discontinuously through a tank circuit using an energy transfer relationship based on the switch on-time and the inductance and capacitance of the tank circuit.  The impedance converter stage supplies unregulated power to the inverter stage which operates stably at a fixed frequency.  If an imbalance such as an overcurrent condition or an overvoltage condition develops in the system, the limiting control stage temporarily preempts the converter switching until stability is reestablished.

Filed: 1993-01-07
Abstract: Trousse et méthode d'analyse pour la détection multiple, rapide et sensible, de pesticides à base d'organophosphates et de carbamates.  La méthode fait appel à une préparation de cerveau d'insecte comportant un mélange de récepteurs d'enzymes, avec des sites qui interagissent avec ces pesticides.  Les pesticides modifient ou entraînent une réduction significative des activités de la préparation de cerveau, qui sont régies par une corrélation inverse avec la quantité de pesticide présente dans l'échantillon.  L'activité est mesurée à l'aide d'analogues ou de substrats traceurs qui, après exposition de la préparation de cerveau, sont modifiés; les changements sont mesurés par une réaction photoémissive.  Dans l'une des versions de l'invention, comme dans le cas de l'acétyl-luciférine, on a constaté que l'hydrolyse d'un dérivé de la luciférine en D-luciférine par une préparation de cerveau d'insecte s'est révélée extrêmement sensible pour les organophosphates et les carbamates.  La luciférine libérée par la réaction est oxydée par l'enzyme luciférase et l'adénosine-triphosphate (ATP), un donneur d'énergie, et émet de la lumière mesurée par bioluminescence ou chimioluminescence.

Title: Digital radio mobile frequency supervision
Inventor: LINDELL KARL BO
IPC: H04B17/00
Filed: 1992-05-19
Abstract: The frequency stability of the signals transmitted by a plurality of mobile stations to an associated base station within a radio network is supervised by first generating a reference signal at the base station. The signals received from the mobile stations are compared to the reference signal and a difference signal is generated. The difference signal is compared to first and second error values and if the difference exceeds the first error value, the mobile is summoned for a service adjustment. If the difference exceeds the second error value, the mobile is disabled from further transmissions.

Title: Container handling equipment
Inventor: PAMMENT JONATHON W
IPC: B60P1/54
Filed: 1993-10-19
Abstract: ABSTRACT      TITLE: IMPROVEMENTS IN CONTAINER HANDLING EQUIPMENT A container handling system is provided which comprises a lever arm pivotally mounted to a support such as a transport vehicle, a jib carried by the lever arm, a hook or bail attached to the jib adapted to engage a corresponding bail or hook on an upper end part of a container, and an auxiliary bail or hook pivotally mounted on the jib adjacent its free end. Such a handling system is capable of lifting different types of containers onto a transport vehicle. For instance, a container having a bail on its upper end part can be lifted by actuation of an hydraulic or pneumatic mechanism to move the lever arm about its pivotal mounting so that the hook engages with the bail on the upper end part of the container, and a container having a hook on a lower end part thereof can be lifted by moving the auxiliary bail into engagement with the hook on the container.

Inventor: DENT PAUL W
IPC: H04B7/26
Filed: 1993-04-13
Abstract: A Code Division Multiple Access (CDMA) communication system which contains a calling channel which is used to inform silent mobiles that they are being called. In the system, the calling channel is chosen to be the strongest overlapping signal so that it reaches mobiles which are located on the cells extreme boundaries. The interference other signals experience because they overlap with the calling channel may be avoided by having the mobiles first demodulate the calling channel signal and then substract it out before demodulating their own signal.
