Title: Process and apparatus for the wave soldering of circuit boards
Inventor: GIACOBBE FREDERICK W
IPC: B23K1/08
Filed: 1995-02-20
Abstract: A circuit board (26) is wave soldered as it is carried by a conveyor (30) through a solder wave (16); established in a solder reservoir. Disposed on both sides of the solder wave are gas plenums (240, 250) which discharge shield gas. Each gas plenum includes a top wall (245, 255), a side wall (246, 254), and a bottom wall (243, 253). The side wall is spaced horizontally from the wave, and the bottom wall is submerged within the solder (11). The side and (optionally) top walls include orifices (245, 255) for directing shield gas: (i) at high velocity toward the solder wave to protect the solder wave with an atmosphere of shield gas, and (ii) upwardly toward an underside of the circuit board to strip entrained air therefrom. Instead of being submerged within the solder, the bottom wall could be spaced above the solder and provided with orifices to emit shield gas downwardly between the plenum and solder reservoir to create an inert atmosphere above the solder. A divider (70, 270) disposed within the plenum forms sub-chambers communicating with orifices in respective walls of the plenum so that different gas velocities can be entitled from the orifices. The gas plenums can be rotatably adjustable and further adjustable either vertically or horizontally.

Patent CA-2183043-A1 (CA)
Inventor: KEMP WILLIAM HARRY
IPC: G01F23/26
Filed: 1996-08-09
Abstract: A carrier frequency based system employs a capacitive probe which is located at a predetermined desired fluid detection level in a fluid containing vessel. The probe forms one plate of a capacitor where the other plate is formed by the fluid in which the probe is immersed. A carrier frequency is injected into the fluid by means of a suitable oscillator and at a frequency which is close to the system resonant frequency. When the probe is immersed in fluid, the probe will receive a predetermined carrier frequency of an amplitude determined by the system. The output of the probe is coupled to suitable sensing circuits which monitor the amplitude of the signal frequency coupled to the probe. When the fluid level recedes and therefore a portion of the probe or the total probe is out of fluid, the capacitance of the system changes. A different signal from the injected carrier frequency is now applied to the probe indicating to the sensing circuit that the probe is not immersed and therefore indicating an alarm condition. The output of the sensing circuit is monitored by control circuitry which can operate an alarm indicating to the user that the probe is not fluid immersed and that preventive measures should be taken. The fluid sensing probe utilizing the carrier injected frequency can discriminate between fluid and foam, "probe fouling" and probe shorting and is relatively fail proof as compared to prior art systems.

Abstract: In order to provide a packet transfer scheme in which various data can easily be used commonly with other communication methods and a packet can be transferred at a high speed, a mobile communication system comprises a database (20) for storing an identification number of a mobile terminal (40) and location information indicating a zone in which the mobile terminal is currently located, a packet switch (10), and another packet switch (30) capable of communication when the mobile terminal (40) is located in a zone under the packet switch (30). The packet switch (10) inquires of the database (20) about the location information of the mobile terminal (40) when the packet switch (10) receives a packet addressed to the mobile terminal (40).  When the mobile terminal (40) is located in the zone under the packet switch (30), the packet is transferred to the mobile terminal (40) through the packet switch (30). Owing to this arrangement, the number of packet switches necessary for transferring the packet to the mobile terminal is two at the most. Thus, the packet can be transferred rapidly.

Abstract: A method and device for reeling a paper or board web, wherein a first reel spool is in a reeling position in nip-defining relationship with a reeling cylinder and an empty second reel spool is placed in a stand-by position, the web is carried on a belt until it is reeled onto the first reel spool and the belt is guided in a run over the reeling cylinder and a guide roll, the first reel spool being transferred from the reeling position and pushed by the guide roll to a change position and the second reel spool is moved to the reeling position when the reel formed on the first reel spool is complete. The reeling of the web is transferred from the reel formed on the first reel spool to the second reel spool by cutting the entire width of the web by initially cutting a middle region of the web to form a tip and then extending the tip to side edges of the web, blowing the tip onto the second reel spool when the second reel spool is in the reeling position, and applying an adhesive proximate a rear edge of the web reeling onto the first reel spool in advance of a cut line separating the web reeling onto the first reel spool and the tip simultaneous with the cutting of the entire width of the web. The adhesive is applied at a uniform distance from the cut line so as to glue and fix the rear edge of the web to an underlying web portion of the web reeling onto the first reel spool.

Abstract: L'ouverture à la base de la conduite d'alimentation d'un silo se doit - pour des fins de sécurité - d'être hermétiquement fermée lorsque les manoeuvres de transbordement du produit ensillé sont complétées. Il est pratique courante d'exécuter cette opération par la mise en p lace d'un panneau de veneer retenu en position par un morceau de 2" x 4" placé à la verticale et à la serre avec le sol. En second lieu, une personne doit régulièrement grimper par l'échelle à l'intéri eur de la conduite d'alimentation du silo afin d'effectuer des travaux de maintenance. L'accès est aussi nécessaire pour changer, au besoin, de porte de service du silo en fonction de la hauteur d u produit ensillé. Travaillant seul, dans un endroit restreint et isolé à l'intérieur du silo, la p ersonne n'a aucun moyen de communication pour obtenir de l'aide ou du secours en cas de malaise, d 'incident ou d'accident. Dans la présente invention, le clapet du silo fixé au mur est retenu par une tige montée sur un ressort, lequel sert a faire pivoter avec peu d'effort le clapet du silo à 90 degrés lorsque le cordon de mise en service relié au levier d'engagement est actionné. Dans sa cou rse de déplacement lors de l'ouverture, le clapet de silo active mécaniquement le systè me d'alarme qui est pré-programmé à cet effet pour une période déterminée. Dans le sens inverse, lors de la fermeture, l'alarme est désactivée.
