Patent EP-0610694-A1 (EP)
Inventor: ALPAUGH WARREN A
IPC: H05K3/26
Filed: 1994-01-20
Abstract: Disclosed is a method of drilling, desmearing, and additively circuitizing a printed circuit board. The printed circuit board is drilled under conditions which produce glass and polymer smeared vias and through holes. The particulate debris is removed by vapor blasting the drilled printed circuit board. Next the printed circuit board is soaked in a solvent to swell the drill smear on the circuit interplanes of the printed circuit board. This solvent is then removed by entrainment in a gas, and a stream of an aqueous, acidic, oxidizing solution is passed through the printed circuit board holes to remove swollen smear in the thru holes and produce an etchback of conductors. After a water rinse an aqueous reducing solution is passed through the printed circuit board to reduce and remove aqueous acidic oxidizing solution, e.g., residual aqueous acid oxidizing solution. The printed circuit board is rinsed to remove the aqueous reducing solution. The surface of the printed circuit board is then seeded, the intended circuitization is photolithographically defined on the printed circuit board, and the circuitization, including the surface circuitization and the plated through hole circuitization, is additively plated.

Abstract: The current overshoot compensator comprises a capacitor (2), a self-regulating power converter (3) and a reactive coil (4), connected to the electrical equipment (1) which is generating current overshoots. The current induced in the coil is equivalent to the inverse sum of the current overshoots, plus a sinusoidal current component which compensates for losses generated by the compensator itself. The required value of the inverse sum of current overshoots is obtained by subtraction of high order harmonic components from the total current through a filter (5) and inverter (6). This value is entered with the loss compensation current into a Schmitt trigger (7), which generates control signals for the power converter.

Abstract: A pair of bi-fold lids (10) covers a container (1) having a depth dimension that is less than half the width dimension of the container. Each bi-fold lid has front and rear sections (11,12) that are hinged together along a hinge axis (14). The hinge axis is reinforced by adjacent flanges (31,42) that overlap one another when the lids are in their closed position. When the lids are open, the front and rear sections fold over on one another to reduce the extent to which they hang down adjacent the sidewall of the container. This permits a container of short height or shallow depth to have lids.

Abstract: A system and method are disclosed for controlling a shift even in a transmission (14) wherein a shift actuator (30,48) develops a force to effect the engagement of a clutch collar and a gear. The method comprises detecting when a non-fully engaged condition of the clutch collar and the gear occurs, indicating either a tooth butt or torque lock condition, and then pulsing the shift actuator (30,48), when the non-fully engaged condition is detected, between a relatively low force and a relatively high force to disturb the clutch collar and the gear out of the non-fully engaged condition. The detecting step comprises examining either the axial position of the clutch collar or the axial position of a shift rail operatively connected to the clutch collar with a rail position sensor (43). Preferably, a signal having a modulated pulse width and a frequency of between about 5 and 20 Hertz is sent to the shift actuator. The system which embodies this method is disclosed in the forms of an automated mechanical transmission having sliding clutch collars (122,124,126) and a transmission system having a standard friction master clutch interposed between the engine and the transmission.

Abstract: The painting process includes application of the paint coating as normal on to the vehicle surface - which may be ferrous, non-ferrous, plastic or composite. Before reticulation of the paint, the surface is treated with ultrasound radiation. The paint is then subject to the normal processes to accelerate and complete the coating. The irradiation is achieved with a number of ultrasound transducers (6-10) surrounding the object to be painted. They include supports which allow them to be moved in a direction perpendicular to the vehicle surface. The transducers define a band of irradiation about the vehicle which may then be moved relative to the transducer assembly.

Abstract: Une tête artificielle (2) et une pluralité de microphones monophoniques discrets (8, 10, 12) sont utilisés pour enregistrer une ou plusieurs sources de son. Les signaux (14, 16, 18) provenant de chacun des microphones (8, 10, 12) subissent alors une synthèse binaurale basée sur les propriétés acoustiques d'une tête humaine réelle ou de la tête artificielle (2), et les signaux (4, 6) provenant de la tête sont égalisés en utilisant les fonctions de transfert air-oreille de la tête artificielle (2) ou de la tête réelle. Les signaux résultants sont combinés en additionnant les canaux individuels gauche (48) et droit (50) et ces signaux additionnés (52, 54) sont ensuite compensés par diaphonie transaurale (56) pour fournir des signaux de canaux finaux gauche et droite (58, 60) adéquats en vue de l'engistrement ou de l'écoute, ce qui permet de produire un effet acoustique tridimensionnel pour un utilisateur écoutant via des écouteurs et des haut-parleurs.

Abstract: L'invention concerne un procédé permettant de protéger le bois contre des réactions indésirables dues à des micro-organismes, ainsi que du bois protégé contre les moisissures et les champignons du bleuissement et de la pourriture. Avec ce procédé, on traite le bois à protéger avec une substance pouvant inhiber la croissance de micro-organismes en pénétrant dans ce bois au-delà de ses parties superficielles. La substance utilisée dans le procédé inventé est un agent complexant, l'EDIA (acide éthylènediaminetétra-acétique) par exemple, qui peut se lier aux métaux de transition présents dans le bois. On imprègne d'abord le bois d'une solution aqueuse contenant l'agent complexant qui est ensuite précipité à partir de la phase aqueuse. Cet agent complexant peut être précipité par exemple par abaissement du pH du bois ou par modification de la température du bois après l'imprégnation. Selon l'invention, l'agent complexant précipité dans le bois forme un dépôt de réserve et, par redissolution à partir de ce dépôt, la substance peut se lier aux métaux de transition qui pénètrent dans le bois par l'eau de pluie ou la pollution.

Abstract: An electronic security system includes an electronic lock mechanism (104) and an electronic key (101), each of which is provided with a microprocessor controller and a memory storing data including an ID code and encryption key codes. The lock microprocessor may either change ID codes stored in it's memory or encrypt a seed number to be used for determining access to the lock. The key can only be used to access the lock either once or for a limited number of successible times, and must thereafter be reprogrammed by a host computer (301) to be loaded with either the proper ID code or the appropriate encryption key code for that lock. The electronic lock operates a solenoid (1624) which retracts a bolt-blocking mechanism that prevents the unlocking of the bolt even when a key having the correct mechanical key cuts is inserted into the lock. Power for operating the electronic lock as well as the solenoid is provided by a power supply within the key. In a preferred embodiment the key unit is composed of a handheld computer witha separate internal circuit board which stores key code information and performs encryption/decryption functions. A novel electronic T-lock (1340) assembly is also provided for use with vending machines and the like.
