An apparatus, system, method, and program for facilitating the design of electronic assemblies include transmitting a user interface application to a user over a publicly-accessible global network. The user interface application is updated in response to electronic assembly design data entered by the user.

An apparatus, system, method, and program for facilitating the design of a bare board circuit board include transmitting a user interface application to a user over a publicly-accessible global network. The user interface application is updated in response to circuit board design data entered by the user.

A method of manufacturing comprises the steps of providing a batch of articles containing one or more articles in a common step in a process of being manufactured with a machine detectable tag, providing at least one station in the manufacturing process with a detector for detecting the tag, providing a link between the at least one station and a controller, signaling detection by the detector of the presence of the tag to the controller over the link, and assigning the highest priority for processing through the at least one station to the batch.

Manufacturing method and apparatus

A fire-extinguishant system includes a source of extinguishant, such as carbon dioxide, a fusible length of plastic tubing, such as one-half-inch-outside-diameter polyethylene tubing, with the end closed, and a conduit and valve system for connecting the extinguishant source to the fusible tubing. The valving system pressurizes the fusible tubing at a low pressure, and this low-pressure signal is coupled to a pilot input port in the valve system. When this low-pressure pilot signal is interrupted, the piloted valve switches to supply extinguishant at full pressure through the fusible tubing. If the fusible tubing has been melted, such as by a fire, the extinguishant exits through the melted portion to extinguish the fire. The low-pressure pilot signal can, however, be interrupted manually by the valve system. In this case, the full-pressure extinguishant supply to the fusible tube ruptures the tube and releases extinguishant. This provides a manual extinguishant control for the system.

An electrostatic, coating-dispensing apparatus includes an electrode upon which an electrostatic potential is impressed. The electrostatic potential is developed by a switching circuit, autotransformer and voltage multiplier from rectified line voltage. The entire apparatus is housed in a hand-held applicator to which line voltage is supplied. In one embodiment, suitable for the hobbyist, the apparatus includes a socket defined at one end thereof for interchangeably receiving containers holding various colors or types of coating material. Each container includes an electrode for contacting the first-mentioned electrode. The containers are shaped to fit snugly into the socket to hold the two electrodes in contact. An outer end wall of each container has a mesh portion through which charged particles of coating material from the interior of the container pass when the apparatus is activated. In another embodiment suitable for industrial applications, the coating material and any other necessary supplies, such as compressed air, are provided through hoses to the dispensing apparatus. The electrostatic potential supply is sufficiently compact that it can be housed within the hand-held dispensing apparatus.

Hand-held coating-dispensing apparatus

A system for adjusting the flow rate of charged particulate coating material between a device for dispensing the coating material and an article, or 'target,' to be coated by such material to account for factors, such as variations in the profile or contour of the target, or movement of the target transversely to the direction of motion of a conveyor upon which the target is being conveyed past the device or head, which might otherwise cause variations in the thickness of the coating material. The particles migrate in a known manner under the influence of an electrical field toward the target for deposition on the target to coat it at high deposition efficiency. The system continuously monitors the current flow to the target. The system feeds back this current flow related signal to a coating material flow rate servomechanism.

Method for controlling the flow of coating material

A system for electrostatic deposition of a coating on an article from a charging device includes a direct current high voltage supply having first and second terminals across which the high voltage is impressed. The article to be coated is held at a potential substantially equal to the potential on one of the high voltage terminals. The article is suspended for relatively free movement toward and away from the device. The system includes a high-speed switch coupled between the high voltage terminals and a control circuit for controlling the switch. A sensing resistor in the high voltage output circuit monitors the current between the high voltage terminals. The control circuit includes a slope-detecting or fixed difference circuit responsive to the sensed current to detect too-rapid changes therein, such changes being indicative of close proximity of the article to the charging device and the possibility of high voltage arcing therebetween. The fixed difference circuit compares a sampled signal, related to the sensed current by a fixed difference, with a signal related to the instantaneous value of the sensed current to predict a condition conducive to high voltage arcing. The control circuit additionally includes an automatic ranging circuit for comparing a sampled signal related to the actual current through the sensing resistor with a signal related to a predetermined multiple of the instantaneous current through the sensing resistor. The automatic ranging circuit therefore is not concerned with the absolute magnitude of the current through the sensing resistor, as is the slope-detecting circuit, but rather, the automatic ranging circuit considers only the difference between a sampled signal related to current through the sensing resistor and a signal related to the instantaneous value of current through the sensing resistor. The high voltage supply further includes a high voltage transformer having primary and secondary windings. The primary winding includes a supply terminal coupled to a relatively low voltage supply and two terminals coupled to a switching circuit which controls current flow through the primary winding. The resulting voltage variations across the secondary winding are rectified and multiplied to produce the high voltage. A resistive voltage divider senses the high voltage. A regulator coupled between the low voltage supply and the supply terminal regulates the voltage provided to the supply terminal, thereby regulating the high voltage.
