Abstract: A tube heating assembly having a heating tube with proximate and distal end portions, a manifold insert disposed concentrically within the heating tube and likewise having proximate and distal end portions, and a pair of end caps removably secured to the proximate and distal end portions of the manifold insert and the heating tube respectively. The manifold insert includes a raised spiral thread on its surface. An electrical assembly such as a resistive path applied to the outer surface of the heating tube is used to heat the tube. The tube heating assembly may be embodied in a system and method for delivering an automotive fluid in a vehicle, wherein the tube heating assembly is installed as a heat exchanger in a fluid delivery path through which the fluid is pumped, preferably in pulses to enhance heating of the fluid.

Abstract: A tubular resistor assembly for use in electrical circuits for controlling automotive accessories, including a tubular aluminum or other metal substrate having watertight walls and open ends for connection to a fluid-carrying system, a resistor of a predetermined magnitude disposed on the tubular metal substrate. A control circuit, incorporating the resistor, controls the operation of one or more automotive accessory. The assembly may be used to intentionally heat a fluid passing through the tubular substrate, the fluid may be used to carry excess heat away from the resistor, or both. Multiple resistive elements may be included for multiple levels of control of such accessories as headlights, fan assemblies, and the like.

Abstract: The present disclosure is to a high current multi-layer chip-type feedthru device that may be composed of multiple alternating layers of conductive material and semiconductor material in a fashion to form a feedthru capacitor with transient suppression properties. The disclosed technology provides a feedthru device with significantly improved current handling capability relative to previously known devices having a similar form factor. The improved current handling capability is achieved by a translation of component geometry that results in a substantial decrease in the feedthru capacitor's internal resistance. The conductive layers interleaved among the layers of semiconductive material are characterized as either main signal carrying conductors or transient grounding electrical conductors. Main signal carrying conductors extend along the generally shorter width of the feedthru device, and are characterized by a substantially wide current path.

Abstract: An integral dual frequency by-pass and transient suppressor device has at least two ceramic semiconductor layers, the upper surfaces of which are formed with electrodes of generally U-shaped configuration. The base portions of the electrodes are exposed at opposite surfaces of the semiconductor layers, the leg portions of the U-shaped electrodes extending toward the base portions of electrodes of opposite polarity. The overlap or registration area of one pair of legs differs from the overlap area of the other leg pair with the result that two capacitors of different values are formed, the capacitors being in parallel and accordingly defining a low impedance path at two discrete frequencies. By varying the conductive paths as a function of the length of the electrode and/or the base of the U, a desired internal inductance is developed.

Abstract: A capacitor array device is described including a multiple capacitor chip for mounting upon an electronic circuit board. The device includes a device body defined by a plurality of dielectric layers and conductive layers arranged in a stack to form a number of adjacent capacitors. Barium titanate may be employed as a dielectric. The capacitor array device includes a plurality of terminal structures electrically connected to the electrode plates. The device typically includes a sintered body of a multilayer ceramic material in which multiple electrode layers are stacked with dielectric layers being located between the electrode layers. Multiple combinations of capacitance values may be used within the array. An array having two, three, four, five, six, or more capacitors may be constructed, such that certain of the capacitors have about the same capacitance value, while other capacitors within the array have other different capacitance values.

Abstract: A symmetrical feed-thru filter construction is provided in a square-shaped chip with corner terminations and unoriented feed-thrus running diagonally across the chip for suppressing transient or undesired frequencies from a signal. The construction can be of either a capacitor or varistor based design and can be altered during manufacture to handle signals of specified strengths.
