Abstract: An attachment assembly, useful in quickly attaching an object to a panel, is provided with a base assembly having a shaft member extending therefrom and an expandable member having a plurality of fingers disposed on one side of the panel such that, during installation, the fingers radially outwardly expand to clamp the object to the panel. A process of mounting an object to a panel is also provided. The object is attached to the base of the attachment assembly and the shaft member is positioned in an aperture in a panel. The panel is clamped between the fingers and the base upon installation of the attachment assembly.

Abstract: An attachment assembly provides quick attachment of an automotive antenna unit or other object to the exterior of a vehicle. A single worker is able to install the antenna unit or other object with one downward push from the exterior without the need for tools. The attachment assembly also includes an anti-rotation feature to prevent rotation. The attachment assembly can only be removed from the interior, rendering the attachment assembly tamper resistant from the exterior. The attachment assembly can also be mounted on vehicles with various panel thicknesses.

Abstract: A method of control of chemico-thermal treatment of workpieces in a glow discharge comprising the steps of measuring the workpiece temperature, its rate of change and frequency of arc occurrence, comparing the measured quantities with their predetermined values, producing the corresponding error signals, and obtaining a control signal from the latter to control the glow discharge voltage.A device for carrying out the method of the invention comprising a temperature sensor, a rate-of-change-of-temperature sensor, and an arc occurrence frequency sensor having their outputs connected to comparison elements adapted to compare said measured quantities with their predetermined values, and having their inputs connected to the workpieces and to leads of a discharge chamber. The comparison elements have their outputs coupled to the inputs of regulators of the temperature, its rate of change and frequency of arc occurrence, said regulators being coupled to a supply voltage source via a control unit.
