Abstract: A terminator for multiple electrical conductors has a forwardly projecting ground contact provided on the ground structure thereof. A corresponding receptacle has a die cast frame to which nosepieces are attached. Cantilevered contact elements extend from contact blocks and are received in windows provided in the nosepieces.

Abstract: A ground plane shield device for retro-fit application to a connector having columns of tails with a right angle bend that is previously mounted to a board includes a generally U-shaped conducting member having a closed face and three open faces. Two of the faces have clips which are arranged in corresponding pairs and which respectively grasp and electrically interconnect the member to a first and a second portion of a tail in one of the columns that is connected to ground potential.

Abstract: A method and apparatus for improving the bandpass characteristic of an acousto-optic tunable filter in which two optically birefringement crystal parts are oriented so that their respective optic axes are tilted with respect to each other. The amount of tilt as well as the angle of incidence to the first part is selected so as to subject the light to a first bandpass characteristic in a first part of the crystal and a second bandpass characteristic in a second part of the crystal such that the bandpass characteristics have a common center frequency. When the bandpass characteristics have a ratio of 1.5, sideband suppression is significantly improved.

Abstract: Photodefined pin and guide arrangements on a connector and a printed wiring board are used to obtain an alignment between the connector and the printed wiring board. A clamp fixed to the connector housing squeezes the connector contact fingers to the connector pads of the board to engage pads and fingers which have been guided into an overlapping position by the guide and pin arrangement.

Abstract: A forward-reverse pulse cycling anodizing and electroplating process power supply wherein the forward-reverse cycle time, the ratio of positive to negative pulses during the cycle time, the width of the individual pulses and the voltages of the pulses are controlled. During the cycle time a series of discrete positive pulses are supplied during the first portion of the cycle, followed by a series of discrete negative pulses during the remainder of the cycle. The cycle is then repeated for as long as the power supply is energized. The discrete pulses supplied are portions of sinusoidal current waves. Triggerable unidirectional current conducting devices, disposed between the alternating current power supply and the electroplating load, are triggered into conduction at a selected point by a firing angle control circuit. Using the disclosed electroplating process power supply it is possible to hard anodize copper bearing aluminum alloys without etching.
