Abstract: Abstract of the Disclosure There is disclosed herein an ECL gate using switchable load impedance means to allow the gate to be placed in a low power-consumption mode while preserving the logic state existing at the outputs of the gate at the time it is switched into the low-power mode.  N-channel or P-channel MOS transistors are used as the switchable load impedances.  The gates of these transistors are coupled to a MODE control signal which causes the MOS transistors to switch between high-impedance and low-impedance states. Another MOS transistor having its gate coupled to the same MODE control signal is used as the current source for the bias current to the conventional ECL current mirror.  When low-power mode operation is desired, all the MOS transis-tors are switched to their high-impedance states.  This reduces the bias current flowing through the ECL gate, thereby reducing its power consumption.  The logic states at the output nodes are preserved by virtue of the load impedance of the ECL switching transistors having increased simultaneously with their collector currents having decreased.

Abstract: FREQUENCY SELECTIVE SCREEN HAVING SHARP TRANSITION    ABSTRACT OF THE DISCLOSURE                 A frequency selective screen (18) is employed as a diplexer to separate each of one or more radio frequency signals into first and second bands of frequencies by allowing the first band of frequencies to pass therethrough and reflecting the second band of frequencies. The screen (18) includes an array of discrete, electrically conductive elements (32), preferably copper, formed on a substrate (33) such as a layer of polyimide. The conductive elements (32) possess a geometry which results in an equivalent electrical circuit (50) that exhibits parallel resonance, high impedance within the first band of frequencies and series resonance, low impedance within the second band of frequencies, thereby transmitting the signal in the first frequency band and reflecting the signal in the second frequency band. The screen (18) may include first and second portions (18a, 18b) in which the conductive elements (32) are respectively oriented along different axes to respectively separate horizontally and vertically polarized signals. The screen (18) may be employed in a satellite (10) to separate transmit and receive frequencies.

Abstract: A contact arrangement for switchgear with multiple disconnects by contact points connected in parallel of two contact bridges aligned in a contact actuation link uses a spring collar for a contact pressure spring. The spring collar has cutouts transverse to the spring-action direction into which the contact bridges with the spring collars can be inserted and locked in place transverse to their longitudinal direction. The spring collar is rounded at two facing sliding surfaces in the contact actuation link aligned transverse to the longitudinal direction of the contact bridges. This assures optimal fitting of the contact bridges to the fixed contact components without jamming the spring collar in the alignment.

Abstract: Method for producing a shaped conductor 5, a shaped conductor 5 and a choke which is produced by using a shaped conductor 5. The shaped conductor 5 is produced by coiling conductor 6a-6d parallel around a mandrel 7 and then pulling of the circular arc-shaped conductor formed in this way between pressure rolls 8a, 8b. In this manner, a flat, shaped conductor 5 is produced in which the wires 6 lie in two parallel rows and uniformly around the shape conductor. The choke coil is formed by introducing one or more shaped conductors 5 into each coil 4a-4c in such a way that the wider side of the shaped conductor runs in the radial direction of the choke. By selecting an appropriate number and appropriate thickness of wires in the shaped conductor 5, all the coils can be made essentially the same height in the axial direction of the coil with consideration of the number of turns and current. <IMAGE>
