Title: Automatic equalization method and apparatus
IPC: H04B3/14
Filed: 1972-12-20
Abstract: 1421917 Pulse equalization apparatus XEROX CORP 20 Dec 1972 [30 Dec 1971] 58829/72 Heading H4R In an adjustable equalizer for correcting frequency-dependent distortion, and comprising at least one amplifier, and a plurality of all-pass delay networks, means are provided to introduce different frequency dependent amplitude gains and frequency dependent delays into successive pulse signals of a sequence of pulses from a remote transmitter in order to identify a desired combination of amplifier and/or delay networks and to insert that combination in the path, one possible combination being neither amplifier nor network. Control and insertion of the amplifiers and/or networks which may have different frequency dependent characteristics is effected by logic circuitry 29, Fig. 2, and switches S1-S5 in response to peak-to-average difference readings K1-K2-K3, Fig. 9b, measured in 31 and the response to pulses detected in 27. During the establishment of the desired combination the detected pulses step the apparatus through a predetermined switching programme and the maximum of the successive P-A-D readings is stored in sample-and-hold 33. A latching pulse from comparator 35 inserts the desired combination, i.e. the one giving the highest P-A-D reading when, during a second cycle of the test pulses, the instant P-A-D reading equals or exceeds the stored value. A table of the switching programme is included together with a set of the different delay network characteristics. F.E.T. switches are used, and the system incorporates what is called a compatibility signal generator which effects a control whereby predetermined fixed equalization is inserted if the transmitter to which it is connected is not capable of sending the proper pulse sequence, and a similar insertion is made if the second cycle of pulses fails to produce a latching signal from the comparator, or if the P-A-D voltage is excessive. An alternative arrangement in which the switches are set in response to the receipt of a single sequence of pulses is described.

Abstract: 1412150 Centrifugal pumps GENERAL ELECTRIC CO 21 Dec 1972 [29 Dec 1971] 59072/72 Heading F1C A centrifugal pump comprises a shutter valve 50 located between the impeller 14 and the diffuser vanes 24 and movable between an inoperative position and an operative position, the valve comprising wall means 52 which leave the inlets to all the diffuser passages 26 open when the valve is in the inoperative position, and the wall means substantially completely closing the inlets to individual diffuser passages when the valve is in an operative position while leaving the inlets to the remaining diffuser passages substantially completely open. The wall means 52 is of cylindrical form and is movable axially either by a mechanical linkage or, as shown, by a piston 60. When the valve 50 is moved from a completely retracted position to a first operative position, it completely closes four of the twelve diffuser passages 26 while leaving completely open the eight remaining diffuser passages, each of which is in alignment with a corresponding slot 54, 56 or 58. When the valve 50 is moved further to a second operative position, the four passages aligned with the short slots 54 become closed so that four passages remain open. When the valve 50 is in a third operative position, the two passages aligned with the larger slots 56 are closed, so that only the two passages aligned with the longest slots 58 remain open.

The substrate 26 may comprise an insulating layer on a carrier of metal or semi-conductor, or may, as shown, consist of a body of glass, ceramic or alumina. The substrate metallization pattern 28, 29 may comprise Al or successive layers of Ti, Pt and Au. The body contact pattern may be made of Al or Mo/Au but preferably consists of a platinum silicide/Ti/Pt/Au layered structure. Both substrate and body patterns may be multi-level structures, adjacent levels being separated by insulating material. The interconnections 31, 32 may be vacuum deposited and/or electroplated Au layers. Alternatively the body and substrate metallizations may be bonded directly together by soldering or thermocompression, and in the latter case the beam leads 13, 17 are reinforced by electroplating extra material. As shown the semi-conductor body consists of an N-type epitaxial Si layer 2 on an N+ -type Si substrate 1. Etching to expose the beam leads 13, 17 is preferably by means of an etchant which preferentially exposes the (111) surfaces, the major faces of the body 1, 2 lying in a (100) plane. A suitable etchant is hydrazine and water. An Al mask 25 limits the extent of the etching. The parts of the insulating layer 7 in contact with the beam leads 13, 17 may also be removed as shown, or may be left intact. The invention is also applicable to diodes or to monolithic integrated circuits, and device isolation in the latter case may be effected by reverse biased PN- junctions or by means of grooves etched through the semi-conductor body after mounting on the substrate 26. A hybrid integrated circuit including a plurality of flip-chip, beam-lead components of the type shown mounted on a common substrate and interconnected by the substrate metallization pattern is also described.
