Title: Apparatus for adjusting equalizers for signal transmission systems
IPC: H04B3/14
Filed: 1971-10-07
Abstract: 1326800 Automatic equalizers WESTERN ELECTRIC CO Inc 7 Oct 1971 [12 Oct 1970] 46679/71 Heading H4R In an arrangement for setting up an equalizer 13 which comprises a number of "bump" circuits a swept frequency test signal is applied to the line 12, from oscillator 11, and its level at the receiver is compared with a reference level at 16. Control signals for the respective "bump" circuits are derived by integrating the difference signal developed by comparator 16 during the period that the test signal is scanning across the frequency band of the respective bump circuit. As described the signal received from the line 12, after passing through the equalizer 13 is limited at 17, and applied to frequency selector 18 comprising a counter circuit which is repsatedly reset and counts for a predetermined period to determine the incoming frequency. As the test signal passes through the band limits of the respective bump circuits the outputs f 1  to f s  are enabled in turn causing the respective bump selectors 19 to be enabled when the appropriate frequencies are being received from the line. The bump selector, on its outputs A, B, and B causes resetting of integrator 21, when the received frequency enters the bump circuit test band, and then read out of the integrated signal, via a to d 26, when the received frequency leaves the bump circuit test band. In addition the bump selector enables the appropriate one of gates 32 to apply the control signal to the appropriate bump circuit. Logic circuits for the frequency selector and bump selectors are described with respect to Figs. 3 and 4 (not shown).

Title: Electric induction heating apparatus
IPC: B32B15/01
Filed: 1962-12-14
Abstract: <PICT:1021565/C6-C7/1> Apparatus for continuously heating metal strip by induction, the strip is moved through a primary induction coil, and a portion of the strip advancing towards this coil and a portion of strip leaving it are both in contact with a bath of electrically conductive fluid, e.g. molten metal or a conductive salt, to form a closed secondary loop through the strip and bath.  As shown, incoming strip S is initially heated by contact with the outgoing strip in a narrow portion 5b of chamber 5, and is then passed through a bath of lead 39 maintained molten by heater 33.  After passing through two transformer cores 13, 14, the strip returns to the bath 39 which also acts as a quench. Within the cores 13, 14 the strip passes through metal tubes 22, 23 lined with firebrick and suspended from a chamber 24 filled with inert gas or with gases or chemicals for additionally treating the strip.  An insulating joint 22a is provided in tube 22 so that there is no closed electrical circuit through tubes 22, 23. The cores 13, 14 comprise apertured laminations of rectangular shape, each core being provided with two series-connected windings, one on each side of the strip.  The cores 13, 14 and sheaves 15-19 may be mounted between metal sheets 11 which may also support a thermal barrier 34 which partially divides the bath 39 into two portions at different temperatures.  By lengthening the sheaves, two or more strips, moving in paths parallel to that shown, may be treated simultaneously.

In a photoconductive target comprising a mosaic of P-type regions at one surface of an N-type substrate the remainder of the surface being covered with a resistive film, any defective PN junction elements are covered with a resistive oxide layer by anodization. This prevents the electron beam from attempting to charge the defective units and hence produces a dark spot rather than a bright spot in any resulting display. As shown, one surface of an N-type substrate 12 is covered with a resistive film 14 in which a mosaic of windows are etched. An impurity is diffused-in through the windows to form the P-type regions 13 defining junctions 15 with the substrate. The opposite face of the substrate on which the optical image L is focused may be provided with an antireflection film 16. The wafer is then subjected to an anodization step during which the good junctions 15 are reverse biased so that no current flows but defective junctions 15a pass a current which results in the formation of a resistive oxide layer 22 in the associated windows. The wafer may be lightly etched to remove any oxide layer formed in the windows of the good elements. The anodizing step may be performed in an electrolytic solution or preferably in an ionized atmosphere containing oxygen molecules. The gas anodizing step may be performed after the target is mounted in its operative position.
