Title: Improvements in or relating to secrecy systems
Inventor: KING KENNETH CEDRIC ARTHUR
IPC: H04K1/04
Filed: 1962-06-18
Abstract: 980,141. Secret transmissions. TELEPHONE MANUFACTURING CO. Ltd. May 23, 1963 [June 18, 1962; July 4, 1962], Nos. 23432/62 and 25622/62. Heading H4R. In a speech secrecy transmission system the speech is transmitted alternately clear and inverted the switching between the two conditions being controlled by beating together the outputs of two oscillators which are provided at one station and the outputs of which are fed over the line to the other station, the switching occurring about 10 times per second. The drawing of the first Provisional Specification shows a system in which speech is passed either direct to line or through an inverting modulator MO to the line depending on the condition of switches S1 and S2, the operation of the switch being controlled from two oscillators 01 and 02, at 2,500 and 2,540 c.p.s. respectively, the outputs of which are beaten together to extract the 40 c.p.s. difference signal which is passed through a divider D1 to produce a 10 c.p.s. signal which is used to operate the switches S1 and S2. The outputs of oscillators 01 and 02 are also applied to the line so that they may be utilized at the receiver, by modulating one signal with the other, to control the switching of the receiving apparatus. In an alternative form, the second Provisional drawing (not shown), the inverter unit is switched at each station from the transmit line into the receive line so that it is constantly in use. The Specification also describes a system in which the switching is controlled by dividers fed from a single oscillator provided at one station and feeding the other station over the line.

Title: Image probe and density analyzer
IPC: H04N5/33
Filed: 1972-05-19
Abstract: 1396961 Image analysis ANTECH Inc 19 May 1972 [11 June 1971] 23749/72 Heading H4F An image analysis system in which video signal levels lying within a selected range are displayed with a contrasting brightness or colour as compared with the overall image, wherein the system has controls which enable the mean level and the width of the range to be independently selected. In Fig. 1 the video signal from a television camera 3 is fed via a potentiometer 7 so that a predetermined level of the signal is supplied to an analyser 9 which includes a voltage window detector 11 which delivers a gating output voltage to unblock an amplifier 16 when the voltage level of the video signal lies within limits preselected by controls 13 and 14. Control 13 adjusts the mean level (e.g. X or Y, Fig. 2) of the selected video voltage range, and control 14 adjusts the width (e.g. a to b or c to d, Fig. 2) of the selected voltage range. The gain of amplifier 16 may be controlled by control 19. A second voltage window detector 31 is also shown in Fig. 1 so that two ranges may be selected simultaneously. The video signal is also fed via an adjustable potentiometer 21 and an attenuator-amplifier 22 to an output terminal 18 where the segmented image from amplifier 16 is combined therewith and both displayed on the display monitor 29. Since no signal may be passed to output lead 24, synchronization of the monitor 29 is ensured by the path 41 including sync. stripper 36, or by the path 48 from the camera control 4. Detailed description of suitable voltage window detectors 11, and their associated controls 13 and 14 is given with respect to Figs. 3, 4 and 5, not shown, the latter of which includes the capability of displaying the video signal within the window limits or a quantized or normalized display thereof, with or without the full image signal. In addition the video signal within the window limits may be inverted or a differentiator, filter or transient generator may be disposed in the quantized or normalized signal path. Selected density ranges may be displayed in different colours (Fig. 6, not shown), the full image signal being displayed in black and white, i.e., all three colour guns are excited. In a further embodiment (Fig. 7, not shown) the voltage range of the selected window is split into eight smaller voltage ranges which are displayed in six different colours (the extreme smaller voltage ranges being displayed as white), the system including an encoder responsive to the magnitude of the video signal to generate unambiguous sets of digital code signals each corresponding to the smaller voltage ranges which when decoded supply different control signals to a colour television display. The image analysed may be an infra-red image.

Class 55 (2) Coke oven &c. gas is purified in two stage counter-current washings respectively to remove hydrogen sulphide &c., and ammonia, the liquor from the'first stage being distilled and the vapours cooled to, about 65‹-75‹ C to obtain a deacidified ammonia-enriched liquor. which is mixed with liquor from the second'stage and returned to the first. Part of the liquor from the second stage may be supplied directly to the still. De-tarred, dephenolized coke-oven gas ascends a two-part washer 1, 1a in counter-current to water supplied through pipe 3 to the upper part 1 and ammonia-enriched wash liquid introduced to the lower part 1a through a pipe 7. Effluent from the bottom of the washer is pumped to a still 11  with a lime leg 11a and vapours therefrom at about 100‹ C. and led to a condenser 13 and thence to a saturator 15 followed by a separator 22. Liquid from the separator with other ammoniacal condensates may be returned to the still through a pipe 24 opening into pipe 9 which may also be joined by a pipe 25 connected to an outlet pipe 5 from the upper part 1 of the washer. In one method of operation, discharge from part 1 is mixed with discharge from the condenser in a receiver 6 which feeds pipe 7. To enrich this wash liquid with free ammonia some of the effluent from part 1 may pass to the still and liquor returning from the condenser through a pipe 28 may be concentrated by means of a small additional still and vapour cooler disposed in the pipe. The plant may be operated without em-. ploying part la for washing out the sulphur content; effluent from part 1 may pass direct to the still or first circulate through part 1a, and the condenser 13 is cut out.

A component the resistance of which switches from a high to a low value at a threshold voltage is operated at its rated maximum current. A typical device suitable for use in this way is made by vacuum depositing aluminium on a molybdenum plate, reducing the aluminium to a series of frusto-conical islands by a photoresist masking and etching technique, depositing silicon monoxide around and over the islands, grinding to re-expose the islands and then removing them by etching in sodium hydroxide. The resulting frusto-conical holes are filled with a suitable amorphous semi-conductor material by vapour deposition through a mask. After grinding the semi-conductor flush with the top of the oxide layer molybdenum contacts are deposited through a mask and conductors attached to them to provide a mosaic of devices with a common electrode constituted by the molybdenum plate. Suitable semiconductor materials are specified mixtures of tellurium and germanium; tellurium, germanium, and arsenic with or without silicon; and tellurium, arsenic, zinc and silicon.
