Patent GB-528150-A (GB)
Abstract: 528,150. Dyes. MAY, P. (Sandoz, Ltd.). April 28, 1939, No. 12771. [Class 2 (iii)] Sulphonated anthraquinone dyes are obtained in the form of their lithium salts by treating the free sulphonic acids with lithium hydroxide or carbonate, or by double decomposition of the alkaline earth metal salts with lithium carbonate or sulphate. The process is particularly applicable to anthraquinone dyes having a sulpho group in the 2-position or a sulphonated arylamino group in the 4-position, and a hydroxyl, amino or substituted amino group in the 1-position ; where the sulphonated arylamino derivatives are used, the 2-position may be substituted by a halogen atom. The process is also applicable to anthrapyrimidons having a sulphonated arylamino group in the 4-position. The solubilities of the lithium salts of a number of such dyes are contrasted with the solubilities of the corresponding sodium salts, the lithium salts being much more soluble.

In a diffraction apparatus a collimator 32 directs a beam of X or gamma radiation from source 30 towards a crystal 34 in holder 36; the undeviated beam is stopped by trap 40 from reaching the gas-type detector 20, but the diffracted beam, for example 42, impinges on a cathode member 24 of detector 20. The Xray or #-ray photon enters the space between cathode 24 and an auxiliary grid electrode 26, here electrons produced by the ionisation of the gas in the detector migrate towards and through the auxiliary electrode 26 and enter the space between the auxiliary electrode 26 and the anode 28. Between these electrodes, the potential is sufficient to produce avalanche phenomena, which phenomena produce in the gap an image of the diffraction pattern of the crystal which image is recorded photographically e.g. on camera 46 or electronically via an image intensifier and TV system (Fig. 3, not shown). For photographic recording, the potential between 26 and 28 is such as to produce sparks between the two electrodes, and the anode 28 may be transparent and/or coated a layer of a luminous substance having a persistence of one second, the spark pattern being photographed for example through transparent wall 25. Alternatively the voltage between 26 and 28 is selected to avoid the formation of sparks and the image due to the avalanche phenomena is projected on to the photocathode of an image intensifier and thence to a TV tube. The cathode of the detector e.g. 24 is preferably a beryllium window.

Filed: 1972-12-15
Abstract: 1378988 Pulse radar HUGHES AIRCRAFT CO 15 Dec 1972 58128/72 Heading H4D In a pulse radar system, circuitry is provided for processing either non-MTI signals in the absence of clutter, or MTI signals if clutter is present, the target detection sensitivity of the circuitry processing the MTI signals being a function of the number of targets detected in a given time period to prevent saturation of a data channel. A radar transmitter/receiver 13 is controlled by pulses from circuit 11 and receiver 13 provides azimuth and range count signals. Normal video signals are mixed in device 19 and then passed to quantizer 23 where they are converted to a four-bit word corresponding to their amplitude. The MTI signals are passed to a quantizer 25 performing a similar function. A device 33 determines from the pattern of bits received whether or not clutter is present. If not, the normal video is applied via selector 31 to device 15 which indicates that a target has been detected, its echo strength, and whether or not the target echo comes from device 23 or 25 thereby indicating if clutter is present or not. The signal is applied to an output device 35 and finally to a storage device 29 which stores a signal everytime a target is detected. If device 33 detects clutter the MTI signal is passed by selector 31 to the device 15 rather than the normal video. Again, the target information is passed to device 35, 29. Detector 27 determines whether the signal being processed is above the highest average background clutter level determined by sampling the MTI signals in range bin intervals around the range bin interval corresponding to the signal being processed. If it is above this the target signal is valid and is subsequently passed for processing. The sensitivity of device 27 is controlled by device 29 via leads ABCD. For a small number of target bits stored in device 29 the sensitivity of device 27 is at a high level so that target amplitudes a predetermined amount greater than the background clutter is valid. For a large number of stored target bits the sensitivity of device 27 is at a lower level so that only high amplitude targets are valid. In this way, the number of target bits processed in high target density areas is reduced, i.e. areas where clutter is likely. In addition, the target information rate passed to a subsequent data channel is reduced thereby reducing the possibility of channel saturation. A generator 17 is provided to produce test signals which are injected into the system during periods of the radar operating time allocated for such purpose. Detailed circuitry of devices 17, 37, 31, and 29 is given.
