Title: Improvements in and relating to electron discharge devices
IPC: H01J29/88
Filed: 1935-10-09
Abstract: In an electron-discharge device, an electrode is coated with a substantially non-reflecting layer of a metallic salt insoluble in water, prepared by acting upon a solution containing the metallic radicle of the salt with a solution which evolves the acid radicle. For example, an aqueous solution of a silver or lead salt, such as the nitrate or acetate, may be acted on by an alkaline solution of thiocarbamide or thiourea to produce silver or lead sulphide.  The electrode may be a silver coating on glass. According to the Provisional Specification the coating may be prepared by acting on a silver layer with an alkaline solution of thicoarbamide, which converts the layer superficially into silver sulphide.
Patent GB-1464539-A (GB)
IPC: H04Q3/00
Filed: 1974-06-10
Abstract: 1464539 Automatic exchange systems PLESSEY CO Ltd 10 June 1974 [12 June 1973] 27945/73 Heading H4K  Malicious calls are traced with the aid of a special relay set MCRG inserted on the line side of the line circuit SLCB of a subscriber subject to such calls. Display of the calling number is effected (at a remote operator's position R0) when the called subscriber dials a predetermined digit. If the caller is not attached to the called party's exchange, the MCRG is conditioned, by the last incoming digit remaining on line to request identification immediately from the calling exchange. (The identity is stored pending dialling of the predetermined digit.) The exchange is a local/transit exchange of R2, 5005 cross-bar type c.f. Specification 1,333,791. A local call is set up from Sub A to Sub B in the normal way but upon reaching Sub B's line circuit a special class of service signal is reverted to the router control RC. Consequently in the local transmisssion relay group LTRG which is being used for the call, a so-called "bridge-in" and "no-ringing" condition is set up. The former includes the function of switching through the P wire so that holding is transferred forward to the malicious call relay group MCRG whilst the latter condition puts the supply of ringing current and ringing tone under control of the MRCG. If the call is malicious, Sub B dials a digit which is effective to sustain the hold condition of the P wire following calling party release. Additionally a malicious calls register MCREG and a general purpose outgoing multifrequency control unit OGMFCU are seized. The OGMFCU enables a calling line identifier CLI which obtains the calling line identity by pulsing over the P wire. When the identity has been registered, it is forwarded in MF format to an MF receiver ICMFE associated with the remote operator's position and is there displayed. An incoming call on ICJ is set up as usual but in view of Sub B's class of service the control RC applies a "digit-on-line" condition to the relevant incoming transmission relay groups ICTRG. This causes the last digit to be forwarded to the MCRG which thereupon seizes an MCREG and an incoming MF control unit ICMFCU. The latter interacts with CLI equipment at the calling exchange so as to obtain the caller's number which is stored in the MCREG. If the call is malicious Sub B dials a digit which causes read-out of the stored identity to the operator as described above.

Abstract: 422,725. Photometric apparatus. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, CAMPBELL, N. R., and WINCH, G. T., c/o General Electric Co., Wembley, Middlesex. Oct. 16, 1933, Nos. 28637/33 and 8977 /34. [Class 97 (i)] [See also Group XXXVI] The photo-electric current in a photo-electric device of the rectifier type, consisting essentially of a layer of semi-conductor between metal electrodes and generating a photo-electric current when light is incident upon it, is measured by bringing both terminals of the device to the same potential by means of an external source of E.M.F. In the arrangement shown in Fig. 1, a galvanometer G is connected across the terminals of the photo-electric cell C, and the measuring instrument M, e.g. a microammeter, is connected to a tapping on a potentiometer R fed by a battery E. When light is incident upon the cell, the potentiometer tapping is adjusted until no current flows through G ; there is then no potential difference across the cell and the instrument M measures the photo-electric current. In the arrangement shown in Fig. 2, the potentiometer comprises resistances 5, 6 of different resistancetemperature coefficients, and the terminals of the cell 1 are connected to tappings 7, 8 on the resistance 5, the lead to the tapping 7 including a variable resistance 9. When no current flows through a galvanometer 2 connected across the terminal of the cell 1, the position of the tappings on the resistance 5 gives a measure of the photo-electric current. By suitable choice of the magnitude and temperature coefficients of the resistances 5, 6, variations in photo-electric current with temperature can be compensated, so that the photo-electric current is directly proportional to the illumination and the potentiometer 5 can be calibrated directly in foot-candles. The range of the calibration can be changed by varying the resistance 9. The arrangements are particularly suitable for portable photometers.
