Title: Improvements relating to television transmitting apparatus
Inventor: JAMES IVANHOE JOHN PENFOUND
IPC: H04N5/18
Filed: 1951-03-07
Abstract: 696,386. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Feb. 25, 1952 [March 7, 1951], No. 5476/51. Class 40 (iii). In television transmitting apparatus employing a pick-up tube, it is arranged that the scanning beam in the tube is extinguished before each return stroke of the line-scanning waveform is initiated so that a period of "no signal" occurs without interference from the line return stroke, and means are provided for utilizing the interval of " no-signal " for direct-current reinsertion. The invention is applicable to pick-up tubes such, for example, as those operating with cathode potential stabilization in which, when the beam is extinguished, the signal output in the absence of spurious signals represents or bears a fixed relationship to black. In Fig. 1, the output from pick-up tube 1 is derived from impedance 4 and applied through amplifiers 5, 6, clipping circuit 7 and mixer 8. Timing pulses at line frequency are derived by circuits 11-15 controlled by master oscillator 16, Fig. 2, showing the relative timing of the pulses. Similar circuits (not shown) are provided for the frame timing. Black-out pulse 18 from circuit 11 suppresses the tube beam and is timed to occur 3 Á sec. before line timing pulse 19 from circuit 12 which is applied to the line scan generator 17 to initiate the return stroke. The 3 Á sec. " no-signal " interval is accordingly kept free from spurious signals due to the flyback and provides a reference representing absolute black. During the interval a D.C. re-inserting circuit 10 is rendered operative by clamping pulses 20 timed to occur wholly within the interval. Circuit 14 provides a suppression pulse 21 which displaces the signals in the clipping circuit 7 so that spurious signals introduced by the flyback are removed by clipping. Circuit 15 provides synchronizing impulses 22 which are added to the video signal in mixer 8. It is stated that the line timing pulses may be employed as subsidiary pulses to suppress spurious signals. Specification 449,242 is referred to.

Title: Production of bis-(dimethylamino)-chlorophosphine oxide
Inventor: LESTER PATRICK
IPC: C07F9/26
Filed: 1952-03-04
Abstract: In a process for the manufacture of bis-(dimethylamino)-chloro-phosphine oxide, phosphorus oxychloride is heated with tris-(dimethylamino)-phosphine oxide, the reactants being employed in the proportion of at least two mol. of tris-(dimethylamino)-phosphine oxide per mol. of phosphorus oxychloride.  An excess of the triamide starting material is desirable and may be sufficient to form a solvent for the diamide in subsequent reactions, e.g. in the conversion of the diamide into the corresponding fluoro compound.  Addition products may be formed in the first stages of the reaction and the formation of a monoamide may take place if an excess of phosphorus oxychloride is present.  The triamide starting material can be prepared by reacting phosphorus oxychloride with diphenylamine in the presence of a solvent and a suitable base. An example is furnished.  Specifications 631,549 and 652,981 are referred to.
