Abstract: 665,818. Discharge apparatus. STANDARD TELEPHONES & CABLES, Ltd. Sept. 26, 1947 [Oct. 3, 1946], No. 29545/46. Drawing to Specification. Class 39 (i). [Also in Groups XTX and XL (c). In a cold cathode gas-filled sequence electric discharge tube of the type described in Specification 639,827 the cathode of the last gap may have a larger area than the other cathodes so that when the tube is connected in a pulse circuit (see Group XL (c)) this gap passes a larger current than the others and assists the discharge of a condenser, connected across the last, gap, which discharges when the last gap fires, thus lowering the anode-to-cathode voltage below that required to maintain the discharges which are therefore extinguished to allow deionization of the tube between successive cycles of discharges of the gaps. Specification 665,817, [Group XIX], is also referred to.

Title: Improvements in or relating to telegraph systems
IPC: H04L7/033
Filed: 1938-10-13
Abstract: 506,573. Synchronous movements. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 13, 1938, -No. 29740. Convention date, Oct. 16, 1937. [Class 40 (iii)] Two electric charges are produced which are functions of the times between local circuit closures and the beginning and. end respectively of received telegraphic signals, and the difference between the two charges corrects departures from synchronism. The charges accumulate on condensers 5, 4, and control valves 7, 6 which are biassed to cut-off during the receipt of signals by current in a resistance 32 from a rectifier 3 which conducts during the receipt of keyed low-frequency signals. The local circuit closures by commutators 8, 9 occur simultaneously at the centre of each unit length of signal or at different times which are equally disposed on both sides of the centre. An impulse produced by the beginning of a signal causes a gas-discharge tube 26 to conduct and charge the condenser 5 until the tube is quenched by the commutator 9. When the commutator 8 closes the grid circuit of a gas-discharge tube 34 during a signal, an impulse from the tertiary winding 33 of a transformer 18 causes the tube to discharge the condenser 4 and thus quench the tube. The condenser is then charged until the end of the signal by current through a rectifier 2. During the subsequent space the valves 23, 24 pass currents, which depend on the charges on the respective condensers 4, 5, through a differential relay 22, which governs a motor 21 controlling a main driving motor 20. According to a modification, directcurrent signals are used, Fig. 3 (not shown).

Title: Improvements in or relating to a method of preparing isocyanic acid esters
IPC: C07C263/10
Filed: 1948-11-19
Abstract: Isocyanic acid ester is prepared by reacting in the vapour phase, a primary amine which is stable in the vapour phase and phosgene at a temperature within the range defined by the decomposition point of the corresponding carbamyl chloride and that temperature above which substantial decomposition of the ester occurs, and separating the resulting hydrogen chloride from the vaporous reaction product while the latter is maintained at a temperature within the above range, e.g. at a temperature to avoid substantial combination of the required ester with the hydrogen chloride.  The primary amine may be an aromatic, aliphatic, alicyclic, or heterocyclic amine or may be a primary amine containing mixed radicals of the above types.  The reactants may be employed in the theoretical proportions required to produce the isocyanate, or the phosgene/amine ratio may be at least 1 to 1 and may vary from 1.0 to 8.0 to 1 or from 1.4 to 2.8 to 1. Reaction temperatures may be within the range of 240 DEG  to 400 DEG C., or 260 DEG  to 300 DEG  C.  The separation of the desired ester from the vaporous mixture may be effected by physical and/or chemical means.  The esters containing at least 6 carbon atoms boil above the decomposition temperature of the corresponding carbamyl chloride and may be condensed and/or scrubbed from the vaporous reaction product, e.g. phenyl isocyanate can be condensed at a temperature above 125 DEG  C. or can be scrubbed out with an inert organic liquid at a temperature above 105 DEG  C.  The esters containing 2 to 5 carbon atoms, e.g. methyl isocyanate, boil in the range of or below the carbamyl chloride decomposition temperature and may be separated by scrubbing as above or by chemical reaction to remove hydrogen chloride, e.g. with calcium oxide or a tertiary amine such as pyridine or dimethyl aniline.  In the examples phenyl and methyl isocyanate are prepared.  Specification 656,726 is referred to.

Title: Improvements in or relating to single-sideband radio transmission systems
IPC: H04B1/68
Filed: 1955-10-21
Abstract: 797,696. Radio transmitting and receiving systems. PHILIPS ELECTRICAL INDUS. TRIES, Ltd. Oct. 21, 1955 [Oct. 25, 1954], No. 30157/55. Class 40 (5). In a single-sideband radio system the transmitter comprises a limiter following the sideband generator and a filter to suppress the distortion products of the limiter and the receiver comprises a limiter prior to the demodulator. In one embodiment of transmitter, speech signals from a source 22, Fig. 2a, are fed to the single-sideband modulator 25 through a filter 23 and pre-emphasis network 24. The modulator output is fed to the aerial 32 through a limiter 29, class C amplifier 30 and a singlesideband filter 31. The signal envelope from the single-sideband signal at the output of the modulator 25 is derived in an amplitude detector 33 and fed through a low-pass filter 34, having a cut-off frequency of 300 c/s. or less, to modulate a pilot frequency source 36 in the amplitude modulator 35 the output of which is fed through an amplifier 37 and filter 38 to the aerial 32. The pilot carrier frequency is either about 4 kc/s. different from the main carrier frequency or it may be nearly the same, or the same and derived from the carrier source 27 in the modulator 25. The envelope signal is unidirectional and is applied to the modulator 35 in such a sense that in the absence of speech signals the transmitted pilot signal has its maximum amplitude. The envelope amplitude modulation signal channel 33 ... 38 may be replaced by a frequency modulation channel, Fig. 2b (not shown). At the receiver, the aerial 43, Fig. 3a, feeds the demodulator 55 through amplifiers 44, 46, filter 45, limiter 47, amplitude modulator 52 and amplifier 53. The amplitude modulator 52 is fed with an envelope signal derived from an amplitude detector 50 fed from the amplifier 44 through a filter 48 passing a bandwidth of, for example, 100 to 500 c/s. The output of demodulator 55 is fed to the reproducer 59 through a filter 56, de-emphasis network 57 and amplifier 58. The amplitude modulator 52 produces a decreasing output with increase in envelope modulating voltage. When a frequency modulation envelope channel is used at the transmitter the envelope detector 50 is replaced by a limiter and frequency discriminator, Fig. 3b (not shown). The envelope signal channels at transmitter and receiver may be omitted and an unmodulated pilot frequency, loading the limiters during speech intervals, added to the signal by connecting the main carrier oscillator to the transmitter limiter through an adjustable attenuator, Figs. 1a and 1b (not shown).
