Patent GB-942545-A (GB)
Title: Improvements relating to polymeric cyanogen halides
Filed: 1960-02-05
Abstract: Tetrameric cyanogen halide, e.g. (CNCl)4, is prepared together with the trimeric form by the polymerisation of a monomeric cyanogen halide in the presence of a hydrogen halide and an amide of a secondary amine with a fatty acid, having 1 to 4 C atoms e.g. dimethyl formamide. A halogenated hydrocarbon, e.g. chloroform, methylene chloride, dichloro-ethylene, tetrachloroethylene, chloro-benzene, dichloro-benzenes, chloro - toluenes, trichloro - benzenes, chloro-naphthalenes, fluoroform, and alkanes containing fluorine and chlorine, can be used as a diluent in the reaction. The diluent may be omitted when the reaction is performed in a closed vessel with liquid reactants. The starting material may be cyanogen chloride or a mixture of cyanogen chloride and cyanogen bromide; with the latter, a product containing both chlorine and bromine is produced. Alternatively bromine can be introduced into the molecule by using hydrogen bromide instead of hydrogen chloride in the polymerisation of cyanogen chloride.  After distilling off any diluents, the tetramer is obtained by extraction with liquid, saturated, aliphatic or alicyclic hydrocarbons e.g. petroleum ether, filtering off the cyanuric chloride and distilling the filtrate. Otherwise, the cyanuric chloride can be removed by sublimation. Tetramers containing fluorine are obtained by reacting the tetrameric chloride with potassium fluoride.

Title: Improvements in or relating to dead-time loss compensating circuits
Inventor: BRYANT JACK
IPC: G01T1/18
Filed: 1957-02-06
Abstract: 821,162. Counting-apparatus. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Jan. 28, 1958 (Feb. 6, 1957], No. 4154/57. Class 106 (1). A dead-time loss compensating circuit for use with a detector which produces an electrical pulse for each detected event of a series but which may leave certain events undetected due to a dead-time following each detected event, has means for generating a second series of pulses whereof each is delayed by a fixed amount from each pulse corresponding to an event detected by the detector, gate means for accepting those pulses in said second series occurring substantially during dead-time periods following each detected event and means whereby the accepted pulses of said second series may be added to the pulses corresponding to detected events, thereby providing an estimate of the total number of detected and undetected events in the series. A detector, such as a Geiger-Muller tube adapted to detect events of a series of events randomly distributed in time, misses some events due to the " deadtime " following each detected event. If the events of a second series of events having the same mean frequency as the first series which occur in dead-time periods of the detector are counted, then an estimate of the number of lost events is obtained. The second series may be derived by delaying the first series. As shown, Fig. 1, negative input pulses from a detector are applied via a terminal T1 to a quenching circuit comprising pentodes V1, V2, each pulse cutting off the normally-conducting tube V2 for a period depending on the setting of the variable resistor RV1; the resulting rectangular waveforms, Fig. 3, are differentiated at C5, R11, the negative differentiated pulses triggering a flip-flop V4 to produce positive rectangular pulses at its left-hand anode, which pulses are differentiated at C7, R22, the negative pulses (" delayed pulses " in Fig. 3) being fed to the right-hand grid of a doubletriode gate V6, this grid also being fed with negative pulses derived by differentiation of the front edge of the quenching waveform by a condenser C2 and resistor R27. The gate V6 is opened by application of the quenching waveform slightly lengthened by a resistor R23 and condenser C10 to the left-hand grid of the valve V6 which is thereby cut-off to enable it to produce under the action of pulses applied to its right-hand grid positive, pulses to the output terminal T3 which is connected to a rate-meter or scaler. Thus the output at T3 consists of pulses corresponding to the input pulses at T1 together with those of the delayed pulses which occur during the periods when the gate V6 is open, i.e. slightly extended dead-time periods, the extension being provided to compensate for the input pulses being less than the true number of events by those lost in the dead-time periods. A second-order correction may be obtained by deriving a second delayed series from the series of correction pulses.

Abstract: 577,619. Automatic regulation. BRITISH THOMSON-HOUSTON CO., Ltd. March 9, 1944, No. 4405. Convention date, March 13, 1943. [Class 38 (iv)] In a static automatic voltage regulator, Fig. 1 an unsaturated reactor 9 and a saturated reactor 1( shunted by a capacitor 8 are in series across an A.C. input 5, 6 and a sub stantially constant voltage output 12 is obtained be tween the junction of the reactors 11, and a point 4 intermediate in potentia between the input ter minals, the normal operating range of the parallel reactor and capacitor, having a resultant capacitive reactance, being between resonance and the knee of the saturation curve of the reactor. The tapping 4 is on an auto-transformer 1 the ratio of which may be suited to the input voltage by adjustment of input tap 3. The output voltage 12 remains substantially constant under normal variations of input voltage and output current. The provision in series with the output of an unsaturated reactor 14 and a capacitor 15, resonant at the minimum input frequency, renders the output voltage 13 independent of normal variations of input frequency and tends to suppress harmonics. The connection of the capacitor across a secondary winding of the saturated reactor which is then in the form of an auto-transformer or two-winding transformer is referred to. Vector diagrams are given and a suitable saturable reactor with a reduced section where the winding surrounds the core is described.
