Patent GB-940255-A (GB)
Title: Cycloaliphatic carboxylic acids and esters thereof
IPC: C11B9/00
Filed: 1962-01-05
Abstract: The invention comprises cyclododecane carboxylic acid, the cyclododec-1-ene carboxylic acid of melting point 121 DEG C., the cis and trans cyclododec-2-ene carboxylic acids and the esters of said acids.  Cyclododecane carboxylic acid is prepared by hydrogenating e.g. in the presence of Raney nickel as catalyst, one or more cyclododec-1-ene carboxylic acids and/or cyclododec-2-ene carboxylic acids.  The unsaturated acids are prepared by reacting the sodium derivative of cyclododecanone (formed by the action of sodamide in the presence of anhydrous diethyl ether on cyclododecanone) with ethyl carbonate to produce ethyl 2-oxo cyclododecane carboxylate, subjecting the product to treatment with an alkali metal borohydride in the presence of an alkali metal hydroxide, dehydrating the isomeric 2-hydroxy cyclododecane carboxylic acids thus obtained, e.g. by the use of a dehydration catalyst such as para-toluene sulphonic acid, and separating the cyclododecene carboxylic acids obtained. Dodecanolactam is formed by reacting cyclododecane carboxylic acid with a nitrosating agent, hydrolysing the product obtained and finally treating with a compound having an alkaline reaction, more especially an alkali metal carbonate.

Title: Improvements in electrical ignition systems for internal combustion engines
IPC: F02P3/01
Filed: 1942-01-16
Abstract: 587,437. Ignition systems. CALVERT, W. J. R., DEBENHAM, W. R., and JONES, F. L. Jan. 16, 1942, No. 642. [Class 7 (iv) ] A high-frequency ignition system consists of a high-frequency transformer P, S excited by means of a spark-gap G with a breakdown voltage between 1 and 5 kilovolts and operated either by means of an ignition coil supplied from an engine-driven generator or by means of a magneto M ; the product of the inductance (L) of the secondary circuit of the magneto or coil and the capacity (C) of the primary condenser of the H.F. transformer lies between 10 - and 8 Î 10<-8>, the resistance (R) of the secondary circuit of the magneto or coil is governed by the relation R # (C/L)<0.5, C lies between 2 Î 10<-><9> farad and 50 Î 10<-9> farad, and the resistance (R) is limited by the relation L/R<6t, where t is the minimum interval of open circuit of the contact-breaker B at the maximum engine speed. A resistance r in the sparking plug Z or in the connector or the lead hear the plug is governed by the relation f, r <10<4>, where f is the effective frequency of the E.M.F. applied to the plug. When an induction coil and generator are employed, the contact-breaker B is arranged between the primary of the coil and earth. In the preferred form, the natural frequency of the transformer primary P is approximately equal to that of the combination of secondary circuit inductance and capacity when the secondary circuit contains the sparkplug lead of greatest capacity ,and the coefficient of coupling of the transformer is between 0.5 and 0.84. The spark-gap G is of the kind described in Specification 582,932 and is filled with a gas, such as air or nitrogen, giving a breakdown potential between 0.75 and 1.3 times that given by air under similar conditions, and between 0.85 and 1.3 times that given by air at normal temperature and pressure. Two such systems may be combined to form a dual ignition system; both systems may be independent of a battery except during starting, or one system may be completely independent of a battery and the other supplied from a battery during starting and normal running. The generator employed is separate from the batterycharging generator and preferably of the construction described in Specification 505,660. One generator may supply both ignition systems during normal running, in conjunction with a hand-operated hold-on change-over switch as described in Specification 538,250.

Title: Improvements in and relating to frequency variation response network
IPC: H03D5/00
Filed: 1942-01-16
Abstract: 554,836. Frequency discrimination ; automatic frequency control. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 16, 1942, No. 660. Convention date, Jan. 17, 1941. [Class 38 (iv)] [Also in Groups XL and XXXVI] Deviations in the frequency of a carrier wave are indicated or measured by applying the carrier across one diagonal of a bridge circuit and connecting a circuit or crystal, resonant to a standard frequency, across the other diagonal ; the bridge arms are unbalanced, one pair being constituted by reactances, and the other by rectifiers, and the magnitude and polari y of the difference ot the rectified current is indicative of the frequency deviation. The circuit may be used as a demodulator of a frequency-modulated wave, or as an error detector for the regulation of the tuning of a radio transmitter or receiver, or for the measurement of frequency. The F.M. detector shown comprises an amplifier 10 feeding the carrier across a point between two condensers 14, 15, and an earth point connected to the cathodes of the rectifiers 16, 17. The condensers 14, 15 and the rectifiers 16, 17, form the arms of a bridge circuit, the horizontal diagonal of which includes the circuit 13 resonating at the standard frequency. The carrier is thus applied directly to the rectifiers in phase agreement, and owing to the unbalance of the bridge the circuit 13 is energized and applies voltages in phase opposition to the rectifiers, these voltages being in quadrature with those directly applied when there is no frequency deviation, but varying in either sense from the quadrature relation when the frequency differs from the standard. Voltages taken at lead 23 across the joint lead resistances 18, 19, are a measure of the frequency deviation. The bridge may be unbalanced by connecting a variable inductance 22 across one or both rectifiers, or by using condensers 14, 15 of unequal capacity, or by using diodes of unequal size. The input from valve 10 may be to a point on the inductance of the circuit 13 displaced from the mid-position. Amplitude modulation may be detected by a rectifier 27 associated with a tuned circuit 24, 25, 26 coupled to the circuit 13. The Specification describes a circuit for the control of the frequency of a radio transmitter, Fig. 2 (not shown) in which a piezo-electric crystal replaces the tuned circuit 13 and in which the voltage on the lead 23 is smoothed out and used to correct the frequency of the transmitter by applying it to the grid of a reactance valve associated with the oscillation generator. The reactance valve may also be used for applying frequency modulation to the generator from a microphone or other signal source. The piezo-electric crystal may be operated in the range in which it exhibits either series-resonant or parallel-resonant characteristics ; or two crystals operating respectively in these ranges may be used in parallel; or a parallel resonant crystal may be connected in parallel with a series-resonant circuit.

Abstract: 195,763. Stone & Co., Ltd., J., and Adams, C. E. Jan. 9, 1922. Electromagnetic switches.-In electric lighting installations for trains &c. comprising a variablespeed generator, two batteries, an electromagnetic battery change-over switch and an electromagnetic cut-in switch, the cut-in switch cannot operate till its air gap has been reduced by the operation of the change-over switch: The coil a of the change-over switch is connected across the dynamo, and as the speed of the latter increases, the core c is sucked up at a voltage less than the cut-in voltage. The core c in rising operates the switch lever h and also, by means of an abutment v<2>, strikes against and lifts the core p of the cut-in solenoid o, reducing the air gap in the latter. Later, the cut-in speed is reached and the core p is sucked up completely, closing the circuit at main and auxiliary contacts q. r, and also operating a lamp resistance switch x. The operation of the switch-lever h is effected by a pin e<1> on a link e engaging a slot f in a member g carried by the lever h. As the core c rises, the pin e<1> is guided by a spring g<1> into a recess f<1>, and then pulls over the lever h. When the core c falls, the pin e' will slide to the righthand side of the slot f ready on the next rise of the core c to move the lever h back again.
