Abstract: 1462544 Measuring chemical concentration COMBUSTION ENG Inc 14 March 1974 [18 March 1974] 10776/75 Heading G1A A chemical shim (soluble neutron absorber) concentration analyzer comprises a container 34, neutron source 50, a detector e.g. 56, to detect neutrons unabsorbed by the liquid sample and generate a signal related to chemical shim concentration, means 57 for generating a liquid sample temperature signal, and means 67, Fig. 3 for generating a compensation signal from the said temperature signal and using it to correct the signal related to chemical shim concentration for temperature effects. In the embodiment of Fig. 2 coolant-moderator containing boric acid is withdrawn from the primary loop (16), Fig. 1 (not shown) of a pressurized water nuclear reactor by conduit 12 and returned by conduit 14. Four detectors 56, 58, 60 and 62 are symmetrically disposed about a standard one Curie plutonium beryllium neutron source and the count rate signals from the detectors are combined and amplified by preamplifier 84. The resultant signal passes into the signal conditioning unit 67 where it is transformed into a proportional chemical shim concentration (PPM) signal and added by operational amplifier 88 to the temperature compensation signal. The latter is derived as follows. The temperature signal T from thermocouple or thermistor 57 via amplifier 63 is compared with a calibration temperature signal by  operational amplifier 22. A resultant temperature difference signal K 1 #T is fed to operational amplifier 86 and is also multiplied by the PPM signal by multiplier 24, the output of which K 2 #T(PPM) is also fed to the amplifier 86. Amplifier 86 adds the two inputs to give the said temperature compensation signal. K 1  and K 2  are gain constants for the particular shim and analyzer used, and for the arrangement described are 0.54 PPM/F and 5 x 10<SP>-4</SP> PPM/F.PPM respectively. The corrected concentration signal from unit 18 may be fed to a regulatory system (28) where it is compared with other reactivity parameters to trigger a chemical shim supply (30) to adjust the chemical shim concentration in the primary coolantmoderator loop (16).

Title: Improvements in or relating to electric motor controllers
IPC: H02P25/28
Filed: 1934-04-13
Abstract: 426,100. Control of two A.C. motors. IGRANIC ELECTRIC CO., Ltd., 147, Queen Victoria Street, London.-(Assignees of Russell, F. J.; North 12th Street, Milwaukee, Wisconsin, U.S.A.) April 13, 1934, No. 11183. Convention date, April 14, 1933. [Class 38 (iii)] Squirrel cage motors 1, 2 are so controlled by series reactors 9, 10, 11, having directcurrent controlling coils 14 that, upon initiation of plugging, the reactance of the reactors is high and is subsequently reduced automatically to control the plugging operation. Upon closure of one of the contactors 3, 4, the motors 1, 2 run in the corresponding direction, with the reactances 9, 10, 11 in their primary circuits at maximum value, the initial rush of current causes a relay 18 to operate to connect the control coils 14 of the reactances to a direct-current source, so that the value of the reactances is gradually reduced, and the motors accelerate. The consequent fall in motor current causes the relay 18 to disconnect the control coils 14 to increase the reactance, the relay 18 being designed and adjusted to delay the increase in reactance until the motors attain a speed such that the motor current is reduced to a value at which the voltage drop across the reactance is small. When " plugging " is initiated the reactance is high, but the increase of motor current causes the relay 18 to reconnect the control coils to decrease the reactance gradually. After the motors are decelerated and accelerated in the reverse direction the relay 18 again disconnects the control coils 14. The reactors are adjustable by a rheostat 19, and may be provided with means to adjust their time elements. The motors may have separate sets of reactances with a common control means for their controlling coils.

Title: Aerial
IPC: H01Q9/16
Filed: 1958-04-10
Abstract: 843,984. Aerials; R.F. couplings. DAY, A. E., and CRIGHTON-GOODMAN, G. April 8, 1959 [April 10, 1958], No. 11349/58. Class 40(7). An aerial unit comprises a pair of rigid elements 3 of equal length mounted on a common base I which carrys an impedance matching transformer having one of its windings connected between the supported ends of the elements 3 and the other winding connected to a feeder. The arrangement enables the aerial to be readily matched to its feeder and in the preferred embodiment the aerial is constructed so as to be capable of receiving signals in both the 41-68 megacycle band and in the 174-216 megacycle band. As shown the aerial elements 3 terminate in balls held in suitable housings 4 which contain springs so that the elements are retained in whatever position they are arranged. For storage purposes the aerial elements themselves may comprise a plurality of telescopic parts that can be shut up into a small compass. Alternatively the elements 3 could be formed from ribbons of springy steel, curved transversely so as to be self-supporting and capable of being coiled up on spools within the base after the fashion of known steel measuring tapes. Wires 6 are led from solder tags 7 on the element housings to the two ends of the primary winding 8 of the coupling transformer. This winding consists of ten turns on a former 9 which is a third of an inch in diameter and the secondary winding 11 is wrapped round it and comprises 2¢ turns. The ends of the secondary winding are connected to the co-axial feeder 12. The transformer is provided with an adjustable core comprising an iron-dust section 15 and a brass section 16. The core is mounted on a slider by means of rod 17 and the degree of insertion into the transformer is controlled manually by a knob 19 projecting through a slot 20 in the base 1. For operation in the lower frequency band the aerial operates effectively as a centre-fed half-wave dipole, the effective length being adjusted by movement of the core. In the higher frequency band the elements behave as separate half-wave aerials feeding into a common matching transformer whose impedance is too high for it to form an effective part of the aerial. The base 1 is attached to a plinth 2 containing a layer of foam plastic material 21. A keyhole slot for wall mounting may be incorporated.

Title: Chrominance-signal demodulating system
IPC: H04N11/14
Filed: 1957-04-08
Abstract: 815,680. Television. HAZELTINE COR PORATION. April 8, 1957 [May 7, 1956], No 11372/57. Class 40 (3). In a colour television receiver utilizing a chrominance sub-carrier modulated at different phases by two colour-difference signals, part of one side-band resulting from the modulation by one of the signals being suppressed, cross-talk and amplitude distortion, due to such side-band suppression, in the outputs of individual detectors which are employed to derive the two colour-difference signals from the modulated sub-carrier is minimized by suitably combining a portion of the output signals of each detector with the whole of the output signals of the other detector. The invention is concerned with a receiver utilizing a signal of the N.T.S.C. type and in one embodiment (Fig. 1) in which the detectors 24, 25 are employed to derive the I and Q colour-difference signals respectively crosstalk consisting of the high-frequency (0.5 to 1.5 Mc/s.) components of the output of the I detector which appear in the output of the Q detector due to such components being transmitted as a single side-band signal are neutralized by subtractively combining (in circuit 33) such components, derived by means of a circuit 30 which introduces a 90 degrees phaseshift, with the whole of the output signals of the Q detector 25. The output of the combining circuit 33 then consists of the Q colour-difference signal (the double side-band signal) extending over the range 0-0.5 Mc/s. Because of the single side-band transmission of the 0.5-1.5 Mc/s. components of the I signal such components appear in the output of the I detector 24 with half the amplitude of the 0-0.5 Mc/s. components and to remove the resulting distortion the former (0.5-1.5 Mc/s.) components which appear in the output of the Q detector (also at half amplitude) 25 are selected and phase shifted by 90 degrees in circuit 31 and additively combined in a circuit 32 with the whole of the output signals of the I detector 24. The output of circuit 32 thus consists of the I colour difference signal extending from 0-1.5 Mc/s. with constant maximum amplitude and this signal is combined in a matrix circuit 28 with the Q output of circuit 33 to produce the R-Y, B-Y and G-Y colour difference signals for application to the picture reproducing tube 20. The Specification includes a mathematical analysis of the process of synchronous detection and equations are derived showing the relationship between phases of the demodulating waves supplied to the detectors and the phase shift which the circuits 30, 31 must introduce to effect the necessary compensation in the combining circuits 32 and 33. The analysis shows that such compensation may be effected when signals other than the I and Q signals are detected by the detectors 24, 25 and in a second embodiment (Fig. 7, not shown), the operation of the invention when the detectors are operated to detect the B-Y and GY colour difference signals is described.
