Title: Electric Analogue Angular Rate Deriving Circuit
IPC: G08C19/48
Filed: 1968-01-15
Abstract: 1,168,955. Rate derivative circuit. COLLINS RADIO CO. 15 Jan., 1968 [21 June, 1967], No. 2199/68. Heading G4G. In apparatus deriving a signal proportional to the time derivative of a variable # defined by modulated carrier signals of amplitudes proportional to sin # and cos #, signals are generated proportioned to the time derivatives of the signals, and the derivative of one is multiplied by the other and vice versa; the product being subtractively combined to produce the required output signal. A three wire synchro amplitude modulated input signal 10 over lines X, Y, Z is converted in a Scott T transformer 11 to quadrature signals proportioned to sin # and cos #, which are phase detected against a reference carrier at 13, 24; and lowpass filtered at 16, 26 to corresponding D.C. signals which are differentiated in highpass filters 18, 28, remodulated at 19, 29 with a reference carrier and applied to multipliers 21, 61 together with D.C. signals from the lowpass filter of the opposite channel. The multiplier outputs are subtractively combined at 33 to produce a modulated carrier signal at output 35 whose amplitude is shown by mathematics to represent d#/dt. The input signals may be directly derived from a twowire resolver output. The modulator carriers may be applied in antiphase and the multiplier outputs additively combined in a resistance or transformer network. The modulators may be eliminated by the use of D.C. modulators at 21, 22. Similarly, if D.C. input signals are used whose amplitudes represent sin #, cos #; the phase detectors 13, 24 may be eliminated. Solid state circuits may be employed, and the device is applicable to deriving rate of turn signals from a compass output.

Abstract: 1,189,943. Ejecting inflammable liquids from containers with foam. WALTER KIDDE CO. Ltd. 15 Jan., 1969 [15 Jan., 1968], No. 2209/68. Heading A5A. [Also in Division F1] Inflammable liquid, e.g. oil, is discharged from a container 1, e.g. a tanker, by injecting high expansion foam from a generator 6 and then pressurising the container to force the liquid through an outlet 5. Pressurising may be effected by continuously injecting foam, or by supplying pressurised air or gas, eg car- 'bon dioxide. The pressurised air or gas may be supplied by the foam generator, by shutting-off the supply of foaming agent after a blanket of foam has been formed on the surface of the liquid. Alternatively, pressurised air may be supplied by a fan to a separate inlet, Fig. 2 (not shown). The foam generator has a fan 11 supplying air, and a nozzle 8 supplying foaming agent. A throttle 13 in the air passage 10 regulates the air flow under the control of pressure sensors 14 and 15 upstream and downstream of a mesh 7, to maintain a constant pressure differential across mesh 7. Throttle 13 may be controlled electrically, pneumatically or hydraulically.

Abstract: 1,077,252. Reactors. ALFA-LAVAL A.B. Jan. 20, 1966 [Jan. 20, 1965], No. 2655/66. Heading G6C. A fuel assembly for a heterogeneous nuclear power reactor comprises a plurality of cylindrical fuel elements each rotatable about an axis which is eccentric to the central longitudinal axis of the element, whereby the spacing of the elements may be varied to effect long term control of the reactor output. In the embodiment described(Figs. 1a, 1b and 1c, not shown), a heavy water reactor comprises a pressure tank 23 in which are arranged nineteen fuel elements, twelve of which are outer elements 30, six are intermediate elements 31 and one is a central element 32. The fuel elements comprise fuel rod clusters 1, the fuel rods of which are suspended from a top piece 18 and are located at their lower ends by a bottom piece 19, being supported at several points along their length by screen plates 20 which permit the coolant water to flow at right angles to the fuel rods from an inner moderator space 25 to an outer moderator space 26. The top piece 18 is attached to the bottom piece 19 by means of an inner perforated tube 21 and an outer perforated tube 22. The fuel elements are lowered into the reactor through fuel ports 12 which are then closed by plugs 13 which house the operating devices 15 for the fuel elements. By rotating the devices 15 from outside the reactor tank, the central axes 2 of the fuel elements can be displaced towards or away from the centre of the reactor without necessitating any reduction of the reactor pressure or shutting down the reactor power output. The fuel elements 30 when in their extreme outer positions may be withdrawn through the ports 12. The central element 32 is not necessarily rotatable, while the intermediate elements 31 only need to have half the total radial displacement of the outer elements 30. Coolant water is led to the reactor through one or more inlets 24 and distributed to the elements 30 (31) from the top through openings 34, 35, 36 (38) and 4, and from the bottom, after having passed through the annular channel 28 (between the pressure tank 23 and a radiation shield 50) and the bottom distributer 7, through the connection 5. The water flows from the elements to the moderator space 26 and a reflector region 27, and from there to an outlet 29. The fuel elements when first introduced into the reactor are arranged closely in a small quantity of moderator water and as burn-up proceeds are rotated into an expanded pattern in a larger quantity of moderator water, an increasing number of neutrons thus being available for fission than for conversion.
