Abstract: A process for separating an aqueous emulsion including an aqueous phase and an non-aqueous phase into separated aqueous and non-aqueous phases, to provide a recovered non-aqueous phase, and to provide a recovered aqueous phase containing an acceptable level of the non-aqueous phase. In the process, at least one body, and preferably two or more bodies, of polymeric material with a high surface area, typically a foam material or polymer chips, is used in a horizontal flow treatment system to break the emulsion and thus provide both the aqueous and non-aqueous phases as two separate flows. A wide range of polymers can be used in the system as the polymeric material including polyurethane, polypropylene, polystyrene, polyester, and polyethylene. If a very low level of non-aqueous phase in the effluent is required, for example to meet potable water standards, then a Kozlowski polyurethane, as described in U.S. Pat. No. 5,239,040, is preferred as the last Polymeric material body.

Title: Automatic steering equipments for vessels
IPC: G05D1/02
Filed: 1964-05-23
Abstract: A magnetic compass is associated with a compass cord carrying two movable electrodes, and four fixed electrodes whereby an A.C. field generated by energization of the movable electrodes produces A.C. potentials at the fixed electrodes whose amplitudes provide an indication of the craft heading. As shown (Fig. 1), a compass cord 5 is carried by a float 6, pivoted at 9, the lower portion of the float being part-spherical and part-conical, with an annular magnetic compass 8 in the space between these parts. A conical supporting member 12, symmetrically located under the float 6, has two annular electrodes 13, 14 on its surface, facing two similar electrodes 17, 18 on the surface of the conical part of float 6, which are connected to strip electrodes 19, 20 mounted on the spherical part of float 6. Four fixed electrodes 26, 27, 28, 29 are mounted in the compass bowl symmetrically located with respect to the float 6. Electrodes 13, 14 are energized with A.C. from a transformer 31, the voltage being electrostatically transferred to electrodes 17, 18 and then to electrodes 19, 20 producing an electric field in the compass liquid which is sensed by fixed electrodes 26, 27, 28, 29 whose potentials are indicative of the relative positions of the compass card 5 and the fixed casing 1. These potentials are amplified (Fig. 4) and fed to a crossed coil instrument 52 to repeat the compass reading or to a circular potentiometer 34 having diametrically opposite sliders 40, 41, giving a signal indicative of the actual heading of the craft relative to a desired heading, which may be fed to an autopilot device via lead 43. The numbers of electrodes used may be other than two for feeding the A.C. voltage, and four for picking up the heading signal.

Title: An annular fuel element for a nuclear reactor
IPC: G21C3/08
Filed: 1967-05-27
Abstract: An annular fuel element for a natural uranium reactor cooled by circulation of CO 2 gas in the same direction inside and outside the element comprises a tubular slug of nuclear fuel covered with external and internal cladding, both of which have fins arranged in chevrons and are connected by annular plugs, the external cladding and plugs being made from a Mg-based alloy and the internal cladding from Zr or a Zr-based alloy having a higher hot strength than the Mg alloy. Suitable Zr alloys are Zircaloy ATR (containing, by wt., 0À5% Cu and 0À5% Mo), Zircaloy AJR (containing, by wt., 1% Cu and 1À5% Mo) and Zircaloy-2 (containing, by wt., 1À5% Sn and small additions of Ni, Cr and Fe). The fins on the internal cladding are preferably shallower than those on the external cladding. The external cladding may also have longitudinal partitions for centering the fuel element in a coolant duct. An annular disc of thermally insulating material resistant to creep when hot (e.g. a ceramic) is interposed between each plug and the fuel. The fuel is covered with the cladding members which are then forced against the fuel by any suitable method, e.g. hydraulic cladding after temporary plugging. The permanent plugs are then attached. The cladding members are preferably anchored on circular grooves in the fuel to prevent a ratchet effect during thermal cycling. The plugs are joined to the external cladding by arc-welding in an argon atmosphere or by electron beam welding and to the internal cladding by a process similar to that described in Specification 1,099,025.

Patent ES-364522-A1 (ES)
Title: Automatic degaussing circuit for tv having half-wave voltage doubler power supply
IPC: H04N9/29
Filed: 1969-03-08
Abstract: In an arrangement for degaussing television apparatus, specifically the shadow-mask tube of a colour television receiver, the receiver employing a cascaded voltage doubler type of rectifier circuit for producing the normal D.C. operating voltages, the capacitor portion of the first stage is formed as two parallel paths comprising capacitors 31, 41 (Fig. 1) each in series with a thermistor 33, 43 one of which, specifically 43, is shunted by the series arrangement of a voltage dependent resistor (VDR) 51 and a de-gaussing coil 53. The operation is as follows. On switching-on, initially, A.C., one pole of which is grounded, is supplied via switch 13 to, inter-alia, the rectifier circuit and due to the high resistance of the thermistors when cold the major part of the charging current flows in the shunt path including the coil 53. As the thermistors heat up the falling resistance results in a reduction of the current flow in the coil 53 and a reduction in the voltage applied to the VDR 51 so that the resistance of the latter increases. The A.C. flowing in coil 53 is thus gradually reduced to zero to effect the required de-gaussing at which point the resistance of the series arrangement of the coil 53 and the VDR 51 has a high value so that negligible current flows therethrough and the charging current now flows through thermistor 43 (and through thermistor 33 which now has a low resistance). By dividing the capacitor portion of the first stage of the rectifier into two parallel paths the capacitor operative in the de-gaussing circuit, capacitor 41, may be given a capacitance value of the same order as that of the second stage capacitor 73 so that current pulses of the same magnitude flow during each half-cycle of the A.C. input. This arrangement avoids undesirable spot shift effects which the use of an asymmetrical charging current would give rise to whilst allowing the use of capacitance values resulting in maximum efficiency and economy in the design of the voltage doubler rectifier circuit. The two thermistors should be in close thermal contact and may be replaced by a three-terminal device containing two thermistors (Fig. 2, not shown). The filament transformer 15, which has a tap TH for use under condition of high line voltage so that correct filament voltages are available, supplies the filament of the picture tube 19 via the secondary winding TS and filaments of the damper tube in the horizontal deflection circuit and the series string connected filaments of the remaining tubes via taps, DF and FS respectively.
