Abstract: 1430986 Oil recovery VICKERS Ltd 10 May 1974 [15 May 1973] 23170/73 Heading B7A [Also in Division El] Oil from an underwater leak, e.g. a damaged well head is entrapped by the inverted conical base 4a of a buoyant structure and passes up through duet 12 in a vertical column 2 before being pumped into a tanker or like vessel. The structure is towed to the polluted area with its buoyant superstructure 3 adjacent its base buoyancy chamber 1, as shown in pecked outline in Fig. 1, and in this condition floats at waterline 19. After being centred over the leakage, sea water valves are opened to admit water to ballast tanks in the base chamber 1 so as to sink the column 2 and bring the superstructure 3 to the head of the column, additional ballast also being introduced into a tank 14 at the base of the column. The superstructure 3 is connected to the column head 9 by way of an annular collar 18 and then the tank 14 is emptied to raise the superstructure above a new waterline 21. Sea water is extracted by a pump (not shown) from the upper end of the duct 12 so that oil replaces it by passing upwards from the base 4a. When all the sea water has been expelled pumping is interrupted to connect up hoses to a tanker or the like moored alongside and then restarted to load the tanker. Recovered oil may also be stored in the tanks of ballast chamber 1. The central duct section has an upward extension 22 at the column head 9 which extension terminates at 24 well clear of the superstructure 3 for venting unwanted gases.

Title: Improved pneumatic selector valve for a change-speed gear
IPC: F16H61/02
Filed: 1959-07-07
Abstract: 915,024. Change-speed control. TATRA, NARODNI PODNIK. July 7, 1959 [July 10, 1958], No. 23392/59. Class 80 (2). In a control for a rear mounted, two-stage, six forward speeds and one reverse change-speed gear for motor vehicles, gear engaging and changing compressed air servomotors 55, 56, 57 and 66 are energized and vented, through a steering column mounted manual selector valve unit having fast on its control spindle 4 an actuating assembly comprising a profile member 6 actuating a valve 13 connected to cylinders 55, 56, 57 for neutralizing primary stage and reverse; a cam 7 actuating valves 75, 12 connected to the cylinder 66 for secondary stage gear change; and a profile member 8 actuating valves 10 and 77, 76, and 11 connected to cylinders 55, 57 and 56, respectively, for primary stage gear and reverse engagement. The valves are located in a housing 2, the chamber 9 of which is connected to a compressed air source through a port 17 (Fig. 5) and in a housing cover 3 which guides the control spindle 4 in a journal sealed at 19. In each valve, lift of a pin 15 against a spring 32 moves a piston assembly 25 for cylinder pressurizing via a groove in a rubber sealed seating 27 and a line 23. Spring return of the piston assembly 25 permits cylinder venting via the line 23, a passage 35 and a port 24, which latter is blocked by engagement of a member 31 of the piston assembly 25 with a rubber seating 30 when the pin 15 is lifted. This valve arrangement ensures gentle servomotor energization and venting. The selector valve unit is mounted on the steering-box and the control-spindle 4 is actuated through a universal-jointed tube 52 by a hand lever 44 in a steering column mounted gate 42. A spring 68 biases the control spindle assembly downwards, in which position the lever 44 is urged upwards to engage gate notches I-VI, N and Z (reverse). In operation, the lever 44 is depressed for disengagement from the notches, thereby raising the member 6 to actuate the valve 13 for neutralizing, and is then rotated parallel with the steering-wheel 39 to select the gear required. On release of the lever a projection of the downwardly-moved member 8 actuates one of the valves 10, 77, 76 for the selected primary stage gear engagement or the valve 11 for reverse. During rotation of the lever 44 between third and fourth gear positions the cam 7 selectively actuates the valves 75 and 12 for secondary stage gear change between reduction (for Reverse, 1st, 2nd and 3rd) and 1/1 (for 4th, 5th and 6th). The member 8 has itself a neutral position corresponding to the gate notch N between I and Z. Servomotor impact noise may be obviated by providing vulcanized rubber damping discs on the piston ends.

Title: Metallurgical melting furnace or hot metal mixer with electromagnetic stirring
IPC: F27D27/00
Filed: 1953-08-26
Abstract: 725,518. Electric furnace with electromagnetic stirring. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Aug. 26, 1953 [Sept. 17, 1952], No. 23526/53. Class 39 (3). An electric metallurgical melting furnace, arc furnace or hot metal mixer has one or more longitudinal multi-phase stirring coils 4 below the bottom of the furnace and fed with a very low frequency current, at least one of the stirrers 4 being arranged with its vertical symmetrical plane on one side of the axis or one of the planes of symmetry of the furnace. The coils 4 have magnetic cores. Each stirrer is arranged with its vertical symmetrical plane parallel with the long axis of the furnace and where several stirrers are used they are arranged in this manner on the same or opposite sides of the long axis of the furnace. The stirrers may be arranged in one row or in two parallel rows on opposite sides of said long axis. Several stirrers may be arranged parallel with each other perpendicular to the long axis of the furnace. Each stirrer is movable perpen-' dicular to its vertical symmetrical plane. The phase sequence of the stirrers is reversible and the phase sequence of each stirrer may be changed independently. In the open hearth melting furnace shown in Fig. 4a, the arows denote surface movement of the melt and B denotes the mixing zone where the melt rises to the surface. The phase sequences may be arranged to give a surface movement directing the slag to a discharge opening 2. Thus a single stirrer may be arranged symmetrically below the bottom to obtain better mixing at the bottom of the furnace and then shifted to one side to aid deslagging..

Abstract: 950,198. Determining relative quantities of fluid mixture constituents. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. June 20, 1961 [July 8, 1960], No. 24007/60. Heading G1N. [Also in Division G3] In an arrangement for controlling the admission of acid and uranium to maintain optimum conditions for solvent extraction from an acid solution of a uranium salt the electrical conductivity and the specific gravity are measured in a manner to produce electrical signals, both signals are applied to each of two resolver circuits including components of experimentally determined values to produce signals indicative of the acidity of the solution and of the uranium concentration, and the respective signals are applied each through a recorder controller to control valves in nitric acid and uranyl nitrate supply lines feeding the vessel containing the solution. Conductivity is measured by two side by side wound toroids T 1 , T 2 , Figs. 1 and 2, which are mounted in an insulated block 10 and coupled by a loop 2 of solution. Winding 3 of transformer T 1  is energized by an oscillator 4 having a frequency of 10 000 cycles and additional windings on the transformer are connected with a resistor R in a circuit 9 to produce a null output from transformer 2 for a predetermined conductivity of solution. The arrangement is self-balancing resistor R being adjusted by a motor 8 in response to an error signal detected in a phase sensitive detector 6. An output signal may be developed by a mechanically coupled wiper on a potentiometer connected across a voltage source. A temperature sensitive resistor immersed in the vessel may be connected in a network 9 to provide temperature compensation and the oscillator supply may be modulated at 50 cycles. A stainless steel float 21, Fig. 5, responsive to changes in S. G. tilts a weighbeam 22 about its pivot to change the capacity of a plate condenser 25 and insert a moving coil in a magnet 24. The change in capacity changes the output of an oscillator 27 to provide a signal to coil 23 whereby the beam is restored to its original position and the current in the coil provides an indication of specific gravity. A zero setting potential can be introduced.
