Abstract: 1298804 Pumps operating by electromagnetic interaction with fluids UNITED KINGDOM ATOMIC ENERGY AUTHORITY 19 May 1970 [30 May 1969] 27659/69 Heading H2A [Also in Division G6] An electromagnetic liquid metal pump comprises at least a pair of parallel ducts for liquid metal with a magnetic field applied transversely across the ducts such that by passing liquid metal through one of the ducts an EMF is generated in the liquid metal being passed through the duct. The EMF drives a current through the liquid metal in the second duct and an electromagnetic pumping action is thereby exerted on the liquid metal in the second duct. As shown in Fig. 2. the pump comprises a casing 21 divided into ducts 23, 24, 25 and 26 across which a magnetic field is set up by a permanent magnet (not shown). When liquid sodium is passed upwards through a pipe (not shown) in duct 23, it generates an EMF which in turn creates a downwards pumping action on lithium in pipes (not shown) in ducts 25, 26. A switching line 29 passing through the duct 24 comprises a closed loop with sodium in the bottom U of the lcop. The effect of this switching line 29 is that as the flow of sodium through the duct 23 is gradually increased there is initially no pumping action on the lithium in the ducts 25, 26. At first static sodium in the bottom U of the switching line 29 is drawn up into the duct 24 and at a threshold value of sodium flow rate through the duct 23 maximum pumping action is rapidly achieved on the lithium.

Filed: 1947-10-17
Abstract: 628,795. Piles. IONIDES, I. A. (Swann, P., and Sung, R. H. L. Oct. 17, 1947, No. 27845. [Class 68 (ii)] A pile comprises a concrete stem 1 containing a passage down which concrete is forced into a flexible bag 8 which extends laterally and forms a footing for the pile. By giving the canvas bag a suitable shape, the dimensions of the concrete foundation can be predetermined. The steel point 3, separable from the stem, has a central passage 5, communicating with openings 4, through which water may be forced to displace the material in which the pile is sunk. A tube 6 communicating with the passages 4, 5 has right-hand threads for its various joints and a quick pitch left-hand thread where it is screwed into the point 3. A clamp at the top of the tube 6 positions the tube relatively to the pile and maintains the point 3 in position. The flexible canvas bag 8 is contained in a metal housing 7 fixed to the body of the stem. The stem is provided with recesses 10 wherein slidable stop rods 9 with enlarged heads 11 at the upper ends, engaging the collars 17, are fixed at their lower ends in bushes 12 in the point 3. When the pile has been sunk to the required depth, water is forced through the tube 6 to form a cavity around the point. The water tube 6 is then unscrewed and partially withdrawn from the point which is prevented from turning by lugs 13 engaging recesses in the housing 7. Concrete is then pumped down the tube 6 and into the canvas bag 8 which expands to form a concrete-footing 14, the amount by which the stem and point are separated being limited by the enlarged heads 11. The water channels in the point portion are sealed by a soft plug 15 before insertion of the concrete.

Abstract: 660,208. Gyroscopic apparatus. BENDIX AVIATION CORPORATION. Oct. 29, 1948 [Jan. 30, 1948], No. 28149/48. Class 97 (iii). [Also in Group XXXV] In order to precess a gyroscope on departure of its spin axis from a reference position, the gyroscope carries an inductive element, a rolling mass adapted to vary the reluctance of the inductive element on such a departure of the spin axis so as to provide a displacement signal in the inductive element and means for precessing the gyroscope in response to the displacement signals. As shown, the erecting device 10 is mounted on the rotor casing 11 and comprises a steel ball 55 free to roll on a surface 26 under an inverted non-magnetic cup 56 located at the centre of cruciform laminated pole-pieces 42-45. Secondary coil windings 46-49, the diametrically opposite windings being oppositely wound and series connected, are wound about these pole-pieces and provide displacement signals according to the relative position of the ball 55 and its housing by the currents induced therein from the primary annular winding 30. The primary winding 30 is intermittently energized to allow decay of the magnetic field which would otherwise prevent the free rolling of the ball 55. The displacement signals induced in the windings 47-49 are amplified and applied to torque motors about the appropriate gyro axes. In another embodiment the steel ball is permitted to roll in an inclosure located beneath the poles of four vertically disposed pick-up windings.

Abstract: 1363663 Porosity measuring apparatus A T H A KHAZRAJI 23 Aug 1972 [17 June 1971] 28469/71 Heading G1S The apparatus comprises, a test chamber 6 adapted to contain a porous sample 8 held compressed by a screw down lid 4 and a pressure block 7, a valve 2 in a graduated tube 3, a further graduated tube 12 connected with a flexible pipe 11 and a mercury reservoir 13, a valve 14 connecting either to an air pump 15 or to atmosphere or a vacuum pump 17 via a further valve 16. In operation the valve 2 is opened to the atmosphere and air under pressure is provided via valve 14 to the mercury reservoir 13. This pressure drives the mercury from the reservoir into the test chamber 6 which is empty except for the block 7 and up the tube 3 to a predetermined mark. A volume reading is then taken on the graduated tube 12 near its bottom, the graduations reading zero at the reservoir and mounting as  the tube descends. This volume reading represents the bulk volume of the test chamber 6. The valves are now released to atmosphere and the sample 8 introduced into the chamber 6 which is tightly closed. The entry of the mercury into the chamber 6 and up to the mark on the tube 3 is repeated and another reading taken on the tube 12, this time near its top. The difference in the two readings gives the bulk volume of the test sample. Now the air pressure is increased to raise the mercury to a level just above the valve 2 which is then closed. Valve 14 is then released to atmosphere and valve 16 turned to connect the reservoir to vacuum. The mercury rises again in the reservoir bulb 13 until it comes back to a marked level when under atmospheric conditions. The valve 14 is now turned to an isolated position where it communicates with neither 15 or 16, and the air in the sample 8 is allowed to leak out into the chamber 6 and the tube 3. The valves 14 and 16 are then turned to atmosphere so that the mercury rushes back into the chamber 6 and submerges the sample again, driving the exuded air from the sample into tube 3. The chamber 6 is now moved vertically until the mercury levels are equal in both tubes and the pore volume or volume of the exuded air in tube 3 may be read. The porosity may now be simply calculated as a percentage of the original bulk volume of the sample corrected to allow for a volume of adsorbed air on the sample surface.

The wires can be applied by clipping tubes to projections at each end of a temporary former plate, round which the wire is wound in a flattened helix. After cementing in place the wires are cut suitably to leave wiring tags from one end of each bend 4: contact areas are then bared and plated. Two completed connectors may be fitted in a housing (Fig. 6) to connect to both sides of board 14. For fine pitched contacts the tubes may be deformed in shear along the gap before winding; so that after the adhesive has hardened, relaxation of shear flattens the coils. Expansion of the tape before winding can ensure that on relaxation the C-shaped turns are stuck to the tube over more than a semicircle, allowing diametrically opposed contact points.
