Title: Electromagnetically Releasable Holding Magnet Arrangement.
Inventor: ALLETRU JEAN
IPC: H01H51/01
Filed: 1967-03-14
Abstract: 1,157,552. Electromagnetic switches. L'INDUSTRIE ELECTRIQUE DE LA SEINE. 14 March, 1967 [22 March, 1966], No. 11836/67. Heading H1N. A holding magnet for an electromagnetic tripping device has a branched magnetic circuit, one branch including a permanent magnet, a second branch in parallel with the permanent magnet and including a cylindrical surface on which an armature rocks and a third branch including an operating coil on a cone which has a pole end forming with the armature the operative air gap which is bounded by one flat and one part-spherical surface. As shown in Figs. 2 and 9, the three branches extend from a magnetic plate 11 and comprise, a permanent magnet 15, an extension 12 integral with the plate 11 and the cone 22 mounted within its coil 23. The armature 11 which co-operates with the part-spherical core end 25 rolls and slides on a magnetic shaft 17 secured to the extension 12. A member 40 attached to the armature 19 has arms 27, 28 and a slotted extension which extends on each side of the shaft 17 with a clearance J (Fig. 4). This ensures that in each direction of movement the initial armature motion is a friction free rolling motion on the shaft until the clearance J is taken up and then a sliding motion on the shaft (Figs. 5 to 8, not shown). The arrangement is bi-stable and the armature is held in the position shown in Fig. 2 by the permanent magnet until the coil 23 is energized to oppose the permanent magnet flux and allow a bias force F to move the armature. The bias may be applied by an adjustable spring 46. In an alternative arrangement (Fig. 12, not shown), the permanent magnet is on the opposite side of the shaft to the core and coil.

Title: Improvements in and relating to the destructive hydrogenation of solid carbonaceous material
IPC: C10G1/08
Filed: 1929-04-17
Abstract: 332,246. Harrison, C. F. R., Strong, H. W., and Imperial Chemical Industries, Ltd. April 17, 1929. Hydrogenation, destructive.-In the destructive hydrogenation at high pressures of coal or other solid carbonaceous material, an intimate mixture of a catalyst therewith is effected by treatment with an aqueous solution of the catalyst which is evenly distributed over the comminuted material, preferably by spraying, the material being agitated during the application. Solutions, preferably saturated, of nickel nitrate or ammonium molybdate are applied in this manner. After draining and it may be drying, the treated material is, if desired, mixed with oil and hydrogenated in the usual manner. Metals or oxides are converted to soluble salts and reduced during hydrogenation to the active condition. The amount of catalyst may vary between 0.01 and 5 per cent. of the weight of material treated. According to the Provisional Specification, only enough liquid is added to wet the particles without making the mass liquid or semi-liquid, and the strength of the solution depends on the amount of moisture initially present in the coal. In some cases hot solutions are employed. Where the soluble catalysts are absorbed by the coal, the excess liquor is removed by centrifuging, filtration, decantation &c.

Filed: 1936-05-02
Abstract: 471,991. Glass manufacture. PEARSON, T. F. May 2, 1936, No. 12474. [Class 56] Relates to a device for skimming the glass in a forehearth of the kind in which a submerged bridge 15, Fig. 2, extending across the forehearth at a distance from the front wall 10, defines a body of glass from which charges are gathered by suction. According to the invention, a skimmer 20 dips into the glass near one side of the forehearth at position A, Fig. 4, then moves across the gathering area to position B when it commences to swing about one end, through positions C, D, and E, until it pushes the skimmings over the bridge and allows fresh glass to rise into the gathering- area through the channel below the bridge 15. At the end of its stroke, the skimmer is raised out of the glass and is moved in its own plane to position F while the chilled glass drains away from it. Finally, it swings backwards through positions' G, H to its initial position, and the operation is repeated. The skimmer is carried by an arm 22 pivoted to a carriage which is reciprocated along a transverse guide 30 by means of a driving-rod 37, the guide also being reciprocated vertically by means of lifting-rods 33 operated by any suitable means. Cams 34, 34a secured to the framework of the guide 30 impart the required swinging movements to the arm 22 that supports the skimmer.
