Title: Improvements in methods of and apparatus for the electrolytic manufacture of metallic magnesium
IPC: C25C3/04
Filed: 1935-01-11
Abstract: 447,083. Electrolytic production of magnesium. KATO, Y., 1220, Togoshimachi, Ebara-ku, Tokyo. Jan. 11, 1935, No. 1077. Convention date, March 30, 1934. Drawings to Specification. [Class 41] Magnesium is produced by electrolysis of a molten bath comprising chlorides of magnesium and alkali metals, magnesium oxide and/or carbonate and a reducing agent such as carbon or carbonaceous material in a cell in which the active area of the anode is more than twice that of the cathode ; liberation of chlorine is reduced by these measures. The magnesium oxide may be supplied in the form of basic chloride. Chlorides of alkaline earth metals other than magnesium may be added to the bath. Calcium fluoride may also be added to promote collection of the magnesium as globules. The process may be carried out in a cell comprising a central cathode surrounded by a number of segmental anodes secured together by an insulating head plate and connected by a conducting ring, the electrodes being separated by a diaphragm of earthenware or asbestos. In an example the initial electrolyte contains 1 mol. of magnesium chloride, 1 mol. of potassium chloride, and 1 mol. of sodium chloride. To this a mixture of 80 gms. of magnesium and 12 gms. of carbon is supplied from time to time to the anode compartment ; this is in part dispersed through the electrolyte, part however remaining floating. Magnesium is collected at the surface of the electrolyte. According to the Specification as open to inspection under Sect. 91 the magnesium oxide or carbonate may be substituted by hydrated magnesium chloride. This subjectmatter does not appear in the Specification as accepted.

Title: Feeding mechanism for sewing machines
IPC: D05B27/22
Filed: 1941-01-29
Abstract: 544,091. Sewing-machines. FAIRWEATHER, W. C. (Singer Manufacturing Co.). Jan. 29, 1941, No. 1165. [Class 112] Feed by dogs. The feed shaft 65. Fig. 2, is actuated through a feed-reversing mechanism which includes a rocker 74, pivoted at 75 and oscillated from a top shaft 16 by a link 79, and a slide 71, mounted on a bar 72 on the rocker and pivotally connected to a pitman 70. In order to move the slide 71 from one end to the other of the bar 72, a hand-operated shaft 88 carries a lever-arm 92 upon which are pivoted two similar links 96, 102 having lost-motion pin- and-slot connections 98 with the pitman 70. The arm 92 is urged to one or other of its extreme positions by means of a spring 106 and a link 104, the line of action of which crosses the centre of the shaft 88 when the slide 71 is moved along the bar 72. This causes the spring 106 to press the effective link 96 or 102 against the pin 98 whilst the other link rides idlv upon it. The links 96, 102 have a length equal to the distance of the slide 71 from the shaft 75 and the parallel motion which is thus provided reduces the vibration which is transmitted back to the handoperated shaft 88. The feed-regulation is effected by a variable throw eccentric 80. The feed motion is transmitted to a feed slide 62. Fig. 4, by an arm 64 on the shaft 65 and the slide has a U-shaped part, similar to the part 44, which embraces a concentric part of the shaft and provides a forward guide for the feed slide. The feed dog 37 is secured by a screw 43 upon a feed plate 41, which is slidingly mounted in the feed slide 62 and carries a U-shaped part 44 embracing a feed-lift eccentric on the shuttledriving shaft 32.

Title: Radiation detector
Inventor: MUNDAY CHARLES WALTER
IPC: G01N21/35
Filed: 1953-01-16
Abstract: 740,374. Electric measuring instruments; thermocouples. DISTILLERS CO., Ltd. Jan. 1, 1954 [Jan. 16, 1953], No. 1296/53. Classes 37 and 53. [Also in Group XL (b)] A radiation detector is made in the form of a moving-coil instrument, and comprises a frame of slightly diamagnetic material supporting a loop consisting of two wires joined at opposite ends to form two thermocouples each thermally connected to a lamina of radiation-absorbing material the frame being mounted between the poles of a magnet so as to permit axial rotation. As shown, Fig. 1, a rigid brass structure positioned between the poles 2, 3 of a magnet carries a quartz frame 4 by means of suspension fibres 6, 7 which may be of gold strip or quartz fibre. The frame should be of a diamagnetic material which, with a para-magnetic loop, forms an arrangement of zero susceptibility. The quartz frame supports a loop of wire by means of rigid quartz fibres 11, attached to opposite sides of the frame. The loop is formed of two wires 12, 13, one of a palladium/gold and the other a platinum/iridium alloy. At the junctions of the wires are discs 17 of radiation-absorbing material such as gold foil covered with gold black. The main frame 1 is provided with a torsion head 9. Inequality of temperature of the two junctions produces a current in the loop, which with its quartz frame is then deflected in the magnetic field. In the arrangement of Fig. 5 (not shown) the quartz frame carries an additional coil of wire which is fed with the amplified output of a photo-electric cell receiving light reflected by a mirror also mounted on the quartz frame. The current in this coil restores the quartz frame to its zero position and the photo-cell output is measured or recorded. The application of the invention to radiation gas analysers of known type is described. In the arrangement of Fig. 2 (not shown) in which a pair of beams, one having moved through a test cell and the other a comparison cell are compared each beam is direoted to one of the junctions. The beams are concentrated on to the junction by funnels, the interiors of which are coated with a reflecting film. In a modification (Fig. 3, not shown) two of the cells containing gas are shaped as funnels. In the arrangement of Fig. 3 (not shown) wherein two beams are " chopped " alternately, the beams are divided sequentially on to a single junction, the other junction being used for comparison purposes only. Alternatively a part of the radiation from the source may be directed on to it to eliminate errors due to changes in source intensity. Specifications 683,952 and 703,241, [both in Group XL (b)], are referred to.
