Abstract: A method and apparatus for continuous pressure comminution of brittle grinding stock such as cement clinker wherein simultaneous operations of unit grain comminution and product bed comminution are carried out in the roller gap of the same roller machine in such a manner that the grinding stock is first precomminuted by means of the unit grain comminution in a wider roller gap and immediately thereafter, the grinding stock fragments produced in the unit grain comminution are further comminuted by the technique of product bed comminution in the region of the narrowest roller gap. The continuous pressure comminution is characterized by a high pressure of more than 2 metric tons per centimeter of roller length, with a sifter being provided after the pressure roller.

Abstract: An optical waveguide filament is disclosed which comprises a cladding layer, a core and a barrier layer disposed between the core and cladding. The barrier layer comprises silica doped with B<sub>2</sub>O<sub>3</sub>, P<sub>2</sub>O<sub>5</sub> and GeO<sub>2</sub>. The core consists of an inner region and an outer region, the boundary between which is referred to as the core break-point. In the outer region of the core, the concentration of B<sub>2</sub>O<sub>3</sub> decreases linearly from its barrier layer level to zero at the core break-point, the P<sub>2</sub>O<sub>5</sub> increases at a rapid rate from the barrier layer level to a first concentration level at the core break-point and the GeO<sub>2</sub> remains at a constant value between zero and the barrier level. In the outer region of the core, the GeO<sub>2</sub> increases from some level up tothe barrier layer level to a greater value at the filament axis in a power law fashion. The P<sub>2</sub>O<sub>5</sub> also increases in a power law fashion from the value thereof at the core break-pointto a higher value at the filament axis, the increase in concentration of P<sub>2</sub>O<sub>5</sub> in the outer core region increasing at a rate greater than the concentration of P<sub>2</sub>O<sub>5</sub> would increase if the power law P<sub>2</sub>O<sub>5</sub> gradient extended into the outer core region. Also disclosed is a method of making a preform for such a filament.

Title: Improvements in or relating to the preparation of an aqueous dispersion of insecticide
IPC: A01N25/04
Filed: 1945-01-04
Abstract: An aqueous insecticidal dispersion is prepared by dissolving a a -bis (p-chlorophenyl)-b b b -trichlorethane (D.D.T.), in a very water-soluble organic solvent and then vigorously mixing the solution with a relatively large volume of water.  Suitable organic solvents are pyridine, a -picoline, acetone, and ethyl lactate.  If the water is hard, its enhanced surface tension should be reduced by the addition of a water softener.  The resulting suspensions may be mixed with other soluble insecticides or with fungicides such as sulphur, lime-sulphur, or Bordeaux mixture.  According to examples (1) a solution of D.D.T. in pyridine is dispensed in a large volume of water; (2) a solution containing D.D.T., sulphonated "Loral" T.A. (Registered Trade Mark), methylated spirit, and commercial pyridine, ethyl lactate or a-picoline is dispersed in water.  Specifications 547,871 and 573,832 are referred to.

Abstract: 553,010. Landing platforms for aircraft. FAIREY AVIATION CO., Ltd., and SMITH, C. H. C. Jan. 13, 1942, No. 502. [Class 4] A slipway for the return of aircraft to slips from which they have been launched is constituted by a number of cables extending aft from the vessel and supported at their after ends by floats and drogues or paravanes so adjusted that the drag imposed on the cables is sufficient to enable them to support an aircraft alighting thereon. As shown, the slipway comprises a series of cables a extending between fore and aft spreader beams b, e, the beam b being fitted with floats e<SP>1</SP> and drogues f. To enable the aircraft to be drawn forwards on to the vessel, the aircraft undercarriage is adapted to be engaged by a transverse cable h extending between blocks m slidable each on a cable a and connected to haulage cables k, the blocks being connected also by a beam g. The aircraft undercarriage n, Fig. 5, may be V-shaped and be provided with hooks o to prevent undue spreading of the cables a or when the aircraft is provided with retractable wheels, these may be replaced by an axle secured by quick-release fittings, to the stub-axles of the wheels, this axle being fitted with deck-hooks of known type which snap on to the cables and retard the forward movement of the aircraft while arrester gear on the tail thereof may grip the cable h and prevent overturning of the aircraft. Such deck-hooks may also be provided in association with the V-shaped undercarriage. The slipway may include telescopic guide channels extensible from alongside the hull of the vessel d and engaged by rollers on the beam e. With this arrangement the cables a may be arranged to be drawn over rollers at the stern of the vessel into a compartment below the deck.

Title: Improvements in or relating to electron discharge devices employing hollow resonators
IPC: H01J25/18
Filed: 1941-01-14
Abstract: 577,037. Electron discharge valves. BROADWAY, L. F. Jan. 14, 1941, No. 515. [Class 39 (i)] An electric circuit includes a velocity-modulation electron-discharge device in which a cathode surrounded by' or surrounding an annular resonator projects electrons in a number of radial directions through a gap in it, the gap being entirely open or having only a grid or grids joining its opposite edges and lying transversely of the path of the electrons, some or all of the electrons being returned through the gap by a reflecting electrode maintained at a suitable potential. An electron discharge device comprises a toroidal resonator surrounding or surrounded by a cathode which projects a stream of electrons in a number of radial directions through a gap in it, which gap is either entirely open or has only a grid or grids joining its opposite edges and lying transversely of the path of the electrons. As shown, an annular cathode 2 is mounted between disc form electrodes 3 which cause the electron beam to converge into a sheet which passes radially through a gap 5 in a toroidal resonator of dumb-bell section. The electrons are returned through the gap by a negatively-biassed pair of ring-shaped electrodes 7, which may be connected by a surrounding ring to form an electrode of U- shaped cross-section, or replaced by a ring- shaped electrode concave towards the gap 5. The portion of the resonator adjacent the electrode 7 may be substantially flat. Grids or conducting straps may join the upper and lower parts of the resonator, and the two parts may be coupled by a concentric line or other coupling when the electrostatic coupling between them is insufficient. Energy may be withdrawn by a concentric line coupling 8. A second resonator concentric with the first may be employed, and be coupled to it when the device is for use as an oscillation generator. For use as an oscillation mixer, the electrode 7 is maintained at such a potential that electrons exceeding a predetermined velocity are collected by it or by a further target electrode. The oscillations to be mixed may be applied to the same or to separate resonators. In another form a resonator of the transmission line type is used, comprising concentric cylinders extending through the glass envelope, the seal occurring at a voltage node as described in Specification 574,708. An axially-disposed cathode and focusing electrodes project radially-directed electrons through annular gaps in the two cylinders, the inner and outer peripheries of the gaps being bounded by grid-wires extending between the opposed edges of the cylinders. An annular reflecting electrode extends round the outside of the gap. A second resonator similar to the first may be arranged concentrically around it.
