Title: Improvements in or relating to scales and instruments embodying the same
IPC: G04B47/06
Filed: 1943-09-07
Abstract: 579,985. Watches. NEWTON, E. P. (Reece, F. A.). Sept. 7, 1943, No. 14671. [Class 139] [Also in Group XIX] An instrument, by which a pilot can calculate ground speed or distance travelled, has a scale the spacing of whose graduations is infinitely and uniformly variable throughout its length. As shown in Figs. 1, 3, a wrist watch has a post 19 carrying a dial 20 graduated in hours. An elongated minute hand 23 traverses a scale 24 in two hours, the scale 24 being a ring held within the outer edge of the case 15 by a bezel 17. A dial 25 rotatable by knob 29 is mounted on the post 19 and bears a spiral slot 41. A number of spirals identical with the slot 41 are inscribed on a disc 27, mounted on post 19 under dial 25, to represent various speeds. The'points on these spirals equivalent to equal distances are connected as shown at S and Q, Fig. 8, by differently coloured lines 43 and the portions of these lines intersecting and visible through the slot 41 which constitutes a curved scale are the graduations of said scale. The spacing of said graduations can be varied by turning disc 27. In use, the pilot, on starting, sets the zero of dial 25 to coincide with the minute hand 23. When he passes over a landmark he rotates dial 27 by knob 50 until the number of coloured lines 43, between the zero and the minute hand 23, visible through the spiral slot 41 corresponds to the known distance of this landmark from his starting point. The graduation opposite index 42 represents the speed of the aircraft. Conversely the device can be used to calculate distances when the speed is known. Specification 555,155 is referred to.

Abstract: 311,945. Gratze, E. V. Hayes-, (Leyst, C.). May 21, 1928. Pulp, preparation of.-Paper pulp is produced from straw, esparto grass or the like by decomposing the material by cooking in lime and water to free the cellulose and then milling or grinding to a flour-like consistency, or alternatively milling or grinding the material to a flour-like consistency and then freeing the product from glutinous, resinous, silicious, pectinous and other impurities by cooking in lime and water. The decomposition is carried out by cooking in an open boiler with excess of water and about 30 per cent of lime for about six or eight hours. The material is then washed and ground either before or after drying. In the alternative process the grinding precedes the cooking. As a preliminary the raw material may be exposed in a moist or wet condition to a temperature of 30‹ C. for from three to six days, with or without a small proportion of alkali, to assist the development of the bacillus butyricus and the elimination of the pectin impurities.

Title: Improvements in method of forming boron nitride sheets
IPC: C01B21/064
Filed: 1965-04-13
Abstract: A body comprising a plurality of parallel pyrolytic boron nitride layers with alternate layers of a different pyrolytically deposited material is contacted with an intercalation material in fluid form, whereby the intercalation material enters the alternate layers decreasing the strength between them so that the boron nitride layers may be readily separated as sheets.  The alternate layers may be pyrolytic carbonaceous material, e.g. graphite, or molybdenum, tantalum or aluminium nitride. The intercalation material is an electron acceptor material with a high electron affinity or an electron donor material with a low ionization potential, e.g. H2SO4 with a small amount of HNO3 or KClO4; AlCl3, BCl3, K, Co, ICl, Br2, AlCl, FeCl3, NaOH or KOH.  The composite body comprising the boron nitride and alternate layers is built up by first depositing a layer of pyrolytic boron nitride from a vapour of b -trichloroborazole; or from BCl3 or B2H6 together with NH3, on to a plate of graphite and then depositing a layer of pyrolytic carbon, from methane gas, on to the boron nitride layer.  Subsequent layers are built up by repeating the operation.
