Title: Improved method of lining metal pipes
IPC: B29C63/26
Filed: 1933-05-19
Abstract: Metal pipes are lined with bitumen by mounting them on a horizontal axis, preheating them, preferably electrically, inserting bitumen loaded with diatomaceous earth or powdered asbestos into the interior in stick form, and rotating the pipe as the bitumen melts to distribute the lining evenly.  The rate of rotation may be increased, subsequently, to consolidate the lining centrifugally.  Cooling by air or water spray on the exterior may be used to expedite setting during the faster rotation.  Ring dams may be inserted in the pipe ends to retain the material in the case of thick linings, and caps may be spaced from the ends of the pipe to allow the spigot end to be covered, and a ring of bitumen to be formed at the bottom of the socket.

Title: Improvements in or relating to short wave oscillators and apparatus for use in association therewith
IPC: H01J25/72
Filed: 1932-05-23
Abstract: 400,319. Thermionic valves. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.- (Assignees of Hansell, C. W.; Port Jefferson, Long Island, New York, U.S.A.) May 23,1932, No. 14595. Convention date, June 24, 1931. [Classes 39 (i) and 40 (v).] An ultra-short wave oscillator comprises a discharge device having an anode and cathode the electrodes being so arranged and dimensioned that the time of flight of an electron to the anode is substantially one-half (or an odd multiple thereof) of the period of oscillation of the anode and any extension of it, considered as an electrically oscillating body. In one construction, an anode 4, Fig. 1, shaped as a hollow water-cooled tube, as shown in Fig. 1a, surrounds a cathode 2 and grid 16. The anode extends outside the bulb and the distance to a plate 90 is made an odd number of quarter wave-lengths of the oscillations desired. A source 80 keeps the grid-anode potential difference constant, and the cathode is connected to earth through a resistance 60 and capacity 70, thus varying the effective gridbias. In another construction, Fig. 2, the indirectly-heated cathode 2 and the grid 16 are supported from a pinch 10. The anode 4 surrounds them and is supported from a pinch 12. The anode 4 is made one half-wave length long, and a potential is applied to it at its mid-point. The anode may extend outside the bulb. The grid-bias may be made more negative after oscillations have commenced by coupling a rectifier capacitatively to the anode and applying the rectified output to the grid or by connecting the grid to the cathode through a resistance through which the anodecathode current flows. The oscillations may be modulated (1) by means of a key in the anode lead, (2) in telephony by the Heising system in the lead connecting the source of plate potential through a choke to the plate, (3) by connecting the source of plate potential to the plate through the secondary of a transformer the primary of which is modulated, (4) by applying high or low negative potentials to the grid by means of a key and so preventing and permitting oscillation, (5) by modulating the potential difference between grid and cathode, (6) by applying modulation input to the grid of a valve whose plate is connected to the cathode of the oscillator and earthing the grid of the latter. Dimensions of an oscillator constructed in accordance with the invention and as shown in Fig. 2 are given. Specification 379,395 is referred to. The Specification as open to inspection under Sect. 91 also comprises.a receiving arrangement for ultra-short wave oscillations consisting of a thermionic valve having a negatively biased plate, the plate lead coupled inductively to the aerial and earthed through condensers at two different points, and a positively biased grid, the grid lead being in series with the telephones and connected to earth through condensers at two different points. This subject-matter does not appear in the Specification as accepted.

Abstract: 496,235. Floors. DOUGLAS, A. H., LEFEBURE, V., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. May 27, 1937, No. 14763. [Class 20 (iv)] A reinforced-concrete floor comprises rectangular porous mineral blocks 2 suspended between steel joists 1 by means of metal crosspieces 4, the ends of which are notched to engage with the bottom flanges 6 of the joists, the blocks being placed side by side with a cross-piece between each pair, and the arrangement being such that the lower surfaces of the blocks are brought below the level of the bottoms of the joists. The cross-pieces 4 may be of channel, I, L, inverted T-section, or may consist of vertical strips having a number of lateral projections, or horizontal strips, the ends of which are twisted through 90‹ and notched to engage with the joist flanges. If necessary, the ends of the cross-pieces may be turned upwardly to bring their lower surfaces below the level of the joists. The long narrow sides of the blocks 2 are recessed or grooved to engage with the cross-pieces 4. To ensure that the blocks fit tightly against one another, metal ribbon may be passed around neighbouring or alternate cross-pieces and drawn tight. When the blocks have been positioned, planks 8 are nailed to adjacent blocks below the joists 1 as shown, and concrete poured into the mould thus formed. If desired, metal reinforcing bars may be positioned in the spaces 9 below the joists, prior to the pouring of the concrete. The blocks 2 are made of such material and thickness that they will receive nails without spalling. Suitable blocks are cellular plaster of Paris or anhydrite plaster blocks, such as are described in Specification 381,155, Portland cement-coke breeze blocks, aerated Portland cement blocks, or agglomerated pumice blocks, which may be reinforced, if desired, by paper, pulp board, canvas, or wire gauze.

The process of preparing a stable dispersion of a basic, magnesium-containing, inorganic compound in a non-volatile carrier, said inorganic compound being present in the form of particles having a diameter not exceeding about 0,25 micron comprises admixing a glycol ether solution of an oilsoluble magnesium alkoxide-carbonate complex, an oil-soluble dispersing agent, a nonvolatile carrier, and water in an amount which is a stoichiometric excess of that required to react with the magnesium alkoxide-carbonate complex, hydrolysing the magnesium alkoxidecarbonate complex to an oil-insoluble magnesium-containing inorganic compound, and then removing the volatile material.  The non-volatile carrier is usually a mineral or synthetic lubricating oil, but corn, cottonseed, castor, lard, and sperm oils polyproprylene, polyoxypropylene, esters of adipic and azelaic acids with butyl, 2-ethylhexyl and dodecyl alcohols, diethyl decanephosphonic acid ester or tricresyl phosphate may be used diluted, if desired to reduce viscosity, with petroleum naphtha, hexane, heptane, octane, benzene, toluene or xylene.

Title: Coating compositions
Inventor: JACOB BASIL
IPC: H01B3/30
Filed: 1953-06-01
Abstract: A composition suitable for use in electrical insulation comprises a mixture of a polyvinyl acetal resin, preferably polyvinyl formal, with an organic polyisocyanate in the form of an adduct with an organic compound having an active hydrogen atom, the adduct containing no active isocyanate groups but being capable of acting as an isocyanate at elevated temperatures. Suitable polyisocyanates are ethylene, polymethylene, cyclohexanediol, p-phenylene, m-phenylene, p,p1-diphenyl and naphthalene diisocyanates and partial condensation products of diisocyanates with aliphatic polyhydric alcohols containing two or more isocyanate groups; the corresponding polyisothiocyanates may be used.  Suitable adduct-forming compounds are ethyl acetoacetate, phenol and polyhydric phenols such as diphenylol propane.  In an example, there is used an adduct obtained from m-toluylene diisocyanate, trimethylol propane and 1:4-butanediol. If desired the compositions may be modified by the addition of phenol-aldehyde resins, for example the polyisocyanate adducts may be admixed with the polyvinyl acetal resin/phenolaldehyde resin compositions of Specification 669,127.  The compositions may be dissolved in a solvent, such as a mixture of cresol and xylol, the resulting enamel applied to a wire and heated to cause reaction between the polyisocyanate adduct and the polyvinyl acetal resin whereby the thermoplasticity of the latter is reduced. Specification 552,444 is also referred to.
