Title: Apparatus for the instantaneous reproduction of handwriting or drawings by wired or electromagnetic coupling of a local pen and accessories to a remote pen or cathode ray or the like and associated equipment
IPC: G08C21/00
Filed: 1945-06-27
Abstract: 605,719. Writing telegraphs. TELCS, M. L. June 27, 1945, No. 16413. [Class 40 (i)] In a writing telegraph, the stylus itself modulates two carrier waves in accordance with the co-ordinate components of its movement. Two carrier frequencies developed in VOH, VOV, Fig. 2, are applied over circuits LH, LV to the pen P which forms one element of a condenser; the pen moves on a dielectric surface A, which is inclined in one direction to condenser plate B and inclined in a direction at right angles to condenser plate C, so that oscillations from VOH, VOV are transferred to amplifiers VAH, VAV over condensers whose value is dependent upon the position of the pen, thus producing amplitude modulation of the carrier waves. At the receiver, the two carriers are rectified and applied to a cathoderay tube with a screen having a long after-glow, Fig. 3 (not shown). The carriers may be frequency modulated, Fig. 1 (not shown).

Title: Improvements in or relating to the moulding of rubber articles by dipping or like processes
IPC: B29D99/00
Filed: 1933-06-10
Abstract: The surface of moulded rubber sheets or articles is roughened by sprinkling it while in the unhardened state with particles of pulverulent, granular or like material which are chemically inert with respect to the rubber and are removed from the finished product to leave a roughened or pitted surface due to the mechanical indenting effect of the particles.  The invention is applicable specially to the manufacture of rubber gloves and like articles where a good gripping surface is desirable.  In one method of making gloves, a former is dipped into rubber solution and the deposit is sprinkled with crystals of magnesium sulphate which become partly embedded in the film and are subsequently washed off the dried film. Alternatively, a material such as sand may be used, which can be removed from the dried film by washing, rubbing or brushing.  Sheets or articles produced by dropping, spreading, or spraying latex or other rubber-like raw material may be similarly treated.

Title: Polymerization of ethylene oxide in organic diluents
IPC: C08G65/26
Filed: 1957-05-28
Abstract: Solid water-soluble polyethylene oxide with a reduced viscosity greater than 1 is prepared by polymerizing ethylene oxide, either in an organic diluent in which the monomer is soluble and the polymer insoluble or in a medium in which both monomer and polymer are soluble, using as catalyst a carbonate of a metal of atomic number between 11 and 57 and appearing between potassium and tin in the electromotive series (examples are Mg, Ca, Sr, Ba, Zn, Cd, Fe, Co, Ni, Cr, and Mn), or an alkaline earth metal derivative of an organic hydroxy compound which has been treated with carbon dioxide and water to increase its weight by up to 70%, or, when using a solvent for both monomer and polymer, either an amide of a Group II metal with atomic number between 19 and 57 or a hexammoniate of Ca, Sr or Ba. If desired hydrocarbon gas, e.g. butane may be added to the reaction mixture as a stabilizer. Diluents in which the polymer is insoluble may be saturated hydrocarbons, e.g. pentane, hexane, heptane, ethyl-pentane, octane, decane, alkyl cyclohexane, or decahydronaphthalene; or dialkyl ethers or their alkyl substituents, the alkyl groups having 2-6 carbon atoms, e.g. diethyl ether, dibutyl ether. Suitable solvents for both monomer and polymer are benzene, toluene, xylene, ethylbenzene, chlorbenzene, anisol, phenyl ethyl ether, diphenyl ether, the dimethyl or diethyl ethers of ethylene, propylene or diethylene glycol, dioxane, dimethyl dioxane, tetrahydrofuran or tetrahydropyran.  The carbonate catalysts should contain at least ,01% of sorbed water.  If desired the ethylene oxide may be distilled through a drying agent to remove water and through a product to remove carbon dioxide before being polymerized.  In examples ethylene oxide is polymerized in presence of (1) pentane and strontium carbonate; (2) isopentane and strontium; (3) n-heptane and barium methylate which had been exposed to an atmosphere of CO2 and water until its weight had increased 60%; (4) cyclohexane and strontium carbonate; (5) diethyl ether and strontium carbonate; (6) and (8) benzene, strontium carbonate and butane; (7) toluene and strontium carbonate; (9) benzene, strontium methylate treated with CO2 and water until its weight increased by 60% and butane; (10) toluene and calcium amide; (11) toluene and calcium glycoxide treated with CO2 and water; (12) toluene and manganous carbonate; (13) anisole and strontium carbonate; (14) dioxane and strontium carbonate; (15) ethylene glycol dimethyl ether and strontium carbonate.

Abstract: 1,173,982. Imino and amino compounds. MONSANTO CO. 13 April, 1967 [13 April, 1966], No. 17112/67. Addition to 1,107,336. Heading C2C. According to the parent Specification Schiff's bases are made by heating primary amines with aldehydes or ketones in the presence of a catalyst consisting essentially of elementary carbon. This process is now modified in that elementary carbons are used having a bound acidity (determined as described in the parent Specification) of at least 0À3 milliequivalents per gram. As in the parent Specification, the process may be combined with the simultaneous or subsequent reduction of the Schiff's base with hydrogen in the conjoint presence of elementary carbon and a hydrogenation catalyst, and the process may be further modified by using as a starting material the nitro compound corresponding to the desired primary amine, the catalytic reduction of the nitro compound, the formation of the Schiff's base and its reduction being effected as a continuous operation. Thus, in Example 1, N-isopropylaniline is produced from nitrobenzene and acetone.
