Abstract: 1362268 Aromatic polymers and hardened foams thereof ALBRIGHT & WILSON Ltd 23 March 1972 [26 March 1971] 7891/71 Headings C3R and C3C [Also in Division B5] Polymers are prepared by reacting (1) an aralkyl ether of formula R<SP>1</SP>-(CH 2 OR) a  and/or an aralkyl halide of formula R<SP>11</SP>-(CH 2 X) a  where R<SP>1</SP> and R<SP>11</SP> are divalent or trivalent aromatic hydrocarbon or hydrocarbon ether radicals and optionally contain inert substituents in the aromatic nucleus, R is a C 1-6  alkyl radical, X is Cl, Br or I, and a is 2 or 3 with (2) a molar excess of a phenolic reactant mixture which comprises both phenol and beta-naphthol. The reaction may be carried out by heating the reactants at 130-200‹ C. preferably in the presence of a catalyst, e.g. cupric sulphate or diethyl sulphate. Examples of reactant (1) include 2,3,5,6 - tetrachloro - 1,4 - di(methoxymethyl) - benzene and 2,3,5,6 - tetrachloro- 1,4 - di - (chloromethyl)benzene and paraxylyene glycol dimethyl ether. The products obtained by the above reaction may be converted to higher molecular weight cellular resins by heating, normally at 100-200‹ C., with a novolac hardening agent, e.g. hexamethylene tetramine, quinone, chloranil, anhydroformaldehyde aniline and ethylene diamine formaldehyde. In the example phenol, betanaphthol and 1,4-di(methoxymethyl) benzene are condensed in the presence of cupric sulphate. The product is ground to a fine powder and mixed with hexamine. On heating a foamed resin is formed. Uses.-The foamed resins can be used for high strength lightweight, load-bearing structure and for heat and electrical insulation.

Title: Improved device for producing an electric reference magnitude
IPC: G05B1/02
Filed: 1950-03-30
Abstract: 681,213. Automatic regulation. WILLHEIM, R. March 30, 1951 [March 30, 1950], No. 7987/50. Class 38 (iv). In Fig. 4 a centre-tapped coil N is supplied from A.C. source E. Connected across one half of coil N is a linear inductance L alone, while across the other half is an equal linear inductance L in series with a saturable inductance S. The zero-current inductance of saturable inductance S is much greater than inductance L and the arrangement results in a current in common path R which is substantially independent of variations of voltage and frequency of source E or of variations in the load supplied through a bridge rectifier H. The rectified current flows through a rheostat W, the resistance of which is low compared with the impedance of linear inductance L, to produce a constant voltage. Rheostat W serves to adjust the voltage to be maintained. Slight variations due to incomplete saturation may be compensated by making the linear inductance L which is alone, slightly larger than the other linear inductance by adjustment of its tap, movement of its core or the addition of series air-cored coils. To compensate for temperature variation a resistance with a positive temperature coefficient, responsive to the temperature of the saturable reactor core, may be connected in parallel with rheostat W. Screening of the linear inductances is referred to. Rheostat W may be replaced by a coil producing constant excitation for a constant current supply arrangement involving a transductor.

Title: Process for the manufacture of active absorbing carbon and phosphoric acid and its compounds
IPC: C13B20/12
Filed: 1924-03-29
Abstract: Bone char or bone char dust is leached with a dilute solution of phosphoric acid in order to obtain activated carbon and phosphoric acid.  The bone char, which may receive a preliminary re-calcination, is washed with water after leaching and dried and the combined washing water and leaching liquor is treated with sulphuric acid in amount considerably less than the equivalent of the calcium and magnesium present in solution.  On evaporation, di-calcium-hydrogen phosphate is precipitated which may be removed and regarded as the finished product or may be decomposed with sulphuric acid to give calcium sulphate and phosphoric acid for re-use.  The filtrate from the di-calcium hydrogen phosphate is treated with sulphuric acid in quantity sufficient to precipitate most of the calcium and magnesium as sulphates.  The latter are separated and the mother-liquor containing phosphoric acid is treated for the removal of the salts of magnesium and the alkalies which are present.  Waste liquors which are too dilute to warrant evaporation may be treated with lime to recover their content of phosphate.ALSO:Bone char or bone char dust is leached with a dilute solution of phosphoric acid in order to obtain activated carbon and phosphoric acid.

Title: Cathode ray tube systems
IPC: H04N9/24
Filed: 1952-03-31
Abstract: 753,448. Automatic control systems for cathode-ray tubes. PHILCO CORPORATION. March 31, 1952 [April 3, 1951], No. 8143/52. Class 38 (4). In a dot-sequential threecolour type television receiver, Fig. 3, line synchronizing pulses are separated at 15 to control a line oscillator 17 the output of which is amplified by a valve 19 to supply line coils 21 of cathoderay tube 13 through an autotransformer 42 associated with a damping diode 43 which conducts during the whole of the scan. The screen of the cathoderay tube comprises vertical stripes 29, 30, 31, Fig. 2, emissive of red, green, and blue light respectively covered by an aluminium backing 33, and vertical gold stripes 34, having secondary emission characteristics different from those of the backing placed over every third colour stripe. Scanning of stripes 34 by the cathoderay beam produces across a resistor 36 connected between the screen and second anode 35, voltage pulses which synchronize an oscillator 39. Means may be included to remove other signals present in the voltage developed across resistor 36. Colour synchronizing signals are transmitted at the end of each line and are separated at 16 to synchronize an oscillator 25. The D.C. signal output of a comparator 40 representative of the difference in phase of the outputs of the two oscillators 25 and 39 controls a triode valve 45 so connected across a voltage booster capacitor 44 that it controls the current through damping diode 43 and hence the rate of scan so that the beam is always on a stripe of the colour appropriate to the signal being received regardless of non-linearities of response, non- uniformity of stripes or transmission path changes. In a modification, Fig. 1 (not shown), the line transformer is double-wound and the comparator output directly controls the damping valve which is a triode. Specifications 753,441, 753,442, [Group XL (b)], and 753,444 are referred to.
