Title: Transmission system
IPC: G01S13/32
Filed: 1970-06-18
Abstract: 1320349 Radar PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 18 June 1970 [21 June 1969] 29617/70 Heading H4D In a radio system a modulating signal comprises a first train of binary pulses in irregular succession combined subtractively with a similar train shifted back from the former by one or two clock pulse periods from which clock pulses the binary trains are derived. In a radar embodiment, a first train Fig. 2a is produced at stage 13 of a feedback shift register 8; a second train, Fig. 2c which is advanced in time by two periods D relative to the first train, is produced by an adder 14. The difference between the two trains, i.e. a ternary pattern Fig. 2e, amplitude or frequency modulates a carrier from an oscillator 4. At the receiver, the output from a similar shift register 8<SP>1</SP>, according to the Fig. 2a pattern, is applied to a product modulator 22, together with the output of a demodulator 20 (which will be a time-delayed waveform corresponding to Fig. 2e) and the output of modulator 22, after smoothing by an integrator 33, corrects (by means of a variable reactance 24) the phase of local clock pulses supplied by a generator 15<SP>1</SP>. To measure range the outputs of AND gates 26, 27 are applied to a time measurer 25. Singleside-band transmission and reception may be utilized, Fig. 3 (not shown). In another embodiment, suited to integrated circuit construction, a digital differencing circuit comprises inverters and AND gates, Fig. 5 (not shown). The invention affords satisfactory operation in high noise levels e.g. noise 25 dB above the signal.

Title: Improvements in or relating to the manufacture of piezo-electric resonators
IPC: H03H3/04
Filed: 1962-08-03
Abstract: 971,571. Piezo-electric resonators. TELEFUNKEN PATENT-VERWERTUNGSG.m.b.H. Aug. 3, 1962 [Aug. 10, 1961], No. 29850/62. Heading H1E. The resonant frequency of a piezoelectric e.g. quartz, resonator is adjusted by evaporating metal from or on to an electrode, the evaporation being effected by means of radiant energy. The method is applied to an electroded resonator 3 already mounted within an hermetically sealed enclosure 6. Heat is applied either to an electrode or to a piece of foil 5 made of the same metal, e.g. silver, platinum, as the electrode. Energy from an external source, e.g. a glow discharge lamp 7, is concentrated on to the required spot by e.g. an optical system 8, 9. The lamp may be pulsed to give an output of 60-100 watt-secs. per flash. A circuit for automatically performing the adjustment comprises an oscillator 11 controlled by the resonator 3 and a standard-frequency oscillator 12. The outputs of the oscillators are compared by a device 13 which switches off the pulse generator 10 when the frequency difference reaches zero or some other fixed value. An electron beam may be used instead of visible radiation.

Title: Steam generation and compositions for inhibiting foaming
IPC: B01D19/04
Filed: 1948-11-22
Abstract: Monoethers of polyoxyalkylene glycols having a molecular weight of at least 500 and in which the hydroxy and ether groups are attached to different terminal carbon atoms are prepared by (1) reacting the appropriate alkylene oxide or mixture of alkylene oxides with a monohydric alcohol, or (2) reacting alkyl or aryl halides with the appropriate alkali metal alcoholate.  The alkylene radical is preferably ethylene or propylene but polyalkylene chains containing both ethylene and propylene groups may be produced.  The ether groups may be derived from monohydric alcohols or monobasic phenols, e.g. methanol, ethanol, propanol, isopropanol, butanols, cetyl alcohols, octadecanol, cyclohexanols, phenols, cresol, benzyl alcohol, or from monohydric alcohols or phenols having substituent groups, e.g. halogeno, nitro, cyano, alkyl and alkoxy groups, in the hydrocarbon chain or aromatic ring.  Examples are given of the preparation of the monobutyl, monolauryl and monocetyl ethers of polyoxyethylene glycol, the monocetyl, monophenyl, monocyclohexyl and monobenzyl ethers of polyoxypropylene glycol and the monobutyl ether of polyoxyethylene-oxypropylene glycol.  The compounds are employed as foam-inhibiting agents.ALSO:The formation of foam in steam generators is minimized by the addition to the boiler water of a monoether of a polyoxyalkylene glycol having a molecular weight of at least 500, and in which the hydroxy and ether groups are attached to different terminal carbon atoms.  The alkylene radical is preferably ethylene or propylene, but polyalkylene chains containing both ethylene and propylene radicals may be employed.  The ether groups may be derived from monohydroxy alcohols or monobasic phenols, e.g. methanol, ethanol, propanol, isopropanol, the butanols, cetyl alcohol, octadecanol, cyclohexanols, phenol, cresol, benzyl alcohols, or from monohydric alcohols or phenols having substituent groups, e.g., halogeno, nitro, cyano, alkyl and alkoxy groups, in the hydrocarbon chain or aromatic ring.  The foam-inhibiting agents, of which numerous examples are given, may be employed in admixture with dispersants, e.g. tannin, sodium lignin sulphonate, desulphonated lignin, sulphated oils, soaps of oleic acid or tall oil, soda ash, orthophosphates and polyphosphates in the form of powdered or briquetted compositions.  To nullify the effects of magnesium salts in the water, hydroxylated organic materials such as tannic acid, gallic acid, pyrogallol, catechol and phloroglucinol may be incorporated in the compositions.

Title: Improvements in and relating to the decomposition of titanium salt solutions by hydrolytic precipitation
IPC: C01G23/053
Filed: 1937-11-05
Abstract: In a process for the production of titanium dioxide having the rutile crystalline structure wherein an aqueous solution of titanium tetrachloride, titanium fluoride, or a complex titanium fluoride compound is hydrolytically precipitated and the precipitate is calcined, hydrolysis is effected in the presence of a small amount of a negative polyvalent ion, which, with a titanium fluoride or complex fluoride solution, has a valency of two or more, and with a titanium tetra-chloride solution, has a valency of three or more, the substance from which the negative polyvalent ion is derived being present in an amount not greater than 0,01 mol of the substance to each mol of titanium reckoned as TiO2.  The polyvalent ion may be obtained by adding oxalic, tartaric, sulphuric, arsenic, carbonic, phosphoric, or citric acid or an alkali metal salt of one of these acids to the solution.  Hydrolysis may be effected by simple boiling, by addition of a solution containing the ion to the salt solution, or by adding the salt solution to the solution containing the ion. Preferably the acid or salt is dissolved in a large volume of water, the temperature raised, and the titanium salt solution then added. Examples are given of the hydrolysis of a tetrachloride solution and a solution of the compound TiF4.2NH3 in the presence respectively of citric acid and sodium sulphate. Specifications 308,725, [Class 1 (iii)], 433,960, and 481,892 are referred to.  The Specification as open to inspection under Sect. 91, comprises also precipitation of the titanium dioxide by an alkaline hydroxide or ammonium carbonate in the presence of the polyvalent ion.  This subject-matter does not appear in the Specification as accepted.
