Patent EP-0042877-B1 (EP)
IPC: B01D59/30
Filed: 1980-12-25
Granted: 1984-12-19
Abstract: A process for separating carbon isotopes, which comprises contacting an aqueous solution containing acid dissociation type and non-dissociation type chemical species of carbon-containing acids with a solid phase anion exchange resin to thereby simultaneously conduct a carbon isotope exchange reaction between said acid dissociation type chemical species and non-dissociation type chemical species and adsorb said acid dissociation type chemical species on said anion exchange resin, thus C12 and C13 being separated into the solution phase and the solid phase, respectively, or vice versa, for the concentration of C13. This process is extremely effective and can be conducted inexpensively as compared with conventional separating processes by chemical exchange between gas and liquid phases, between gas and solution phases, or between solution and solution phases.

Granted: 1986-05-07
Abstract: An apparatus for electrically simulating a reciprocating gas pump or compressor includes unidirectional devices for simulating intake and discharge valves. The volume of the reciprocating cylinder is modeled by a fixed capacitor coupled in a feedback arrangement with a variable gain amplifier. The gain of the amplifier is preferably controlled by the contents of a digital memory device, which varies the gain to simulate the pumping action of a compressor. The device provides voltage outputs representing the pressure and volume readings obtained in the compressor being simulated.

Title: Deflection circuit
IPC: H04N3/18
Filed: 1982-02-15
Granted: 1986-12-17
Abstract: A deflection generator of a television receiver is coupled to a deflection winding for generating scanning current during a deflection cycle. The generator includes a retrace capacitor coupled to the deflection winding for forming a retrace resonant circuit therewith to produce a retrace pulse voltage during a retrace interval of the deflection cycle. An inductor and another capacitor form a second resonant circuit that is coupled to the retrace resonant circuit. A switching arrangement is coupled to a source of energy and the second resonant circuit in a push-pull configuration. The switching arrangement is responsive to a deflection rate switching signal to store during trace a controllable amount of energy from the source in the second resonant circuit. This stored energy is then transferred to the retrace resonant circuit during the retrace interval to replenish losses sustained during the deflection cycle.

Granted: 1985-09-04
Abstract: A method and device for packaging essentially conical objects, particularly ice-cream cones, in individual wrappings. The ice-cream cones (1) are advanced with the aid of holder members (7). A web (11) of shrinking foil is folded over the cones. The ice-cream cones are advanced up to two wheels (12, 13) formed with cogs (14). On the cogs of one of the wheels two jaws (15) and a heating wire (16) are provided. The opposite wheel (13) is formed on its cogs (14) with a back-up surface. When the ice-cream cones reach the wheels (12, 13) the foil is compressed between the cogs (14) and burnt off by the heating wire while at the same time vertical edges are formed in the foil and fused together in such a manner that individual wrappings are formed about each ice-cream cone (1). Hot air is finally blown against the part of the wrapping that is positioned below the cone edge so that this part of the wrapping is shrunk onto the ice-cream cone and the wrapping securely retained thereon.

IPC: F16F1/02
Filed: 1983-09-05
Granted: 1988-02-17
Abstract: Steel and process for its manufacture which is suitable for the production of springs, especially leafsprings for vehicles. The steel which is vacuum-treated is an ordinary low-carbon steel with 0.20 - 0.40 % C. Its composition is incidentally characterised in that the oxygen content does not exceed 0.040 % and in that boron is added to an amount of 0.002 - 0.004 % and titanium to an amount of 0.015 - 0.050 %. The addition of boron causes the hardenability to increase greatly, thus making it possible to keep the carbon content low and, in consequence, reducing the danger of destructive decarbonisation. A characteristic of the process of production consists in the fact that the steel is produced in an oxygen converter in such a manner that the nitrogen content in the ladle does not exceed 20 ppm, in that it is subsequently subjected to vacuum treatment and in that Al is added so that the amount of uncombined oxygen drops to max. 40 ppm, whereafter titanium and boron are added prior to continuous casting and rolling.

Abstract: The feed gas is partially burnt with oxygen-containing gas in a thermal Claus process plant, in which temperatures in the range of 850 DEG  to 1350 DEG  C. is maintained. Product gas which has been produced is passed through a catalytic Claus process plant (Claus catalysis plant), from which sulfur is withdrawn. The exhaust gas from the Claus catalysis plant is supplied to a desulfurizing plant. The sulfur compounds in the exhaust gas of the desulfurizing plant are converted to SO2 in a thermal aftertreating unit. When the rate of the H2S-containing feed gas is below a limit, which is between 20 to 35% of the total rate of feed gas permissible for the thermal Claus process plant, then recycled exhaust gas from the desulfurizing plant (recycle gas) is admixed to the feed gas at such a rate that the rate of the mixed feed and recycle gases exceeds that limit. The recycle gas is suitably heated to 200 DEG  to 400 DEG  C. before it is mixed with the feed gas.
