Title: The removal of no from industrial gas mixtures
IPC: C10K1/18
Filed: 1961-08-24
Abstract: 917,023. Purifying gas mixtures. STAMICARBON N.V. Aug. 24, 1961 [Aug. 27, 1960], No. 30609/61. Class 55 (2). Nitric oxide is removed from gas mixtures such as coke oven gas, cracking gas or producer gas, by adding to the gas an unsaturated hydrocarbon with conjugated double bonds which is capable of, and is in excess of the amount required for, forming a gummy product with the nitric oxide, compressing the gas, washing it with an oil which absorbs the unused hydrocarbon, and recycling the oil as a part-source of the initially added hydrocarbon. Cyclopentadiene is the hydrocarbon preferably used; butadiene and indene are referred to as unsuitable. The oil used may be a coal tar oil (sp. gr. about 1.1, distilling range 200-300 C.) or a petroleum fraction (sp. gr. about 0.88, distilling range 300-370 C.). As shown, coke oven gas at atmospheric pressure, to which some cyclopentadiene has been added, is admitted to a washer 2 through a pipe 1 and is washed therein by oil containing cyclopentadiene from the previous cycle. The gas takes cyclopentadiene from the oil and is then compressed to about 14 atmospheres in a compressor 3 and delivered to a column 4 down which the oil, removed from the washer 2 by a pump 6, is passed. In the column 4 the gas gives up the hydrocarbon, and gummy reaction products thereof with nitric oxide, to the oil, which is recycled, the gas passing out at 5. The washing is carried out at about 25-35 C. In a modification the oil delivered from the base of washer 2 is passed to a distillation column for removal of benzene, some then being pumped to column 4 and the remainder recycled direct to column 2.

Title: Improvements in or relating to electrical supply systems
IPC: H02P9/30
Filed: 1959-09-08
Abstract: 966,292. Automatic voltage control. SIMMS MOTOR UNITS Ltd; E. L. ROBINSON, and R. H. SHIMWELL. Sept. 8, 1960 [Sept. 8, 1959], No. 30670/59. Heading G3R. Parallel-connected transistors T2 T3 in the field circuit of a variable speed generator G are rendered conductive when the generator starts up and produces current by virtue of its residual magnetism, so that self-energizing current flows through the field F1. At a predetermined voltage a Zener diode Z2 connected as shown becomes conductive to protect the transistors T2, T3 by providing a by-pass circuit for the transistors. As the generator output continues to increase, the voltage across another Zener diode Z1 causes that diode to conduct and apply a negative potential to the base of a transistor T1 the collector of which is connected to the bases of transistors T2 and T3. Transistor T1 thus becomes conducting at a voltage determined by the Zener diode Z1 and causes transistors T2 and T3 to switch off whereby the energizing-current through F1 is decreased and the generator output is reduced; Z1 then becomes non-conducting and T1 is switched off so that T2 and T3 again become conducting. The generator output thus again increases until Zener diode Z1 conducts and the field current is interrupted. The output of the generator is thereby maintained substantially constant, and the current in the field winding is substantially independent of generator output voltage between the valves at which the Zener diodes Z1 and Z2 conduct.

Title: Apparatus for detecting or measuring beams of high energy charged particles
IPC: H05H7/00
Filed: 1962-08-10
Abstract: 959, 247. Measuring radiation. CSF-COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Aug. 10, 1962 [Sept. 7, 1961], No. 30726/62. Heading G1A. The intensity of a beam 2 of high energy particles propagated through a duct or guide 1 is measured by an ionization chamber 3 comprising a metallic casing 5 inserted into the duct and closed by an insulating cover 4 through which a conductive probe 7 extends into the chamber. The ionization produced in the latter, (filled with a gas, which may be air), is believed to be caused by particles from the peripheral zones of the beam and the current through galvanometer 9 (which may be calibrated in terms of beam intensity) is therefore a function of both the proximity and intensity of the beam. In Fig. 2, which shows a modification of the arrangement, the ionization chamber 5 is formed as a toroid the probe 7 in this case communicating with a metallic ring 20 which forms one electrode of the chamber. With this arrangement the reading of galvanometer 9 is independent of small departures of the beam from the central axial position. Fig.4 shows a further arrangement in which opposite pairs of ionization chambers 3 symmetrically positioned with respect to the beam are differentially connected to an indicator, the position of intersection of the needles of which is a function of the position of the beam relative to the axis of the guide. Fig. 5, shows an application of the invention to a pulsed accelerator in which a particle beam 101 is dispersed by an electromagnet 102 in accordance with the energy of the particles to produce a beam (of known energy) within a band determined by slot 104. Five ionization chambers of the kind described in connection with Fig.1, are inserted into the duct and their probe electrodes connected to difference taps on a delay line 106 the output of which produces the vertical deflection of an oscilloscope 107. The horizontal deflection of the latter (timebase) is affected at the same recurrence frequency as that of the accelerator pulsing and the total delay of line 106 is made slightly less than the period of this pulsing. In this manner an image of the energy spectrum of the accelerator is displayed and may be employed to facilitate adjustment of the latter.

Title: Improvements in or relating to fountain pens
IPC: B43K5/04
Filed: 1932-11-02
Abstract: 401,105. Fountain pens. GODEK, B. A., 86, Rue de la FÚdÚration, Paris. Nov. 2, 1932, Nos. 30846 and 30847. Convention dates, Nov. 7, 1931, and Sept. 15, 1932. [Class 146 (iii).] A fountain pen is provided with a supplementary ink reservoir at the rear of the main reservoir, the supplementary reservoir being provided with means for ejecting the ink into the main reservoir and with self-filling mechanism acting also to fill the main reservoir. The pen comprises a barrel a provided with a plug b frictionally mounted intermediate its ends, the plug being bored with a small aperture j and carrying a collapsable sac reservoir g which is secured in place by a ring i. A cross-piece l obstructs the outlet of the aperture j into the main reservoir m so that when the ink from the reservoir g is expelled it will not be forced through the passages in the feed-bar c. To fill the pen, the sac is deflated and allowed to expand, resulting in the filling of the reservoir m. The pen is then inverted and the sac again deflated to expel the air which passes through the ink in the reservoir m and escapes through the feed-bar passages. The nib is again inserted in ink and the sac allowed to expand. The sac may be deflated by any usual mechanism such as a lever pivoted in the barrel, the lever being preferably provided with a resilient projection or bosses to arrest the return of the lever slightly short of its normal position so that, when the nib has been withdrawn from the ink after filling the reservoir m, the lever can be returned to normal position to produce additional suction and draw the ink from the feed-bar passages, thus preventing its ejection when the sac is again deflated to fill the supplementary reservoir. In a modification, the sac is provided with a flexible reinforcing ring at its mouth, and a plug, bored longitudinally to form the aperture j, and transversely to form the obstruction l is inserted. The Specification as open to inspection under Sect. 91 describes also a plug for effecting the self-filling operation, the plug being provided with a lateral projection normally lying in a recess in the barrel but adapted to be turned to engage the wall of the barrel and prevent the return of the plug to normal position. This subject-matter does not appear in the Specification as accepted.

Title: Process for charging catalysts into reactors
IPC: B01J8/00
Filed: 1953-11-09
Abstract: In charging a catalyst into a tubular reactor, dust and undersize particles are removed by passing the catalyst over a sieve provided in a casing, the cross-sectional area of the inlet to the casing being from 0.8 to 0.1 times that of the outlet through which the coarse particles pass from the casing into the reactor; during charging, a stream of gas, e.g. carbon dioxide or nitrogen, is passed through the casing at a rate sufficient to loosen the catalyst mass but insufficient to cause any turbulence.  The catalyst may be reduced precipitated iron, nickel, or cobalt of grain size in the unreduced state 0.5 to 7 mm. used in the hydrogenation of carbon monoxide to form hydrocarbons and oxygen-containing organic compounds.  The catalyst may be unsupported or supported on kieselguhr, activated bleaching earth, or alumina.  Reaction tubes 10-20 meters long may be charged.  Catalyst remaining on the upper tube plate is removed by suction in a stream of inert gas.  To reduce formation of dust during charging, the tubes may contain liquid, e.g. synthetic hydrocarbon.  Various constructions of sieves are described (see Group II).
