Title: Process and apparatus for the production of synthesis gases mainly consisting of mixtures of carbon monoxide and hydrogen and of hydrocarbons therefrom
IPC: C01B3/38
Filed: 1939-05-16
Abstract: 528,826. Gaseous mixtures. NAAMLOOZE VENNOOTSCHAP INTERNATIONALE HYDROGENEERINGS-OCTROOIEN MAATSCHAPPIJ. May 16, 1939, No. 14536. Convention date, May 18, 1938. [Class 55 (ii)] [Also in Group III] In the production of hydrocarbons from a synthesis gas mixture of carbon monoxide and hydrogen obtained by the conversion of gaseous hydrocarbons (natural gas) with carbon dioxide, at least part of the gases remaining after the synthesis and containing unreacted carbonmonoxide are oxidized to give carbon dioxide, which, after extraction, is re-cycled to the conversion of gaseous hydrocarbons. Nitrogen is also removed from the " tail gases. The hydrocarbons,for the production of the synthesis gas may also originate in coke oven gas, refinery gas &c. The hydrocarbon gas from a holder 1 is charged with CO 2  from a pipe-line 6 and supplied to a converter 5 containing a catalyst of nickel on clay at a temperature of 1100‹C. to form the synthesis gas mixture. From a cooler 11 the CO and H 2  mixture is passed to the synthesis chamber 10 at about 200‹C. Preferred catalysts herein comprise mixtures of Co, Th, and Kieselguhr; Ni, Mn, Al 2 O 3  and Kieselguhr; Co, Th, Cu, and Kieselguhr. Part of the unreacted gases is directed by a valve 21 to a heater 22 and from thence to an oxidizer 24 containing ferrite or iron oxide. Any hydrocarbons herein may be also oxidized to give CO 2  and H,O. The CO 2  is removed in a tower 26 by an absorbing liquor such as mono-ethanolamine aqueous solution, and the CO 2 -containing liquid is finally stripped in a tower 31, the CO, being re-cycled back to the converter 5.

Title: Improvements in means for amplifying and translating electrical impulses
IPC: H03K5/00
Filed: 1941-11-14
Abstract: 582,753. Wireless receiving systems. STANDARD TELEPHONES & CABLES, Ltd. (International Standard Electric Corporation). Nov. 14, 1941, No. 14669. [Class 40 (v)] The valves of a carrier-wave receiver are rendered intermittently operative by locallygenerated repetitive pulses of such amplitude that for the short duration of each pulse the valves deliver power in excess of their normal rating. As shown, the radio receiver of an obstacle detection system is of the superheterodyne type, and the H.F. amplifier 2 and frequency-changer 3 are brought into action intermittently by short pulses which are generated at 9 and are modified at 8 to render them suitable for controlling the plate potentials of the valves 2, 3. The generator 9 may be synchronized at 10 with the impulse generator of the transmitter, or it may be independent and controlled manually as to phase and frequency. The valves 2, 3 may be momentarily overloaded during the sensitizing impulses without the mean power dissipation exceeding their normal rating. The receiver gives an improved signal-to-noise ratio, and may be used for the reception of unmodulated or normally-modulated carrier waves. Specifications 511,222 and 582,752 are referred to.

Filed: 1947-06-09
Abstract: 625,883. Auxiliary propulsion means for pedal cycles. ALLEN-BOWDEN, Ltd., BOWDEN, B. G., and SAMPIETRO, A. C. June 9, 1947, No. 15101. [Class 79 (iii)] [Also in Group XXXVII] In a pedal cycle having a battery, a dynamotor which assists in propelling the cycle at low speeds and charges the battery at high speeds, the dynamotor comprises a stator winding and a coactor multi-polemagnet rotor fast with a sun wheel of a planetary gearing of which one of the wheel hubs of the cycle carries a planet wheel intermeshing the sun wheel and a stationary annulus. As shown a spindle 11 I is rotatable in unison with one of the wheel hubs and carries a planet carrier 12 with two gears 14, each meshing with a stationary internally toothed annnlus 15 and a sun gear 16 mounted on a shaft 17. The, shaft 17 is carried in bearings 19 of the stator and carries a non- magnetic disc 23 having secured to its periphery by teeth a magnetic ring 25 having twenty-four poles. The stator comprises a ring 28 having twenty-four poles with an appropriate winding 29. Secured to the stator casing 31, Fig. 3, is spring arm 36 of a change-over switching device. The spring arm 36 carries a follower 35 engaging a cam disc 34 whose high points are equal in number to the poles of the machine, the disc being carried on the shaft 17. When the disc 34 is rotated at low speeds, a contact 37 on the arm 36 makes alternate contacts between fixed contacts 38, 39 on the casing 31, but at comparatively high speeds of the disc 36 the contact 37 will not make with either contacts 38, 39 due to the resilience of the arm 36. Two changeover switching devices will be employed in practise working in synchronism with the electric system not earthed. With the electric circuit shown in Fig. 4, a control switch 41 in the position shown and the pedals propelling the cycle, the current generated in the winding 29 will charge the battery 33 through a rectifier 48. When the control switch 41 is moved to its other position in which contacts 42, 44 make with contacts 43, 45 respectively of the winding 29 and the cycle is travelling at low speeds, current from the battery 33 is alternated by the arms 36 and lead to the winding 29 causing the electric machine to act as a motor and assist in the propulsion of the cycle, but the change-over switching devices will operate as interrupters when the cycle has attained comparatively high speeds. A cut out may be provided to prevent over discharging of the battery 33.
