Title: Improvements in and relating to methods and apparatus for increasing transmutation efficiency of nuclear reactions and converting nuclear energy into power
IPC: G21G1/10
Filed: 1947-08-27
Abstract: 656,398. Positive ion tubes. LUCAS, S. H. Aug. 27, 1947, No. 23642. [Classes 39 (i) and 39 (iv)] A method of performing transmutation reactions between atomic nuclei comprises injecting into an evacuated vessel a stream of positive ions, some of which have a different injection velocity from the others, introducing into the ion stream free electrons to counteract electrostatic repulsive forces, and subjecting the ions to a controlling magnetic field to constrain the ions to move in closed orbital paths; the paths have at least a part in common which is traversed concurrently by ions of different injection velocities. There may be two streams of ions, the ratio of the total masses of the two streams lying between 10<SP>6</SP> : 1 and 10<SP>-6</SP>: 1, and preferably between 10: 1 and 1: 10. The ratio may be controlled either by varying the injection rate or by varying the duration of injection. The magnetic fields may be arranged as in Fig. 3 with two solenoids W to pass the ions over the straight parts of their orbits and two magnets C<SP>1</SP>, C<SP>2</SP> to provide turning fields. The polepieces of the magnets C<SP>1</SP>, C<SP>2</SP> may be wedge-shaped to provide a field which varies as the inverse nth power of the distance from the edge of the polepieces adjacent the solenoids, where n lies between 0 and 1. Ions of the same charge will have identical orbits if their momenta are equal; T<SP>1</SP>, T<SP>2</SP> show typical orbits of ions with different momenta. Injection of the ions may take place at any of the points S<SP>1</SP>, S<SP>2</SP>, S<SP>3</SP>, S<SP>6</SP> or S<SP>5</SP> according to their energy and charge. The reaction chamber may be provided with cooling fins, and if neutrons are generated by the reaction the chamber may be constructed of beryllium or may have a lining of beryllium to slow down the neutrons. Outside the beryllium layer there is provided a further layer of an alloy or compound of boron, lithium or cadmium to absorb the neutrons. Alternatively a fissionable material such as uranium may be used as a lining for the chamber. The apparatus may be used for the reaction 2 1 D+2 1 D=3 2 He+1 on .

Convention date, Aug. 26, 1930. [Class 40 (iii).] In a television system in which a scanning beam is focused at the position of a moving scanning disc, a light-reflecting arrangement, rotating with the scanning disc, directs the light to or from the apertures of the scanning disc. In a receiving system, Fig. 1, the light beam from a variable source 30 is converged by a lens 31 towards successive mirrors 20 individually mounted on a rotated drum or wheel so that each mirror brings the beam to a focus in the plane of a disc 10 with apertures arranged in a 'spiral or a circle and mounted on the shaft 11 of the mirror member. Each mirror is arranged so that the points at which the beam is brought to a focus by the individual mirrors coincide with the individual apertures and pass across the scanning field delimited by the opening 15 of a screen 14. The successive lines are projected by a lens 32 on to a viewing screen 40 which may be of ground glass or the image may be viewed directly at the screen 14. When the apertures of the disc 10 are arranged in a circle an additional disc carrying lenses is rotated with the aperture disc to effect the scanning movement in a direction perpendicular to the paths of the apertures. The beam may be arranged to cover two or more mirrors 20 simultaneously as illustrated in Fig. 2. In the system as applied at the transmitting station, Fig. 4 (not shown), the lamp 30 is replaced by a constant light source of great intensity and the light beam focused by a mirror on the corresponding aperture passes through or is reflected from the picture, corresponding to the screen 40, to one or more photo-electric cells. For the recording of television images on a moving film, the apertures of the disc 10 are arranged in a circle, and the screen 40 is replaced by the film which is moved uniformly and continuously. The mirror system may be arranged with the mirrors inclined away from the scanning disc and enclosing the light source 30.

Abstract: 501,145. Polymerizing olefines. STANDARD OIL DEVELOPMENT CO. Sept. 2, 1937, No. 24038. Convention date, Oct. 24, 1936. [Class 2 (iii ] The polymerization of normally gaseous olefines to motor fuels is effected'by forcing a liquefied olefine mixture into the lower part of a sulphuric acid bath at polymerizing strength and temperature through a plurality of jets of diameter between À015 and À10 inch with a velocity at the jet throats of at least 40 ft. /sec., the jets being at least 6, preferably 10 to 12 ins. apart, and at least 4, preferably at least 6 ins. from the side walls of the vessel, so that the olefine is dispersed in small drops which rise through the acid, the height of which is between 3 and 12 ft. when measured in the quiescent state, and is adapted to provide time for substantial reaction, the hydrocarbons then being separated from acid and the polymer recovered. In a modification, a single jet of the same diameter is used and a reaction vessel of 6-12 ins. diameter. 50-80 per cent acid is generally used ; at about 70-150‹ F. for polymerizing only iso-olefines, e.g. isobutene; about 200-300‹ F. for copolymerizing isobutene with straight chain olefines ; or about 300-500‹ F. for non-selective polymerization. The liquefied olefines are forced through filters 3 or 4 and from jets 7 arranged in the acid chamber 6 as shown in Fig. 2. The jets may be replaceable and shaped as shown in Fig. 3. In a modification, they are directed downwardly against a plate or the base of the chamber which reverses the flow of the hydrocarbon stream and breaks, it into drops. Hydrocarbons and entrained acid are carried over by pipe 9, fitted with a cooling jet, to separation vessel 9a, the lower acid layer being returned and the polymer layer passed to a cooler 10 and separator 11. Any acid present is allowed to settle out and recirculated by line 12, the polymer layer then being led through cooler 15 to vessel 16. Any gases are vented by lines 17, 18. Part of the product may be recirculated by line 19 and pump 20 to increase copolymerization of iso- and n-butenes and polymerization of n-butenes. In examples, figures for the feed rate, jet velocity and yield are given for the polymerization of a mixture of isobutene and excess of n-butenes with 60 per cent acid at 225‹ F. using various jet sizes and acid heights. The polymerization of nbutene under similar conditions, and of a mixture containing propene, iso- and n-butenes with 66 per cent acid at 200‹ F. also is described.
