Title: Radiation beam deflection
IPC: H05H1/00
Filed: 1966-06-02
Abstract: 1,142,957. Light deflectors. INTERNATIONAL BUSINESS MACHINES CORP. 2 June, 1966 [7 June, 1965], No. 24606/66. Heading H4F. A collimated beam of monochromatic preferably circularly polarized radiation 4, Fig. 1, is deflected by directing, e.g. by means of mirror M1, the beam along a path through an ionizable gas in a container, and by creating a magnetic field along the path having an intensity varying progressively across the plane perpendicular to the path by means of polepieces 12 and 14 of electromagnet 16, the gas being excited by means of a radio frequency electric field applied by means of conductive rings 6 and 8. Since the dispersion characteristic of the gas or plasma is a function of the magnetic field, variation in the strength of the magnetic field varies the refractive index of the gas and controlled angular deflection is accomplished. The ionizable gas may comprise Helium, Argon, Krypton or Xenon and is sealed under pressure in glass or quartz cylindrical container 2. The radiation beam may be emitted from a microwave, millimeter or optical maser. The polepieces of electromagnet 16 are shaped to provide a magnetic field with constant gradient between the upper and lower surfaces of container 2. It is arranged that the electrons gyrate in the ionized gas in the same sense as the beam is circularly polarized. If the incident beam is plane polarized its plane of polarization is rotated after passing through the gas. The actual deflection in the gas takes place due to the fact that each point on the wavefront travels at a different velocity. The deflection may be controlled by varying the magnetic field strength and/or the electron density. Solid bismuth which exhibits cyclotron frequency phenomena and is transparent to long wavelength radiation may be used to increase the electron densities.

Abstract: 263,557. Pearson, A. Oct. 3, 1925. Lamp signals; track apparatus actuating signals other than on trains; visual outdoor signals. - A device for giving warning to pedestrians &c of the approach of a train to a level crossing comprises a horizontal shaft 26 at the ends of which are carried arms 19, 20 preferably in the form of double-bladed canoe paddles. The arms are provided with lamps 56, and with rings 69 adapted to strike bells or gongs 7 mounted on a hollow column 1 at the top of which shaft 26 is disposed. The arms are mounted to rotate in opposite directions, and are arranged so that the lamps pass at the highest and lowest points, the rings 69 being disposed so that the gongs 7 are struck as the lamps pass each other. Rotation is effected from an encased motor 3 at the foot of the column, through a transmission shaft housed in the column and having bevel gear at top and bottom. The gear at the top, shown in plan, Fig. 6, comprises a wheel 13 on the vertical transmission shaft 12 meshing with gear wheels 16, 17 provided with bosses 23 which carry the arms 19, 20. The gearing is enclosed in a preferably two-part casing, and ball-bearings are provided where desirable throughout the transmission. Leather-faced cones mav be used instead of bevel wheels. The motor and lamps are normally de-energized, but are adapted to be energized in parallel on closure of the circuit by the armature of a normally de-energized relay, not shown, when the relay is energized. The relay is connected in series with a battery across two insulated rails extending to some distance at each side of the crossing, the relay circuit being closed when the rails are bridged by an approaching train. The circuit to the lamps is carried through wiper contacts co-operating with contact rings &c. on the bevel wheels. An arrangement is described using only one gong struck by both rings. Arrangeniemt may also be provided to give an alternative signal in case of failure of the main battery. For this purpose a hollow arm or casing 89 bearing transparencies showing the word " danger " is pivoted to the column 1 and is normally held in the vertical hidden position by a bolt 97 engaging a stud 93 on the post and pivoted to a pivoted arm 94 in the casing. A solenoid 91 in the casing is normally energized by the main battery to hold its com 100 raised. On failure of the main battery the core falls and strikes arm 94, releasing bolt 97 so that the arm 89 falls to the horizontal position shown in dotted lines, where it rests on a spring buffer 92a. At the same time a contact 98 on arm 94 engages a fixed contact 99 preparing a circuit from an auxiliary battery through lamps (not shown) within arm 89, in series with the insulated rails, so that the arm is illuminated by the passage of a train.
