Abstract: 286,394. Adcock, F. Dec. 18, 1926. Drawings to Specification. Anti-dazzle screens.-In an anti-dazzle arrangement for use in connection with vehicle and other lamps, and particularly for use in fog, all light emitted by lamps within a given region is plane polarized in a pre-arranged direction, and all observations are made through windows in the form of analyzers adapted to pass the maximum amount of light polarized in a direction at rightangles to the first direction and which pass practically no light polarized in the first direction. These two directions are defined in respect of the directions of the beams and a horizontal plane, and do not vary according to the position of the vehicle within the region. Any direction, other than 45‹ to the vertical, may be employed, the efficiency increasing progressively from these two directions towards the horizontal and vertical. A pile of thin plates of glass, celluloid, or other transparent isotropic substance, arranged parallel to each other and at a suitable angle to the direction of the beam, or Iceland Spar, or other doublyrefracting substance, may be used to polarize the light by refraction or reflection, dull black surfaces or other means being provided to absorb respectively the reflected or refracted rays.

The pipe 11 is formed with a wide mouth 15 in the generator or the part 13 of the pipe is otherwise constricted and enlarged to secure a strong liquid column during the sealing period. In operation, assuming the liquid in the vessels 1, 2, and 6 to start at the common level x, the heating of the generator forces the liquid down the pipes 10, 21 and up the pipe 13, and when the liquid reaches the level of the cup 15 liquid columns will remain in the pipes 10, 13 and a flow will be produced in the pipe 21 to the absorber. When the level has sunk to the bottom of the bend 14 gas will flow through the pipe 11 and force the liquid from the pipe into the chamber 2 and thus equalize the pressures again. Strong liquor will commence to flow from the chamber 2 through the pipe 8, 10 and the cycle will be repeated. The absorber 6 and chamber 2 are both above the level of the generator and the pipes 10 and 13 are both of greater length than the lift of liquid in the pipe 22. The upper part of the chamber 2 may serve as a rectifier and the pipes 22, 24 may be formed as an interchanger.

Abstract: 736,107. Electrolytically depositing nickel. WILMOT-BREEDEN, Ltd. July 6, 1953 [Dec. 24, 1952], No. 32721/52. Class 41. In a process for the electrodeposition of nickel an asymmetric alternating current is used which is rendered asymmetrical by means including a rectifier and a resistance arranged in parallel, the larger half-wave effecting the deposition and the smaller removing a part of the deposit. An anode b is connected to a transformer a by a circuit containing two branches in parallel. One branch includes a rectifier d, and the other includes an oppositely acting rectifier e in series with a variable resistance f. A variable resistance g is in series with both branches ; h, an article to be plated, is connected directly to the transformer a. The half-wave which deposits nickel passes through rectifier d, and the half-wave which partially removes nickel passes through rectifier e, the value of this latter half-wave being determined by resistance f. Best results are obtained if the bath contains a trace of copper.
