Title: Improvements in or relating to aerial systems for omni-directional radio range beacons
IPC: G01S1/02
Filed: 1947-04-15
Abstract: 634,201. Radio navigation ; aerials. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., PEAT, J. D., and WATSON, D. W. April 15, 1947, No. 10026. [Class 40 (vii)] An aerial system for use in a modulation phase radio beacon comprises a loop, or equivalent antenna, having a circular diagram and two dipoles in planes parallel.to that of the loop and equally spaced either side thereof, the dipoles being rotatable about a symmetrical axis perpendicular to the planes containing the aerial elements. The signals fed to the aerials of the system are such that the resultant dipole, and the loop or like, electric fields are cophasal. It is stated that with known aerial arrangements for beacons of this type the modulation depth of the signal received varies considerably with the elevational angle of the receiver with respect to the beacon. Experimental results are given showing that the modulation depth variation is relatively small for variations of elevation angle from 0 to 70 degrees with an aerial system according to the invention. The loop aerial may comprise cross-connected coplanar horizontal half loops 1 as shown, having a circular diagram with the horizontal dipoles 4, 5 and 6, 7 spaced equally above and below the loop. The spacing between the dipoles should be such that the vertical polar diagram in a plane at right angles to their length is similar to the cosine law diagram of the loop aerial The spacing may be adjustable for this purpose or may be made # of a wavelength. The modulation depth may be adjusted by altering the dipole lengths or by including amplitude varying circuits in the feeders to the aerial components. As the horizontal diagram of the loop is circular it may either be stationary or rotated with the dipoles as a single unit.

Patent GB-473285-A (GB)
Title: Improvements in or relating to the coating of surfaces of iron or steel
IPC: C23C22/76
Filed: 1936-04-06
Abstract: A cyclic process for phosphatizing iron or steel comprises spraying upon the metal with sufficient force to ensure thorough and uniform welting a dilute solution containing a phosphate or phosphates not readily oxidizable by spraying through air and a small amount of free acid, draining the solution from the surface, removing the sludge produced by the oxidation of ferrous phosphate and re-spraying the solution.  Ferrous phosphate is formed during the coating reaction and is oxidized when the solution is reflected from the surface in a state of subdivision.  The non-oxidizable phosphates may be one or more of the dihydrogen phosphates of manganese, zinc, cadmium, and calcium, or a mixture of one or more of these phosphates with sodium phosphate, and the spraying pressure is preferably about 20 pounds per square inch. Accelerating agents, e.g. nitrates or copper compounds, may be added to the solution, the acid ratio of which is preferably as high as 10 to 1.  The preferred spraying temperature is 65-75 DEG  C. To avoid sludge due to the hydrolysis of the non-oxidizable phosphates, a small amount of nitric acid is preferably added to the liquid used for replenishing the solution before re-spraying. For example a coating solution consisting of 350 lb. of sodium nitrate, 110 lb. of zinc dihydrogen phosphate, about 1 lb. of copper carbonate, and 2000 gallons of water may be replenished by addition of a solution containing 7,5 parts by weight of zinc dihydrogen phosphate, 1 part of 100 per cent nitric acid, and 0,4-0,5 per cent of copper carbonate, the nitric acid reacting with normal zinc phosphate formed by hydrolysis to produce zinc nitrate. Specifications 390,834, 397,179, 473,326, and 473,974, are referred to.

Title: Improvements in automatic telephone and the like systems
IPC: H01H67/06
Filed: 1920-04-13
Abstract: 165,971. Lambot, A. April 13, 1920. Automatic exchange apparatus.-In a selector of the type in which the line terminal contacts are arranged in horizontal and vertical rows on a semicylindrical casing within which revolves a shaft carrying brush-arms in number equal to that of the horizontal rows, the shaft is first rotated to bring all the arms opposite a given vertical row, a selected arm then being lowered to make contact between its brushes and a given set of contacts in this vertical row. During rotation of the shaft the brushes are out of engagement with the terminal contacts. The arms 4, Fig. 1, are pivoted to the shaft 3 at 5, and are held in a horizontal position, so that the brushes 6 are set above the contacts 2, by a tongue 9 which engages with a plate on a sleeve 7 slidably mounted on the shaft above a collar 8. The first of two sets of impulses operates ratchet mechanism to rotate the shaft until all the arms 4 are opposite a given vertical row of contacts. The second series of impulses selects and energizes a magnet 10, one of which is provided for each arm. The attraction of the armature 11 raises the sleeve 7, and, releasing the tongue 9, allows the brushes 6 to drop on the required contacts 2. At the end of a conversation the magnet 15 is actuated and lifts the ladder-like structure 17, the rungs of which pass beneath the arms 4 while permitting them to rotate. The " tripped " arm 4 is thus raised and the tongue 9 once more engages the sleeve 7. The magnet 10 is selected and actuated through the medium of a switch, Fig. 2. The second set of impulses energizes the magnet 29 which rotates the ratchet-wheel 27 and shaft 21 against the action of a spring 26. The arm 28 passes over contacts 19 each of which is connected to a magnet 10. The desired contact having been reached the solenoid 24 is energized, and attracting its core 23 lowers the shaft 21 and completes a circuit through the selected magnet 10 over the contacts 20, 25, shaft 21, arm 28, and contact 19. The shaft is restored by the springs 26 and 22 on the de-energization of the solenoid 24 and the release of the ratchet wheel 27 by the pawl 31, which is moved towards the interior or exterior of the wheel 27 by a relay (not shown). After the shaft has been restored to its normal position the pawl 31 moves through a notch in the wheel 27, under the action of a spring, to a position where it can again engage the teeth of the wheel.
