Patent GB-473326-A (GB)
Title: Improvements in or relating to the coating of surfaces of iron or steel
IPC: F27D1/08
Filed: 1936-04-06
Abstract: An iron or steel surface is phosphatized by spraying thereon a dilute solution containing at least one acid phosphate, the solution being continuously sprayed on to each part of the surface with such force as to prevent the formation of any thin skin or film between the work and the solution or to break through any such skin or film that may already exist, and with such force that the surface is uniformly wetted, i.e. that the formation of small streams of solution running over the work beneath the spraying nozzles is avoided.  The spraying pressure may, if the spray is divided into small drops, be as low as 10 pounds per square inch, but a pressure of about 20 pounds is usually employed.  The solution must contain at least one phosphate which hydrolyses to produce free acid and which is non-oxidizable when sprayed through the air, e.g. an acid phosphate of manganese, zinc, cadmium, or calcium.  Sodium phosphate which does not hydrolyze may be used in conjunction with one or more of the hydrolyzable phosphates.  The acid ratio of the solution is preferably as high as 10 : 1, this ratio being preferably obtained by working at temperatures below the boiling point, e.g. 65-75 DEG  C., and by adding nitrates as accelerating agents.  Copper compounds may also be added to accelerate the reaction and give a harder coating, e.g. the solution may comprise zinc dihydrogen phosphate, sodium nitrate, copper carbonate, and water.  The solution is preferably replenished with liquid containing nitric acid as described in Specification 473,974.  British Specifications 390,834, 397,179, and 473,285, and U.S.A.  Specifications 1,869,121 and 1,872,507 also are referred to.

Abstract: 187,081. Munro, H. Aug. 22, 1921. Cooking-stoves; air supply for combustion. - In gas - heated oven stoves for cooking &c. air is admitted under the burners only, the air orifices, which direct the current upwards and across the flame, being formed between the burners and removable plates, entrance, of air otherwise than through the orifices being prevented by the burners making contact with the removable plates or with the walls of the stove. In the stoves shown in Figs. 1 and 4, the bottom of the oven is closed by a plate 1, the burner pipes 2 being arranged in chambers 4 open to the, air and separated from the interior of the oven by removable plates 6 having openings into which project the elongated burners 3 so as to leave an air orifice 7<a> between the lower edge of the burner and the upper edge of the opening in the plate 6. Entrance of air above the burner is prevented by the upper face of the burner making contact with the top of the opening in the plate 6. Inclined recesses 3a formed between the orifices of the burner give the air an upward direction, and the lower edge of the orifice 7a in the plate 6 may be set at an angle for the same purpose, as shown on the right-hand side of Fig. 1. Various arrangements of the plates 6 and of the end and top walls of the burner chambers 4 are described. In the form shown in Fig. 6, an angle-plate 61 forms the inner and top walls, the air orifice 7d being formed between it and the burner pipe 2 which it carries. The bottom plate 1 may be dished as shown in Fig. 1 to assist the heated air beneath it to flow into the burner chambers 4; this flow may be further assisted by depending guide-plates 15 at the sides, beneath which is a plate 18 with a central port 19 for the entrance of air. Fig. 3 shows a modification in which a removable tray 14 closes the bottom of the stove, the air orifices 7<b>, 7<c> being formed between the sides 6e, 6k of the tray and the burners 3. The waste, gases pass away through a port 8, Fig. 4, the inner edge 9 of which is at a higher level than the outer edge 10. An exhaust flue 11 may be used instead of, or in addition to, this port.

Title: Improvements in automatic control mechanism for the power plant of ships
Filed: 1945-09-03
Abstract: 602,754. Electric control systems for marine engines. TREASURE, W. S. Sept. 3, 1945, No. 22641. [Class 40 (i)] The output of a ship's power plant is reduced, when the depth of immersion of the propeller falls below a datum value, by means of a pressure chamber, in communication with the sea below the low-water level of the ship, which operates a pressure-controlled relay, thereby actuating the power plant controlling means. As shown, the butterfly valve 2, which controls the supply of working fluid to engine 1, is operated by the electrically energized thruster 4, of standard form, through link 3. Thruster 4 is energized through relay 5, comprising manually-controlled switch 8 and a solenoid 7 which is energized through a fluid pressureoperated switch 6, connected by a tubular conduit 18 to a pressure chamber mounted on the hull, below the low-water mark. The conduit 18 is oil-filled up to a point adjacent to the pressure control switch 6, the expansible bellows of which are air filled. A reduction in the propeller immersion depth below a minimum, and beyond which the propeller would overspeed, cause the energization of the thruster 4 and a reduction of power to the prime mover, through valve 2, which is returned to the normal setting, by the thruster restoring springs, when the propeller again moves below the minimum depth. The device is unaffected by an increase in the propeller depth beyond the minimum and the butterfly valve may be operated manually by closure of switch 8.
