Patent GB-938597-A (GB)
Title: Electrode steam boilers
Inventor: WILLIAMS GERALD AUSTEN
IPC: F22B1/30
Filed: 1961-01-12
Abstract: 938,597. Electrode steam boilers. BASTIAN & ALLEN Ltd. Jan. 12,-1962 [Jan. 12, 1961], No. 1383/61. Class 39 (3). An electrode steam boiler, controlled by adjustment of the water level, has an open ended circulation tube positioned in the boiler with its upper end adjacent the lower end of one or more of the electrodes, and its lower end below the lower end of the electrode(s), whereby the resulting circulation of the water promotes a homogeneous distribution of the impurities present in the water. Circulation tube 17 extends below the three sector-shaped electrodes 15, which are vertically adjustable by means of the screwed rods 14 and are surrounded by the neutral shield 16. Heated water rises from the top of the tube 17, is directed on to the cooler shield and boiler wall, and thereafter sinks down outside the tube, which circulation is assisted by the admission of cold feed water via inlet 21, which is inclined in both the downward and tangential directions to stimulate a helical flow down the outside of the tube. This circulation promotes homogeneity, and the mixing of the cold feed water with water above the atmospheric boiling temperature induces deposition of scale-forming salts. As the water level is lowered consequent upon the steady rise in conductivity of the water, the resulting turbulence near the electrodes further assists circulation.

Title: Improvements in locking devices for levers controlling railway, tramway and similar signals and for other like purposes
IPC: B61L19/16
Filed: 1920-01-16
Abstract: 161,694. Downes, F., Cooke, C. J., and Rogers, W. D. Jan. 16, 1920. Hand.levers and hand gearing. -Hand-levers for railway and similar signals and points are locked by two suitably-shaped jaws pivoted to a bolt which is under the control of a member operated by an electromagnet. The frame 1 carries the electromagnet 2 at one end and is slotted at the other end 3 to permit movement of the lever 4. A bolt 8 slides in guides 9 and has pivots 6 carrying the locking jaws 5 which are slotted at 10 to pass over pins 11 on the frame. A pivoted locking member 12 is pushed by the overhanging bar 13 into a recess in the bolt, and depresses the lever 15 to withdraw the armature 16 from the electromagnet 2. To prevent the mechanism from being restored to the locking position unless the lever 4 is held by the jaws 5, one end of a lever 17 is pulled by a spring 19 across the slot 3 in the frame through which the hand-lever moves, and the other end is moved to hold the armature 16 against its magnet. When the electromagnet is energized, its armature is attracted and tends to lift the member 12, but is prevented from doing so by the bar 13. As, however, the lever is moved forwards, the bolt 8 follows under the action of the spring 19 and, owing to the shape of the slots 10 in the locking jaws 5, releases the lock upon the handle. The lock may be constructed with only one jaw instead of two.

Abstract: 431,787. Jet propulsion apparatus. WILD, P. H., 220, Ferrars Street, South Melbourne, Australia. Jan. 15, 1934, No. 1454. [Classes 113 (i) and 114] In a system for propelling, manoeuvring, steering, stabilizing, and lubricating the hulls of ships, air induced by the steam jet c, Fig. 2, is passed through the boiler a and the mixture of air and steam is directed down the conduit f and in subsequently passing up the upwardly and rearwardly directed conduit g gives by reaction a forward motion to the ship. A similar arrangement may be applied to the bows to enable the ship to be propelled astern. The discharge conduits g, l at the stem and forward may be duplicated port and starboard so that by controlling suitably the supply of propelling fluid through the various conduits and steering or manoeuvring of the vessel may be effected similarly by supplying the fluid alternately to the port or starboard conduits at suitable intervals the rolling of the ship may be modified. By supplying fluid alternately to the bow or stern, pitching may be quenched. The fluid may also be supplied to longitudinal underwater channels o to lubricate the hull. In a modification the discharge conduits are arranged in stages, the fluid carried off at the top of the first conduit v, Fig. 8, is supplied through the pipe y to the second conduit n.

Abstract: 843,010. Purifying liquids electrolytically. ELEKTROKEMISK A. S. Jan. 16, 1957 [June 19, 1956], No. 1706/57. Class 41. Waste water e.g. sewage, is electolytically purified by flowing it as catholyte above and in contact with an anolyte of greater specific gravity in a diaphragmless cell, both anolyte and catholyte being horizontal slow-moving turbulence-free streams. Typically a graphite anode 2 extends horizontally at the bottom of the cell so that the anolyte from passage 6 same plan area as the anode and is directly over it is a horizontal metal gas-permeable structure, e.g. a grid of steel wires or bars, while the anolyte-catholyte boundary surface C extends horizontally between anode and cathode, the control of its location being assisted by a weir B. The boundary surface C may be located just below the cathode 3 and the purified waste water may be discharged from the cell along conduit 9 either separately from the used anolyte which is drained off at A through a valve (not shown) or together with part or the whole of the used anolyte. Mud particles and occluded colloids are floated to the surface of the catholyte by the cathodically evolved hydrogen and are removed as by skimming. Preferably the anolyte comprises a magnesium containing solution e.g. sea water and sea water may also be added to the waste water to be purified, the boundary surface and current being so controlled that all the anodically evolved chlorine dissolves in the anolyte, and flocculent precipitates of magnesium hydroxide and magnesium phosphates formed assist in the removal of the mud and occluded colloids by the process of Specification 825,629.
