Abstract: 669,457. Luminescent materials. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 30, 1950 [Feb. 4, 1949], No. 2385/50. Class 39 (i). A phosphor comprises ingredients with the range: alumina 1 mol., lithia 0.1-0.75 mol., silica 0-0.4 mol. and ferric oxide 0.0004- 0.016 mol., prepared by heating together aluminium hydroxide, lithium carbonate, hydrated silica and ferric hydroxide. Alternatively carbonates, nitrates or salts of organic acids may be used. Firing is at 1100- 1400‹ C. for from one minute to twelve hours, according to the batch. Leaching of the phosphor with hot water or hydrochloric or benzoic acid for several days is necessary to remove lithia from the surface of the phosphor, to prevent curdling of the nitrocellulose binder and improve efficiency. The phosphor is reheated to drive off water. Lithium may be replaced by sodium, potassium or calcium but these compounds give unsatisfactory luminescence.

Abstract: 361,193. Protective cut-out systems. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Webb, R. L. ; 1310, Beverly Road, Brooklyn, New York, U.S.A.) Jan. 30, 1931, No. 3062. Convention date, Jan. 30, 1930. [Class 38 (v).] For interrupting a circuit when the power is in the reverse direction a circuit-breaker is actuated by a relay energized in accordance with the power of the circuit and its direction, and a restraining effect dependent on two different voltages of the circuit and the phase angle between them is applied to the relay so that it will operate the circuitbreaker only when there is a true fault, and not when regeneration or surges occur. Feeders 7, 8, 9 are disconnected from a network 11 bv a circuitbreaker 10 when the power is from the network to the feeders by means of a three-phase induction disc power directional relay 18. Associated with each disc 20, 21, 22 are windings 23, 24 energized in accordance with the current in the feeders and the voltage to earth respectively. When the power is in the proper direction the relay is urged in the direction of the arrow 29 so that contacts C are closed, and the circuit-breaker closing coil 13 is energized. If the power reverses, the relay moves in the opposite direction and contacts T are closed to energize the circuit-breaker tripping coil 12. In order to prevent the opening of the circuitbreaker unless there is a true fault, the disc 20 has associated with it, two additional windings 36, 37 energized in accordance with the voltages 9-8 and 8-7 respectively, a resistance 38 being included in the circuit of one of them. The effect of these windings is to urge the relay in the direction of the arrow 29, so that unless there is a true fault, the relay is biased sufficiently to prevent the tripping of the circuit-breaker. If a true fault occurs, the bias is correspondingly reduced and the circuitbreaker is tripped. A spring 33 also urges the relay to close the contacts C, and the current windings 23 are connected across the contacts of the circuit-breaker 10 through ballistic resistances 31, so that after a fault is removed, the circuit-breaker is reclosed. In Fig. 2 (not shown) the windings 36, 37 are each replaced by two additive windings energized in accordance with the voltage of two of the feeder lines to earth. In Fig. 4 (not shown) the windings 36, 37 are each energized in accordance with the voltage of a feeder line to earth, so that the relay operates for both interphase and earth faults.
