Patent GB-388454-A (GB)
Title: Improvements in or relating to protective gear for alternating current systems
IPC: H02H3/28
Filed: 1931-09-11
Abstract: 388,454. Protective cut-out systems. ROSS, T. W., 10, Broadoaks Road, Sale, Cheshire, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. Sept. 11, 1931, No. 25585. [Class 38 (v).] Protection of bus-bars S to which incoming or outgoing lines A, B, C or generators or transformers are connected is afforded by means of an induction relay, as 2a, associated with, and controlling the connection of, each line. Each relay has a field winding 3a energized by current transformers 6a in its particular line so as to be responsive to residual current in that line, and an operating winding 4a connected across the secondary of an auxiliary transformer, the primary of which is in series with the field winding 3a. The secondaries of the auxiliary transformers 8a, 8b, 8c are connected in a closed pilot circuit P, in which normally no current flows, but on the occurrence of a fault on the bus-bars producing a residual current in one or more lines, the auxiliary transformer appropriate to that line or lines will energize all the operating windings 4a over the pilot circuit P, and the relays of which the field windings 3a receive residual current will cut out the appropriate lines. With an external fault the currents induced in the circuit P cancel one another out so that the relays do not operate. Preferably relays of the " Translay " type are used so as to provide restraint by means of their biasing windings on the field magnets, and prevent creeping. Turn ratios for the transformers 6a, 8a, &c. are given in the Specification, which refers also to the use of instrument transformers existing in the lines and to tappings for the auxiliary transformers. The invention is also described in its application to a duplicate bus-bar system, Fig. 2 (not shown), in which two sources and four lines are selectively connectable to the bus-bars and each has a protective arrangement similar to that of each line of Fig. 1. In order, however, to meet the case where different lines &c. may be connected to different busbars, the pilot circuit is duplicated, each pilot circuit being associated with its own bus-bar, and tha connection of the auxiliary transformers thereto is dependent on the position of the selector switch of the line pertaining to that transformer. In addition, the bus-bar-coupler circuit-breaker is provided on either side with a similar protective arrangement so as to be included in the protected area.

Patent GB-258228-A (GB)
IPC: C03B7/08
Abstract: 258,228. Tucker, O. M., Reeves, W. A., and Beatty, J. M., (trading as Tucker, Reeves, & Beatty). Sept. 14, 1925, [Convention date]. Delivering molten metal.-Relates to a glassfeeding device off the kind in which a column of glass, emerging from an outlet in the floor of a forehearth, is supported and reheated, after a " gob " has been cut off, by the pressure of gases burning in a cup which is brought up beneath the outlet. According to the present invention, the combustible gas mixture is not introduced into the cup itself but into an annular burner which surrounds the outlet and diverts the flames downwards into the cup as it is brought up to the outlet. The flames also surround the emerging column of glass, when the cup is removed, and by remelting the surface eliminate scratches and defects produced by contact between the glass and the bushing. The outlet 4, Fig. 5, is formed in a replaceable bushing 3 which fits below an aperture in the forehearth 1 and is held in place by the annular burner 5. The burner is formed with a hollow annular compartment 6 which is fed with gas and air under pressure through a pipe 7 and is pierced with holes 8. These holes are formed at such an angle as to direct the continuous annular flame downwardly against the column of glass as it emerges from the outlet 4. After a " gob " of glass has been cut off the column, by means of shear blades 10, a cup 13 is swung upwards against the outlet, as shown in Fig. 12. The flames from the jets 8 are then enclosed by the cup, and the cushion of gases thus burning under pressure in the cup either retards, stops, or reverses the flow of glass through the outlet until the cup is removed. A baffle 16, Fig. 5, is fitted within the compartment 6 of the burner ring, opposite the inlet pipe 7, to secure an even supply of combustible mixture at all of the holes 8. The supply of gas and air may be reduced when the shear blades 10 are cutting the column of metal. In the construction shown in Fig. 12, the cup 13 is brought close to, but not in contact with, the underside of the bushing 3, and the burnt gases escape through the space between the cup and the bushing. In a modification, the cup is brought into contact with the bushing and the gases escape through a valve in the wall of the cup. In another modification, the gases escape through outlet ports formed in the ring 5. The glass may flow through the outlet 4 by gravity, or it may be extruded by fluid pressure or by the movements of a plunger reciprocating vertically over the outlet. The cup 13 and the shears 10 are operated by compressed air cylinders, and the admission of air to the cylinders is controlled by a timing device as described in Specification 208,172. Gas and air for the burner 5 are mixed and controlled by an injector as described in Specification 121,971. [Class 75 (i), Burners &c.].
