Abstract: 541,237. Gas-blast switches. REYROLLE & CO., Ltd., A., and AMER, D. F. April 15, 1940. No. 6785. [Class 38 (v)] Switches employing an arc-quenching blast of gas, which may be externally produced and/or evolved by the arc from solid material and directed laterally or axially with respect to the direct arc-path between the contacts, have a cooling and de-ionizing unit which comprises a casing adapted to be connected to the switchcasing and housing a hollow insulator in which is a restricted aperture through which the gases are discharged into it. As applied to a switch incorporating features of Specification 536,451, the insulator G is carried by an earthed metal flange F, F<SP>1</SP> which is bolted at F<SP>3</SP> to the metal casing D<SP>1</SP> of the insulating housing D, the bolts serving also to secure a metal casing E provided with an insulating lining E<SP>3</SP> and discharge outlets E<SP>2</SP>. The casing E may be earthed, but is preferably insulated by the washer F<SP>2</SP> and bolt-shroud F<SP>4</SP>. The conical upper end of G may be spaced from housing D for the purpose stated in Specification 541,236, and carries a nozzle G<SP>1</SP> which may carry or be in contact with the arcing tips B<SP>1</SP>, C<SP>2</SP>. The lower end of G carries a conical perforated wall J and a cylindrical metal wall H to which is attached a further conical perforated wall K, the space between J, K being filled with metal packing, such as tubing, of copper or other metal of high heat and electric conductivity. Concentric metal tubes L also surround wall H, but in a modification, Fig. 5 (not shown), a metal spiral may be located in the cylindrical part of G with its outer edge engaging the latter and its inner edge anchored to the rod N which, in this form, extends into the upper conical part of G and carries an auxiliary electrode, for the purpose described in Specification 541,235. The insulator of Fig. 6 (not shown) is itself formed with a nozzle and carries a metal grid which is earthed through a resistance.

Abstract: 575,824. Uniting metal to glass. STANDARD TELEPHONES & CABLES, LTD., and WINGENT, T. W. April 13, 1944, No. 6814. [Class 36] A metal-to-glass seal is effected by pouring molten glass around the metal element assembled in a mould and bringing a tubular glass element into contact with the molten glass surrounding the metal element. The molten glass may be injected into the mould which may be provided with suction-ducts. Figs. 1 and 3 show apparatus for uniting a glass tube 5 to a copper tube 1 comprising a metal or steatite annulus 2 and a plug 3 profiled to provide an annular cavity into which the molten glass is poured &c. so as to envelope the edge of the heated tube 1. The previously-softened end of the glass tube 5 is then lowered on to the molten glass, the composite structure being then allowed to cool and annealed in the ordinary way. To facilitate removal, the annulus 2 may be formed in halves hinged together and fitted with handles 8. The annulus 2 may be adjustably supported on a stand 7 which also carries a bearing 9 for guiding the stem of the plug 3 which is forced upwards. to consolidate the seal, by means of a pivoted lever 10. Fig. 6 shows a mould device for sealing the elements of a large vacuum tube 16 with an exhaust tube 17 and a series of conductors 15. The latter are assembled in a die 11 through which the plug 13 is adjustably mounted. The outer mould-member 14 corresponds to the annulus 2 of Figs. 1 and 3.

Abstract: 104,278. McAlpine, T. M. May 29, 1916. Tunnels.-Large tunnels are constructed by excavating separated sections of the space to be occupied by the tunnel arch, filling the excavated sections with concrete or other suitable material, and excavating and filling the intermediate sections before the core of the tunnel is removed. As shown in Fig. 1, headings are driven in sections c of the space to be occupied by the tunnel arch, each pair of sections c being separated by one or more similar sections. These headings are then filled in with concrete, &c., after which the intermediate sections are similarly excavated and filled in. The side walls and floor of the tunnel may be similarly constructed. The core e is then removed. The headings may be connected by lateral cuttings. The concrete &c. may be reinforced, and such reinforcement may extend into the adjacent sections so as to connect with the concrete subsequently inserted in these sections. In the form shown in Fig. 3, headings g are formed extending into the core e. Separated headings are widened on one or both sides in the arch space, and these widenings are filled in, leaving an open space which permits excavation of a heading to proceed simultaneously with the widening and filling. Adjoining headings are then treated. Widening and filling of adjacent headings, and removal of the core, may be carried on simultaneously but at different longitudinal parts, and widening and filling of longitudinally separated parts of the same heading may also be carried on simultaneously.
