Title: Improvements in or relating to electric alternating current circuit breakers
IPC: H01H33/18
Filed: 1932-03-01
Abstract: 398,207. High-tension switches; arcrupturing in switches. WHITNEY, W. B., WEDMORE, E. B., and BRITISH ELEC-, TRICAL & ALLIED INDUSTRIES RESEARCH ASSOCIATION, 36, Kingsway, London. March 1, 1932, Nos. 22721/33 and 22722/33. Divided on 398,213. [Class 38 (v).] A fluid-blast circuit-breaker has means for lengthening the arc close to, substantially parallel with, and alongside a conductor, for example a contact, and magnetizable material is arranged in said conductor whereby a field is produced which tends to force the arc against the conductor to counteract the effects of the arc-lengthening means and to minimize extension of the arc. The movable contact 19 is split at 38 to ensure resilient contact with the fixed contact 37, which is shaped so as to guide the fluid blast from the port 20 inwardly to the arc. The contact 19 is also engaged by a spring-pressed brush 18 mounted on a ring 15, both the latter and the contact 37 being provided with a peripheral groove into which is inserted a stack of soft iron plates 38a, which may be mutually insulated and U-shaped in plan, Fig. 2. The action of the plates is to resist the tendency of the fluid blast to bow the are formed between 19, 37 into the hollow contact 37 or the ring 15, by setting up a magnetic field which forces the arc against the side of the corresponding contact. In Fig. 3, the fixed contact 39 is a radially-split ring held by a spring 40, and an additional fixed contact 45, through which the movable contact 44 loosely passes, is carried on a cone 46 carrying fingers 48 as disclosed in Specification 398,249. The upper face of the cone 46 is segmented and provided with radial insulating inserts, as disclosed in Specification 398,213, and a conducting spiral 49 serves as a cooling grid. In opening, when the tip of contact 44 is below the top surface of 45, the arc is transferred thereto, but any tendency of the fluid blast to lengthen the arc, as described with reference to Fig. 1, is resisted by inserts 50, 51 of magnetic material. The distance between 45 and 39 is preferably substantially equal to the diameter of the outlets therein. The first Provisional Specification refers to Specifications 278,764, 330,616, [both in Class 38 (v), Electric switches &c.], 366,998, 375,309, and 378,493.

Title: Improvements in electro-magnetic overload cut-outs
IPC: H01H71/34
Filed: 1920-07-30
Abstract: 149,673. Krupp Akt.-Ges., F. Aug. 7, 1919, [Convention date]. Electro-magnetic switches for breaking circuit in case of overload are constructed with a series coil a<2> and two movable cores B and E restrained by springs C and F..The core B which carries the main current brush b<2> normally bridging across contacts D, D<1> is not attracted until the core E has been previously drawn a certain distance towards it, so decreasing the magnetic reluctance. The circuit is thus broken quickly and decidedly. In using the device with a motor not provided with a.starting rheostat, the springs and other parts are so dimensioned that the circuit is not opened by the temporary rush of current when the motor is switched in.

Abstract: 1517962 Moulding accommodation modules I F PRIMUS 6 June 1975 22909/75 Heading B5A An accommodation module having one open face is moulded between a core and outer form, the module being tilted after moulding to its "in use" position in which the open face is uppermost. As described in a first embodiment, a core and outer form are positioned on the horizontal leaf 21 of the table (positioned as in Fig. 3a), with the vertical leaf 22 forming part of the form. Concrete is cast and compacted to form the modules 50 with its open face down. The table is rotated through 90 degrees (Fig. 3b), the leaf 21 moved to a horizontal position (Fig. 3c) and the module 50 transferred to leaf 21 over leaf belts and rollers, after removing the core and outer form. The leaf 22 is moved to a vertical position (Fig. 3d), and the table is tilted through 90 degrees to place the open side of the module 50 upwards in its working position (Fig. 3e). In a second embodiment, the leaves 21, 22 are relatively fixed, and both leaves of the table are tilted to allow the module to be pushed on to a horizontal support that rotates about a vertical axis to turn the module 50 around before it is pushed back on to the table (Figs. 4b, 4c). Alternatively, two tables are placed side by side, with their adjacent leaves 20 intermeshing or aligning to allow the module to be tilted by either table (see Fig. 5, not reproduced). In another embodiment, the core is placed above a fixed-leaf table leaving a cavity, so that the module will be cast with its open face away from the leaves. The table is tilted so that leaf 21 is at 20 degrees to the horizontal, and a part 31 of the module is cast (Fig. 6b). The table is tilted to place leaf 22 horizontally (Fig. 6c) and the remainder 33 of the module is cast and screeded. The core can be rolled on wheels. All five walls of the module can alternatively be cast at once if the table is tilted about a post to raise the pivot axis of the leaves 21, 22 (Fig. 7, not reproduced). The core is hollow and comprises five walls and an open end. Reinforcing mats, bars making intermediate floors, and removable recess definers are connected together for earthing and supported on the core, which is mounted on a supporting frame movable on rollers between a reinforcing and a casting station.
