Title: Improved method of manufacturing magnet cores
IPC: H01F1/20
Filed: 1923-12-03
Abstract: 208,147. Felten & Guilleaume Carlswerk Akt.-Ges. Dec. 5, 1922, [Convention date]. Electromagnets.-Magnet cores' for inductance coils &c. are constructed of powdered iron alloy, such as silicon and nickel alloy, having a higher permeability than iron and compressed to a specific gravity of 5.5-6. The pressures used are about 3000-4000 kilograms per square centimetre, and the insulating material comprises 2-7 per cent of the iron alloy. The Specification, as open to inspection under Sect. 91 (3) (a), describes the use of phenol resins for insulating the alloy particles, the resins being rendered insoluble and infusible by heating. This subjact-matter does not appear in the Specification as accepted.

Patent GB-307836-A (GB)
Abstract: 307,836. Siemens & Halske Akt.- Ges. March 14, 1928, [Convention date]. Copying-telegraphs.-Two rotating parts, for example, the driving-shaft a and recording-drum g of telephotographic apparatus, which are to be coupled in predetermined phase-relationship, are brought into synchronism by a friction clutch and then automatically coupled positively by gravity or other force. The drum g, when placed on the vertical shaft a, rests on a spring-supported friction cone b, connected to the shaft by a pin c engaging one of the inclined grooves o in a collar d secured to the shaft. The weight and inertia of the drum, the strength of the spring e, and the grip of the clutch cone b are so calculated that the drag on the cone b maintains the pin c at the upper end of its groove o until the drum g has ceased accelerating. The drum then sinks, a pin h thereon being guided by an inclined surface e<1> into a slot k in the shaft a, a coned part a<1> of which supports the drum. The pins c, h may be carried by the shaft and the coacting parts by the cone b and drum g respectively. The shaft a may form part of a second drum, to which the drum g is to be clutched. The positive coupling may be effected by spring or magnetic force, in which case the shaft a need not he vertical.

Filed: 1926-12-07
Abstract: 262,777. Siemens - Schuckertwerke Ges.- Dec. 8,1925, [Convention date]. Electromagnetic switches; cut-out arrangements. - A discriminating reverse-current and overload switch for use at a, b, c, d, Fig. 2, to protect rotary converters g<1>, g<2>, rectifiers u<1>, u<2> &c. supplying the same bus-bar s in parallel has a switching period shorter with reverse current than with current of normal direction, the operating flux reaching the release point more quickly in the case of reverse current than with normal. The switch comprises a magnet structure with a coil g energized from a constant voltage, this coil alone being adequate to attract the armature h and break the main circuit at k<1>, k<2>. The magnet structure is provided also with a series coil f which with current in the normal direction opposes g. A heavy current in this direction is therefore necessary to overcome the action of the coil g and cause the operation of the switch, whereas at zero current or any reversal of current the switch opeates. The line element is furnished by the use of short-circuited bands on the core which retard the growth of the flux- Specification 240,453 is referred to.

A radial carcass ply P is laid on the drum with its edges P<SP>1</SP> overlying grooves 39, 40 in the elements 32, 33, the drum being rotated as needed, and the ply being supported on a diaphragm 67 in turn supported by lever arms 68, 69 and the elements 32, 33. Bead cores B are positioned over the ply in the region of the grooves. The shaft 11 is rotated while crossheads 19-19a, 20-20a are held stationary to cause ring members 41-44 to move apart along sleeves 15, 16 on the shaft which they screw threadedly engage causing cam rollers 49-52 on the cross-heads to ride along respective cam tracks 37a, 37b on the elements 32, 33 causing the latter to move radially outwards so that the bead cores enter the grooves 39, 40 until the ply is clamped between the bead cores and the elements 32, 33. Ply turn up is then effected by pusher bars (77, 78, Figs. 3 and 4, not shown) sliding in recesses (75, 76) in the elements 32, 33 beneath the edges P<SP>1</SP> to bend the ply and press the edges against the main portion of the ply where they are held by stitching. Shaping the cylindrical carcass to toroidal form is accomplished by push-pull means connected to tie rods (26), 27 which move the cross heads 19- 19a, 20-20a towards each other, as shown in Fig. 5, causing lever arms 68, 69 to pivot radially outwards and assist in the expansion of the diaphragm 67 and carcass ply material P. Simultaneously compressed air is admitted via bores 13, 13a in the shaft 11 to the interior of the diaphragm, the air being retained by bellshaped ends 87, 88 telescoped over the drum ends to seal against the bead regions.

Yarns, threads &c., treating with liquids, gases and vapours.-The extensibility and elasticity of artificial silk &c. yarns and threads is increased by treatment with alkali and carbon disulphide in either order or simultaneously under such conditions that xanthogenation to a limited degree is produced, the materials being maintained in the untensioned condition during the treatment or if tensioned the tension being removed preferably before the material leaves the alkali bath so that shrinkage may take place. After the treatment with alkali and carbon disulphide, the material is treated with an acid, ammonium sulphate or other bath such as is used in the spinning of viscose silk, or it may be steamed. The process may be applied to the yarns or threads either in the dry finished condition or as they leave the spinning bath or at some later stage in their manufacture.
