Title: Improvements in regulating transformers
IPC: C10M175/00
Filed: 1929-06-27
Abstract: 335,283. Thoma, H. June 27, 1929. Regulating transformers. - The brush of a regulating transformer is displaced longitudinally by a spindle positively coupled by gearing to the rotary coil of the transformer, and current is supplied to the coil by leads passing through cavities in the shaft and yoke. The core K, Fig. 1, carries the insulated flat copper winding F and is mounted to rotate between the yokes I, X. The ends A', A<2> of the winding are led through holes in the shaft and grooves N in the core. The brush contact B is mounted on a screw spindle Y which rotates when the core rotates, so that the brush always makes proper contact with the winding. Several brushes B may be mounted adjacent each other, and the connecting leads from the brushes are taken outside by insulated contact bars, so that the effect of the pulsating flux balances the voltage of one turn of the regulating winding. In the modification shown in Fig. 2, the slit core L is fixed to the yoke I so as not to rotate, while the short rotatable part D attached to the winding F is separated by air gaps from the part L and the yoke X. In this form a separate exciter winding R is arranged between the core L and the winding F. The-rotatable part D of the core may be omitted; the current lead M then has the form of a twisted bar, similar to the twisted bars used in generators, and passes through a simple air-gap. In another modification a pole-piece is attached to the core L. In another modification the core L, Fig. 4, carries the primary winding G, while the secondary F is wound on the insulating cylinder S, which extends through the yoke X and supports the slip rings U. The stampings V of the yoke X are slotted and separated by presspahn, the outer stampings being separated by thicker pieces of presspahn than the inner layers. Multiple leads for conducting the current may be used and are connected by suitable resistances or choking coils.

Abstract: 799,102. Planographic printing plate developers. MINNESOTA MINING & MANUFACTURING CO. June 26,1956. No. 19818/56. Class 98(2) The developer, whose function is to colour ink-receptive areas of a printing plate of the diazo-resin or dichromatealbumen type to render them visible for inspection, and to ensure ink and water receptivity in the respective areas, comprises a coloured two-phase liquid composition having an aqueous phase comprising water and a soluble thickener, and a non- aqueous liquid resinous phase comprising an unmodified hydroxyl-containing resinous glycidyl polyether of a dihydric phenol and a water-immersible solvent. In Example 1 the aqueous phase is a gum arabic solution with wetting agent if desired, and this is combined in a mixer with the non- aqueous phase of an epichlorohydrin-bisphenol (soft epoxy) resin with touidine toner as pigment in ethylene dichloride/ cyclohexanone solvent to produce a waterin-oil type emulsion. Six further examples describe very similar compositions, some of which are of oil-in-water type, and the manner of production of the resins themselves is indicated. In use the compositions are wiped over an exposed diazoresin plate after this has been subjected to a photographic development with aqueous gum arabic, or over a dichromate-albumen plate directly after exposure for subsequent removal of unexposed areas, when the plates are ready for printing using any ordinary ink and fountain water and have superior wear resistance or the plates may be coated with gum arabic for storage.

Title: Improvements in electric discharge tubes
IPC: A61N5/08
Filed: 1930-07-01
Abstract: In therapeutic apparatus producing ultraviolet and infra-red rays simultaneously, an electric discharge tube generating the former rays is connected in series with a glowing wire or other device generating the latter rays so that the efficiency, as compared with prior devices in which the wire and tube are in parallel, is improved by using the wire as part or the whole of the ballast resistance of the tube.  The tube may have activated electrodes and may operate at 5 amps. and less than 100 volts. The tube and wire may be in a common reflector focusing the rays from both on the same spot or the wire may be in a separate receptacle or reflector.  If the wire generates too much infra-red radiation when used as the whole ballast, this radiation may be weakened by a diaphragm or the wire may be placed at a greater distance from the body than the discharge tube or an ordinary ballast resistance may be used in series with the wire and tube. The infra-red radiator may be a spiral or double spiral wire or band glowing in air or gas such as hydrogen or may be an ordinary lamp emitting visible rays as well.
