Title: Improvements in or relating to single phase commutator dynamo-electric machines
IPC: H02K27/02
Filed: 1930-04-22
Abstract: 353,469. Alternating current commutator machines. OSTERREICHISCHE SIEMENS - SCHUCKERT - WERKE, 150, Engerthstrasse, GRABNER, A., 9, Pressgasse, and STIX, R., 9, Hintere Zollamtsstrasse, all in Vienna. April 22, 1930, No. 12454. [Class 35.] Windings; commutating poles.-A single phase commutator, particularly a railway motor, for operation on frequencies greater than 25, has a lap wound armature with an increased number of commutator segments and a phase displaced commutating field for the purpose of making the transformer voltage between adjacent commutator segments equal to or smaller than the reactance voltage at the working speed chosen. The additional commutator segments are connected by intermediate connections to the coil ends or they may be completely insulated or connected to the main segments through resistance, inductance or capacity. Fig. 1 shows an armature winding connected to main commutator segments 1, 3, 5 &c. and having intermediate segments 2, 4, 6 which are connected to the coil ends I, II, III, &c. by intermediate connections a which run under the core. Laminated commutating poles (not shown) are located between the main poles N, S. Equalizing connections A may be employed at both ends of the armature in which case the number of connectors a can be reduced to the number of auxiliary segments for one pair of poles. The connectors a may be carried in the winding slots, preferably at the top, if the main poles are divided as in Fig. 3, so that the connectors a are located under field free zones at the moment of commutating. Alternatively, the poles may be divided transversely so that the intermediate connectors run partly in the circumferential direction as shown in Fig. 5. Each connector accordingly comprises two parts separated by a pole pitch in which voltages are induced in opposite directions, but if the two parts are situated so as to be in field-free zones at the moment of commutation, they need not be equal in length. The number of connectors mav be increased with a consequent further subdivision of the polepieces. The two parts of a pole, Fig. 5, may be relatively staggered in the circumferential direction and the armature conductors and intermediate connections bent oppositely. Specification 4493/06, [Class 35, Dynamo-electric generators &c.], is referred to.

Title: Method of and apparatus for producing corrugated patterns in textile fabrics
IPC: D06C29/00
Filed: 1937-05-01
Abstract: 494,949. Corrugating fabrics. WELTI, K. May 1, 1937, No. 12461. Convention date, Sept. 23, 1936. [Class 141] [Also in Group XVI] Crimped or corrugated effects are produced on fabrics by mechanically bunching the fabric during its passage between a heated surface and tensioned wires or the like holding it against the surface, a flexible backing strip moving with the fabric being interposed between the fabric and the surface or the wires. The web of fabric 52 to be treated passes in a preferably moistened condition from a roll 51, around a heated driven cylinder 4 together with a backing web 54 of muslin and is delivered to a tray 61. Rollers 11, 16 carried by weighted levers 10, 15, respectively, form guides for wires 47 attached at one end to a rod 46 and at the other end carrying weights 49, the wires serving to press the fabric on to the drum. The roller 11 is driven from the drum 4 by toothed gears 12, 13, so that its speed is somewhat less than that of the drum and the roller 16 is driven frictionally by the drum but is provided with a hand-wheel 18 or braking- means which may be automatic, whereby its speed is retarded so that the fabric is bunched up or corrugated between the rollers and at the same time is pressed by the roller 16 and the wires 47. An endless backing-web 57 of muslin passes between the fabric 52 and the wires 47 and subsequently passes over a heated drying roller 50 and also over a guide sheet 58. One of the webs 54, 57 may have patterns formed thereon by weaving so as to produce a patterned effect on the fabric 52. The weights 29, 30 controlling the levers 10, 15 are carried by levers 25, 26 respectively, connected by adjustable links to the levers 10, 15. In order to insert the fabrics 52, 54 between the drum 4 and the wires 47, the rollers 11, 16 are lifted off the surface of the drum by operating a hand-wheel which turns a shaft 36 carrying levers 38 with rods 40 attached thereto, pins 41, 42 on the rods being adapted to engage the levers 25, 26 in order to effect the raising of the rollers 11, 16. The wire-carrying rod 46 is fixed to a threaded bar 45 adjustable by means of a hand-wheel 44 in order to take up slackness in the wires. Grooves may be provided in the rollers 11, 16 to receive the wires 4. Further, a number of pairs of rollers 11, 16 may be employed.
