Title: Warp thread controlling mechanism for looms
IPC: D03D51/20
Filed: 1931-03-06
Abstract: 366,758. Jacquards. TEFAG TEXTIL FINANZ AKT.-GES., Zurich, Switzerland.-(Assignees of Rossmann, R.; 12, Buchauerstrasse, Munich, Germany.) March 6, 1931, No. 7100. Convention date, March 6, 1930. [Class 142 (i).] Heald needles b, Figs. 1, 4, 8, through which separate warps a, pass are acted upon by one or more thin steel bands e having holes x, or where more than one band is employed, holes and slots y. The needles are guided in a frame c and are acted upon by springs d as shown in Fig. 4, or by weights, so that, on relative vertical movement of the bands and the frame c, certain needles are raised by engagement with a band, while others pass through the holes x and slots y to form the lower shed. By the movement of a band in the direction of its length by a distance equal to the diameter of its holes x, those needles which would otherwise have passed through the holes in that band are held in the raised position, while such movement does not affect the needles passing through the slots y in that band. The bands extend across the width of the warp in groups of superposed bands, such groups being arranged one behind the other. Where each warp is to be controlled individually, there is provided a band for each warp having one hole x only, the other apertures beneath the other needles of its group being in the form of slots y. By providing slots and holes in the bands, each band of a group can be arranged to control, for example, every tenth heald needle of that group. To operate the bands in the direction of their length and thus to control the pattern woven, each band is normally drawn to the right by a spring n, and has an extension passing through a frame f<1>, Fig. 12, and having slots u and holes v through which pass needles g<1> . . g<6> controlled by a jacquard card k on a cylinder i. In operation, blades l on a carrier m engaging within elongated apertures z in the bands move them all to the left against the action of their springs n. Upon movement of the cylinder i, the holes k<1> in the card k allow certain needles g<1>, g<3>, g<4> to pass into holes il in the cylinder, while those that are raised by the card pass through the slots u and holes v of the bands. When the member m moves again to the right, the raised needles g2, g<5>, g<6>, by engaging in the holes v lock the corresponding bands e<2>, e<5>, e<6> in their displaced positions, the slots u allowing the remaining bands el, e3, e4 to move to the right under the influence of their springs. The bands may be arranged above the warps or below them, as shown, while the parts may work in an oil bath as indicated in dotted lines in Fig. 1.

Title: Electric tachometer
IPC: G01P3/46
Filed: 1932-03-18
Abstract: 400,594. Electric speedometers. LANGE, B., 28, Werderstrasse, Dahlem, SCHWARZ, A., 6, Viktoria-Luise-Platz, both in Berlin, and GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London. March 18, 1932, No. 8172. [Class 106 (iii).] An electrical tachometer with alternating current dynamo and dry rectifier, e.g. selenium or copper oxide plate rectifier, is characterized in that the dry rectifier is contained within the dynamo casing and is covered with an insulating composition for protection from the atmosphere and damp and for retaining the rectifier in position. The dynamo casing 7 has within it the rotated multipolar permanent magnet 1 and the cylindrical metal pole casing 3 divided by a partition having secured to one side metal studs corresponding by number to the number of poles of the magnet and forming cores for the stationary current coils 2, and having in the cavity on the other side the dry rectifier 4 connected by the lead 5 to the indicating instrument. Both sides of the pole casing are filled with an insulating composition which may be poured in liquid form over the casing and may then set solid. This insulating composition protects the various components from the atmosphere and damp and serves to retain them in position under shock, e.g. when mounted on a vehicle. The end of the casing 3 is protected by the cover plate 8 and the magnet 1 is protected from atmospheric influences or from damp by filling the dynamo casing 7 with a fluid insulating medium such as oil so that the dynamo becomes completely gas-tight and water-tight and will operate under water. The casing 3 has a screw-threaded engagement at 6 with the dynamo casing 7 so that the air gap between the magnet 1 and the current coils 2 can be varied, the casing 3, current coils 2 and rectifier 4 forming a structural unit through the medium of the insulating composition.
