Abstract: The invention relates to a wind power turbine and a gearbox for same. In wind power turbines, the incoming moment is transmitted from a hub to a gearbox via a shaft, and from the gearbox to a generator. According to the invention, the gearbox is at least partially built into the shaft and/or the shaft is at least partially embodied as a rotary gearbox housing. The resulting compact construction not only renders the wind power turbine more compact and therefore significantly more economical and lighter, but in the event of a suitable design and use of a coupling gearbox, the moment generated can be transmitted in a highly secure manner.

Abstract: According to prior art, a transmission of a wind power plant is integrated at least partially into a hollow main shaft. In terms of said type of conception, a shoulder stop is provided to limit deformation of the main shaft. Also, a planetary gear of a wind power plant transmission is placed on a sleeve of a flexpin. In this respect, an intermediate sleeve, in particular designed as a friction bearing is provided. Also known is that the main shaft is placed with a pretensioned rolling bearing in the housing of the wind power plant. In this respect, a hydrostatic friction bearing is used instead. The above-mentioned aspects of the invention enable the service life of the wind power plant to be significantly increased whilst at the same time simplifying maintenance and reducing production and maintenance costs as well as lowering noise emissions.

Abstract: Process for cleaning rolling oils which, when contaminated, contain rolling fines originating from metals being processed into semi-finished products in strip form, in particular light weight metals, e.g. aluminum fines. An addition of 2 to 8 g of dimeric oleic acid is made to each 1000 g of contaminated oil and the mixture passed through a coagulator whereby the rolling fines coagulate and can be readily removed from the contaminated oil. The purified oil can be recirculated as rolling oil.

Abstract: A watch designed to display, by means of indicators (7 to 10) several astronomical magnitudes. The indicators are driven by means of a planetary gear train (19) which is rotatingly supported by means of a ball bearing (20) within a support ring (11) of the watch. The drive force as well as the time reference are provided by a work (C) simultaneously driving the planet-wheel carrier (21, 22) of the planetary gear train and the gear clusters mounted thereon. Each of said clusters has a reduction ratio depending on the indicator (8 to 10) it is intended to drive.

Abstract: The timepiece of the invention includes at least a seconds hand arranged to respond to a chronograph mechanism. It comprises a single motor which receives at least two pulses per second so as to cause the seconds hand to advance by at least two steps per second. The system as disclosed enables an improvement in readability of the precision of time intervals on the one hand and on the other hand assures certain operation of the chronograph while using a stepping motor dimensioned to drive a simple timekeeper.

Abstract: The invention provides a method of converting ethylenically unsaturated units of an olefinic substrate to corresponding cyclopropanyl units, comprising treating the olefinic substrate, in an ether medium, with zinc and diiodomethane and a catalytic amount of a metallo-hydride reducing agent. Preferred substrates are olefinic fatty acids or their functional derivatives, e.g. oleic acid esters.

Abstract: In the quartz watch according to the invention all the time displaying hands (of the hours, the minutes and, possibly, the seconds) are kinematically permanently connected to each other, thus always displaying time in a very precise manner by their respective positions, whichever manipulations are made by the watch carrier.The addition to the conventional parts of the watch of a detector sensitive to the manually controlled displacements of the hands and of a counting device for finishing off these displacements and for memorizing the time impulses during the manual correction, ensures automatically setting the hands in the exact time indicating positions thus permitting the watch carrier who travels from one time zone into another one to make rapidly the necessary time alterations without prejudice of the previous precision of the time indication.

Abstract: A stepping motor particularly intended for electronic watches comprises two poles connected to a core bearing an elongated coil. The poles are joined at nose portions thereof by interposed elements of a material having a magnetic permeability as close as possible to 1. The one-piece stator may be formed by blanking from a composite band, thus considerably simplifying the problem of positioning the poles of the stator relative to the plate of the watch movement and to the rotor. A method of fabricating the one-piece stators efficiently consists in rolling together two strips of ferromagnetic metal and an interposed fillet of non-magnetic metal, these elements being joined at their edges to form a composite band from which the stators are blanked.

Abstract: A pallet lever which is made by first stamping regions, the surfaces of which will be working surfaces and thereafter blanking out the shape of the lever to dimensions in excess of the area of the stamped portion so that the working surfaces of the stamped portion are protected against surface damage to the blanking out operation.

Abstract: A one-piece regulator key for watch movements includes two spaced apart prongs projecting from and integral with a common support, each prong has an inward plane surface facing and substantially parallel to a like inward plane surface on the other prong and is provided at its free end with an inwardly projecting protuberance for decreasing the spacing between the prongs at their free ends.

Abstract: A method of producing an oscillating weight for an automatic wristwatch. The oscillating weightcomprises a heavy-metal segment and a metallic center portion having a flanged rim. For attaching the center portion to the heavy-metal segment, an arcuate groove is formed in the upper surface of the segment, the flanged rim of the center portion is axially inserted in the groove which is slightly wider than the flanged rim, and at one or more locations a portion of the segment is wedged over the rim or a portion of the rim is wedged in the groove by exerting a localized pressure substantially at right angles to the plane of the center portion.

Abstract: A method of punching a small hole in a precision mechanics workpiece, in that the thickness of the workpiece is reduced by the application of pressure in the region where the small hole is to be punched and the material is thereby strengthened, steps being taken to cause the material subjected to pressure to be displaced in the direction of pressure and to yield at right angles hereto. The small hole is punched in the region subjected to pressure at a distance from the edge of that region corresponding at least to the diameter of the small hole, so that the small hole is certain to be punched at a location in that region where the material is strengthened and sound.

Abstract: A watch movement frame comprising a plate having openings therein, a bridge, and at least one spacer member mounted edgewise between the bridge and the plate. The bridge includes separate centering structure and securing structure and the edge portion of the spacer member in contact with the bridge includes corresponding separate centering structure and securing structure. The centering structure of the bridge and of the edge portion cooperate to position the bridge relative to the plate regardless of the inclination of the spacer member and the securing structure of the bridge and of the edge portion cooperate to secure the bridge to the spacer member.

Abstract: The balance cock 35, the train wheel bridge 36 and the barrel bridge 37 are positioned with great precision and univocally on the baseplate 40 by means of an arrangement comprising a pair of feet 38 on every bridge, elongated holes 39 in the baseplate being engaged by feet 38, and securing screws 42, 44, 45 driven into the baseplate 40. Each screw has a conical face on its head and it passes through an opening 41, 46 of the bridge. The conical face of each screw engages the edge of the corresponding bridge opening at one point, thus exerting a thrust on the bridge in the direction of the arrows causing each one of the two feet 38 of a bridge to bear against a plane side wall of the corresponding hole 39 and one foot of each bridge to bear against the rounded end face of its hole.
