Abstract: A method for fabricating pallets for an escapement system concerns the field of escapement systems for timepieces. The method includes forming integrally, using a first material, a lever of pallets. A first end of the lever includes a dart. A second end of the lever includes two arms each for receiving a pallet stone. The method includes over-moulding a second material different from the first material on the first end of the lever in order to form a pallets fork. The method includes mounting the pallet stones and a staff to enable the pallets to be rotatably mounted.

Abstract: Method of securing a watch bezel 1 including a case 3 and a crystal 2, characterized in that it includes a step of snap fitting the bezel 1 onto the crystal 2, during which snap fit means 6 are guided by guide means 5 arranged on case 3.

Abstract: The tool, which can be adapted to a bracket for fitting hands on a dial by driving them in, including a lower rod (11) which slides in a tubular part (13a) of an intermediate cylindrical element (13) compressing a spring (33) abutting against first tension adjustment means (43) and with an overlap that can be checked by a movement indicator (34) for a first force F1, said intermediate cylindrical element (13) itself sliding in the upper tube (15) compressing a second spring (35) abutting against second tension adjustment means (45) and with an overlap that can be checked by a movement indicator (36) for a second force F2.

Abstract: An electrode assembly constructed of continuous anode and cathode electrode that are overlaid in overlapping fashion and folded several times rather than wound into a cylinder in the conventional "jelly roll" electrode assembly. The electrode assembly has a first side that is curved substantially along a single arc and a second side opposite the first side that is curved substantially along a plurality of arcs. The electrode assembly is designed for casings for electrochemical cells or batteries having profiles that are not well suited for the jelly roll configuration.

Abstract: An electroforming process and apparatus for forming an electroform with a roughened surface. The present invention roughens the surface of the mandrel using a sandblasting device in the center region of the mandrel allowing the two end regions to remain smooth. The intersection of the roughened center region and each of the two end regions form a step. This step on either side of the roughened center region facilitates sealing while the roughened center region enables toner distribution. The electroform created using the step roughened mandrel surface is separated from the mandrel without destroying the mandrel. The step roughened mandrel can then be reused to create another electroform with a roughened surface.

Abstract: The electrode structure includes a cathode, anode and polymeric separator, wound into an oval configuration having a length and width equal to interior dimensions of the rectangular housing. The oval shape is achieved by winding a long, flat electrode structure around a mandrel. The length of the electrode structure is chosen based upon the size of the mandrel, the interior dimensions of the housing, and the width of the electrode structure, such that, after winding, the resulting oval structure snugly fits within the rectangular housing leaving no remaining spaces, other than in corners of the housing. A leaf spring is provided between a free end of the electrode structure and an interior wall of the housing for ensuring that the electrode structure remains tightly wound. Appropriate electrical contacts are provided to the anode and cathode of the electrode structure.

Abstract: A panel of thin bendable material is provided and includes one marginal portion thereof for disposition adjacent the worn side of a journal bore in a clock frame plate with the panel disposed parallelly in juxtaposition with one side of the plate. The aforementioned marginal portion of the panel includes a narrow elongated lengthwise outwardly projecting tongue disposed generally normal to the panel for reception in the worn side of the bore. The tongue is concavo-convex in cross section with the convex side opposing and seated against the worn side of the bore and the concave side of the tongue opposing the side of the bore remote from the worn side thereof. The tongue, therefore, defines an insert for renewing the worn side of the bore and against which the corresponding clock component shaft portion may be journaled.

Abstract: A tool for the precision press-fitting of watch bearings, watch hands, collets and other precision press-fit parts. The tool is used in conjunction and as an attachment with traditional watchmakers' staking sets. The tool consists of a cylindrical metal rod, hollow and slit at its lower end to accommodate friction-fit pushers of various end-dimensions. The cylindrical rod is threaded in metrical or inch pitch for one-third of its lower length to accommodate a knurled disk upon which are marked the divisions of a linear unit, similar to the thimble of a micrometer. At its upper end, the rod is milled to a short rectangular section. Upon this rectangular end is positioned a flat metal clamp with close fitting but not tight, rectangular hole. The clamp is split at its outer end, forming two legs which are form-bent downward to straddle the gooseneck of a staking set. The threaded, micrometer nut is threaded up against the bottom of the staking set's hollow punch-guide.
