Title: Device for mounting yarn tube in winding head - comprising flanged centering ring incorporating expandable split ring
Inventor: MOLLARET MICHEL
IPC: B65H54/553
Filed: 1981-04-15
Abstract: A device for centreing and gripping a yarn-package tube in the yoke of a winding head comprises a flanged centreing tube mounted on one arm of the yoke so that it is freely rotatable, having a series of flats at intervals around its circumference and slots in the flange opposite the flats, and an expandable split ring having a number of dogs which pass through the slots in the flanged ring to engage the inner wall of the yarn tube. The flats of the centreing ring, against which lie the dogs of the split ring, pref. have a slightly concave profile, formed by two ramps inclined at about 1 deg. to the chord joining the ends of the flat, whereby rotation of the split ring relative to the centreing ring forces the dogs outwards to increase the grip on the tube. This is a simple, efficient design which is easy and cheap to manufacture and assemble.

Title: Coating metal uniformly with brazing flux - by applying solid and liquid phases in succession
IPC: B23K3/08
Filed: 1981-11-19
Abstract: A uniform coating of heterogeneous fluid, e.g. brazing flux, is applied to continuously moving metal surfaces, as solid and liquid phases in succession. The solid, in powder form, may be applied by a variety of methods, pref. by a roller, with a network of depressions in the surface, rotating in the outlet from a hopper. The depressions may be hemi-spherical or conical, 3-5 mm. dia., regularly spaced, 2 to 3 cavities per sq. cm., and 1-5 mm. deep. The liquid is a mist, produced by a jet in which the solvent is atomised by gas under pressure. A subsequent hopper/roller may deposit powdered brazing metal. The principal advantage of the process is that by this simple method it is possible to produce a uniform coating, resulting in high quality brazing. The process may also be used for applying glue, enamel, etc.

Title: Graduated sliding support.
IPC: E04F21/00
Filed: 1982-09-10
Abstract: The invention concerns support means for all light materials, which are used by workmen who need an apparatus, in order to support and hold their workpieces, most especially for their rapidity and precision of execution. They are composed of a square metal plate 1 on which is fixed a cylindrical stalk 2 with graduations 17 on which a support block 4, 5, 6 slides. Method already known but distinctly improved, by virtue of the ease of stopping it as soon as the pivoting fork 15 is no longer pressed and by virtue of its precision via the button 7 which actuates the roller 19 pressing against the cylindrical stem 2 and its efficient blocking via a brake 20 actuated by a button 8. This very much improved system makes it possible for operators to support and hold parts with precision. Amongst the most useful applications of the invention, can be cited the holding of rules for tiling walls, supporting and holding parts to be bonded or welded for numerous types of jobs...

Title: Internal combustion engine without a crankshaft.
IPC: F02B3/06
Filed: 1983-12-28
Abstract: The invention relates to a device consisting of a cylindrical shaft 10 into which an elliptical groove 11 is cut as a hollow. A roller 13 securely fastened to a liner 12 converts the reciprocating movement into a rotary movement of the shaft 10 by moving in the groove 11. A double stop 15 prevents the lateral movement of the liner 12. The counter-torque is ensured by the shaft of square section 8 securely fastened to the shaft 10 and sliding between the guides 9 fixed to the casing 3.
