Title: Guarantee seal for bottle stopper - has skirt with tear off tongue formed by extension beyond joined ends
IPC: B65D55/08
Filed: 1981-12-15
Abstract: The guarantee-sealing skirt for a bottle stopper has a tear-off tongue and comprises a strip of heat-shrinking material, one of whose ends (4b) is folded onto the other (4a). The tongue (6) extends to the side, and is formed by an extension of the strip beyond the area (5) where the ends are joined together. It can be adjacent to a weakened zone formed by a line of perforations parallel to the lengthwise axis of the skirt, in the part of the latter covered by the tongue and near where the strip ends are joined together. The tongue may be narrower than the height of the skirt, working with two weakened zones formed by parallel lines of perforations extending from the tongue edges.

Title: Methyl tert.-butyl ether prodn. from mixed butene feed - by reacting isobutene with methanol and isomerising n-butene(s)
Inventor: CONVERS ALAIN
IPC: C07C41/06
Filed: 1982-01-26
Abstract: Upgrading of C4 olefinic fractions from which butadiene has been removed is effected by (a) reacting with MeOH to convert isobutene to methyl t.-butyl ether (MTBE); (b) fractionating the prod. to obtain a MeOH fraction, a MTBE fraction and a C4 hydrocarbon fraction; (c) recycling the MeOH to (a); (d) subjecting the hydrocarbon fraction to selective hydrogenation to remove residual butadiene; (e) subjecting the hydrocarbon fraction to extractive distn. with a solvent to remove paraffins; (f) isomerising the prod. to convert n-butenes to isobutene, giving a prod. with a compsn. close to thermal equilibrium; and (g) sepg. C3-hydrocarbons from the prod. and recycling it to (a). MTBE is useful as a high-octane gasoline additive; it may also be cracked to produce high-purity isobutene. The process allows practically all of the C4 olefins in the feed to be converted to MTBE.

Title: Submerged power generator using water waves - has chambers with flexible domes and contg. liq. expelled by pressure of water acting down, to drive turbines
IPC: F03B13/14
Filed: 1982-02-19
Abstract: The submerged generating unit includes a rigid enclosure mounted on pylons which support it at a fixed depth below the surface of the water. The enclosure is divided into a series of chambers each of which has a flexible dome covering it. The dome on each chamber is such that it may be deformed by the pressure of water under the crest of a wave. When a dome is deformed, water is expelled from the corresponding chamber via a system of non-return valves so that it passes two turbine blades situated one at either end of the unit. More than one such unit may be linked together, and they may be staggered in the direction of wave travel.

A third key (22) validates the set values and initiates entry into the chosen program, while a fourth key (23) cancels the selections. The first two keys (19,21) can be used to set the times in the program after the timer key (16) has been pressed.

Title: Technique for making pictures with surface relief - uses varying thickness of ribbon or glue to form trace and colouring may then be sprayed on
IPC: B44D2/00
Filed: 1982-03-08
Abstract: The picture making mathod produces designs with surface relief and is carried out independently of any colouring process. It uses products which re-act chemically with one another in situ to obtain different colours and/or novel effects. The trace or line may be formed by a ribbon of glue of varying thickness, aerosol lacquers then being used to provide colouring with a ceramic effect. Interactive inks and paints may also be used to form a modelled metallic base, an alternative basic design being obtained by cutting metal sheet and treating it in preparation for painting. A design may use cut out zones, with colours applied by traditional means.

Inventor: CONRAD PETER
IPC: D01H9/00
Filed: 1983-03-03
Abstract: The invention relates to a tube-gripping device with automatic tolerance compensation, having an annular clamping element provided for each spinning station and designed as gripper tongs. The object on which it is based is to provide a gripping device, by means of which large and heavy bobbins with tubes of wide tolerance can be clamped securely by a gripper and a common drive can be used for a plurality of clamping points. This object is achieved in that wound or non-wound tubes (6) are clamped by means of these gripper tongs (5) and the gripper tongs (5) are actuated by a closing mechanism (4) which is driven by a four-bar linkage having an elastic link (3) and a common driving slide (2) for at least two work stations. The invention achieves the technical effect that a tube-gripping device works without elastically lined gripper elements, the gripper elements themselves do not consist of elastic material and the gripper elements require no individual drive.

Patent FR-2552780-A1 (FR)
Inventor: DUBOST BRUNO
IPC: C21D1/667
Filed: 1983-09-29
Abstract: The invention concerns a method for minimizing deformation during rapid cooling of flat metallurigcal products such as sheets, strips, flattened portions, wide sections and the like. The method comprises rapidly cooling the product by means of a fluid (or mixtures of fluids) at temperature TF, comprising at least one vaporizable liquid, with modulation in a direction perpendicular to the direction of advance of the product, so as to impart different cooling speeds to the edges and the axis (case I) or to one edge and the other (case II). The technique may be completed by careful masking of the cooling in the zone for the rapid cooling action, or by controlled precooling prior to said rapid cooling. The method makes it possible to obtain the rapid cooling which is necessary e.g. in quenching operations, while at the same time minimizing the deformations or the internal stress level of flat products.

Abstract: Method of welding two hollow ceramic half-components containing an organic binder whereby each half-component is first loaded into a die, the jointing planes of the two half-components are then brought into contact by bringing together the two dies, working pressure is thereafter applied to one of the half-components in a direction perpendicular to the jointing planes and vibration is simultaneously applied to the other half-component in a direction parallel to the jointing planes to effect the welding of the two half-components by interpenetration. The two dies are then separated and the joined monobloc component is removed and sintered without altering the component's monolithic quality.
