Definitions

  • the present invention relates to glasses, in particular Watch glasses, with inserted stones, preferably in shape of gemstones, especially gemstones, Semiprecious stones and / or synthetic stones and Method of making such glasses.
  • the object of the present invention is to create Glasses, especially watch glasses, which are shapely integrated dial or an elegant have an integrated time scale and e.g. for installation in serve a wristwatch or pocket watch.
  • this object is achieved by a glass, especially in the form of a watch glass for installation in a Wristwatch or pocket watch with an integrated dial or an integrated timescale, whereby the Dial or the time scale one, four or twelve or more stones, preferably in the form of diamonds, in particular Brilliant and / or gemstones and / or synthetic Stones and preferably in different Sizes, types of stones and / or colors.
  • the stones can be placed directly in the glass, preferably with the interposition of a solder glass section be framed.
  • the stones according to the invention in the glass be framed by means of gold frames, preferably on recesses on their outer surface adjacent to the glass and / or constrictions and / or protrusions or widenings have to keep the frames in the glass improve.
  • a funnel which is designed and in which a stone, especially a diamond, is set is that he is essentially only in the area of his Rundiste is in contact with the funnel and between an air gap between the bottom of the diamond and the funnel is present, with the funnel at its Anchoring one that extends into the glass plate Can have a foot part with a constricted upper Section and a widened lower section.
  • the stones can alternatively be used of an adhesive in the glass, instead of Glass or in combination with glass, plexiglass, plastic sheets and / or crystal plates can be used.
  • one can be used to manufacture the glasses Use a vacuum oven in which a glass with the stone or Diamonds and which is flooded with nitrogen, using the vacuum oven as a work place to surround the stone or diamond in the glass and the Vacuum oven first evacuated before heating and then is flooded with nitrogen and the vacuum oven is preferred evacuated again after the first evacuation and flooding and flooded again with nitrogen and preferably the entire vacuum furnace including the vacuum pump, also with nitrogen during the heating process is flooded so that the vacuum pump has no fresh air sucked in, but nitrogen and a double nitrogen cycle is achieved with a total removal of the Atmospheric oxygen, so that the stone or diamond during the heating process remains undamaged.
  • a diamond According to the invention can be placed in a glass plate at the points to which a diamond should be set one section at a time be inserted from solder glass, which with a, preferably not provided through step hole , into each of which a diamond is inserted, whereby then preferably in a double vacuum oven Nitrogen cycle to a temperature between about 400 and heated to 750 degrees Celsius.
  • Diamond has a coefficient of expansion of approx. 8 x 10-7 at normal temperature. The hotter the diamond gets its coefficient of expansion becomes higher. At 1000 degrees Celsius is the coefficient of expansion approx. 40 x 10-7.
  • the glass To not only glue the stone into the glass, but around To be able to frame it correctly, the glass must be placed on a Temperature to be heated at which it is at least soft is. This temperature is around 750 degrees Celsius.
  • a third problem is that the effect of the diamond, or gemstone is based on the fact that the light is reflected (preferably a total reflection) on the underside of the stone is directed back upwards and thus catches the eye of the beholder again.
  • the sparkle of the stone is based on these reflections of light inside the diamond (gemstone).
  • the reflection (in particular the total reflection) takes place due to the different optical densities of Gem and air.
  • a vacuum oven is used in which the glass is connected to the diamond and which one flooded with nitrogen. It is important that none Residual air remains in the oven and deals with the nitrogen mixed, because even a very small amount of Atmospheric oxygen changes the surface of the Diamonds during the melting process of the glass.
  • a vacuum oven is therefore used as a work station used to frame the stone in the glass. In front When the furnace is heated, the furnace is first evacuated and then floods it with nitrogen.
  • the nitrogen-air mixture is evacuated again and the furnace is flooded again with nitrogen. Theoretically, you would then have a residual air share of 1 percent of a percent, ie a ten-thousandth of a percent. But this is only theoretically the case, because if a vacuum pump is able to maintain a vacuum of 1 percent, it means that it sucks in as much air as it does through leaks (often through the pump itself) back into the vacuum entry. So it keeps the balance at about 1 percent pressure (or air). However, the re-entering air changes the air-nitrogen mixture to the disadvantage of nitrogen. If the furnace chamber is evacuated several times and flooded with nitrogen again in order to obtain a residual fraction of air of a fraction of 1 percent, then this low oxygen percentage does not remain the same while the vacuum pump is running, but it slowly shifts back to the one percent ,
  • the entire vacuum furnace is surrounded together with the vacuum pump, during the heating process also with nitrogen or you flood all potential leaks in the vacuum body also with Nitrogen.
  • the vacuum pump does not suck Fresh air, but nitrogen.
  • the heating is therefore preferably carried out in a vacuum furnace with a double nitrogen cycle.
  • the top part has the task of letting the light into the stone.
  • the light through the board becomes relative recessed and through the top facets, which are around the board so bent that it is in ideal angle occurs.
  • the top part also has the task of reflecting Then let the light out of the stone. there the light is through the panel or through the top facets so bent that it is ultimately where possible falls back to where it originally came from. This makes the stone the largest for the viewer Effect.
  • the lower part of the stone has the task of light which has fallen through the top part to reflect that it goes through again without any loss of light the top emerges, and moreover at the correct viewing angle exit.
  • the girdle (the connection between the upper part and lower part) usually has only technical meaning and no visual meaning.
  • the girdle is a band around the stone (like a kind of belt), which is perpendicular to the board. If the top and bottom were to meet without a girdle, this would result in a razor-sharp edge with an acute angle. This would lead to breakouts and the stone would always be damaged. That is why a girdle of approx. 1 to 3 percent of the total height of the stone is created with transition surfaces perpendicular to the table around the stone. Light that hits the girdle from the inside is usually lost in the light play of the diamond. It emerges to the outside or is reflected in such a way that it does not exit through the upper part at the correct angle. If the diamond meets the glass on the girdle, this has no significance for the optical effect of the diamond.
  • a diamond is preferably inserted into the glass in this way edged that if possible only with the girdle or the immediately adjacent areas of the upper part and Bottom part in the glass sits to the optical qualities of the To get stones. Care should also be taken that the stone is set so that in the "Air area” around the bottom of the stone none Liquids, or skin cream or other Contaminants penetrate. Otherwise he will lose Stein also has its full visual impact. The So stone should be set so that inaccessible Placement of the "air area" surrounding the lower part are watertight.
  • Gemstones there are several diamond (or other) options Gemstones) in glass although both materials have different expansion coefficients.
  • a Possibility is to interpose a material which either elastic or flexible in its extension is so that it bridges the different coefficients. Such a material is e.g. Fine gold that itself different expansion coefficients if it sits between glass and diamond.
  • Gold has a coefficient of expansion of 140 x 10-7, which is larger than that of glass: but because of its softness it doesn't matter. You can melt gold with glass without the glass cracking.
  • Pure gold is the best material for yellow gold. It most easily connects to the glass. With white gold is an alloy of 85 parts by weight of fine gold and 15 parts by weight of palladium are most suitable.
  • solder glass This is a jar which is the coefficient of expansion between normal glass and bridge all possible materials (e.g. ceramics) can.
  • Another method to prevent stress cracks in the glass is to simply remove the diamond from the glass separate. You can grow together with a release agent of diamond and glass during the melting process. However, the release agent mostly changes the optical qualities of the diamond, or is itself visible if it is not transparent. You can but possibly remove it after the melting process. As a result, the diamond sits loosely the version. Depending on the design of the object, this may not be the case be annoying. You can also use the diamond after Fix the melting process of the glass again, e.g. with a fine silicone adhesive that runs along the girdle and connects the stone to the glass at this point. This is also a great way to prevent that Liquid or creams in the "air area" of the diamond setting penetration.
