Abstract: A grey glass composition is suitable for architectural and/or vehicle window applications. The grey glass may achieve a combination of good visible transmission, a low SHGC, and desirable coloration. In certain example embodiments, the grey glass includes iron, erbium (Er), neodymium (Nd) and/or praseodymium (Pr) in the colorant portion of the glass.

Abstract: A coated article includes a glass substrate that supports a coating such as a low-E (low emissivity) coating. In certain example embodiments, the glass substrate is formed of a soda-lime-silica based glass composition manufactured using a float process. In certain example embodiments, lithium oxide (e.g., LiO2) and/or potassium oxide (K2O) is used in the soda-lime-silica based glass substrate in order to reduce sodium migration and/or improve surface stability. Such coated articles are useful, for example and without limitation, in architectural, vehicular and/or residential glass window applications.

Abstract: A soda-lime-silica based glass composition for manufacturing on a float line that has a faster refining rate due to the introduction of alkali earth oxides such as BaO, ZnO and/or SrO in the amount of from about 1-4% in total. These oxides replace part or all of the MgO in the base glass composition thereby decreasing the overall MgO content in the glass composition to about 2% or less. The glass can realize a lower viscosity at high temperatures so that refining of the melt may occur faster.

Abstract: A high transmission and low iron glass is provided for use in a solar cell. The glass substrate may be patterned on at least one surface thereof. Antimony (Sb) is used in the glass to improve stability of the solar performance of the glass upon exposure to ultraviolet (UV) radiation and/or sunlight. The combination of low iron content, antimony, and/or the patterning of the glass substrate results in a substrate with high visible transmission and excellent light refracting characteristics.

Abstract: A grey glass composition employing in its colorant portion, in certain example embodiments, iron, cobalt, nickel, and at least one of erbium and titanium. The use of erbium and/or titanium has been found to improve coloration of the grey glass, and improve tunability of the same. In certain example embodiments, the ratio of cobalt oxide to nickel oxide is from 0.22 to 0.30 in order to achieve desired coloration in certain example embodiments.

Abstract: An apparatus and method for bending and/or tempering glass substrate(s) are provided. The amount of near-IR radiation which reaches the glass to be bent and/or tempered is limited (e.g., via filtering or any other suitable technique). Thus, the IR radiation (used for heating the glass) which reaches the glass to be bent and/or tempered includes mostly mid-IR and/or far-IR radiation, and not much near-IR. In such a manner, coating(s) provided on the glass can be protected and kept at lower temperatures so as to be less likely to be damaged during the bending and/or tempering process. Heating efficiency can be improved. A ceramic (e.g., aluminosilicate) filter or baffle may be used in certain embodiments in order to reduce the amount of mid-IR and/or far-IR radiation reaching the glass to be tempered and/or bent.

Abstract: Soda-lime-silica based glass is provided so as to have an improved (i.e., reduced USPX value). In certain example embodiments, the USPX value may be reduced in a desirable manner by reducing alumina and sodium content, while increasing content of material(s) such as MgO and/or CaO. The lower the USPX value, the better the stain resistance of the glass.

Abstract: A method and apparatus to connect a group of users via a communications network for a conference call. An initializing signal from an initializing user is detected and the initializing user is allowed to select a predefined user group. The user group comprises a list of users and their associated phone numbers that is created by a user using an user interface of a web portal and stored in a web portal database. After the selected user group is retrieved the availability of each user listed in the user group, for a conference call, is determined by connecting to each user via a communications network, announcing the initializing user to the connected user, and requesting a response from the connected user to determine if the connected user is available for the conference call. The available and connected users are interconnected with one another to allow the users to communicate in a conference call.
