Abstract: - i -Abstract of the Disclosure A slat-type article counting machine includes slats provided with cavities which carry the articles, an exact count of which are designed to be discharged into bottles or containers.  Each cavity defines a hole which penetrates the entire slat depth.  Two pairs of scanners are mounted to the machine, one for detecting missing articles from cavities and the other for detecting articles wedged or blocked there-in.  A pair of scanners comprises sensors which include an array board having multiple light-emitting diodes which pro-ject light beams through the holes provided in the cavities to thereby strike photoelectric cells mounted to another array board, which photoelectric cells generate signals which co-operate with sensing and logic circuits for effecting visual and audible means for indicating miscounts due to empty or blocked cavities.  A wide range of auxiliary operations and functions may additionally be initiated by the signals.

Abstract: ABSTRACT OF THE DISCLOSURE      This invention is directed to the production of sealing glasses capable of forming strong, non-porous seals with glasses containing at least 10% by weight of an alkali metal oxide such as are used in the fabrication of the glass membranes utilized in sodium-sulfur and potassium-sulfur batteries.  The inventive seals require an interdiffusion of ions to occur between the sealing glass and the glass being sealed.  Glasses presently employed as membrane glasses for such batteries have base compositions within the Na2O-B2O3 and X2O-B2O3 systems.  The inventive sealing glasses consist essentially, expressed in mole percent on the oxide basis, of about 3-30% R2O and 60-95% B2O3, wherein R2O consists of K2O, Rb2O, Cs2O, and mixtures thereof and, optionally, Al2O3 is substituted for up to one-half the E2O3 content on a molar basis.  The seals contemplate the exchange of large alkali metal ions from the sealing glass for the smaller alkali metal ions of the membrane glass.

Abstract: ABSTRACT OF THE DISCLOSURE            The invention relates to a method and apparatus for forming a directioned and controlled suspension spray of a pulverous material and reaction gas in such a manner that the reaction gas directed along one, often horizontally approaching channel is divided into three or more partial channels by means of mainly radial partition walls.  When necessary, guide blades or a venturi-like mixing and guide member is used.  The reaction gas is deflected so as to have the desired direction, often vertically downwards so as to be parallel to the central axis of the reaction chamber, such as a flash-smelting furnace.  The thus formed partial flows of reaction gas are often caused, furthermore, to discharge, divided further into two or more parts, as an annular flow encircling on each side the member for feeding pulverous material, situated in the middle of the flow, into the reaction chamber.  The pulverous material, dispersed well only in the reaction chamber, is mixed effectively with this as a whole non-rotating but turbulent reaction-gas flow, the pulverous material being directioned mainly radially in order to achieve a velocity difference between the reaction gas and the pulverous material.
