Abstract: A forming device applied to a cigarette manufacturing machine causes a garniture tape 10 to travel through a wrapping section 8, and meanwhile wraps a shredded tobacco layer T in wrapping paper P to form continuously a cigarette rod R. The tape 10 is guided to travel by a forming guide 18 in the wrapping section 8, and is simultaneously bent to have a cross section of an arc that is downward convex. On the other hand, the travel of the tape 10 is guided by a pair of guide rollers 24 in upstream and downstream sides of the wrapping section 8, and the tape 10 is bent to have a cross section of an arc that is upward convex by guide surfaces of the rollers 24. Thus, difference of travel length, that is generated between both side edges and the central part of the tape 10 in the wrapping section 8, is offset by the guide rollers 24.
Abstract: Devices and techniques for placing and bonding identical elements to holes in a substrate where spacer balls and a reference surface are used to achieve the desired accuracy.

Abstract: A method for increasing the photosensitivity of a selected portion of an optical fiber and for producing a grating in the selected portion of an optical fiber. The method includes the step of placing the selected portion of the optical fiber in a hydrogen containing atmosphere. The volume of the hydrogen-containing atmosphere immediately surrounding only the selected portion of the optical fiber is heated to a temperature of at least 250° C. Only the selected portion of the optical fiber is exposed to the heated volume of the hydrogen-containing atmosphere at a temperature of at least 250° C. for a predetermined time.

Abstract: Disclosed are silicoaluminophosphates (SAPOs) having unique silicon distributions, a method for their preparation and their use as catalysts for the catalytic cracking of hydrocarbon feedstocks. More particularly, the new SAPOs have a high silica: alumina ratio, and are prepared from microemulsions containing surfactants.
