Abstract: The impact beam of a mechanical printer is constructed for noise dampening and yet exhibits a high resistance to wear. The beam unit comprises a block of dampening material which is held along a carrier support wall. A strip of metal is arranged along an exterior, generally flat surface of the block so as to be completely separated from adjacent surfaces of the support wall by a region of block material. The metal strip is arranged to receive the impact of type bars and other noise-inducing mechanical force elements of the printer. The noise emanating from such impacts are dampened as they travel through the block material. There is no direct connection between the metal strip and the housing of the mechanical printer in order to prevent direct transmission of noise vibrations from the strip to the housing.

Abstract: Optical fiber fabrication processes which involve fabrication of glass tubes which form an integral part of optical fiber preforms from which optical fibers are drawn. The glass tubes are fabricated from tubular structures (e.g., 14) comprising amorphous powdery particles. The tubular structures are heated (e.g. by 15) so as to fuse the particles thereby yielding a transparent tubular glass structure of optical fiber quality. During the fusing step, the structure is substantially constrained against shrinkage in both the radial and longitudinal direction thereby yielding a glass tube with improved dimensional characteristics. The so produced glass tube may then be either drawn into an optical fiber or may be collapsed into a rod which then may be drawn immediately or eventually, into the optical fiber.

Abstract: Unsaturated hydrocarbons and mixtures in which the latter are present are treated with anion exchangers prior to hydrogenation and are then hydrogenated catalytically in a known manner. The treatment with anion exchangers is carried out at 0 DEG -120 DEG  C. and at a space velocity of 0.1 to 10 l of hydrocarbons to be hydrogenated per l of exchanger, per hour. The process avoids other, energy-intensive pretreatments, for example distillation of the hydrocarbons to be hydrogenated, or washing, and can be carried out in simple equipment. A considerable prolongation of the catalyst operating time is achieved in the subsequent catalytic hydrogenation.
