Abstract: MULTICONSTITUENT OPTICAL FIBER               AND METHOD FOR PRODUCING SAME            ABSTRACT        Silica-based optical fiber comprising at least a core and a cladding surrounding the core, both core and cladding material produced by a vapor phase deposition process.  The core and/or the cladding comprise at least two substituents, one chosen from Li, Na, K, Rb, Cs, Be, Mg, Ca, Sr, Ba, and the 4f-type rare earths (the "modifiers"), and the other chosen from B, Al, Ga, In, P, As, and Sb (the "homogenizers").  The maximum concentration of the substituents in the fiber is such that 3 < (n1M+n2H)/H < 20, preferably < 10, where n1 and n2 are the valences of the modifier and the homogenizer, respectively, and M and H are the concentration, in mole %, of modifier and homogenizer, respectively.  Fiber according to the invention comprises at least 50, frequently more than 80% by weight, SiO2, and further has a maximum modifier concentration of at least 0.2 mole %, preferably at least 1 mole %.  The presence of homogenizer frequently permits achievement of modifier concentrations that lead to phase separation or crystallization in prior art fibers.          Disclosed is also a method for producing optical fiber, the method comprising forming a metal halide complex having a relatively high vapor pressure.  (Fig. 1)

Abstract: A B S T R A C T            This disclosure relates to a process for cross-linking polymers, e.g. polyethylene, or degrading polymers, e.g. polypropylene, using peroxides having at least one carbon-carbon double bond in the molecule, e.g. 1-(t-butyl peroxy isopropyl)-3-isopropenylbenzene. Incorporation of the peroxides into the polymer may be carried out at relatively high temperatures without the risk of premature decomposition of the peroxide, thus allowing easy processability of the polymer mass prior to cross-linking or degradation. The polymeric endproducts obtained are odourless and do not display blooming.

Abstract: SIGNAL MATCHING SIGNAL SUBSTITUTION                 Abstract of the Disclosure A signal matching signal substitution system includes a tuner for selectively receiving signals in respective television channels and an input gain control for controlling the signal output level of the tuner. The system substitutes television signals in a substitute channel in lieu of normal signals in a normal channel selected by a viewer.  The system has a component for determining the input signal level of currently received signals in a currently received channel and generating a current amplitude signal.  A set point generator is responsive to the current amplitude signal corresponding to the normal channel most currently received for providing a set point for the output signal level.  A gain control signal generator is responsive to the set point and the signal output level for generating a gain control signal maintaining the output level at the set point.  The set point may be set at a predetermined fixed level when the current amplitude signal corresponding to the most current normal channel is relatively high and is set at progressively lower levels when the current amplitude signal corresponding to the most current normal channel is below a transition level.  The set point at the progressively lower levels is noise limited to provide substantially equal signal to noise ratios in the signal output of the tuner in both the normal and the substitute channels upon signal substitution.  The set point is gain limited to the maximum signal output achievable by the gain control means for the normal channel.

Abstract: Side chocks 1 for an engine bed are produced by first welding longitudinal elements 3 with associated projecting reinforcement 4 firmly to the bed on both sides of the bottom frame of the engine, arranging two seals 9 between the bottom frame 7 and the element 3, so a volume closed off in the horizontal direction lies between the element and the bottom frame, and then filling this volume with epoxy resin which, after setting, provides a permanent and rigid connection between the bottom frame and the element 3. A great amount of work is saved by virtue of the fact that the longitudinal elements 3 do not have to be arranged with particular accuracy in relation to the bottom frame. <IMAGE>

The cross-sectional area of the bending zone increases progressively towards the lower end, whereby the flaring-out zone formed upon bending of the post will be larger below than above the line of bending. The greater inherent resiliency of the material below than above the line of bending will cause the post to bend back into an upright position after having been hit by a vehicle. Certain embodiments of the posts are manufactured by diagonally splitting lengths of extrusion-molded plastic tubing, forming two identically shaped posts from each tube length.

Abstract: The tape transport mechanism for a video recorder has a tape guide which is a part of a tape lead-in mechanism and during operation automatically sets the correct position of the magnetic tape 20. The deflection elements 8 belonging to the tape lead-in mechanism are designed as tilting or pivoting pins without side flanges, which guide the magnetic tape. These pins have a cylindrical or conical case which, in its centre measured in the axial direction, is point-suspended and is mounted movably in a plane in relation to the stationary inner part. The distance between the centre of the magnetic tape and the tilting point of the case, in association with the tape tension, defines the force components at right angles to the tape travel direction. In the main drum region, the magnetic tape is guided by guide pins 9, 10 which are arranged in a stationary manner in front of the point of entry and after the point of exit for the main drum at right angles to the tape travel direction. Close to their upper end, the guide pins have a flange, against which the upper edge of the magnetic tape bears for guidance in height. The pivoting pins ensure this automatically. The lower edge of the magnetic tape bears against a stationary guide 11 at half the wrap angle. The magnetic tape is not mechanically connected between the pivoting pins, and no expensive adjustable stop is required. <IMAGE>
