Abstract: A process for the production of a multicolor reversal image with improved color balance is provided which process comprises the steps of directing incident image light dot- or linewise modulated by a light-distributing means onto a multicolor photographic silver halide emulsion material containing a blue-, a green- and a red-sensitive silver halide emulsion layer and processing said silver halide emulsion layers to form a color reversal image.In the maximum density part of the dots or lines of said light distributing means e.g. a contact screen the ratio of the absorption density for the light corresponding with the spectral sensitivity region of the silver halide emulsion layer being during the exposure most remote from the light-distributing means to the absorption density for the light of the whole visible spectrum (400-700 nm) is higher than the said ratio in any other density part of the dots or lines (see FIG. 1).

Abstract: Flame retardant, char-forming, flexible polyurethane foams are described which include, in addition to suitable diisocyanates and other basic foam-forming components, a flame retardant material and a polyol which has substantially non-reactive hydroxyl groups with respect to the diisocyanate component under the conditions of the foam-forming reaction. Accordingly, the polyol remains in the finished polyurethane foam substantially unreacted. When the finished foam product is subjected to combustion conditions the flame retardant material and unreacted polyol combine to retard flame formation and to provide a dripless char. In addition to the flame retardant and char-forming characteristics, the flexible polyurethane foam is firm, permitting the manufacture of clickable foams.

The process is characterized in that at least 0.1, preferably 0.2 to 1.5, moles/kg of phosphor in the form of a polyphosphoric acid and/or an acidic phosphoric acid ester of mono- or polyhydric alcohol based on the polyacid of the final product is esterified with the other reactants in a 40 to 80 percent by weight of solids containing solution of one or more diluents inert towards the raw materials employed.

Abstract: An airspeed sensing post includes a static pressure sensing device having such a revolutionary shape that when the incidence angle varies, the fluid flow arriving near said sensing device is always the same and along a surface having the same contour. Thus, the aerodynamic conditions are always the same when the direction of the fluid flow varies. So, no correction of measured static pressure is required in dependence of the pitch angle.

Abstract: This invention relates to the joining of two metal sheets such as in the repair of automobile body components. There is provided a tool which may be utilized to first form a dimple in one or more sheets, and then form a bore through the one or more sheets in alignment with the dimple so that the head of the fastener utilized to join the sheets may be recessed within the dimple and covered by a suitable filler material to provide a flush surface. The tool and the method of utilizing the same are particularly adaptable for securing together sheets utilizing conventional pop rivets.

Abstract: Each ceramic fiber block is temporarily supported by a supporting member and bar combination previously secured to the furnace casing, before it is finally secured to the casing by another supporting member and bar combination. No separate means for holding the block temporarily is required. As ceramic fiber blocks and supporting members are alternately attached to the casing, it is possible to ensure intimate contact between every two adjoining blocks. The absence of any extra work for holding the blocks temporarily improves the efficiency of the block installation work.

Abstract: Mold and core rod combination for forming a plastic parison for stretch/blowing into a plastic bottle comprising a core rod with an end mated to the mold so as to permit formation of a parison with a flat on the bottom and having a sharp taper from said flat to the sidewall of the parison. The core rod is preferably shaped to include a shoulder having a substantially straight outer wall at the mouth end of the parison mold, and constructed and arranged with the mold to permit deposit of additional plastic at the inner wall of the shoulder of the parison. The design of the mated mold and core rod combination is based on the recognition that in a continuous bottle forming process a particular area of the parison can be made hotter or cooler by increasing or decreasing the thickness of that area of the parison.
