  • Patent number: 4427759
    Abstract: Process for preparing flexographic photopolymer elements by passing into the nip of a calender a photopolymer composition mass comprising elastomeric binder, monomeric compound, and photoinitiator and calendering the photopolymer composition either between (1) a support and multilayer cover element consisting essentially of a flexible cover film, optionally a flexible polymeric film, e.g., polyamide, and a layer of elastomeric composition which is photosensitive or becomes photosensitive during or after calendering, or between (2) two supports, one of which is removed prior to contact, e.g., by lamination or pressing, with the multilayer cover element. The flexographic photopolymer elements are useful for flexographic printing, e.g., dry-offset, letterpress printing.

  • Patent number: 4427758
    Abstract: A high speed, positive-working photopolymer element comprising, in order: (1) a support, (2) a nonphotosensitive layer comprising a hardenable binder (e.g., gelatin) containing a releasable hardener (e.g., glutaraldehyde-bisulfite), and an optional colorant, and (3) a permeable photopolymerizable layer. Imagewise exposure of the photopolymerizable layer is followed by diffusion of an alkali through the nonimage area, releasing the hardener. A subsequent wash-off step produces a positive image of the original.

  • Patent number: 4426933
    Abstract: A detonator closed at one end by a primer shell whose integrally closed end has a percussion-sensitive primer charge supported adjacent its inside surface, and its outside surface disposed across the end of the detonator shell, is actuated by the detonation of one or two lengths of low-energy detonating cord (LEDC) adjacent the primer shell's outside end surface, a single length of LEDC being arrayed in a manner such that a pair of axially separated segments thereof, or two lengths arrayed in a manner such that a segment from each length, is anchored in place in side-by-side relationship adjacent said surface. This cord array assures reliable ignition of a center- or rim-fired percussion primer by means of the side-output of LEDC even with explosive core loadings at the low end of the LEDC loading range.

  • Patent number: 4426174
    Abstract: An annular hollow support telescopically receives an annular hollow body in which is molded a longitudinally extending cylinder embedded in a frangible mass. The support includes an annular flange to seat and position the hollow body so that the hollow body projects longitudinally of and from the support and a surface is associated with the support to position the support on a marine structure so that the support projects laterally from the marine structure. Jack means are connected between the support and the annular hollow body for assisting in removing the annular hollow body and supported cylinder relative to the support.

  • Patent number: 4426501
    Abstract: Copolymerization in aqueous emulsion of ethylene with one or two comonomers having different water solubilities is more efficient when at least two but no more than three comonomer solubility-affecting additives are present in the copolymerization medium, at least one of which increases the solubility in water of one of the comonomers, while at least another one decreases the solubility in water of another comonomer. In this manner, the diffusion rates of comonomers to the copolymerization locus are well controlled; the rate of polymerization often is increased; the concentrations of the comonomers at the copolymerization locus remain constant; and the copolymer composition remains constant. This process improvement can be applied to the copolymerization of many comonomer combinations of great commercial interest, including, for example ethylene/tetrafluoroethylene and ethylene/ethyl acrylate copolymerizations.

  • Patent number: 4426400
    Abstract: Deviled eggs are prepared by an improved method, starting with a blended mixture of liquid egg whites. The mixture is evacuated to remove air and other gases, then dispensed into a multiplicity of open molds carried on conveyor means, said molds shaped like half an egg and of similar size. A second mold is positioned centrally in the first mold to make a cavity in the egg white similar in shape and size to half an egg yolk. The egg white is cooked in steam at atmospheric pressure, then cooled, and removed from the mold. Into the resulting cooked egg whites is dispensed a mixture of cooked egg yolk and seasonings, yielding the desired deviled egg product.
