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.

Abstract: A method and system are described for preventing interaction between the valves and pump in a liquid blending system. The method and system select operating relationships between the valve period and pump period that avoids synchronous operation and thereby improves the blend accuracy.

Abstract: An automatic continuous gluing machine for the application of the glue onto he border of a panel being coated is described. The machine eliminates the necessity of pregluing the coating strips because it provides for the application of glue both on the panel and onto the strip, while the panel advances along the plane of operation. The machine is provided with lamps and a jet of hot air to heat the panel and the strip respectively, and pressure rollers to hold the panel and strip adhering to each other.

Abstract: A process for preparing concentrated slurries of TiO.sub.2 and water with a solids content of 30-70% by weight from TiO.sub.2 micronizer tailings that are carried in steam separated from TiO.sub.2 and steam from a micronizer by scrubbing the steam and TiO.sub.2 micronizer tailings with a slurry of TiO.sub.2 and water, separating TiO.sub.2 and water from the steam and circulating a portion of the TiO.sub.2 and water to the absorber until the solids content desired is reached.

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.

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.

Abstract: A process is described for printing dyes onto a textile material comprising the steps of forming a latent magnetic image in a magnetic imaging member comprising a ferromagnetic material on an electrically conductive support; developing the magnetic image by applying a ferromagnetic toner comprising a ferromagnetic component, a dye component which is substantially sublimable at from 160.degree. C. to 215.degree. C.

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.

Abstract: Described are high-solids solutions of diol/higher polyol/aromatic acid/aliphawtic acid branched polyesters of carefully controlled composition and suitable as components of organic coatings.

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.

Abstract: Novel hydraulically entangled spunlaced fabrics and an improved process for making such fabrics composed of at least two types of staple fibers are provided. Elastomeric staple fibers which behave as ordinary staple fibers until heat treated are included in the hydraulically entangled fabric. Upon heat treatment, the elastomeric fibers become elastic and impart improved stretch and resilience properties to the fabric.

Abstract: Quinacridonequinone pigments photostabilized with from 2.5 to 20 wt. % Mn(OH).sub.2 are disclosed. The Mn(OH).sub.2 is precipitated on the pigment from an aqueous solution of a divalent manganese salt by either adding a base or adding urea to the salt solution and heating.

Abstract: An apparatus for applying toner to an imagewise tacky surface on a photo-element. The element advances through the apparatus between a pair of plates covered with pile fabrics. The pile fibers are slanted in the direction of advance. One of the plates carries a hopper filled with a particulate toner and one is reciprocated to impart movement to the element.

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.
