  • Patent number: 4241099
    Abstract: Pectin containing gelled products are provided such that their gelling is delayed for an enhanced length of time, adequate to permit the deposition or filling of the formulation into molds or containers before gelling proceeds. The products and method by which they are prepared more efficiently use pectin in a delayed gelation process by allowing setting at the optimum gelling pH in order to prepare final products of a desired gel strength with minimal quantities of pectin. A delayed-action or time-release acidulant is used in the method and is incorporated into the formulations and products of this invention, such acidulants including anhydrides, esters, lactones, and combinations thereof.

  • Patent number: 4239591
    Abstract: A non-laminated paper sheet product characterized by regions or islands of increased thickness, usually located in the center of the sheet for more economical use of the paper product and for conservation of wood pulp. The regions of increased thickness are formed by depositing or laying additional pulp stock onto a generally uniform thickness paper web in the web-forming area of a paper machine in either wet or dry methods of paper production. Continuous regions of increased thickness in the web can be formed by corresponding variations in the width of the web or by spraying the additional pulp onto the forming web. Islands of increased web thickness can be formed by periodically interrupting pulp stock depositing sprayheads disposed at spaced locations across the width of the forming web, with timing devices or web thickness sensors controlling the sprayheads.

  • Patent number: 4234847
    Abstract: An automatically resettable fault indicator includes a rotatably-mounted target viewable from the exterior of the indicator for indicating circuit status. The target is positioned in a reset-indicating state by a reset circuit which periodically energizes a first winding to position a permanent magnet mounted for rotation with the target. Upon occurrence of a fault circuitry within the indicator energizes a second winding to reposition the target to a fault-indicating position. A delay circuit in the fault-responsive circuitry prevents simultaneous energization of the first and second windings, and an auxiliary pole piece associated with the main pole piece assists in repositioning the target to the fault-indicating position, for improved performance and reliability in responding to fault currents.

  • Patent number: 4232828
    Abstract: A manually-actuated spray head for a liquid container includes a housing within which an insert is provided to establish a liquid flow path through the housing. One end of the insert is compressed by the housing to form a nozzle through which liquid is dispensed from the spray head. The other end of the insert is provided with a flange for sealing engagement with the container. A rotor rotatably driven by a user-actuated trigger compresses the center portion of the insert to force liquids through the nozzle under pressure. Since the entire liquid flow path of the spray head is defined by a replaceable insert construction of the housing is simplified and contamination of subsequently sprayed liquids can be avoided by changing the insert.

  • Patent number: 4228001
    Abstract: A method and apparatus is provided for removing contaminants or for recovering valuable minerals in trace amounts by ion exchange treatment of liquids such as municipal and industrial waste waters, ore mining and processing tailings, and the like as they flow through a resin bed wherein ions in the liquid are sorbed into the resin by an ion exchange mechanism. The resin bed is a folded, moving bed which exhibits all of the advantages of a packed ion exchange resin bed. Laminar flows are developed throughout the moving bed system to maintain all interfaces intact, even during the rinsing operation, while the moving bed used is of a "folded" type having a maximum height approximately one-third that of conventional countercurrent units. The ion exchange treatment occurs within a loading vessel resin bed, the beads in the feed portion of which become exhausted and sequentially move out of the loading vessel for subsequent regeneration and rinsing, followed by eventual return to the loading vessel.

  • Patent number: 4224398
    Abstract: A photopolymerizable system is provided as a latex system that is an oil-in-water polymer emulsion including particulates of water-insoluble polymers in combination with a water-soluble or water-dispersible, light-sensitive polymer having multiple light-sensitive moieties. Prior to coating onto a substrate, the system is a three-phase precursor emulsion of the emulsion particulates, the water phase, and the light-sensitive polymer. After coating, the bulk of the water phase is evaporated off, leaving a two-phase system of the emulsion particulates surrounded by the light-sensitive polymer. When selected areas are subjected to actinic radiation, a water-insoluble matrix is formed, the matrix containing cross-linked light-sensitive polymer having dispersed therethrough and/or included therein the water-soluble polymer particulates, thus forming oleophilic image areas.

  • Patent number: 4223508
    Abstract: A chub packaging machine, or the like, incorporates a double-knife cut-off or severing device of the invention. Chub packages are elongate tubular packages which are gathered at their opposed ends and have metal clips clinched therearound to close those ends. The double-knife cut-off device is mounted on the closure head assembly of a conventional chub packaging machine, with appropriate modification, and produces a shorter and cleaner stub end on a chub package than heretofore available. The appreciable amounts of product trapped in the stub ends of chub packages formed on conventional chub machines are substantially eliminated by shortening the stub ends to approximately one-third the usual length. The double knife cut-off device severs a short gathered portion of the tubing between two packages at two spaced apart positions rather than in the center of the portion as heretofore known.
