  • Patent number: 4278287
    Abstract: A folding seating piece, preferably in the form of a chair (10) includes pivotally interconnected frames (12, 14 and 16) forming a seat, backrest and armrests. A frame member (28) of the seat adjacent each side of the chair includes a snap fastener (40) connected thereto; each of said fasteners including a laterally extending guide section (46) and a downwardly directed clip section (48). The guide section of each clip overlies an adjacent frame member (34) for engaging, and being adapted to move along the adjacent frame member as the chair is being pivoted into its open position.

  • Patent number: 4265409
    Abstract: An apparatus that controls the swinging of a frame (50) and the rotation of a turret (52) in an automatic web rewinding machine. The frame (50) is pivotally mounted in the machine and a turret (52) including a plurality of rotatable mandrel assemblies (56) is mounted for rotation within the frame (50). The control apparatus includes an indexing device (66) having an output shaft (70) that undergoes intermittent rotation in response to continuous rotation of an input shaft (68). One drive means (80), coupled and responsive to the output shaft (70) of the indexing device (66) provides intermittent rotation of the turret (52). A second drive means (78) is provided to control the rotation of the cam (60) in order to minimize the overlap of the rotation of the cam (60) with the dwell time of the turret (52). The optimum condition occurs when the cam (60) rotates only when the turret (52) is indexing and when the cam (60) does not rotate at all while the turret (52) is dwelling.

  • Patent number: 4259082
    Abstract: Sodium sulfate crystals, also known as salt cake, are obtained as a side stream in the manufacture of chlorine dioxide by the reduction of sodium chlorate with chloride ions in an aqueous, acidic medium containing sulfate ions. The sodium sulfate crystals are contained in a mother liquor saturated with sodium sulfate and contaminated with chloride ions. The process provided by the present invention purifies the salt cake crystals by separating the crystals from the mother liquor without evaporation of the mother liquor until a critical dryness level is achieved and then the remaining mother liquor is evaporated to result in purified salt cake crystals having substantially reduced chloride ion content.

  • Patent number: 4248521
    Abstract: An improved electrographic recording apparatus and method. An electrographic recording medium has a charge retaining front surface on which charge is distributed in a pattern representing a desired image to be recorded, and a field permeable conductive layer. While charge is being deposited on the charge retaining surface of the electrographic medium, a field is established and maintained behind the rear surface of the medium, said field penetrating the conductive layer and having a field strength on the charged side of the medium that opposes a field that causes charge to be deposited on the charge retaining surface of the medium. In another aspect of this invention, the recording apparatus has a toner application station that is located apart from the charge depositing means, and a second field, having the same polarity as the first field, is established and maintained behind the rear surface of the electrographic medium at the toner station.

  • Patent number: 4223677
    Abstract: An absorbent fibrous structure includes intermingled absorbent fibers of a varying length up to about 6.35 mm. These absorbent fibers are graded by length through the thickness of the structure so that long length absorbent fibers are more concentrated than shorter length absorbent fibers at a first surface of the structure, and the shorter length fibers are more concentrated than the longer length fibers at an opposing second surface of the structure. The grading of absorbent fibers by length provides a capillary gradient through the thickness of the absorbent structure wherein capillary pores are graded by size so that large capillary pores are more concentrated than small capillary pores at the first surface of the absorbent structure, and smaller capillary pores are more concentrated than larger capillary pores at the opposing second surface of the structure.The absorbent fibrous structure of this invention may be employed as an absorbent core of an improved disposable diaper.

  • Patent number: 4207367
    Abstract: A nonwoven, self-sustaining, absorbent fabric comprising a sheet of randomly arranged, intermingled cellulosic fibers has a plurality of high loft, loosely compacted regions separated from each other by highly compressed regions. An adhesive material penetrates through the compressed regions to form bonded fiber networks extending completely through the sheet, and said adhesive material only partially penetrates through said high loft regions whereby the fibers in the interiors of said high loft regions are unbonded by said adhesive so that said regions are highly absorbent. A method for manufacturing the above-described nonwoven fabric by moistening opposed surfaces of a loosely compacted, randomly oriented cellulosic fiber sheet, embossing said moistened sheet for providing a pattern in said surfaces, applying an adhesive to the patterned surfaces of the sheet and setting said adhesive.

  • Patent number: 4197970
    Abstract: An apparatus for transporting a recording medium, such as transparent electrophotographic film, which has a conductive layer, from a supply to a take-up roll. The apparatus includes a drive roller that has a conductive ring. The conductive layer of the film is maintained at a desired potential, generally ground, and a different potential is applied to the conductive ring of the drive roller. When the film contacts the periphery of the drive roller, an electrostatic attractive force is developed between the conductive ring of the drive roller and the conductive layer of the film, thereby allowing the drive roller to transport the film without slip.

  • Patent number: 4192442
    Abstract: A sheet material dispensing apparatus wherein the sheet passes through a nip formed by a drive roller and a pressure roller. A lever is mounted for rotation about a first point and a gear segment is mounted for rotation about a second point. When the lever is rotated, a point or surface on the lever slidingly contacts a point or surface on the gear segment causing the gear segment to rotate through a greater angle than the lever. The teeth of the gear segment are operably engaged with gear means which causes rotation of the drive roller. In another aspect of the invention, the gear means for rotating the drive roller includes a floating gear mounted in a slot that is aligned generally parallel to the teeth of the gear segment and which causes rotation of the drive roller during one direction of travel of the gear segment and is disengaged from the drive roller during the other direction of travel of the lever.
