  • Patent number: 3934837
    Abstract: An improved web winder and compensator apparatus with automatic web winding speed compensating controls for selectively winding or unwinding at a uniform tension a roll of traveling continuous web material being selectively fed from or taken up by an associated mechanism, as follows. A tension compensator device passes the traveling web therethrough and compensates for variations in speed of travel of the web for maintaining a uniform tension therein. The compensator device preferably includes stationary rolls for guiding the web through the compensator device and counterbalanced movable rolls for receiving the traveling web therearound and for moving toward and away from the stationary rolls for decreasing and increasing the length of the path of travel of the web through the compensator in relation to the tension on the traveling web. The movable rolls are preferably movable to a threading position for straightline linear threading up of the web through the compensator device.

  • Patent number: 3934617
    Abstract: A jacketed pipe assembly of inner and outer tubular members having respective inner and outer corrugated metal tubes arranged in spaced relationship to define therebetween a fluid-circulating chamber adapted for the circulation therethrough of a temperature controlling fluid for aiding in the flow of a processing fluid through the inner tubular member. Coupling sleeves are connected by continuous welds to opposite ends of the inner corrugated tube, and means are connected to the outer ends of the outer corrugated tube and to the respective coupling sleeves to define therebetween respective opposite ends of the fluid-circulating chamber. The continuous connecting welds are surrounded by the fluid-circulating chamber, but are isolated therefrom by being enclosed within respective enclosures which are vented exteriorly of the pipe assembly so that cross-contamination between the inner corrugated tube and the surrounding fluid-circulating chamber will be prevented in the event of rupture of the continuous welds.

  • Patent number: 3933013
    Abstract: The panty portion of the panty hose is knit of stretch and spandex yarns to provide compressive force against the body of the wearer. The panty portion includes an attractive pattern of relatively opaque areas and open lace areas with alternate courses being knit of spandex yarn and intervening courses being knit of main and auxiliary stretch yarns. The spandex yarn is knit in every wale of the opaque areas and is selectively knit and tucked in the open lace areas. The main stretch yarn is knit in every wale of both the opaque and open lace areas while the auxiliary stretch yarn is knit in plated relationship with the main stretch yarn in the opaque areas and is floated in the open lace areas.

  • Patent number: 3931786
    Abstract: Method and apparatus for evenly coating a moving web of material with a predetermined amount of a liquid and characterized by simplicity of design, uniformity of application of the liquid and accurate control of the amount of the liquid applied, as follows. Mechanisms are provided for supplying and feeding a web of material in a longitudinal path of travel at a predetermined speed. A coating roll is positioned for transverse rotating contact with one surface of the traveling web of material and includes a covering of soft, uniformly and highly absorbent material for receiving and uniformly absorbing the coating liquid and for transferring and uniformly coating the traveling web with the liquid. An open top pan is provided for continuously receiving the coating liquid therein. The coating roll rotates within the pan for contacting and continuously absorbing all of the coating liquid within the pan above the level of the coating roll.

  • Patent number: 3930933
    Abstract: A debonded cellulose fiber pulp sheet that is adapted to be fiberized by mechanical action to form a fluffy material and is impregnated with small amounts, such as 1% or less, of a long chain fatty alkyl cationic compound having at least 12 carbon atoms in at least one alkyl chain and a similar small or somewhat larger amount of an oily material such as a mineral, vegetable or animal oil which coacts with the cationic compound to render the pulp sheet easily mechanically fiberizable, and the resulting fiberized fluffy material softer, more lofty and more absorbent and method for producing said sheet.

  • Patent number: 3930461
    Abstract: An apparatus for pivotally mounting an outboard fishing motor, such as a shaft-mounted submersible electric motor, on the bow of a fishing boat or the like for pivotal movement between an operative position wherein the motor is held in the water and a non-operative raised position. The apparatus comprises a pivotally mounted bracket for supporting the shaft of the motor, a semi-circular guide member fixedly positioned adjacent the bracket, a follower interconnecting the bracket and guide member, and a power control system including a reversible electric motor and cable arrangement for automatically and positively pivoting the fishing motor in either direction between its operative and non-operative positions by translating the follower along the guide member.

  • Patent number: 3930285
    Abstract: An apparatus and method wherein a tow of continuous filaments is fed to a tow cutter and severed into fibrous material of predetermined staple length while the fibrous material delivered from the tow cutter is fed to and through at least one textile picker. The fibrous material may be formed into laps at the picker for being subsequently processed through cards, or the fibrous material may be fed in loose fibrous form from the picker to a bank of cards. Means are provided for automatically controlling operation of the tow cutter and pickers and for controlling feeding of the fibrous material to the pickers.
