Abstract: Protective eyewear that incorporates standard near-point corrective lenses into a protective shield. The protective eyewear, which includes side-protective shields, is fabricated from lightweight, transparent impact-resistant material. The corrective lenses are incorporated in the lower portion of the shield, thereby leaving the upper, larger portion of the shield uncorrected and thus available for viewing distant objects. The corrective lenses provide a focal length within a range commonly associated with reading glasses.

Abstract: A device for protecting bows on gift-wrapped packages and the like. The device consists of two main components: a cup and a shield. The cup is of a type otherwise useful for drinking or eating ice cream from that has had its bottom portion cut into a number of pie-shaped segments all pointing to the center. The pie segments are flexible so that one can push the cup, bottom-first, over the bow to be protected, without harming the bow. Similarly, when the bow is to be displayed, the cup can be pulled back over the bow gently. The shield component extends across the otherwise open top of the cup, so as to provide protection against rain and other assaults on the bow from above. Operating together, the cup and the shield, when the device is slipped down over a decorative bow can protect the bow from becoming soiled or crushed, with special application to providing such protection when the package bearing the bow is wrapped for transportation, either across town or from one city to another.

Abstract: A control system for controlling the pressure and pressure balance in two separate fluid pressure circuits. A valve being employed which comprises a balance piston and a regulating piston. Each of the pistons controls a connection of the first and second fluid pressure circuits to a respective relief line. Fluid pressure is applied to the regulating piston to regulate the pressure in one circuit and the balance piston regulates the pressure in the other circuits in relation to that regulated by the regulating piston. A three position switch and two air pressure regulators or a three position switch, two potentiometers and a servo control valve control the pressure applied to the regulating piston to control the pressures required in the first and second circuits for the desired modes of operation. A further balance valve may be disposed between the first and second circuits.

Abstract: A twin wire papermaking machine which has a multichambered suction dewatering device located over the forming wires downstream from the forming roll. The dewatering device deflects the forming wires into a concave path to aid in formation and dewatering.

Abstract: A holder for rotatably mounting the metering rod in a rod-type web coating apparatus, such as used to coat paper, is made of a rigid but yieldably deformable material, such as a plastic. The holder includes a plurality of longitudinally extending conduits for carrying water to lubricate the rotating rod and removing coating particles which are carried by the rod from the web surface and into the rod cavity. The holder has a surface opposite the rod cavity for receiving a uniformly applied load along the longitudinal length of the rod holder for aligning the rod surface and/or applying a uniform nipping load between the rod and surface of the web being coated. A second surface also extends longitudinally for the length of the holder along a lip portion which protrudes from one side of the cylindrical rod cavity.

Abstract: Method and apparatus for pulping and grading waste paper in which stock is introduced through a central inlet in one end wall of a cylindrical chamber and accepts are discharged through a perforate screen in the opposite end wall. An impeller in the chamber adjacent the perforate screen provides for pulping and pumping of the stock as well as provides rotational movement of the stock within the chamber. Light rejects are continuously removed through an outlet adjacent the wall containing the perforate screen while heavy rejects are removed through an outlet adjacent the inlet wall.

Abstract: A method and apparatus for texturing, softening and building bulk into a non-woven fabric web, such as tissue or toweling paper, wherein the paper is passed through a plurality of nipped rolls while interposed between a pair of screens. In the preferred embodiment, each screen is comprised of metal and plastic shute and warp strands, respectively. The web is passed through a first texturing nip while wet and then dried before passing through subsequent nips to effect the texturing and softening of the web.

Abstract: A steam heated dryer drum having one or more spoiler bars secured against its inner shell wall to extend longitudinally and substantially parallel with the axis of rotation. The spoiler bars generate turbulence in the condensate to lower the resistance to heat transfer through the shell wall. No screws, bolts, rivets or the like, which would necessitate penetration of the shell wall, are required or used to secure the bars. In one embodiment, the bars themselves have a bridge-shaped cross sectional configuration and are made of a magnetic material. Their bridge legs form the north and south poles of the magnetic bar and have their ends contoured to correspond to the drum shell radius of curvature.In another embodiment, magnets having a bridge-shaped cross section are used.

Abstract: A press structure for performing a dewatering operation in the steps of formation of a traveling fibrous web such as in a paper making machine wherein the wet web is carried on one or more water absorbing felts through a press formed of a pair of extremely tough liquid impervious belts with the belts backed throughout a pressing zone by a series of fluid pressure chambers applying hydraulic pressures to the back of the belt. The chambers are arranged so that a first fluid pressure is applied at a first portion of the pressing zone, and subsequently a second higher pressure is applied to the belts at a second portion of the pressing zone and thereafter a third pressure is applied at a third portion. Each successive pressure is higher than the previous one so that the hydraulic resistance pressure of the moisture leaving the web does not build up at such a rate so as to disrupt the web fibers.

Abstract: A device for positively positioning a tubular workpiece on a carrier, and in particular for positioning a tubular parison on a carrier of a conveyor within a parison heating oven. The parisons are engaged by a cam operated positioning cap which exerts a downward force on the top of the parison to position the parison on its carrier member.
