Abstract: PAPER MANUFACTURING STRUCTURE PARTICULARLY      FOR DETACHING A WEB FROM A WIRE                  ABSTRACT OF THE DISCLOSURE     A paper machine has a forming wire loop which trans-ports a web to a detachment transfer roll situated inside said wire loop at a detaching location where the web is to be de-tached from the wire and transported to a press section.          A relatively dry felt engages the web on a sector of the de-tachment transfer roll at the detaching location and receives the web from the wire and continues to transport the web, while it adheres to the felt, to the press section.  The detachment of the web from the wire on the detachment transfer roll is facilitated by the centrifugal force acting on the web which results from the substantial change of direction undergone by the web on the detachment transfer roll.  In one embodiment, the press felt is directed to cover the web on a sector of the detachment roll by a press suction roll located on sub-stantially the same level as the detachment transfer roll, the press roll having a suction sector which facilitates trans-fer of the web from the wire to the felt.

Abstract: PRESSURE-SENSING CAPACITOR AND   METHOD OF TRIMMING SAME                      ABSTRACT       A pressure-sensing capacitor and a method for trimming the capacitor is disclosed.  The capaci-tor includes a pair of spaced flexible quartz plates. A thin circular layer of conductive metal is formed on the opposing inner surfaces of the plates to define the electrodes of the capacitor.  A glass frit sealing compound, forming a concentric ring about the conductive layers, is disposed between the plates to seal the evacuated space between the plates.  The thickness of the ring is small enough so that the capacitance be-tween the electrodes is higher by an unknown amount than the desired value of capacitance at every point in the range of variation of the value of pressure.  The capacitor is trimmed by first measuring the capacitance value at zero pressure.  In two of the embodiments disclosed the capacitance value at a maximum pressure is also measured.  The dimensions and location of a path on one of the electrodes is computed from a measured capacitance value(s) and the deflection characteristics of the plates.  Radiant energy in the form of a laser beam is applied to the electrode to cut through the electrode along the computed path to electrically insu-late a first part of the layer from a second part of the layer so that the value of capacitance at zero pressure is substantially equal to the desired value.

Abstract: : Method and apparatus for forming a stackable tray from a paperboard blank having a base panel, two pairs of wall panels attached to the base panel, adhesive coated gussets formed at the corners of the wall panels, and flanges formed along the outer edge of each wall panel. The tray forming apparatus includes a vertically reciprocating plunger having vacuum ports formed in its side walls, two pairs of flange folding fingers mounted on the plunger, a forming head including a cavity disposed beneath the plunger, and a stacking cage having flange retaining rails disposed beneath the cavity for receiving the trays after forming. the trays are formed as follows: A tray blank is first positioned over the forming cavity. The downwardly reciprocating plunger contacts the blank and urges it into the cavity causing the tray sidewalls to be erected and the adhesive coated gusset corners to be folded against adjacent side walls. the erected tray walls are retained on the plunger by the vacuum ports. The flange folding fingers are actuated by linear cams, with first one pair of flanges being folded and then the other with the flanges being folded outwardly and downwardly with respect to the tray walls into an overbroken position until the flanges lie at an acute angle to the tray walls. At the bottom limit of the travel of the plunger, the formed tray is ejected into the stacking cage which is dimensioned to retain the flanges of the trays in the overbroken position and the tray is nested in the stack of previously formed trays so as to hold the gusset corners securely against the tray walls for a time sufficient to allow the adhesive to set. The folded flanges lend stiffness to the upper edges of the tray walls and allows the trays to be nested in the stacking cage. The flanged tray can be later sealed with a lid.

Abstract: A B S T R A C T         An elongated approximately C-shaped frame with a handle portion above an elongated hand hole has downwardly-projecting arms depending from its forward and rearward ends.          The forward arm is bifurcated by being keyhole-slotted verti-cally into a pair of laterally-spaced L shaped fingers which straddle the spike and the tubular spacer surrounding it with-in the gutter.  The rearward depending arm is provided with an impact abutment for receiving the hammer blows during use.          A strenghtening rib extending along the body between the de-pending portions imparts rigidity to the frame. In the  first stage of its use. the forward depending arm is moved over the top of the gutter and dropped around the tubular spacer, then pulled toward the use until the flat ends of the fing-ers engage the inner surface of the outer gutter wall directly beneath the spike.  A hammer blow on the abutment on the rear-ward arm pulls spike, spacer and gutter bodily a short dist-ance away from the building wall to which they are attached.          Thereupon the device is lifted out of the gutter, which is then pushed back toward the building wall to space the head of the spike and the adjacent portion of its shank away from the forward wall of the gutter.  The forward arm of the de-vice is then dropped around this projecting portion of the spike and pulled backward against its head, whereupon hammer blows against the abutment cause the spike to be pulled com-pletely out of the gutter and tubular spacer, which drops into the gutter.

Abstract: Abstract of the Disclosure A reactive polyurethane mixture is applied by a high pressure airless spray applicator directly onto the primary backing of a moving substrate such as a carpet web,  The applied reactive mixture is allowed to foam to an approximate predeter-mined thickness and density.  While the blown or foamed backing layer still possesses substantial residual tackiness, it is compressed or regauged to a precise uniform thickness and simultaneously is provided with either an embossed or a smooth surface.  The tack of internal cell walls of the blown backing layer retains the layer at the regauged thickness.  Curing of the regauged backing layer by externally applied heat and/or by the heat of the exothermic reaction in the applied mixture is completed.  Detackifying agents are applied to the regauging devices and/or to the applied backing layer to prevent adherence of the layer to the regauging devices.  A surface skin formed of the detackifying agents is cured on the regauged backing layer.          The process achieves a great savings of energy and is fast and economical.
