Abstract: PAPER COATING METHOD AND APPARATUS            Abstract of the Disclosure This invention relates to a method, and apparatus of the blade type, for applying a coating material to a web of paper.      A conventional coater of the blade type includes means for applying coating to a paper web supported and carried by a resilient backing roll, together with a flexible doctor blade located some distance from and on the trailing side of the applicator, which serves to level the applied coating.      In order to achieve low coat weights, i.e., in the order of  3 to 4.5 grams per square meter per side of paper, it is necessary to increase the pressure of the blade against the web, which results in a high rate of wear, and increases the possibility of web breakage and streaking caused by foreign particles being caught between the blade and the web.      The present invention utilizes a reservoir of liquid coating material between a forward liquid seal and a rearward doctor blade spaced a short distance from the seal.  The coating material is applied under pressure to as to form and maintain the liquid seal.  This provides a short dwell time, low coat weights, low blade pressures, and excellent results.          Figure 5 is representative of the invention.

Abstract: ABSTRACT OF THE DISCLOSURE     A novel method is provided of making a book cover including a pocket element wherein a continuous web of cardboard material and a con-tinuous web of paper material are supplied to a work station where they are adhered to each other along their lateral edges.  The composite web which is formed is then longitudinally slit at three spaced-apart loca-tions to separate the composite web into first and second composite sec-tions and to form pocket elements on each of the composite sections.  These composite sections are then cut in a transverse direction at spaced intervals to form first and second book covers, wherein each of the book covers includes its own pocket element adhered thereto.  In this way, a continuous method is provided for mass producing book covers which include the pocket elements.  In addition, the hinges for allowing the book cover to expand are included in the continuously-processed web.

Abstract: ABSTRACT (Figure 1) The device for feeding sheets (F) of wrapping material to packaging machines comprises a feeding group (11, 12, 26, 27) operating intermittently, driven by independent electric motors (24, 28) controlled in synchronism with the operating frequency of the packaging machine by a programmable electronic control circuit (40 -- 53). The sheets (F) are individually cut the one after the other from a continuous web (N) unreeled from a roll (B) which is driven into rotation by an electric motor. The web forms a buffer loop (A) and passes through a pair of intermittent-feeding rollers (119 12) from which it is fed to a cutter (26, 27) of the rotary alternating type. Both the intermittent-feeding rollers (11, 12) and the cutter (26, 27) are driven by separate independent electric stepping motors (24, 28). The programmable electronic control circuit (40 - 53) establishes for each single motor a determined law of motion, variable at will.

Abstract: ABSTRACT OF THE DISCLOSURE        The specification of the present invention discloses a rotary bore hole enlarging bit used in forming bore holes in the earth's surface.  The enlarging bit comprises an elongate mandrel member having a central opening therethrough; a body member reciprocable on the mandrel member; and a piston chamber on the mandrel member and body member for shifting the body member in one longitudinal direction.  The mandrel member has an inlet passage leading to the piston chamber and either the mandrel or body has a plurality of circumferentially spaced cutter supports thereon.  An expander is provided on the other member and the cutter supports for expanding the cutter supports outwardly upon movement of the body member on the mandrel member in one longitudinal direction.  A fluid passage in the body member and cutter supports leads from the piston chamber and exits from the cutter supports.  The passage is of relatively small flow area when the cutter supports are retracted and large flow area when the cutter supports are expanded to maintain a relatively high pressure in the piston chamber during expansion of the cutter supports; and cutter elements on the cutter supports.  After the cutters arefully expanded, additional air is utilized to clean and cool the cutters.
