Abstract: ABSTRACT OF THE DISCLOSURE An improved wire reinforced corrugated product, i.e., paper, is provided herein.  It includes support means having a plurality of spaced parallel channels disposed therein.  A plurality of longitudinally exten-ding spaced parallel metal wires is disposed in the channels of the support means, the depth of the channels in the support means substantially corresponding to the height of the wires disposed herein and the width of each of the channels being at least equal to the total width of the wires disposed therein.  The support means and the wires are corrugated transversely of the longitudinally extending wires.  The wires are thus firmly held in place in the channels so that slippage of the wires  which leads to tearing, ripping or shredding of the paper is inhibited.

Abstract: ABSTRACT OF THE DISCLOSURE         A take-up and pay-out device for tow cables of tow lifts having a return spring for the tow cable wound onto a tow cable drum and a centrifugal brake that has at least one centrifugal weight for the tow cable drum.  In that area closest to the axis the centrifugal weight has a braking surface that extends in the manner of a cam, this engaging the inside wall of the housing when the tow cable is paid out, whereas a rotatable brake shoe is arranged in that area of the centrifugal weight furthest from the axis, this moving into the operating position, i.e., in contact with the inside wall of the housing, automatically when the tow cable is taken up and simultaneously the cam-like and projecting braking surface, simultaneously lifting the inside wall of the housing.  Thus, when the tow cable is paid out there is a powerful braking effect, and when the tow cable is taken up there is  a somewhat less braking effect on the part of the centrifugal brake.

Abstract: "METHOD OF SEPARATING OIL OR BITUMEN   FROM SURFACES COVERED WITH SAME"                   Abstract of the Disclosure The separation of oil or bitumen from  a surface of a substrate covered with same is effected by dissolving the oil or bitumen in a solvent to form a solution thereof.  A liquid which does not dissolve the oil or bitumen, is non-miscible with the solvent and has substantially higher surface wetting properties than the solvent on substrate is intimately contacted with the surface of the  substrate; the solvent and liquid have substantially high interfacial tension relative to one another so as to form in the presence of the oil or bitumen an interfacial membrane-like barrier which is impermeable thereto. The intimate contacting of this liquid with the surface of the substrate causes the liquid to wet the surface and spread thereover to thereby move the interfacial membrane as it is being formed across the surface and displace with this membrane the solution from the surface, and to finally cover the surface with a layer of liquid; the membrane maintains the oil or bitumen in the solvent and prevents passage of same into the layer of liquid.  The method of the invention avoids the use of surfactants and the forma-tion of emulsions, and thus the problems associated there-with.  The invention finds a particular application in the recovery of oil and bitumen from bitumen covered tar sands and oil sands from oil wells.

Abstract: ABSTRACT OF THE DISCLOSURE        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. The invention also employs an overload mechanism which prevents excessive force from being applied to the gears in the event the dispenser becomes jammed.
