The object of the present invention is an absorbent paper product including at least three plies, and a method of manufacture therefore. The absorbent paper product is of an approximate specific surface weight between 36 and 105 g / m2, and includes at least three plies, namely a central ply and two embossed upper and lower outer plies each including salient patterns composed of at least in part discrete protrusions. The plies are joined by joining at least part of the protrusions of each of the outer plies to the central ply. At least one of the outer plies has a pattern density larger than 30 protrusions / cm2. The embossed lower outer ply (2) includes combined high and low patterns (5 and 7) of respective heights (H) and (h). The central ply (4) and the embossed upper outer ply (3) are joined in the nested mode to the embossed lower outer ply (2) at the level of at least part of the tops of the high pattern (5) of height (H) of the embossed lower outer ply (2).

The leaf guard for gutters is an elongated sheet of enamel coated aluminum adapted to fit over the rain gutter on a house in a manner that directs water flow from the roof into the gutter while preventing leaves and other debris from entering the gutter. In a first embodiment, the guard is formed into a planar section that is secured to a roof, a curved nose section extending from the planar section, a trough under the curved section and a cornered lip extending from the trough to secure the device to the outer rim of a gutter. In a second embodiment, the guard is formed into a planar section, an inwardly bent connection section that is connected to the inner rim of a gutter, and a curved nose section that hangs over the outer rim of the gutter. The guard also has rows of elongated slits in the planar section that permit some water to drip through to prevent bees and other insects from nesting beneath the device. The device is bendable such that the slope of the planar section can be changed to meet the varying needs.

A construction of recuperator core segments is provided which insures proper assembly of the components of the recuperator core segment, and of a plurality of recuperator core segments. Each recuperator core segment must be constructed so as to prevent nesting of fin folds of the adjacent heat exchanger foils of the recuperator core segment. A plurality of recuperator core segments must be assembled together so as to prevent nesting of adjacent fin folds of adjacent recuperator core segments.

A tray (10, 40, or 50) for shipping, displaying and vending containers of product has side walls (12, 13 or 12′, 13′), end walls (16, 17 or 16′, 17′), an open top, and a bottom wall (11). The sidewalls have an open center portion (15) through which product (P) held in the tray is easily visible and accessible for removal from the tray. The end walls have first and second laminated end wall panels (21 and 22, 23, or 57, 58 and 70, 71), and in one embodiment the sidewalls have laminated sidewall flaps (59, 60 and 62, 63), forming double-wall constructions. A full-height reinforcing divider (18, 19 or 18″, 19″) extends vertically along an inner surface of each end wall substantially midway of the width thereof to reinforce the tray and prevent it from telescoping into another tray when they are stacked. The dividers at opposite ends of the tray are spaced from one another, defining a large opening between them through which product may be removed through the front from the back of the tray without having to lift the product, whereby product can be removed from the back of the tray through the front when multiple trays are stacked on top of one another.

The invention provides a tipping bucket type bird repelling device. The tipping bucket type bird repelling device is used for being installed on a cross arm of an electric pole. The tipping bucket type bird repelling device comprises a covering part. The covering part is provided with a first connecting base, a supporting rod and a bird repelling baffle, wherein the first connecting base is used for being detachably connected with the cross arm, the supporting rod is arranged on the first connecting base, the bird repelling baffle is used for covering the cross arm, and the bird repelling baffle is arranged on the supporting rod in a rotary mode through a rotating part. According to the tipping bucket type bird repelling device, birds can be effectively repelled under the condition that an overhead conductor is electrified, and the lives of the birds can be prevented from being threatened.

A one-piece container formed from a single unitary blank of corrugated paperboard has a bottom wall, opposed side walls and inwardly inclined opposed end walls. Stacking tabs project upwardly from the end walls and tab locks in the bottom wall receive the stacking tabs of a subjacent container when the containers are stacked on top of one another. A reinforcing corner post extends the full height of the container in each corner. The corner posts are formed by panels extending from opposite ends of the end walls, wherein the panels include a first panel foldably joined to an end of an associated end wall and adhered to an adjacent side wall, a second panel foldably joined to the first panel and extending diagonally across the corner, and a third panel foldably joined to the second panel and adhered to an adjacent side wall.

The invention belongs to the technical field of high-voltage safety, and especially relates to a mechanism for preventing birds from nesting on a wire based on a compression bar structure. The mechanism comprises a wind pendulum, a spherical hinge, a telescopic link, an oil cylinder, a cross bar, an oblique supporting rod, a hinged sliding sleeve, an inertial spring, an inertial sliding sleeve and the wire, wherein the power of the mechanism comes from natural wind energy; when the wind acts on the wind pendulum, the wind energy is converted into the mechanical energy, and the telescopic rod and the spherical hinge make the wind pendulum rotate and swing downwards without interference; hydraulic oil in the oil cylinder is compressed, and the mechanical energy is converted into the pressure energy, so that the cross bar connected with the oil cylinder moves, and the liquid pressure energy is converted into the mechanical energy; and after that, the power is transferred to the inertial sliding sleeve via the cross bar, the oblique supporting rod, the hinged sliding sleeve and the inertial spring, so that the inertial sliding sleeve slides on the wire in a reciprocating way to knock off sundries on the wire used for nesting by the birds. The mechanism for preventing the birds from nesting on the wire based on the compression bar structure provided by the invention utilizes the function of the natural clean energy, that is wind energy, so that the mechanism can continue to play a role, and the structure is reliable and the practicability is stronger.
