A paper ring (10) comprising a generally double toroidal shaped flexible loop (12) having abutting ends (14), (16) which can be moved apart to fit within aligned punched holes (18) in a stack of loose-leaf pages (20), so as to temporarily hold the loose-leaf pages (20) together and allow a person to turn the loose-leaf pages (20) fully around, making it easier to grasp and rear information (22) on all of the loose-leaf pages (20).

A paper cutter having a paper stand, a pair of arms of identical length attached to the paper stand defining a contacting position and a separating position, a guide rail connected to the pair of arms such that the guide rail is parallel to the paper stand, a slider slidably attached to the guide rail. The slider has a rotary blade fixed on a holder, the blade being capable of being moved up and down within the slider against a spring, the blade exposed by being pushed down when the slider is in...

A security paper indicates exposure to a solvent by a solvent resistant color signal. A metal mordant dye first co-reactant and a mordant dye second co-reactant form an organic solvent-insoluble colored reaction product when the paper is washed with an organic solvent. The metal mordant dye first co-reactant and a mordant dye second co-reactant are chemically isolated from each other so as to prevent the coordinate covalent bond from forming until the paper is washed with an organic solvent. The...

A method and a color mixture for shading paper, and a shaded paper that comprises or consists of one or more layers made of the same or different pulps, which paper is intended to be used in connection with foodstuffs. The pulp or paper layer is treated with a color mixture of at least two optically cooperating pigments that are approved for foodstuffs, one of which is quinacridone red with the FDA registration details C.I. pigment violet 19, C.I. No. 73900 (Code of Federal Regulations, Food and...

The specification discloses a synthetic paper composite web containing a relatively smooth, dense top layer comprising synthetic pulp, a relatively soft non-woven base layer of synthetic filaments and a low density polyolefin film layer substantially continuously interbonding the top and base layers together along their interface. An advantage of the composite of the invention is that it is substantially weather resistant, strong, recyclable and compatible with a range of inks and printing syste...

Speckle-patterned paper is produced on the paper machine without the use of printing techniques by first preparing speckle-forming material and then introducing this into a contrasting color papermaking furnish. Paper is then made from the speckle-containing furnish in the normal way. The speckle-forming material is produced either by agglomerating a mixture of papermaking fibre, particulate pigment and, preferably, a latex or other binder or by dry comminution of cellulose fibre aggregates in t...

A wiping implement suitable for use as a bath tissue can be formed into sheets, each sheet comprising at least one ply of a paper web having a basis weight of at least about 25 lb/3000 square feet. The sheet can have a width of at least about 4.5 inches and temporary wet tensile properties. The sheet of the present invention can have an area of at least about 30 square inches. In a multiple ply embodiment, the sheet can have an optimized basis weight of at least about 42 lb/3000 square feet whil...

A paper holder (100) comprising a base (10), a pair of front and rear jaws (21 & 22) provided on the base (10) for gripping a sheet of document by its lower end to holder generally upright. A hinge (30) connects the front jaw (21) to the base (10) for pivotal movement relative to the rear jaw (22) for opening and closing the jaws (21 & 22). A spring (35) resiliently biasses the front jaw (21) towards the rear jaw (22). The front jaw (21) has an upper surface (23A) extending over and above the ba...

A paper chute that is attachable to a desk or the like that includes an intake chute positionable the level of the desk and a discharge chute which is orientable toward the opening of a trash can so that papers and the like thrown into the chute opening are directed into the trash can.

A drive unit for a knife roller of a shredder having an electric motor to which a motor reduction gear transmission is attached. Recesses are located on both sides of the plane sides of the intermediate gear wheel. Each of the stop surfaces, which are located across from each other, work in cooperation with the in corresponding catch pin on the corresponding free shaft end of the knife roller drive shaft. The stop surfaces and their catch pin represents a free wheeling clutch for forward and rev...
