Abstract: Orthodontic pliers comprised of two asymmetrical components that are subapically and pivotally joined in a first main embodiment. Each of these elongate pieces is irregular in shape, unequal in length and the jaws are asymmetrical jaws relative to each other. The pliers when heated are used for producing or modifying bumps on a thermoplastic retainer. One of the jaws has a throughbore or blind bore for receiving the bump forming end of the other jaw. The jaw with the bump forming end is shorter and curvilinear so that the only part of that jaw that comes in contact with the retainer is the bump forming end. Additionally, the bump forming end may be of different shapes in order to produce different shaped bumps such as ramps, logos, logo pockets, fluoride pockets, bite plates, rectangular shapes for the retention of blocks to be wired, and hooks for elastic banding, depending on the needs of the individual patients. The pliers are heated to a temperature range of approximately 325° F. to 350° F.

Abstract: The subject matter of the invention is an embossing press, including an embossing roller and a counter cylinder, for producing embossed seams by joining at least two paper layers or fleece layers, arranged one above the other and conveyed in a straight line. For this, the embossed seams extend at a slant or at a right angle relative to the conveying direction of the paper layers or fleece layers.

Abstract: A flexible counter for an embossing system provides resilient support under a sheet which opposes pressure from a contoured die forming an embossment in the sheet. The flexible counter includes a resilient mat and a fixed bolster which supports the mat. The bolster has a peripheral wall which extends around sides of the mat so that an upper portion of the mat protrudes above the peripheral wall. In addition, the bolster includes support surfaces bounded by recesses. The support surfaces support a bottom surface of the mat, and the recesses receive bulging portions of the mat when compressed under pressure from the die.

Abstract: A sheet material, such as a bank note, having tactile indicia therein, the tactility of which is resistant to deterioration and useful for assisting persons with impaired vision to identify one or more predetermined characteristics of the sheet material such as a bank note. The sheet material has therein at least one embossment forming the indicia and comprises a first surface and a second surface, with one of the surfaces defining a cavity in the area of the embossment. A layer of reinforcing material is provided to at least the area of that surface which comprises the cavity. Once the reinforcing material is dried and/or cured the embossment (indicia) is strengthened by the layer of reinforcing material and thereby rendered more durable when the bank note is subjected to the wear of circulation. The reinforcing material may be selected from the group consisting of varnishes, inks, adhesives and caulking compounds.

Abstract: A motor driven seal device for impressing a design permanently on paper using a seal clip assembly including a male die and matching female counter from a new or existing manually operated seal. The invention incorporates a motor with housed gearing which operates a drive rod and compression sleeve. A frame extends from a base (or platen) onto which the motor is mounted. The motor shaft drivingly engages the drive rod which extends from the motor toward the platen. A compression sleeve capable of travel along the length of the drive rod in response to rotation of the drive rod engages the drive rod adjacent the platen. The seal clip is inserted between the compression sleeve and the platen. Rotation of the drive rod by the motor advances the compression sleeve toward the platen thereby pressing the die of the seal clip into matching engagement with the counter. A piece of paper inserted between the die and counter of the seal clip during this operation is embossed with the indicia contained on the die.
