Abstract: A roller press includes two rollers each having a first end extending through a first sidewall of a roller unit frame so as to be connected with a gear unit which is cooperated with an operation handle, and two respective second ends of the two rollers extend through a second sidewall of the roller unit frame so as to form an open-type entry. A close-type entry is defined between the two rollers located between the first and second sidewalls of the roller unit frame. The two entries are able to press the paper products of different widths.

Abstract: A method of generating an integrated module directly by the design patterns of a cardboard, a method of modularizing a variety of paper crafts can transform to a method of combining a set of modules into an integrated module via pattern designs. In addition to using double etching to etch directly the cutting lines, perforation dots, embossments, and protrusion dots on a thick steel plate to be a male die of the module, the present inventions is characterized in that the differences of the fissures among the modules and the thicknesses of the plates are used to reach the effects of holes and extensions, and it has force points on the same level while it generates different effects at the same time.

Abstract: A method for directly forming a cutter mold with double etching and an apparatus thereof includes the following steps: a metal plate for being made, the cutter mold is tightly pressed with a light-resisting agent membrane first, an image of cutter mold drawing, which provides lines with widths thereof being one fifth or one tenth of the lines on the ink drawing of conventional cutter mold, is transferred to the light-resisting agent membrane. The thinner lines perform obstructing the etching liquid, which sprays toward the membrane to etch the work. Finally, the unnecessary membrane is peeled and two lateral sides of the formed cutter mold are etched with light etching liquid to complete the cutter mold with a sharp blade.

Abstract: A mold tool for paper relief engraving provides a mold cavity, a mold plunger and a folder for being detachably fixed with the mold cavity and the mold plunger at the inner sides thereof. The mold cavity and the mold plunger are doubly etched to create pattern nests and pattern projections respectively with smooth fine contours and edges such that the relief engraved paper can be tightly pressed in a way of the flat part of the paper being kept without wrinkles and deformation at the nests and the jut up part of the paper extending sufficiently. Hence, the relief engraved configuration presents outstanding sense of beauty especially for making a greeting card.

Abstract: A detachable roller mold press includes two rollers that can rotate relative to each other. The rollers are securely fastened to a predetermined location, which can drive a press mold or a knife mold plate. The roller mold press of the present invention is detachable so as to save storage space. The detachable roller mold press includes a roller mechanism, a chassis, a bottom cover and two bridges. The roller mechanism includes two rollers that can rotate relative to each other. The front and the rear portions of the chassis include an opening. The opening and the two rollers form a space for allowing a knife mold or a press mold plate to move therein. By rotating the two rollers, one can move the knife mold or the press mold plate to rapidly carve or engrave on a piece of paper or a piece of cloth.

Abstract: A press includes an arm mechanism to input force transferred to upper and lower rollers by a worm unit. The worm unit occupies less space so that even if the size of the press is increased, the worm unit can be used without too much change. The handle is located on a top of the casing of the press and is formed together with the casing of the press. A suction mechanism is located on an underside of the base part of the casing and is controlled by a lever. A platform is independently connected to the casing.

Abstract: A mold assembly for embossing thin products includes a first carrier with a female mold connected to an inside thereof and a second carrier with a male mold connected to an inside thereof. The female mold faces the male mold, and the thin product is sandwiched between the male and female molds. A window is defined through the first carrier and located corresponding to the apertures of the female mold so that the user may color the thin products via the apertures of the female mold before the products are removed from the mold assembly.

Abstract: A paper cutting device includes a guide member which is has one end pivotably connected to the base by a hinge and the other end of the guide member is positioned by two positioning rods. A box for receiving the spare cutting blades and the folding line makers is connected to the base. A cutting blade unit and a folding line maker are movably engaged with a groove in the guide member. The cutting blade of the cutting blade unit and the folding line maker can be replaceable. The cutting blade unit includes a protection case so that the cutting edge is hidden when not in use. The folding line maker has a dull edge which creates a folding line on the paper sheets.

Abstract: Provided are enhancing transdermal absorption compositions useful in transdermal absorption of progestins including progesterone and optionally an estrogen for contraceptive or hormone replacement and dosage forms using the novel enhancing compositions. The enhancing compositions comprise a combination of a lower alkyl ester of a polycarboxylic acid, an aliphatic monohydroxy alcohol and an aliphatic diol. Also provided are processes of administration of progestins and optionally estrogens using the novel dosage forms.

Abstract: This invention relates to a novel transdermal absorption dosage unit comprising a backing layer, an adjoining layer of solid polymer matrix in which estradiol or another steroidal pharmaceutical having estrogenic activity is microdispersed; and a biologically acceptable adhesive means by which the dosage unit adheres to the skin of the subject being administered said estradiol or another said steroidal pharmaceutical and adapted to permit transdermal absorption of said estradiol or another said steroidal pharmaceutical. Additionally, the invention relates to improved estradiol or other estrogenic steroid maintenance therapy.
