Title: Patch for skin tests
IPC: A61L15/58
Filed: 1977-12-30
Abstract: An adhesive patch for skin testing using chemical substances such as dinitrochlorobenzene (DNCB), oxazolone, beryllium fluoride, paraphenylenediamine or other like allergens, the allergen being mixed with an excipient which melts when placed in contact with the skin. The adhesive patch provides a sandwich-type construction that includes an adhesive layer, a first foil layer with one side against the adhesive layer, a layer of liquid impermeable synthetic mterial on the other side of the foil face, an absorbent disc on the synthetic layer, the allergenic material on the absorbent disc and a second foil layer overlying the absorbent disc and forming an air-tight seal with the first foil layer. In use the second foil layer will be removed and the patch adhesively applied to the skin of a user without fear of sensitization of the person handling the patch test. The patch test is formed by a continuous process wherein a first web of foil that has been covered with a web of synthetic material is advanced longitudinally, separate discs of absorbent material being placed on the synthetic material side of the web at regular intervals as the web is transported longitudinally the test material diluted in solvent is deposited onto each absorbent disc as same passes a dispensing station, the solvent is evaporated before sealing, and a second web of foil is fed to overlie the first foil web and is then heat-sealed thereto to form discrete pouches in each of which is located an absorbent disc, the sandwiched webs are severed to provide individual units that are then deposited on a web of adhesive patch material in spaced relation, a web of protective material is applied to the adhesive patch material with the spaced units located between said latter two webs, and the further sandwich is severed to produce completed individual units.

Title: Process for the preparation of viscose and process for the spinning of the viscose thus obtained
IPC: D01F2/06
Filed: 1980-06-12
Abstract: A process for the xanthation of alkali-cellulose comprises the reaction of the alkali-cellulose with CS2 in excess with respect to the desired xanthate substitution degree at a pressure which increases from the initial 110 mm Hg to about 400-500 mm Hg and at a temperature increasing from about 21 DEG C. to about 23 DEG -25 DEG C. The unreacted CS2 is removed from the reactor, once the desired xanthate substitution degree is reached, by application of a vacuum.

The viscose obtained has reduced content of compounds capable of forming elementary sulphur. The regenerated cellulose yarn has improved characteristics as to the sulphur content and degree of whiteness.

Title: Gravure screen and method of making the same
IPC: G03F5/12
Filed: 1981-08-25
Abstract: The present invention relates to a gravure screen and method of making the same and particularly to a gravure screen and method of making the same in which in the case that a gravure printing plate is made using a planographic or relief half-tone positive, the gravure screen is combined with the half-tone positive. Transparent or opaque lines of the gravure screen in accordance with the present invention are formed by irregular patterns, and the presence of this irregularity does not cause to form a moire pattern even if the gravure screen is combined with the planographic or relief half-tone positive formed by regularly aligned dot patterns. It is therefore possible to combine the gravure screen of the present invention with a half-tone positive of any screen angle, and a gravure printing plate can be made by only one gravure screen even in a plurality of half-tone positives having different angles. In addition, the gravure screen of the present invention can be used in the conventional gravure process, and even if a design having regular patterns is present in an original, the moire does not occur between the design and the gravure screen.

Title: Control for the clutch and/or the brake of a press.
IPC: B30B15/14
Filed: 1981-10-30
Abstract: A control arrangement for a clutch and/or brake of a press, with the control arrangement including at least one of a clutch cylinder piston unit and a brake cylinder piston unit which opposes braking forces until a desired rotational speed is reached. The cylinder-piston units may be operationally controlled by at least one valve before the desired rotational speed is reached. The control arrangement is driven by at least two different pressures, with one of the pressures being at least approximately equal to a maximum clutch pressure or at least approximately equal to a pressure release, and the other pressure being a partial pressure which lies above a minimum response pressure of the clutch or below a counter pressure which triggers a minimal response pressure of the brake. After an intermediate pressure is reached which, in the case of a clutch operation, lies between a value above the partial pressure and the clutch pressure, and with a brake operation, between a value below the partial pressure and a pressure release and, during a clutching and braking operation the pressure may still be switched, prior to a reaching of the desired rotational speed, to the partial pressure for a time period that it takes to obtain the desired rotational speed. The control arrangement may also be utilized in a combination clutch-brake construction with the respective pressures being set in the control arrangements on the basis of a program control which is operable in dependence upon operating parameters of the press.
