Title: Base for film-coating pharmaceuticals and method for preparing same
Inventor: KOBAYASHI KAZUTO
IPC: A61K9/28
Filed: 1991-08-26
Abstract: A  cellulose  ether  having  a  low  degree  of polymerization  is  used  as  a  base   for  film-coating pharmaceuticals.  The cellulose ether having a low degree of polymerization obtained by causticizing a pulp having a  copper  number  of  not  more  than  0.4  g,  adding  an etherifying agent to form a cellulose ether having a high degree of polymerization, then refining it with hot water, drying by heating,  finely pulverizing the dried cellulose ether and depolymerizing the fine powder has high whiteness and is thus suitable for use as a base for film-coating pharmaceuticals.  The  viscosity of  a  2%  aqueous  solution of the cellulose having a low degree of polymerization is preferably not more than 20 cSt at 20  °C.  The cellulose having a  low degree  of  polymerization  is  selected  from methyl  cellulose,  hydroxymethyl  cellulose,  hydroxyethyl cellulose,  hydroxypropyl  cellulose,  hydroxypropyl  methyl cellulose and hydroxybutyl methyl cellulose. The cellulose ether having a high degree of polymerization is pulverized within one  minute  in  an  impact  pulverizer  after  drying it at a temperature of atmosphere of not more than 100 °C and that of the cellulose ether per se of 40 to 80 °C to control the moisture content thereof to 1 to 5% by weight, and  thus  a  cellulose  ether  having  a  low  degree  of polymerization and high whiteness can be obtained.

Patent CA-2100219-A1 (CA)
Inventor: ROPER RALPH E
IPC: B21D26/02
Filed: 1993-07-09
Abstract: A self-contained apparatus for forming metal sheet is adapted for operation within a standard double action press having a base and outer and inner vertically reciprocating slides and includes a basic die mountable to the press and specific tooling replaceably mountable to the basic die.  The basic die includes a riser mountable to the outer slide, a manifold mounted atop the base of a tub, and hydraulic cylinder assemblies mounted atop the base and in connection with the manifold and mechanically actuatable by the inner slide for providing pressurized fluid to the specific tooling.  The specific tooling includes mating upper and lower dies connected to the riser and manifold, respectively, and movable between open and closed positions.  A sheet metal blank positioned upon the lower die is wrapped around the upper die as the upper die is moved down to a closed position by the outer slide, the blank being clamped between the upper and lower dies whereby the periphery of the blank is gripped between a male and female bead mounted all around a part print cavity in the upper and lower dies, respectively.  The outer slide then dwells while the inner slide moves down, engaging and actuating the cylinder assemblies, causing hydraulic fluid to be forced into a region between the clamped blank and the lower die, the blank being formed into the part print cavity defined in the upper die.  The male bead exerts varying control on the sheet to allow it to stretch across portions of the cavity while flowing into other portions of the cavity.  A locking mechanism prevents the bending of the dies and holds the dies in a closed position thereby assisting the engagement of the male bead with the female bead.  As a safety feature, the mechanism is configured to automatically open when the die cavity is moved up.  The locking mechanism allows the use of high pressures to make large parts, such as car hoods, doors, deck lids, and quarter panels in conventional currently available double action presses.

Title: Improved caffeine recovery from activated carbon
Inventor: SIPOS STEFAN
IPC: A23F5/22
Filed: 1993-07-16
Abstract: IMPROVED CAFFEINE RECOVERY FROM ACTIVATED CARBON Abstract The invention relates to a process for recovering caffeine from caffeine-loaded activated carbon and which is charac-terized in that the caffeine destroying activity of the activated carbon is reduced before or after loading with caffeine. The activated carbon can to that end be treated with acids, buffers, complexing agents, redox substances, caffeine and other xanthine derivatives. The caffeine recovery yield can be considerably increased by this means.

Patent CA-2103840-A1 (CA)
Inventor: OKAZAKI IWAO
IPC: G11B5/73
Filed: 1993-08-11
Abstract: ABSTRACT OF THE DISCLOSURE       Disclosed is a biaxially oriented film and a laminated film containing specified organic particles at a content of 0.001 to 20% by weight.  The strength when deformed by 10%          (S10) of the organic particles is in the range of 3 to 30 kgf/mm2, the thermal decomposition temperature for causing 10% loss in weight thereof is not lower than 350 °C .  The weight average diameter thereof is in the range of 0.005 to 5 µ m.  Since the organic particles have a good affinity with the matrix resin of the film and a good thermal resistance and the hardness of the particles is appropriate, desired protrusions hardly chipped and having an appropriate hardness for hardly scratching a magnetic-surface can be formed on a film surface easily and uniformly.          Therefore, a film excellent in abrasion resistance and scratch resistance at a high running speed and excellent in running durability can be obtained, which is useful particularly as a base film of a magnetic tape.
