Title: Senna preparations
Inventor: FRIEDMANN CHARLES AUBREY
IPC: A61K36/00
Filed: 1957-10-02
Abstract: An extract of senna is prepared by extracting senna leaf or pod (with or without seed) with an aqueous organic solvent and adding to the separated liquid extract a metal salt and an anhydrous organic solvent to cause precipitation of a water-soluble product comprising the active principles of senna in intimate association with the metal ion of the salt.  The product may be further treated to remove metal ions, e.g. by precipitation with an organic acid, e.g. oxalic acid, or by means of a strongly acid ion exchange resin.  The product freed from metal ions may be further purified, e.g. by chromatography to give a stable crystalline product.  The aqueous organic solvent may be water and ethanol, acetone or isopropanol (50 to 80%, preferably 70% v/w.) and may also contain an organic acid.  The anhydrous solvent may be ethanol, acetone or isopropanol and the metal salt is preferably one of an alkaline earth metal, e.g. calcium.  The product may be incorporated in conventional pharmaceutical forms, e.g. tablets, pills, capsules, cachets, chocolate, chewing gum, pastilles, lozenges, granules, suppositories, enemas, syrups, elixirs or injections, alone or with other therapeutic agents.

IPC: H01F1/11
Filed: 1972-07-04
Abstract: 1398871 Ferrites XEROX CORP 4 July 1972 [8 July 1971] 31285/72 Heading C1J Ferrites are made by preparing a slurry of ferrite-forming metal oxides in a liquid, spray drying the slurry to form substantially spherical beads of mixed metal oxides and sintering the beads to form ferrite beads while maintaining the spherical shape and particulate nature of the beads. The metal oxides may be mixed in slurry form with conventional mixing equipment or they may be premixed before contact with a liquid medium. If the spherical beads are fired in a rotary kiln a flow promoting additive, e.g. Al 2 O 3  or ZrO 2  may be used to prevent beadto-bead agglomeration. Typical firing temperatures are 1150-1600 C. Nickel-zinc ferrite and manganese-zinc ferrites are preferred products since they provide magnetic permeability, conductivity and other properties useful in the electrostatographic art. Examples describe the preparation of Ni-Zn and Mu-Zn ferrites in which deflocculants and binders are used to alter the nature of the product.

Abstract: 1361012 Cassettes PRODUCTRON Inc 6 July 1971 [7 July 1970 7 Jan 1971] 31681/71 Heading G2X [Also in Division H5] A cassette for film sheets comprises a frame having a flat back plate, against which a pressure plate bears resiliently, the pressure plate having cam followers which can be moved by cam rods fixed to the frame so the pressure plate can be moved towards or away from the frame. As shown, the cassette 56 comprises a back plate 200, side and bottom walls 202, 204, 206, and a cover plate 208 having U-shaped springs 218 on its inner surface. Narrow passageways 226, 228 are formed in the side walls, and in these passageways cam rods 230 are slidably mounted. Each rod has a plurality of ramp cam surfaces 232 which can co-operate with a plurality of follower studs 234 extending outwardly from the side edges of a pressure plate 224, the plate bearing against the springs 218. By sliding the cam rod 230 downwardly from the position of Fig.9A to that of Fig. 9C (not shown), the studs 234 ride up the surfaces 232, so that the pressure plate 224 is moved away from the back plate 200. The cassette is intended for use with the film sheet dispenser claimed in Specification 1361014. When it is positioned in that dispenser, a pair of pins thereon engage the cam rods 230 which are pushed down, which opens the cassette, i.e. moves the pressure plate 224 away from the back plate 200, so allowing a film sheet to be fed into the space between them. To prevent light from entering the cassette, a light-trap is formed by a flange 233 on the upper edge of pressure plate 224, which flange engages in a slot in a flexible sealing member 235' secured to back plate 200. When the cam rods 230 are moved down to open the cassette, the movement of the plate 224 withdraws flange 233 from sealing member 235'.
