Title: Blood purification
IPC: B01J47/04
Filed: 1965-04-23
Abstract: Disease-causing viruses are removed from blood by contacting the blood with a mixture of at least one cation exchanger and at least one anion exchanger, the ion exchangers having a particle size in the range of about 297-1190 microns.  The purification may be carried out during the process of collecting blood from donors or prior to the process of transfusing the blood into a human being.

Title: Process for the manufacture of complex iron compounds
IPC: C07F15/02
Filed: 1929-06-05
Abstract: 335,965. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). June 5, 1929. Complex iron compounds of aliphatic hydroxycarboxylic acids are prepared by treating a polyhydroxy mono- or poly-carboxylic acid of the pentane or hexane series or a salt thereof with iron or an iron compound, the reaction mixture being simultaneously or subsequently neutralized with a basic substance. Acids specified comprise pentonic acids (tetrahydroxy-monocarboxylic acids) such as hexane-tetrolic acid (2-methylpentane tetrolic acid), hexonic acids such as gluconic acid, trihydroxyglutaric acids, glucuronic acid, and tetrahydroxyadipic acids such as saccharic and mucic acids and their isomers. As basic substance may be used the alkalies and also nitrogenous bases such as ammonia, diethylamine, diethylaminoethanol, choline and quinine. The iron compound may comprise ferrous or ferric hydroxide or a corresponding water-soluble salt such as ferric acetate or ferric and ferrous chlorides. The preparation may be effected by dissolving iron in the acid and then neutralizing, or by mixing an aqueous solution of the acid or its salt with an aqueous solution of an iron salt and neutralizing, or by treating the acid or its salt with ferrous or ferric hydroxide and subsequently neutralizing. The iron may be present in the product in the proportion of one atom or iron to one molecule of acid or in such other proportions as 1 : 2, 2 : 1, and 3 : 1. The products, which can be isolated by precipitation or evaporation, are readily water-soluble and are useful therapeutically. Examples are given of the preparation of sodium ferrous and ferric gluconates, potassium-sodium ferrous and ferric saccharates, quinine potassium ferrous saccharate, and sodium iron mucate. Specification 326,231 is referred to.

Title: Improvements in or relating to apparatus for and method of filling containers
IPC: B65B1/40

Abstract: 643,475. Filling containers. CARTER, C. F. July 10, 1947, No. 18264. Convention date, Jan. 12, 1944. [Class 94(i)] Apparatus for filling containers 22, Fig. 1, with powdered or granular material and comprising a rotatably mounted hopper 30 having a plurality of spaced filling heads 32 with material feeding members 33 which are operated by driving members through a predetermined part of the rotation of the hopper, is characterized in that means are provided for varying the speed of rotation of the hoppers. Empty containers 22 are fed from a loading platform 63 onto a series of lifter plates 21 carried by brackets 20 mounted on conveyer chains 38, 40 driven by sprocket wheels 42 connected through reduction gearing and a variable speed pulley with a motor 48. The chains 38, 40 pass around sprocket wheels 19, 18 secured to a casting 13 carrying the hopper 30 and rotatably mounted on a collar 14. Each container is lifted into engagement with a filler head 32 during its travel around the sprockets 19, 18 by means of an arm 26 pressed by a spring 29 into engagement with a rod 23 carrying the plate 21. One end of the arm 26 is engageable with a cam track 27 which is shaped so that the container is in a lowered position except while being filled. Each filling head 32 contains a filling auger 33 carrying a pulley 36 driven by a belt 56 and a motor 53 the speed of which governs the quantity of material delivered to the container. Feeding rotation is imparted to the augers during a part only of their travel, by means of two pairs of idler pulleys 57, 58, Fig. 2, adjustably clamped about the frame and serving to direct the belt 56 out of engagement with the pulleys when the filling operation is complete. When the containers are to be filled with powder the auger feed may be assisted by alternately exhausting and introducing a gas into the container, resulting in an increase in the speed of packing and in the density of the pack, and eliminating dust. Suction is applied to the interior of a central shaft 12 to the upper end of which an apertured stationary ring 72 is clamped by a washer 17 (see Fig. 6). A surrounding rotating ring 76 is provided with apertures adapted to register periodically with apertures and air ports in the stationary ring 72 during their relative rotation (see Figs. 7 and 8, not shown). Each pair of a series of pairs of flexible air hose 80, 81 is connected to opposite sides of a modified filler head 132 provided with semi-circular screened openings 84, 85. The upper edge of a large mouthed container engages against an annular gasket 86 surrounding the openings 84, 85. To prevent clogging of the screens in these openings by the material when air is evacuated from the container, a pulsating effect is developed by causing air to pass first through one side and then through the other side of the screen.
