Title: Thiamine complex with styrene-maleic anhydride
IPC: A61K47/48
Filed: 1964-12-28
Granted: 1971-05-15
Abstract: Therapeutic thiame complex which is stable and tasteless is formed with styrene-maleic anhydride copolymer in a suitable non-aq. solvent e.g. acetone, ethylene dichloride or chloroform. The solvent is then removed by spray or vacuum drying. Pref. 35-45 parts wt. thiamine (as free base) to 65-55 parts wt. copolymer are used. The product is of variable composition, and forms a white amorphous powder without the bitter taste associated with thiamine itself. The complex is insoluble in water and artificial gastric juice but soluble in artificial intestinal juice prepared according to Jap. Pharm. (7th edition). It is therefore suitable as an enteric thiamine prepn.

Abstract: 1,054,456. Chlorine dioxide. ADCO (OVERSEAS DEVELOPMENTS) Ltd. Oct. 1, 1964 [Oct. 10, 1963], No. 40078/64. Heading C1A. Chlorine dioxide is produced by reacting an aqueous solution of an alkali metal chlorate with hydrochloric acid in a reaction zone to produce chlorine dioxide, chlorine and alkali metal chloride while maintaining the concentration of alkali metal chloride in the reaction zone below saturation, passing at least a portion of the solution from the reaction zone to an enriching zone, feeding alkali metal chlorate into the enriching zone so as to maintain a concentration of alkali metal therein in excess of that required to saturate the solution in the enriching zone with respect to the alkali metal chloride so as to cause precipitation of the chloride in the enriching zone, conducting enriched solution from the enriching zone to the reaction zone, and removing solid alkali metal chloride from the enriching zone. The process may be carried out continuously or batchwise. Hydrochloric acid, gaseous or in aqueous solution, is added to generator 10 at 17 and reacts with sodium chlorate in aqueous solution at 40+5 C. without precipitation of sodium chloride. Chlorine dioxde is withdrawn at 18 by bubbling a gas inert to chlorine dioxide, e.g. air or chlorine through the solution in the generator. A part of the solution is pumped by pumps 14 through pipe 13 to enriching chamber 11 which contains a bed of solid sodium chlorate added at 20. Precipitated sodium chloride is withdrawn at 19. The enriched solution is returned to generator 10 via pipe 12. Overflow pipe 15 permits the withdrawal of solution from generator 10 The overflow may be returned to an electrolytic process for conversion to sodium chlorate. Alternatively, water is removed from the solution passing from generator 10 to enriching chamber 11 by evaporator 16.

Abstract: 1,107,570. Stethoscopes. CARDIOSONICS MEDICAL INSTRUMENTS CORPORATION. 12 Aug., 1965 [19 Nov., 1964]. No. 34572/65. Heading A5R. In a stethoscope head comprising a body member in which are formed two diametrically opposed sound receivers, symmetrically interposed between the receivers is a cylindrical recess in which is rotatably mounted a tubular cylindrical shaft constrained against axial movement relative to the recess. Extending through the body member from the apex of each receiver is a bore, one of which bores may be aligned, on rotation of the shaft relative to the body member, with one of two bores extending through the side wall of the shaft, the aligned bores being retained in alignment by resiliently loaded stop means which also obturates directly the other bore extending through the body member. The bores extending through the body member preferably are on an axis normal to the axis of the recess; the bores extending through the side wall of the shaft preferably are diametrically opposed so that each of these bores may be axially aligned with either of the bores extending through the body member. As illustrated in Figure 2, diaphragm receiver 12, comprising diaphragm 14 and threaded lock ring 15, and a diametrically opposed open bell receiver are formed in the body member of a stethoscope head. Extending through the body member from mouth portion 20 to blind end 19 is constant diameter cylindrical recess 16 in which is rotatably mounted stem 23 comprising tubular cylindrical shaft 24 integral with angularly offset reduced diameter portion 25 which frictionally engages sound tube 26 of conventional Y-shape leading to binaural ear pieces (not shown). Axial movement of the shaft relative to the recess is prevented by O-ring 29 of metallic or resilient, for example rubber or plastics, material located in rectangular annular grooves 27 and 28 respectively formed in the wall of the recess and in the bearing surface of the shaft. Extending through the body member from the receivers are coaxial equal diameter cylindrical bores 17 and 18 which may be aligned, on selective rotation of the shaft, with either of diametrically opposed bores 30 and 31 extending through the side wall of the shaft. The stop means comprises coil spring 32 having a first end mounted within the shaft on seat 33 and a second end carrying a stop 34 which comprises a spherical surface formed, for example, by a ball bearing of metallic or plastics material. The diameter of the ball bearing preferably is greater than the diameter of each of the bores extending through the body member but less than the diameter of one of the bores extending through the side wall of the shaft so that the ball bearing is resiliently urged by the spring partially outwardly of this latter bore thereby to close off one bore extending through the bodv member and to place the other bore extending through the body member in communication with the interior of the shaft.

In a homopolar machine of the kind in which the rotor 1 and stator 5 have annular, seriesconnected, conducting paths formed by the rotor and a copper tube 8, the tube 8 is located in the air gap 6 adjacent the rotor so that the path of the load current defines a toroidal volume lying substantially in the air gap whereby no flux due to load current is present in the ferromagnetic material of the stator. As shown, rotor 1, which is cup-shaped, forms part of a variable speed drive and is located with its base adjacent a similar rotor 3, the two rotors being secured to shafts 2, 4 and located in annular air gaps 6, 7 in the toroidal stator 5 which carries two field coils in annular cavities. 11, 12. Connection is effected between the bases of the rotors and between the ends of the side walls and the tube 8 by conducting liquid, e.g. an alloy of sodium and potassium and to facilitate the latter connections, the side walls increase in diameter towards the open ends of the rotors. Except where connections are required, the exposed surfaces of the rotors, the tube 8 and adjacent parts of the stator 5 are covered with a thin layer of insulating material. The liquid is introduced through a passage 13 and flows as a result of centrifugal force, through passages 18 to a trough 19 at the open end of rotor 1 and through passages 20 to the space between rotors 1, 3 and from there through passages 22 to a trough 23 at the open end of rotor 3. The liquid is then drawn off through passages 24 and re-circulated through the passage 13. A suitable gas such as nitrogen, fills the parts of the system not occupied by liquid. To maintain a connection between the open ends of the rotors, particularly rotor- 3, and the tube 8 at low speed, an outwardly extending flange 27 is provided which is slotted to retain the liquid. In operation, the shaft 2 is driven so that rotor 1 acts as a generator and produces current which flows through rotor 3 and causes rotation thereof. The drive between the shafts 2, 4 is controlled by varying the currents in the two field coils.
