Title: Process of manufacture of sulfur containing proteincompounds
IPC: A61K38/01
Filed: 1935-06-21
Abstract: Proteins and amino-acids are treated, in the presence of alkali equivalent to an hydroxyl ion concentration not greater than that of a saturated aqueous Ca(OH)2 solution, with carbon disulphide, and the products oxidized by contact with air, if desired in the presence of catalysts such as sulphur, metals, e.g. iron, copper, and mercury, or their sulphides or salts, or peroxides.  Thiohydantoin derivatives are obtained in the form of their alkaline earth compounds.  They can be transformed into other metal compounds with, e.g. Cu, Hg, Fe or Ag oxides or sulphates.  The derivatives are used therapeutically, for preventing bacterial growth, and as chicken food.  In examples: (1) gelatine is boiled with lime water, the solution refluxed with CS2, and the product treated with pyrolusite, iron, iron or zinc sulphide, or iron sulphate in presence of air; (2) sulphur is used in the oxidation step of (1); (3) glycine is treated in similar manner; (4) alanine, phenylalanine, histidine, or "thyrosin sulpho acid" is dissolved in Ca(OH)2 solution. After treatment with CS2, and boiling with sulphur, red solutions are obtained which dye wool and silk; (5) metal compounds of the products of (1)--(4) are prepared.

Abstract: 808,081. Centrifugal pumps. SIGMUND PUMPS Ltd. May 17, 1957 [June 8, 1956], No. 17845/56. Class 110 (1). In a self-priming centrifugal pump of the kind in which a discharge chamber adjacent the impeller chamber is divided by a dividing member to provide flow passages such that liquid delivered through one of the flow passages may recirculate towards the impeller through the other flowpassage during priming, the liquid being discharged through both passages during normal operation, the impeller axis is vertical and the lower end of the discharge chamber extends around part of the circumferential length of the impeller chamber, and the dividing member extends upwards in the discharge chamber with its upper edge above the plane of the impeller chamber and below the outlet from the discharge chamber. The discharge chamber 15 is bounded by vertical walls 17, 18 concentric with the impeller 12, and at its lower end is divided by an arcuate wall 22 extending upwardly from a horizontal wall 16 which separates the discharge chamber 15 from the suction chamber 2. The wall 22 extends from the end wall 20 of the discharge chamber 15 adjacent the cut-water 21 and has a vertical free end 23. Bracing webs 25, 26 joining the wall 22 to the walls 17, 18 extend from the free end 23 and are of limited length so that apertures 27, 28 are provided between their free ends and the wall 20. During priming, a mixture of liquid and gas passes from the pump intake (not shown) downwardly through a passage 3 to the suction chamber 2, and is delivered by the impeller 12 upwardly through the aperture 27. The gas separates from the mixture and is discharged in the direction A<SP>4</SP> through the outlet 19 of the discharge chamber 15 while the liquid flows over the upper edge 24 of the wall 22 and down through the aperture 28 in the direction A<SP>5</SP> and thence between the walls 16, 26 in the direction A<SP>6</SP>, finally passing in the direction A<SP>7</SP> around the free end 23 to mingle with the mixture of liquid and gas in the impeller chamber 6 to increase the proportion of liquid therein. On completion of priming, liquid delivered by the impeller 12 flows at both sides of the wall 22 in the direction B<SP>2</SP> and then upwardly through the apertures 27, 28 towards the outlet 19. The walls 7, 16, 22, the webs 25, 26 and the cutwater 21 may be formed as a unitary casting which can be replaced when worn. As shown in Fig. 3, two inlet passages 3 may be provided, the inlet not in use being covered by a closureplate.

Abstract: 1,026,913. Fluid pressure servomotor control system. J. B.KATELBAND. May 10, 1963 [May 11,1962], No. 18564/63. Heading G3P. A main valve controlling the discharge from or supply to a container fed with liquid is actuated by fluid pressure, the supply and exhaust of which is controlled by a pilot valve whereby a substantially constant liquid level is maintained in the container. The pilot valve comprises a diaphragm 7 Fig. 3 (not shown) 7 loaded by a spring 12 and connected to a smaller diaphragm 8 to form a chamber 11 connected to the container by a pipe 10. A conduit 19 leads to the main valve and is connected to a fluid supply 5 or exhaust 25 by a ball valve 21 or valve closure 16 respectively. The ball valve 21 is actuated by a rod 23 fixed to the diaphragm and the closure 16 is carried by the diaphragm or by a shelve which has limited axial movement relative to the diaphragm. In operation for discharge, if the liquid level rises the pressure in the chamber 11 increases due to the increased lead and the diaphragm move upwards to open valve 16 allowing the main valve to open. If the level falls, the diaphragms move downwards to open the ball valve 21 to admit fluid pressure to close the main valve. The main valve is formed by a diaphragm sleeve which closes on to a core. For supply to the container, the action of the valve 16 and 21 are reversed.

As illustrated, the devices are slidable on guides in the form of circular section rods 15, by means of two couplings 16, 17. Coupling 17 permits vertical adjustment and coupling 16 permits horizontal adjustment. Annular members 13, 14 of each device are movable axially relative to each other by means, not shown. In operation, after carcass plies have been applied to the collapsed drum and bead core retaining and ply turn-up assemblies 10, the devices are moved, with bead cores thereon, to the position of Fig. 3. The drum is then expanded and simultaneously the devices are moved nearer the drum, the cores not being in contact with the carcass plies until the drum is fully expanded. Annular members 14 hold the bead cores against the carcass plies while the members 13 are moved away from the drum, annular bags 11 being inflated. Finally, the bead support rings 12 are expanded to clamp the bead cores, the members 14 are removed, and the carcass ply edges are turned up around the bead cores. Axial movement of shaft portion 9a, and the associated device 1 and assembly 10 away from the drum enables the carcass blank to be removed, the drum and the rings having been returned to their minimum diameters.
