Title: Process for the manufacture of a new derivative of hexamethylenetetramine
IPC: C07D487/18
Filed: 1921-05-18
Abstract: Gall acids difficultly soluble in water are combined with hexamethylenetetramine to form a water-soluble compound.  The acids may be dissolved in alcohol, any slimy impurities separated, and an equimolecular quantity of hexamethylenetetramine dissolved in the minimum quantity of alcohol, added.  The alcohol is then evaporated in a vacuum.  In another method, the gall acids are ground with a concentrated aqueous solution of hexamethylenetetramine and the product desiccated in a vacuum. Or the mixed powdered constituents may be agglomerated, the moisture imparted during the process being sufficient to induce combination.  The product is useful in the treatment of gall-stones.  Its aqueous solution is clear and gives with strong acids a precipitate which is first milky and then white and is insoluble in benzine.

Filed: 1919-06-02
Abstract: 127,823. Wurstemberger, F. von, and Frei, H. A. June 1, 1918, [Convention date]. Corrosion, preventing. - Selective corrosion of copper or copper alloy tubes or machinery parts in contact with sea or other salt water caused by electrolytic action is prevented by the addition of a hydrolytically decomposing acid salt such as aluminium chloride, ferric chloride, or ferrous chloride, thus assisting the polarization of the surfaces acting as anodes and equalizing the potential of the copper surfaces. The salt may be formed in the water and using a suitable metallic anode, the cathode products being conducted away. Ferrous chloride is added to the cooling water of a condenser 1 by passing a current from an iron anode 4 through the water to a cathode 5, which is surrounded by a clay pipe 7 having a side outlet 8 for discharging the cathode products. Instead of placing the electrodes in an open channel 3, they may be placed in an inlet pipe, the cathode products being discharged through a branch pipe. The current may be passed between non-conducting electrodes through a metallic conductor immersed in the water.

Patent GB-576476-A (GB)
Title: Preparation of therapeutic sera
IPC: C07K16/06
Filed: 1943-08-31
Abstract: Fibrin is precipitated from plasma by the addition of an organic substance having thrombic activity, e.g. clotting globulin or cephalin.  Specification 556,024 is referred to.ALSO:Stable therapeutic serum is obtained by bleeding into a small amount of an anticoagulant, separating the blood cells from the plasma, adding to the plasma an organic substance having thrombic activity, e.g., clotting globulin or cephalin, and removing the formed fibrin clot from the clear, stable serum.  Animals, hyper-immunized with an appropriate antigen, may be bled into a minimum amount of an anticoagulant such as sodium citrate.  The red and white blood cells are separated by gravity or centrifuge and the clear plasma is treated with sufficient calcium chloride to react with the anticoagulant.  Clotting globulin is then added to the plasma which is agitated during its clotting, the fibrin floating on the surface of the liquid being removed.  The process may be used in the preparation of feline distemper, dog distemper, antihemorrhagic septicemia (equine origin), and hog cholera sera.  Specification 556,024 is referred to.

Title: Method and apparatus for applying closures to containers
Inventor: HARMON SHEPARD LEWIS
IPC: B67B3/20
Filed: 1966-04-01
Abstract: 1,145,131. Capping containers. OWENS-ILLINOIS Inc. 1 April, 1966, No. 14501/66. Heading B8T. Containers 10 are moved continuously by a conveyer (11), Fig. 1 (not shown), to engage the leading inner edges of caps 9, each cap being supported at an angle to the plane of the container top which engages it and rotated in the unscrewing direction by means of stops 38 as it is entrained on the container; but subsequently the cap is turned in the screwing down direction as the container continues forward, until the cap is screwed fully home. The caps 9 are gravity fed from a shoot 30 via supporting rails 37, being retained in the receiving pockets 42 of the cap stops 38. The ends of the cap stops 38 are tapered, the left hand one 44 in the direction of travel having a friction member 45. As the cap 9 is pulled clear by the container 10 the greater frictional drag exerted by the stop 44 leads to a reverse rotation as the cap 9 assumes a horizontal position on the container 10. The cap is thus slightly backed off the threads on the jar neck, releasing any lugs which may have become hooked under the threads of the jar. A hold-down shoe 50 is provided between the cap stops 38, engaging the cap top panel and holding it in Contact with the jar following its emergence from the cap shoot 30. The shoe 50 is supported by a boss 51 secured to an arm 52, which pivots about a pin 53 and has an integral counteracting arm 54 biased by a spring 55, ensuring engagement of the hold-down shoe 50 with the cap top panel. A levelling plate 60 is engageable with the cap top panel, being lowered by the arcuate movement of an arm 61 pivotally attached to an upstanding support 62 mounted on plate 60 and pivoted about the pin 53, the plate being maintained horizontal in any position by the movement of a guide pin 67 attached to the support 62 in an arcuate slot 68. The lower surface of the plate 60 has a portion constituting a friction member 71 which may protrude to engage the corresponding area of the cap 9 more effectively as it passes the plate 60, thereby imparting an orienting rotation to the cap, which prevents damage to the closure elements on the cap 9 or jar 10 when downward pressure is exerted in the sealing process. When positioned on the jar 10 the cap 9 is rotated into sealing engagement by contact with a pair of oppositely driven endless belts 81, 82. In an alternative embodiment, Fig. 6 (not shown), the pivoted cap stops are replaced by modified stops (87) mounted on a back plate (88) and screwed to a flexure plate (89).

Upon actuation of firing pin 20 a cartridge percussion cap 18 ignites the self-combustible charge, comprising colloided nitrocellulose for example, in the cartridge 16 the gases from which build up a high pressure in the combustion chamber 1, the latter being provided with a safety device consisting of a disc 11 arranged to burst at a predetermined pressure. From chamber 1 the gases pass through the trap 6 of a grid formation that prevents any large fragments of powder passing into the engine cylinder 3, and the orifice 5 from which the gases emerge at a slightly reduced pressure into channels 25 and 32 thereby causing valve 27 to leave its seat and enabling the gases to enter the cylinder 3 to start the engine. The channels 25 and 32 are contained in the member 2 that is screwed into the top of chamber 1, the channel 25 embodying a disc safety device, 11a which is arranged to operate at a lower pressure than the device opening into the chamber 1. A spring 30 is located between a shoulder in the member 2 and a ring 31 on the valve spindle 26; the valve 27 is closed by spring 30 to prevent blow-back on the compression stroke of the engine.
